Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a method, device, and apparatus for transmitting device information through an interface. Background Art

[0002] Paging refers to the process of searching for a terminal initiated by a network device. Paging can establish a connection between the network device and the terminal, thereby enabling communication between the network device and the terminal.

[0003] In current technologies, network devices typically perform paging of terminals at the granularity of Tracking Areas (TAs). However, for passive terminals, due to their low functionality, passive reflected signal communication is typically used. This prevents timely notification of changes in the TA of a passive terminal to the network device, making current paging methods incapable of achieving communication with passive terminals. Therefore, there is an urgent need to provide a method for enabling communication between network devices and passive terminals. Summary of the Invention

[0540] To make the objectives, technical solutions, and advantages of this application more clear, the technical solutions in this application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0541] To further reduce environmental impact, the industry is increasingly looking to use passive devices for product registration, tracking, and management. Furthermore, they hope to enable these passive devices to achieve corresponding control functions through the 3rd Generation Partnership Project (3GPP) network. Consequently, passive IoT devices have emerged.

[0542] Passive IoT devices do not require batteries and can draw energy from the surrounding environment. At the same time, they can meet the function of accessing the Internet instead of being managed through a local area network.

[0543] Passive IoT devices have lower functionality, supporting energy harvesting and storage, and carrying their own information by reflecting downlink carrier waves. Optionally, they may also generate and transmit signals using their own RF components. Passive IoT devices may also be referred to as passive terminals, passive terminal devices, and so on.

[0544] The number of IoT devices based on cellular network positioning will continue to increase. However, due to the high power consumption of traditional IoT devices, the maintenance costs of these devices due to batteries are also high. Therefore, the introduction of passive IoT devices without battery storage can not only reduce device power consumption, but also significantly reduce maintenance costs.

[0545] In practice, there is a need for terminals to communicate with access network equipment. Currently, core network equipment generally performs terminal paging at the TA granularity, establishing a connection between the access network equipment and the terminal through paging, thereby enabling communication between the access network equipment and the terminal.

[0546] For passive IoT devices, the TA-based paging mechanism can continue to be used. However, since most passive IoT devices use passive reflected signal communication, the core network device cannot be notified promptly when the TA of a passive IoT terminal device changes. Therefore, the current paging method may not be able to page the terminal. Secondly, ordinary terminals can enter a connected state and continuously receive data, but for passive IoT devices, a connected state may not exist, so paging is required before each data transmission. Finally, for application scenarios of passive IoT devices, such as inventory counting, it is necessary to count the large number of passive IoT terminal devices in the warehouse, which cannot be supported by the current paging method.

[0547] Based on this, an embodiment of the present application provides a method for transmitting device information via an interface to achieve communication between a network device and a passive terminal. The solution of the embodiment of the present application will be described below with reference to the accompanying drawings.

The number of target terminals can be one or more, and this embodiment of the application is not limited to this.

[0573] 2.1a. Terminal identification information, used to indicate at least one terminal.

[0574] Terminal identification information is information related to the terminal's identity. It can be the terminal's identity itself or characteristic information indicating the terminal's identity. Because the terminal's identity uniquely identifies the corresponding terminal, the access network device can use the terminal's identity information to determine the terminal identified by the terminal's identity information and use it as the target terminal.

[0575] In a possible implementation, the terminal identification information includes at least one of the following: terminal identification, range information of the terminal identification, characteristic information of the terminal identification, mask information of the terminal identification, and bit identification information of the terminal identification.

[0576] The core network device may send one or more terminal identifiers to the access network device, where the one or more terminal identifiers are used to indicate the corresponding one or more terminals.

[0577] The core network device can send terminal identifier range information to the access network device. The terminal identifier range information is used to indicate the range of the terminal identifier. The terminal identifier range can be used to determine the terminals whose terminal identifiers fall within the range, i.e., the at least one terminal indicated by the terminal identifier information. The terminal identifier range information can contain one or more terminals. For any terminal identifier range, the number of terminals whose terminal identifiers fall within the range can also be one or more terminals.

[0578] The core network device may send characteristic information of the terminal identification to the access network device. The characteristic information of the terminal identification may include, for example, a characteristic identifier of the terminal identification. The terminal including the characteristic identifier may be determined as the terminal indicated by the terminal identification information.

[0579] Core network equipment can send terminal identification mask information to access network equipment. This terminal identification mask information is the information obtained by partially masking the terminal identification. For example, if the terminal identification has m1 bits, n1 bits (where n1 is less than m1) of the m1 bits can be masked to obtain the terminal identification mask information. For any terminal, if the terminal identification satisfies the remaining m1-n1 bits after removing the mask from the m1 bit, the terminal can be determined as the terminal indicated by the terminal identification information.

