Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to a paging optimization method and apparatus. Background Art

[0002] Regarding the paging process, the existing protocol defines a Tracking Area (abbreviated as TA) and a Tracking Area Update (abbreviated as TAU) mechanism. During the execution of the TAU process, the terminal device needs to establish an RRC connection and send an uplink message, which is power-consuming for the terminal device. Moreover, the frequency of TAU is related to the size of the TA and the moving speed of the terminal device. The larger the TA, the smaller the frequency of TAU. However, the more base stations participate in paging, the greater the network power consumption. On the contrary, the smaller the TA, the more frequent the TAU, and the fewer base stations participate in paging, which is more beneficial to network power consumption. However, it increases the number of TAU executions.

[0003] Therefore, the prior art cannot reduce the number of TAU, optimize the paging operation, and thus reduce the power consumption of the terminal device. Summary of the Invention

[0004] This application provides a paging optimization method and apparatus, which solves the problem that the prior art cannot reduce the number of TAU, optimize the paging operation, and thus reduce the power consumption of the terminal device.

[0005] In a first aspect, this application provides a paging optimization method applied to a terminal device. The method includes:

[0006] Determine a first identifier; the first identifier is the identifier of the sensing module or a second identifier, and the second identifier is the identifier used to page the terminal device;

[0007] Send the first identifier.

[0008] In an embodiment of this application, if the sensing module of the terminal device has its own identifier, the first identifier here can be the identifier of the sensing module. If the sensing module of the terminal device does not have its own identifier or the sensing module does not feedback its identifier, the first identifier here can be the identifier used to page the terminal device, and no specific limitation is made here. The terminal device feeds back the identifier of the sensing module of the terminal device or the second identifier used to page the terminal device to the network through the sensing process, realizes sensing-based paging, does not need to execute TAU or reduces the number of TAU, optimizes the paging process, and thus reduces the UE power consumption.

[0009] Optionally, the sending of the first identifier includes any one of the following:

[0010] Determine that the terminal device has performed cell reselection, and send the first identifier;

[0011] Determine that the terminal device has not performed cell reselection, but meets the first preset condition, and send the first identifier;

[0012] Receive a sensing request, and send the first identifier.

[0013] In the embodiments of the present application, the terminal device can determine whether to send the first identifier in different ways: Way 1: If it is determined that the terminal device has performed cell reselection, that is, the terminal device has undergone cell reselection, send the first identifier; Way 2: If it is determined that the terminal device has not performed cell reselection, that is, the terminal device has not undergone cell reselection, but meets the first preset condition (for example, when the residence time of the terminal device in the current cell exceeds the first time threshold), send the first identifier; Way 3: If the terminal device receives a sensing request, send the first identifier. The diversification or multiple feasibilities of the operation of executing the sending of the first identifier are realized.

[0014] Optionally, the method further includes:

[0015] Determine that the location update operation is no longer to be performed; or,

[0016] Determine to reduce the frequency of performing the location update operation.

[0017] Optionally, the determination that the location update operation is no longer to be performed includes:

[0018] Receive a first paging message, where the first paging message is used to indicate that the terminal device no longer performs the location update operation.

[0019] Optionally, the first paging message is specifically used to indicate that the terminal device no longer performs the location update operation within a specified first time period.

[0020] Optionally, the method further includes:

[0021] Receive a second paging message, where the second paging message is used to indicate that if the terminal device does not receive an indication indicating that the terminal device no longer performs the location update operation within a specified second time period, the terminal device needs to or is allowed to perform the location update operation.

[0022] Optionally, the determination to reduce the frequency of performing the location update operation includes:

[0023] Receive a third paging message, where the third paging message is used to indicate any one of the following:

[0024] After receiving the third paging message, the terminal device performs the location update operation;

[0025] After the terminal device determines that the second preset condition is satisfied, it performs an area update operation;

[0026] After the terminal device determines that the area update operation has not been performed N times, it performs an area update operation.

[0027] In the embodiments of the present application, the terminal device can determine based on the indication in the received paging message that it no longer performs the area update operation or reduces the frequency of performing the area update operation, and can also determine under what specific conditions or scenarios it no longer performs the area update operation, can or needs to perform the area update operation, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0028] Optionally, the method further includes:

[0029] Sending a first message, where the first message is used to indicate that the terminal device supports paging optimization operations.

[0030] In the embodiments of the present application, if the terminal device supports paging optimization operations, it can send a message carrying indication information that the terminal device supports paging optimization operations to a network device (such as an access network device or a core network device). Only when the terminal device supports the above operations, will the network device send a sensing request to the terminal device, and the access network device will save and / or inform the core network device of the first identifier. It can be realized that if the terminal device supports paging optimization operations, it can use the sensing process for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs a TAU, thereby reducing the power consumption of the terminal device.

[0031] Optionally, the first identifier is the radio frequency fingerprint of the communication module of the terminal device or the radio frequency fingerprint of the sensing module of the terminal device;

[0032] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0033] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is obtained by the access network device through the communication module or extracted from the information fed back by the sensing module.

[0034] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as the identifier of the sensing module and / or communication module of the terminal device. By identifying the radio frequency fingerprint, the unique device can be determined to ensure the accuracy of paging.

[0035] Optionally, the method further includes:

[0036] Associate the first identifier with the second identifier to determine the corresponding relationship between the first identifier and the second identifier.

[0037] Optionally, the associating the first identifier with the second identifier includes:

[0038] Receive a second message through the communication module of the terminal device, where the second message is used to indicate that the time-frequency resource of the first identifier is sent through the sensing module of the terminal device and the time-frequency resource is only used by the terminal device;

[0039] According to the second message, send the first identifier on the time-frequency resource through the sensing module of the terminal device, and bind the first identifier to the identifier used for paging the terminal device.

[0040] In the embodiments of the present application, the terminal device can associate the first identifier and the second identifier, and send the corresponding relationship between the first identifier and the second identifier to the network device in a secure manner. During subsequent use, the network device can determine the second identifier based on the first identifier, implement paging the corresponding terminal device by obtaining the second identifier through sensing, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0041] Optionally, the method further includes:

[0042] Indicate the sensing request signal of the cell where the terminal device camps through the communication module of the terminal device to the sensing module of the terminal device; and / or,

[0043] Respond to the sensing request signal indicated by the communication module of the terminal device through the sensing module of the terminal device.

[0044] In the embodiments of the present application, since the sensing module of the terminal device may respond to the sensing requests of multiple cells, in order to prevent the terminal device from feeding back the first identifier to multiple cells and making multiple cells think that the terminal device camps under them, the communication module of the terminal device can inform the sensing module of the terminal device of the sensing request signal of the cell where the terminal device camps, so that the sensing module only needs to respond to the sensing request signal informed by the communication module, saving paging resources.

[0045] Optionally, the method further includes:

[0046] Receive a fourth paging message, where the fourth paging message is used to indicate that the terminal device accesses the access network device, and the first identifier of the terminal device is included in the fourth paging message;

[0047] Access the access network device according to the first identifier.

[0048] In an embodiment of the present application, the access of the terminal device to the access network device may be that the terminal device establishes a connection with the access network device, or the terminal device accesses the cell corresponding to the access network device. The first identifier here is the identifier used to page the terminal device. When the terminal device receives a paging message carrying the first identifier, it can directly notify the communication module of the terminal device to access the access network device based on the first identifier, thereby avoiding or reducing the number of TAUs performed by the terminal device based on sensing, and thus reducing the power consumption of the terminal device.

[0049] Optionally, the method further includes:

[0050] Determining a manner of performing paging optimization operations;

[0051] Sending a third message, where the third message is used to indicate the manner of performing paging optimization operations by the terminal device;

[0052] Wherein, the manner of performing paging optimization operations includes the steps performed by the method described in any one of the above.

[0053] In an embodiment of the present application, for the terminal device to adopt an optimized TAU process (here referring to the steps of any one of the above paging optimization methods), both the terminal device and the network (here referring to network devices, access network devices, and / or core network devices) need to know. This can avoid the following situations: If the terminal device does not know and continues to perform the TAU process, the number of TAUs performed by the terminal device cannot be avoided or reduced; if the network does not know and the terminal device adopts the above TAU optimization process, reducing the TAU reporting, and the network does not receive the TAU process of the terminal device at the expected TAU moment, the network may consider the terminal device to be abnormal, thus leading to situations such as paging anomalies.

[0054] In a second aspect, the present application provides a paging optimization method applied to an access network device. The method includes:

[0055] Receiving a first identifier sent by a terminal device, where the first identifier is an identifier of a sensing module or a second identifier, and the second identifier is an identifier used to page the terminal device;

[0056] Sending the first identifier to a core network device.

[0057] In an embodiment of the present application, an access network device (e.g., a base station) sends the first identifier, i.e., the identifier of the sensing module or the second identifier for paging the terminal device, received from the terminal device, to the core network device, and obtains the identifier of the sensing module of the terminal device under a cell or the second identifier for paging the terminal device through a sensing process, so as to implement sensing-based paging, without performing a TAU or reducing the number of TAUs, optimize the paging process, and thus reduce the power consumption of the terminal device.

[0058] Optionally, one access network device corresponds to at least one cell; the method further includes:

[0059] Sending the information of the access network device to the core network device; and / or,

[0060] Sending the cell information where the terminal device resides to the core network device, where the cell information includes the identifier of the cell.

[0065] Periodically sending the first identifier of the terminal device entering and / or exiting the access network device stored to the core network device; and / or,

[0066] Sending the first identifier of the terminal device newly entering the access network device to the core network device.

[0067] In an embodiment of the present application, the access network device can continuously send sensing requests to sense the terminal devices entering and exiting thereunder, especially the entering terminal devices. If a newly entered terminal device is sensed, it can send its own information and the information of the terminal device (e.g., the first identifier of the terminal device, the cell identifier where the terminal device resides, etc.) to the core network device, or send it to the core network device periodically. The core network device updates its database. When paging the corresponding terminal subsequently, it preferentially pages the terminal device under the cell (the cell corresponding to the cell identifier where the terminal device resides reported by the access network device in the above process), improving the accuracy of paging success and saving paging resources.

[0068] Optionally, the method further includes:

[0069] Periodically delete the first identifier of the terminal device that has exited the access network device from storage.

[0070] Among them, the exit from the access network device may be to exit all cells corresponding to the access network device or no longer camp on any cell corresponding to the access network device.

[0071] In the embodiments of the present application, in order to save storage resources, the first identifier of the terminal device that has exited the access network device can be periodically deleted to achieve storage update.

[0072] Optionally, the method further includes:

[0073] Send a sensing request to the terminal device.

[0074] Optionally, adjacent cells correspond to different sensing requests.

[0075] In the embodiments of the present application, based on the fact that adjacent cells correspond to different sensing requests, after the access network device sends a sensing request to the terminal device, the terminal device can determine which cell's sensing request it is based on the sensing request signal, avoiding the terminal device from sending the first identifier to multiple cells and making multiple cells think that the terminal device is camping under them.

[0076] Optionally, the method further includes:

[0077] Send a first paging message to the terminal device, where the first paging message is used to indicate that the terminal device no longer performs a location update operation.

[0079] Optionally, the method further includes:

[0080] Send a second paging message to the terminal device, where the second paging message is used to indicate that if the terminal device does not receive an indication from the access network device indicating that the terminal device no longer performs a location update operation within a specified second time period, the terminal device needs to or is allowed to perform a location update operation.

[0081] Optionally, the method further includes:

[0082] Send a third paging message to the terminal device, where the third paging message is used to indicate any of the following:

[0083] After receiving the third paging message, the terminal device performs a location update operation;

[0084] After the terminal device determines that the second preset condition is met, it performs a region update operation;

[0085] After the terminal device determines that the region update operation has not been performed N times, it performs a region update operation.

[0086] In the embodiments of the present application, the access network device can send a paging message to the terminal device, instructing the terminal device to no longer perform the region update operation or reduce the frequency of performing the region update operation, and can also specifically indicate under what conditions or scenarios the region update operation is no longer performed, can be or needs to be performed, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0087] Optionally, the method further includes:

[0088] Receiving a first message, where the first message is used to indicate whether the terminal device supports paging optimization operations.

[0089] In the embodiments of the present application, if the terminal device supports paging optimization operations, it can send a message carrying the indication information that the terminal device supports paging optimization operations to a network device (such as an access network device or a core network device). Only when the terminal device supports the above operations, after receiving this message, the access network device will send a sensing request to the terminal device, will save and / or inform the core network device of the first identifier. After receiving this message, the core network device will receive the identifier and cell identifier used for paging the terminal device obtained based on sensing, and perform paging according to the identifier and cell identifier used for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, the sensing process can be used for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, thereby reducing the power consumption of the terminal device.

[0090] Optionally, the first identifier is the radio frequency fingerprint of the communication module in the terminal device or the radio frequency fingerprint of the sensing module in the terminal device;

[0091] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0092] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is obtained by the access network device through the communication module or extracted from the information fed back by the sensing module.

[0093] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as the identifier of the sensing module and / or communication module of the terminal device. By identifying the radio frequency fingerprint, the unique device can be determined to ensure the accuracy of paging.

[0094] Optionally, the method further comprises:

[0095] A second message is sent, where the second message is used to indicate whether the access network device supports paging optimization operations.

[0096] In an embodiment of the present application, the access network device can send a message to the terminal device or the core network device that it supports the paging optimization operation. Only when the access network device supports the above operation, the terminal device will send the first identifier to the access network device, and the core network device will receive the identifier and cell identifier used for paging the terminal device based on the perception of the access network device, and perform paging based on the identifier and cell identifier used for paging the terminal device, thereby optimizing the paging operation and reducing the power consumption of the terminal device.

[0097] Optionally, the method further comprises:

[0098] Associating the first identifier with the second identifier to determine a corresponding relationship between the first identifier and the second identifier; or,

[0102] Binding is performed according to the first identifier and the identifier used for paging the terminal device.

[0103] In an embodiment of the present application, the access network device can associate the first identifier and the second identifier, and send the correspondence between the first identifier and the second identifier to the core network device in a secure manner, or receive the correspondence between the first identifier and the second identifier sent by the terminal device or the core network device. In the subsequent use process, the network device can determine the second identifier based on the first identifier, and implement paging of the corresponding terminal device based on the perception of the second identifier, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0104] Optionally, the method further comprises:

[0105] According to the signal strength of the received perception response sent by the terminal device, it is determined whether the terminal device resides in the cell under the access network device.

[0106] In an embodiment of the present application, since the perception module of the terminal device may respond to perception requests of multiple cells, in order to more accurately determine whether the terminal device resides in a cell under the access network device, it can be determined based on the signal strength of the perception response sent by the terminal device. If the signal strength is strong or reaches a certain threshold, it can be determined that the terminal device resides in a cell under the access network device.

[0107] Optionally, the method further comprises:

If the access network device receives the first identifier sent by the core network device, it can send a paging message carrying the first identifier to the terminal device. When the terminal device receives the paging message carrying the first identifier, it can directly notify the communication module of the terminal device based on the first identifier to access the access network device, thereby realizing perception-based paging to avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0113] The paging optimization operation method includes steps performed by any of the methods described above.

[0114] In an embodiment of the present application, the terminal device adopts an optimized TAU process (here refers to the steps of any of the above-mentioned paging optimization methods), which requires the network (here refers to the network device) to know. This can avoid the situation where the network is unaware and the terminal device adopts the above-mentioned TAU optimization process, reducing TAU reports. The network does not receive the TAU process of the terminal device at the expected TAU time. The network may believe that there is an abnormality in the terminal device, which in turn leads to paging abnormalities and other situations.

