[0040] Figure 1The block diagram of a wireless communication system to which embodiments of the present application can be applied is shown. The wireless communication system includes a terminal 11 and a network-side device 12. Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a 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, a flight vehicle, a vehicle user equipment (VUE), a shipborne device, a pedestrian user equipment (PUE), a smart home (home devices with wireless communication functions, such as refrigerators, TVs, washing machines or furniture, etc.), a game console, a personal computer (PC), a teller machine or a self-service machine, etc. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle user equipment can also be referred to as a vehicle terminal, a vehicle controller, a vehicle module, a vehicle component, a vehicle chip or a vehicle unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application. The network-side device 12 can include an access network device or a core network device. Among them, the access network device can also be referred to as a radio access network (RAN) device, a radio access network function or a radio access network unit. The access network device can 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, Transmission Reception Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0041] The core network device may include, but is not limited to, at least one of the following: core network node, core network function, Mobility Management Entity (MME), Access and Mobility Management Function (AMF), Session Management Function (SMF), User Plane Function (UPF), Policy Control Function (PCF), Policy and Charging Rules Function (PCRF), Edge Application Server Discovery Function (EASDF), Unified Data Management (UDM), Unified Data Repository (UDR), Home Subscriber Server (HSS), Centralized network configuration (CNC), Network Repository Function (NRF), Network Exposure Function (NEF), Local NEF (L-NEF), Binding Support Function (BSF), Application Function (AF), etc. It should be noted that in the embodiments of this application, only the core network devices in the NR system are taken as examples for introduction, and the specific types of core network devices are not limited.

[0042] First, the technical terms and application scenarios involved in the embodiments of this application are introduced:

[0043] When the network-side device needs to establish a data plane connection with the terminal to obtain data in the terminal, there may be multiple potential paths. For example, the data plane connection can be based on the user plane path (user plane protocol stack), control plane path (control plane protocol stack). Optionally, the data plane connection can also be based on a newly defined data plane path (data plane protocol stack). However, it is currently unclear how to determine and negotiate to select one of the paths to carry the data plane connection between the terminal and the network-side device.

[0044] There may be various data encoding methods for data transmission on the data plane connection between the terminal and the network-side device. Based on data serialization methods such as 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), and each method has its own characteristics, as follows:

[0045] JSON: A lightweight data interchange format, easy to read and write, supports multiple programming languages, and is commonly used in web applications. However, JSON is text-based, with low data encoding and transmission efficiency.

[0046] ASN.1: Has advantages such as compact encoding, type safety, and good interoperability, but requires the use of specialized encoding and decoding tools and rules, with a relatively high implementation difficulty.

[0047] Protocol Buffer: An efficient binary serialization format, supports multiple programming languages, and is commonly used in large-scale distributed systems.

[0048] XML: A markup language used to describe data, supports multiple programming languages, and is commonly used in web applications and data exchange.

[0049] YAML: A human-readable data serialization format, used for configuration files and data exchange, and supports multiple programming languages.

[0050] MessagePack: An efficient binary serialization format, supports multiple programming languages, and is faster and smaller than JSON.

[0051] BSON: A binary JSON format, supports more data types and has better performance, and is commonly used in MongoDB databases.

[0052] However, it is not clear how the terminal and the network-side device select and negotiate data encoding methods according to different requirements.

[0053] Figure 2The data plane architecture is shown. The data plane (DP) connection between the terminal and the network-side device. For example, the terminal is the data source.

[0054] Among them, DP-C and DP-U are two modules related to the data plane inside the terminal:

[0055] 1. DP-C is the data plane control module, which is used to control the signaling related to the establishment, modification, and deletion of the data plane.

[0056] 2. DP-U is the data plane forwarding module, which is used to collect, process, and forward the relevant data inside the terminal.

[0057] Correspondingly, there are corresponding network elements on the core network side (such as the Data Plane Function (DPF)) corresponding to the above two modules inside the terminal:

[0058] 1. DPF-C is the data plane control network element, which is used to control the signaling related to the establishment, modification, and deletion of the data plane.

[0059] 2. DPF-U is the data plane forwarding network element, which is used to collect, process, and forward the relevant data of the terminal, RAN, or other data sources.

[0060] It should be noted that the network elements on the core network side above can be other network element names, or be replaced by other network elements with similar functions, such as the Data Collection Coordination Function (DCCF) network element, or the Messaging Framework Adaptor Function (MFAF).

