[0050] To facilitate understanding, the relevant technologies and concepts involved in the embodiments of this application are first introduced.

[0051] 1. Data Plane and Potential Data Plane Protocol Solutions

[0052] The data plane has been mentioned in discussions of 6G network architecture. As shown in Figure 2, the data plane comprises core network data plane functions, radio access network data plane functions, and terminal data plane functions, providing end-to-end connectivity. The data plane is responsible for data control, including data collection coordination, data collection configuration, and data transmission configuration. It also handles data acquisition, data transmission, data preprocessing, data privacy protection, data analysis, data storage, and data services.

[0053] 2. 5G Network Data Analysis Service

[0054] NWDAF is a network function of the 5G core control plane (5GC). It interacts with different entities to achieve different purposes:

[0055] 1) Collect data based on event subscriptions provided by AMF, SMF, PCF, UDM, AF (directly or through NEF) or Operation, Administration and Maintenance (OAM);

[0056] 2) Use the Data Collection Coordination Function (DCCF) for analysis and data collection (optional);

[0057] 3) Retrieve information from the data repository, such as a UDR that retrieves user-related information through the UDM;

[0058] 4) Store and retrieve information from the Analytics Data Repository Function (ADRF) (optional);

[0059] 5) Analysis and data collection from the Messaging Framework Adaptor Function (MFAF);

[0060] 6) Retrieve information about the Network Function Service (NFS), such as retrieving NFS-related information from the NRF;

[0061] 7) Provide analysis results to consumer network elements based on demand;

[0062] 8) Provide data to consumer network elements.

[0063] As shown in Figure 3, the NWDAF can collect data from other NFs through the DCCF. Specifically, the NWDAF requests the DCCF to collect certain network element data through the Ndccf interface. For example, the DCCF collects data from the target NF through the Nnf interface. Before data collection from the target NF, the target NF is first determined through network elements such as the NRF, UDM, or BSF. After collection is complete, the data can be fed back to the NWDAF directly or indirectly through the MFAF. The interface between the DCCF and MFAF, and between the MFAF and NWDAF, is called Nmfaf.

[0064] As shown in Figure 4, the target NF can collect data from the NWDAF via the DCCF. Specifically, the target NF requests analysis data through the Ndccf interface. For example, the DCCF sends a data acquisition request to the NWDAF via the Nnwdaf interface. Before sending the data acquisition request to the NWDAF, the NWDAF is first identified through network elements such as the NRF, UDM, or BSF. The NWDAF then feeds the analysis data back to the NF, or indirectly through the MFAF. The interface between the DCCF and MFAF, and between the MFAF and the NF, is Nmfaf.

[0065] The above introduces the relevant technologies and concepts involved in the embodiments of the present application. Now, in combination with the accompanying drawings, the communication method provided in the embodiments of the present application is described in detail through some embodiments and their application scenarios.

[0068] By applying the method provided in the embodiment of the present application, a first communication device sends a first message to a second communication device, where the first message includes data plane-related capability information corresponding to the first communication device. This enables the second communication device to clearly understand the data plane-related capabilities corresponding to the first communication device, so that when it is necessary to search for a communication device with data plane-related capabilities, it can accurately find a communication device that meets the conditions.

[0069] In an embodiment of the present application, the first communication device may be a data plane related network element or a network element or device having a data plane function, such as a data plane function (DPF), a data plane control network element (DPF-Control, DPF-C), a data plane user network element (DPF-User, DPF-U), etc., and the second communication device may be a network element having a storage function, such as an NRF.

The first response message indicates the result of the second communication device storing the data plane capability information corresponding to the first communication device. After receiving the first response message from the second communication device, the first communication device may obtain the corresponding storage result, such as whether the storage was successful or failed.

[0071] It should be noted that if the second communication device previously stores the data plane capability information corresponding to the first communication device, the first message can also be understood as a message for updating the data plane capability information corresponding to the first communication device.

For example, after receiving information such as the Internet Protocol (IP) address or port number of the terminal, the first communication device determines whether the data plane can be established or modified, and whether the data plane is established or modified by the first communication device or other communication devices with the terminal. In the case where the first communication device is a DPF-C, the other communication devices may be DPF-U.