[0115] In a third aspect, the present application provides a paging optimization method, applied to a core network device, the method comprising:

Therefore, the second identifier of the terminal device under a cell and the corresponding cell information are obtained through the sensing process. During subsequent paging, the terminal device can be preferentially paged in the cell corresponding to the updated cell information, realizing paging based on sensing, without performing TAU or reducing the number of TAUs, optimizing the paging process, and thus reducing the power consumption of the UE.

Only when the terminal device supports the above operations will the network device send a sensing request to the terminal device, and only then will the access network device save and / or inform the core network device of the first identifier. After receiving the message, the core network device will receive the identifier and cell identifier for paging the terminal device obtained based on sensing and perform paging according to the identifier and cell identifier for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, sensing can be used for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, and thus reducing the power consumption of the terminal device.

[0132] Optionally, the first identifier is the radio frequency fingerprint of the communication module in the terminal device or the radio frequency fingerprint of the sensing module in the terminal device;

[0135] In an embodiment of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint may be used as the identifier of the sensing module and / or the communication module of the terminal device. By identifying the radio frequency fingerprint, a unique device can be determined to ensure the accuracy of paging.

[0138] In the embodiments of the present application, if the core network device supports paging optimization operations, it can send a message carrying indication information of supporting paging optimization operations to the terminal device or the access network device. Only when the core network supports the above operations, the core network device will receive the first identifier determined based on sensing and the corresponding cell information, and then determine the second identifier and the corresponding cell for paging the terminal device. In subsequent paging, when sending a paging message to the access network device, the corresponding terminal device can be paged.

[0162] After receiving the third paging message, the terminal device performs a location update operation;

[0163] After the terminal device determines that a second preset condition is met, the terminal device performs a location update operation;

[0164] After the terminal device determines that it has not performed a location update operation N times, the terminal device performs a location update operation.

[0165] In an embodiment of the present application, the terminal device can determine based on the indication in the received paging message that it no longer performs a location update operation or reduces the frequency of performing a location update operation, and can also determine under what specific conditions or scenarios it no longer performs a location update operation, can or needs to perform a location update operation, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0166] Optionally, the sending unit is further configured to:

[0167] Send a first message, where the first message is used to indicate that the terminal device supports paging optimization operations.

[0168] In an embodiment of the present application, if the terminal device supports paging optimization operations, it can send a message carrying indication information that the terminal device supports paging optimization operations to a network device (for example, an access network device or a core network device). Only when the terminal device supports the above operations, the network device will send a sensing request to the terminal device, and the access network device will save and / or inform the core network device of the first identifier. It can be realized that if the terminal device supports paging optimization operations, it can use the sensing process for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs a TAU, thereby reducing the power consumption of the terminal device.

[0169] Optionally, the first identifier is the radio frequency fingerprint of the communication module of the terminal device or the radio frequency fingerprint of the sensing module of the terminal device;

[0170] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0171] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is obtained by the access network device through the communication module or extracted from the information fed back by the sensing module.

[0172] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as an identifier of the sensing module and / or the communication module of the terminal device. By identifying the radio frequency fingerprint, a unique device can be determined to ensure the accuracy of paging.

[0173] Optionally, the device further includes: a processing unit; the processing unit is configured to:

[0174] Associate the first identifier with the second identifier to determine the correspondence between the first identifier and the second identifier.

[0175] Optionally, the processing unit is specifically configured to:

[0177] According to the second message, send the first identifier on the time-frequency resource through the sensing module of the terminal device, and bind the first identifier to the identifier used for paging the terminal device.

[0178] In the embodiments of the present application, the terminal device can associate the first identifier and the second identifier, and send the correspondence between the first identifier and the second identifier to the network device in a secure manner. In the subsequent usage process, the network device can determine the second identifier based on the first identifier, implement paging the corresponding terminal device by obtaining the second identifier based on sensing, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0181] Respond to the sensing request signal indicated by the communication module of the terminal device through the sensing module of the terminal device.

[0182] In the embodiments of the present application, since the sensing module of the terminal device may respond to sensing requests of multiple cells, in order to prevent the terminal device from feeding back the first identifier to multiple cells and making multiple cells think that the terminal device is camping under them, the communication module of the terminal device can inform the sensing module of the terminal device of the sensing request signals of the cells where the terminal device is camping. In this way, the sensing module only needs to respond to the sensing request signals informed by the communication module, saving paging resources.

[0183] Optionally, the processing unit is further configured to: receive fourth paging information, where the fourth paging message is used to instruct the terminal device to access an access network device, and the fourth paging message includes the first identifier of the terminal device;

[0184] The processing unit is further configured to: access the access network device according to the first identifier.

[0185] In the embodiments of the present application, the access of the terminal device to the access network device may be that the terminal device establishes a connection with the access network device, or the terminal device accesses the cell corresponding to the access network device. Here, the first identifier is the identifier used to page the terminal device. When the terminal device receives a paging message carrying the first identifier, it can directly notify the communication module of the terminal device based on the first identifier to access the access network device, realizing paging based on sensing to avoid or reduce the number of TAUs of the terminal device, thereby reducing the power consumption of the terminal device.

[0189] In the embodiments of the present application, for the terminal device to adopt an optimized TAU process (here referring to the steps of any one of the above paging optimization methods), both the terminal device and the network (here referring to network devices, access network devices, and / or core network devices) need to know. This can avoid the following situations: If the terminal device does not know and continues to perform the TAU process, the number of TAUs of the terminal device cannot be avoided or reduced; If the network does not know and the terminal device adopts the above TAU optimization process, reducing the TAU reporting, and the network does not receive the TAU process of the terminal device at the expected TAU moment, the network may think that the terminal device is abnormal, which may lead to paging anomalies and other situations.

[0203] In the embodiments of the present application, the access network device can continuously send sensing requests to sense the terminal devices coming in and out under it, especially the incoming terminal devices. If a newly entered terminal device is sensed, the access network device can send its own information and the information of the terminal device (such as the first identifier of the terminal device, the cell identifier where the terminal device resides, etc.) to the core network device, or send it to the core network device periodically. The core network device updates its database. When paging the corresponding terminal later, it preferentially pages the terminal device in this cell (the cell corresponding to the cell identifier where the terminal device resides reported by the access network device in the above process), improving the accuracy of paging success and saving paging resources.

[0204] Optionally, the apparatus further includes: a processing unit; the processing unit is configured to:

[0205] Periodically delete the first identifiers of the terminal devices that have exited the access network device stored.

[0206] In the embodiments of the present application, the first identifiers of the terminal devices that have exited the access network device are deleted. Wherein, the terminal devices that have exited the access network device may refer to that the terminal devices have exited all the cells corresponding to the access network device or the terminal devices no longer reside in any cell corresponding to the access network. In order to save storage resources, the first identifiers of the terminal devices that have exited the access network device can be deleted periodically to achieve storage update.

[0219] After the terminal device determines that a second preset condition is satisfied, the terminal device performs a location update operation;

[0220] After the terminal device determines that it has not performed a location update operation N times, the terminal device performs a location update operation.

[0221] In the embodiments of the present application, the access network device may send a paging message to the terminal device to indicate that the terminal device no longer performs a location update operation or reduces the frequency of performing a location update operation, and may also specifically indicate under what conditions or scenarios the location update operation is no longer performed, can be or needs to be performed, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0224] In the embodiments of the present application, if the terminal device supports paging optimization operations, it may send a message carrying indication information that the terminal device supports paging optimization operations to a network device (for example, an access network device or a core network device). Only when the terminal device supports the above operations, after receiving this message, the access network device will send a sensing request to the terminal device, will keep or inform the core network device of the first identifier, and after receiving this message, the core network device will receive the identifier and cell identifier used for paging the terminal device obtained based on sensing, and perform paging according to the identifier and cell identifier used for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, sensing can be used for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs a TAU, thereby reducing the power consumption of the terminal device.

[0225] Optionally, the first identifier is the radio frequency fingerprint of the communication module in the terminal device or the radio frequency fingerprint of the sensing module in the terminal device;

[0228] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as the identifier of the sensing module and / or the communication module of the terminal device. By identifying the radio frequency fingerprint, a unique device can be determined to ensure the accuracy of paging.

[0229] Optionally, the sending unit is further configured to:

[0238] Optionally, the processing unit is further configured to:

[0239] According to the signal strength of the received perception response sent by the terminal device, it is determined whether the terminal device resides in the cell under the access network device.

[0240] In an embodiment of the present application, since the perception module of the terminal device may respond to perception requests of multiple cells, in order to more accurately determine whether the terminal device resides in a cell under the access network device, it can be determined based on the signal strength of the perception response sent by the terminal device. If the signal strength is strong or reaches a certain threshold, it can be determined that the terminal device resides in a cell under the access network device.

[0243] In an embodiment of the present application, the first identifier here is an identifier used for paging a terminal device. If the access network device receives the first identifier sent by the core network device, it can send a paging message carrying the first identifier to the terminal device. When the terminal device receives the paging message carrying the first identifier, it can directly notify the communication module of the terminal device based on the first identifier to access the access network device, thereby realizing perception-based paging to avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0247] In the embodiments of the present application, when the terminal device adopts an optimized TAU process (here referring to the steps of any of the above paging optimization methods), the network (here referring to the network device) needs to know. This can avoid the situation that if the network does not know and the terminal device adopts the above TAU optimization process, resulting in a reduction in TAU reporting. At the expected TAU moment, the network does not receive the TAU process of the terminal device, and the network may consider that the terminal device is abnormal, thus leading to abnormal paging and other situations.

[0314] In an embodiment of the present application, since the perception module of the terminal device may respond to perception requests of multiple cells, in order to avoid the terminal device from feeding back the first identifier to multiple cells so that multiple cells believe that the terminal device is residing therein, the communication module of the terminal device can be informed of the perception module of the terminal device of the perception request signal of the cell where the terminal device is residing. In this way, the perception module only needs to respond to the perception request signal informed by the communication module, thereby saving paging resources.

[0315] Optionally, the processor is further configured to perform the following operations:

[0316] receiving a fourth paging message, where the fourth paging message is used to instruct the terminal device to access the access network device, and the fourth paging message includes a first identifier of the terminal device;

[0317] Access the access network device according to the first identifier.

[0318] In the embodiment of the present application, the terminal device accessing the access network device may be that the terminal device establishes a connection with the access network device, or the terminal device accesses the cell corresponding to the access network device. The first identifier here is an identifier used for paging the terminal device. If the terminal device receives a paging message carrying the first identifier, the communication module of the terminal device can be directly notified based on the first identifier to access the access network device, thereby realizing perception-based paging to avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0319] Optionally, the processor is further configured to perform the following operations:

[0320] Determine the method of using paging optimization operation;

[0321] Send a third message, where the third message is used to indicate the manner in which the terminal device adopts paging optimization operations;

[0322] Wherein, the manner of the paging optimization operation includes the steps performed by the method described in any of the above items.

[0323] In the embodiments of the present application, for the terminal device to adopt an optimized TAU process (here referring to the steps of any of the above paging optimization methods), both the terminal device and the network (here referring to network devices, access network devices, and / or core network devices) need to know. This can avoid the following situations: If the terminal device does not know and continues to execute the TAU process, it is impossible to avoid or reduce the number of TAU operations of the terminal device; if the network does not know and the terminal device adopts the above TAU optimization process, reducing the TAU reporting, and the network does not receive the TAU process of the terminal device at the expected TAU moment, the network may consider the terminal device to be abnormal, thereby leading to situations such as paging anomalies.

[0324] In an eighth aspect, the present application provides a paging optimization device applied to an access network device. The device includes a memory, a transceiver, and a processor:

[0325] The memory is used to store computer programs; the transceiver is used to transmit and receive data under the control of the processor; the processor is used to read the computer programs in the memory and perform the following operations:

[0326] Receive a first identifier sent by a terminal device, where the first identifier is an identifier of a sensing module or a second identifier, and the second identifier is an identifier used for paging the terminal device;

[0327] Send the first identifier to a core network device.

[0328] In the embodiments of the present application, the access network device (such as a base station) receives the first identifier sent by the terminal device, that is, the identifier of the sensing module or the second identifier used for paging the terminal device, and sends the first identifier to the core network device. By obtaining the identifier of the sensing module of the terminal device in a cell or the second identifier used for paging the terminal device through the sensing process, paging based on sensing is achieved, without the need to execute TAU or reducing the number of TAU operations, optimizing the paging process, and thus reducing the power consumption of the terminal device.

[0329] Optionally, one access network device corresponds to at least one cell; the processor is further used to perform the following operations:

[0330] Send the information of the access network device to the core network device; and / or,

[0332] Optionally, the processor is further configured to perform the following operations:

[0333] Store the first identifier of the terminal device entering and / or exiting the access network device.

[0334] Wherein, the entering the access network device may be entering or camping on at least one cell corresponding to the access network device.

[0335] Optionally, when sending the first identifier to the core network device, the processor specifically includes:

[0336] Periodically send the stored first identifier of the terminal device entering and / or exiting the access network device to the core network device; and / or,

[0337] Send the first identifier of the terminal device newly entering the access network device to the core network device.

[0338] In the embodiments of the present application, the access network device can sense the terminal devices entering and exiting under it by continuously sending sensing requests, especially the entering terminal devices. If a newly entered terminal device is sensed, it can send its own information and the information of the terminal device (such as the first identifier of the terminal device, the cell identifier where the terminal device camps, etc.) to the core network device, or send it to the core network device periodically. The core network device updates its database. When paging the corresponding terminal subsequently, it preferentially pages the terminal device in this cell (the cell corresponding to the cell identifier where the terminal device reported by the access network device camps in the above process), improving the accuracy of paging success and saving paging resources.

[0339] Optionally, the processor is further configured to perform the following operations:

[0340] Periodically delete the stored first identifier of the terminal device exiting the access network device.

[0341] In the embodiments of the present application, delete the first identifier of the terminal device exiting the access network device. Wherein, the terminal device exiting the access network device may refer to the terminal device exiting all cells corresponding to the access network device or the terminal device no longer camping on any cell corresponding to the access network. In order to save storage resources, the first identifier of the terminal device exiting the access network device can be periodically deleted to achieve storage update.

[0342] Optionally, the processor is further configured to perform the following operations:

[0343] Send a sensing request to the terminal device.

[0344] Optionally, adjacent cells correspond to different sensing requests.

[0345] In the embodiments of the present application, based on the fact that adjacent cells correspond to different sensing requests, after the access network device sends a sensing request to the terminal device, the terminal device can determine which cell's sensing request it is based on the sensing request signal, avoiding the terminal device from feeding back the first identifier to multiple cells and making multiple cells think that the terminal device is camping under them.

[0346] Optionally, the processor is further configured to perform the following operations:

[0349] Optionally, the processor is further configured to perform the following operations:

[0350] Send a second paging message to the terminal device, where the second paging message is used to indicate that if the terminal device does not receive an indication from the access network device indicating that the terminal device no longer performs a location update operation within a specified second time period, the terminal device needs to or is allowed to perform a location update operation.

[0351] Optionally, the processor is further configured to perform the following operations:

[0353] After receiving the third paging message, the terminal device performs a location update operation;

[0354] After the terminal device determines that a second preset condition is satisfied, the terminal device performs a location update operation;

[0355] After the terminal device determines that it has not performed a location update operation N times, the terminal device performs a location update operation.

[0356] In the embodiments of the present application, the access network device can send a paging message to the terminal device to indicate that the terminal device no longer performs a location update operation or reduces the frequency of performing a location update operation, and can also specifically indicate under what conditions or scenarios the terminal device no longer performs a location update operation, can or needs to perform a location update operation, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0357] Optionally, the processor is further configured to perform the following operations:

[0358] Receive a first message, where the first message is used to indicate whether the terminal device supports paging optimization operations.