[0061] Among them, the data plane related signaling of the terminal (i.e., the signaling controlled by the DP-C module) can interact with the DPF-C on the core network side based on different protocol stacks. For example Figure 2 as shown by line 2 in

[0062] 1. Based on the existing CP plane protocol stack (such as the Non-Access Stratum (NAS) and the underlying Access Stratum AS protocol layer);

[0063] 2. Based on the newly added DP protocol stack (such as the Data stratum Protocol 1 (DsP1), the Packet Data Convergence Protocol (PDCP), etc., where DsP1 is the data plane peer protocol layer between the terminal and the RAN);

[0064] It should be noted that the DP plane protocol stack between the terminal and the network side can pass through or not pass through the DsP1 protocol layer.

[0065] When passing through the DsP1 layer, the RAN can parse the DsP1 protocol layer, and can obtain and parse some or all of the information in the data transmitted by the terminal to the core network side, which is beneficial for the data plane module in the RAN to obtain relevant information.

[0066] If not passing through the DsP1, the RAN will transparently transmit the data transmitted by the terminal to the core network side.

[0067] Similarly, the data forwarding of the data plane of the terminal (i.e., the data processed by the DP-U module) can interact with the core network DPF-U based on different protocol stacks. For example Figure 2 as shown by line 1 in

[0068] 1. Based on the CP plane protocol stack (such as NAS and the underlying AS protocol layer);

[0069] 2. Based on the UP plane protocol stack (such as Service Data Adaptation Protocol (SDAP), PDCP, etc.)

[0070] 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 the RAN)

[0071] Among them, the DP plane protocol stack is a newly defined protocol stack exclusive to the data plane, which conforms to the new characteristics of data plane data transmission, such as massive data transmission, large bandwidth, large data segmentation, simple encapsulation format, etc., and streamlined encryption.

[0072] Optionally, Figure 2 DsP1-C and DsP1-U may not exist;

[0073] Optionally, DsP1-C and DsP1-U can be combined;

[0074] Optionally, the two paths of DP-U and DP-C can be combined.

[0075] Optionally, Figure 2 taking the separation of DP-C and DP-U, and the separation of DPF-C and DPF-U as an example, in fact, DP-C and DP-U can be co-located, and DPF-C and DPF-U can also be co-located.

[0076] Optionally, the data source in the embodiments of the present invention includes at least one of the following: terminal, RAN, Core Network Network Function (CN NF), Operation Administration and Maintenance (OAM), data storage network element (such as Analytics Data Repository Function (ADRF)), Application Function (AF), etc. The modules that generate data in the terminal include, but are not limited to, service data modules such as sensing, Artificial Intelligence (AI), location, etc., and basic common data modules. The data source in the RAN may include access network data plane devices. The data source in the CN includes, but is not limited to, sensing functions, data storage functions (such as ADRF), AI-related devices (such as Network Data Analytics Function (NWDAF)), etc. The data source of the AF includes, but is not limited to, trusted AF, untrusted AF, etc. Among them, the data source includes the data source of the access service-based architecture (such as CN NF, OAM, etc.) and the source that is not connected to the service-based architecture (such as terminals, RANs, etc.).

[0077] The data consumer includes at least one of the following: terminal, RAN, CN NF, OAM, ADRF, AF, etc. The data consumer includes the consumers of the access service-based architecture (such as CN NF, OAM, etc.) and the consumers that are not connected to the service-based architecture (such as terminals, RANs, etc.).

[0078] Optionally, the architecture of the embodiments of the present invention may not fully implement network serviceization, that is, some devices or network elements (such as terminals, RANs, certain AFs, etc.) do not implement serviceization, and they still communicate with other devices in the network (including service-based architecture (SBA) network element devices) through point-to-point interfaces.

[0079] For example, when the terminal acts as a data source, during the process of establishing a data plane connection between the terminal, the access network device, and the core network CN, how to agree on the paths and processing methods for signaling and data transfer, etc., so that the CN data plane network element can obtain the corresponding data from the terminal in a suitable and efficient manner is a problem that needs to be solved.

[0080] The following will, in conjunction with the accompanying drawings, elaborate on the method for establishing a data plane connection provided by the embodiments of the present application through some embodiments and their application scenarios.

[0081] Please refer to Figure 3 , the embodiments of the present application provide a method for establishing a data plane connection. The execution entity of this embodiment is a first device, and the method includes:

[0082] Step 101, the first device receives a first request message from a second device;

[0083] Step 102, the first device establishes a data plane connection with a target device based on the first request message.

[0084] Optionally, the first device includes at least one of a terminal and an access network device.

[0085] Optionally, the second device includes at least one of an access network device and a core network device.

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

[0087] Specifically, the second device may, based on the data request of the data consumer device, send a first request message to the first device. The first request message is used to request the establishment of a data plane connection between the first device and the target device, or to obtain data based on the data plane connection.