[0580] The core network device can send the bit identification information of the terminal identifier to the access network device to indicate several bits of the terminal identifier. For example, the bit identification information of the terminal identifier can indicate the first k bits of the terminal identifier, can indicate the last k bits of the terminal identifier, or can indicate any k bits of the terminal identifier, and the embodiments of the present application do not limit this. For any terminal, if the corresponding several bits of the terminal are the same as the data of the several bits indicated by the bit identification information of the terminal identifier, it can be determined as the terminal indicated by the terminal identification information; if the corresponding several bits of the terminal are different from the data of the several bits indicated by the bit identification information of the terminal identifier, it is not determined as the terminal indicated by the terminal identification information.

[0581] 2.1b. Terminal group identification information, used to indicate at least one terminal group.

[0582] Terminal group identification information is information related to the terminal group identification, and can be the terminal group identification itself or characteristic information indicating the terminal group identification. Because the terminal group identification uniquely identifies the corresponding terminal group, the terminal group identification information allows the access network device to determine the terminal group identified by the terminal group identification information and use the terminals in the terminal group as target terminals.

[0583] In a possible implementation, the terminal group identification information includes at least one of the following: the terminal group identification, range information of the terminal group identification, characteristic information of the terminal group identification, mask information of the terminal group identification, and bit identification information of the terminal group identification.

[0584] The core network device may send one or more terminal group identifiers to the access network device, where the one or more terminal group identifiers are used to indicate the corresponding one or more terminal groups.

[0585] The core network device may send terminal group identifier range information to the access network device. The terminal group identifier range information is used to indicate the range of the terminal group identifier. The terminal group identifier range can be used to determine the terminal groups whose terminal group identifiers fall within the range of the terminal group identifier, i.e., the at least one terminal group indicated by the terminal group identifier information. The terminal group identifier range information may include one or more terminal groups. For any terminal group identifier range, the number of terminal groups whose terminal group identifiers fall within the range of the terminal group identifier may also be one or more.

[0586] The core network device may send characteristic information of the terminal group identifier to the access network device. The characteristic information of the terminal group identifier may include, for example, a characteristic identifier of the terminal group identifier. The terminal group including the characteristic identifier may be determined as the terminal group indicated by the terminal group identifier information.

[0587] The core network device can send mask information for the terminal group identifier to the access network device. This mask information is the information obtained by partially masking the terminal group identifier. For example, if the terminal group identifier has m2 bits, n2 bits (where n2 is less than m2) of the m2 bits can be masked to obtain the mask information for the terminal group identifier. For any terminal group, if the terminal group identifier of that terminal group satisfies the remaining m2-n2 bits after removing the mask from the m2 bits, the terminal group can be determined as the terminal group indicated by the terminal group identifier information.

[0588] The core network device can send the bit identification information of the terminal group identifier to the access network device to indicate several bits of the terminal group identifier. For example, the bit identification information of the terminal group identifier can indicate the first d bits of the terminal group identifier, can indicate the last d bits of the terminal group identifier, or can indicate any d bits of the terminal group identifier, and the embodiments of the present application do not limit this. For any terminal group, if the corresponding several bits of the terminal group are the same as the data of the several bits indicated by the bit identification information of the terminal group identifier, it can be determined as the terminal group indicated by the terminal group identification information; if the corresponding several bits of the terminal group are different from the data of the several bits indicated by the bit identification information of the terminal group identifier, it is not determined as the terminal group indicated by the terminal group identification information.

[0589] 2.1c. Terminal attribute information, used to indicate at least one target terminal attribute.

[0590] The terminal attribute identifier may include an attribute group identifier, and the attribute group identifier is used to indicate at least one of the following: terminal function attribute, terminal location attribute, terminal process attribute, and terminal usage attribute.

[0591] Terminal function attributes identify the terminal's function, terminal location attributes identify the terminal's location, terminal process attributes identify the terminal's processing flow, and terminal usage attributes identify the terminal's purpose. Target terminal attributes may include at least one of the following: terminal function attributes, terminal location attributes, terminal process attributes, and terminal usage attributes. Target terminal attributes can be indicated by an attribute group identifier. Any terminal that possesses the target terminal attributes indicated by the attribute group identifier can be selected as a target terminal.

[0592] 2.1d. Paging range information, used to indicate the paging range.

[0593] The paging range information includes at least one of the following: cell list information, relay device list information, and tracking area list information.

[0594] The cell list information may include information of one or more cells, for indicating the one or more cells. In the case where the paging range information includes the cell list information, the paging range indicated by the paging range information includes the coverage of the one or more cells.

[0595] Optionally, the cell list information may also include beam list information. For one or more cells indicated by the cell list information, the beam list information may be used to indicate beam range information within the one or more cells. Accordingly, the paging range indicated by the paging range information includes the coverage of one or more beams under the one or more cells.