[0359] In the embodiments of the present application, if the terminal device supports paging optimization operations, it may send a message carrying indication information that the terminal device supports paging optimization operations to a network device (for example, an access network device or a core network device). Only when the terminal device supports the above operations, after receiving this message, the access network device will send a sensing request to the terminal device, save and / or inform the core network device of the first identifier. After receiving this message, the core network device will receive the identifier and cell identifier used for paging the terminal device obtained based on sensing, and perform paging according to the identifier and cell identifier used for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, paging can be performed using the sensing process, avoiding or reducing the number of times the terminal device (such as a UE) performs a TAU, thereby reducing the power consumption of the terminal device.

[0360] Optionally, the first identifier is the radio frequency fingerprint of the communication module in the terminal device or the radio frequency fingerprint of the sensing module in the terminal device;

[0361] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0362] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is extracted from the information fed back by the access network device through the communication module or the sensing module.

[0363] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as the identifier of the sensing module and / or communication module of the terminal device. By identifying the radio frequency fingerprint, the unique device can be determined to ensure the accuracy of paging.

[0364] Optionally, the processor is further configured to perform the following operations:

[0366] In an embodiment of the present application, the access network device can send a message to the terminal device or the core network device that it supports the paging optimization operation. Only when the access network device supports the above operation, the terminal device will send the first identifier to the access network device, and the core network device will receive the identifier and cell identifier used for paging the terminal device based on the perception of the access network device, and perform paging based on the identifier and cell identifier used for paging the terminal device, thereby optimizing the paging operation and reducing the power consumption of the terminal device.

[0370] Optionally, the processor is configured to, when associating the first identifier with the second identifier, specifically include:

[0371] Sending a third message to the perception module of the terminal device through the communication module of the terminal device, wherein the third message is used to instruct the terminal device to send the time-frequency resource of the first identifier through the perception module of the terminal device and the time-frequency resource is only used by the terminal device;

[0372] Binding is performed according to the first identifier and the identifier used for paging the terminal device.

[0373] In an embodiment of the present application, the access network device can associate the first identifier and the second identifier, and send the correspondence between the first identifier and the second identifier to the core network device in a secure manner, or receive the correspondence between the first identifier and the second identifier sent by the terminal device or the core network device. In the subsequent use process, the network device can determine the second identifier based on the first identifier, and implement paging of the corresponding terminal device based on the perception of the second identifier, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0374] Optionally, the processor is further configured to perform the following operations:

[0375] According to the signal strength of the received perception response sent by the terminal device, it is determined whether the terminal device resides in the cell under the access network device.

[0376] In the embodiments of the present application, since the sensing module of the terminal device may respond to sensing requests of multiple cells, in order to accurately determine whether the terminal device is resident in the cell under the access network device, it can be determined based on the signal strength of the sensing response sent by the terminal device. If the signal strength is strong or reaches a certain threshold, it can be determined that the terminal device is resident in a certain cell under the access network device.

[0377] Optionally, the processor is further configured to perform the following operations:

[0380] In the embodiments of the present application, the first identifier here is the identifier used to page the terminal device. If the access network device receives the first identifier sent by the core network device, it can send a paging message carrying the first identifier to the terminal device. When the terminal device receives the paging message carrying the first identifier, it can directly notify the communication module of the terminal device to access the access network device based on the first identifier, which realizes paging based on sensing to avoid or reduce the number of TAUs of the terminal device, thereby reducing the power consumption of the terminal device.

[0384] In the embodiments of the present application, for the terminal device to adopt an optimized TAU process (here referring to the steps of any of the above paging optimization methods), the network (here referring to the network device) needs to know. This can avoid situations where if the network doesn't know and the terminal device adopts the above TAU optimization process, reducing the TAU reporting, and at the expected TAU moment, the network doesn't receive the TAU process of the terminal device, and the network may consider the terminal device to be abnormal, which may lead to paging anomalies and other situations.

Therefore, the second identifier of the terminal device under a cell and the corresponding cell information are obtained through the sensing process. When paging subsequently, the terminal device can be preferentially paged in the cell corresponding to the updated cell information, realizing paging based on sensing, without performing TAU or reducing the number of TAU times, optimizing the paging process, and thus reducing the power consumption of the UE.

[0390] Optionally, the processor is further configured to perform the following operations:

[0399] In the embodiments of the present application, the core network device may associate the first identifier and the second identifier, and send the corresponding relationship between the first identifier and the second identifier to the access network device or the terminal device in a secure manner. Alternatively, the core network device may receive the corresponding relationship between the first identifier and the second identifier sent by the terminal device or the access network device. During subsequent use, the core network device may determine the second identifier based on the first identifier, so as to implement paging the corresponding terminal device by obtaining or determining the second identifier based on sensing, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, and thus reduce the power consumption of the terminal device.

[0400] Optionally, the processor is further configured to perform the following operations:

[0402] In the embodiments of the present application, if the terminal device supports paging optimization operations, the terminal device may send a message carrying indication information that the terminal device supports paging optimization operations to a network device (such as an access network device or a core network device). Only when the terminal device supports the above operations, the network device will send a sensing request to the terminal device, and the access network device will save and / or inform the core network device of the first identifier. After receiving the message, the core network device will receive the identifier and the cell identifier for paging the terminal device obtained based on sensing, and perform paging according to the identifier and the cell identifier for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, the sensing process can be used for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, and thus reducing the power consumption of the terminal device.

[0406] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint may be used as the identifier of the sensing module and / or the communication module of the terminal device. By identifying the radio frequency fingerprint, the unique device can be determined to ensure the accuracy of paging.

[0407] Optionally, the processor is further configured to perform the following operations:

[0409] In the embodiments of the present application, if the core network device supports paging optimization operations, it can send a message carrying indication information of supporting paging optimization operations to the terminal device or the access network device. Only when the core network supports the above operations, the core network device will receive the first identifier determined based on sensing and the corresponding cell information, and then determine the second identifier and the corresponding cell for paging the terminal device. In subsequent paging, a paging message is sent to the access network device, and the corresponding terminal device can be paged. If the core network device supports paging optimization operations, it can use the sensing process for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, thereby reducing the power consumption of the terminal device.

[0410] Optionally, the processor is further configured to perform the following operations:

[0439] In the embodiments of the present application, the term "and / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0440] In the embodiments of the present application, the term "plurality" refers to two or more, and other quantifiers are similar.

[0441] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0442] To clearly understand the technical solutions of the present application, the solutions of the prior art will be introduced in detail first.

[0443] The integration of communication and sensing is an important research direction for 6G: The goal is to use wireless sensing technologies such as radar and imaging to achieve the sensing of the position, posture, and environmental information of objects such as non-target terminals, so as to obtain multi-dimensional and multi-level sensing data, expand the connection range of the mobile communication system from target terminals to things and the environment, and truly realize the intelligent connection of all things. Through the deep integration of wireless communication and wireless sensing, the 6G system will further enhance its service capabilities as a new type of infrastructure, so as to better meet the needs of all aspects such as personal life, vertical industries, and social governance. An important goal of the integration of communication and sensing is to use sensing to assist communication, that is, to optimize the communication process using the information obtained through sensing. For example, by using the sensed environment to adjust transmission and reception, mobility and beamforming can be improved. Because sensing can achieve capabilities such as high-precision positioning, imaging, and environmental reconstruction, the channel information can be more accurately grasped, and the communication performance can be improved. For example, the accuracy of beamforming can be improved, the speed of beam failure recovery can be accelerated, and the overhead of tracking channel state information can be reduced.

[0444] However, in the cross-sensory fusion network, for the paging process in the prior art, in the TA and tracking area update mechanisms defined in the existing protocol, when performing the TAU process, the terminal device needs to establish an RRC connection and send an uplink message, which is power-consuming for the terminal device. Moreover, the frequency of TAU is related to the size of the TA and the moving speed of the terminal device. The larger the TA, the smaller the frequency of TAU. However, the more base stations participate in paging, the greater the network power consumption. On the contrary, the smaller the TA, the more frequent the TAU, and the fewer base stations participate in paging, which is more beneficial for network power consumption. However, it increases the number of times of performing TAU. Therefore, in the cross-sensory fusion network of the prior art, it is impossible to reduce the number of TAU times, optimize the paging operation, and thus reduce the power consumption of the terminal device.

[0445] To solve the problem of being unable to reduce the number of TAU times, optimize the paging operation, and thus reduce the power consumption of the terminal device, in the cross-sensory fusion network, the information obtained by sensing can be used to reduce the number of TAU times, optimize the paging process, and thus reduce the UE power consumption.

[0446] Therefore, based on the above research, the paging optimization method and device proposed in this application are proposed. In this application, the terminal device can support a sensing module and a communication module. If the sensing module of the terminal device has its own identifier, it can send the identifier of the sensing module of the terminal device. Subsequently, based on the identifier of the sensing module, a second identifier used to page the terminal device is determined. If the sensing module of the terminal device does not have its own identifier or the sensing module does not feedback its identifier, it can send the second identifier used to page the terminal device. In this way, by obtaining the identifier of the sensing module of the terminal device in a cell or the second identifier used to page the terminal device through the sensing process, paging based on sensing can be realized, without performing TAU or reducing the number of TAU times, optimizing the paging process, and thus reducing the UE power consumption.

[0447] It should be noted that the communication module and the sensing module may be the same module or different modules. For the convenience of description, in this application, from the perspective of functional differentiation, they are divided into a communication module and a sensing module, but it is not limited that the communication module and the sensing module must be two independent modules. Of course, the communication signal and the sensing signal may also be the same signal, not necessarily independent communication signals and independent sensing signals. For the convenience of description, from the perspective of functional differentiation, they are also respectively called communication signals and sensing signals (including, for example, sensing requests and sensing responses).

[0448] Among them, the method and the device are based on the same application concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

[0449] The embodiments of this application will be described below with reference to the accompanying drawings.

[0450] See Figure 1 as shown Figure 1 This is a schematic flowchart of the paging optimization method provided by the embodiment of the present application. The execution subject of the paging optimization method provided by this embodiment is a terminal device, such as: a user equipment (abbreviated as UE in English), etc. The following takes the terminal device as UE as an example to elaborate on the paging optimization method in detail.

[0451] The paging optimization method provided by the embodiment of the present application includes the following steps:

[0452] Step 101: Determine the first identifier.

[0453] Wherein, the first identifier is the identifier of the sensing module or the second identifier, and the second identifier is the identifier used to page the terminal device.

[0454] Obtain the identifier of the sensing module of the UE, and use the identifier of the sensing module as the first identifier; or, use the obtained second identifier used to page the UE as the first identifier.

[0455] The UE here can support a sensing module and a communication module. Among them, the sensing module and the communication module can be the same module or different modules, and no specific limitation is made here. If the sensing module of the UE has its own identifier, the first identifier here can be the identifier of the sensing module or the identifier used to page the terminal device, that is, the second identifier. If the sensing module of the UE has no own identifier, the first identifier is the second identifier.

[0456] Step 102: Send the first identifier.

[0457] The UE can send the identifier of the sensing module or the second identifier to the network (here referring to network devices, such as: access network devices or core network devices). Among them, there is a corresponding relationship between the first identifier and the second identifier. If the sensing module has no own identifier or the sensing module does not feedback its own identifier, the first identifier is also the second identifier, that is, directly feedback the identifier of the UE used in the paging process; if the sensing module has its own identifier and the first identifier is the identifier of the sensing module, the second identifier can be determined based on the corresponding relationship between the first identifier and the second identifier based on the identifier of the sensing module, and then the corresponding UE can be paged.

[0458] Among them, the second identifier may be a globally unique temporary UE identifier in the 5G system (abbreviation in English: 5G Globally Unique Temporary Identifier, 5G-GUTI for short), 5G S-temporary mobile subscription identifier (abbreviation in English: 5G S-Temporary Mobile Subscription Identifier, 5G-S-TMSI for short), 5G temporary mobile subscription identifier in the 5G system (abbreviation in English: 5G Temporary Mobile Subscription Identifier, 5G-TMSI for short), global line identifier (abbreviation in English: Global Line Identifier, GLI for short), global cable identifier (abbreviation in English: Global Cable Identifier, GCI for short), globally unique AMF identifier (abbreviation in English: Globally Unique AMF Identifier, GUAMI for short), international mobile equipment identity (abbreviation in English: International Mobile Equipment Identity, IMEI for short), international mobile equipment identity and software version number (abbreviation in English: International Mobile Equipment Identity Software Version, IMEISV for short), international mobile subscriber identification number (abbreviation in English: International Mobile Subscriber Identification Number, IMSI for short), permanent equipment identifier (abbreviation in English: Permanent Equipment Identifier, PEI for short), subscription permanent identifier (abbreviation in English: Subscription Permanent Identifier, SUPI for short), subscription concealed identifier (abbreviation in English: Subscription Concealed Identifier, SUCI for short).

[0459] In the embodiment of the present application, the terminal device feeds back the identifier of the sensing module of the terminal device or the second identifier used for paging the terminal device to the network through the sensing process, so as to implement paging based on sensing, without performing TAU or reducing the number of TAUs, optimize the paging process, and thus reduce the power consumption of the UE.

[0460] Optionally, the sending of the first identifier includes any one of the following:

[0461] Determine that the terminal device has performed cell reselection, and send the first identifier;

[0462] Determine that the terminal device has not performed cell reselection, but meets the first preset condition, and send the first identifier;

[0463] Receive a sensing request and send the first identifier.

[0464] In the embodiments of the present application, the terminal device can determine whether to send the first identifier in different ways: Method 1: If it is determined that the terminal device has performed cell reselection, that is, the terminal device has undergone cell reselection, send the first identifier; Method 2: If it is determined that the terminal device has not performed cell reselection, that is, the terminal device has not undergone cell reselection, but meets the first preset condition (for example, when the residence time of the terminal device in the current cell exceeds the first time threshold), send the first identifier; Method 3: If the terminal device receives a sensing request, send the first identifier. The operation of sending the first identifier is diversified or has multiple feasibilities.

[0465] Exemplarily, Embodiment 1 (The UE sends the first identifier based on any one of Method 1, Method 2, and Method 3)

[0466] See Figure 2 as shown Figure 2 is an interaction diagram of the paging optimization method provided by the embodiments of the present application Figure 1 . The paging optimization method provided in this embodiment includes the following steps:

[0467] Step 1: The UE determines to send the first identifier.

[0468] For Method 1, in Step 1a, if it is determined that the UE has undergone cell reselection, determine to send the first identifier;

[0469] For Method 2, in Step 1b, if it is determined that the UE has not undergone cell reselection, but meets the first preset condition, for example: when the residence time of the UE in the current cell exceeds the first time threshold, determine to send the first identifier;

[0470] For Method 3, in Step 1c, if a sensing request sent by the base station is received, determine to send the first identifier.

[0471] Step 2: The UE sends the first identifier to the base station.

[0472] Among them, the sensing module can continuously collect energy (to achieve), and can have the functions of an ambient Internet of Things device; specifically, for Method 1: When the communication module and the sensing module are different modules, after the communication module in the UE determines that cell reselection has occurred, it sends indication information to the sensing module in the UE, and this indication information is used to indicate the sensing module to report the first identifier. After receiving this indication information, the sensing module sends the first identifier to the network; or, when the communication module and the sensing module are the same module, after determining that the UE has undergone cell reselection, it determines to send the first identifier to the network (for example, an access network device, taking a base station as an example), and performs this operation, that is, sends the first identifier to the network.

