Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and in particular to a paging method and apparatus. Background Technology

[0002] In communication systems, paging packet information for inactive terminal devices is typically allocated by the access network equipment, while for idle terminal devices, it is allocated by the core network equipment. If the context of an inactive terminal device is lost on the network side, the access network equipment may mistakenly assume the terminal device is idle and attempt to paging according to the paging packet information allocated by the core network equipment. Meanwhile, the terminal device may still be using the paging packet information allocated by the access network equipment for eavesdropping, leading to paging failure and increased power consumption. Therefore, reducing the probability of paging failure and the terminal's power consumption is a pressing issue that needs to be addressed. Summary of the Invention

[0118] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present disclosure. The communication system may include, but is not limited to, a core network device, an access network device, and a terminal device. Figure 1The number and form of devices shown are for illustrative purposes only and do not constitute a limitation on the embodiments of this disclosure.

By adopting the CU-DU structure, the protocol layer of the access network device, such as a base station, can be separated. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, etc. The embodiments of this disclosure do not limit the specific technology or device form used in the terminal device.

[0122] It is understood that the communication system described in the embodiments of this disclosure is for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and does not constitute a limitation on the technical solutions provided in the embodiments of this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this disclosure are also applicable to similar technical problems.

[0123] The paging method and apparatus provided in this disclosure will now be described in detail with reference to the accompanying drawings.

[0124] Please see Figure 2 , Figure 2 This is a flowchart illustrating a paging method provided in an embodiment of this disclosure. The method is configured to be executed by an access network device. Figure 2 As shown, the method may include, but is not limited to, the following steps:

[0125] Step 21: Send the paging assistance information corresponding to the terminal device to the core network equipment.

[0126] Among them, paging auxiliary information can be used to assist core network equipment in determining the first paging packet information of terminal equipment in idle state.

[0127] Optionally, the first paging packet information may be any one or more of the following: paging packet identifier, paging probability, paging probability indication, and paging cycle.

[0128] The paging packet identifier can be the packet identifier that the core network device determines when the terminal device is in an idle state. The core network device can send a paging message to the terminal device based on the paging packet identifier.

[0129] Among them, the paging probability can be the probability determined by the core network equipment that a terminal device is paging when it is in an idle state.

[0130] The paging probability indicator can be a probability indicator determined by the core network equipment of being paged when the terminal device is in an idle state. The paging probability indicator can be high, medium, or low.

[0131] The paging period can be defined as the interval between two consecutive paging messages sent to a terminal device when the terminal device is in an idle state, as determined by the core network equipment.

[0132] Optionally, the paging assistance information may include the second paging packet information corresponding to the terminal device in the inactive state, as determined by the access network device.

[0133] Optionally, the access network device may determine the second paging packet information of the terminal device in the inactive state according to the protocol, and then synchronize the corresponding second paging packet information in the inactive state to the core network device by sending paging assistance information.

[0134] Optionally, the access network device may also determine the second paging packet information of the terminal device in the inactive state after receiving the indication information sent by the core network device, and synchronize the corresponding second paging packet information in the inactive state to the core network device by sending paging assistance information.

[0135] Optionally, the access network device may also determine the second paging packet information of the terminal device in the inactive state when it does not receive the indication information from the core network device, and synchronize the corresponding second paging packet information in the inactive state to the core network device by sending paging assistance information.

[0136] Therefore, in this embodiment of the present disclosure, the core network device determines the first paging packet information of the terminal device in the idle state based on the paging assistance information sent by the access network device. This enables the network side to accurately determine the second paging packet information of the terminal device in the inactive state based on the first paging packet information and the paging assistance information of the terminal device, even if the context information of the terminal device is lost, and to accurately paging the terminal device. This not only improves the paging success rate, but also reduces the power consumption of the terminal during the paging process.

[0137] By implementing the embodiments of this disclosure, the access network device sends paging assistance information corresponding to the terminal device to the core network device. This paging assistance information assists the core network device in determining the first paging packet information of the terminal device in the idle state. This ensures that the core network device and the access network device have a consistent understanding of the terminal device's paging information regardless of whether the terminal device is in an inactive or idle state, thereby reducing the probability of paging failure and lowering the power consumption of the terminal device.

[0138] Please see Figure 3 , Figure 3 This is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by an access network device. Figure 3 As shown, the method may include, but is not limited to, the following steps:

[0139] Step 31: According to the agreement, determine the second paging packet information of the terminal device in the inactive state.

