Generally, the data open function is deployed in a centralized unit (CU) or access and mobility management function (AMF) of a base station, and the connection function can be deployed in a distributed unit (DU) of a base station, and other locations. Consumer devices include but are not limited to core network elements or third-party applications or terminals.

[0087] In an embodiment of the present invention, the data open function has a security anchor function for data openness on the RAN side, which can map the needs of the consumer device to the terminal, send a data open instruction to the terminal, and request the terminal to provide data open services. At the same time, after the terminal provides the data open service, when the consumer device obtains the terminal data, the data open function can also serve as a functional anchor point for the terminal to provide data information to the consumer device, obtain the terminal's data information and report it to the consumer device. The data open instruction instructs the terminal to provide data information open services, wherein the data information includes but is not limited to one or more of link quality information, location information, quality of service (QoS) indicator information (such as the packet loss rate of sent and received data, data transmission rate, etc.), perception / artificial intelligence (AI) information, and vertical industry customized data types. The data open method provided by the embodiment of the present invention can make the consumer device obtain terminal data information with short latency, high efficiency, and high flexibility.

[0088] Optionally, the sending a data opening instruction to the terminal includes:

The data open instruction is issued in the form of a user plane control data packet, and is used to instruct the terminal to provide a data information open service. The user plane control data packet can be a service data adaptation protocol (SDAP) or a protocol layer in the sixth generation mobile communication technology (6G) or a newly introduced service after the access network is serviced. A data open link is established between the consumer device and the terminal through the user plane data packet. The data interaction delay between the data open function and the terminal is shorter, and the flexibility and real-time performance are higher. In addition, the opening of multi-dimensional data (such as AI and perception data) in the future will be more valuable and convenient to the user plane.

[0091] Optionally, the data opening instruction includes:

[0092] A terminal open token, used to indicate that at least one terminal provides data open services;

In general, if Figure 4 As shown, the second user plane control data packet also includes a second sequence identifier, which is used to indicate the sequence of the current message to avoid repeated processing or omission of the message.

[0098] It should be noted that the terminal may send the data information and the data open response separately, or may combine the data information and the data open response into one data packet and send them together.

[0099] Optionally, the receiving a data open response fed back by the terminal according to the data open instruction includes:

[0100] A data open response fed back by the terminal according to the data open instruction is received through a user plane data packet.

[0101] In this embodiment of the present invention, when the data open function receives a data open response from the terminal, the data open response is also reported in the form of a user plane control data packet. The user plane control data packet can be the Service Data Adaptation Protocol (SDAP), a protocol layer in the sixth generation mobile communication technology (6G), or a newly introduced service after the access network is service-oriented. This reduces the latency of data interaction between the data open function and the terminal, and increases flexibility and real-time performance.

[0102] Optionally, before obtaining the data request message sent by the consumer device, the method further includes:

[0103] Obtaining a data subscription request sent by the consumer device, the data subscription request including the type of subscription data and security verification information of the consumer device;

The data opening function first receives the data opening response fed back by the terminal according to the data opening instruction, and then receives the terminal data corresponding to the above data opening response sent by the terminal. After receiving the terminal data, the terminal data is forwarded to the consumer device.

[0111] It should be noted that the terminal may send the terminal data to the data opening function after sending the data opening response, or may carry the terminal data in the data opening response.

[0112] like Figure 5 As shown, an embodiment of the present invention further provides a data opening method, which is applied to a consumer device, comprising:

[0113] Step S501: Send a data request message to a data open function; wherein the data request message is used to request a terminal to provide a data open service, so that the data open function sends a data open instruction to the terminal according to the data request message.

The data open function has a security anchor function for data openness on the RAN side, can map the needs of the consumer device to the terminal, send a data open instruction to the terminal, and request the terminal to provide a data open service. At the same time, after the terminal provides the data open service, when the consumer device obtains terminal data, the data open function can also serve as a functional anchor point for the terminal to provide data information to the consumer device, obtain the terminal's data information and report it to the consumer device. The data information provided by the terminal includes but is not limited to one or more of link quality information, location information, quality of service (QoS) indicator information (such as the packet loss rate of received and transmitted data, data transmission rate, etc.), perception / artificial intelligence (AI) information, and vertical industry customized data types. The data open method provided by the embodiment of the present invention can shorten the latency of the consumer device in obtaining the terminal's data information, increase efficiency, and increase flexibility.

[0154] Step S703: The terminal generates a data open response for the data information to be reported according to the data open instruction, and sends the data open response to the data development function in the form of a user plane data packet. It should be noted that the terminal first sends the data open response to the connection function (not shown in the figure), and the connection function then forwards the data open response to the data open function;

[0155] Step S704: The terminal reports data information to the data opening function;

[0156] Step S705: The data opening function reports data information to the consumer device.

[0157] It should be noted that step S704 may be performed after step S703 or may be sent together with the data open response in step S703.

[0158] like Figure 8 As shown, before step S702, the data open function and the terminal need to establish an RRC connection for information exchange through the connection function. The process of establishing the RRC connection is described below:

[0159] Step S801: The base station sends a first message to the terminal via system message broadcast or multicast, where the first message indicates the terminal's need to create a data open service.