[0473] For Method 2: The sensing module can also report the first identifier to the network without cell reselection occurring; for example, when a UE has stayed in a cell for more than a duration threshold (here referring to the first time threshold), the sensing module of the UE can also report the first identifier to the network.

[0474] For Method 3: After the sensing module receives a sensing request from the network, it sends the first identifier to the network. This sensing request can be a simple sensing signal or a sensing command, and the sensing request is not specifically limited here.

[0475] Optionally, the first identifier can be obtained from the application layer. Or, the first identifier can be informed to the application layer. That is: The first identifier can be obtained from the application layer or other layers of the sensing module or the communication module. If it is obtained from other layers, the first identifier can be notified to the corresponding application layer.

[0476] Optionally, the method further includes:

[0477] Determine not to perform the area update operation anymore; or,

[0478] Determine to reduce the frequency of performing the area update operation.

[0479] Among them, area update can include Tracking Area Update (abbreviated as TAU in English) and Registration Area Udpate (abbreviated as RAU in English). The following takes TAU as an example of area update.

[0480] In the embodiments of this application, after the UE reports the first identifier, the UE can no longer perform the TAU process, or reduce the TAU execution process. For example, reduce the frequency of performing the TAU operation. Optimize the paging process to reduce the power consumption of the UE.

[0481] Optionally, the determination of no longer performing the area update operation includes:

[0482] Receive a first paging message, where the first paging message is used to indicate that the terminal device no longer performs a location update operation.

[0483] Optionally, the first paging message is specifically used to indicate that the terminal device no longer performs a location update operation within a specified first time period.

[0484] In the embodiments of the present application, a special paging message (here, the first paging message) can be used to tell the UE that this paging message is to tell the UE not to do TAU anymore, rather than allowing the UE to access the network. Telling the UE not to do TAU anymore can indicate a time period during which TAU is not performed.

[0485] Exemplarily, Embodiment 2 (UE determines not to perform a location update operation)

[0486] See Figure 3 as shown in Figure 3 the interaction diagram of the paging optimization method provided by the embodiments of the present application Figure 2 . The paging optimization method provided in this embodiment includes the following steps:

[0487] Step 1: The base station sends a paging message to the UE (here, a message used to indicate that the terminal device no longer performs a location update operation, and optionally, a message used to indicate that the terminal device no longer performs a location update operation within a specified first time period).

[0488] Step 2: The UE no longer performs a location update operation. Optionally, the UE no longer performs a location update operation within a specified first time period.

[0489] Optionally, the method further includes:

[0490] Receive a second paging message, where the second paging message is used to indicate that if the terminal device does not receive an indication indicating that the terminal device no longer performs a location update operation within a specified second time period, the terminal device needs to or is allowed to perform a location update operation.

[0491] Among them, the first paging message and the second paging message can be the same message or different messages. If they are the same message, the content carried in the message includes an indication that the terminal device no longer performs a location update operation (or an indication that the terminal device does not perform a location update operation within a specified first time period), and an indication that if the terminal device does not receive an indication indicating that the terminal device no longer performs a location update operation within a specified second time period, the terminal device needs to or is allowed to perform a location update operation. Similarly, the first paging message and the second paging message are respectively the same message or different messages as the third paging message. That is: the first paging message, the second paging message, and the third paging message can be the same message, or two of them can be the same message, or they can be three different messages, which are not specifically limited herein.

[0492] In an embodiment of the present application, within a period of time, if the UE does not receive a paging message from the network (a message that does not allow the UE to perform TAU, which refers to the second paging message here), the UE needs / can perform TAU.

[0493] Exemplarily, in Embodiment 3 (if the UE does not receive an indication of no longer performing a location update operation within a specified second time period, it needs to or is allowed to perform a location update operation)

[0494] See Figure 4 as shown in Figure 4 is an interaction diagram of the paging optimization method provided by an embodiment of the present application Figure 3 . The paging optimization method provided in this embodiment includes the following steps:

[0495] Step 1: The base station sends a paging message to the UE (which refers to a message for indicating that if the terminal device does not receive an indication indicating that the terminal device no longer performs a location update operation within a specified second time period, the terminal device needs to or is allowed to perform a location update operation).

[0496] Step 2: If the UE does not receive an indication of no longer performing a location update operation within a specified second time period, it needs to or can perform a location update operation.

[0497] Optionally, the determining to reduce the frequency of performing a location update operation includes:

[0498] Receiving a third paging message, where the third paging message is used to indicate any one of the following:

[0499] The terminal device performs a location update operation after receiving the third paging message;

[0500] The terminal device performs a location update operation after determining that a second preset condition is met;

[0501] After the terminal device determines that the area update operation has not been performed N times, it performs the area update operation.

[0502] Among them, a paging message can be defined to let the UE perform a TAU. Or, a mechanism or a duration can be defined. After this duration, the UE must perform a TAU. Or, after the UE has not performed a TAU several times (for example, N times, where N is greater than or equal to 1) (where not performing the area update N times means: if according to the current mechanism, the area update should be performed but has not been performed, this counts as one unperformed area update), the UE must perform a TAU.

[0503] Exemplarily, in Embodiment 4 (the UE determines to reduce the frequency of performing the area update operation)

[0504] See Figure 5 as shown Figure 5 which is the interaction diagram of the paging optimization method provided by the embodiment of the present application Figure 4 . The paging optimization method provided in this embodiment includes the following steps:

[0505] Step 1: The base station sends a paging message to the UE (here, it refers to a message used to indicate any of the following: after receiving the third paging message, the terminal device performs the area update operation; after the terminal device determines that the second preset condition is met, it performs the area update operation; after the terminal device determines that the area update operation has not been performed N times, it performs the area update operation).

[0506] Step 2: The UE performs corresponding operations according to the indication: After receiving this paging message, the UE performs the area update operation. Or, the UE determines that a predefined mechanism is met or a certain duration is met. For example, after a predefined duration, the UE must perform a TAU. Or, after determining that the area update operation has not been performed N times, it performs the area update operation.

[0507] In the embodiment of the present application, the terminal device can determine based on the indication in the received paging message that it no longer performs the area update operation or reduces the frequency of performing the area update operation, and can also determine under what specific conditions or scenarios it no longer performs the area update operation, can or needs to perform the area update operation, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0508] Optionally, the method further includes:

[0509] Sending a first message, where the first message is used to indicate that the terminal device supports the paging optimization operation.

[0510] In the embodiments of the present application, if the terminal device supports paging optimization operations, it can send a message carrying the indication information that the terminal device supports paging optimization operations to a network device (such as an access network device or a core network device). Only when the terminal device supports the above operations, will the network device send a sensing request to the terminal device, and the access network device will save and / or inform the core network device of the first identifier. It can be realized that if the terminal device supports paging optimization operations, it can use the sensing process for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, thereby reducing the power consumption of the terminal device.

[0511] Exemplarily, Embodiment 5 (UE supports paging optimization operations)

[0512] See Figure 6 as shown in Figure 6 which is an interaction diagram of the paging optimization method provided by the embodiments of the present application Figure 5 The paging optimization method provided in this embodiment includes the following steps:

[0513] Step 1: The UE sends a message to the base station indicating that the UE supports paging optimization operations.

[0514] Step 2: The base station sends a message to the core network device indicating that the UE supports paging optimization operations

[0515] Optionally, the first identifier is the radio frequency fingerprint of the communication module of the terminal device or the radio frequency fingerprint of the sensing module of the terminal device;

[0516] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0517] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is obtained by the access network device through the communication module or extracted from the information fed back by the sensing module.

[0518] Among them, the first identifier can be a radio frequency fingerprint. The radio frequency fingerprint can be the radio frequency fingerprint of the sensing module or the radio frequency fingerprint of the communication module. Optionally, if it is the radio frequency fingerprint of the communication module, the sensing module and the communication module are the same module. The network can extract the radio frequency fingerprint of the communication module from the information fed back by the communication module as the first identifier; for example, the communication module reflects the signal sent by the network (existing signal or dedicated signal), and the network extracts the radio frequency fingerprint of the communication module through the signal reflected by the communication module as the first identifier. Similarly, the sensing module can also reflect the signal sent by the network (existing signal or dedicated signal), and the network extracts the radio frequency fingerprint of the sensing communication module through the signal reflected by the sensing module as the first identifier.

[0519] The sources of radio frequency fingerprints include manufacturing tolerances and offset tolerances of devices. During the manufacturing process of components, due to the limitations of manufacturing processes, the precision of devices cannot reach an infinitesimal level. Since there are always certain deviations between the actual values and nominal values of device electronic components, even for electronic source components produced by the same manufacturer and in the same batch, there will still be distinguishable differences in the transmitters composed of them. Specifically, it is the combined result of various influencing factors related to the frequency offset, phase noise, digital-to-analog converter, mixer, power amplifier nonlinearity, and filter characteristics of the local oscillator element, which jointly form radio frequency fingerprints with individual distinguishing features. Therefore, radio frequency fingerprints can be used as a unique device or a unique wireless device.

[0520] In the embodiments of the present application, since radio frequency fingerprints can indicate a unique wireless device, radio frequency fingerprints can be used as the identifier of the sensing module and / or communication module of the terminal device. By identifying radio frequency fingerprints, the unique device can be determined to ensure the accuracy of paging.

[0521] Optionally, the method further includes:

[0522] Associating the first identifier with the second identifier to determine the corresponding relationship between the first identifier and the second identifier.

[0523] Among them, associating the first identifier with the second identifier can be before / after determining the first identifier, or before / after sending the first identifier, which is not specifically limited herein.

[0524] Exemplarily, Embodiment Six (associating the first identifier with the second identifier)

[0525] See Figure 7 as shown in Figure 7 is the interaction schematic of the paging optimization method provided by the embodiments of the present application Figure 6 . The paging optimization method provided in this embodiment includes the following steps:

[0526] Step 1: The UE determines the first identifier.

[0527] Step 2: The UE sends the first identifier to the base station.

[0528] Step 3: The UE binds the first identifier and the second identifier.

[0529] Among them, the sequence of Step 2 and Step 3 is not specifically limited.

[0530] Optionally, the associating the first identifier with the second identifier includes:

[0531] Receive a second message through the communication module of the terminal device, where the second message is used to indicate to send the time-frequency resource of the first identifier through the sensing module of the terminal device and the time-frequency resource is only used by the terminal device;

[0532] According to the second message, send the first identifier on the time-frequency resource through the sensing module of the terminal device, and bind the first identifier to the identifier used for paging the terminal device.

[0533] It should be noted that for the binding of the first identifier to the identifier used for paging the terminal device, some operations may also be required by the base station or the access network device. Because by sending the first identifier on the resource through the terminal device, the base station may obtain the identifier of the terminal device used on the air interface of the terminal device, such as C-RNTI; then, the base station needs to determine the identifier used for paging the terminal through the identifier used by the terminal device on the air interface; finally, the binding of the first identifier to the identifier used for paging the terminal device is achieved.

[0534] The UE (or the network) can bind the first identifier to the second identifier (which is fixed), and then based on the third identifier (generated during use, and there is a corresponding relationship between the third identifier and the second identifier), through the corresponding relationship between the second identifier and the third identifier, associate the first identifier with the third identifier to determine the corresponding relationship between the first identifier and the third identifier.

[0535] Specifically, the binding relationship between the first identifier and the second identifier needs to be initialized. Initialization method:

[0536] Method 1: It can be manual operation. For example, in the business hall, the operator operates the device to read the first identifier of the sensing module, obtains the second identifier (such as IMSI), and associates the first identifier with the second identifier. During subsequent use, a new identifier will be generated, which refers to the third identifier (such as TMSI). There is a corresponding relationship between TMSI and IMSI. After TMSI is generated, TMSI can be associated with the first identifier through IMSI. If the mobile phone number is changed, the binding needs to be re-operated.

[0537] Method 2: The above binding relationship can be completed independently with the assistance of the communication module of the UE. For example, the base station tells the UE through the communication module that the sensing module sends the time-frequency resources of the first identifier, and these time-frequency resources are only used by this UE. Then, the sensing module of the UE sends the first identifier on the corresponding resources. In this way, the base station or the core network device (the base station tells the core network the binding relationship between the obtained first identifier and the identifier related to UE communication (here it refers to the second / third identifier, etc.)) can associate the second / third identifier used for UE communication (paging) with the first identifier. Or, the UE can bind the second / third identifier of the UE to the identifier of the sensing module and send it to the network in a secure manner. For example, after the UE enters the connected state and security activation, it is sent to the network through encrypted signaling or data for the network to save.

[0538] In this way, a base station obtains a UE identifier through sensing, queries the database with this identifier to find the corresponding UE, and updates the paging configuration of this UE (such as the cell where the UE is located). Next time the UE paging the UE, it can directly page the UE in this cell.

[0539] In the embodiments of the present application, the terminal device can associate the first identifier and the second identifier and send the corresponding relationship between the first identifier and the second identifier to the network device in a secure manner. During subsequent use, the network device can determine the second identifier based on the first identifier, implement paging the corresponding terminal device based on obtaining the second identifier through sensing, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0540] Optionally, the method further includes:

[0541] indicating, through the communication module of the terminal device, a sensing request signal of the cell where the terminal device camps to the sensing module of the terminal device; and / or,

[0542] responding, through the sensing module of the terminal device, to the sensing request signal indicated by the communication module of the terminal device.

[0543] According to the existing mechanism, the UE can only camp in one cell. However, the sensing module may respond to the sensing requests of multiple cells. For example, for a UE at the cell boundary, it may receive the sensing requests of two cells, and it is necessary to prevent the UE from feeding back the first identifier to both cells, making both cells think that the UE is camping below. A possible method is:

[0544] Method 1: The communication module informs the perception module of the perception request signal of the cell where the terminal device resides, and the perception module only responds to the perception request signal informed by the communication module. At this time, different perception requests are required for different cells. Perception requests can be reused, that is, the perception requests of adjacent cells are different, but the perception requests of non-adjacent cells can be the same. This requires the perception module to have a certain processing capability and requires the perception module to respond only to the specified perception request.

[0545] Method 2: The base station determines whether the UE sending the sensing response resides therein based on the signal strength of the sensing response. A threshold can be set, and the base station considers that the UE resides therein for feedback above the threshold. Alternatively, when the base station sends the first identifier to the core network device, it also carries the signal strength information, and the core network compares and selects the cell with the larger signal strength as the cell where the UE actually resides.

[0546] In addition, no distinction may be made, and each base station that receives the first identifier of the UE considers that the UE resides under it. As a result, future paging will be sent in these multiple cells. However, since there should not be many cells that can receive the first identifier fed back by the UE, sending paging messages in multiple cells is safer and can ensure that the paging is successful without much waste.

[0547] For the overlapping areas of non-terrestrial network (NTN) and terrestrial network (TN), a similar method can be adopted, that is, NTN and TN use different perception request signals, so that the UE residing in NTN will not respond to the perception request of the TN network; so that the UE residing in TN will not respond to the perception request of the NTN network. However, it is also possible to let NTN and TN both page a certain UE if both NTN and TN receive the perception response of the UE. Logically speaking, when NTN and TN cover the overlapping area, the UE will trigger TAU when it moves between NTN and TN. Because the TA encoding of the NTN network and the TN network is different, the UE will trigger TAU, and the network can know whether the UE is in the NTN or TN network. Therefore, even if both NTN and TN receive the perception response of the UE, the core network can distinguish whether the UE is in the cell in TN or NTN.

