[0054] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0055] The terms "first," "second," etc., used in this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, the first object can be one or more. Furthermore, "or" in this application indicates at least one of the connected objects. For example, the scope of protection for "A or B" covers at least three scenarios: Scenario 1: including A but not B; Scenario 2: including B but not A; Scenario 3: including both A and B. In addition, the terms "A and / or B," "at least one of A and B," and "at least one of A or B" also cover at least the above three scenarios. The character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0056] The term "instruction" in this application can be either a direct instruction (or explicit instruction) or an indirect instruction (or implicit instruction). A direct instruction can be understood as one in which the sender explicitly informs the receiver of specific information, the operation to be performed, or the requested result, etc., in the instruction sent. An indirect instruction can be understood as one in which the receiver determines the corresponding information based on the instruction sent by the sender, or makes a judgment and determines the operation to be performed or the requested result, etc., based on the judgment result.

[0057] It is worth noting that the technologies described in this application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be used in other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), or other systems. The terms "system" and "network" in this application are often used interchangeably, and the described technologies can be used in the systems and radio technologies mentioned above, as well as in other systems and radio technologies. The following description describes New Radio (NR) systems for illustrative purposes, and the term NR is used in most of the following description; however, these technologies can also be applied to systems other than NR systems, such as 6th Generation (6G) communication systems.

[0058] Figure 1 shows a block diagram of a wireless communication system applicable to an embodiment of this application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 can be a user equipment (UE) or other devices besides a UE. For example, the terminal 11 can be an AIoT device, mobile phone, tablet computer, laptop computer, notebook computer, personal digital assistant (PDA), handheld computer, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), augmented reality (AR), virtual reality (VR) device, robot, wearable device, flight vehicle, vehicle user equipment (VUE), shipboard equipment, pedestrian user equipment (PUE), smart home (home devices with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), game console, personal computer (PC), ATM, or self-service machine, etc. Wearable devices include: smartwatches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart chains, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among these, in-vehicle devices can also be referred to as in-vehicle terminals, in-vehicle controllers, in-vehicle modules, in-vehicle components, in-vehicle chips, or in-vehicle units, etc. It should be noted that the specific type of terminal 11 is not limited in this application embodiment. Network-side equipment 12 may include access network equipment or core network equipment, wherein access network equipment may also be referred to as Radio Access Network (RAN) equipment, radio access network function, or radio access network unit. Access network equipment may include base stations, Wireless Local Area Network (WLAN) access points (APs), or Wireless Fidelity (WiFi) nodes, etc.The term "base station" can be referred to as Node B (NB), Evolved Node B (eNB), Next Generation Node B (gNB), New Radio Node B (NR Node B), Access Point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), Radio Base Station, Radio Transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B, Transmit / Receive Point (TRP), or any other suitable term in the relevant field, as long as the same technical effect is achieved. The term "base station" is not limited to any specific technical terminology. It should be noted that this application embodiment only uses a base station in an NR system as an example for description and does not limit the specific type of base station.

[0059] Core network equipment, also known as core network nodes, core network functions, or core network elements, includes, but is not limited to, at least one of the following: Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (or L-NEF), and Binding Support. The core network functions include: BSF (Block Network Function), Application Function (AF), Location Management Function (LMF), Gateway Mobile Location Centre (GMLC), and Network Data Analytics Function (NWDAF). It should be noted that this application embodiment only uses core network equipment in the NR system as an example and does not limit the specific type of core network equipment. If the name of the core network equipment mentioned in this application embodiment changes in subsequent protocol versions (e.g., 6G), it will still be within the scope of protection of this application.

[0060] Optionally, the core network equipment can be implemented by one or more functional modules in a single device, or by multiple devices working together; this application does not specifically limit this. It is understood that the aforementioned functional modules can be network elements in hardware devices, software functional modules running on dedicated hardware, or virtualized functional modules instantiated on a platform (e.g., a cloud platform).

[0061] Typically, AIoT devices are characterized by ultra-low complexity and ultra-low power consumption. During data transmission between the AIoT device and the AIoT application, terminal 11 can act as a reader to transmit data from the AIoT device to the AIoT application. It is understood that because the overall power consumption of the AIoT device terminal is low, its communication energy can come from the environment, such as wind power, kinetic energy, heat energy, radio frequency (RF) signals, etc. Optionally, the AIoT device terminal can also be described as a passive IoT device or a responding device.

[0062] It should be noted that AIoT is a type of Internet of Things (IoT) service. During the AIoT Radio Resource Control (RRC) process, NG-RAN can perform NG settings on AIoTF.

[0063] The AIoTF can generate Non-Access Stratum (NAS) messages and send them to the NG-RAN as non-terminal-related signaling. The NG-RAN can act as an intermediary terminal for AIoT operations, including selecting intermediary terminals (e.g., based on the AIoTF's candidate terminal list), sending operation commands to the intermediary terminals, and forwarding the results from the intermediary terminals to the AIoTF. It is understood that since licensed spectrum is typically owned by operators, the NG-RAN can provide the intermediary terminals with the spectrum information of the air interface between the intermediary terminals and the AIoT devices for data transmission.