[0140] Step 32: Determine paging auxiliary information based on the second paging group information.

[0141] The second paging packet information may include the paging packet identifier of the terminal device in the inactive state, the paging probability, the paging probability indication, and the paging cycle.

[0142] Optionally, the paging assistance information may include second paging group information.

[0143] The specific implementation process of steps 31 and 32 above can be referred to in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0144] Step 33: Send the paging assistance information corresponding to the terminal device to the core network equipment.

[0145] Among them, paging auxiliary information can be used to assist core network equipment in determining the first paging packet information of terminal equipment in idle state.

[0146] By implementing the embodiments of this disclosure, the access network device determines the second paging packet information of the terminal device in the inactive state according to the protocol, then determines the paging assistance information based on the second paging packet information, and finally sends the paging assistance information corresponding to the terminal device to the core network device. This ensures that the core network device and the access network device have a consistent understanding of the terminal device's paging information regardless of whether the terminal device is in an inactive or idle state, thereby reducing the probability of paging failure and reducing the power consumption of the terminal device.

[0147] Please see Figure 4 , Figure 4This is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by an access network device. Figure 4 As shown, the method may include, but is not limited to, the following steps:

[0148] Step 41: In response to receiving the first indication information sent by the core network device, determine the second paging packet information of the terminal device in the inactive state.

[0149] Optionally, the first instruction information can be any one or more of the following:

[0150] Initial context setup request;

[0151] UE context modification request;

[0152] Handover request; and,

[0153] Path switch request acknowledge.

[0154] Optionally, the first indication information may be used at least to indicate whether the access network device is allowed to determine the second paging packet information of the terminal device when it is inactive.

[0155] Optionally, if the first indication information indicates that the access network device is allowed to determine the second paging packet information of the terminal device in the inactive state, the access network device may determine the second paging packet information of the terminal device in the inactive state based on the protocol agreement or configuration information.

[0156] Step 42: Determine paging auxiliary information based on the second paging group information.

[0157] Among them, paging auxiliary information is used to assist core network equipment in determining the first paging packet information of terminal equipment when it is in idle state.

[0158] Optionally, paging assistance information can be second paging packet information, or it can be paging probability, paging cycle, or paging probability indication, etc. For example, the access network device does not allocate first paging packet information in the idle state to the terminal device, but only provides paging probability to the core network device, so that the core network device can allocate first paging packet information in the idle state to the terminal device, or allocate second paging packet information in the inactive state to the terminal device.

[0159] Step 43: Send a second instruction message to the core network equipment, wherein the second instruction message includes paging assistance information.

[0160] Optionally, the second instruction information may be one or more of the following:

[0161] Radio Resource Control (RRC) inactive transition report;

[0162] The initial context setup response; or,

[0163] UE context modification response;

[0164] UE context modification indication;

[0165] UE context suspend request;

[0166] Retrieve UE information;

[0167] Handover request acknowledgement; and,

[0168] Path switch request.

[0169] The specific implementation of steps 42-44 can be found in the detailed descriptions of other embodiments of this disclosure, and will not be repeated here.

[0170] By implementing the embodiments of this disclosure, the access network device, in response to receiving the first indication information sent by the core network device, determines the second paging packet information of the terminal device in the inactive state. Then, based on the second paging packet information, it determines paging assistance information, and finally sends the second indication information, including the paging assistance information corresponding to the terminal device, to the core network device. This ensures that regardless of whether the terminal device is in an inactive or idle state, the core network device and the access network device have a consistent understanding of the terminal device's paging information, thereby reducing the probability of paging failure and lowering the power consumption of the terminal device.

[0171] Please see Figure 4a , Figure 4aThis is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by an access network device. Figure 4a As shown, the method may include, but is not limited to, the following steps:

[0172] Step 45: Determine paging assistance information.

[0173] Among them, paging auxiliary information is used to assist core network equipment in determining the first paging packet information of terminal equipment when it is in idle state.

[0174] Optionally, paging assistance information can be the second paging packet information in the inactive state assigned by the access network device to the terminal device.

[0175] Alternatively, paging assistance information can also include paging probability, paging cycle, or paging probability indication, etc. For example, the access network device only provides the paging probability to the core network device, so that the core network device can allocate the first paging packet information in the idle state to the terminal device, or allocate the second paging packet information in the inactive state to the terminal device.