[0548] In the embodiments of the present application, since the sensing module of the terminal device may respond to sensing requests of multiple cells, in order to prevent the terminal device from feeding back the first identifier to multiple cells and making multiple cells think that the terminal device is camped under them, the communication module of the terminal device may inform the sensing module of the terminal device of the sensing request signal of the cell where the terminal device is camped. In this way, the sensing module only needs to respond to the sensing request signal informed by the communication module, saving paging resources.

[0549] Optionally, the method further includes:

[0550] Receiving a fourth paging message for instructing the terminal device to access an access network device, where the fourth paging message includes a first identifier of the terminal device;

[0551] Accessing the access network device according to the first identifier.

[0552] In the embodiments of the present application, the access of the terminal device to the access network device may be that the terminal device establishes a connection with the access network device, or the terminal device accesses the cell corresponding to the access network device. Here, the first identifier and the second identifier are the same identifier, that is, the first identifier here is the identifier used to page the terminal device. If the terminal device receives a paging message carrying the first identifier, it can directly notify the communication module of the terminal device based on the first identifier to access the access network device, realizing paging based on sensing to avoid or reduce the number of TAUs of the terminal device, thereby reducing the power consumption of the terminal device.

[0553] Exemplarily, Embodiment 7 (Paging Process)

[0554] See Figure 8 as shown in Figure 8 is an interaction diagram of the paging optimization method provided by the embodiments of the present application Figure 7 . The paging optimization method provided in this embodiment includes the following steps:

[0555] Step 1: The core network device sends a paging message 1 to the base station.

[0556] Step 2: The base station sends a paging message 2 to the UE.

[0557] Step 3: The UE accesses the base station.

[0558] Among them, both the paging message 1 and the paging message 2 carry the first identifier of the UE.

[0559] Optionally, the method further includes:

[0560] Determining a method for adopting paging optimization operations;

[0561] Sending a third message, where the third message is used to instruct the terminal device to adopt a paging optimization operation mode;

[0562] The paging optimization operation method includes steps performed by any of the methods described above.

[0563] The UE determines the mode of operation using paging optimization, and also tells the network that it is using this mode to avoid the following situations: if the UE is unaware and performs TAU normally, then it is meaningless to adopt the above optimization scheme (here refers to the scheme implemented by any of the above embodiments); if the network is unaware, and the UE adopts the above TAU optimization process to reduce TAU reporting, the network does not receive the UE's TAU process at the expected TAU time, and the network may think that the UE is abnormal.

[0564] In an embodiment of the present application, the terminal device adopts an optimized TAU process (here refers to the steps of any of the above-mentioned paging optimization methods), which requires the terminal device and the network (here refers to the network device, access network device and / or core network device) to know. This can avoid: if the terminal device does not know, and continues to execute the TAU process, it cannot avoid or reduce the number of times the terminal device performs TAU; if the network does not know, and the terminal device adopts the above-mentioned TAU optimization process, reducing TAU reports, the network does not receive the TAU process of the terminal device at the expected TAU time, the network may think that there is an abnormality in the terminal device, which leads to paging abnormalities and other situations.

[0565] Optionally, the above function (the function of perception-assisted paging, here refers to the above function of supporting paging optimization, that is, the function of realizing paging operation through perception through any of the paging optimization methods) can be turned off. After being turned off, it will no longer respond to the network's reading or perception requests. When the above function is turned off, the network can be informed to prevent the network from obtaining the cell where the UE resides through perception. Similarly, it can be turned on, and after being turned on, the steps of any of the above paging optimization methods can be executed.

[0566] Optionally, if the perception module and the communication module are the same module, then the above operations of the perception module are undertaken by the communication module, that is, the communication module performs the operations performed by the above perception module.

[0567] In this application, the first identifier of the sensing module is associated with the second identifier of the UE for paging; the first identifier of the UE in a cell is obtained through the sensing process, and the first identifier and the cell identifier are sent to the core network device; the core network device finds the second / third identifier according to the first identifier, updates the cell information corresponding to the second / third identifier, and sends a paging message to the UE according to the updated cell information corresponding to the second / third identifier. By using the sensing process, it is realized that the UE moves to a certain cell and feeds back the cell information where the UE is located to the network, avoiding or reducing the number of times the UE performs TAU.

[0568] Therefore, by using the sensing module to assist in sending paging messages, this application can reduce the number of times the UE performs TAU and reduce the power consumption of the UE; at the same time, the UE can be located in a specific cell, which can effectively reduce the paging range and improve the network resource efficiency and energy consumption efficiency.

[0569] It should be noted here that for the paging optimization method with the terminal device as the execution entity provided by this application, the specific implementation process can refer to Figures 1 - 8 the embodiments shown, and the specific implementation process will not be elaborated here.

[0570] See Figure 9 As shown, another embodiment of this application provides a paging optimization method applied to an access network device. The method includes:

[0571] Step 901: Receive a first identifier sent by a terminal device, where the first identifier is an identifier of a sensing module or a second identifier, and the second identifier is an identifier used to page the terminal device;

[0572] Step 902: Send the first identifier to the core network device.

[0573] In the embodiment of this application, the access network device (for example, a base station, hereinafter taking the base station as an example) receives the first identifier sent by the terminal device, that is, the identifier of the sensing module or the second identifier used to page the terminal device, and sends the first identifier to the core network device. By obtaining the identifier of the sensing module of the terminal device in a cell or the second identifier used to page the terminal device through the sensing process, paging based on sensing is realized, without performing TAU or reducing the number of times of TAU, optimizing the paging process, and thus reducing the power consumption of the terminal device.

[0574] Optionally, one access network device corresponds to at least one cell; the method further includes:

[0575] Sending the information of the access network device to the core network device; and / or,

[0576] Sending the cell information where the terminal device resides to the core network device, where the cell information includes the identifier of the cell.

[0577] In an embodiment of the present application, when the base station receives the first identifier sent by the UE, it reports its own information to the core network (device), and / or reports the first identifier and the information of the cell, such as the identifier of the cell.

[0578] Exemplarily, in Embodiment 8 (the base station reports the first identifier of the UE and the identifier of the cell to the core network device)

[0579] See Figure 10 as shown in Figure 10 which is an interaction diagram of the paging optimization method provided by the embodiment of the present application Figure 8 . The paging optimization method provided in this embodiment includes the following steps:

[0580] Step 1: The UE sends a first identifier to the base station.

[0581] Step 2: After receiving the first identifier sent by the UE, the base station sends the first identifier and the identifier of the cell to the core network device.

[0582] Optionally, the method further includes:

[0583] Storing the first identifiers of the terminal devices entering and / or exiting the access network device.

[0584] Wherein, the terminal device entering the access network device may refer to that the terminal device camps on any cell corresponding to the access network device; the terminal device exiting the access network device may refer to that the terminal device exits all cells corresponding to the access network device or the terminal device no longer camps on any cell corresponding to the access network.

[0585] Optionally, sending the first identifier to the core network device includes:

[0586] Periodically sending the first identifiers of the terminal devices entering and / or exiting the access network device stored to the core network device; and / or

[0587] Sending the first identifier of the terminal device newly entering the access network device to the core network device. Wherein, the base station can save the first identifier of the UE under it. For the first identifier of the UE newly camping on the cell under this base station, the base station needs to report it to the core network. Or, the base station can periodically report the first identifiers of the UEs under it saved by it to the core network. Or, the base station periodically sends the first identifiers of the terminal devices that have exited the access network device to the core network device, so that the core network device can delete the corresponding relationship between the access network device and the first identifiers of the terminal devices saved by the core network device.

[0588] In the embodiments of the present application, the access network device can continuously send sensing requests to sense the terminal devices coming in and out under it, especially the incoming terminal devices. If a newly entered terminal device is sensed, the access network device can send its own information and the information of the terminal device (such as the first identifier of the terminal device, the cell identifier where the terminal device resides, etc.) to the core network device, or send it to the core network device periodically. The core network device updates its database. When paging the corresponding terminal subsequently, it preferentially pages the terminal device in this cell (the cell corresponding to the cell identifier where the terminal device reported by the access network device resides in the above process), improving the accuracy of paging success and saving paging resources.

[0589] Optionally, the method further includes:

[0590] Periodically delete the first identifier of the terminal device that has exited the access network device from the storage.

[0591] In the embodiments of the present application, the first identifier of the terminal device that has exited the access network device is deleted. Wherein, the terminal device that has exited the access network device may refer to that the terminal device has exited all the cells corresponding to the access network device or the terminal device no longer resides in any cell corresponding to the access network. In order to save storage resources, the first identifier of the terminal device that has exited the access network device can be periodically deleted to implement storage update.

[0592] Optionally, the method further includes:

[0593] Send a sensing request to the terminal device.

[0594] Optionally, adjacent cells correspond to different sensing requests.

[0595] Wherein, the base station continuously sends sensing requests to sense the terminal devices coming in and out under it, especially the incoming terminal devices. If a newly entered terminal device is sensed, the base station informs the core network device of its own information and the information of the terminal device (such as the first identifier and the cell identifier). The core network device updates its database. When paging the corresponding terminal subsequently, it preferentially pages the terminal in the base station cell.

[0596] In the embodiments of the present application, based on the fact that adjacent cells correspond to different sensing requests, after the access network device sends a sensing request to the terminal device, the terminal device can determine which cell's sensing request it is based on the sensing request signal, avoiding the terminal device from sending the first identifier to multiple cells and making multiple cells think that the terminal device resides under them.

[0597] Optionally, the method further includes:

[0598] Receive the fourth paging message sent by the core network device, where the fourth paging message is used to page the terminal device to access the access network device, and the first identifier of the terminal device is included in the fourth paging message;

[0599] Send a fifth paging message to the terminal device, where the fifth paging message is used to page the terminal device to access the access network device, and the first identifier of the terminal device is included in the fifth paging message.

[0600] In the embodiments of the present application, the first identifier here is the identifier used to page the terminal device. If the access network device receives the first identifier sent by the core network device, it can send the paging message carrying the first identifier to the terminal device. When the terminal device receives the paging message carrying the first identifier, it can directly notify the communication module of the terminal device to access the access network device based on the first identifier, achieving paging based on sensing to avoid or reduce the number of TAUs of the terminal device, thereby reducing the power consumption of the terminal device.

[0601] Optionally, if the ambient IoT solution is used to page the UE, that is: the sensing request carries the first identifier of the UE, and the sensing module obtains the first identifier for the UE and notifies the communication module to access the network. The above solution is also applicable because it is necessary to limit the cell range where the sensing request is sent.

[0602] Exemplarily, Embodiment Nine (Optimization Process of Paging Based on Sensing)

[0603] See Figure 11 as shown Figure 11 is the interaction schematic of the paging optimization method provided by the embodiments of the present application Figure 9 . The paging optimization method provided in this embodiment includes the following steps:

[0604] Step 1: The base station sends a sensing request to the UE.

[0605] Step 2: The UE sends the first identifier to the base station.

[0606] Step 3: The base station saves the first identifier.

[0607] Step 4: The base station sends the first identifier and the identifier of the cell to the core network device (for example, core network + data network).

[0608] Step 5: The core network device obtains the second identifier according to the first identifier and updates the cell information corresponding to the second identifier according to the second identifier.

[0609] Step 6: The core network device obtains the cell information according to the second identifier.

[0610] Step 7: The core network device sends a paging message to the corresponding cell, that is, the core network device sends a first paging message to the base station.

[0611] Step 8: The base station sends a paging message to the UE, that is, the base station sends a second paging message to the UE.

[0612] Optionally, the method further includes:

[0613] Sending a first paging message to the terminal device, where the first paging message is used to instruct the terminal device not to perform a location update operation any more.

[0614] Optionally, the first paging message is specifically used to instruct the terminal device not to perform a location update operation within a specified first time period.

[0615] In the embodiments of the present application, as shown in Figure 3 The network can tell the UE through a special paging message (here referring to the first paging message) that this paging message is to tell the UE not to do TAU any more, rather than allowing the UE to access the network. Telling the UE not to do TAU any more can indicate a time period during which TAU is not performed.

[0616] Optionally, the method further includes:

[0617] Sending a second paging message to the terminal device, where the second paging message is used to instruct the terminal device that if it does not receive an indication from the access network device indicating that the terminal device no longer performs a location update operation within a specified second time period, the terminal device needs to or is allowed to perform a location update operation.

[0618] Wherein, the first paging message and the second paging message may be the same message or different messages. If they are the same message, the content carried in the message includes instructing the terminal device not to perform a location update operation any more (or, instructing the terminal device not to perform a location update operation within a specified first time period), and instructing the terminal device that if it does not receive an indication indicating that the terminal device no longer performs a location update operation within a specified second time period, the terminal device needs to or is allowed to perform a location update operation. Similarly, the first paging message and the second paging message are respectively the same message or different messages as the third paging message. That is: the first paging message, the second paging message, and the third paging message may be the same message, or two of them may be the same message, or they may be three different messages, which is not specifically limited herein.

[0619] In the embodiments of the present application, as shown in Figure 4As shown, the network indicates to the UE via a paging message that within a period of time, if the UE does not receive a paging message from the network (a message that does not allow the UE to perform a TAU, here referring to the second paging message), the UE needs to / can perform a TAU.

[0620] Optionally, the method further includes:

[0621] Sending a third paging message to the terminal device, where the third paging message is used to indicate any one of the following:

[0622] After receiving the third paging message, the terminal device performs a location update operation;

[0623] After the terminal device determines that a second preset condition is met, the terminal device performs a location update operation;

[0624] After the terminal device determines that it has not performed a location update operation N times, the terminal device performs a location update operation.

[0625] Among them, a paging message can be defined to let the UE perform a TAU. Or, a mechanism or a duration can be defined. After this duration, the UE must perform a TAU. Or, after the UE has not performed a TAU several times (for example, N times, where N is greater than or equal to 1) (where not performing a location update N times means: if according to the current mechanism, a location update should be performed but is not, this counts as one time of not performing a location update), the UE must perform a TAU.

[0626] In the embodiments of the present application, in combination with Figure 5 As shown, the access network device can send a paging message to the terminal device to indicate that the terminal device no longer performs a location update operation or reduces the frequency of performing a location update operation, and can also specifically indicate under what conditions or scenarios the location update operation is no longer performed, can be performed, or needs to be performed, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0627] Optionally, the method further includes:

[0628] Receiving a first message, where the first message is used to indicate whether the terminal device supports paging optimization operations.

[0629] In the embodiments of the present application, in combination with Figure 6As shown in the figure, if the terminal device supports paging optimization operations, it can send a message carrying the indication information that the terminal device supports paging optimization operations to a network device (such as an access network device or a core network device). Only when the terminal device supports the above operations, after receiving this message, the access network device will send a sensing request to the terminal device, save and / or inform the core network device of the first identifier. After receiving this message, the core network device will receive the identifier and cell identifier used for paging the terminal device obtained through sensing, and perform paging according to the identifier and cell identifier used for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, sensing processes can be used for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, thereby reducing the power consumption of the terminal device.

[0630] Optionally, the first identifier is the radio frequency fingerprint of the communication module in the terminal device or the radio frequency fingerprint of the sensing module in the terminal device;

[0631] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0632] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is extracted from the information fed back by the access network device through the communication module or the sensing module.

[0633] Among them, the first identifier can be a radio frequency fingerprint. The radio frequency fingerprint can be the radio frequency fingerprint of the sensing module or the radio frequency fingerprint of the communication module. Optionally, if it is the radio frequency fingerprint of the communication module, the sensing module and the communication module are the same module. The network can extract the radio frequency fingerprint of the communication module from the information fed back by the communication module as the first identifier; for example, the communication module reflects the signal sent by the network (existing signal or dedicated signal), and the network extracts the radio frequency fingerprint of the communication module through the signal reflected by the communication module as the first identifier. Similarly, the sensing module can also reflect the signal sent by the network (existing signal or dedicated signal), and the network extracts the radio frequency fingerprint of the sensing communication module through the signal reflected by the sensing module as the first identifier.

