[0041] FIG1 is a block diagram of a wireless communication system applicable to an embodiment of the present application. The wireless communication system includes a terminal 11 and a network-side device 12. The terminal 11 may be a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (Laptop Computer), a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device (Wearable Device), an aircraft (Flight Vehicle), a vehicle-mounted device (VUE), a ship-mounted device, a pedestrian user equipment (PUE), a smart home (home appliances with wireless communication capabilities, such as refrigerators, televisions, washing machines, or furniture), a game console, a personal computer (PC), an ATM, or a self-service machine, or other terminal-side devices. Wearable devices include: smart watches, smart bracelets, smart headphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart anklets, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle-mounted device can also be called a vehicle-mounted terminal, a vehicle-mounted controller, a vehicle-mounted module, a vehicle-mounted component, a vehicle-mounted chip or a vehicle-mounted unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application. The network side device 12 may include an access network device or a core network device, wherein the access network device may also be called a radio access network (Radio Access Network, RAN) device, a radio access network function or a radio access network unit. The access network device may include a base station, a wireless local area network (WLAN) access point (AP) or a wireless fidelity (WiFi) node, etc.Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), Home Node B (HNB), Home Evolved Node B (home evolved Node B), Transmission Reception Point (TRP) or other appropriate terms in the field.

It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0042] The core network equipment may include but is not limited to at least one of the following: core network node, core network function, mobility management entity (MME), access mobility management function (AMF), session management function (SMF), user plane function (UPF), policy control function (PCF), policy and charging rules function unit (PCRF), edge application service discovery function (EASDF), unified data management (UDM), unified data repository (UDR), home user server (HSS), centralized network configuration (CNC), network storage function (NRF), network exposure function (NEF), local NEF (L-NEF), binding support function (BSF), application function ( It should be noted that in the embodiments of the present application, only the core network device in the NR system is introduced as an example, and the specific type of the core network device is not limited.

[0043] First, the technical terms and application scenarios involved in the embodiments of this application are introduced:

[0044] When a network device needs to establish a data plane connection with a terminal to obtain data from the terminal, multiple potential paths may exist. For example, the data plane connection can be based on a user plane path (user plane protocol stack), a control plane path (control plane protocol stack), or optionally, a newly defined data plane path (data plane protocol stack). However, it is currently unclear how the terminal and network device determine and negotiate the selection of a path to carry the data plane connection.

[0045] Data transmission on the data plane connection between the terminal and the network-side device may use a variety of data encoding methods, including JavaScript Object Notation (JSON), Abstract Syntax Notation One (ASN.1), Protocol Buffer (Protobuf), Extensible Markup Language (XML), Yet Another Markup Language (YAML), MessagePack, and Binary JSON (BSON). Each method has its own characteristics, as follows:

[0046] JSON: A lightweight data exchange format that's easy to read and write, supports multiple programming languages, and is commonly used in web applications. However, JSON is text-based, resulting in low data encoding and transmission efficiency.

[0047] ASN.1: It has the advantages of compact coding, type safety, and good interoperability, but it requires the use of specialized encoding and decoding tools and rules, making it difficult to implement.

[0048] Protocol Buffer: An efficient binary serialization format that supports multiple programming languages ​​and is commonly used in large-scale distributed systems.

[0049] XML: A markup language used to describe data that supports multiple programming languages ​​and is commonly used in web applications and data exchange.

[0050] YAML: A human-readable data serialization format for configuration files and data exchange, supporting multiple programming languages.

[0051] MessagePack: An efficient binary serialization format that supports multiple programming languages ​​and is faster and smaller than JSON.

[0052] BSON: A binary JSON format that supports more data types and better performance, commonly used in MongoDB databases.

[0053] However, it is not clear how the terminal and network-side devices select and negotiate data encoding methods based on different requirements.

[0054] Figure 2 shows the data plane architecture, the data plane (DP) connection between the terminal and the network side equipment, for example, the terminal is the data source;

[0055] DP-C and DP-U are two modules related to the data plane inside the terminal:

[0056] 1. DP-C is the data plane control module, which is used to control the establishment, modification and deletion of data plane related signaling.