[0176] Optionally, the access network device may determine paging assistance information based on protocol agreements.

[0177] Alternatively, paging assistance information can be determined in response to receiving the first indication information sent by the core network equipment.

[0178] Alternatively, paging assistance information may be determined in response to the failure to receive the first indication information from the core network equipment. This disclosure does not limit this.

[0190] By implementing the embodiments of this disclosure, the access network device, in response to receiving the first indication information sent by the core network device, determines the paging assistance information, and then can send a second indication information including the paging assistance information to the core network device. This ensures that regardless of whether the terminal device is in an inactive or idle state, the core network device and the access network device have a consistent understanding of the terminal device's paging information, thereby reducing the probability of paging failure and lowering the power consumption of the terminal device.

[0212] By implementing the embodiments of this disclosure, in response to not receiving the first indication information sent by the core network device, the access network device determines the second paging packet information of the terminal device in the inactive state. Then, based on the second paging packet information, it determines paging assistance information, and finally sends the second indication information, including the paging assistance information corresponding to the terminal device, to the core network device. This ensures that regardless of whether the terminal device is in an inactive or idle state, the core network device and the access network device have a consistent understanding of the terminal device's paging information, thereby reducing the probability of paging failure and lowering the power consumption of the terminal device.

[0213] Please see Figure 6 , Figure 6 This is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by an access network device. Figure 6 As shown, the method may include, but is not limited to, the following steps:

[0214] Step 61: Send paging assistance information corresponding to the terminal device to the core network device, wherein the paging assistance information is used to assist the core network device in determining the first paging packet information of the terminal device in the idle state.

[0215] The specific implementation process and method of step 61 can be found in the detailed description of any embodiment of this disclosure, and will not be repeated here.

[0216] Step 62: In response to the terminal device changing from the active state to the idle state, update the first paging packet information corresponding to the terminal device in the idle state.

[0217] Because the paging probability and paging cycle of a terminal device may differ in the inactive and idle states, the power consumed by the terminal device during the paging process also differs between the inactive and idle states. In this disclosure, when the terminal device is in the inactive state, the core network device determines its first paging packet information in the idle state based on its second paging packet information in the inactive state. This ensures that even if the network side loses the context information of the terminal device, paging failure will not occur.

[0218] To minimize the power consumption of terminal devices during paging, if the access network device still uses the second paging packet information from the inactive state to paging the terminal device after determining that the terminal device has entered the idle state from the active state, it may cause additional power loss. Therefore, the access network device can update the first paging packet information corresponding to the terminal device in the idle state, so that the access network device can send the paging message to the terminal device in the idle state using the new first paging packet information, thereby reducing the power consumption of the terminal device during paging.

[0219] Optionally, the access network device can update the first paging packet information corresponding to the terminal device in the idle state based on the paging message sent by the core network device.

[0220] That is, the first paging packet information corresponding to the terminal device in the idle state is determined and updated by the core network device. Then, when the core network device paging the terminal device based on the updated first paging packet information, the access network device can determine the updated first paging packet information based on the paging message.

[0221] Optionally, the access network device may also update the first paging packet information corresponding to the terminal device in the idle state according to the protocol.

[0222] That is, the access network device determines, according to the protocol or the instruction of the core network device, that it can allocate the first paging packet information in the idle state to the terminal device. Thus, when the access network device determines that the terminal device has entered the idle state from the inactive state, it can allocate the new first paging packet information to the terminal device in the idle state according to the protocol and overwrite the previous first paging packet information with the new first paging packet information.

[0223] Step 63: Send a Radio Resource Control (RRC) release message to the terminal device, wherein the RRC release message includes the updated first paging packet information.

[0224] Among them, the Radio Resource Control (RRC) release message can be used to instruct the terminal device to use the updated first paging packet information for paging listening.

[0225] By implementing the embodiments of this disclosure, in response to a terminal device entering an idle state from an active state, the access network device updates the first paging packet information corresponding to the terminal device in the idle state, and then sends a Radio Resource Control (RRC) release message including the updated first paging packet information to the terminal device. Thus, when the terminal device enters an idle state from an active state, both the access network device and the core network device use the updated first paging packet information to send a paging message to the terminal device in the idle state, and the terminal device also uses the updated first paging packet information for paging listening. This not only increases the probability of successful paging but also reduces the power consumption of the terminal device.

