Description

Technical Field

[0001] This application belongs to the field of communication technologies, and particularly relates to a method, apparatus, and network element for reporting or obtaining terminal capabilities. Background Art

[0002] Currently, the discussion on the network architecture of the 6th generation mobile networks (6G) involves the content of the data plane. Among them, the data plane consists of the core network data plane function, the radio access network data plane function, and the user equipment (UE) data plane function, and has end-to-end connectivity. The data plane is responsible for functions such as data control, data collection, data transmission, data preprocessing, data privacy and security, data analysis, data storage, and data services.

[0003] In recent technical discussions, the possibility of collecting data through the data plane has been involved. Currently, the core network (CN) side does not support obtaining information such as the coding methods and transmission paths supported by the UE, and there are many coding methods and transmission paths. Therefore, in the process of establishing a data plane connection between the UE and the CN, how the CN can obtain the coding methods and transmission paths supported by the terminal so that the CN data plane network element can obtain the corresponding data from the UE in a suitable and efficient manner is a technical problem that urgently needs to be solved.

[0226] To facilitate a clearer understanding of the technical solutions of the embodiments of this application, some technical content related to the embodiments of this application will be introduced first.

[0227] (1) Existing terminal capability reporting process.

[0228] The existing terminal capability reporting process is as Figure 2As shown, during the terminal registration process, the base station on the Radio Access Network (RAN) side will inform the Access and Mobility Management Function (AMF) of the terminal's Tracking Area (TA) and cell information. (That is, when the terminal registers, the AMF will know some location information of the terminal.) Other possible registration information also includes at least one of the following: Registration type; Subscription Concealed Identifier (SUCI) or 5th generation mobile networks (5G) - Globally Unique Temporary UE Identity (GUTI) or Permanent Equipment Identifier (PEI); Security parameters; additional GUTI; 4th generation mobile networks (4G) Tracking Area Update; the indication that the UE is moving from EPS; PLMN with Disaster Condition.

[0229] (2) Data plane and potential data plane protocol solutions.

[0230] In the current discussion of the 6G network architecture, multiple companies in the industry have proposed the data plane. The data plane consists of the core network data plane function, the radio access network data plane function, and the UE 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 transmission configuration, etc. The data plane is also responsible for functions such as data acquisition, data transmission, data preprocessing, data privacy and security, data analysis, data storage, and data services. The schematic diagram of the data plane is as Figure 3 shown.

[0231] Exemplarily, the data plane architecture diagram is as follows (the data plane connection between the terminal and the CN, the terminal is the data source):

[0232] The Data Plane-Control (DP-C) module and the Data Plane-User (DP-U) module are two modules related to the data plane within the terminal: The DP-C module is used to control the signaling related to the establishment, modification, and deletion of the data plane. The DP-U module is used to collect, process, and forward the relevant data within the terminal.

[0233] Correspondingly, the core network CN has corresponding network elements that correspond to the above two modules within the terminal:

[0234] The Data Plane Function-Control (DPF-C) network element is used to control the signaling related to the establishment, modification, and deletion of the data plane.

[0235] The Data Plane Function-User (DPF-U) network element is used to collect, process, and forward the relevant data from the terminal, the access network, or other data sources.

[0236] Among them, the signaling related to the terminal data plane (i.e., the signaling controlled by the DP-C module) can interact with the core network DPF-C based on different protocol stacks.

[0237] The existing Control Plane (CP) protocol stacks (such as the Non-Access Stratum (NAS) and the underlying Access Stratum (AS) protocol layers);

[0238] The newly added Data Plane (DP) protocol stacks, such as the Packet Data Convergence Protocol (PDCP), etc.

[0239] Similarly, the data forwarding of the terminal data plane (i.e., the data processed by the DP-U module) can interact with the core network DPF-U based on different protocol stacks.

[0240] The CP plane protocol stacks, such as the Non-Access Stratum (NAS) and the underlying Access Stratum (AS) protocol layers;

[0241] The UP plane protocol stacks, such as the Service Data Adaptation Protocol (SDAP), PDCP, etc.;

[0242] The DP plane protocol stacks, such as DsP1, PDCP, etc., where DsP1 is the data plane peer protocol layer between the UE and the RAN.

[0243] Data Plane DP Protocol Stack: A newly defined protocol stack exclusive to 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 segments, simple encapsulation format, etc., and streamlined encryption.

[0244] (3) Data Serialization Format Protocol.

[0245] The data description language Protocol Buffers (abbreviated as protobuf) is a data serialization format that can be used to serialize structured data into a transmittable binary format or deserialize the binary format into structured data. Compared with common data exchange formats such as the extensible markup language format XML and the lightweight data exchange format JSON, protobuf is more efficient and lightweight, so it has been widely used in applications with high concurrency and large amounts of data.