[0596] The relay device list information may include information of one or more relay devices, used to indicate these one or more relay devices. The information of these one or more relay devices may, for example, include device identifications of one or more relay devices, for example, may include identifications of terminals to be paged by each relay device, and so on.

[0597] The tracking area list information is used to indicate one or more tracking areas, and the paging range indicated by the paging range information includes the one or more tracking areas.

[0598] 2.1e, Identification bit, used to indicate paging all terminals within the paging range.

[0599] If the terminal indication information includes an identification bit, it can be determined based on the terminal indication information that all terminals within the paging range need to be paged.

[0600] A target terminal for communicating with the access network device may be determined based on the terminal indication information, where the target terminal includes any one of the following:

[0601] at least one terminal indicated by the terminal identification information;

[0602] terminals included in at least one terminal group indicated by the terminal group identification information;

[0603] at least one terminal having target terminal attributes indicated by the terminal attribute information;

[0604] Terminals within the paging range indicated by the paging range information.

[0605] For example, when the terminal indication information includes terminal identification information, the target terminal includes at least one terminal indicated by the terminal identification information; when the terminal indication information includes terminal group identification information, the target terminal includes terminals included in at least one terminal group indicated by the terminal group identification information; when the terminal indication information includes terminal attribute information, the target terminal includes at least one terminal with target terminal attributes indicated by the terminal attribute information; when the terminal indication information includes paging range information and / or identification bits, the target terminal includes terminals within the paging range indicated by the paging range information.

[0606] The following describes how to determine the target terminal when the terminal indication information includes different information using a specific example.

[0607] In a possible implementation, take the case where the terminal indication information includes an identification bit as an example.

[0608] If the terminal indication information includes an identification bit, the terminal indication information indicates paging all terminals, that is, the target terminals include all terminals;

[0609] If the terminal indication information includes a flag bit and terminal identification information, the terminal indication information indicates at least one terminal indicated by the paging terminal identification information, that is, the target terminal includes at least one terminal indicated by the terminal identification information;

[0610] If the terminal indication information includes an identification bit and terminal group identification information, the terminal indication information indicates paging terminals in at least one terminal group indicated by the terminal group identification information, that is, the target terminal includes terminals included in at least one terminal group indicated by the terminal group identification information;

[0611] If the terminal indication information includes an identification bit and terminal attribute information, the terminal indication information indicates paging at least one terminal having target terminal attributes indicated by the terminal attribute information, that is, the target terminal includes at least one terminal having target terminal attributes indicated by the terminal attribute information;

[0612] If the terminal indication information includes an identification bit and terminal attribute information, the terminal indication information indicates terminals within the paging range indicated by the paging range information, that is, the target terminals include terminals within the paging range indicated by the paging range information;

[0613] If the terminal indication information includes an identification bit and also includes at least two of the following: terminal identification information, terminal group identification information, terminal attribute information, paging range information, and terminal attribute information, then the terminal indication information indicates that all terminals that meet the requirements should be paged. For example, if the terminal indication information includes an identification bit, terminal identification information, and terminal group identification information, and the terminal identification information indicates terminal A and the terminal group identification information indicates terminal group B, then the terminal indication information indicates that terminal A and all terminals in terminal group B should be paged.

[0614] In a possible implementation, take the case where the terminal indication information does not include an identification bit as an example.

[0615] If the terminal indication information does not include an identification bit, the terminal indication information indicates paging all terminals, that is, the target terminals include all terminals;

[0616] If the terminal indication information does not include an identification bit, and the terminal indication information includes terminal identification information, then the terminal indication information indicates at least one terminal indicated by the paging terminal identification information, that is, the target terminal includes at least one terminal indicated by the terminal identification information;

[0617] If the terminal indication information does not include an identification bit, and the terminal indication information includes terminal group identification information, the terminal indication information indicates paging terminals in at least one terminal group indicated by the terminal group identification information, that is, the target terminal includes the terminals included in the at least one terminal group indicated by the terminal group identification information;

[0618] If the terminal indication information does not include an identification bit and the terminal indication information includes terminal attribute information, the terminal indication information indicates paging at least one terminal having target terminal attributes indicated by the terminal attribute information, that is, the target terminal includes at least one terminal having target terminal attributes indicated by the terminal attribute information;

[0619] If the terminal indication information does not include an identification bit and includes terminal attribute information, the terminal indication information indicates terminals within the paging range indicated by the paging range information, that is, the target terminals include terminals within the paging range indicated by the paging range information;

[0620] If the terminal indication information does not include an identification bit and includes at least two of the following: terminal identification information, terminal group identification information, terminal attribute information, paging range information, and terminal attribute information, then the terminal indication information instructs paging of all terminals that meet the requirements. For example, if the terminal indication information does not include an identification bit and includes both terminal identification information and terminal group identification information, and the terminal identification information indicates terminal A and the terminal group identification information indicates terminal group B, then the terminal indication information instructs paging of all terminals in terminal A and terminal group B.