[0634] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as the identifier of the sensing module and / or communication module of the terminal device. By identifying the radio frequency fingerprint, a unique device can be determined to ensure the accuracy of paging.

[0635] Optionally, the method further includes:

[0636] Sending a second message, where the second message is used to indicate whether the access network device supports paging optimization operations.

[0637] In the embodiments of the present application, the access network device may send a message indicating its support for paging optimization operations to the terminal device or the core network device. Only when the access network device supports the above operations, will the terminal device send the first identifier to the access network device, and will the core network device receive the identifier and cell identifier used for paging the terminal device sensed by the access network device, and perform paging based on the identifier and cell identifier used for paging the terminal device, thus optimizing the paging operation and reducing the power consumption of the terminal device.

[0638] Exemplarily, Embodiment Ten (the base station supports paging optimization operations)

[0639] See Figure 12 as shown in Figure 12 which is an interaction diagram of the paging optimization method provided by the embodiments of the present application Figure 10 . The paging optimization method provided in this embodiment includes the following steps:

[0640] Step 1: The base station sends a message to the UE indicating that the base station supports paging optimization operations.

[0641] Step 2: The base station sends a message to the core network device indicating that the base station supports paging optimization operations.

[0642] Optionally, the method further includes:

[0643] associating the first identifier with the second identifier to determine the corresponding relationship between the first identifier and the second identifier; or,

[0644] receiving the corresponding relationship between the first identifier and the second identifier.

[0645] In the embodiments of the present application, the base station may bind the first identifier and the second identifier, or may receive the corresponding relationship between the first identifier and the second identifier sent by the UE or the core network device (the UE may bind the first identifier and the second identifier to obtain the corresponding relationship between the first identifier and the second identifier; and / or, the core network device may bind the first identifier and the second identifier to obtain the corresponding relationship between the first identifier and the second identifier). Among them, the operation of the base station associating the first identifier and the second identifier may be after the base station receives the first identifier sent by the UE, and no specific limitation is made here.

[0646] Optionally, the associating the first identifier with the second identifier includes:

[0647] Send a third message to the sensing module of the terminal device through the communication module of the terminal device, where the third message is used to instruct the terminal device to send the time-frequency resources of the first identifier and the time-frequency resources are only used by the terminal device;

[0648] Bind the first identifier to the identifier used for paging the terminal device.

[0649] In the embodiments of the present application, the access network device may associate the first identifier and the second identifier, and send the corresponding relationship between the first identifier and the second identifier to the core network device in a secure manner, or receive the corresponding relationship between the first identifier and the second identifier sent by the terminal device or the core network device. In the subsequent usage process, the network device may determine the second identifier based on the first identifier, implement paging the corresponding terminal device by obtaining the second identifier based on sensing, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0650] Exemplarily, Embodiment XI (associating the first identifier with the second identifier)

[0651] See Figure 13 as shown Figure 13 is an interaction diagram of the paging optimization method provided by the embodiments of the present application Figure 10 One. The paging optimization method provided in this embodiment includes the following steps:

[0652] Step 1: The base station receives the first identifier sent by the UE.

[0653] Step 2: Bind the first identifier to the second identifier.

[0654] Optionally, the method further includes:

[0655] Determine whether the terminal device is camped on the cell under the access network device according to the signal strength of the sensing response sent by the received terminal device.

[0656] The base station selects whether the UE that sends the sensing response is camped on it according to the signal strength of the sensing response. A threshold may be set, and for the feedback higher than the threshold, the base station considers that the UE is camped on it. Or when the base station sends the first identifier to the core network device, it carries the signal strength information at the same time, and the core network compares and selects the cell with the larger signal strength as the cell where the UE actually camps.

[0657] In addition, there is no need to distinguish. When each base station receives the first identifier of the UE, it is considered that the UE is camped under it. As a result, future paging will be sent in these multiple cells. However, since there should not be many cells that can receive the first identifier fed back by the UE, it is relatively safe to send the paging message in multiple cells, which can ensure the success of paging and will not cause much waste.

[0658] In the embodiments of the present application, since the sensing module of the terminal device may respond to the sensing requests of multiple cells, in order to accurately determine whether the terminal device is camped in the cell under the access network device, it can be determined based on the signal strength of the sensing response sent by the received terminal device. If the signal strength is strong or reaches a certain threshold, it can be determined that the terminal device is camped in a certain cell under the access network device.

[0659] Optionally, the method further includes:

[0660] Receiving a fourth message, where the fourth message is used to indicate whether the terminal device adopts an optimized paging operation method;

[0661] Wherein, the method of the paging optimization operation includes the steps performed by any one of the above methods.

[0662] The UE determines to use the method of the optimized paging operation and also tells the network that it is using this method to avoid the following situation: if the UE does not know and performs a normal TAU, then it is meaningless to adopt the above optimization scheme (here refers to the scheme implemented by any one of the above embodiments); if the network does not know and the UE adopts the above TAU optimization process, reducing the TAU reporting, and the network does not receive the TAU process of the UE at the expected TAU moment, the network may consider that the UE is abnormal.

[0663] In the embodiments of the present application, when the terminal device adopts an optimized TAU process (here refers to the steps of any one of the above paging optimization methods), the network (here refers to the network device) needs to know, which can avoid the situation that if the network does not know and the terminal device adopts the above TAU optimization process, reducing the TAU reporting, and the network does not receive the TAU process of the terminal device at the expected TAU moment, the network may consider that the terminal device is abnormal, thus leading to abnormal paging and other situations.

[0664] In this application, the first identifier of the sensing module is associated with the second identifier of the UE for paging; the first identifier of the UE in a cell is obtained through the sensing process, and the first identifier and the cell identifier are sent to the core network device; the core network device finds the second / third identifier according to the first identifier, updates the cell information corresponding to the second / third identifier, and sends a paging message to the UE according to the updated cell information corresponding to the second / third identifier. By using the sensing process, it is realized that the UE moves to a certain cell and feeds back the cell information where the UE is located to the network, avoiding or reducing the number of times the UE performs TAU.

[0665] Therefore, by using the sensing module to assist in sending paging messages, this application can reduce the number of times the UE performs TAU and reduce the power consumption of the UE; at the same time, the UE can be located in a specific cell, which can effectively reduce the paging range and improve the network resource efficiency and energy consumption efficiency.

[0666] It should be noted here that for the paging optimization method with the access network device as the execution entity provided by this application, the specific implementation process can refer to Figures 1 - 13 the embodiments shown, and the specific implementation process will not be elaborated here.

[0667] See Figure 14 As shown, another embodiment of this application provides a paging optimization method applied to a core network device. The method includes:

[0668] Step 1401: Receive the first identifier and the corresponding cell information sent by the access network device. The first identifier has a corresponding relationship with the second identifier, and the second identifier is the identifier used by the paging terminal device. The cell information includes the identifier of the cell.

[0669] Step 1402: Update the cell information corresponding to the second identifier according to the corresponding relationship between the first identifier and the second identifier.

[0670] Among them, the core network device obtains the second identifier according to the first identifier. The second identifier is an identifier related to paging the UE, such as UE IDs like IMSI and TMSI. The cell information is associated with the second identifier. Optionally, the core network device can update the TA information of the UE according to the cell information.

[0671] In the embodiments of this application, in combination with Figure 11As shown, the core network device receives the first identifier sent by the access network device and the identifier of the corresponding cell, and updates the cell information corresponding to the second identifier according to the correspondence between the first identifier and the second identifier used for paging the terminal device. Therefore, through the sensing process, the second identifier of the terminal device under a cell and the corresponding cell information are obtained. During subsequent paging, the terminal device can be preferentially paged in the cell corresponding to the updated cell information, implementing sensing-based paging, without the need to perform TAU or reducing the number of TAU times, optimizing the paging process, and thus reducing the power consumption of the UE.

[0672] Optionally, the method further includes:

[0673] Determine the terminal device to be paged according to the updated cell information corresponding to the first identifier and the second identifier.

[0674] In the embodiments of the present application, the UE to be paged is determined according to the first identifier, and based on the cell information, it is determined in which cell to page the UE. When the core network device sends a paging for the UE, the corresponding cell information is obtained according to the second identifier of the UE, and the UE is preferentially paged in the cell corresponding to the obtained cell information.

[0675] Optionally, the method further includes:

[0676] Determine the second identifier according to the first identifier.

[0677] Optionally, the determining the second identifier according to the first identifier includes:

[0678] Determine the second identifier according to the first identifier through the correspondence between the first identifier and the second identifier.

[0679] In the embodiments of the present application, the second identifier is determined according to the correspondence between the first identifier and the second identifier, and the third identifier is determined according to the correspondence between the second identifier and the third identifier. For example, the second identifier is IMSI, and the third identifier is TMSI.

[0680] Optionally, the method further includes:

[0681] Associate the first identifier with the second identifier to determine the correspondence between the first identifier and the second identifier; or,

[0682] Receive the correspondence between the first identifier and the second identifier.

[0683] Among them, the core network device can bind the first identifier and the second identifier, or receive the correspondence between the first identifier and the second identifier sent by the UE or the access network device (the UE can bind the first identifier and the second identifier to obtain the correspondence between the first identifier and the second identifier; and / or, the access network device can bind the first identifier and the second identifier to obtain the correspondence between the first identifier and the second identifier). Among them, the operation of the core network device associating the first identifier and the second identifier can be after receiving the first identifier sent by the base station, which is not specifically limited here.

[0684] In the embodiments of the present application, the core network device can associate the first identifier and the second identifier, and send the correspondence between the first identifier and the second identifier to the access network device or the terminal device in a secure manner, or receive the correspondence between the first identifier and the second identifier sent by the terminal device or the access network device. During subsequent use, the core network device can determine the second identifier based on the first identifier, implement paging the corresponding terminal device by obtaining or determining the second identifier based on sensing, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0685] Exemplarily, Embodiment Twelve (the core network device associates the first identifier with the second identifier)

[0686] See Figure 15 As shown in Figure 15 FIG. II is an interaction schematic diagram of the paging optimization method provided by the embodiments of the present application. Figure 10 The paging optimization method provided in this embodiment includes the following steps:

[0687] Step 1: The core network device receives the first identifier sent by the base station and the identifier of the cell.

[0688] Step 2: Bind the first identifier and the second identifier.

[0689] Optionally, the method further includes:

[0690] Receiving a first message, where the first message is used to indicate whether the terminal device supports paging optimization operations.

[0691] In the embodiments of the present application, in combination with Figure 6As shown in the figure, if the terminal device supports paging optimization operations, it can send a message carrying the indication information that the terminal device supports paging optimization operations to a network device (for example, an access network device or a core network device). Only when the terminal device supports the above operations, will the network device send a sensing request to the terminal device, and the access network device will save and / or inform the core network device of the first identifier. After receiving this message, the core network device will receive the identifier and cell identifier used for paging the terminal device obtained through sensing, and perform paging based on the identifier and cell identifier used for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, paging can be performed using the sensing process, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, thereby reducing the power consumption of the terminal device.

[0692] Optionally, the first identifier is the radio frequency fingerprint of the communication module in the terminal device or the radio frequency fingerprint of the sensing module in the terminal device;

[0693] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0694] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is extracted from the information fed back by the access network device through the communication module or the sensing module.

[0695] Among them, the first identifier can be a radio frequency fingerprint. The radio frequency fingerprint can be the radio frequency fingerprint of the sensing module or the radio frequency fingerprint of the communication module. Optionally, if it is the radio frequency fingerprint of the communication module, the sensing module and the communication module are the same module. The network can extract the radio frequency fingerprint of the communication module from the information fed back by the communication module as the first identifier; for example, the communication module reflects the signal sent by the network (existing signal or dedicated signal), and the network extracts the radio frequency fingerprint of the communication module through the signal reflected by the communication module as the first identifier. Similarly, the sensing module can also reflect the signal sent by the network (existing signal or dedicated signal), and the network extracts the radio frequency fingerprint of the sensing communication module through the signal reflected by the sensing module as the first identifier.

[0696] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as the identifier of the sensing module and / or communication module of the terminal device. By identifying the radio frequency fingerprint, a unique device can be determined to ensure the accuracy of paging.

[0697] Optionally, the method further includes:

[0698] Sending a second message, where the second message is used to indicate whether the core network device supports paging optimization operations.

[0699] In the embodiments of the present application, if the core network device supports paging optimization operations, it may send a message carrying indication information of supporting paging optimization operations to the terminal device or the access network device. Only when the core network supports the above operations, the core network device will receive the first identifier determined based on sensing and the corresponding cell information, and then determine the second identifier and the corresponding cell for paging the terminal device. In subsequent paging, a paging message is sent to the access network device, and the corresponding terminal device can be paged. If the core network device supports paging optimization operations, it can use the sensing process for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, thereby reducing the power consumption of the terminal device.

[0700] Exemplarily, in Embodiment Thirteen (the core network device supports paging optimization operations)

[0701] See Figure 16 as shown in Figure 16 is the interaction diagram of the paging optimization method provided by the embodiments of the present application Figure 10 Three. The paging optimization method provided in this embodiment includes the following steps:

[0702] Step 1: The core network device sends a message to the base station indicating that the core network device supports paging optimization operations.

[0703] Step 2: The base station sends a message to the UE indicating that the core network device supports paging optimization operations.

[0704] Optionally, the method further includes:

[0705] Sending the first paging information to the access network device according to the updated cell information corresponding to the second identifier and the determined terminal device to be paged. The first paging message is used to page the terminal device in the cell corresponding to the updated cell information, and the first paging message includes the first identifier of the terminal device;

[0706] Wherein, the access network device is used to send a second paging message to the terminal device, and the second paging message is used to page the terminal device to access the access network device, and the second paging message includes the first identifier of the terminal device.

[0707] In the embodiments of the present application, the first identifier here is the second identifier used for paging the terminal device. Combined with Figure 11 as shown in, the core network device can obtain the corresponding updated cell information and the determined terminal device to be paged based on the second identifier, and preferentially page the determined terminal device in the cell corresponding to the obtained cell information, improving the accuracy of paging success and saving paging resources.

[0708] In this application, the first identifier of the sensing module is associated with the second identifier of the UE for paging; the first identifier of the UE in a cell is obtained through the sensing process, and the first identifier and the cell identifier are sent to the core network device; the core network device finds the second / third identifier according to the first identifier, updates the cell information corresponding to the second / third identifier, and sends a paging message to the UE according to the updated cell information corresponding to the second / third identifier. It realizes using the sensing process to sense that the UE moves under a certain cell and feedback the cell information where the UE is located to the network, avoiding or reducing the number of times the UE performs TAU.

[0709] Therefore, by using the sensing module to assist in sending paging messages, this application can reduce the number of times the UE performs TAU and reduce the power consumption of the UE; at the same time, the UE can be located in a specific cell, which can effectively reduce the paging range and improve the network resource efficiency and energy consumption efficiency.

[0710] It should be noted here that for the paging optimization method with the core network device as the execution entity provided in this application, the specific implementation process can refer to Figures 2 - 16 the embodiments shown, and the specific implementation process will not be elaborated here.

[0711] Figure 17 The structural schematic of the paging optimization device provided by the embodiment of this application Figure 1 , as Figure 17 shown, if the paging optimization device provided in this embodiment is applied to a terminal device, the paging optimization device provided in this embodiment includes: a transceiver 1700, configured to receive and send data under the control of a processor 1710.