[0226] Please see Figure 7 , Figure 7 This is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by a core network device. Figure 7 As shown, the method may include, but is not limited to, the following steps:

[0227] Step 71: Receive paging assistance information corresponding to the terminal device sent by the access network device.

[0228] Among them, paging auxiliary information can be used to assist core network equipment in determining the first paging packet information of terminal equipment in idle state.

[0229] Optionally, the paging assistance information may include the second paging packet information corresponding to the terminal device in the inactive state, as determined by the access network device.

[0230] Optionally, the access network device may determine the second paging packet information of the terminal device in the inactive state according to the protocol, and then synchronize the corresponding second paging packet information in the inactive state to the core network device by sending paging assistance information.

[0231] Optionally, the core network device may first send an indication message to the access network device to indicate whether the access network device is allowed to determine the second paging packet information of the terminal device when it is inactive.

[0232] For example, the core network device can send an indication message to the access network device, instructing the access network device to determine the second paging packet information of the terminal device when it is inactive, and receive the paging assistance information determined by the access network device based on the second paging packet information, thereby determining the second paging packet information corresponding to the inactive state of the terminal device.

[0233] Optionally, the core network device can also instruct the access network device to allocate the second paging packet information for the inactive state to the terminal device by not sending indication information to the access network device. Correspondingly, the access network device can determine the second paging packet information for the terminal device in the inactive state based on protocol agreements or configuration information, even without receiving indication information from the core network device, and synchronize the corresponding second paging packet information for the inactive state to the core network device by sending paging assistance information.

[0234] Step 72: Update the first paging packet information of the terminal device in the idle state according to the paging assistance information.

[0235] Optionally, the first paging packet information may be any one or more of the following: paging packet identifier, paging probability, paging probability indication, and paging cycle.

[0236] The paging packet identifier can be the packet identifier that the core network device determines when the terminal device is in an idle state. The core network device can send a paging message to the terminal device based on the paging packet identifier.

[0237] Among them, the paging probability can be the probability determined by the core network equipment that a terminal device is paging when it is in an idle state.

[0238] The paging probability indicator can be a probability indicator determined by the core network equipment of being paged when the terminal device is in an idle state. The paging probability indicator can be high, medium, or low.

[0239] The paging period can be defined as the interval between two consecutive paging messages sent to a terminal device when the terminal device is in an idle state, as determined by the core network equipment.

[0240] Therefore, in this embodiment of the present disclosure, the core network device determines the first paging packet information of the terminal device in the idle state based on the paging assistance information sent by the access network device. This enables the network side to accurately determine the second paging packet information of the terminal device in the inactive state based on the first paging packet information and the paging assistance information of the terminal device, even if the context information of the terminal device is lost, and to accurately paging the terminal device. This not only improves the paging success rate, but also reduces the power consumption of the terminal during the paging process.

[0241] By implementing the embodiments of this disclosure, the core network device receives paging assistance information corresponding to the terminal device sent by the access network device, and then updates the first paging packet information of the terminal device in the idle state according to the paging assistance information. This ensures that the core network device and the access network device have a consistent understanding of the paging information of the terminal device regardless of whether the terminal device is in an inactive or idle state, thereby reducing the probability of paging failure and reducing the power consumption of the terminal device.

[0242] Please see Figure 8 , Figure 8 This is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by a core network device. Figure 8 As shown, the method may include, but is not limited to, the following steps:

[0243] Step 81: Determine the first paging packet information of the terminal device in the idle state.

[0244] Optionally, the first paging packet information may be assigned by the core network equipment to the terminal equipment. That is, it may be determined by the core network equipment based on protocol agreements.

[0245] Alternatively, the first paging packet information can be allocated by the access network device to the terminal device and then synchronized to the access network device. That is, the first paging packet information can be received by the core network device from the access network device.

[0246] Step 82: Receive paging assistance information corresponding to the terminal device sent by the access network device.

[0247] Step 83: Update the first paging packet information of the terminal device in the idle state according to the paging assistance information.

[0248] The specific implementation of steps 82 and 83 can be found in the detailed descriptions of other embodiments of this disclosure, and will not be repeated here.

[0249] Therefore, in this embodiment of the present disclosure, the core network device determines the first paging packet information of the terminal device in the idle state based on the paging assistance information sent by the access network device. This enables the network side to accurately determine the second paging packet information of the terminal device in the inactive state based on the first paging packet information and the paging assistance information of the terminal device, even if the context information of the terminal device is lost, and to accurately paging the terminal device. This not only improves the paging success rate, but also reduces the power consumption of the terminal during the paging process.