[0064] Figure 2 shows a schematic diagram of the system architecture for using AIoTF to coordinate the RAN-Core Network (CN) in Topology 2. AIoTF can distribute NAS messages from AIoT devices to the NG-RAN; the NG-RAN can identify intermediate terminals, allocate radio resources for communication between the intermediate terminals and AIoT devices, forward the device NAS messages to the intermediate UEs, and forward the responses to AIoTF.

[0065] Figure 3 shows a schematic diagram of the protocol stack used for topology 2 to coordinate the RAN-CN using AIoTF. The AIoT device NAS layer can include the NAS protocol between AIoTF and AIoT devices; the AIoT Authentication Server (AS) layer can include the AS protocol layer between the terminal acting as a reader and the AIoT device, including the physical layer and the Media Access Control (MAC) layer. The application layer (App layer) can include the application layer protocol between the AIoT device and the application function (AF).

[0066] It should be noted that in NG-RAN, the AIoT service operation information received in NGAP can be mirrored to the Uu AS layer.

[0067] Typically, AIoTF can send an AIoT operation request carrying a specific target area to NG-RAN. NG-RAN can then select and determine the required terminal in that target area, and send messages such as inventory requests and command requests to AIoTF through that terminal to complete the communication between NG-RAN and AIoTF.

[0068] However, for some third-party applications, the corresponding application services need to be completed through a designated terminal. Since the AIoTF and NG-RAN use non-terminal-associated signaling, meaning the messages between AIoTF and NG-RAN are unrelated to the terminal, even if the non-terminal-associated signaling carries a terminal identifier, NG-RAN cannot recognize this identifier, thus preventing the execution of the corresponding AIoT operation through the designated intermediate terminal.

[0069] Figure 4 shows the inventory process of the application in RRC under AIoT, which may include the following steps S101 to S115.

[0070] Step S101: AF sends an inventory request to AIoTF.

[0071] Step S102: AIoTF generates a candidate terminal list.

[0072] Step S103: NG-RAN paging terminal in the expected area.

[0073] It is understandable that this terminal can serve as an intermediate terminal for the reader / writer.

[0074] Step S104: AIoTF sends an inventory request to NG-RAN.

[0075] The aforementioned inventory request may include expected area information, AIoT device information, inventory strategy, and terminal location information.

[0076] Step S105: NG-RAN determines the terminal.

[0077] Step S106: NG-RAN sends an inventory request to the terminal.

[0078] The inventory request may include radio resource information, AIoT device information, inventory strategy, location information (tracking area or cell), etc.

[0079] Step S107: Start the terminal inventory process.

[0080] Step S108: The AIoT device sends its device ID and optional device functions to the terminal.

[0081] Step S109: The terminal sends an inventory response to the AIoTF via NG-RAN.

[0082] Understandably, the above-mentioned inventory response can also be referred to as an inventory notification.

[0083] The inventory response may include the device ID of the AIoT device, optional device functions, terminal location information, and an end indicator.

[0084] Step S110: AIoTF verifies the device ID and checks device performance.

[0085] Step S111: AIoT device authentication and authorization.

[0086] Step S112: If the AIoT device is able to store the received parameters for a long time, perform security negotiation with the AIoT device.

[0087] Step S113: AIoTF assigns a CN device ID and sends it to the AIoT device.

[0088] Step S114: AIoTF registers with Unified Data Management (UDM).

[0089] Step S115: AIoTF summarizes the inventory report and sends it to AF.

[0090] Figure 5 shows the command process under AIoT, which may include the following steps S201 to S222.

[0091] Step S201: AF sends a command request to the Network Exposure Function (NEF).

[0092] The aforementioned command request may include commands, area information, device information, required location, report aggregation information, etc.

[0093] Step S202: Request and translate region information using the NEF authorization command.

[0094] Step S203a: NEF queries the Network Repository Function (NRF).

[0095] NRF can be used to query the aforementioned region information.

[0096] Step S203b: NEF obtains the service NF from UDM.

[0097] NEF can obtain the device ID from UDM.

[0098] Step S204: NEF sends a command request to AIoTF.

[0099] The aforementioned command request may include commands, area information, device information, required location, report aggregation information, etc.

[0100] Step S205: AIoTF obtains registered AIoT devices.

[0101] Step S206: NG-RAN is a paging terminal for registered AIoT devices.

[0102] It is understandable that this terminal can serve as an intermediate terminal for the reader / writer.

[0103] Step S207: AIoTF sends a command request to NG-RAN.

[0104] The aforementioned command request may include radio resource information, commands, registered AIoT devices, service IDs, etc.

[0105] Step S208: NG-RAN sends a command request to the terminal.

[0106] The aforementioned command request may include radio resource information, commands, registered AIoT devices, service IDs, etc.

[0108] Step S210: The AIoT device sends the command result to the terminal.

[0109] Step S211: The terminal sends a command response to the AIoTF via NG-RAN.

[0110] Understandably, the aforementioned inventory response can also be referred to as an inventory notification. This inventory notification may carry the command result.

[0111] Step S212: AIoTF performs aggregation on the command results.

[0112] Step S213: AIoTF sends the command result to NEF.

[0113] The command results mentioned above can also be referred to as command responses to aggregated command results or command notifications to aggregated command results.