[0057] 2. DP-U is the data plane forwarding module, which is used to collect, process and forward relevant data in the terminal.

[0058] Correspondingly, the core network side has corresponding network elements (such as the Data Plane Function (DPF)) corresponding to the above two modules in the terminal:

[0059] 1. DPF-C is the data plane control network element, which is used to control the establishment, modification and deletion of related signaling of the data plane.

[0060] 2. DPF-U is a data plane forwarding network element used to collect, process and forward relevant data from terminals, RAN or other data sources.

[0061] It should be noted that the network elements on the above-mentioned core network side can be other network element names, or be replaced by network elements with other similar functions, such as the Data Collection Coordination Function (DCCF) network element, or the Messaging Framework Adaptor Function (MFAF) network element.

[0062] Among them, the terminal's data plane related signaling (i.e., signaling controlled by the DP-C module) can interact with the core network side DPF-C based on different protocol stacks. For example, as shown in line 2 in Figure 2:

[0063] 1. Based on the existing CP plane protocol stack (such as the non-access stratum (NAS) and the underlying access layer AS protocol layer);

[0064] 2. Based on the newly added DP protocol stack (such as Data Stratum Protocol 1 (DsP1) and Packet Data Convergence Protocol (PDCP), where DsP1 is the data interface peer-to-peer protocol layer between the terminal and the RAN);

[0065] It should be noted that the DP plane protocol stack between the terminal and the network side may pass through (over) or not pass through the DsP1 protocol layer.

[0066] When passing through the DsP1 layer, the RAN can parse the DsP1 protocol layer, and can obtain and parse part or all of the information in the data transmitted by the terminal to the core network side, which is conducive to the data plane module in the RAN to obtain relevant information.

[0067] If the data does not pass through DsP1, RAN transparently transmits the data transmitted by the terminal to the core network side.

[0068] Similarly, the data forwarding of the terminal's data plane (i.e., data processed by the DP-U module) can interact with the core network DPF-U based on different protocol stacks. For example, as shown in line 1 in Figure 2:

[0069] 1. Based on the CP-side protocol stack (such as NAS and the underlying AS protocol layer);

[0070] 2. Based on the UP plane protocol stack (such as Service Data Adaptation Protocol (SDAP), PDCP, etc.)

[0071] 3. Based on the DP plane protocol stack (such as DsP1, PDCP, etc., where DsP1 is the data plane peer protocol layer between the terminal and RAN)

[0072] Among them, the DP plane protocol stack is 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.

[0073] Optionally, DsP1-C and DsP1-U in FIG2 may be absent;

[0074] Optionally, DsP1-C and DsP1-U can be combined into one;

[0075] Optionally, the DP-U and DP-C paths may be combined into one.

[0076] Alternatively, FIG2 takes the separation of DP-C and DP-U, and the separation of DPF-C and DPF-U as an example, but in fact DP-C and DP-U can be combined, and DPF-C and DPF-U can also be combined.

[0077] Optionally, in the embodiment of the present application, the data source (Data source) includes at least one of the following: terminal, RAN, core network function (Core Network Network Function, CN NF), operation and maintenance management (OAM), data storage network element (such as analytical data storage function (ADRF)), application layer function (AF), etc. The modules that generate data in the terminal include but are not limited to business data modules and basic public data modules such as sensing, artificial intelligence (AI), and positioning. The data source in RAN can include access network data plane equipment. The data source in CN includes but is not limited to sensing function, data storage function (data storage, such as ADRF), AI-related equipment (such as network data analysis function (NWDAF)), etc. The data source of AF includes but is not limited to trusted AF, untrusted AF, etc. Among them, the data source includes data sources connected to the service-oriented architecture (such as CN NF, OAM, etc.) and sources that are not connected to the service-oriented architecture (such as terminals, RAN, etc.).

