Detailed Implementation

[0040] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0041] The user plane positioning method provided in this application can be applied to... Figure 1 The diagram shows a schematic of the communication system architecture. Figure 1 As shown, the communication system includes: access network equipment and multiple terminal devices. It is assumed that the multiple terminal devices include terminal device 1, terminal device 2, terminal device 3, and terminal device 4 in the diagram. It should be noted that... Figure 1 The communication system shown can be applied to different network standards, such as Global System for Mobile communication (GSM), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Time Division-Synchronous Code Division Multiple Access (TD-SCDMA), Long Term Evolution (LTE) systems, and future 5G network standards. Optionally, the above communication system can be used in scenarios involving Ultra-Reliable and Low Latency Communications (URLLC) transmission within 5G communication systems.

[0042] Therefore, optionally, the aforementioned base station can be a base station (BTS) and / or base station controller in GSM or CDMA, a base station (NodeB, NB) and / or radio network controller (RNC) in WCDMA, an evolved Node B (eNB or eNodeB) in LTE, a relay station or access point, or a base station (gNB) in future 5G networks, etc., which are not limited herein.

[0043] The aforementioned terminal devices can be either wireless or wired. A wireless terminal can be a device that provides voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core network devices via a Radio Access Network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device, which exchanges voice and / or data with the RAN. Furthermore, a wireless terminal can also be a Personal Communication Service (PCS) phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), or other similar devices. A wireless terminal can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station, remote station, remote terminal, access terminal, user terminal, user agent, user device, or user equipment; no specific terminology is used here. Optionally, the aforementioned terminal devices can also be smartwatches, tablets, or other similar devices.

[0044] In existing 3GPP positioning technologies, the user terminal itself or a third-party application, such as an AF / LCS client, needs to initiate a positioning request to the user terminal. The former is called Mobile Originated-Location Report (MO-LR), and the latter is called Mobile Terminated-Location Report (MT-LR). Both MO-LR and MT-LR are control plane positioning methods. That is, the user terminal accesses signaling interactions with mobility management function network elements, positioning gateways, positioning management function network elements, and other devices and network elements, carrying relevant location information to complete the location calculation. The general process of MO-LR is as follows: (1) The user terminal completes the registration process in the network; (2) The user terminal initiates a service request to establish a signaling channel with the access and mobility management function network element; (3) The user terminal initiates an MO-LR request process to request the network to locate it; (4) The access and mobility management function network element selects a suitable location management function network element and requests the location management function network element to locate the user terminal; (5) The location management function network element locates the user terminal and returns the location result to the access and mobility management function network element; (6) The access and mobility management function network element sends the location result to the location gateway; (7) The location gateway sends the location result directly to the location server or to the application function through the Network Exposure Function (NEF); (8) The location server or the application function returns a response message, which is returned to the access and mobility management function network element through the location gateway and then further returned to the user terminal.The general process of MT-LR is as follows: (1) The user terminal completes the registration process in the network; (2) The location server or application function initiates the MT-LR request process and sends it to the location gateway to request the network to locate the relevant user terminal; (3) The location gateway sends a request to the Unified Data Management (UDM) to query the context information and privacy check information of the user terminal; (4) The Unified Data Management returns relevant information, which includes the access and mobility management function network element information currently serving the user terminal; (5) The location gateway sends the location request to the corresponding access and mobility management function network element; (6) The access and mobility management function network element selects the appropriate location management function network element and requests the location management function network element to locate the user terminal; (7) The location management function network element locates the user terminal and returns the location result to the access and mobility management function network element; (8) The access and mobility management function network element sends the location result to the location gateway; (9) The location gateway sends the location result directly to the location server or to the application function through the network capability opening function. Both MO-LR and MT-LR are control plane positioning methods, which involve the user terminal accessing and communicating with mobility management function network elements, positioning gateways, positioning management function network elements, and other devices and network elements to carry relevant location information and complete the location calculation.

[0045] One example proposes a user plane positioning approach. The overall idea is to add a new user plane positioning network element or a functional module integrated into the positioning management function network element. By establishing a dedicated user plane channel from the user terminal to this positioning network element or functional module, the user plane positioning information between the user terminal and this positioning network element or module can be transmitted. This approach utilizes existing Secure User Plane Location (SUPL) technology, as well as existing Lightweight Presentation Protocol (LPP), Non-Access Stratum (NAS), and NR Positioning Protocol A (NRPPa) messages to carry the user plane positioning information.

[0046] However, implementing the above methods requires the creation of a dedicated user plane channel, which involves significant changes and makes network upgrades difficult.

[0047] The user plane positioning method provided in this application aims to solve the above-mentioned technical problems of the prior art.

[0048] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0049] Figure 2 This is a flowchart illustrating a user plane positioning method provided in an embodiment of this application. The method is applied to user plane functional network elements, such as... Figure 2 As shown, the method includes:

[0050] 101. Receive session request information, wherein the session request information is used to instruct the user plane function network element to establish or update a protocol data unit session for the user terminal, and the session request information includes the location indication identifier of the user terminal.