[0114] Step S214: NEF sends the command result to AF.

[0115] Step S215: Perform an inventory process for unregistered AIoT devices with transaction IDs.

[0117] The command request may include command operations, which include at least one of the following: read operation; write operation; activation operation; deactivation operation; notification operation; operation to locate the AIoT device; and operation to broadcast the AIoT device ID.

[0118] Step S217: NG-RAN sends a command request to the terminal.

[0120] Step S218: The terminal transmits commands to the AIoT device.

[0121] Step S219: The AIoT device sends the command result to the terminal.

[0122] Step S220: The terminal sends a command response to the AIoTF via NG-RAN.

[0123] It is understandable that this command response can also be referred to as a command notification. The command response may include the device ID and the command result.

[0124] Step S221: AIoTF sends the command result to NEF.

[0125] The command results mentioned above can also be referred to as command responses to aggregated command results or command notifications to aggregated command results.

[0126] Step S222: NEF sends the command result to AF.

[0127] It should be noted that the steps shown by the dashed lines in Figures 4 and 5 above can be considered optional steps.

[0128] However, for a specific terminal, such as the terminal that the AF specifies as the reader / writer in the inventory request in step S101, there is no indication in the relevant technology of how the AIoTF enables the NG-RAN to select the specified terminal in step S104.

[0129] Furthermore, since AIoTF does not know the information of the terminal served by NG-RAN, it will be unable to find the RAN serving the specified terminal.

[0130] In practice, AIoTF may initially screen some terminals acting as readers, but not all of these terminals will perform AIoT operations. In other words, AIoTF can provide this information about the terminals acting as readers to NG-RAN, and NG-RAN will determine which terminals will ultimately perform AIoT operations and allocate resources to them as readers.

[0131] Furthermore, core network devices such as AIoTF can specify a candidate list of readers for access network devices to select from, or specify a list of readers and request access network devices to allocate resources to the readers in that list. How access network devices distinguish between these two types of list operations is unclear. Therefore, how to differentiate between these two requirements needs to be addressed.

[0132] However, even when the AF specifies a terminal, NG-RAN cannot distinguish between the terminal provided by AIoTF and the terminal specified by AF. Therefore, in this case, even if the AF specifies a terminal, that terminal may not be selected by NG-RAN to perform AIoT operations. Thus, how to make NG-RAN select the terminal specified by AF in this situation is an urgent problem to be solved.

[0133] The communication method, apparatus, network-side device, medium, and computer program product provided in this application can obtain different identifiers of terminals and thus obtain the relationship between these different identifiers. In the case of a specified terminal, the access network device can accurately identify the specified terminal acting as a reader / writer, and thus perform a corresponding operation through the terminal.

[0134] The communication methods, apparatus, network-side devices, media, and computer program products provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0176] It is understood that a reader / writer device can refer to a device that supports reader / writer functionality (such as a terminal, base station, etc.). That is, a reader / writer device may only support reader / writer functionality, or it may support more than just reader / writer functionality.

[0190] In some embodiments of this application, the command executed by the control terminal may also be referred to as a control operation, such as sending a command to the terminal, or controlling the actuator or terminal associated with the terminal to execute the command.

[0191] In some embodiments of this application, the above-described operation of transmitting information to the terminal may be transparent to at least one of the reader / writer and the CN device (such as an AIoT function).

[0192] In some embodiments of this application, the first terminal described above can serve as an intermediate device to perform communication between the first network-side device and the second network-side device.

[0193] It is understood that the aforementioned first network-side device can communicate directly with the second network-side device, or communicate with the second network-side device through an intermediate device. It is also understood that when the first network-side device is far from the terminal device, the first network-side device can extend the reader's coverage area through the intermediate device. In this case, the intermediate device is also referred to as a reader or a component of the reader.

[0194] In some embodiments of this application, the intermediate device may be an intermediate node located between the first network-side device and other network devices (such as access network devices or readers). This intermediate device may extend the coverage of the other network devices, or facilitate communication between the first network-side device and other network devices, but is not limited thereto.

[0195] In some embodiments of this application, the aforementioned intermediate device may include, but is not limited to, a terminal, an integrated access and backhaul (IAB), a relay, etc.

[0196] In some embodiments of this application, after step 101 described above, the communication method provided in the embodiments of this application may further include step 102 as described below.

[0197] Step 102: The first network-side device performs the first operation based on the first information.

[0198] The "perform first operation" in step 102 above may include at least one of the following: establishing or saving a first relationship; saving first information; determining a first identifier based on the first relationship; determining a second network-side device corresponding to the first terminal based on the second information; and sending the first identifier to the second network-side device.

[0199] In some embodiments of this application, the first relationship described above may include a first identifier and a second identifier.

[0200] In some embodiments of this application, the above-mentioned saving of the first relationship and / or saving of the first information may be done in the context of the terminal.

[0201] In some embodiments of this application, the first network-side device determines the first identifier based on the first relationship through the following methods.

[0202] Steps A and B are completed.

[0203] Step A: The first network-side device obtains the second identifier.

[0204] Step B: The first network-side device determines the first identifier based on the first relationship and the second identifier.

[0205] In some embodiments of this application, the first relationship described above can be a mapping relationship between a first identifier and a second identifier.