[0621] 2.2. Terminal command information, used to instruct the terminal to perform a first operation.

[0622] The first operation includes at least one of the following: reporting terminal identification information, reporting confirmation information, obtaining specified information in the terminal memory, performing a write operation, and obtaining sensor information of the terminal.

[0623] The terminal command information is used to instruct the terminal to perform the first operation. Therefore, when the device indication information includes the terminal command information, the access network device can send the terminal command information to the target terminal to instruct the target terminal to perform the first operation.

[0624] Among them, with respect to reporting terminal identification information, the target terminal can send its own terminal identification to the access network device, which is then sent to the core network device. With respect to reporting confirmation information, the target terminal can indicate that the target terminal has been connected by replying ACK. With respect to obtaining specified information in the terminal memory, the target terminal can obtain the specified information in its own memory based on the instructions of the terminal command information. The target terminal can choose to report the specified information to the access network device or not. With respect to performing a write operation, the target terminal can perform a write operation and write the corresponding data. With respect to obtaining sensor information of the terminal, the target terminal can obtain sensor information. For example, with respect to a temperature sensor, the ambient temperature can be obtained; with respect to a humidity sensor, the ambient humidity can be obtained, and so on.

[0625] After executing the first operation, the terminal may or may not feed back the result of the first operation to the access network device. This embodiment of the present application does not limit this.

[0626] 2.3. Terminal command information index, used to indicate terminal command information.

[0627] The terminal command information index is used to indicate the terminal command information. The target terminal can determine the terminal command information based on the terminal command information index, and thus perform the first operation based on the terminal command information. The process of the target terminal performing the first operation can be referred to the relevant introduction of 2.2, which will not be repeated here.

[0628] 2.4. Terminal context information, used to indicate the terminal context.

[0629] To facilitate paging of a terminal by an access network device, the core network device may include terminal context information in the device indication information sent to the access network device to indicate the terminal context. The terminal context information includes at least one of the following: terminal configuration information, terminal security configuration information, the terminal group to which the terminal belongs, and the terminal group attributes.

[0630] The terminal configuration information includes the terminal's current time-frequency domain resource configuration information and / or the uplink NG interface service plane transport network layer (TNL) information. The terminal security configuration information may include whether the current terminal has security encryption enabled, the security algorithms supported by the terminal, the security algorithms configured by the terminal, the algorithm key parameters used by the access network device, etc. The terminal group to which the terminal belongs is the association between the terminal identifier and the terminal group identifier. For example: the terminal belongs to a certain terminal group, and the attributes of the terminal group are mainly the association between the terminal identifier and the attributes of the terminal group, that is, the attributes of the terminal group corresponding to the terminal.

[0631] 2.5. Resource grouping information is used to indicate the air interface resources of the terminal.

[0632] In the case of paging multiple terminals or unspecified terminals to be paged, the core network equipment can estimate the approximate number of terminals and indicate the division of air interface resources. Divide the air interface resources according to the number of resource groups to enable paging and access of multiple terminals. Resource grouping information may include the number of groups and / or group indexes. The number of groups indicates the number of resource groups obtained by dividing the air interface resources, and the group index is used to indicate each resource group. Different resource groups have different air interface resources. The number of groups and the group index indicate that the core network recommends that the terminal information indicated by the group number index be reported first according to the default algorithm based on the grouping suggestion.

[0633] 2.6. Access network device command information, used to instruct the access network device to perform a second operation.

[0634] The access network device command information is used to instruct the access network device to perform the second operation. Therefore, when the device indication information includes the access network device command information, the access network device can perform the second operation based on the access network device command information.

[0635] The second operation includes at least one of the following: positioning the terminal, measuring the terminal, supplying power to the terminal, and sending an excitation signal to the terminal.

[0636] When the second operation includes locating the terminal, the positioning function requires the access network device to obtain further positioning information. Optionally, the core network device may send positioning configuration information to the access network device. The positioning configuration information may include, for example, the required accuracy for positioning the terminal. The positioning configuration information may or may not be included in the device indication information.

[0637] When the second operation includes measuring the terminal, the measurement information instructs the access network device to obtain the measurement result of the terminal. Optionally, the core network device may send measurement configuration information to the access network device, and the measurement configuration information may include at least one of a received signal strength indication (RSSI) measurement result, a signal to interference plus noise ratio (SINR) measurement result, a reference signal receiving quality (RSRQ) measurement result, and a reference signal receiving power (RSRP) measurement result.

[0638] When the second operation includes powering the terminal, the access network device transmits a power supply signal to the terminal within the specified range to provide power.

The power supply configuration information may include at least one of the following information: a power supply signal transmission period, a power supply signal transmission frequency, a power supply signal transmission count, and a power supply signal transmission duration.

