For those skilled in the art, the specific meaning of the above terms in the embodiments of the application can be understood according to the specific circumstances.

[0229] First, the AIoT device involved in the related art will be described below.

[0230] Ambient Internet of Things (AIoT) is a new emerging Internet of Things technology. AIoT devices generally refer to devices that have no energy or only have very limited energy, and communicate by obtaining energy from the external environment. For example, AIoT devices can include Radio Frequency Identification (RFID) devices.

[0231] AIoT devices often have no energy or only have very limited energy, generally have very low complexity and cost, have very small data transmission volume (for example, only need to report tag information) and very low frequency (for example, may only transmit data once).

[0232] The data transmission mechanism of the terminal in the related art is described.

[0233] In the related art, the data transmission mechanism of the terminal requires the terminal to actively initiate a registration process to register in the network and establish a Protocol Data Unit (PDU) session, and then the terminal can perform data transmission. The network needs to maintain the context information of each terminal. For NB-IoT devices, small data transmission can be optimized by control plane small data transmission, but all of them need to register and establish a PDU session before performing.

[0234] In the present application, in order to solve the problem that it cannot be determined how to control the terminal to interact with the AIoT device in the related art, a communication method, device, apparatus and storage medium are proposed. The Access Mobility Management Function (AMF) network element or the Ambient Internet of Things (AIoT) function network element receives a first request message sent by a Network Exposure Function (NEF) network element, the first request message being used to indicate that a terminal performs a business operation on an AIoT device, and the first request message including location information of the AIoT device. Then, the terminal that performs the business operation on the AIoT device is determined according to the location information of the AIoT device. Finally, the first request message is sent to the terminal or an access network device corresponding to the terminal. Since the AMF network element or the AIoT function network element determines the terminal that performs the business operation on the AIoT device by using the location information of the AIoT device and the registration location information of the candidate terminal when receiving the first request message, and sends the first request message to the terminal or the access network device corresponding to the terminal, the terminal performs the business operation on the AIoT device according to the first request message, thereby realizing the control of the interaction between the terminal and the AIoT device.

[0235] The application scenario of the communication method provided in the present application is described below.

As shown in FIG. 1, a terminal 101 is connected with an AIoT device 102 and a network device 103 respectively. When the network device 103 needs to instruct the terminal 101 to perform a service operation on the AIoT device 102, the network device 103 can determine the terminal 101 corresponding to the AIoT device 102. Then, the network device 103 sends a first request message to the terminal 101, where the first request message is used to instruct the terminal 101 to perform a service operation on the AIoT device 102. Then, the terminal 101 performs a service operation on the AIoT device 102 based on the first request message.

As shown in FIG. 2, the above communication method can be used to realize the interaction between the network and the AIoT device during the cargo warehouse-in and warehouse-out.

[0243] The technical solutions in the embodiments of the present application will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0244] In one embodiment, as shown in FIG. 3, a flowchart of a communication method is provided, which is used to illustrate the process of how to control the interaction between the terminal and the AIoT device. The communication method includes S201-S203:

[0245] S201, the NEF network element sends a first request message to the AMF network element or the passive Internet of Things function network element.

[0246] The first request message is used to instruct the terminal to perform a service operation on the passive IoT device, and the first request message includes location information of the passive IoT device.

[0247] In some embodiments, an Application Function (AF) network element can send a first request message to a NEF network element, and then the NEF network element can send the first request message to an AMF network element or a passive IoT function network element after receiving the first request message.

[0248] In some embodiments, the first request message includes service operation indication information, which is used to indicate the service operation performed by the terminal on the passive IoT device.

[0249] For example, the service operation indication information includes inventory operation indication information and command operation indication information, the inventory operation indication information is used to instruct the passive IoT device to report identification information, and the command operation indication information is used to instruct a data reading operation, a data writing operation, an enabling operation, or a disabling operation on the passive IoT device.

[0250] In some embodiments, if the service operation indication information includes the command operation indication information, the first request message further includes associated data for the reading operation or the data writing operation on the passive IoT device.