[0088] Optionally, establishing a data plane connection may be to select a path on an existing path between the first device and the target device and establish a data plane connection, or directly create a path between the first device and the target device and establish a data plane connection. The first device establishes a data plane connection with the target device based on this first request message. Optionally, the target device may be the second device, or other devices in the network domain of the second device, such as other network elements of the core network.

[0089] For example, when the first device is a terminal, the second device may be a core network device (such as DPF-C), and the target device may be a core network device (such as DPF-U); when 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).

[0090] 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.

[0091] In the method of this embodiment, the first device receives a first request message from the second device; the first device establishes a data plane connection with the target device based on the first request message, thereby realizing the establishment of the data plane connection between the first device and the target device, and the implementation complexity is relatively low.

[0092] Optionally, the first request message includes at least one of the following: first path information of the data plane control signaling; second path information of the data plane data forwarding; first data encoding method; first data encryption method.

[0093] 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.

[0094] The following takes the first device as a terminal and the second device as a core network device as an example for illustration. For example, the second device is a DPF:

[0095] 1. First path information of the data plane control signaling selected by the DPF: The first path information preferred by the DPF-C is indicated to the terminal, and the first path is used to transmit data plane related control signaling.

[0096] Optionally, the manifestation forms of the first path include: CP plane path, data plane control DP-C plane path, and the manifestation form of the first path may also be the protocol layers that the data plane signaling needs to go through (such as NAS-PDCP-layer 2 protocol-layer 1 protocol in sequence, or, DsP1-C-PDCP-layer 2 protocol-layer 1 protocol).

[0097] 2. Second path information of the data plane data forwarding selected by the DPF: The information of the second path preferred by the DPF-U is indicated to the terminal, and the second path is used to forward data plane data.

[0098] Optionally, the manifestation forms of the second path include: CP plane path, UP plane path, data plane forwarding DP-U plane path, and the manifestation form of the second path may also be the protocol layers that the data plane related data needs to go through (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).

[0099] 3. First data encoding method selected by the DPF: including but not limited to the data serialization method used to indicate the terminal when reporting data, for example, it may include ASN.1, Protobuf, JSON, etc.

[0100] 4. The first data encryption method selected by the DPF, including but not limited to indicating whether the data reported by the terminal needs to be encrypted.

[0101] In the above implementation, through at least one of the following included in the first request message: the first path information of the data plane control signaling; the second path information of the data plane data forwarding; the first data encoding method; the first data encryption method, the establishment of the data plane connection between the first device and the target device can be realized, and the implementation complexity is relatively low.

[0102] Optionally, a data consumer device (such as other terminals, a service function (SF), or an AF) requests to obtain data from a second device (such as a DPF-C), for example, requests to obtain data through a second request message, and the second request message may include at least one of the following:

[0103] The service type or identifier, such as a sensing service, a location service, an application identifier (APP ID), etc.;

[0104] The type or identifier of the data to be obtained, such as a data type or an event ID, etc.;

[0105] The data object, such as a specific terminal, a terminal list, a terminal group, or any terminal in an area of interest (AOI), etc.;

[0106] The data range, defining the time range, area range, etc. of the data to be obtained;

[0107] The data reporting condition;

[0108] Other information.

[0109] Optionally, the second device (such as a DPF-C) responds to the request of the data consumer device, and indicates in the response message whether it accepts the request of the data consumer device to obtain data; if it refuses, the process ends.

[0110] It should be noted that the DPF-C can be a newly defined network element or an existing 5G network element responsible for data collection, such as a Data Collection Coordination Function (DCCF) network element.

[0111] Optionally, the first request message can be a first request message from the second device forwarded by other devices. For example, the AMF sends a downlink NAS message to the first device and carries the content of the first request message in the downlink NAS message.

[0112] Optionally, the second device may send the first request message to the AMF via Namf_Communication_N1N2MessageTransfer signaling.

[0113] Optionally, the method further includes:

[0114] The first device determines first information;

[0115] The first device establishes a data plane connection with the target device based on the first request message, including:

[0116] The first device establishes a data plane connection with the target device based on the first information;

[0117] Wherein, the first information includes at least one of the following: the third path information of the data plane control signaling; the fourth path information of the data plane data forwarding; the second data encoding method; the second data encryption method.

[0118] 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.

[0119] 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, information on the protocol layers that the data plane signaling needs to go through.

[0120] 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, information on the protocol layers that the data plane forwarding data needs to go through.