[0250] By implementing the embodiments of this disclosure, the core network device first determines the first paging packet information of the terminal device in the idle state. Then, upon receiving paging assistance information corresponding to the terminal device from the access network device, it can update the first paging packet information of the terminal device in the idle state based on the paging assistance information. This ensures that the core network device and the access network device have a consistent understanding of the terminal device's paging information regardless of whether the terminal device is in an inactive or idle state, thereby reducing the probability of paging failure and lowering the power consumption of the terminal device.

[0251] Please see Figure 9 , Figure 9 This is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by a core network device. Figure 9 As shown, the method may include, but is not limited to, the following steps:

[0252] Step 91: Based on the protocol agreement, determine the first paging packet information corresponding to the terminal device.

[0253] Step 92: Receive paging assistance information corresponding to the terminal device sent by the access network device.

[0254] Step 93: Determine the second paging group information of the terminal device in the inactive state based on the paging auxiliary information.

[0255] The paging assistance information includes the second paging packet information corresponding to the terminal device in the inactive state, as determined by the access network device.

[0256] Step 94: Use the second paging packet information of the terminal device in the inactive state to overwrite the first paging packet information of the terminal device in the idle state.

[0257] The specific implementation of steps 92-94 above can be found in the detailed descriptions of other embodiments of this disclosure, and will not be repeated here.

[0258] Step 95: Send a paging message to the terminal device, wherein the paging message includes the first paging packet information of the terminal device in the idle state.

[0259] It should be noted that, since the first paging packet information in the idle state may have been updated or overwritten by the second paging packet information, the first paging packet information in the idle state included in the paging message in this disclosure is the second paging packet information corresponding to the active state used to overwrite or replace the idle state paging packet information.

[0260] That is, in one embodiment, the core network device may carry the first paging packet information of idle state paging in the paging message initiated to the idle state terminal device.

[0261] In one embodiment, the core network device may carry second paging packet information in the paging message initiated to an inactive terminal device. It should be noted that this second paging packet information is information that overwrites or updates the original first paging packet information of the idle-state paging.

[0262] In one embodiment, the core network device may carry first paging packet information for idle state paging in the paging message initiated to the inactive terminal device.

[0263] In one embodiment, the core network does not need to distinguish the RRC state of the terminal and will carry the first paging packet information of idle state paging in the paging message initiated to the inactive terminal device.

[0264] Optionally, the core network equipment may include inactive second paging packet information in the paging message initiated to the terminal equipment. That is, the first paging packet information of the idle paging at this time is not updated or overwritten by the second paging packet information.

[0265] In one embodiment, the core network device may carry second paging packet information in the paging message initiated to the idle terminal device.

[0266] In one embodiment, the core network may carry second paging packet information in paging messages initiated to inactive terminal devices.

[0267] In one embodiment, the core network does not need to distinguish the RRC state of the terminal and will carry a second paging packet in the paging message initiated to the inactive terminal device.

[0268] In this disclosure, the core network device uses the second paging packet information corresponding to the terminal device in the inactive state to cover the first paging packet information corresponding to the terminal device in the idle state, so that regardless of whether the terminal device is in the inactive state or the idle state, the access network device and the core network device can use the same paging packet information to send paging messages to it.

[0269] If the network loses the context information of the terminal device, that is, if the network considers the terminal device to be in an idle state while the terminal device is still in an inactive state, the core network can send a paging message to the terminal device based on the second paging packet information. As a result, the access network device will also send a paging message to the terminal device based on the second paging packet information. At this time, the terminal device still listens for paging based on the second paging packet information, thereby avoiding paging failure.

[0270] It should be noted that, since the access network device and the core network device can use the same second paging packet information regardless of whether the terminal device is in an inactive or idle state, the core network device can send a paging message directly to the terminal device without determining the current RRC connection status of the terminal device. Optionally, the paging message may include the second paging packet information corresponding to the terminal device in the inactive state, so that the terminal device can perform paging listening based on the second paging packet information regardless of its state.

[0271] By implementing the embodiments of this disclosure, the core network device first determines the first paging packet information corresponding to the terminal device. Then, after receiving paging assistance information corresponding to the terminal device from the access network device, it updates the first paging packet information of the terminal device in the idle state based on the paging assistance information, and sends a paging message to the terminal device based on the new first paging packet information. Thus, by using the second paging packet information of the terminal device in the active state to overwrite the first paging packet information of the terminal device in the idle state, and paging the terminal device based on the new first paging packet information, the core network device not only improves the probability of successful paging but also reduces the power consumption of the terminal device.