[0206] In some embodiments of this application, the aforementioned second identifier can be the identifier of the first terminal in the first network-side device. That is, the first network-side device can obtain the second device of the first terminal stored in the first network-side device.

[0207] In some embodiments of this application, after obtaining the second identifier, the first network-side device can determine the first identifier corresponding to the second identifier based on the mapping relationship between the first identifier and the second identifier.

[0208] In this way, the first network-side device can accurately identify the specified terminal by the terminal's identifier and the relationship between the identifiers.

[0209] In some embodiments of this application, the establishment or saving of the first relationship by the first network-side device may include at least one of the following steps C and D:

[0210] Step C: The first network-side device establishes or saves the first relationship based on the first identifier and the second identifier in the first network-side device.

[0211] Step D: The first network-side device establishes or saves the first relationship based on the first identifier and the second identifier.

[0212] It is understandable that after establishing or saving the first relationship, the first network-side device can identify the terminal through the first relationship.

[0213] In some embodiments of this application, the first network-side device determining the second network-side device corresponding to the terminal based on the second information may include at least one of the following steps E to H:

[0214] Step E: The first network-side device determines the second network-side device corresponding to the first terminal based on the ID of the second network-side device in the second information.

[0215] It is understandable that the second network-side device corresponding to the first terminal mentioned above is the second network-side device identified by this ID.

[0216] Step F: The first network-side device determines the second network-side device corresponding to the first terminal based on the global RAN node ID in the second information.

[0217] It is understandable that the second network-side device corresponding to the first terminal mentioned above is the second network-side device identified by the global RAN node ID.

[0218] Step G: The first network-side device determines the second network-side device corresponding to the terminal based on the IP address of the second network-side device in the second information.

[0219] It is understandable that the second network-side device corresponding to the first terminal mentioned above is the same as the second network-side device corresponding to the IP address.

[0220] Step H: The first network-side device determines the second network-side device corresponding to the terminal based on the terminal's location information in the second information.

[0221] For example, the location information of the terminal can be the terminal's TA or cell information, and the first network-side device can select the second network-side device according to the network-side device corresponding to the serving TA or cell.

[0222] Thus, after determining the second network-side device corresponding to the first terminal, the first network-side device can send the identifier of the specified terminal to the second network-side device, so that the second network-side device can identify the execution terminal and perform the corresponding operation based on the specified terminal.

[0223] In some embodiments of this application, the sending of the first identifier by the first network-side device to the second network-side device can be specifically achieved by at least one of the following steps I and J.

[0224] Step 1: The first network-side device sends a first operation request to the second network-side device.

[0225] The first operation request may carry a first identifier, which can be used to request the execution of the second operation.

[0226] Step J: The first network-side device sends a second operation request and a first identifier to the second network-side device.

[0227] The aforementioned second operation request can be used to request the execution of a second operation.

[0228] In some embodiments of this application, the second operation described above includes at least one of the following: inventory operation; command operation; read operation; write operation; activation operation; deactivation operation; notification operation; operation to locate AIoT devices; identification MASK; device ID report; read command; read response; write command; write response; disable request; disable response; security command / response.

[0229] In some embodiments of this application, the aforementioned MASK identifier can be a special occlusion identifier MASK.

[0230] In some embodiments of this application, the above command operations include at least one of the following: read operation; write operation; activation operation; deactivation operation; notification operation; operation to locate the AIoT device; operation to broadcast the AIoT device ID; and security operation.

[0231] In some embodiments of this application, the above-described security operations can be used for encryption or integrity protection of signaling or data between the AIoT device and the first network-side device, or the above-described security operations can be used for encryption or integrity protection of signaling or data between the first terminal and the first network-side device.

[0232] In some embodiments of this application, step 101 described above can be implemented by step 101a as follows.

[0233] Step 101a: The first network-side device receives first information from the third network-side device.

[0234] In some embodiments of this application, the aforementioned third network-side device may be an AMF.

[0235] It is understandable that the third network-side device can store the first information, so that the third network-side device can send the first information to the first network-side device, so that the first network-side device can perform a response operation based on the first information after obtaining the first information.

[0236] In some embodiments of this application, before step 101a above, the communication method provided in the embodiments of this application may further include step 101b below.

[0237] Step 101b: The first network-side device sends a first request to the third network-side device.

[0238] The aforementioned first request can be used to request first information.

[0239] In some embodiments of this application, the first request described above may carry a second identifier of the first terminal.

[0240] Thus, after receiving the first request from the first network side device, the third network side device can send the first information to the first network side device, so that the first network side device can perform a response operation based on the first information after obtaining it.

[0241] Figure 7 shows a flowchart of a communication method provided in an embodiment of this application. As shown in Figure 7, the communication method may include the following step 201.

[0242] Step 201: The third network-side device sends the first information to the first network-side device.

[0243] The first information may include at least one of the following: a first identifier of the first terminal, or a first identifier of the first terminal and a second identifier of the first terminal; second information.

[0244] In this embodiment of the application, the aforementioned second information can be used to determine the second network-side device corresponding to the first terminal.

[0245] In this embodiment of the application, the first identifier is the identifier of the first terminal in the second network-side device.