[0078] Data consumers include at least one of the following: terminal, RAN, CN NF, OAM, ADRF, AF, etc. Data consumers include consumers connected to the service-based architecture (such as CN NF, OAM, etc.) and consumers not connected to the service-based architecture (such as terminal, RAN, etc.).

[0079] Optionally, the architecture of the embodiment of the present application may not fully realize network service, that is, some devices or network elements (such as terminals, RAN, certain AFs, etc.) are not service-oriented, and they still communicate with other devices in the network (including service-based architecture (SBA) network element devices) through point-to-point interfaces.

[0080] For example, when the terminal serves as the data source, how to agree on the signaling and data transmission path and processing method during the process of establishing a data plane connection between the terminal, access network equipment and core network CN so that the CN data plane network elements can obtain the corresponding data from the terminal in an appropriate and efficient manner is a problem that needs to be solved.

[0081] The following describes in detail the method for establishing a data plane connection provided by the embodiment of the present application through some embodiments and their application scenarios in conjunction with the accompanying drawings.

[0082] Referring to FIG. 3 , an embodiment of the present application provides a method for establishing a data plane connection. The embodiment is performed by a first device. The method includes:

[0083] Step 101: A first device receives a first request message from a second device.

[0084] Step 102: The first device establishes a data plane connection with the target device based on the first request message.

[0086] Optionally, the second device includes at least one of an access network device and a core network device.

[0087] Optionally, the target device includes at least one of an access network device and a core network device.

[0088] Specifically, the second device may send a first request message to the first device based on the data request of the data consumer device, where the first request message is used to request establishment of a data plane connection between the first device and the target device, or to obtain data based on the data plane connection.

[0089] Optionally, establishing the data plane connection may be selecting a path on an existing path between the first device and the target device and establishing the data plane connection, or directly creating a path between the first device and the target device and establishing the data plane connection. The first device establishes a data plane connection with the target device based on the first request message. Optionally, the target device may be the second device, or another device in the network domain to which the second device belongs, such as another network element of the core network.

[0090] For example, the first device is a terminal, the second device can be a core network device (such as DPF-C), and the target device can be a core network device (such as DPF-U); the first device is an access network device, the second device is a core network device (such as DPF-C), and the target device is a core network device (such as DPF-U).

[0091] For example, the first device is a terminal, the second device may be an access network device, and the target device may be an access network device or a core network device.

[0092] In the method of this embodiment, a first device receives a first request message from a second device; the first device establishes a data plane connection with a target device based on the first request message, thereby realizing the establishment of a data plane connection between the first device and the target device, with low implementation complexity.

[0093] Optionally, the first request message includes at least one of the following: first path information of data plane control signaling; second path information of data plane data forwarding; a first data encoding method; and a first data encryption method.

[0094] Specifically, the first path information, the second path information, the first data encoding method, and the first data encryption method included in the first request message may be selected or determined by the second device.

[0095] The following description is made by taking the first device as a terminal and the second device as a core network device as an example, for example, the second device is a DPF:

[0096] 1. First path information of data plane control signaling selected by DPF: indicates the first path information preferred by DPF-C to the terminal. The first path is used to transmit data plane related control signaling.

[0097] Optionally, the first path may be expressed as: a CP plane path, a data plane control DP-C plane path. The first path may also be expressed as the protocol layers that the data plane signaling needs to pass through (such as NAS-PDCP-layer 2 protocol-layer 1 protocol, or DsP1-C-PDCP-layer 2 protocol-layer 1 protocol).

[0098] 2. Information about the second path selected by the DPF for forwarding data plane data: indicates to the terminal information about the second path preferred by the DPF-U, which is used to forward data plane data.

[0099] Optionally, the second path may be expressed as: CP plane path, UP plane path, data plane forwarding DP-U plane path. The second path may also be expressed as the protocol layer that needs to be passed through for forwarding data plane related data (such as NAS-PDCP-layer 2 protocol-layer 1 protocol; or, SDAP-PDCP-layer 2 protocol-layer 1 protocol; or, DsP1-U-PDCP-layer 2 protocol-layer 1 protocol).

