[0043] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0044] The following is an explanation of some professional terms in the embodiments of the present application:

[0045] Ambient IoT (AIoT): With the help of mobile communication networks, passive IoT devices can achieve zero or low power communication through technologies such as RF energy harvesting, backscattering, and low-power computing.

[0046] Ambient power-enabled Internet Function (AIoTF): A network element with artificial intelligence processing capabilities and IoT data management functions, which can deeply integrate artificial intelligence technology with IoT communication technology. It aims to efficiently process, analyze and make decisions on the massive data generated by IoT devices, and at the same time realize intelligent management and control of IoT devices; AIoTF is usually located on the core network side, between the application function network element and the wireless access network. As a part of the core network, it can work with other network elements to realize efficient transmission and processing of IoT data.

[0047] In an exemplary embodiment, Figure 1 As shown, a passive Internet of Things information transmission method is provided. This embodiment uses the method applied to a passive Internet of Things functional network element of an Internet of Things transmission system as an example. In this embodiment, the method includes the following steps:

[0048] Step 102: If service request information sent by an application function network element of the Internet of Things transmission system is received, a first message container identifier corresponding to the service request information is obtained.

[0049] The passive IoT information transmission method of the embodiment of the present application can be applied to an IoT transmission system, which may include but is not limited to a passive IoT function network element AIoTF, an access and mobility management function network element (Access and Mobility Management Function, AMF), a passive IoT terminal, an application function network element (Application Function, AF), a wireless access network device and an IoT transmission interface. In a possible implementation, the information transmission of the IoT transmission system can be implemented by Figure 2 The topology 1 shown is implemented, and the topology 1 is a passive IoT information transmission topology structure of the IoT transmission system. The IoT transmission interface may include three interfaces, Nx, Ny, and Nz. The wireless access network device may be recorded as (Ambient IoT Radio Access Network, AIoTRAN), Nx may be the interface between the passive IoT function network element AIoTF and AIoT RAN; Ny may be the interface between the passive IoT function network element AIoTF and the passive IoT terminal; Nz may be the interface between the passive IoT function network element AIoTF and the access and mobility management function network element AMF; N 2 It is the interface between AMF and NG RAN. In another possible implementation, the information transmission of the IoT transmission system can be implemented by Figure 3The topology 2 shown is implemented, and the topology 2 is another passive IoT information transmission topology structure of the IoT transmission system. Among them, the IoT transmission interface may include three interfaces Nx, Ny, and Nz. The wireless access network device may be recorded as (Next Generation Radio Access Network, NG RAN), Nx may be the interface between the passive IoT function network element AIoTF and NG RAN; Ny may be the interface between the passive IoT function network element AIoTF and the passive IoT terminal; Nz may be the interface between the passive IoT function network element AIoTF and the access and mobility management function network element AMF. In addition, the user reader may be recorded as UEReader; the user plane function (UE) is the main component of the user plane of the core network, responsible for processing the data transmission between the user equipment (UE) and the external data network (for example, the Internet, the enterprise intranet, etc.), and is a bridge connecting the core network and the external network, mainly responsible for the forwarding of data packets, routing selection, policy execution and other functions; the artificial intelligence of things access point (AIoT-AP) is a device with artificial intelligence processing capabilities and wireless access functions; N 1 It is the interface between AMF and the user reader. 2It is the interface between AMF and NGRAN. In this step, when the passive Internet of Things function network element AIoTF receives the service request information sent by the application function network element, it can encapsulate the service request information according to the transmission format to generate downlink non-access layer transmission information, and the downlink non-access layer transmission information can include a message header, a payload and a payload container type information element, that is, a first message container identifier. The message header can cover the basic information of the message, such as the message type, the message length, the protocol version, etc. This information helps the receiver to preliminarily identify and process the message; the payload can be the core part of the message, carrying the actual data to be uploaded by the terminal device. In the AIoT data transmission scheme, the payload may contain various data related to AIoT, such as device status information, data collected by sensors, etc. The payload can also include an application function network element identifier, a reader identifier, a passive Internet of Things terminal identifier, a task identifier, a task area and a task requirement, etc.; the payload container type information element can indicate the type of the payload, especially the newly added AIoT identifier. When the element is identified as AIoT, it indicates that the payload carries AIoT related information. The service request information is encapsulated in the payload container of the downlink non-access layer transmission information, and the passive Internet of Things functional network element AIoTF can set the first message container identifier of the downlink non-access layer transmission information to the passive Internet of Things identifier, for example, AIoT. The first message container identifier can be used to indicate the container type of the downlink non-access layer transmission information payload container. Setting the first message container identifier to the passive Internet of Things identifier can indicate that the service request information encapsulated in the downlink non-access layer transmission information is AIoT information.