[0246] In this embodiment of the application, the second identifier must satisfy at least one of the following: the second identifier is different from the first identifier;

[0247] The second identifier is not the terminal identifier of the access layer; the second identifier is the identifier of the first terminal in the first network-side device.

[0248] In some embodiments of this application, the first identifier of the terminal may include at least one of the following: RAN UE NGAP ID; AMF UE NGAP ID; 5G-S-TMSI; C-RNTI.

[0249] In some embodiments of this application, the second network-side device corresponding to the first terminal mentioned above includes one of the following: an access network device for terminal access, an access network device for serving the terminal, and an access network device for storing terminal context.

[0250] In some embodiments of this application, the second identifier mentioned above includes at least one of the following: SUPI, GUTI, 5G-GUTI, 5G-S-TMSI, GPSI, and the identifier of the reader / writer.

[0251] In some embodiments of this application, the second information mentioned above includes at least one of the following: the ID of the second network-side device; the address information of the second network-side device; and the location information of the first terminal.

[0252] In some embodiments of this application, before step 201 above, the communication method provided in the embodiments of this application may further include step 202 below.

[0253] Step 202: The third network-side device receives the first request from the first network-side device.

[0254] The aforementioned first request can be used to request first information.

[0255] It should be noted that the descriptions of steps 201 and 202 above can be found in the detailed descriptions of steps 101, 101a, 102, and steps A to J above. To avoid repetition, they will not be repeated here.

[0256] The communication method provided in this application embodiment can obtain the relationship between different identifiers of the terminal by obtaining different identifiers of the terminal. In the case of a specified terminal, the access network device can accurately identify the specified terminal as a reader / writer, and thus perform AIoT operations through the terminal.

[0257] The following specific examples illustrate the communication method provided in the embodiments of this application.

[0258] Example 1: Taking AIoTF as the first network-side device, NG-RAN as the second network-side device, and AMF as the third network-side device as an example, for a specified terminal, AIoTF obtains the terminal's ID in NG-RAN and the ID of the NG-RAN serving the terminal from AMF.

[0259] As shown in Figure 8, the communication method may include the following steps S301 to S306.

[0260] Step S301: AF sends an AIoT operation service request to AIoTF.

[0261] The AIoT operation service request carries the identifier of the terminal specified by AF.

[0262] For example, the AIoT operation service request can be an inventory request or a command request, which carries the IDs (list) of terminals designated by AF as readers.

[0263] For example, the ID of the terminal designated by the AF as the reader can be the terminal's GPSI.

[0264] It is understandable that the IDs (list) of terminals specified by AF as readers can be used to indicate the use of a terminal as a reader to perform AIoT service operations.

[0265] Step S302: AIoTF requests AMF to make the terminal acting as a reader reachable, thereby triggering paging so that the terminal acting as a reader enters the connected state.

[0266] Step S303: AIoTF sends the first request to AMF.

[0267] The first request is used to obtain first information, which may include at least one of the following: a first identifier of the terminal, and second information.

[0268] The first identifier mentioned above can be information used to identify the terminal in NG-RAN.

[0269] The NG-RAN includes one of the following: the NG-RAN accessed by the terminal, or the NG-RAN serving the terminal, or the NG-RAN storing the terminal context.

[0270] It is understood that the information used to identify a terminal in NG-RAN includes the terminal's first identifier, which includes at least one of the following: the terminal's identifier in NG-RAN, the terminal identifier on the access network side of the first interface (interface between the access device and the CN device (such as CN), RAN UE NGAP ID, AMF UE NGAP ID, 5G-S-TMSI, C-RNTI, etc.

[0271] The second piece of information mentioned above can be used to determine the NG-RAN of the terminal.

[0272] For example, the second piece of information may include the NG-RAN ID or IP address.

[0273] Step S304: AIoTF receives the response to the first request sent by AMF.

[0274] The response to the first request may include the aforementioned first information.

[0275] It should be noted that, for steps S303 and S304, AIoTF can obtain the terminal's ID on the RAN side (within) and / or the NG-RAN information serving the terminal from AMF.

[0276] In some embodiments of this application, the AMF can also directly send the terminal's ID on the RAN side (within) and / or the NG-RAN information serving the terminal to the AIoTF when establishing the terminal context. That is, the AIoTF can obtain the aforementioned first information without explicitly requesting it from the AMF.

[0277] Step S305: AIoTF sends an AIoT operation service request to NG-RAN.

[0278] AIoTF can determine the first identifier based on the first information.

[0279] In some embodiments of this application, the aforementioned AIoT operation service request may include, but is not limited to, inventory operation requests, command requests, etc. It is understood that the AIoT operation service request may carry a first identifier, which can be used to instruct the NG-RAN to use the terminal corresponding to the first identifier to perform the AIoT operation service.

[0280] It should be noted that the information or signaling carried when sending an AIoT operation service request to NG-RAN can be non-terminal related.

[0281] In some embodiments of this application, when the response to the first request includes second information, the AIoTF can send an AIoT operation service request to the NG-RAN indicated by the second information, including the RAN information carried in the header of the AIoT operation service request message to identify that the AIoT operation service request is sent to the NG-RAN.

