[0228] In order to facilitate a clearer understanding of the technical solutions of the various embodiments of the present application, some technical contents related to the various embodiments of the present application are first introduced.

[0229] (1) Existing terminal capability reporting process.

[0230] Figure 2 shows the existing terminal capability reporting process. During terminal registration, the base station on the Radio Access Network (RAN) side informs the AMF of the terminal's Tracking Area (TA) and cell information. (That is, the AMF will know some of the terminal's location information during terminal registration.) Other possible registration information may include at least one of the following: Registration type; Subscription concealed identifier (SUCI) or Globally Unique Temporary UE Identity (GUTI) or Permanent Equipment Identifier (PEI) for 5th generation mobile networks (5G); Security parameters; Additional GUTI; Tracking Area Update for 4th generation mobile networks (4G); Indication that the UE is moving from EPS; and PLMN with Disaster Condition.

[0231] (2) Data plane and potential data plane protocol solutions.

[0232] In current discussions about 6G network architecture, many industry companies have proposed the data plane. The data plane comprises core network data plane functions, radio access network data plane functions, and UE 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 and security, data analysis, data storage, and data services. A schematic diagram of the data plane is shown in Figure 3.

[0233] For example, the data plane architecture diagram is as follows (data plane connection between terminal and CN, terminal is the data source):

[0234] The Data Plane-Control (DP-C) and Data Plane-User (DP-U) modules are the two data plane modules within the terminal. The DP-C controls signaling related to establishing, modifying, and deleting the data plane. The DP-U collects, processes, and forwards data within the terminal.

[0235] Correspondingly, the core network CN has corresponding network elements corresponding to the above two modules in the terminal:

[0236] The Data Plane Function-Control (DPF-C) is used to control the establishment, modification, and deletion of data plane related signaling.

[0237] The Data Plane Function-User (DPF-U) is used to collect, process, and forward relevant data from terminals, access networks, or other data sources.

[0238] Among them, the terminal data plane related signaling (i.e., the signaling controlled by the data plane control module DP-C) can interact with the core network data plane control network element DPF-C based on different protocol stacks.

[0239] Existing control plane (CP) protocol stack (such as the non-access layer NAS and the underlying access layer AS protocol layer);

[0240] Newly added data plane (DP) protocol stack, such as Packet Data Convergence Protocol (PDCP).

[0241] Similarly, data forwarding on the terminal data plane (i.e., data processed by the data plane forwarding module DP-U) can interact with the core network DPF-U based on different protocol stacks.

[0242] CP plane protocol stack, such as the Non-Access Stratum (NAS) and underlying Access Stratum (AS) protocol layers;

[0243] UP plane protocol stack, such as Service Data Adaptation Protocol (SDAP), PDCP, etc.

[0244] DP plane protocol stack, such as DsP1, PDCP, etc., where DsP1 is the data plane peer protocol layer between UE and RAN.

[0245] Data plane DP protocol stack: A newly defined protocol stack exclusively for the data plane, which conforms to the new characteristics of data transmission on the data plane, such as massive data transmission, large bandwidth, large data segmentation, simple encapsulation format, and streamlined encryption.

[0246] (3) Data serialization format Protocol.

[0247] The data description language Protocol Buffers (protobuf) is a data serialization format that can be used to serialize structured data into a transmittable binary format, or deserialize binary data into structured data. Compared to common data exchange formats such as XML and the lightweight JSON data exchange format, protobuf is more efficient and lightweight, making it widely used in high-concurrency, large-scale applications.

[0248] The characteristics of protobuf are as follows:

[0249] Small size: The serialized data is very small and supports compressed transmission.

[0250] Fast: Serialization and deserialization are very fast, much faster than traditional XML and JSON serialization methods.

[0251] Powerful: It supports multiple languages ​​and is highly extensible, making it easy to add or modify fields or change message formats.

[0252] Easy to read and maintain: When defining data structures, semantic structures similar to object-oriented programming languages ​​such as Java are used, which are easy to read, maintain, and modify.