[0272] Please see Figure 10 , Figure 10 This is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by a core network device. Figure 10 As shown, the method may include, but is not limited to, the following steps:

[0273] Step 101: Send a first indication message to the access network device, wherein the first indication message is at least used to indicate whether the access network device is allowed to determine the second paging packet information of the terminal device when it is inactive.

[0274] Optionally, the first instruction information can be any one or more of the following:

[0275] Initial context setup request;

[0276] UE context modification request;

[0277] Handover request; and,

[0278] Path switch request acknowledge.

[0279] Optionally, in this disclosure, the core network device can instruct the access network device to return the second paging packet information of the terminal device in the inactive state through the first indication information, or it can instruct the access network device not to allocate the second paging packet information of the inactive state to the terminal device through the first indication information.

[0280] Optionally, the core network device may also send a first indication message to the access network device, wherein the first indication message is at least used to indicate whether the access network device is allowed to determine paging assistance information.

[0281] Thus, when the access network device receives the first indication information that allows it to determine the paging assistance information, it can determine the paging assistance information and return the determined paging assistance information to the core network device.

[0282] Alternatively, the access network device may determine the paging assistance information and return the determined paging assistance information to the core network device if it does not receive a first indication that it is not allowed to determine the paging assistance information.

[0283] Step 102: Receive second indication information sent by the access network device, wherein the second indication information includes paging assistance information.

[0284] Optionally, if the first indication information indicates that the access network device can allocate the second paging packet information in the inactive state to the terminal device, the access network device can allocate the second paging packet information in the inactive state to the terminal device, determine the paging assistance information based on the allocated second paging packet information, and then return the paging assistance information to the core network device.

[0285] Optionally, the second instruction information may be one or more of the following:

[0286] Radio Resource Control (RRC) inactive transition report;

[0287] The initial context setup response; or,

[0288] UE context modification response;

[0289] UE context modification indication;

[0290] UE context suspend request;

[0291] Retrieve UE information;

[0292] Handover request acknowledgement; and,

[0293] Path switch request.

[0294] Step 103: Determine the second paging packet information corresponding to the terminal device in the inactive state according to the second instruction information.

[0295] Step 104: Use the second paging packet information of the terminal device in the inactive state to overwrite the first paging packet information of the terminal device in the idle state.

[0296] Step 105: Send a paging message to the terminal device, wherein the paging message includes the first paging packet information of the terminal device in the idle state.

[0297] The specific implementation of steps 103-105 above can be found in the detailed descriptions of other embodiments of this disclosure, and will not be repeated here.

[0298] In this disclosure, the core network device uses the second paging packet information corresponding to the terminal device in the inactive state to cover the first paging packet information corresponding to the terminal device in the idle state, so that regardless of whether the terminal device is in the inactive state or the idle state, the access network device and the core network device can use the same second paging packet information to send paging messages to it.

[0299] If the network loses the context information of the terminal device, that is, if the network considers the terminal device to be in an idle state while the terminal device is still in an inactive state, the core network can send a paging message to the terminal device based on the second paging packet information. As a result, the access network device will also send a paging message to the terminal device based on the second paging packet information. At this time, the terminal device still listens for paging based on the second paging packet information, thereby avoiding paging failure.

[0300] By implementing the embodiments of this disclosure, the core network device first sends a first indication message to the access network device. Then, upon receiving a second indication message from the access network device including second paging packet information, the core network device can use the second indication message to overwrite the first paging packet information of the terminal device in the idle state. Thus, by using the second paging packet information of the terminal device in the active state to overwrite the first paging packet information of the terminal device in the idle state, and paging the terminal device based on the new first paging packet information, the core network device not only increases the probability of successful paging but also reduces the power consumption of the terminal device.

[0301] Please see Figure 11 , Figure 11 This is a flowchart illustrating another paging method provided in an embodiment of this disclosure. The method is configured to be executed by a core network device. Figure 11 As shown, the method may include, but is not limited to, the following steps:

[0302] Step 111: Determine the first paging packet information of the terminal device in the idle state.