[0282] It is understandable that, for a specific terminal reader, such as when the AF specifies the terminal reader in the AIoT operation request (e.g., inventory request, command request), the AIoTF can find the corresponding NG-RAN based on the second information, which can solve the problem of how the AIOTF finds the NG-RAN served by the terminal reader.

[0283] Step S306: NG-RAN sends an AIoT operation service request to the terminal indicated by the first identifier.

[0284] In this way, by obtaining the different identifiers of the terminal, the relationship between the different identifiers can be obtained, so that when a specific terminal is specified, the access network device can accurately identify the specified terminal as a reader / writer, and thus perform the corresponding operation through the terminal.

[0285] Figure 9 shows a flowchart of a communication method provided in an embodiment of this application. As shown in Figure 9, the communication method may include the following step 301.

[0286] Step 301: The second network-side device obtains the third information.

[0287] The aforementioned third information may include the second identifier of the first terminal, or the first identifier of the first terminal and the second identifier of the first terminal.

[0288] In this embodiment of the application, the first identifier can be the identifier of the first terminal in the second network-side device.

[0289] In this embodiment of the application, the second identifier must satisfy at least one of the following: the second identifier is different from the first identifier; the second identifier is not a terminal identifier of the access layer; the second identifier is the identifier of the first terminal in the first network-side device.

[0290] In some embodiments of this application, when the third information includes the first identifier and the second identifier of the first terminal, the third information may include a second relationship, which may include the relationship between the first identifier and the second identifier of the first terminal.

[0291] In some embodiments of this application, the first identifier mentioned above includes at least one of the following: RAN UE NGAP ID; AMF UE NGAP ID; 5G-S-TMSI; C-RNTI.

[0292] In some embodiments of this application, the second network-side device mentioned above includes one of the following: an access network device for the first terminal to access, an access network device for serving the first terminal, and an access network device for storing the context of the first terminal.

[0293] In some embodiments of this application, the second identifier mentioned above includes at least one of the following: SUPI, GUTI, 5G-GUTI, 5G-S-TMSI, GPSI, and the identifier of the reader / writer.

[0294] In some embodiments of this application, after step 301 above, the communication method provided by the embodiments of this application may further include step 302 as described below.

[0295] Step 302: The second network-side device performs a third operation based on the third information.

[0296] The "perform a third operation" in step 302 above may include at least one of the following: establishing or saving a second relationship; saving third information; determining a first identifier or a first terminal based on the second relationship.

[0322] The communication method provided in this application embodiment can obtain different identifiers of the terminal and thus obtain the relationship between the different identifiers. In the case of a specified terminal, the access network device can accurately identify the specified terminal as a reader / writer, and thus perform the corresponding operation through the terminal.

[0324] Step 401: The third network-side device sends third information to the second network-side device.

[0325] The aforementioned third information may include the second identifier of the first terminal, or the first identifier of the first terminal and the second identifier of the first terminal.

[0326] In this embodiment of the application, the first identifier can be the identifier of the first terminal in the second network-side device.

[0328] In some embodiments of this application, the first identifier may include at least one of the following: RAN UE NGAP ID; AMF UE NGAP ID; 5G-S-TMSI; C-RNTI.

[0329] In some embodiments of this application, the second network-side device mentioned above includes one of the following: an access network device for the first terminal to access, an access network device for serving the first terminal, and an access network device for storing the context of the first terminal.

[0332] Step 402: The third network-side device receives a second request from the second network-side device. The second request is used to request third information.

[0333] It should be noted that the descriptions of steps 401 and 402 above can be found in the detailed descriptions of steps 101, 101a, 102, and steps A to J above. To avoid repetition, they will not be repeated here.

[0334] The communication method provided in this application embodiment can obtain different identifiers of the terminal and thus obtain the relationship between the different identifiers. In the case of a specified terminal, the access network device can accurately identify the specified terminal as a reader / writer, and thus perform the corresponding operation through the terminal.

[0335] Figure 11 shows a flowchart of a communication method provided in an embodiment of this application. As shown in Figure 11, the communication method may include the following step 501.

[0336] Step 501: The first network-side device sends the second identifier of the first terminal to the second network-side device.

[0337] In some embodiments of this application, step 501 can be implemented by at least one of steps 501a and 501b described below.

[0338] Step 501a: The first network-side device sends a third operation request to the second network-side device.

[0339] The third operation request may carry a second identifier, and the first operation request is used to request the execution of the fourth operation.

[0340] Step 501b: The first network-side device sends a fourth operation request and a second identifier to the second network-side device.

[0341] The aforementioned fourth operation request is used to request the execution of a fourth operation.

[0342] It should be noted that the relevant description of step 501 above can be found in the detailed description of steps 101, 101a, 102, and steps A to J above. To avoid repetition, it will not be repeated here.

[0343] The communication method provided in this application embodiment can obtain different identifiers of the terminal and thus obtain the relationship between the different identifiers. In the case of a specified terminal, the access network device can accurately identify the specified terminal as a reader / writer, and thus perform the corresponding operation through the terminal.

[0344] The following specific examples illustrate the communication method provided in the embodiments of this application.