[0639] When the second operation includes sending an excitation signal to the terminal, the access network device sends the excitation signal within a certain range. The excitation signal may also carry corresponding excitation configuration information, for example, at least one of the following information: the period of sending the excitation signal, the frequency of sending the excitation signal, the number of times the excitation signal is sent, the length of time for sending the excitation signal, etc.

[0640] 2.7. Paging performance indicator information is used to indicate the paging performance requirement indicator.

[0641] The paging performance requirement indicators may include, for example, the time limit for paging completion. The time limit may be the time limit for paging completion for a single terminal, the time limit for paging completion for a terminal group, the time limit for paging completion for a resource group, or the time limit for the access network device to complete the paging triggered by the core network device at the interface.

[0642] 2.8. Paging priority information, used to indicate the paging priority of the terminal.

[0643] The paging priority information is used to indicate the priority of the paging terminal. The terminal with a higher paging priority is paged earlier, and the terminal with a lower paging priority is paged later.

[0644] 2.9. Paging reason information, used to indicate the paging reason.

[0645] The paging reason information indicates the reason why the terminal is paged. The paging reason includes at least one of the following: device termination (Device-terminated, DT), device-originated device-terminated triggered (Device-Originated Device-Terminated Triggered, DO-DTT), sending an excitation signal to the terminal, terminal inventory, terminal positioning, reading operation on the terminal, and writing operation on the terminal.

[0646] 2.10. Terminal capability information, used to indicate terminal capabilities.

[0647] The terminal capability information is used to indicate at least one of the following: the type of the terminal, whether the terminal is allowed to trigger uplink transmission, whether the terminal is allowed to store energy, the maximum transmit power of the terminal, the coding and modulation modes supported by the terminal, and the frequency range supported by the terminal.

[0648] In the above embodiment, the content included in the device indication information is introduced. After receiving the device indication information, the access network device can perform a paging operation or an access operation for the target terminal based on the device indication information.

[0649] In one possible implementation, there may be a target terminal access collision and / or a situation where terminal omissions are avoided. Target terminal access collision refers to a situation where there are multiple target terminals and a conflict occurs during their access to an access network device. Terminal omission refers to a situation where a target terminal fails to access an access network device.

[0650] To reduce target terminal access collisions and / or terminal statistics omissions, the core network device may send access mode indication information to the access network device. The access mode indication information is used to indicate the access mode of the target terminal. After receiving the access mode indication information sent by the core network device, the access network device determines the access mode of the target terminal based on the access mode indication information.

[0651] The access method includes at least one of the following items 3.1 to 3.4:

[0652] 3.1. Based on multiple rounds of device indication information sent by the core network device, perform a paging operation or access operation for the target terminal.

[0653] If the access mode indication information indicates that the access mode is to perform a paging operation or access operation for a target terminal based on multiple rounds of device indication information sent by a core network device, the core network device may send multiple rounds of device indication information to the access network device to instruct the access network device to establish communication with the target terminal through multiple rounds of paging operations or multiple rounds of access operations until all target terminals to be accessed have completed access. Performing paging operations or access operations for target terminals through multiple rounds of device indication information can reduce the possibility of terminal access collisions and avoid terminal statistics or inventory omissions.

[0654] 3.2. Instruct the connected target terminal to enter the silent state.

[0655] The access mode indication information may include a silence duration, which indicates the duration for which an already connected target terminal enters a silent state. If the access mode indication information indicates that the access mode includes the already connected target terminal entering a silent state, the already connected target terminal will enter a silent state for a duration indicated by the silence duration. By instructing an already connected target terminal to enter a silent state, the already connected target terminal can be prevented from influencing or interfering with other terminals, thereby reducing the possibility of terminal access collisions.

[0656] 3.3. Based on the binary tree algorithm access control method or the ALOHA algorithm (an anti-collision algorithm), a paging operation or an access operation is performed on the target terminal.

[0657] The indication information sent by the core network device to the access network device includes a resource access index, instructing the access network device to complete terminal access corresponding to the specified resource index. If multiple terminals access the resource index, a binary tree access control method or an ALOHA access control method is used. Optionally, the core network device can instruct the access network device to use an access control algorithm such as the binary tree algorithm or the ALOHA algorithm.

[0658] 3.4. Execute paging or access operations for target terminals in a resource grouping manner.

[0659] Optionally, the access mode indication information sent by the core network device to the access network device includes group indication information, which is used to indicate the grouping information of the access network device and terminal resources. Based on the grouping information, the access network device performs paging operations or access operations for the target terminal in a resource grouping manner.

[0660] Optionally, the grouping indication information includes at least one of the following: the level of resource grouping, time length information of resource grouping at each level, and frequency bandwidth information of resource grouping at each level.

[0661] The solution based on resource grouping means that when there is a terminal access collision within the group, the access network equipment can coordinate the terminal access within the group by continuing the secondary grouping within the group and dividing multiple resources.