[0303] Step 112: Receive paging assistance information corresponding to the terminal device sent by the access network device, wherein the paging assistance information is used to assist the core network device in determining the first paging packet information of the terminal device in the idle state.

[0304] Step 113: Update the first group information of the terminal in the idle state according to the paging assistance information.

[0305] Step 114: In response to the terminal device changing from the active state to the idle state, update the first paging packet information corresponding to the terminal device in the idle state.

[0306] Because the paging probability and paging cycle of a terminal device may differ in the inactive and idle states, the power consumed by the terminal device during the paging process also differs between the inactive and idle states. In this disclosure, when the terminal device is in the inactive state, the core network device determines its first paging packet information in the idle state based on its second paging packet information in the inactive state. This ensures that even if the network side loses the context information of the terminal device, paging failure will not occur.

[0307] To minimize the power consumption of terminal devices during the paging process, if the core network device still uses the second paging packet information from the inactive state to page the terminal device after determining that the terminal device has entered the idle state from the active state, it may cause additional power loss. Therefore, the core network device can update the first paging packet information corresponding to the terminal device in the idle state, so that the access network device can send the paging message to the terminal device in the idle state using the new first paging packet information, thereby reducing the power consumption of the terminal device during the paging process.

[0308] Optionally, the core network equipment can update the first paging packet information corresponding to the terminal equipment in the idle state based on the first paging packet information sent by the access network equipment.

[0309] That is, the first paging packet information corresponding to the terminal device in the idle state is determined and updated by the access network device, and then the core network device receives the first paging packet information sent by the access network device.

[0310] Optionally, the core network equipment can also update the first paging packet information corresponding to the terminal equipment in the idle state according to the protocol.

[0311] That is, the core network equipment determines the first paging packet information of the terminal equipment in the idle state according to the protocol, and overwrites the previous first paging packet information with the new paging packet information.

[0312] By implementing the embodiments of this disclosure, in response to the terminal device entering the idle state from the active state, the core network device updates the first paging packet information corresponding to the terminal device in the idle state. Thus, when the terminal device enters the idle state from the active state, both the access network device and the core network device send a paging message to the terminal device in the idle state using the updated first paging packet information. The terminal device also uses the updated first paging packet information for paging listening, which not only increases the probability of successful paging but also reduces the power consumption of the terminal device.

[0313] Based on the above analysis, in this disclosure, the access network device first sends paging assistance information for the inactive terminal device to the core network, which is used by the core network device to send paging messages for the terminal device.

[0314] Optionally, the paging assistance information includes one of the following:

[0315] The second paging packet information in the inactive state assigned by the access network device to the terminal device is used by the terminal device to determine the packet it is listening to when listening to the paging signal in the inactive state.

[0316] As one embodiment, the second paging packet information provided or allocated by the access network device may be a specific GroupingID.

[0317] As one embodiment, the second paging packet information provided or allocated by the access network device is the paging probability.

[0318] As one embodiment, the paging packet information provided or allocated by the access network device is a paging probability indicator, such as high, medium, or low.

[0319] As one embodiment, the paging packet information provided or allocated by the access network device is the paging cycle.

[0320] As one embodiment, the paging probability of the terminal estimated by the access network device is used as a reference for the second paging packet information when the core network device allocates the inactive state to the terminal device;

[0321] Optionally, whether the access network device allows the allocation of second paging packet information or other auxiliary information to inactive users can be based on the core network configuration or protocol agreement.

[0322] As one embodiment, the core network device may carry this instruction in the following message.

[0323] Initial context setup request;

[0324] UE context modification request;

[0325] Handover request; and,

[0326] Path switch request acknowledge.

[0327] In summary, core network devices can carry this instruction not only through the messages mentioned above, but also by adding new messages.

[0328] As one example: if the core network device does not send an indication, the access network device will not process it. For example, the access network device may use the same set of parameters for the idle state and the inactive state.

[0329] As one example: if the core network device does not send an instruction, the access network device may process it as permitted.

[0330] Optionally, after allocating the second paging packet information and / or other auxiliary information for inactive paging to the terminal device, the access network device may notify the core network device in the following information:

[0331] Radio Resource Control (RRC) inactive transition report;

[0332] The initial context setup response; or,

[0333] UE context modification response;

[0334] UE context modification indication;

[0335] UE context suspend request;

[0336] Retrieve UE information;

[0337] Handover request acknowledgement; and,

[0338] Path switch request.

[0339] As one example, the base station can carry this auxiliary information based on the newly added message.