[0253] High security: Serialized data is generated through protobuf's Interactive Data Language (IDL), which is less prone to vulnerabilities and security risks.

[0254] There may be multiple data encoding methods for data transmission on the data plane connection between UE and CN, based on data serialization methods such as JSON, Protobuf, and XML, and each method has its own characteristics. For example:

[0255] JSON: A lightweight data exchange format that is easy to read and write, supports multiple programming languages, and is commonly used in web applications. However, it is text-based and has low data encoding and transmission efficiency.

[0256] XML: A markup language used to describe data that supports multiple programming languages ​​and is commonly used in web applications and data exchange.

[0257] Data serialization format YAML: A human-readable data serialization format used for configuration files and data exchange, supporting multiple programming languages.

[0258] Protocol Buffers: An efficient binary serialization format that supports multiple programming languages ​​and is commonly used in large-scale distributed systems.

[0259] Serialization format MessagePack: An efficient binary serialization format that supports multiple programming languages ​​and is faster and smaller than JSON.

[0260] BSON (Computer Data Interchange Format): A binary JSON format that supports more data types and better performance. It is commonly used in the distributed file storage database MongoDB.

[0261] Encoding method ASN.1: It has the advantages of compact coding, type safety, and good interoperability, but it requires the use of special encoding and decoding tools and rules, making it difficult to implement.

[0262] The terminal capability reporting method provided in the embodiment of the present application is described in detail below with reference to some embodiments and their application scenarios in conjunction with the accompanying drawings.

Optionally, if the first network element or the second network element does not receive the response information sent by the third network element, the first network element or the second network element may repeatedly send the data transmission capability information to the third network element, so that the third network element can store the data transmission capability information in a timely manner.

[0364] Optionally, the third network element can directly send the data transmission capability information of the terminal to the second network element; the third network element can also send the data transmission capability information of the terminal to the first network element, and then the first network element provides the data transmission capability to the second network element, so that the second network element can flexibly obtain the data transmission capability information based on multiple methods.

[0365] Optionally, before the third network element sends the data transmission capability information of the terminal to the first network element or the second network element, the method further includes:

[0366] The third network element receives third request information sent by the first network element or the second network element; the third request information is used to request to obtain the data transmission capability information of the terminal.

[0367] Optionally, the third request information includes at least one of the following:

[0368] First indication information; the first indication information is used to instruct the second network element to request to obtain the data transmission capability information of the terminal;

[0369] Second indication information; the second indication information is used to instruct the second network element to request one or more items of the terminal's data transmission capability information; for example, when the second network element only needs to obtain the encoding method supported by the terminal, it can only request the third network element to send the encoding method supported by each terminal without sending other information such as the transmission path, thereby improving the efficiency of obtaining the data transmission capability information.

[0370] Business type information;

[0371] Business identification information;

[0372] Data type information;

[0373] Data identification information;

[0374] Terminal information;

[0375] Data service scope.

[0376] That is, based on the third request information sent by the second network element, the third network element can specifically send the data transmission capability information required by the second network element to the second network element, thereby improving the efficiency of obtaining the data transmission capability information. Optionally, if the third network element does not store the data transmission capability information of the terminal, after receiving the third request information sent by the second network element, the third network element can also obtain the data transmission capability information of the terminal from the first network element, and then send the data transmission capability information of the terminal to the second network element.

[0377] FIG7 is a third flow chart of a method for acquiring terminal capabilities according to an embodiment of the present application, the method comprising:

[0378] Step 701: The second network element receives data transmission capability information of the terminal from the terminal, the first network element or the third network element.

[0379] Specifically, the second network element can obtain data transmission capability information directly from the terminal, or obtain the data transmission capability information of the terminal through the first network element or the third network element, so that the second network element can obtain the required data transmission capability information in a variety of ways, thereby improving the flexibility of obtaining data transmission capability information, meeting the needs of different scenarios, and further improving the efficiency of the second network element in obtaining the corresponding data of the terminal.

[0380] Optionally, after the second network element receives the data transmission capability information of the terminal from the terminal, the first network element, or the third network element, the further step includes:

[0381] The second network element stores the data transmission capability information of the terminal.