[0246] The characteristics of protobuf are as follows:

[0247] Small size: The serialized data has a very small volume and supports compressed transmission.

[0248] Fast speed: The speed of serialization and deserialization is very fast, much faster than traditional XML and JSON serialization methods.

[0249] Powerful functions: Supports multiple languages and has good scalability. It is easy to add, modify fields or change the message format.

[0250] Easy to read and maintain: When defining the data structure, it uses a semantic structure similar to object-oriented programming languages such as the computer programming language Java, which is easy to read, maintain and modify.

[0251] High security: The serialized data is generated through protobuf's Interactive Data Language (IDL), and it is not easy to have vulnerabilities and security risks.

[0252] There may be multiple data encoding methods for data transmission on the data plane connection between the UE and the CN, based on data serialization methods such as JSON, Protobuf, XML, etc., and each method has its own characteristics. For example:

[0253] JSON: A lightweight data exchange format, easy to read and write, supports multiple programming languages, and is commonly used in network Web applications. However, based on text, the data encoding and transmission efficiency is low.

[0254] XML: A markup language used to describe data, supports multiple programming languages, and is commonly used in Web applications and data exchange.

[0255] The data serialization format YAML: A human-readable data serialization format used for configuration files and data exchange, supporting multiple programming languages.

[0256] Protocol Buffers: An efficient binary serialization format that supports multiple programming languages and is commonly used in large-scale distributed systems.

[0257] The serialization format MessagePack: An efficient binary serialization format that supports multiple programming languages and is faster and smaller than JSON.

[0258] The computer data exchange format BSON: A binary JSON format that supports more data types and better performance and is commonly used in the database MongoDB for distributed file storage.

[0259] The encoding method ASN.1: It has the advantages of compact encoding, type safety, and good interoperability, but requires the use of specialized encoding and decoding tools and rules, and is more difficult to implement.

[0260] Next, in conjunction with the accompanying drawings, through some embodiments and their application scenarios, the terminal capability reporting method provided by the embodiments of the present application will be described in detail.

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

[0362] 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, thus enabling the second network element to flexibly obtain the data transmission capability information based on multiple methods.

[0363] 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, it further includes:

[0364] The third network element receives the 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.

[0365] Optionally, the third request information includes at least one of the following:

[0366] The first indication information; the first indication information is used to indicate that the second network element requests to obtain the data transmission capability information of the terminal;

[0367] The second indication information; the second indication information is used to indicate one or more items of the data transmission capability information that the second network element requests to obtain; 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 methods supported by each terminal, without the need to send other information such as the transmission path, thereby improving the efficiency of obtaining the data transmission capability information.

[0374] 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 acquisition efficiency of 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.

[0375] Figure 7 It is the third flowchart of the terminal capability acquisition method provided by the embodiments of the present application. The method includes:

[0376] Step 701, 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.

[0377] Specifically, the second network element can directly obtain the data transmission capability information from the terminal, or can 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 through various methods, thereby improving the flexibility of obtaining the data transmission capability information, meeting the requirements in different scenarios, and further improving the efficiency of the second network element in obtaining the corresponding data of the terminal.

[0378] 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, it further includes:

[0379] The second network element stores the data transmission capability information of the terminal.

[0380] 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, effectively improving the acquisition efficiency of the data storage capability information and the terminal-related data.

[0381] 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 can send a registration success message to the terminal through the first network element, for indicating that the second network element has successfully stored the data transmission capability information.

[0382] Optionally, the second network element receives the terminal's data transmission capability information from the terminal, the first network element, or the third network element, including:

[0383] 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 the terminal's data transmission capability information;

[0384] The second network element receives the terminal's data transmission capability information sent by the terminal, the first network element, or the third network element.

[0385] Specifically, when the second network element needs to obtain terminal-related data, it can also send 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 the terminal's data transmission capability information; among them, 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 information sent by the second network element, the terminal, the first network element, or the third network element can also send the required data transmission capability information to the second network element based on the third request information sent by the second network element, so that the second network element can also obtain the required data transmission capability information and perform the acquisition of terminal-related data.

[0386] For 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 realizing the acquisition of the terminal's data transmission capability information based on multiple methods.

[0387] Optionally, the third request information includes at least one of the following:

[0388] The first indication information; the first indication information is used to indicate that the second network element requests to obtain the terminal's data transmission capability information;

[0389] The second indication information; the second indication information is used to indicate one or more of the terminal's data transmission capability information to be requested by the second network element; for example, if the second indication information includes specific capability information, such as coding method information, then the terminal, the first network element, or the third network element only needs to send the coding methods supported by each terminal to the second network element, without the need to send other information such as the transmission path, thereby improving the acquisition efficiency of the data transmission capability information.