[0340] Optionally, after receiving the second paging packet information allocated by the access network device for inactive paging of the terminal device, the core network device may use the second paging packet information to overwrite the first paging packet information allocated for idle paging of the terminal user.

[0341] Among them, the network element that allocates the first paging packet information for idle-state paging to the end user may be an access network device. In this case, the access network device can pass the information to the core network device through inter-interface messages for storage.

[0342] Alternatively, the network element that allocates the first paging packet information for idle-state paging to the terminal device may be a core network device. In this case, the core network device may need to base its paging assistance information on the paging assistance information provided by the access network device, which will be transmitted to the core network device through inter-interface messages.

[0343] Optionally, if the network element that allocates the second paging packet information for inactive paging to the terminal device is a core network device, the core network device can allocate the second paging packet information for inactive paging to the terminal device based on the paging assistance information provided by the access network device.

[0344] For example, the calculation of the second paging packet information allocated by the core network will be based on the paging assistance information provided by the access network equipment. For instance, the second paging packet information calculated by the core network is determined based on the paging probability provided by the access network equipment.

[0345] Optionally, if the network element that allocates the second paging packet information for inactive paging to the terminal device is a core network device, the core network device can use the second paging packet information to overwrite the first paging packet information allocated to the terminal device for idle paging.

[0346] Optionally, the core network device may include the first paging packet information for idle-state paging in the paging message initiated to the terminal device. It should be noted that the first paging packet information for idle-state paging may have been updated or overwritten by the second paging packet information at this time.

[0347] That is, in one embodiment, the core network device may carry the first paging packet information of idle state paging in the paging message initiated to the idle state terminal device.

[0348] In one embodiment, the core network may carry second paging packet information in paging messages initiated to inactive terminal devices. It should be noted that this second paging packet information overwrites or updates the original first paging packet information from idle-state paging.

[0349] In one embodiment, the core network device may carry first paging packet information for idle state paging in the paging message initiated to the inactive terminal device.

[0350] In one embodiment, the core network does not need to distinguish the RRC state of the terminal and will carry the first paging packet information of idle state paging in the paging message initiated to the inactive terminal device.

[0351] Optionally, the core network equipment may include inactive second paging packet information in the paging message initiated to the terminal equipment. That is, the first paging packet information of the idle paging at this time is not updated or overwritten by the second paging packet information.

[0352] In one embodiment, the core network device may carry second paging packet information in the paging message initiated to the idle terminal device.

[0353] In one embodiment, the core network may carry second paging packet information in paging messages initiated to inactive terminal devices.

[0354] In one embodiment, the core network does not need to distinguish the RRC state of the terminal and will carry a second paging packet in the paging message initiated to the inactive terminal device.

[0355] Optionally, after receiving the second paging packet information for inactive paging, the inactive terminal device will use the second paging packet information to simultaneously listen for paging messages from both the core network device and the access network device.

[0356] Optionally, when the terminal device re-enters the idle state from the inactive state, it can obtain updated first paging packet information for idle state paging.

[0357] In one possible implementation, if the access network device allocates the first paging packet information to the terminal device, then when the terminal device re-enters the idle state from the inactive state, the access network device will allocate the first paging auxiliary information for idle state paging.

[0358] In a preferred embodiment, when the access network device notifies the terminal device to enter the idle state via an RRC message (such as RRC Release), it will simultaneously allocate first paging assistance information for idle state paging.

[0359] In another possible implementation, the core network device allocates the first paging packet information to the terminal device. When the core network device determines that the terminal device has re-entered the idle state from the inactive state, it will reallocate the first paging packet information to the terminal device. In this case, the access network device can obtain the first paging auxiliary information for idle-state paging through signaling interactions with the core network device, such as through a terminal context release command message sent by the core network device.

[0360] At this point, after the terminal device re-enters the idle state from the inactive state, it can re-attach. This behavior can be based on protocol agreements or on instructions received from the network (such as RRRCRelease).

[0361] Alternatively, when a terminal device re-enters the idle state from an inactive state, it will do so through signaling interaction with the core network device. This could involve the core network device, upon receiving a release request from the access network device, reallocating the first paging packet information to the terminal device about to enter the idle state. It is understandable that the core network device can reallocate a new first paging packet information to the terminal device before it is released.

[0362] Core network devices can first pass the newly allocated first paging packet information to the access network devices, which then pass it to the terminal devices.