[0662] For example, resource grouping levels include primary and secondary. The primary level indicates a primary grouping of air interface resources, with the grouping indication information indicating the time length and / or frequency bandwidth information of the primary resource grouping. The secondary level indicates a secondary grouping of each group within the primary resource grouping, with the grouping indication information indicating the number of secondary groups, the time length and / or frequency bandwidth information of the secondary resource grouping, and the number of secondary groups indicating the number of groups each group within the primary resource grouping is further divided into.

[0663] In the above embodiments, several different access methods are introduced. It should be noted that the above-mentioned different access methods can be used individually or in combination. For example, a paging operation or access operation for the target terminal can be performed based on multiple rounds of device indication information sent by the core network device, and the target terminal that has been connected can be set to enter a silent state; for example, a paging operation or access operation for the target terminal can be performed based on multiple rounds of device indication information sent by the core network device, wherein multiple target terminals can be accessed using a binary tree algorithm; for example, a paging operation or access operation for the target terminal can be performed based on resource grouping, and the target terminal that has been connected can be set to enter a silent state, and so on. The above-mentioned access methods can be used in any combination, and the embodiments of the present application will not be illustrated one by one here.

[0664] After receiving the device indication information, the access network device performs a paging operation or an access operation for the target terminal.

[0665] In one possible implementation, an access network device may perform a paging operation or an access operation for a target terminal through a relay device. Specifically, the access network device transmits device indication information to the relay device, where the device indication information instructs the relay device to transmit a first downlink signal to the target terminal, where the first downlink signal includes the device indication information. The relay device performs the paging operation or the access operation for the target terminal using the first downlink signal.

[0666] In a possible implementation, the access network device may send a second downlink signal to the target terminal, where the second downlink signal includes the device indication information, and the access network device performs a paging operation or an access operation for the target terminal through the second downlink signal.

[0667] Optionally, after the access network device performs a paging operation or an access operation on the target terminal and establishes a connection with the target terminal, the access network device sends terminal command information to the target terminal, where the terminal command information is used to instruct the target terminal to perform the first operation. Optionally, the terminal command information may be carried in a first downlink signal, such as a paging message. Optionally, after the access network device establishes a connection with the target terminal via the first downlink signal, the access network device further sends the terminal command information to the target terminal. The contents of the first operation can be found in the relevant description of the above embodiment and are not further described here.

[0668] Optionally, after receiving the access network device command information, the access network device performs a second operation based on the access network device command information. The content of the second operation can be found in the relevant introduction of the above embodiment and will not be repeated here.

[0669] After the target terminal performs the first operation, the corresponding operation result can be fed back to the access network device, and the access network device sends the operation result of the first operation to the core network device. After the access network device performs the second operation, the access network device can feed back the corresponding operation result to the core network device.

[0670] Specifically, the access network device may send a response message to the core network device to feedback the corresponding operation result. The response message includes at least one of the following 4.1 to 4.7:

For example, it may include at least one of the following: information about the cell where the target terminal is located, signals related to the relay device corresponding to the target terminal, TA information, etc. Optionally, more detailed location information may be further indicated based on the instructions of the positioning command, such as direction angle, distance from the access network device, beam information, etc.

[0677] 4.4. Measurement results of the target terminal.

[0678] The core network device can configure measurement configuration information and send it to the access network device. The access network device instructs the target terminal to perform corresponding measurements based on the measurement configuration information, and the target terminal sends the measurement results to the access network device. The access network device then sends the measurement results of the target terminal to the core network device.

[0679] 4.5. Operation results of terminal command information.

[0680] The operation result of the terminal command information is used to indicate whether the target terminal completes the first operation according to the instruction of the terminal command information.

[0681] 4.6. Operation results of access network device command information.

[0682] The operation result of the access network device command information is used to indicate whether the access network device completes the second operation according to the instruction of the access network device command information.

[0683] 4.7. TNL information of the service plane of the downlink NG interface of the access network equipment.

[0684] The TNL information of the downlink NG interface service plane of the access network device is used to indicate TNL information, thereby indicating the subsequent data transmission between the access network device and the terminal.

[0685] In one possible implementation, the response information belongs to the second service data of the service plane, or the response information is carried in a second NG interface control plane message. The core network device can send the response information directly to the access network device, or carry it in a second NG interface control plane message and send it to the access network device. The second NG interface control plane message includes any one of the following 5.1 to 5.6:

[0686] 5.1. Initial terminal message

[0687] The access network device sends an initial terminal message to the core network device, and the initial terminal message includes the response information. After receiving the initial terminal message, the core network device can obtain the response information.

[0689] The access network device sends an uplink NAS transmission message to the core network device, and the uplink NAS transmission message includes the response information. After receiving the uplink NAS transmission message, the core network device can obtain the response information.

[0690] 5.3. Initial context establishment response message.