[0050] Step 104: if the first message container identifier is a passive Internet of Things identifier, the service request information is transmitted to the passive Internet of Things terminal of the Internet of Things transmission system through the Internet of Things transmission interface of the Internet of Things transmission system.

[0051] Among them, the passive Internet of Things functional network element AIoTF can transmit the downlink non-access layer transmission information marked with the passive Internet of Things identifier to the passive Internet of Things terminal of the Internet of Things transmission system through the Internet of Things transmission interface of the Internet of Things transmission system, and the downlink non-access layer transmission information includes service request information. The Internet of Things transmission interface may include multiple interfaces, for example, Nx, Ny, and Nz interfaces. Different Internet of Things transmission interfaces correspond to different transmission modes. The passive Internet of Things functional network element AIoTF can select the corresponding transmission mode according to the Internet of Things transmission interface to transmit the downlink non-access layer transmission information containing the service request information to the passive Internet of Things terminal of the Internet of Things transmission system.

[0052] Step 106: Receive service feedback information for the service request information through the Internet of Things transmission interface, and send the service feedback information to the application function network element.

[0053] The passive Internet of Things terminal receives the service request information from the application function network element, and can respond to the service request information to obtain service feedback information of the service request information. The service request information can be a service request initiated to the passive Internet of Things terminal, such as environmental monitoring and data collection. The service feedback information can be response information to the service request information, such as monitored environmental information.

[0054] In the method of this embodiment, if the passive Internet of Things functional network element of the Internet of Things transmission system receives the service request information sent by the application function network element of the Internet of Things transmission system, it obtains the first message container identifier corresponding to the service request information; if the first message container identifier is a passive Internet of Things identifier, the service request information is transmitted to the passive Internet of Things terminal of the Internet of Things transmission system through the Internet of Things transmission interface of the Internet of Things transmission system; service feedback information for the service request information is received through the Internet of Things transmission interface, and the service feedback information is sent to the application function network element. In the method provided by the embodiment of the present application, an Internet of Things transmission interface is newly added to the Internet of Things transmission system. When the message container identifier corresponding to the service request information and / or the service feedback information is a passive Internet of Things identifier, the service request information and / or the service feedback information can be transmitted through the Internet of Things transmission interface. Different Internet of Things transmission interfaces correspond to different transmission nodes and transmission modes, which can improve the transmission efficiency of passive Internet of Things information, and can quickly identify whether the service request information and / or the service feedback information is passive Internet of Things information according to the passive Internet of Things identifier, which can further improve the transmission efficiency of passive Internet of Things information.

[0055] In an exemplary embodiment, before step 102, the following may also be included:

[0056] Receive service request information sent by the application function network element, generate downlink non-access layer transmission information corresponding to the service request information; set the first message container identifier of the downlink non-access layer transmission information to the passive Internet of Things identifier.

[0057] When the passive Internet of Things functional network element AIoTF receives the service request information sent by the application functional network element, it can encapsulate the service request information according to the transmission format to generate downlink non-access layer transmission information. The downlink non-access layer transmission information may include a message header, a payload and a payload container type information element, i.e., a first message container identifier. The message header may cover basic information of the message, such as message type, message length, protocol version, etc., which helps the receiver to preliminarily identify and process the message; the payload (i.e., the service request information) may be the core part of the message, carrying the actual data to be uploaded by the terminal device. In the AIoT data transmission scheme, the payload may contain various AIoT-related data, such as device status information, data collected by sensors, etc. The payload may also include an application functional network element identifier, a reader identifier, a passive Internet of Things terminal identifier, a task identifier, a task area, and task requirements, etc.; the payload container type information element (i.e., the first message container identifier) ​​can indicate the type of the payload, especially the newly added AIoT identifier. When the element identifier, i.e., the first message container identifier is AIoT, it indicates that the payload carries AIoT-related information. The service request information is encapsulated in the payload container of the downlink non-access layer transmission information, and the passive Internet of Things functional network element AIoTF can set the first message container identifier of the downlink non-access layer transmission information to the passive Internet of Things identifier, for example, AIoT. The first message container identifier can be used to indicate the container type of the downlink non-access layer transmission information payload container. Setting the first message container identifier to the passive Internet of Things identifier can indicate that the service request information encapsulated in the downlink non-access layer transmission information is AIoT information.