[0390] Service type information;

[0391] Service identification information;

[0392] Data type information;

[0393] Data identification information;

[0394] Terminal information;

[0395] Data service scope.

[0396] Optionally, after the second network element sends the third request message to the first network element or the third network element, the first network element or the third network element can, based on the third request message sent by the second network element, send the data transmission capability information required by the second network element to the second network element in a targeted manner, thereby improving the acquisition efficiency of the data transmission capability information.

[0397] 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, so as to establish a data plane connection with the terminal, and thus obtain the corresponding data from the terminal; after receiving the first request message sent by the second network element, the terminal can also, based on the first request message, establish a data plane connection with the second network element according to the first request message, and feedback the data required by the second network element to the second network element.

[0398] It should be noted that the above corresponding data is the data that satisfies the first request message, or the data collected by the terminal that satisfies the first request message. For example, the corresponding data is the data in the data collected by the terminal that matches the first request message. Specifically, the corresponding data is the data in the data collected by the terminal in which the service type information matches the first request message; taking this as an example, other information is similar and will not be elaborated here.

[0399] It should be noted that the above matching means including, or being the same, equal, etc.

[0400] Taking the first network element as the AMF, the second network element as the DPF, and the third network element as the 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 as Figure 8 shown, and this embodiment can be based on NAS to complete the interaction between the terminal and the core network.

[0401] 1. The terminal sends a first message to the AMF, and the first message includes the data transmission capability information of the terminal.

[0402] Optionally, through the registration process, the data transmission capability information of the terminal and the registration information can be sent to the AMF together. Among them, the first message can also be a request to register or update the data transmission capability information and / or willingness information of the terminal; among them, the data transmission capability information can also include the capability information related to data transmission, or the capability information related to data reporting and data collection; the willingness information is how the terminal prefers or only wishes to perform data transmission, and is a subset of the data transmission capability information.

[0403] Among them, the first message can be a registration request message.

[0404] 2. The AMF sends a storage request message to the UDM, and sends the data transmission capability information and / or willingness information in the first message sent by the terminal to the UDM, requesting the UDM to perform storage; optionally, it can be sent through the registration terminal context management Nudm_UECM_Registration service message.

[0405] In another implementation, it can also be the AMF itself that stores the data transmission capability information of the terminal.

[0406] 3 - 5. The UDM stores the data transmission capability information of the terminal and feeds back a storage success response message; the AMF feeds back a registration success message to the terminal.

[0407] 6. The DPF determines to obtain data from the terminal and / or determines the method of obtaining data from the terminal based on preset conditions or requests from other devices (such as when other devices request to obtain data of the terminal, etc.). A possible method is that before the DPF sends a request to obtain data to the terminal, the DPF first collects the data transmission capability information of the terminal and determines the data transmission method to be used according to the data transmission capability information of the terminal. For example, through which path to transmit control signaling, through which path to transmit data, how to perform encoding, etc.

[0408] 7a. The DPF sends a request to the AMF, requesting to obtain the data transmission capability information and / or willingness information of the terminal; specifically, the DPF may also be a service - based network element and can directly interact with the AMF through the core network bus; or the DPF may have interfaces with network elements such as the AMF for connection, communication, and interaction.

[0409] 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. Among them, 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 to obtain the data transmission capability information of the terminal.

[0410] 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. Among them, the target terminal can be determined by at least one piece of information such as 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.

[0411] 7a–8a and 7b-8b are two optional ways. The difference is that in 7a-8a, the DPF and the AMF interact to obtain the UE's data transmission capability information, and in 7b-8b, the DPF and the UDM interact to obtain the UE's data transmission capability information. This will not be elaborated in the embodiments of this application.

[0412] 9. The DPF determines a method for data collection and sends a request message for data collection to the target terminal to collect data from the target terminal.

[0413] Specifically, the DPF determines the request message based on the terminal's data transmission capability information and / or the received data request, etc. 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 to perform data collection, what coding method to use for coding, and which path to use to feedback the data based on the first path, second path, coding method, etc. supported by the terminal and / or the first path, second path, coding method, etc. of the willingness (preferred).

[0414] Exemplarily, another embodiment of the second network element DPF obtaining the terminal's data transmission capability information is as Figure 9 shown. This embodiment can be based on NAS or a new message.

[0415] 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 relevant data of the terminal, it can directly utilize 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, and the efficiency is also higher. 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.

[0416] In the above embodiments, the terminal reports information such as the coding method it supports, the data transmission paths it supports, and the data plane capabilities to the core network. Network elements responsible for data collection such as the 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, so as to quickly and accurately determine the target UE and collect the target data.