[0251] For example, if the service operation is a Command task, the associated data in the first request message can include Read, Write, enable / disable parameters and data to be written.

[0252] In some embodiments, the first request message described above can indicate a service operation on a single AIoT device, or a service operation on multiple AIoT devices. Correspondingly, the location information described above can be the location of a single AIoT device, or the location range of multiple AIoT devices.

[0253] In some embodiments, the first request message can include identification information of the AIoT device and identification information of the AF network element, in addition to the location information of the passive IoT device.

[0254] In some embodiments, the first request message further includes auxiliary information of the service operation. The auxiliary information includes at least one of the following: execution duration of the service operation; execution period of the service operation; data aggregation indication information; communication distance requirement between the terminal and the passive IoT device; communication delay requirement between the passive IoT devices; and movement restriction information of the terminal.

[0255] The mobility restriction information of the terminal can limit the movement of the terminal in a specific cell or routing area (RA).

[0256] It should be understood that the embodiments of the present application do not limit how the NEF network element sends the first request message to the AMF network element or the passive Internet of Things function network element.

[0257] In some embodiments, before the NEF network element sends the first request message to the AMF network element or the passive Internet of Things function network element, the NEF network element can also perform authorization checking on the first request message sent by the AF network element. The NEF network element can determine the AMF network element or the passive Internet of Things function network element that performs the service operation of the AIoT device based on the location information of the AIoT device. Then, the NEF network element sends the first request message to the AMF network element or the passive Internet of Things function network element.

[0258] S202, the AMF network element or the passive Internet of Things function network element determines the terminal that performs the service operation of the passive Internet of Things device according to the location information of the passive Internet of Things device and the registration location information of the candidate terminal.

[0259] In this step, when the AMF network element or the passive Internet of Things function network element receives the first request message, it can determine the terminal that performs the service operation of the passive Internet of Things device according to the location information of the passive Internet of Things device.

[0260] It should be understood that the embodiments of the present application do not limit how the passive Internet of Things device is determined according to the location information of the passive Internet of Things device. In some embodiments, the AMF network element or the passive Internet of Things function network element can determine the terminal that performs the service operation of the passive Internet of Things device from the candidate terminal according to the location information of the passive Internet of Things device and the registration location information of the candidate terminal.

[0261] For example, after the access network device establishes a connection with the candidate terminal, it can send the registration location information of the candidate terminal to the AMF network element or the passive Internet of Things function network element. The AMF network element or the passive Internet of Things function network element can match the current registration location information of multiple candidate terminals with the location information of the AIoT device to determine the candidate terminal in the location area of the AIoT device. Then, the candidate terminal that matches successfully can be determined as the terminal that performs the service operation of the passive Internet of Things device, and an identification list of the terminal is generated.

[0262] In some embodiments, the AMF network element or the passive Internet of Things function network element can add the identification list of the terminal in the first request message.

[0263] The candidate end can be a terminal that has registered in an AMF network element or a passive Internet of Things function network element to allow the terminal to act as a relay node. The registration location information can be a location of a cell in which the candidate end is registered.

[0264] It should be understood that the embodiments of the present application do not limit how the terminal registers. In some embodiments, the terminal can send a third request message to an AMF network element or a passive Internet of Things function network element. Subsequently, the AMF network element or the passive Internet of Things function network element sends a third response message to the terminal, and the third response message is used to indicate that the AMF network element or the passive Internet of Things function network element or an access network device allows the terminal to communicate with the passive Internet of Things device. The AMF network element or the passive Internet of Things function network element adds the third response message in the context information of the terminal.

[0265] In some embodiments, after allowing the terminal to communicate with the passive Internet of Things device, the AMF network element or the passive Internet of Things function network element can also send the third response message to the access network device through an N2 message.

[0266] S203, the AMF network element or the passive Internet of Things function network element sends a first request message to the terminal or an access network device corresponding to the terminal.