[0058] In the method of this embodiment, whether the service request information and / or service feedback information is passive Internet of Things information can be quickly identified based on the passive Internet of Things identifier, which can further improve the transmission efficiency of the passive Internet of Things information.

[0059] In an exemplary embodiment, Figure 4 As shown, step 104 may include:

[0060] If the first message container identifier is a passive Internet of Things identifier, transmitting the service request information to the access and mobility management network element through the first transmission interface;

[0061] Among them, the access and mobility management network element is used to forward service request information to the passive Internet of Things terminal through the transfer device.

[0062] In this implementation, if the first message container identifier corresponding to the downlink non-access layer transmission information containing the service request information is a passive Internet of Things identifier, it can be transmitted to the passive Internet of Things terminal of the Internet of Things transmission system through the Internet of Things transmission interface of the Internet of Things transmission system. The Internet of Things transmission interface may include multiple interfaces, and the multiple interfaces may include but are not limited to a first transmission interface (Nz), a second transmission interface (Nx) and a third transmission interface (Ny), wherein the first transmission interface may be an interface between a passive Internet of Things functional network element AIoTF and an access and mobility management functional network element AMF. If the Internet of Things transmission interface is the first transmission interface, the passive Internet of Things functional network element AIoTF can send the downlink non-access layer transmission information containing the service request information to the access and mobility management function network element AMF through the first transmission interface. Next, the access and mobility management function network element AMF can forward the downlink non-access layer transmission information containing the service request information to the transfer device. The transfer device can be a wireless access network device. The wireless access network device can include but is not limited to a base station, a base station reader and a relay terminal reader. The transfer device can parse the received downlink non-access layer transmission information, obtain the first message container identifier of the downlink non-access layer transmission information and the corresponding passive Internet of Things terminal identifier. If the first message container identifier is a passive Internet of Things identifier, the passive Internet of Things terminal corresponding to the passive Internet of Things terminal identifier is awakened, and the downlink non-access layer transmission information is sent to the passive Internet of Things terminal.

[0063] In an exemplary embodiment, Figure 4 As shown, step 106 may include:

[0064] Receiving, via the first transmission interface, uplink non-access layer transmission information including service feedback information forwarded by an access and mobility management network element;

[0065] Among them, the access and mobility management network element is used to receive the uplink non-access layer transmission information sent by the transit device, and when the second message container identifier of the uplink non-access layer transmission information is a passive Internet of Things identifier, forward the uplink non-access layer transmission information to the passive Internet of Things functional network element.

[0066] Specifically, the passive Internet of Things terminal can respond to the downlink non-access layer transmission information, generate service feedback information for the service request information, and send the service feedback information to the transit device. Then, the transit device can encapsulate the service feedback information to generate uplink non-access layer transmission information. The uplink non-access layer transmission information may include a message header, a payload, and a payload container type information element, i.e., a second message container identifier. The message header may cover basic information of the message, such as message type, message length, protocol version, etc. This information helps the receiver to preliminarily identify and process the message; the payload (i.e., service feedback information) may be the core part of the message, carrying the actual data to be uploaded by the terminal device. In the AIoT data transmission scheme, the payload may contain various AIoT-related data, such as device status information, data collected by sensors, etc.; the payload container type information element (i.e., the second message container identifier) ​​can indicate the type of the payload, especially the newly added AIoT identifier. When the element identifier, i.e., the second message container identifier is AIoT, it indicates that the payload carries AIoT-related information. The service feedback information is encapsulated in the payload container of the uplink non-access layer transmission information, and the transit device can set the second message container identifier of the uplink non-access layer transmission information to a passive Internet of Things identifier, for example, an AIoT identifier. The second message container identifier can be used to indicate the container type of the uplink non-access layer transmission information payload container. Setting the second message container identifier to a passive Internet of Things identifier can indicate that the service feedback information encapsulated in the uplink non-access layer transmission information is AIoT information. Next, the transit device can send the uplink non-access layer transmission information to the access and mobility management function network element AMF. If the second message container identifier of the uplink non-access layer transmission information is a passive Internet of Things identifier, the access and mobility management function network element AMF can send the uplink non-access layer transmission information to the passive Internet of Things function network element AIoTF through the first transmission interface. The passive Internet of Things function network element AIoTF can parse the uplink non-access layer transmission information to obtain the contained service feedback information, and send the service feedback information to the application function network element.