The bus architecture can also link together various other circuits such as peripheral devices, voltage regulators, and power management circuits, which are well known in the art, and therefore, they will not be further described herein. The bus interface provides an interface. The transceiver 1700 may be multiple elements, that is, including a transmitter and a receiver, and provides a unit for communicating with various other devices on a transmission medium, and these transmission mediums include wireless channels, wired channels, optical fiber cables, etc. For different user devices, the user interface 1730 may also be an interface capable of externally connecting or internally connecting required devices, and the connected devices include but are not limited to a keypad, a display, a speaker, a microphone, a joystick, etc.

[0713] The processor 1710 is responsible for managing the bus architecture and general processing, and the memory 1720 may store the data used by the processor 1710 when performing operations.

[0714] Optionally, the processor 1710 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a complex programmable logic device (CPLD). The processor may also adopt a multi-core architecture.

[0715] The processor 1710 is configured to execute any of the methods provided in the embodiments of the present application according to the obtained executable instructions by calling the program stored in the memory 1720. The processor 1710 and the memory 1720 may also be physically separated.

[0716] In this embodiment, the memory 1720 is configured to store a computer program; the transceiver 1700 is configured to send and receive data under the control of the processor; the processor 1710 is configured to read the computer program in the memory and perform the following operations:

[0717] Determine a first identifier; the first identifier is an identifier of the sensing module or a second identifier, and the second identifier is an identifier used to page the terminal device;

[0718] Send the first identifier.

[0719] In the embodiments of the present application, if the sensing module of the terminal device has its own identifier, the first identifier here may be the identifier of the sensing module. If the sensing module of the terminal device does not have its own identifier or the sensing module does not feedback its identifier, the first identifier here may be the identifier used to page the terminal device, which is not specifically limited herein. The terminal device feeds back the identifier of the sensing module of the terminal device or the second identifier used to page the terminal device to the cell through the sensing process, realizes paging based on sensing, does not need to perform TAU or reduces the number of TAUs, optimizes the paging process, and thus reduces the power consumption of the UE.

[0720] Optionally, when sending the first identifier, the processor 1710 specifically includes any of the following:

[0721] Determine that the terminal device has performed cell reselection, and send the first identifier;

[0722] Determine that the terminal device has not performed cell reselection, but meets a first preset condition, and send the first identifier;

[0723] Receive a sensing request, and send the first identifier.

[0724] In the embodiments of the present application, the terminal device may determine whether to send the first identifier in different ways: Way 1: If it is determined that the terminal device has performed cell reselection, that is, the terminal device has reselected a cell, send the first identifier; Way 2: If it is determined that the terminal device has not performed cell reselection, that is, the terminal device has not reselected a cell, but meets the first preset condition (for example, when the residence time of the terminal device in the current cell exceeds the first time threshold), send the first identifier; Way 3: If the terminal device receives a sensing request, send the first identifier. This realizes the diversification or multiple feasibilities of the operation of sending the first identifier.

[0725] Optionally, the processor 1710 is further configured to perform the following operations:

[0726] Determine not to perform the location update operation anymore; or,

[0727] Determine to reduce the frequency of performing the location update operation.

[0728] Optionally, when the processor 1710 determines not to perform the location update operation anymore, it specifically includes:

[0729] Receive a first paging message, where the first paging message is used to indicate that the terminal device no longer performs the location update operation.

[0730] Optionally, the first paging message is specifically used to indicate that the terminal device does not perform the location update operation within a specified first time period.

[0731] Optionally, the processor 1710 is further configured to perform the following operations:

[0732] Receive a second paging message, where the second paging message is used to indicate that if the terminal device does not receive an indication indicating that the terminal device no longer performs the location update operation within a specified second time period, the terminal device needs to or is allowed to perform the location update operation.

[0733] Optionally, when the processor 1710 determines to reduce the frequency of performing the location update operation, it specifically includes:

[0734] Receive a third paging message, where the third paging message is used to indicate any one of the following:

[0735] After receiving the third paging message, the terminal device performs the location update operation;

[0736] After the terminal device determines that the second preset condition is met, the terminal device performs the location update operation;

[0737] After the terminal device determines that it has not performed the location update operation N times, the terminal device performs the location update operation.

[0738] In an embodiment of the present application, the terminal device may determine based on an indication in a received paging message not to perform a location update operation or reduce the frequency of performing a location update operation, and may also determine under what specific conditions or scenarios it will not perform a location update operation, or can or needs to perform a location update operation, etc., thereby optimizing the paging operation and reducing the power consumption of the terminal device.

[0739] Optionally, the processor 1710 is further configured to perform the following operations:

[0740] Send a first message, where the first message is used to indicate that the terminal device supports paging optimization operations.

[0741] In an embodiment of the present application, if the terminal device supports paging optimization operations, it may send a message carrying indication information that the terminal device supports paging optimization operations to a network device (such as an access network device or a core network device). Only when the terminal device supports the above operations will the network device send a sensing request to the terminal device, and the access network device will save and / or inform the core network device of the first identifier. It can be realized that if the terminal device supports paging optimization operations, it can use the sensing process for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs a TAU, thereby reducing the power consumption of the terminal device.

[0742] Optionally, the first identifier is the radio frequency fingerprint of the communication module of the terminal device or the radio frequency fingerprint of the sensing module of the terminal device;

[0743] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0744] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is obtained by the access network device through the communication module or extracted from the information fed back by the sensing module.

[0745] In an embodiment of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as an identifier for the sensing module and / or communication module of the terminal device. By identifying the radio frequency fingerprint, a unique device can be determined to ensure the accuracy of paging.

[0746] Optionally, the processor 1710 is further configured to perform the following operations:

[0747] Associate the first identifier with the second identifier to determine the corresponding relationship between the first identifier and the second identifier.

[0748] Optionally, when the processor 1710 associates the first identifier with the second identifier, it specifically includes:

[0749] Receiving a second message through the communication module of the terminal device, where the second message is used to indicate that a time-frequency resource with a first identifier is sent through the perception module of the terminal device and that the time-frequency resource is only used by the terminal device;

[0750] According to the second message, the first identifier is sent on the time-frequency resource through the perception module of the terminal device, and the first identifier is bound to the identifier used for paging the terminal device.

[0751] In an embodiment of the present application, the terminal device can associate the first identifier and the second identifier, and send the correspondence between the first identifier and the second identifier to the network device in a secure manner. In the subsequent use process, the network device can determine the second identifier based on the first identifier, and implement paging of the corresponding terminal device based on the perception of the second identifier, thereby optimizing the paging operation, avoiding or reducing the number of times the terminal device performs TAU, and thus reducing the power consumption of the terminal device.

[0752] Optionally, the processor 1710 is further configured to perform the following operations:

[0753] indicating, through the communication module of the terminal device, to the perception module of the terminal device, a perception request signal of the cell in which the terminal device resides; and / or,

[0754] The perception module of the terminal device responds to the perception request signal indicated by the communication module of the terminal device.

[0755] In an embodiment of the present application, since the perception module of the terminal device may respond to perception requests of multiple cells, in order to avoid the terminal device from feeding back the first identifier to multiple cells so that multiple cells believe that the terminal device is residing therein, the communication module of the terminal device can be informed of the perception module of the terminal device of the perception request signal of the cell where the terminal device is residing. In this way, the perception module only needs to respond to the perception request signal informed by the communication module, thereby saving paging resources.

[0756] Optionally, the processor 1710 is further configured to perform the following operations:

[0757] receiving a fourth paging message, where the fourth paging message is used to instruct the terminal device to access the access network device, and the fourth paging message includes a first identifier of the terminal device;

[0758] Access the access network device according to the first identifier.

[0759] In an embodiment of the present application, the access of the terminal device to the access network device may be that the terminal device establishes a connection with the access network device, or the terminal device accesses the cell corresponding to the access network device. The first identifier here is the identifier used to page the terminal device. When the terminal device receives a paging message carrying the first identifier, it can directly notify the communication module of the terminal device to access the access network device based on the first identifier, realizing paging based on sensing to avoid or reduce the number of TAUs performed by the terminal device, thereby reducing the power consumption of the terminal device.

[0760] Optionally, the processor 1710 is further configured to perform the following operations:

[0761] Determine the manner of adopting the paging optimization operation;

[0762] Send a third message, where the third message is used to indicate the manner of adopting the paging optimization operation by the terminal device;

[0763] Wherein, the manner of the paging optimization operation includes the steps performed by the method described in any one of the above.

[0764] In an embodiment of the present application, for the terminal device to adopt an optimized TAU process (here referring to the steps of any one of the above paging optimization methods), both the terminal device and the network (here referring to network devices, access network devices, and / or core network devices) need to know. This can avoid the following situations: If the terminal device does not know and continues to perform the TAU process, it is impossible to avoid or reduce the number of TAUs performed by the terminal device; if the network does not know and the terminal device adopts the above TAU optimization process, reducing the TAU report, and the network does not receive the TAU process of the terminal device at the expected TAU moment, the network may consider that the terminal device is abnormal, leading to situations such as paging anomalies.

[0765] It should be noted here that the paging optimization device provided in the present application can implement all the method steps implemented by the method embodiment described in the first aspect above and can achieve the same technical effects. The same parts and beneficial effects as those in the method embodiment will not be specifically described in this embodiment.

It realizes the diversification or multiple feasibilities of the operation of executing the sending of the first identifier.

[0788] In an embodiment of the present application, the terminal device may determine not to perform an area update operation or reduce the frequency of performing an area update operation based on an indication in the received paging message, and may also determine under what specific conditions or scenarios the terminal device does not perform an area update operation, can or needs to perform an area update operation, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0789] Optionally, the sending unit 1802 is further configured to:

[0790] send a first message, where the first message is used to indicate that the terminal device supports a paging optimization operation.

[0791] In an embodiment of the present application, if the terminal device supports a paging optimization operation, the terminal device may send a message carrying indication information that the terminal device supports a paging optimization operation to a network device (for example, an access network device or a core network device). Only when the terminal device supports the above operation, the network device will send a sensing request to the terminal device, and the access network device will save and / or inform the core network device of the first identifier. It can be realized that if the terminal device supports a paging optimization operation, the terminal device can use the sensing process for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs a TAU, thereby reducing the power consumption of the terminal device.

[0792] Optionally, the first identifier is a radio frequency fingerprint of a communication module of the terminal device or a radio frequency fingerprint of a sensing module of the terminal device;

[0794] If the communication module and the perception module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the perception module is obtained by the access network device through the communication module or extracted from information fed back by the perception module.

[0795] In the embodiment of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as an identifier of the perception module and / or communication module of the terminal device. By identifying the radio frequency fingerprint, the unique device can be determined to ensure the accuracy of paging.

[0796] Optionally, the device further comprises: a processing unit; the processing unit is configured to:

[0797] The first identifier is associated with the second identifier to determine a corresponding relationship between the first identifier and the second identifier.

[0798] Optionally, the processing unit is specifically configured to:

[0800] According to the second message, the first identifier is sent on the time-frequency resource through the perception module of the terminal device, and the first identifier is bound to the identifier used for paging the terminal device.

[0801] In an embodiment of the present application, the terminal device can associate the first identifier and the second identifier, and send the correspondence between the first identifier and the second identifier to the network device in a secure manner. In the subsequent use process, the network device can determine the second identifier based on the first identifier, and implement paging of the corresponding terminal device based on the perception of the second identifier, thereby optimizing the paging operation, avoiding or reducing the number of times the terminal device performs TAU, and thus reducing the power consumption of the terminal device.

[0804] The perception module of the terminal device responds to the perception request signal indicated by the communication module of the terminal device.

[0805] In the embodiments of the present application, since the sensing module of the terminal device may respond to sensing requests of multiple cells, to avoid the terminal device from feeding back the first identifier to multiple cells and making multiple cells think that the terminal device is camped under them, the communication module of the terminal device can be used to inform the sensing module of the terminal device about the sensing request signal of the cell where the terminal device is camped.

[0808] In the embodiments of the present application, the access of the terminal device to the access network device may be that the terminal device establishes a connection with the access network device, or the terminal device accesses the cell corresponding to the access network device. Here, the first identifier is the identifier used to page the terminal device. When the terminal device receives a paging message carrying this first identifier, it can directly notify the communication module of the terminal device based on this first identifier to access the access network device, achieving paging based on sensing to avoid or reduce the number of TAUs of the terminal device, thereby reducing the power consumption of the terminal device.

[0813] It should be noted here that the paging optimization device provided in this application can implement all the method steps implemented in the method embodiments described in the first aspect above, and can achieve the same technical effects. Therefore, the same parts and beneficial effects as those in the method embodiments will not be specifically described in this embodiment.

[0814] Figure 19 Structural schematic of the paging optimization device provided in the embodiments of this application Figure 3 , such as Figure 19 shown, the paging optimization device provided in this embodiment is applied to an access network device. Then, the paging optimization device provided in this embodiment includes: a transceiver 1900, configured to receive and send data under the control of a processor 1910.

[0815] Among them, in Figure 19 , the bus architecture may include any number of interconnected buses and bridges. Specifically, various circuits of one or more processors represented by the processor 1910 and a memory represented by the memory 1920 are linked together. The bus architecture can also link various other circuits such as peripheral devices, voltage regulators, and power management circuits. These are well known in the art, so they will not be further described herein. The bus interface provides an interface. The transceiver 1900 may be multiple elements, that is, including a transmitter and a receiver, and provides a unit for communicating with various other devices on a transmission medium, and these transmission mediums include wireless channels, wired channels, optical cables, and other transmission mediums. The processor 1910 is responsible for managing the bus architecture and general processing, and the memory 1920 may store data used by the processor 1910 when performing operations.

[0816] The processor 1910 may be a central processing unit (CPU), an application specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a complex programmable logic device (CPLD). The processor may also adopt a multi-core architecture.

[0817] In this embodiment, the memory 1920 is configured to store a computer program; the transceiver 1900 is configured to receive and send data under the control of the processor; the processor 1910 is configured to read the computer program in the memory and perform the following operations:

[0818] Receive a first identifier sent by a terminal device, where the first identifier is an identifier of a sensing module or a second identifier, and the second identifier is an identifier used to page the terminal device;

[0819] Send the first identifier to the core network device.

[0820] In the embodiments of the present application, an access network device (such as a base station) obtains the identifier of the sensing module of the terminal device in a cell or the second identifier used for paging the terminal device through a sensing process, and sends the first identifier (i.e., the identifier of the sensing module or the second identifier used for paging the terminal device) received from the terminal device to the core network device, so as to implement paging based on sensing, without performing TAU or reducing the number of TAUs, optimize the paging process, and thus reduce the power consumption of the terminal device.

[0821] Optionally, one access network device corresponds to at least one cell; the processor 1910 is further configured to perform the following operations:

[0822] Send the information of the access network device to the core network device; and / or,

[0823] Send the cell information where the terminal device camps to the core network device, where the cell information includes the identifier of the cell.

[0824] Optionally, the processor 1910 is further configured to perform the following operations:

[0825] Store the first identifiers of the terminal devices entering and / or exiting the access network device.

[0826] Wherein, the entry into the access network device may be entering or camping to at least one cell corresponding to the access network device.

[0827] Optionally, when sending the first identifier to the core network device, the processor 1910 specifically includes:

[0828] Periodically send the first identifiers of the terminal devices entering and / or exiting the access network device stored to the core network device; and / or,

[0829] Send the first identifier of the terminal device newly entering the access network device to the core network device.