[0691] The initial context establishment response message may be used to respond to establishing the initial context. The initial context establishment response message may carry response information. The access network device sends the response information to the core network device via the initial context establishment response message.

[0692] 5.4. Terminal context modification response message.

[0693] The terminal context modification response message may be used to respond to modifying the terminal context. The terminal context modification response message may carry response information. The access network device sends the response information to the core network device via the terminal context modification response message.

[0694] 5.5. Terminal context release completion message.

[0695] The terminal context release complete message may be used to indicate completion of releasing the terminal context.

The access network device sends the response information to the core network device via the terminal context release complete message.

[0696] 5.6. Second new news.

[0697] The second new message is a type of NG interface control plane message, in addition to the existing Initial Terminal Message, Uplink NAS Transfer Message, Initial Context Establishment Response Message, Terminal Context Modification Response Message, and Terminal Context Release Complete Message. The second new message can carry response information, and the access network device sends the response information to the core network device via the second new message.

[0698] Optionally, the second new message includes at least one of a terminal inventory response message, a terminal positioning response message, a terminal read response message, and a terminal write response message, wherein the terminal inventory response message may be a response to the terminal inventory message, the terminal positioning response message may be a response to the terminal positioning message, the terminal read response message may be a response to the terminal read message, and the terminal write response message may be a response to the terminal write message.

[0699] The following describes the solutions of the embodiments of the present application with several specific examples.

[0700] In a first example, the core network device knows the terminal identifier of a terminal in advance. When a command needs to be written to the terminal or an inventory of the terminal needs to be taken, the core network device needs to find the terminal.

[0701] Example 1 is a DT service type. The core network device is triggered and requested to write certain information or obtain information about the terminal.

[0702] The core network device sends device indication information to the designated access network device.

[0703] The access network device receives the device indication information. If the device indication information is a control plane message, the access network device parses the message content; if the device indication information is service plane data, the access network device parses it to obtain data information.

[0704] In the case that the device indication information includes paging range information, the access network device determines a corresponding paging range based on the paging range information, and pages the corresponding terminal within the specified paging range.

[0705] Optionally, the access network device replies to the core network device with response information, and the response information may include the paging result, the operation result of the terminal command information, the operation result of the access network device command information, the terminal identifier of the found terminal, etc.

[0706] Example 2: Specify a group of terminals for paging.

[0707] The prerequisite for Example 2 is that the core network device has pre-assigned terminal identifiers or attribute group identifiers for a group of terminals. When writing commands for or counting terminals within this attribute group, the core network device must locate the terminals within this attribute group. The attribute group identifier indicates at least one of the following: terminal function attributes, terminal location attributes, terminal process attributes, or terminal usage attributes.

[0708] The core network device is triggered and requested to write certain information or obtain information about the terminals within the attribute group. The attribute group can be expressed in the form of an attribute group identifier, an attribute group type, etc., which is a system-preassigned attribute group identifier or attribute group type. If the device indication information sent by the core network device does not include an attribute group identifier, but includes the terminal identifiers of each terminal in the group, the access network device can page each terminal based on the terminal identifier of each terminal. The paging process is similar to Example 1.

[0709] The core network device sends device indication information to the designated access network device.

[0710] The access network device receives the device indication information. If the device indication information is a control plane message, the access network device parses the message content; if the device indication information is service plane data, the access network device parses it to obtain data information.

[0711] In the case that the device indication information includes terminal attribute information, the access network device determines a corresponding attribute group based on the terminal attribute information, and pages the corresponding terminal in the specified attribute group.

[0712] Optionally, the access network device replies with a response message to the core network device. The response message may include the paging result, the operation result of the terminal command message, the operation result of the access network device command message, the terminal identifier of the found terminal, etc. One response message may be replied to each terminal, or one response message may be replied to multiple terminals.

[0713] Example 3: Paging of an unspecified terminal.

[0714] The prerequisite for Example 3 is that the core network device broadcasts to all terminals to perform a certain type of service or a certain behavior. Example 3 belongs to the DT or DO-DTT service type.

[0715] The core network device is triggered to take inventory of the terminal identifications and corresponding information of all terminals within a specified area or within specified conditions.

[0716] The core network device sends device instruction information to the access network device in the corresponding area or the access network device that meets the specified conditions according to the specified area, as well as the corresponding terminal command information.

[0717] The access network device receives the device indication information. If the device indication information is a control plane message, the access network device parses the message content; if the device indication information is service plane data, the access network device parses it to obtain data information.

[0718] The access network device divides the air interface resources according to the resource grouping information and sends the resource grouping information to the terminal through a downlink message or signal. The terminal selects the appropriate resource to send an uplink signal or message, and the access network device receives it in the corresponding resource.