[0267] In this step, when the AMF network element or the passive Internet of Things function network element determines the terminal corresponding to the first request message, the AMF network element or the passive Internet of Things function network element can send the first request message to the terminal or the access network device corresponding to the terminal.

[0268] In some embodiments, the AMF network element or the passive Internet of Things function network element can first send the first request message to the access network device corresponding to the terminal, and then the access network device corresponding to the terminal sends the first request message to the terminal. Finally, the terminal performs a target task business operation on the passive Internet of Things device based on the first request message, and sends a second request message to the passive Internet of Things device.

[0269] The second request is used to indicate a business operation performed by the terminal on the passive Internet of Things device, and the second request message contains identification information of the passive Internet of Things device.

[0270] Correspondingly, if the AMF network element or the passive Internet of Things function network element sends the first request message to the access network device corresponding to the terminal, the AMF network element or the passive Internet of Things function network element can send the first request message to the terminal through at least one of an access layer and a non-access layer.

[0271] Exemplarily, FIG. 4 is a schematic diagram of a protocol stack provided by an embodiment of the present application. As shown in FIG. 4, in the process of sending the first request message by the AMF network element or the passive Internet of Things function network element to the access network device, the first request message can be carried in an N2 message. In the process of sending the first request message by the access network device to the terminal, the first request message can be carried in an access layer message. In the process of sending the second request message by the terminal to the AIoT device, the second request message can be carried in an access layer message. With reference to FIG. 4, the message can also be carried in a non-access layer message between the AIoT device and the AMF network element or the passive Internet of Things function network element.

[0272] The access layer message can include a radio resource control (RRC).

[0273] In some embodiments, after the access network device receives the first request message, the access network device can also send the first request message to the terminal that performs the service operation on the passive Internet of Things device according to the camping location information and the identity list of the terminal.

[0274] Exemplarily, the access network device can further screen the terminal from the identity list by the camping location information of the terminal, so as to screen the terminal that performs the service operation on the passive Internet of Things device again, and then send the first request message to the terminal that performs the service operation on the passive Internet of Things device, so that the terminal that performs the service operation on the passive Internet of Things device sends the second request message to the passive Internet of Things device.

[0275] In the present application, the terminal is screened again by the access network device through the camping location information of the terminal, so that the terminal that performs the service operation on the passive Internet of Things device can be determined more accurately.

[0276] In some embodiments, the AMF network element or the passive Internet of Things function network element can send the first request message to the terminal, and then the terminal performs the service operation on the passive Internet of Things device, and subsequently, the second request message is sent to the passive Internet of Things device.

[0277] Correspondingly, if the first request message is sent to the terminal by the access network device, the AMF network element or the passive Internet of Things function network element can send the first request message to the access network device corresponding to the terminal through an N2 interface.

[0278] Exemplarily, FIG. 5 is a schematic diagram of another protocol stack provided by an embodiment of the present application. As shown in FIG. 4, in the process of sending the first request message by the AMF network element or the passive Internet of Things function network element to the terminal, the first request message can be carried in at least one of an access layer message and a non-access layer message. In the process of sending the second request message by the terminal to the AIoT device, the message can be carried in a non-access layer message.

[0279] In some embodiments, the first request message further comprises assistance information for the terminal to perform the service operation, and the assistance information comprises at least one of: an execution duration of the service operation; an execution period of the service operation; data aggregation indication information; a communication distance requirement between the terminal and the passive Internet of Things device; a communication delay requirement of the passive Internet of Things device; and movement restriction information of the terminal.

[0280] Correspondingly, when the terminal receives the first request message, the terminal can configure the service operation according to the assistance information in the first request message.

[0281] For example, the terminal can determine the transmission power of the service operation to the passive Internet of Things device according to the communication distance requirement between the terminal and the passive Internet of Things device.

[0282] For example, the terminal can determine the movement range of the terminal according to the movement restriction information of the terminal. That is, the terminal determines the movable cell or routing area based on the movement restriction information.

[0283] For example, the terminal can determine the time length and frequency of each service operation according to the execution duration and the execution period of the service operation.