[0345] Example 2: Taking AIoTF as the first network-side device, NG-RAN as the second network-side device, and AMF as the third network-side device as an example, NG-RAN can obtain the relationship between the terminal's ID in NG-RAN and the terminal's ID in the core network such as AIoTF or a third party from AMF, and determine the terminal based on the relationship, thereby sending AIoT operation to the terminal.

[0346] As shown in Figure 12, the communication method may include the following steps S401 to S406.

[0347] Step S401: AMF sends third information to NG-RAN.

[0348] Step S402: AIoTF receives the AIoT operation service request sent by AF.

[0349] The AIoT operation service request may include, but is not limited to, inventory requests, command requests, etc.

[0350] In some embodiments of this application, the above-mentioned AIoT operation service request may carry the ID (list) of a specified terminal, such as the terminal's GPSI, and the ID (list) of the specified terminal carried is used to indicate the use of the terminal to perform AIoT service operations.

[0351] Step S403: AIoTF sends the first request to AMF.

[0352] Step S404: AIoTF receives the response to the first request sent by AMF.

[0353] It is understood that steps S303 and S304 above are optional steps.

[0354] Step S405: AIoTF sends an AIoT operation service request to NG-RAN.

[0355] The AIoT operation service request may include a second identifier for the terminal.

[0356] Step S406: NG-RAN determines the first identifier and sends an AIoT operation service request to the terminal corresponding to the first identifier.

[0357] In this way, by obtaining the different identifiers of the terminal, the relationship between the different identifiers can be obtained, so that when a specific terminal is specified, the access network device can accurately identify the specified terminal as a reader / writer, and thus perform the corresponding operation through the terminal.

[0358] The following example uses AIoTF as the first network-side device, NG-RAN as the second network-side device, and AMF as the third network-side device. AMF can send different identifiers of the terminal to NG-RAN and AIoTF respectively.

[0359] As shown in Figure 13, the communication method may include the following steps S501 to S506.

[0360] Step S501: AMF sends third information to NG-RAN.

[0361] Step S502: AIoTF receives the AIoT operation service request sent by AF.

[0362] Step S503: AIoTF sends the first request to AMF.

[0363] The first request carries a second identifier.

[0364] Step S504: AMF sends a response to the first request to AIoTF.

[0365] The response to the first request may carry first information.

[0366] Step S505: AIoTF sends an AIoT operation service request to NG-RAN.

[0367] Step S506: NG-RAN determines the first identifier and sends an AIoT operation service request to the terminal corresponding to the first identifier.

[0368] In this way, by obtaining the different identifiers of the terminal, the relationship between the different identifiers can be obtained, so that when a specific terminal is specified, the access network device can accurately identify the specified terminal as a reader / writer, and thus perform the corresponding operation through the terminal.

[0369] Figure 14 shows a flowchart of a communication method provided in an embodiment of this application. As shown in Figure 14, the communication method may include the following steps 601 and 602.

[0370] Step 601: The second network-side device obtains the fourth information.

[0371] The aforementioned fourth information may include at least one of the following: information for indicating the first terminal list, information for indicating the second terminal list, information for indicating the third terminal list, and first indication information.

[0372] Step 602: The second network-side device performs the fifth operation based on the fourth information.

[0373] The fifth operation mentioned above may include at least one of the following: selecting the terminal as a reader / writer, and allocating resources to the terminal as a reader / writer.

[0374] In some embodiments of this application, the first terminal list may satisfy at least one of the following: the first terminal list is a candidate reader / writer list; the first terminal list is used to select one or more terminals as readers / writers; the first terminal list includes information about one or more terminals, which are candidate terminals for readers / writers.

[0375] In some embodiments of this application, the aforementioned first terminal list is a candidate reader / writer list, or the first terminal list is used to select one or more terminals as readers / writers, or the first terminal list includes information on one or more candidate terminals as readers / writers, which can indicate that the first terminal list represents the selection range of readers / writers. That is, the second network-side device can select one or more terminals as readers / writers from the first terminal list.

[0376] In some embodiments of this application, the first terminal list is a candidate reader list, which can be understood as the selection range or candidate range of readers.

[0377] In some embodiments of this application, the second terminal list described above may satisfy at least one of the following: the second terminal list is used to indicate the allocation of resources as readers / writers for terminals in the second terminal list; the second terminal list includes information on one or more terminals, which are readers / writers.

[0378] In some embodiments of this application, the aforementioned third terminal list may include at least one terminal.

[0379] In some embodiments of this application, the first indication information described above can be used to indicate at least one of the following: the third terminal list is a first terminal list or a second terminal list; the third terminal list is a candidate reader / writer list; one or more terminals are selected as readers / writers in the third terminal list; the third terminal list includes information about one or more terminals, which are candidate terminals for readers / writers; the third terminal list is used to request the allocation of resources for the terminals in the third terminal list to be readers / writers; the third terminal list includes information about one or more terminals, which are readers / writers.

[0380] In some embodiments of this application, the aforementioned third terminal list is a candidate reader list, which can be understood as the selection range or candidate range of readers.

[0381] In some embodiments of this application, the aforementioned third terminal list is a selection range or candidate range of readers, which means that the second network-side device can select one or more terminals as readers from the third terminal list.

