[0002] In existing technologies, when a network and a gateway are connected, the network cannot know the devices behind the gateway, meaning that devices behind the gateway cannot be recognized by the network. However, in some specific scenarios, such as personal IoT scenarios, when a device behind the gateway needs to access the 5G network through the gateway and be recognized by the 5G network, the Session Management Function (SMF) corresponding to the gateway's session needs to be notified that a device is connected to the gateway so that the SMF can initiate the corresponding signaling process.

[0083] The information transmission method, apparatus, and network functions provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0084] like Figure 2 As shown in the figure, this application provides an information transmission method, including:

[0085] Step 201: The first network function obtains the first information;

[0086] It should be noted that the first information is related to the first terminal, and optionally, the first information includes at least one of the following:

[0087] A11, Capability Indication, used to indicate that the first terminal has gateway capabilities;

[0088] A12, Type Indication, used to indicate that the first terminal is a gateway device;

[0089] A13. Session indication, used to indicate that the session between the first terminal and the network is for forwarding;

[0090] A14. Data network access information, used to indicate that the first terminal is used for data forwarding, the first terminal has gateway capabilities, the first terminal is a gateway device, or the session of the first terminal is used for forwarding.

[0091] It should be noted that the data network access information can be a data network access identifier (DNAI) or a DNAI name.

[0092] Step 202: The first network function sends a subscription request for the first event to the second network function based on the first information;

[0093] It should be noted that the first event may specifically refer to a relationship event (connection event); specifically, the first event is used to instruct the second network function to send a relationship notification related to the first terminal when the first triggering condition is met;

[0094] Optionally, the first triggering condition includes at least one of the following:

[0095] A21. The first terminal forwards data;

[0096] A22. The first terminal adds a member;

[0097] A23. The first terminal adds a forwarding object.

[0098] It should be noted that in this embodiment, the first network function sends a subscription request to the second network function, so that the second network function sends a relationship notification to the first network function when the first triggering condition is met, so that the first network function can clearly understand the access status of the devices (or members) under the first terminal, thereby ensuring the reliability of data transmission.

[0099] It should be noted that the above-mentioned limitation on the first triggering condition is only able to distinguish changes in devices (or members) under the first terminal. However, if multiple devices (or members) simultaneously connect or leave under the first device, in order to clearly enable the first network function to know which devices (or members) caused the change, the first triggering condition may optionally include at least one of the following:

[0100] B11. The first terminal forwards data from the second terminal;

[0101] B12. The first terminal stops forwarding data from the second terminal;

[0102] B13. The first terminal adds the second terminal as a member;

[0103] B14. The first terminal removes the second terminal as a member;

[0104] B15. The first terminal adds the second terminal as a forwarding target;

[0105] B16. The first terminal removes the second terminal as a forwarding target.

[0106] It should be noted that by clearly defining the specific actions taken by the first terminal to trigger the relationship notification, the first network function can be notified of changes in the specific devices connected to the first terminal.

[0107] For example, if the first triggering condition includes only any one of A21-A23, the first network function only knows that a device (or member) is connected to the first terminal. This situation is more suitable for AF to process requests from non-specific terminals sequentially. If the first triggering condition also includes any one of B11-B16, the first network function not only knows that a device (or member) is connected to the first terminal, but also knows which specific devices (or members) are connected to the first terminal.

[0108] Optionally, after the first network function sends a subscription request for the first event to the second network function based on the first information, the method further includes:

[0109] The first network function receives the relationship notification sent by the second network function;

[0110] In other words, when the second network function meets the first triggering condition, it sends a relationship notification to the first network function.

[0111] Specifically, the relationship notification is used to notify at least one of the following:

[0112] C11, The first terminal forwards data;

[0113] C12. The first terminal adds members;

[0114] C13. The first terminal adds a forwarding object;

[0115] C14. The first terminal forwards data from the second terminal;

[0116] C15. The first terminal stops forwarding data from the second terminal;

[0117] C16. The first terminal adds the second terminal as a member;

[0118] C17. The first terminal removes the second terminal as a member;

[0119] C18. The first terminal adds the second terminal as a forwarding object;

[0120] C19. The first terminal removes the second terminal as a forwarding target.