[0160] Step S802: The terminal sends an RRC establishment request to the base station according to the first message, where the RRC establishment request includes a first request for establishing a terminal data open service;

[0161] Step S803: The base station sends an RRC establishment response to the terminal, where the RRC establishment response includes a first response corresponding to the first request.

[0162] It should be noted that steps S801 to S803 may occur before step S701 or after step S701.

[0163] like Figure 9 As shown, before step S701, the consumer device can subscribe to data, and the data open policy obtains the data open policy according to the data subscription request. The terminal periodically reports data according to the data open policy. The data open policy can be formulated locally or through the PCF. The data subscription steps of formulating the data open policy through the PCF are described below:

[0164] Step S901: The consumer device sends a data subscription request to the data open function, where the data subscription request includes the type of subscription data and security verification information of the consumer device;

[0165] Step S902: The data open function interacts with the PCF according to the data subscription request to obtain the data open policy.

[0166] Step S903: Send a data subscription response to the consumer device according to the data open policy.

[0167] like Figure 10 As shown, the present invention is described through a specific embodiment. In this embodiment, the terminal and the data open function interact through the connection function of the base station. The terminals include terminal 1 and terminal 2. The connection function is the distribution unit DU of the base station, including the distribution unit DU1 corresponding to terminal 1 and the distribution unit DU2 corresponding to terminal 2. The data open function is deployed in the centralized unit CU of the base station. The consumer device is an extended reality (Extended Reality, XR) third-party application, which requests the terminal location information within the geographical area of ​​the base station to optimize the quality of XR services. The following is an explanation through specific steps:

[0168] Step S1001: A third-party application sends a data subscription request to a CU, including the requested data type being location data and security verification information of a consumer device;

[0169] Step S1002: The CU sends a data subscription response to the third-party application based on the locally configured data open policy.

[0170] Step S1003: The third-party application sends a data request message to the CU to request data information of the terminal;

[0171] Step S1004: The CU forwards the data request message to DU1 and DU2 respectively, instructing DU1 and DU2 to send a first message, where the first message is used to indicate the terminal's need to create a data open service.

[0172] Step S1005: DU1 and DU2 broadcast a first message via a system message, and Terminal 1 and Terminal 2 can receive the first message. The first message includes positioning data, data type ID, and minimum channel quality threshold, etc.

[0173] Step S1006: After receiving the first message, Terminal 1 sends an RRC establishment request to DU1, where the RRC establishment request includes a first request for requesting an open positioning data type ID.

[0174] Step S1007: After receiving the first message, Terminal 2 sends an RRC establishment request to DU2, where the RRC establishment request includes a first request for requesting an open positioning data type ID.

[0175] Step S1008: After receiving the RRC establishment request sent by terminal 1, DU1 sends an RRC establishment response to terminal 1. The RRC establishment response includes a first response corresponding to the first request, and the first response includes a terminal group ID and a positioning data type ID.

[0176] Step S1009: After receiving the RRC setup request sent by terminal 1, DU2 sends an RRC setup response to terminal 2. The RRC setup response includes a first response corresponding to the first request, and the first response includes a terminal group ID and a positioning data type ID.

[0177] Through the above steps, the data open function, i.e., CU, can obtain the data information of the terminal through the connection function, i.e., DU1 / DU2. In the embodiment of the present invention, CU first obtains the data information of terminal 1. The acquisition process is described below:

[0178] Step S1010: The CU generates a data open instruction based on the data request message in S1003, and sends the data open instruction to the terminal 1 via DU1 in the form of a user plane control data packet. The data open instruction also includes a first sequence identifier, a terminal open token, i.e., the ID identifier of the terminal 1, and a data request message, i.e., the data type is positioning data.

[0179] Step S1011: Terminal 1 generates a data open response according to the data open instruction. In this embodiment, the data open response includes data information that the terminal needs to report. The data open response is sent to the CU via DU1 in the form of a user plane control data packet. The data open response includes terminal identity information and data information of the data open information terminal. The data open response also includes a second sequence identifier. The terminal identity information is the ID of terminal 1, and the data open information is the data volume of the data information reported this time.

[0180] Step S1012: CU sends data information to a third-party application;

[0181] When terminal 1 moves to the edge of the base station's geographical area, the link quality is poor and it cannot provide the required data information. Terminal 2 is selected as the new data provider. The following describes the process of obtaining terminal 2's data information:

[0182] Step S1013: The CU generates a data open instruction based on the data request message in S1003, and sends the data open instruction to the terminal 2 via DU2 in the form of a user plane control data packet. The data open instruction includes the first sequence identifier, the terminal open token, which is the ID of the terminal 2, and the data request message, which is the data type of positioning data and updated positioning calibration data.

[0183] Step S1014: Terminal 2 generates a data open response according to the data open instruction. In this embodiment, the data open response includes the data information that the terminal needs to report. The data open response is sent to the CU via DU2 in the form of a user plane control data packet. The data open response includes the terminal identity information and the data information of the data open information terminal. The data open response also includes a second sequence identifier. The terminal identity information is the ID of terminal 2, and the data open information is the data volume of the data information reported this time.

[0184] Step S1014: The CU sends data information to a third-party application.

[0185] In summary, by adopting the embodiment of the present invention, the data open function can instruct at least one terminal to provide data open services to consumer devices, and instruct the terminal to report data information in the form of user-side data packets, thereby reducing data delay and having higher real-time performance and flexibility.