[0382] Specifically, the second network element can receive and store the data transmission capability information sent by the first network element. Then, when the second network element needs to obtain terminal-related data, it can obtain the terminal-related data in a reasonable and efficient manner based on the data transmission capability information stored by itself, thereby effectively improving the efficiency of obtaining data storage capability information and terminal-related data.

[0383] Optionally, after the second network element receives and stores the data transmission capability information of the terminal sent by the first network element, the second network element may send registration success information to the terminal through the first network element, indicating that the second network element has successfully stored the data transmission capability information.

[0384] Optionally, the second network element receives the data transmission capability information of the terminal from the terminal, the first network element, or the third network element, including:

[0385] The second network element sends third request information to the terminal, the first network element or the third network element; the third request information is used to request to obtain data transmission capability information of the terminal;

[0386] The second network element receives the data transmission capability information of the terminal sent by the terminal, the first network element or the third network element.

[0387] Specifically, when the second network element needs to acquire terminal-related data, it may also send a third request message to the terminal, the first network element, or the third network element; the third request message is used to request acquisition of the terminal's data transmission capability information; wherein the first network element and the third network element are network elements that have stored data transmission capability information. After the terminal, the first network element, or the third network element receives the third request message sent by the second network element, the terminal, the first network element, or the third network element may also send the required data transmission capability information to the second network element based on the third request message sent by the second network element, so that the second network element can also acquire the required data transmission capability information and acquire terminal-related data.

[0388] In the method of the above embodiment, when the second network element needs to obtain terminal-related data, it can obtain the required data transmission capability information from the terminal, the first network element or the third network element, thereby achieving the acquisition of the terminal's data transmission capability information based on multiple methods.

[0389] Optionally, the third request information includes at least one of the following:

[0390] First indication information; the first indication information is used to instruct the second network element to request to obtain the data transmission capability information of the terminal;

[0391] Second indication information; the second indication information is used to instruct the second network element to request to obtain one or more items of the terminal's data transmission capability information; for example, the second indication information includes specific capability information, such as encoding method information, then the terminal, the first network element or the third network element only needs to send the encoding method supported by each terminal to the second network element, without sending other information such as the transmission path, thereby improving the efficiency of obtaining data transmission capability information.

[0392] Business type information;

[0393] Business identification information;

[0394] Data type information;

[0395] Data identification information;

[0396] Terminal information;

[0397] Data service scope.

[0398] Optionally, after the second network element sends the third request information to the first network element or the third network element, the first network element or the third network element can send the data transmission capability information required by the second network element to the second network element based on the third request information sent by the second network element, thereby improving the efficiency of obtaining the data transmission capability information.

[0399] Optionally, when the second network element needs to obtain relevant data of the terminal, it can determine and send a first request message to the terminal; the first request message is used to request to obtain the data corresponding to the terminal, thereby establishing a data plane connection with the terminal, and thus obtaining the corresponding data from the terminal; after receiving the first request message sent by the second network element, the terminal can also establish a data plane connection with the second network element based on the first request message, and feedback the data required by the second network element to the second network element.

[0400] It should be noted that the corresponding data described above refers to data that satisfies the first request information, or data collected by the terminal that satisfies the first request information. For example, the corresponding data refers to data in the data collected by the terminal that matches the first request information. Specifically, the corresponding data refers to data in the data collected by the terminal that matches the service type information in the first request information. This example is used as an example, and other information is similar and will not be further described here.

[0401] It should be noted that the above-mentioned matching refers to including, or being the same, being equal and the like.

[0402] Taking the first network element as AMF, the second network element as DPF, and the third network element as UDM as an example, when the second network element DPF obtains the data transmission capability information of the terminal, the interaction process with the first network element AMF, the third network element UDM and the terminal is shown in Figure 8. This embodiment can be based on NAS to complete the interaction between the terminal and the core network.

[0403] 1. The terminal sends a first message to the AMF, where the first message includes the data transmission capability information of the terminal.

