[0048] For ease of understanding, the relevant technologies and concepts involved in the embodiments of this application are introduced first.

[0049] I. Data plane and potential data plane protocol solutions

[0050] The data plane was mentioned in the discussion of the 6G network architecture. AsFigure 2 As shown, the data plane consists of the core network data plane function, the radio access network data plane function, and the terminal data plane function, and has end-to-end connectivity. The data plane is responsible for data control, including data collection coordination, data collection configuration, and data transfer configuration, etc. The data plane is also responsible for functions such as data acquisition, data transfer, data preprocessing, data privacy processing, data analysis, data storage, and data services.

[0051] II. 5G Network Data Analysis Service

[0052] NWDAF is one of the network functions of the 5G core network control plane (5GC), and interacts with different entities for different purposes:

[0053] 1) Collect data based on event subscriptions provided by AMF, SMF, PCF, UDM, AF (directly or through NEF), or Operation, Administration and Maintenance (OAM);

[0054] 2) Use the Data Collection Coordination Function (DCCF) for analysis and data collection (optional);

[0055] 3) Retrieve information from the data repository, such as the UDR that retrieves user-related information through the UDM;

[0056] 4) Store and retrieve information from the Analytics Data Repository Function (ADRF) (optional);

[0057] 5) Analyze and collect data from the Messaging Framework Adaptor Function (MFAF);

[0058] 6) Retrieve information about the Network Function Service (NFS), such as retrieving NFS-related information from the NRF;

[0059] 7) Provide analysis results to consumer network elements according to requirements;

[0060] 8) Provide data to consumer network elements.

[0061] Such as Figure 3As shown in the figure, the NWDAF can collect data of other NFs through the DCCF. Specifically, the NWDAF requests the DCCF to collect data of certain network elements through the Ndccf interface. For example, the DCCF collects data from the target NF through the Nnf interface. Before collecting data from the target NF, the target NF is determined by network elements such as the NRF, UDM, or BSF. After the collection is completed, the data can be directly fed back to the NWDAF or indirectly fed back through the MFAF. The interface between the DCCF and the MFAF, as well as the interface between the MFAF and the NWDAF, is the Nmfaf.

[0062] As Figure 4 As shown in the figure, the target NF can collect data from the NWDAF through the DCCF. Specifically, the target NF requests data analysis through the Ndccf interface. For example, the DCCF sends a data acquisition request to the NWDAF through the Nnwdaf interface. Before sending a data acquisition request to the NWDAF, the NWDAF is determined by network elements such as the NRF, UDM, or BSF. The NWDAF feeds back the analyzed data to the NF or indirectly feeds back the analyzed data through the MFAF. The interface between the DCCF and the MFAF, as well as the interface between the MFAF and the NF, is the Nmfaf.

[0063] The related technologies and concepts involved in the embodiments of the present application are introduced above. Next, in combination with the accompanying drawings, the communication method provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0064] See Figure 5 As shown in the figure, it is a flowchart of the implementation of a communication method provided by the embodiments of the present application. The method includes the following steps:

[0065] S510: The first communication device sends a first message to the second communication device. The first message includes the data plane-related capability information corresponding to the first communication device.

[0066] Applying the method provided by the embodiments of the present application, the first communication device sends a first message to the second communication device. The first message includes the data plane-related capability information corresponding to the first communication device, so that the second communication device can clearly know the data plane-related capabilities of the first communication device, and can accurately find a communication device that meets the conditions when it is necessary to find a communication device with data plane-related capabilities.

[0067] 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 with data-plane functions, such as a Data Plane Function (DPF), a DPF-Control, a DPF-User, etc. The second communication device may be a network element with storage functions, such as an NRF. Among them, the data plane function may also be referred to as a data plane network element. The DPF-C can be used to control signaling related to data plane establishment, modification, deletion, etc. The DPF-U can also be referred to as a data plane forwarding network element and can be used to collect, process, and forward relevant data from terminals, RANs, or other data sources.

[0068] The first communication device has certain data-plane related capability information. The first communication device may send a first message to the second communication device, and the first message may include the data-plane related capability information corresponding to the first communication device. After receiving the first message, the second communication device may store the data-plane related capability information corresponding to the first communication device according to the first message, and then send a first response message to the first communication device. The first response message is used to indicate the result of the second communication device storing the data-plane related capability information corresponding to the first communication device. After receiving the first response message from the second communication device, the first communication device can learn the corresponding storage result, such as successful storage or failed storage.

[0069] It should be noted that if the second communication device has previously stored the data-plane related capability information corresponding to the first communication device, the first message can also be understood as a message for updating the data-plane related capability information corresponding to the first communication device.

[0070] It should be noted that the data plane may refer to a plane for large-scale data transmission and may have the following characteristics: it can perform massive data transmission, has a large bandwidth, large data segments, a simple data encapsulation format, and simple encryption.

Among them, the ability to establish a data plane or modify a data plane can be understood as the first communication device can decide whether to establish or modify a data plane, and how to establish or modify a data plane. For example, after the first communication device receives information such as the Internet Protocol (IP) address or port number of the terminal, it determines whether a data plane can be established or modified, and whether the first communication device or other communication devices establish or modify the data plane with the terminal. When the first communication device is a DPF-C, the other communication device can be a DPF-U.