[0382] In some embodiments of this application, selecting one or more terminals as readers / writers can also mean activating a terminal as a reader / writer, or allocating resources to a terminal as a reader / writer. These three terms have the same meaning and can be used interchangeably.

[0383] In some embodiments of this application, selecting a terminal as a reader / writer to perform AIoT operations may also mean at least one of the following: activating the terminal as a reader / writer to perform AIoT operations, or allocating resources to the terminal as a reader / writer to perform AIoT operations.

[0384] In some embodiments of this application, one implementation of selecting one or more terminals as readers from the third terminal list may be as follows: not all terminals in the third terminal list are selected as readers. For example, the second network-side device may further consider the location of the terminal and the wireless signal strength before making a selection.

[0385] It should be noted that all terminals in the aforementioned third terminal list may also be selected as readers / writers. This application does not impose specific limitations on the embodiments described.

[0386] In some embodiments of this application, the above-mentioned allocation of resources as readers for terminals in the third terminal list can refer to allocating resources as readers for all terminals in the third terminal list.

[0387] Understandably, in this scenario, all terminals in the third terminal list have already been designated as readers. Therefore, the second network-side device only needs to allocate resources to all terminals in the third terminal list, without needing to further select terminals as readers.

[0388] It should be noted that if resources are insufficient, it is also possible that some terminals in the third terminal list will not be allocated resources, which is an abnormal situation.

[0389] In some embodiments of this application, the information described above for indicating the first terminal list includes at least one terminal identifier.

[0390] In some embodiments of this application, when the first terminal list includes one or more terminals, the information used to indicate the first terminal list may include the respective terminal identifiers of the one or more terminals.

[0391] In some embodiments of this application, the information described above for indicating the first terminal list may also be a list of terminal identifiers.

[0392] In some embodiments of this application, the fourth information may include information for indicating the first terminal list, and the fifth operation includes: selecting a terminal as a reader / writer.

[0393] In some embodiments of this application, the second network-side device selects the terminal as the reader / writer through the following step Q.

[0394] Step Q: The second network-side device selects a terminal as a reader / writer based on the first terminal list.

[0395] The aforementioned terminals can be terminals from the first terminal list.

[0396] It is understandable that the aforementioned second network-side device can also allocate resources as readers / writers to selected terminals.

[0397] In some embodiments of this application, where the fourth information includes information for indicating a second terminal list, step 602 may include step 602a as described below.

[0398] Step 602a: The second network-side device allocates resources as readers / writers to the terminals according to the second terminal list.

[0399] The aforementioned terminals can be terminals from the second terminal list.

[0400] In some embodiments of this application, where the fourth information includes information for indicating a third terminal list and first indication information, step 602 may include step 602b as described below.

[0401] Step 602b: The second network-side device selects a terminal based on the third terminal list and the first instruction information.

[0402] Wherein, the terminal is a terminal in the third terminal list, and the first indication information is used to indicate at least one of the following: the third terminal list is the selection range of terminals as readers; one or more terminals are selected from the third terminal list as readers.

[0403] In some embodiments of this application, when the fourth information includes information for indicating a third terminal list and first indication information, step 602 may include step 602c as described below.

[0404] Step 602c: The second network-side device allocates resources as readers / writers to the terminals based on the third terminal list and the first instruction information.

[0405] The aforementioned terminals can be terminals in the third terminal list. The first instruction information includes information for instructing at least one of the following: selecting all terminals in the third terminal list as readers / writers; allocating resources for the terminals in the third terminal list to serve as readers / writers.

[0406] In some embodiments of this application, the reader / writer described above can be a reader / writer that performs environmental Internet of Things (AIoT) operations.

[0407] In some embodiments of this application, the above-mentioned AIoT operations include at least one of the following: inventory operation; command operation; read operation; write operation; activation operation; deactivation operation; notification operation; operation to locate AIoT devices; identification MASK; device ID report; read command; read response; write command; write response; disable request; disable response; security command / response.

[0409] In some embodiments of this application, the above-described security operations can be used for encryption or integrity protection of signaling or data between the AIoT device and the first network-side device, or the above-described security operations can be used for encryption or integrity protection of signaling or data between the terminal and the first network-side device.

[0410] The communication method provided in this application allows the second network-side device to perform different operations through different terminal lists, such as selecting a terminal as a reader or allocating resources for a terminal to be used as a reader. This enables the second network-side device to accurately identify which terminal needs to be selected as a reader or which needs to be allocated resources for that terminal.

[0415] In some embodiments of this application, the aforementioned fourth information can be determined by the subscription, the location of the UE, or the information carried in the AIoT operation request. For example, the fourth information may be carried in the AIoT operation, or the AIoTF may determine the fourth information based on the UE's subscription information as a reader / writer.

[0416] In some embodiments of this application, the first terminal list may satisfy at least one of the following: the first terminal list is a candidate reader / writer list; the first terminal list is used to select one or more terminals as readers / writers; the first terminal list includes information about one or more terminals, and the terminals are candidates for readers / writers.

[0421] The communication method provided in this application allows the second network-side device to perform different operations through different terminal lists, such as selecting a terminal as a reader or allocating resources for a terminal to be used as a reader. This enables the second network-side device to accurately identify which terminal needs to be selected as a reader or which needs to be allocated resources for that terminal.