[0121] It should be noted that the first network function mentioned in the embodiments of this application refers to the Session Management Function (SMF). Specifically, the first network function can be understood as a network element or entity in the core network, or the first network function can be referred to as a first network function network element or a first network function entity. The second network function refers to the Network Open Function (NEF). The second network function can be understood as a network element entity in the core network, or the second network function can be referred to as a second network function network element or a second network function entity.

[0122] Optionally, step 201 in this embodiment is implemented as follows:

[0123] The first network function learns the first information from the second network function, the third network function, or the first terminal.

[0124] It should be noted that the third network function mentioned in the embodiments of this application refers to the unified data management (UDM) function or the unified data repository (UDR) function. Specifically, the third network function can be understood as a network element or entity in the core network, or it can be referred to as a third network function network element or a third network function entity.

[0125] That is to say, the first information can be sent from the first terminal to the SMF; it can also be sent from the NEF to the SMF; or the NEF can first send the first information to the UDM, and then the UDM can forward the first information to the SMF.

[0126] Specifically, if the first message is sent from NEF to UDM or SMF, NEF can send the first message in the following way:

[0127] NEF learns the information related to the first terminal and sends the first information to SMF or UDM based on the information related to the first terminal.

[0128] It should be noted that NEF can obtain information about the first terminal from UDM or from application functions (AF).

[0129] Optionally, the information related to the first terminal includes at least one of the following:

[0130] D11, Capability Information, used to indicate that the first terminal has gateway capabilities;

[0131] D12, Type information, used to indicate that the first terminal is a gateway device;

[0132] D13, Session Information, used to indicate that the session between the first terminal and the network is used for forwarding;

[0133] D14. Data network access information, used to indicate that the first terminal is used for data forwarding, the first terminal has gateway capabilities, the first terminal is a gateway device, or the session of the first terminal is used for forwarding.

[0134] In other words, once NEF learns about the first terminal's information, it can directly generate the first information based on that information and send it to the corresponding receiving end.

[0135] The following are examples illustrating the practical application of this application.

[0136] Specific Application Situation 1: NEF Actively Sends First Information

[0137] like Figure 3 As shown, the specific implementation process in this case is as follows:

[0138] Step 301: NEF obtains relevant information about the first terminal;

[0139] Optionally, NEF can obtain first terminal-related information from UDM or from AF.

[0140] Step 302: Send the first information to the UDM based on the relevant information of the first terminal;

[0141] Step 303: UDM forwards the first message to SMF;

[0142] Step 304: SMF sends a subscription request for relational events to NEF;

[0143] Step 305: The second terminal sends an access request to the first terminal;

[0144] Step 306: The first terminal sends a request to the AF requesting the second terminal to forward data through the 5G network;

[0145] Step 307: AF forwards the request from the first terminal to NEF;

[0146] Step 308: After receiving the request forwarded by the AF, the NEF sends a relationship notification to the SMF;

[0147] Specifically, the relationship notification is used to notify the first terminal to forward data.

[0148] Specific Application Scenario 2: SMF Requesting First Information

[0149] like Figure 4 As shown, the specific implementation process in this case is as follows:

[0150] Step 401: NEF obtains relevant information about the first terminal;

[0151] Step 402: NEF sends the first terminal-related information to UDM;

[0152] Step 403: SMF requests information related to the first terminal from UDM;

[0153] Step 404: UDM sends first information to SMF based on the first terminal information;

[0154] Step 405: SMF sends a subscription request for relational events to NEF;

[0155] Step 406: The second terminal sends an access request to the first terminal;

[0156] Step 407: The first terminal sends a request to the AF requesting the second terminal to forward data through the 5G network;

[0157] Step 408, AF forwards the request from the first terminal to NEF;

[0158] Step 409: After receiving the request forwarded by the AF, the NEF sends a relationship notification to the SMF;

[0159] Specifically, the relationship notification is used to notify the first terminal to add the second terminal as a member.

[0160] It should be noted that this application provides an implementation method for the SMF corresponding to the gateway session to independently initiate event subscription, so that the SMF connected to the gateway can clearly understand which devices are connected under the gateway, ensuring unified management of devices and ensuring data transmission reliability.

[0161] The information transmission method provided in this application can be executed by an information transmission device.