[0067] In the method of this embodiment, if the Internet of Things transmission interface is the first transmission interface, the passive Internet of Things functional network element AIoTF can send the downlink non-access layer transmission information containing the service request information to the access and mobility management functional network element AMF through the first transmission interface, and then transmit it to the passive Internet of Things terminal, which can improve the transmission efficiency of the passive Internet of Things information.

[0068] In another exemplary embodiment, Figure 5 As shown, step 104 may include:

[0069] If the first message container identifier is a passive Internet of Things identifier, the service request information is transmitted to the transfer device through the second transmission interface;

[0070] Among them, the transfer device is used to forward the service request information to the passive Internet of Things terminal.

[0071] In this implementation, if the first message container identifier corresponding to the downlink non-access layer transmission information containing the service request information is a passive Internet of Things identifier, it can be transmitted to the passive Internet of Things terminal of the Internet of Things transmission system through the Internet of Things transmission interface of the Internet of Things transmission system. The Internet of Things transmission interface may include multiple interfaces, and the multiple interfaces may include but are not limited to a first transmission interface (Nz), a second transmission interface (Nx) and a third transmission interface (Ny), wherein the second transmission interface may be an interface between a passive Internet of Things functional network element AIoTF and a transfer device, and the transfer device may be a wireless access network device, and the wireless access network device may include but is not limited to a base station, a base station reader and a relay terminal reader. If the Internet of Things transmission interface is the second transmission interface, the passive Internet of Things functional network element AIoTF can send the downlink non-access layer transmission information containing the service request information to the transfer device through the second transmission interface. Next, the transfer device can parse the received downlink non-access layer transmission information, obtain the first message container identifier of the downlink non-access layer transmission information and the corresponding passive Internet of Things terminal identifier. If the first message container identifier is a passive Internet of Things identifier, the passive Internet of Things terminal corresponding to the passive Internet of Things terminal identifier is woken up, and the downlink non-access layer transmission information is sent to the passive Internet of Things terminal.

[0072] In an exemplary embodiment, Figure 5 As shown, step 106 may include:

[0073] Receiving, via the second transmission interface, uplink non-access layer transmission information including service feedback information sent by the transfer device;

[0074] Among them, the transfer device is used to receive service feedback information sent by the passive Internet of Things terminal, generate uplink non-access layer transmission information corresponding to the service feedback information, and set the second message container identifier of the uplink non-access layer transmission information to the passive Internet of Things identifier.

[0075] Specifically, the passive Internet of Things terminal can respond to the downlink non-access layer transmission information, generate service feedback information for the service request information, and send the service feedback information to the transit device. Then, the transit device can encapsulate the service feedback information to generate uplink non-access layer transmission information. The uplink non-access layer transmission information may include a message header, a payload, and a payload container type information element, i.e., a second message container identifier. The message header may cover basic information of the message, such as message type, message length, protocol version, etc. This information helps the receiver to preliminarily identify and process the message; the payload (i.e., service feedback information) may be the core part of the message, carrying the actual data to be uploaded by the terminal device. In the AIoT data transmission scheme, the payload may contain various AIoT-related data, such as device status information, data collected by sensors, etc.; the payload container type information element (i.e., the second message container identifier) ​​can indicate the type of the payload, especially the newly added AIoT identifier. When the element identifier, i.e., the second message container identifier is AIoT, it indicates that the payload carries AIoT-related information. The service feedback information is encapsulated in the payload container of the uplink non-access layer transmission information, and the transit device can set the second message container identifier of the uplink non-access layer transmission information to a passive Internet of Things identifier, for example, an AIoT identifier. The second message container identifier can be used to indicate the container type of the uplink non-access layer transmission information payload container. Setting the second message container identifier to a passive Internet of Things identifier can indicate that the service feedback information encapsulated in the uplink non-access layer transmission information is AIoT information. Next, the transit device can send the uplink non-access layer transmission information to the passive Internet of Things functional network element AIoTF through the second transmission interface. If the second message container identifier of the uplink non-access layer transmission information is a passive Internet of Things identifier, the passive Internet of Things functional network element AIoTF can parse the uplink non-access layer transmission information, obtain the contained service feedback information, and send the service feedback information to the application functional network element.