[0404] Optionally, the terminal's data transmission capability information and registration information can be sent to the AMF together through the registration process. The first message can also be a request to register or update the terminal's data transmission capability information and / or willingness information. The data transmission capability information can also include capability information related to data transmission, or capability information related to data reporting and data collection. The willingness information indicates which methods the terminal prefers or is only willing to use for data transmission and is a subset of the data transmission capability information.

[0405] The first message may be a registration request message.

[0406] 2. AMF sends a storage request message to UDM, sends the data transmission capability information and / or willingness information in the first message sent by the terminal to UDM, and requests UDM to store it; optionally, it can be sent through the registration terminal context management Nudm_UECM_Registration service message.

[0407] In another implementation, the AMF itself may store the data transmission capability information of the terminal.

[0408] 3-5. The UDM stores the terminal's data transmission capability information and returns a successful storage response message; the AMF returns a successful registration message to the terminal.

[0409] 6. The DPF determines to obtain data from the terminal and / or determines a method for obtaining data from the terminal based on preset conditions or requests from other devices (e.g., requests from other devices to obtain data from the terminal). One possible method is that before the DPF sends a request to obtain data to the terminal, the DPF first collects the terminal's data transmission capability information and determines the data transmission method to be used based on the terminal's data transmission capability information, for example, the path for transmitting control signaling, the path for transmitting data, the encoding method, etc.

[0410] 7a. DPF sends a request to AMF to obtain the terminal's data transmission capability information and / or willingness information; specifically, DPF may also be a service-oriented network element that can interact directly with AMF through the core network bus; or DPF may have an interface with network elements such as AMF for connection, communication, and interaction.

[0411] 8a. The AMF sends the data transmission capability information of the terminal that meets the conditions to the DPF. Specifically, after receiving the request message from the DPF, the AMF sends the data transmission capability information that meets the conditions to the DPF. The data transmission capability information can be based on the data transmission capability information stored by the AMF itself and / or the AMF sends a request to the UDM to request the data transmission capability information of the terminal.

[0412] Specifically, the AMF determines the target terminal based on the request message sent by the DPF and sends the data transmission capability information of the target terminal to the DPF. The target terminal can be determined by at least one of the service type or identifier, the type or identifier of the data to be obtained, the data object, and the data range in step 7a.

[0413] 7a–8a and 7b-8b are two optional methods. The difference is that 7a-8a is the interaction between DPF and AMF to obtain the data transmission capability information of the UE, and 7b-8b is the interaction between DPF and UDM to obtain the data transmission capability information of the UE. They will not be repeated in the embodiment of this application.

[0414] 9. The DPF determines the data collection method and sends a data collection request message to the target terminal to collect data from the target terminal.

[0415] Specifically, the DPF determines a request message based on the terminal's data transmission capability information and / or a received data request, and the request message is used to request the establishment of a data plane connection with the terminal to obtain relevant data of the terminal. For example, after the DPF receives the terminal's data transmission capability information and / or willingness information, the DPF determines which path to use to inform the terminal for data collection, which encoding method to use for encoding, and which path to use to feedback data based on the terminal's supported first path, second path, encoding method, etc. and / or the preferred (preferred) first path, second path, encoding method, etc.

[0416] Illustratively, another embodiment in which the second network element DPF obtains the data transmission capability information of the terminal is shown in FIG9 . This embodiment may be based on NAS or a new message.

[0417] In this embodiment, the terminal directly sends its data transmission capability information and / or willingness information to the DPF through the AMF. When the DPF needs to obtain terminal-related data, it can directly use the data transmission capability information stored in itself without sending a request message to the AMF or UDM network element to obtain the data transmission capability information, which is more efficient. It should be noted that the DPF may also be DPF-C or DPF-U; DPF-C and DPF-U can also store terminal registration data.

[0418] In the above embodiment, the terminal reports information such as the supported encoding methods, supported data transmission paths and data plane capabilities to the core network. The network elements responsible for data collection, such as DPF, determine whether and how to send a data acquisition request to the terminal based on the data transmission capability information reported by the terminal, thereby quickly and accurately determining the target UE and collecting the target data.