[0100] 3. The first data encoding method selected by the DPF includes but is not limited to the data serialization method used to instruct the terminal to use when reporting data, such as ASN.1, Protobuf, JSON, and others.

[0101] 4. The first data encryption mode selected by the DPF includes but is not limited to indicating whether the data reported by the terminal needs to be encrypted.

[0102] In the above implementation, by including at least one of the following items in the first request message: first path information of data plane control signaling; second path information of data plane data forwarding; first data encoding method; first data encryption method, the establishment of a data plane connection between the first device and the target device can be achieved with low implementation complexity.

[0103] Optionally, a data consumer device (e.g., another terminal, a service function (SF), or an AF) requests a second device (e.g., a DPF-C) to obtain data, for example, by using a second request message to request the data. The second request message may include at least one of the following:

[0107] Data scope, which limits the time range and regional range of data acquisition;

[0108] Data reporting conditions;

[0109] Additional information.

[0110] Optionally, the second device (eg, DPF-C) responds to the request of the data consumer device, and the response message indicates whether to accept the request of the data consumer device to obtain data; if rejected, the process ends.

[0111] It should be noted that DPF-C can be a newly defined network element or an existing 5G network element responsible for data collection, such as the Data Collection Coordination Function (DCCF) network element.

[0112] Optionally, the first request message may be a first request message from the second device forwarded by another device, for example, a downlink NAS message is sent to the first device through the AMF, and the content of the first request message is carried in the downlink NAS message.

[0113] Optionally, the second device may send the first request message to the AMF through Namf_Communication_N1N2MessageTransfer signaling.

[0114] Optionally, the method further includes:

[0115] The first device determines first information;

[0116] The first device establishing a data plane connection with the target device based on the first request message, including:

[0119] Specifically, after receiving the first request message, the first device determines the first information and establishes a data plane connection with the target device based on the first information.

[0120] Optionally, the first path information or the third path information includes at least one of the following: control plane path indication information, user plane path indication information, data plane control path indication information, and information about protocol layers that data plane signaling needs to pass through.

[0121] Optionally, the second path information or the fourth path information includes at least one of the following: control plane path indication information, user plane path indication information, data plane forwarding path indication information, and information about protocol layers that the data plane needs to pass through when forwarding data.

[0122] The control plane path indication information may be, for example, information related to the CP path, the user plane path indication information may be, for example, information related to the UP path, the data plane control path indication information may be information related to the DP-C path, and the data plane forwarding path indication information may be information related to the DP-U path. It is understood that the control plane path indication information may be information indicating the CP path, the user plane path indication information may be information indicating the UP path, the data plane control path indication information may be information indicating the DP-C path, and the data plane forwarding path indication information may be information indicating the DP-U path.

[0128] Specifically, the first device determines the third path information of the data plane control signaling based on a first factor. The first factor includes at least one of the following:

[0129] (1) Forwarding delay requirements for data plane control signaling. For example, when the delay requirement is high, the data plane control signaling path needs to streamline protocol layers, skip encryption and decryption, etc. In this case, the protocol stack corresponding to the newly defined streamlined DP plane path or the CP plane protocol stack can be used; conversely, the data plane control signaling path can utilize the UP plane protocol stack.

[0130] (2) Whether the data plane control signaling needs to be parsed by the access network equipment RAN. For example, when it needs to be parsed by the RAN, the signaling needs to be processed by the RAN data plane peer protocol layer (such as DsP, DsP1, PDCP, Layer 2 protocol, Layer 1 protocol; or DsP, DsP1, RRC, PDCP, Layer 2 protocol, Layer 1 protocol); otherwise, the signaling does not need to be processed by the RAN data plane peer protocol layer (such as DsP, PDCP, Layer 2 protocol, Layer 1 protocol; or DsP, NAS, RRC, PDCP, Layer 2 protocol, Layer 1 protocol, etc.).

[0131] Optionally, the first device may determine the third path information based on the first request message and the first factor, for example, determine the third path information based on the first path information in the first request message and the first factor.