[0076] In the method of this embodiment, if the Internet of Things transmission interface is the second transmission interface, the passive Internet of Things functional network element AIoTF can send the downlink non-access layer transmission information containing the service request information to the transit device through the second transmission interface, and then transmit it to the passive Internet of Things terminal, which can improve the transmission efficiency of the passive Internet of Things information.

[0077] In yet another exemplary embodiment, Figure 6 As shown, step 104 may include:

[0078] If the first message container identifier is a passive Internet of Things identifier, the service request information is transmitted to the passive Internet of Things terminal through the third transmission interface.

[0079] Specifically, if the first message container identifier corresponding to the downlink non-access layer transmission information containing the service request information is a passive Internet of Things identifier, it can be transmitted to the passive Internet of Things terminal of the Internet of Things transmission system through the Internet of Things transmission interface of the Internet of Things transmission system. The Internet of Things transmission interface may include multiple interfaces, and the multiple interfaces may include but are not limited to a first transmission interface (Nz), a second transmission interface (Nx) and a third transmission interface (Ny), wherein the third transmission interface may be an interface between a passive Internet of Things functional network element AIoTF and a passive Internet of Things terminal. If the Internet of Things transmission interface is a second transmission interface, the passive Internet of Things functional network element AIoTF can send the downlink non-access layer transmission information containing the service request information to the passive Internet of Things terminal through the second transmission interface.

[0080] In an exemplary embodiment, Figure 6 As shown, step 106 may include:

[0081] Receiving, via a third transmission interface, uplink non-access layer transmission information including service feedback information sent by a passive Internet of Things terminal;

[0082] Among them, the passive Internet of Things terminal is used to respond to the service request information, obtain the service feedback information corresponding to the service request information, generate the uplink non-access layer transmission information corresponding to the service feedback information, and set the second message container identifier of the uplink non-access layer transmission information to the passive Internet of Things identifier.

[0083] Specifically, the passive Internet of Things terminal can respond to the downlink non-access layer transmission information, generate service feedback information for the service request information, and can encapsulate the service feedback information to generate uplink non-access layer transmission information. The uplink non-access layer transmission information may include a message header, a payload, and a payload container type information element, that is, a second message container identifier. The message header may cover basic information of the message, such as message type, message length, protocol version, etc. This information helps the receiver to preliminarily identify and process the message; the payload (that is, the service feedback information) may be the core part of the message, carrying the actual data to be uploaded by the terminal device. In the AIoT data transmission scheme, the payload may contain various AIoT-related data, such as device status information, data collected by sensors, etc.; the payload container type information element (that is, the second message container identifier) ​​can indicate the type of the payload, especially the newly added AIoT identifier. When the element identifier, that is, the second message container identifier is AIoT, it indicates that the payload carries AIoT-related information. The service feedback information is encapsulated in the payload container of the uplink non-access layer transmission information, and the transit device can set the second message container identifier of the uplink non-access layer transmission information to a passive Internet of Things identifier, for example, an AIoT identifier. The second message container identifier can be used to indicate the container type of the uplink non-access layer transmission information payload container. Setting the second message container identifier to a passive Internet of Things identifier can indicate that the service feedback information encapsulated in the uplink non-access layer transmission information is AIoT information. Next, the passive Internet of Things terminal can send the uplink non-access layer transmission information to the passive Internet of Things functional network element AIoTF through the third transmission interface. If the second message container identifier of the uplink non-access layer transmission information is a passive Internet of Things identifier, the passive Internet of Things functional network element AIoTF can parse the uplink non-access layer transmission information, obtain the contained service feedback information, and send the service feedback information to the application functional network element.

[0084] In the method of this embodiment, if the Internet of Things transmission interface is the third transmission interface, the passive Internet of Things functional network element AIoTF can send the downlink non-access layer transmission information containing the service request information to the passive Internet of Things terminal through the third transmission interface, thereby improving the transmission efficiency of the passive Internet of Things information.