[0284] It should be understood that the embodiments of the present application do not limit how the terminal performs the service operation on the passive Internet of Things device according to the first request message. In some embodiments, the terminal can send a second request message to the passive Internet of Things device, the second request message being used to indicate the service operation performed by the terminal on the passive Internet of Things device, and the second request message comprising identification information of the passive Internet of Things device. After the passive Internet of Things device completes the service operation, the passive Internet of Things device can send a second response message to the terminal, the second response message comprising at least one of the identification information of the passive Internet of Things device and the execution result of the service operation in the second request message.

[0285] For example, when the passive Internet of Things device receives the second request message and performs the service operation, the passive Internet of Things device can initiate a random access process. Subsequently, the passive Internet of Things device can send a second response message to the terminal. The terminal can send the first response message to the AMF network element or the passive Internet of Things function network element or the access network device.

[0286] It should be understood that the embodiments of the present application do not limit the first response message. In some embodiments, the first response message comprises at least one of the execution result of the service operation indicated by the request message and the identification information of the passive Internet of Things device.

[0287] The execution result of the service operation can include the result of write, the data of read, the result of enable or disable, and the like.

[0288] Exemplarily, the terminal can also verify the identification information of the passive Internet of Things device in the second response message. If the verification is correct, the terminal sends the first response message to the AMF network element or the passive Internet of Things function network element or the access network device.

[0289] In some embodiments, if the access network device receives the first response message, the identification information of the passive Internet of Things device in the first response message can also be verified. If the verification is correct, the access network device sends the first response message to the AMF network element or the passive Internet of Things function network element.

[0290] In some embodiments, the AMF network element or the passive Internet of Things function network element can also verify the identification information of the passive Internet of Things device in the first response message after receiving the first response message. If the verification is correct, the first response message is sent to the NEF network element. Subsequently, the NEF network element can send the first response message to the AF network element.

[0291] In some embodiments, if the passive Internet of Things data aggregation indication information indicates that the first response messages sent by multiple passive Internet of Things devices are aggregated, the terminal can aggregate the identification information and the execution results sent by multiple passive Internet of Things devices. Subsequently, the aggregated identification information and the execution results are sent to the AMF network element or the passive Internet of Things function network element or the access network device through the first response message.

[0292] Exemplarily, if the second request message is sent to multiple passive Internet of Things devices, each passive Internet of Things device can send a second response message to the terminal. Correspondingly, the terminal can determine whether to aggregate the second response messages according to the data aggregation indication information in the auxiliary information. If it is indicated that the second response messages are aggregated, the terminal can determine the aggregation time according to the communication delay requirement between the passive Internet of Things device and the AF.

[0293] Correspondingly, if the first request message indicates the communication delay requirement of the passive Internet of Things device, the first response message is sent to the MF network element or the passive Internet of Things function network element or the access network device under the requirement of the communication delay.

[0294] The communication method provided in the embodiments of the present application comprises the following steps: an access mobility management function (AMF) network element or a passive Internet of Things function network element receives a first request message sent by a network exposure function (NEF) network element, the first request message is used to instruct a terminal to perform a service operation on a passive Internet of Things device, and the first request message comprises location information of the passive Internet of Things device; then, the terminal performing the service operation on the passive Internet of Things device is determined according to the location information of the passive Internet of Things device and registration location information of a candidate terminal; finally, the first request message is sent to the terminal or an access network device corresponding to the terminal. Since the AMF network element or the passive Internet of Things function network element determines the terminal performing the service operation on the passive Internet of Things device according to the location information of the passive Internet of Things device when receiving the first request message, and sends the first request message to the terminal or the access network device corresponding to the terminal, so that the terminal performs the service operation on the passive Internet of Things device according to the first request message, the control over the interaction between the terminal and the AIoT device is realized.

[0295] The following describes different manners of sending the first request message.

[0296] In some cases, the AMF network element or the passive Internet of Things function network element can send the first request message to the terminal through the access network device.