[0121] Wherein, the control plane path indication information may be, for example, the relevant information of the CP path, the user plane path indication information may be, for example, the relevant information of the UP path, the data plane control path indication information may be the relevant information of the DP-C path, and the data plane forwarding path indication information may be the relevant information of the DP-U path. It can be understood that the control plane path indication information may be the information indicating the CP path, the user plane path indication information may be the information indicating the UP path, the data plane control path indication information may be the information indicating the DP-C path, and the data plane forwarding path indication information may be the information indicating the DP-U path.

[0122] Optionally, the first path information and the third path information may be the same or different, and the second path information and the fourth path information may be the same or different.

[0123] Optionally, the first device determines first information, including:

[0124] The first device determines third path information of the data plane control signaling based on a first factor, where the first factor includes at least one of the following:

[0125] The forwarding delay requirement of the data plane control signaling;

[0126] Whether the data plane control signaling needs to be parsed by an access network device.

[0127] Specifically, the first device determines the third path information of the data plane control signaling according to the first factor. The first factor includes at least one of the following:

[0128] (1) The forwarding delay requirement of the data plane control signaling. For example, when the delay requirement is high, the path of the data plane control signaling needs to streamline the protocol layer and skip encryption and decryption, etc., then the protocol stack corresponding to the newly defined streamlined DP plane path or the CP plane protocol stack can be used; conversely, the path of the data plane control signaling can use the UP plane protocol stack.

[0129] (2) Whether the data plane control signaling needs to be parsed by a radio access network (RAN) device. For example, when it needs to be parsed by the RAN, the signaling needs to go through the RAN data plane peer protocol layer processing (such as DsP, DsP1, PDCP, layer 2 protocol, layer 1 protocol; or DsP, DsP1, RRC, PDCP, layer 2 protocol, layer 1 protocol); conversely, the signaling does not need to go through the RAN data plane peer protocol layer processing (such as DsP, PDCP, layer 2 protocol, layer 1 protocol; or DsP, NAS, RRC, PDCP, layer 2 protocol, layer 1 protocol, etc.).

[0130] Optionally, the first device may determine the third path information based on a first request message and a first factor, for example, determine the third path information based on the first path information and the first factor in the first request message.

[0196] Specifically, the second device (such as DPF-C) and the third device (such as the policy control network element (such as PCF)) establish / modify the data collection policy association of the data plane corresponding to the first device.

[0207] Among them, the data collection policy information corresponding to the data plane of the first device can be used to indicate how the second device (such as DPF-C and DPF-U) collects data. The data collection policy information corresponding to the data plane of the first device includes at least one of the following information:

Among them, raw data refers to data that has not been processed and maintains the format collected. Processed data refers to data that has undergone data preprocessing. The operations of data preprocessing can be data cleaning, data integration, data reduction, and data transformation, etc.

[0209] An indication of whether it is anonymous, used to indicate whether the collected data is in an anonymous state.

[0217] Specifically, in the case of receiving the first request message, the first device performs data collection. For example, when the first device is a terminal, DP-U processes data according to the first information indicated by DP-C.

[0218] For example, the terminal determines the data type to be collected according to the data type, etc. DP-U collects service data from the upper layer or obtains basic public data from other layers (such as RRC). Further, the scope of data collection needs to conform to the data filtering scope included in the first request message.

[0223] The first device encrypts the data based on the second data encryption method.

[0224] Specifically, DP-U determines a suitable path to forward data plane data according to the fourth path information of data plane data forwarding indicated by DP-C. For example, the UP plane path, CP plane path, or DP plane path is used for data sending. It should be noted here that selecting the data plane forwarding path is also equivalent to selecting the protocol layer that the data forwarding needs to go through.

[0225] Optionally, before forwarding the data, the DP-U performs data encoding representation on the collected data according to the second data encoding method indicated by the DP-C. For example, the data is serialized using ASN.1, protobuf, JSON, etc.

[0226] Optionally, before forwarding the data, the DP-U decides whether to enable the data encryption process according to the second data encryption method indicated by the DP-C.

[0229] Exemplarily, taking the DP-U using the CP plane path for data plane data forwarding as an example, the DP-U processes the collected data according to the selected data processing method, and then encapsulates and processes it layer by layer through the protocol stack corresponding to the CP path and sends it out. The data will reach the DPF-C network element after being forwarded by the RAN and AMF, and the DPF-C network element forwards the data to the DPF-U network element.

[0247] Specifically, the first device sends a response message to the first request message to the second device, and this response message is used to indicate whether the first device accepts the first request message. Optionally, this response message is carried by an uplink NAS message, for example, the first device sends this response message to the second device through a third device (such as AMF).

[0248] If the first device accepts the first request message, the response message may include at least one of the following information:

[0249] The third path information of the data plane control signaling selected by the first device;

[0250] The fourth path information of the data plane data forwarding selected by the first device;