[0719] Optionally, the access network device replies with a response message to the core network device. The response message may include the paging result, the operation result of the terminal command message, the operation result of the access network device command message, the terminal identifier of the found terminal, etc. One response message may be replied to each terminal, or one response message may be replied to multiple terminals.

[0720] Example 4: Paging of an unspecified terminal.

[0721] The prerequisite for Example 4 is that the core network device broadcasts terminal identification information (for example, including terminal identification, range information of terminal identification, characteristic information of terminal identification, mask information of terminal identification, and bit identification information of terminal identification) to notify multiple terminals to perform a certain type of service or a certain behavior. Example 4 belongs to the DT or DO-DTT service type.

[0722] The core network device is triggered to count the terminal identification information of multiple terminals within a specified area or within specified conditions.

[0723] The core network device sends device instruction information to the access network device in the corresponding area or the access network device that meets the specified conditions according to the specified area, as well as the corresponding terminal command information.

[0724] The access network device receives the device indication information. If the device indication information is a control plane message, the access network device parses the message content; if the device indication information is service plane data, the access network device parses it to obtain data information.

[0725] The access network device divides the air interface resources according to the resource grouping information and sends the resource grouping information to the terminal through a downlink message or signal. The terminal selects the appropriate resource to send an uplink signal or message, and the access network device receives it in the corresponding resource.

[0726] Optionally, the access network device replies with a response message to the core network device. The response message may include the paging result, the operation result of the terminal command message, the operation result of the access network device command message, the terminal identifier of the found terminal, etc. One response message may be replied to each terminal, or one response message may be replied to multiple terminals.

[0727] Example 5: Paging via a relay device.

[0728] The core network device is triggered to page the specified terminal. It sends device indication information to the access network device in the corresponding area. This information includes paging range information, which includes a list of relay devices, indicating the corresponding relay devices. Based on the relay device list, the access network device forwards the device indication information to the corresponding relay device. If the context information of the terminal to be paged, recorded by the access network device, indicates that the terminal is connected to a relay device, the information is also forwarded to the corresponding relay device.

[0729] After receiving the operation result of the first operation of the terminal sent by the relay device, the access network device forwards the operation result information of the first operation to the core network device.

[0730] Example 6: The core network triggers an inventory of devices within a certain range - the access network device establishes a context process.

[0731] The core network device sends a paging message to the access network device, and the access network device triggers paging of all terminals within the statistical range.

[0732] The terminal reports the terminal identification information to the access network device, and the access network device sends an initial terminal message to the core network device. The initial terminal message carries the terminal identification A.

[0733] The core network device needs to operate on the reported terminal identifier A and send a context establishment request message to the access network device, and the access network device sends the context establishment request message to the terminal.

[0734] After executing the context establishment operation, the terminal replies to the access network device. The access network device sends a context establishment response message to the core network device.

[0735] If the core network device subsequently needs to operate on terminal identifier A, it can send a downlink NAS message, a context modification request message, or downlink service plane data to the access network device. After receiving the downlink NAS message, context modification request message, or downlink service plane data, the access network device sends it to the terminal.

[0736] After the terminal completes the corresponding operation, it replies to the access network device. The access network device accordingly sends an uplink NAS message, a context modification response message, or uplink service plane data to the core network device.

[0737] The core network device sends a Terminal Context Release Command message to the access network device. After the access network device performs the Terminal Context Release operation, it responds with a Terminal Context Release Complete message to the core network device. Both the Terminal Context Release Command and Terminal Context Release Complete messages carry the terminal's identification information, indicating that the access network device has completed the context release for the corresponding terminal.

[0738] The paging message and terminal context establishment request message mentioned above occur before the terminal context is established. At this time, the core network device may not have established the terminal context yet, so each message may not contain terminal context information.

[0739] Example 7: The core network triggers an inventory of devices within a certain range - the access network devices do not establish a context process.

[0740] The core network device sends a paging message to the access network device, and the access network device triggers paging of all terminals within the statistical range.

[0741] The terminal reports the terminal identification information to the access network device, and the access network device sends an initial terminal message or an uplink NAS transmission message to the core network device. The initial terminal message or the uplink NAS transmission message carries the terminal identification A.

[0742] The core network device needs to operate on the reported terminal identifier A and send a downlink NAS message or downlink service plane data to the access network device. The access network device sends the downlink NAS message or downlink service plane data to the terminal.

[0743] After the terminal performs the corresponding operation, it replies to the access network device. The access network device sends an uplink NAS message or uplink service plane data to the core network device.

[0744] The message or data sent by the core network device to the access network device may occur before the core network device establishes the terminal context, and therefore cannot contain the terminal context information.

[0745] In summary, the solution of the embodiment of the present application addresses the problem that passive terminals are unable to communicate with access network devices based on the current paging method. An interface implementation method is designed in combination with the application scenarios of the Internet of Things, which can effectively support the paging function of passive terminals and realize communication between terminals and access network devices through device indication information.