[0830] In an embodiment of the present application, the access network device can sense the terminal devices entering and exiting it, especially the incoming terminal devices, by continuously sending perception requests. If a newly entered terminal device is sensed, its own information and the terminal device's information (for example, the first identifier of the terminal device, the identifier of the cell where the terminal device resides, etc.) can be sent to the core network device, or periodically sent to the core network device. The core network device updates its database, and when paging the corresponding terminal subsequently, it will give priority to paging the terminal device in the cell (in the above process, the cell corresponding to the cell identifier where the terminal device resides reported by the access network device), thereby improving the accuracy of paging success and saving paging resources.

[0831] Optionally, the processor 1910 is further configured to perform the following operations:

[0832] The first identification of the terminal device that exits the access network device is periodically deleted.

[0833] In the embodiment of the present application, in order to save storage resources, the first identification of the terminal device exiting the access network device can be periodically deleted to implement updated storage.

[0834] Optionally, the processor 1910 is further configured to perform the following operations:

[0835] Send a sensing request to the terminal device.

[0836] Optionally, adjacent cells correspond to different perception requests.

[0837] In an embodiment of the present application, based on the different perception requests corresponding to adjacent cells, after the access network device sends a perception request to the terminal device, the terminal device can determine which cell the perception request is from based on the perception request signal, thereby avoiding the terminal device from feeding back the first identifier to multiple cells, causing multiple cells to believe that the terminal device is residing therein.

[0838] Optionally, the processor 1910 is further configured to perform the following operations:

[0839] A first paging message is sent to the terminal device, where the first paging message is used to indicate that the terminal device no longer performs an area update operation.

[0840] Optionally, the first paging message is specifically used to instruct the terminal device not to perform an area update operation within a specified first time period.

[0841] Optionally, the processor 1910 is further configured to perform the following operations:

[0842] Send a second paging message to the terminal device, where the second paging message is used to indicate that if the terminal device does not receive an indication sent by the access network device indicating that the terminal device no longer performs a location update operation within a specified second time period, the terminal device needs to or is allowed to perform a location update operation.

[0843] Optionally, the processor 1910 is further configured to perform the following operations:

[0844] Send a third paging message to the terminal device, where the third paging message is used to indicate any of the following:

[0845] After receiving the third paging message, the terminal device performs a location update operation;

[0846] After the terminal device determines that a second preset condition is satisfied, the terminal device performs a location update operation;

[0847] After the terminal device determines that it has not performed a location update operation N times, the terminal device performs a location update operation.

[0848] In the embodiments of the present application, the access network device may send a paging message to the terminal device to indicate that the terminal device no longer performs a location update operation or reduces the frequency of performing a location update operation, and may also specifically indicate under what conditions or scenarios the terminal device no longer performs a location update operation, can or needs to perform a location update operation, etc., thereby optimizing the paging operation and reducing the power consumption of the terminal device.

[0849] Optionally, the processor 1910 is further configured to perform the following operations:

[0850] Receive a first message, where the first message is used to indicate whether the terminal device supports paging optimization operations.

[0851] In the embodiments of the present application, if the terminal device supports paging optimization operations, the terminal device may send a message carrying indication information that the terminal device supports paging optimization operations to a network device (for example, an access network device or a core network device). Only when the terminal device supports the above operations, after receiving the message, the access network device will send a sensing request to the terminal device, will save and / or inform the core network device of the first identifier, and after receiving the message, the core network device will receive an identifier and a cell identifier for paging the terminal device obtained based on sensing, and perform paging according to the identifier and the cell identifier for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, sensing can be used for paging, avoiding or reducing the number of times the terminal device (such as a UE) performs a TAU, thereby reducing the power consumption of the terminal device.

[0852] Optionally, the first identifier is the radio frequency fingerprint of the communication module in the terminal device or the radio frequency fingerprint of the sensing module in the terminal device;

[0853] If the communication module and the sensing module are the same module, the radio frequency fingerprint of the communication module and the radio frequency fingerprint of the sensing module are the same radio frequency fingerprint;

[0854] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is extracted from the information fed back by the access network device through the communication module or the sensing module.

[0855] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as the identifier of the sensing module and / or the communication module of the terminal device. By identifying the radio frequency fingerprint, the unique device can be determined to ensure the accuracy of paging.

[0856] Optionally, the processor 1910 is further configured to perform the following operations:

[0857] Send a second message, where the second message is used to indicate whether the access network device supports paging optimization operations.

[0858] In the embodiments of the present application, the access network device can send a message indicating that it supports paging optimization operations to the terminal device or the core network device. Only when the access network device supports the above operations, the terminal device will send the first identifier to the access network device, and the core network device will receive the identifier and the cell identifier used for paging the terminal device obtained by the access network device based on sensing, and perform paging based on the identifier and the cell identifier used for paging the terminal device, optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0859] Optionally, the processor 1910 is further configured to perform the following operations:

[0860] Associate the first identifier with the second identifier to determine the corresponding relationship between the first identifier and the second identifier; or,

[0861] Receive the corresponding relationship between the first identifier and the second identifier.

[0862] Optionally, when the processor 1910 associates the first identifier with the second identifier, it specifically includes:

[0863] Send a third message through the communication module of the terminal device to the sensing module of the terminal device, where the third message is used to indicate the time-frequency resource for the terminal device to send the first identifier through the sensing module of the terminal device, and the time-frequency resource is only used by the terminal device;

[0864] Bind the first identifier to the identifier used for paging the terminal device.

[0865] In the embodiments of the present application, the access network device may associate the first identifier and the second identifier, and send the corresponding relationship between the first identifier and the second identifier to the core network device in a secure manner, or receive the corresponding relationship between the first identifier and the second identifier sent by the terminal device or the core network device. During subsequent use, the network device may determine the second identifier based on the first identifier, implement paging the corresponding terminal device by obtaining the second identifier based on sensing, optimize the paging operation, avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0866] Optionally, the processor 1910 is further configured to perform the following operations:

[0867] Determine whether the terminal device is camped on a cell under the access network device according to the signal strength of the sensing response sent by the received terminal device.

[0868] In the embodiments of the present application, since the sensing module of the terminal device may respond to sensing requests of multiple cells, in order to accurately determine whether the terminal device is camped on a cell under the access network device, it may be determined based on the signal strength of the sensing response sent by the received terminal device. If the signal strength is strong or reaches a certain threshold, it may be determined that the terminal device is camped on a certain cell under the access network device.

[0869] Optionally, the processor 1910 is further configured to perform the following operations:

[0871] Send a fifth paging message to the terminal device, where the fifth paging message is used to page the terminal device to access the access network device, and the fifth paging message includes the first identifier of the terminal device.

[0872] In the embodiments of the present application, the first identifier here is the identifier used to page the terminal device. If the access network device receives the first identifier sent by the core network device, it may send a paging message carrying the first identifier to the terminal device. When the terminal device receives the paging message carrying the first identifier, it may directly notify the communication module of the terminal device to access the access network device based on the first identifier, implementing paging based on sensing to avoid or reduce the number of times the terminal device performs TAU, thereby reducing the power consumption of the terminal device.

[0873] Optionally, the processor 1910 is further configured to perform the following operations:

[0874] Receive a fourth message, where the fourth message is used to indicate whether the terminal device adopts an optimized paging operation method;

[0875] Wherein, the method of the paging optimization operation includes the steps performed by the method described in any one of the above.

[0876] In the embodiments of the present application, when the terminal device adopts an optimized TAU process (here referring to the steps of any one of the above paging optimization methods), the network (here referring to the network device) needs to know. This can avoid the situation that if the network does not know and the terminal device adopts the above TAU optimization process, resulting in a reduction in TAU reporting. At the expected TAU moment, the network does not receive the TAU process of the terminal device, and the network may consider the terminal device to be abnormal, thus leading to abnormal paging and other situations.

[0877] It should be noted here that the paging optimization device provided in the present application can implement all the method steps implemented in the method embodiments described in the second aspect above, and can achieve the same technical effects. The same parts and beneficial effects as those in the method embodiments will not be specifically described in this embodiment.

[0878] Figure 20 The structural schematic of the paging optimization device provided in the embodiments of the present application Figure 4 , as Figure 20 shown, if the paging optimization device provided in this embodiment is applied to an access network device, the paging optimization device 2000 provided in this embodiment includes:

[0880] A sending unit 2002, configured to send the first identifier to a core network device.

[0881] In the embodiments of the present application, the access network device (such as a base station) receives the first identifier sent by the terminal device, that is, the identifier of the sensing module or the second identifier used for paging the terminal device, and sends the first identifier to the core network device. By obtaining the identifier of the sensing module of the terminal device in a cell or the second identifier used for paging the terminal device through the sensing process, paging based on sensing is realized, without performing TAU or reducing the number of TAUs, optimizing the paging process, and thus reducing the power consumption of the terminal device.

[0882] Optionally, one access network device corresponds to at least one cell; the sending unit 2002 is further configured to:

[0883] Send the information of the access network device to the core network device; and / or,

[0891] In the embodiments of the present application, the access network device can continuously send sensing requests to sense the terminal devices entering and leaving under it, especially the entering terminal devices. If a newly entered terminal device is sensed, it can send its own information and the information of the terminal device (such as the first identifier of the terminal device, the cell identifier where the terminal device resides, etc.) to the core network device, or send it to the core network device periodically. The core network device updates its database. When paging the corresponding terminal subsequently, it preferentially pages the terminal device in this cell (the cell corresponding to the cell identifier where the terminal device resides reported by the access network device in the above process), improving the accuracy of paging success and saving paging resources.

[0892] Optionally, the device further includes: a processing unit; the processing unit is used for:

[0893] Periodically delete the first identifier of the terminal device exiting the access network device stored.

[0894] In the embodiments of the present application, in order to save storage resources, the first identifier of the terminal device exiting the access network device can be periodically deleted to implement storage update.

[0895] Optionally, the sending unit 2002 is further used for:

[0896] Send a sensing request to the terminal device.

[0897] Optionally, adjacent cells correspond to different sensing requests.

[0898] In the embodiments of the present application, based on the fact that adjacent cells correspond to different sensing requests, after the access network device sends a sensing request to the terminal device, the terminal device can determine which cell's sensing request it is based on the sensing request signal, avoiding the terminal device from feeding back the first identifier to multiple cells and making multiple cells think that the terminal device is camping under them.

[0899] Optionally, the sending unit 2002 is further configured to:

[0907] After the terminal device determines that a second preset condition is satisfied, the terminal device performs a location update operation;

[0908] After the terminal device determines that it has not performed a location update operation N times, the terminal device performs a location update operation.

[0909] In the embodiments of the present application, the access network device can send a paging message to the terminal device to indicate that the terminal device no longer performs a location update operation or reduces the frequency of performing a location update operation, and can also specifically indicate under what conditions or scenarios the terminal device no longer performs a location update operation, can or needs to perform a location update operation, etc., optimizing the paging operation, thereby reducing the power consumption of the terminal device.

[0910] Optionally, the receiving unit 2001 is further configured to:

[0912] In the embodiments of the present application, if the terminal device supports paging optimization operations, the terminal device may send a message carrying indication information that the terminal device supports paging optimization operations to a network device (for example, an access network device or a core network device). Only when the terminal device supports the above operations, after receiving this message, the access network device will send a sensing request to the terminal device, save and / or inform the core network device of the first identifier. After receiving this message, the core network device will receive the identifier and cell identifier used for paging the terminal device obtained based on sensing, and perform paging according to the identifier and cell identifier used for paging the terminal device. It can be realized that after determining that the terminal device supports paging optimization operations, paging can be performed using the sensing process, avoiding or reducing the number of times the terminal device (such as a UE) performs TAU, thereby reducing the power consumption of the terminal device.

[0915] If the communication module and the sensing module are different modules, the radio frequency fingerprint of the communication module or the radio frequency fingerprint of the sensing module is extracted from the information fed back by the access network device through the communication module or the sensing module.

[0916] In the embodiments of the present application, since the radio frequency fingerprint can indicate a unique wireless device, the radio frequency fingerprint can be used as the identifier of the sensing module and / or communication module of the terminal device. By identifying the radio frequency fingerprint, the unique device can be determined to ensure the accuracy of paging.

[0917] Optionally, the sending unit 2002 is further configured to:

[0919] In an embodiment of the present application, the access network device can send a message to the terminal device or the core network device that it supports the paging optimization operation. Only when the access network device supports the above operation, the terminal device will send the first identifier to the access network device, and the core network device will receive the identifier and cell identifier used for paging the terminal device based on the perception of the access network device, and perform paging based on the identifier and cell identifier used for paging the terminal device, thereby optimizing the paging operation and reducing the power consumption of the terminal device.

[0923] Sending a third message to the perception module of the terminal device through the communication module of the terminal device, wherein the third message is used to instruct the terminal device to send the time-frequency resource of the first identifier through the perception module of the terminal device and the time-frequency resource is only used by the terminal device;

[0924] Binding is performed according to the first identifier and the identifier used for paging the terminal device.

[0925] In an embodiment of the present application, the access network device can associate the first identifier and the second identifier, and send the correspondence between the first identifier and the second identifier to the core network device in a secure manner, or receive the correspondence between the first identifier and the second identifier sent by the terminal device or the core network device.

[0926] Optionally, the processing unit is further configured to:

[0927] According to the signal strength of the received perception response sent by the terminal device, it is determined whether the terminal device resides in the cell under the access network device.

[0928] In an embodiment of the present application, since the perception module of the terminal device may respond to perception requests of multiple cells, in order to more accurately determine whether the terminal device resides in a cell under the access network device, it can be determined based on the signal strength of the perception response sent by the terminal device. If the signal strength is strong or reaches a certain threshold, it can be determined that the terminal device resides in a cell under the access network device.

[0929] Optionally, the receiving unit 2001 is further configured to: receive fourth paging information sent by a core network device, where the fourth paging message is used to page the terminal device to access the access network device, and the fourth paging message includes a first identifier of the terminal device;

[0930] The sending unit 2002 is further configured to send a fifth paging message to the terminal device, where the fifth paging message is used to page the terminal device to access the access network device, and the fifth paging message includes the first identifier of the terminal device.

[0931] In the embodiment of the present application, the first identifier here is the identifier used to page the terminal device. If the access network device receives the first identifier sent by the core network device, it can send a paging message carrying the first identifier to the terminal device. When the terminal device receives the paging message carrying the first identifier, it can directly notify the communication module of the terminal device to access the access network device based on the first identifier, realizing paging based on perception to avoid or reduce the number of TAUs of the terminal device, thereby reducing the power consumption of the terminal device.

[0935] In the embodiment of the present application, for the terminal device to adopt an optimized TAU process (here referring to the steps of any one of the above paging optimization methods), the network (here referring to the network device) needs to know. This can avoid the situation where if the network does not know and the terminal device adopts the above TAU optimization process, reducing the TAU report, and the network does not receive the TAU process of the terminal device at the expected TAU moment, and the network may consider the terminal device to be abnormal, thereby leading to abnormal paging and other situations.

[0936] It should be noted here that the paging optimization device provided in the present application can implement all the method steps implemented by the method embodiment described in the second aspect above, and can achieve the same technical effect. The same parts and beneficial effects as those in the method embodiment will not be specifically described in this embodiment.

Therefore, by means of a sensing process, the second identifier of a terminal device in a cell and the corresponding cell information are obtained. During subsequent paging, the terminal device can be preferentially paged in the cell corresponding to the updated cell information, realizing paging based on sensing, without performing a TAU or reducing the number of TAUs, optimizing the paging process, and thus reducing the power consumption of the UE.