[0051] For example, the user plane function network element receives session request information, such as session establishment request information or session update request information. The session request information is used to instruct the user plane function network element to establish or update a protocol data unit session for the user terminal. The session request information includes the location indication identifier of the user terminal.

[0052] 102. Generate a protocol data unit session based on the session request information, and obtain the user terminal's location information based on the protocol data unit session, wherein the location information includes one or more of the following: location method information, location condition information, and location accuracy information.

[0053] For example, based on the received session request information, a Protocol Data Unit (PDU) session is established or modified, response information is returned to the access and mobility management function network element and the user terminal, and the location information of the user terminal is obtained based on the PDU session. The location information includes one or more of the following: location method information, location condition information, and location accuracy information.

[0054] 103. Transmit the location information to the location management function network element to instruct the location management function network element to locate the user terminal, wherein the location management function network element is used to determine the location result of the user terminal based on the location information.

[0055] For example, the acquired location information of the user terminal is transmitted to the corresponding location management function network element, and then the location management function network element can calculate the location information, determine the location result of the user terminal, and realize the location of the user terminal.

[0056] In summary, the user plane positioning method provided in this embodiment involves the following steps: receiving session request information, wherein the session request information is used to instruct the user plane function network element to establish or update a protocol data unit session for the user terminal, and the session request information includes a positioning indication identifier of the user terminal; generating a protocol data unit session based on the session request information, and obtaining the positioning information of the user terminal based on the protocol data unit session, wherein the positioning information includes one or more of positioning method information, positioning condition information, and positioning accuracy information; and transmitting the positioning information to the positioning management function network element to instruct the positioning management function network element to locate the user terminal. This process does not require adding new channels and can efficiently and simply achieve user plane positioning based on the existing network architecture.

[0057] Figure 3 This is a flowchart illustrating another user plane positioning method provided in an embodiment of this application. The method is applied to user plane functional network elements, such as... Figure 3 As shown, the method includes:

[0058] 201. Receive session request information, wherein the session request information is used to instruct the user plane function network element to establish or update a protocol data unit session for the user terminal, and the session request information includes the location indication identifier of the user terminal.

[0059] For example, the user plane function network element receives session request information, such as session establishment request information or session update request information, sent by the session management function network element (SMF). The session request information is used to instruct the user plane function network element to establish or update a protocol data unit session for the user terminal, including the location indication identifier of the user terminal.

[0060] In one example, before the user plane function network element receives the session request, the following steps are also included: (1) The access and mobility management function network element receives a location request sent by the location server or application function. Optionally, this location request message carries an identifier indicating that the user terminal has user plane information location capabilities. The user terminal can report its user plane location capabilities during the registration process, or the access and mobility management function network element can obtain them by querying the user terminal's subscription information in the unified data management; (2) The access and mobility management function network element selects a location management function network element; (3) The access and mobility management function network element sends the location request message to the location management function network element. (3) The user terminal supports user plane positioning capability and informs the location management function network element; (4) The location management function network element decides to use user plane to transmit location information; (5) The location management function network element returns a location confirmation message to the access and mobility management function network element, carrying a user plane positioning requirement identifier, indicating that user plane positioning is required; (6) The access and mobility management function network element returns a location response message to the user terminal, carrying a user plane positioning identifier, requesting the user terminal to perform user plane positioning operation; (7) The user terminal initiates a PDU session establishment or update request itself or through the trigger of the access and mobility management function network element. The PDU session is established or updated for user plane positioning, and carries an indicator to indicate that the PDU session is established or updated for user plane positioning. (8) The access and mobility management function network element sends a session establishment or session update request to the session management function network element, which carries an indicator to indicate that the PDU session is established or updated for user plane positioning. (9) The session management function network element sends a Packet Forwarding Control Protocol (PFCP) session establishment request or PFCP session modification request message to the user plane function network element according to the received request message. The user plane function network element is requested to create or update a PDU session for the user terminal, which carries an indicator to indicate that the PDU session is established or updated for user terminal positioning.

[0061] 202. Based on the session request information, establish or update the protocol data unit session with the user terminal.

[0062] For example, based on the session request information, a protocol data unit session is established or updated with the user terminal, and response information for session establishment or session update is returned to the access and mobility management function network element and the user terminal.

[0063] 203. Based on the protocol data unit session, obtain the location information sent by the user terminal, wherein the location information includes one or more of the following: location method information, location condition information, and location accuracy information.

[0064] For example, the user terminal sends location information to the user plane function network element based on the established or updated PDU session. The user plane function network element receives and obtains the location information based on the protocol data unit session. The location information includes location method information, location condition information, and location accuracy information, etc.

[0065] In one example, the location information of the user terminal is determined through location management function network element and the user terminal location communication.

[0066] 204. Transmit the location information to the location management function network element to instruct the location management function network element to locate the user terminal, wherein the location management function network element is used to determine the location result of the user terminal based on the location information.

[0067] In one example, step 204 includes the following four implementation methods:

[0068] The first implementation involves sending the location information to the session management function network element, and then transmitting the location information to the location management function network element based on the session management function network element, so as to instruct the location management function network element to locate the user terminal.

[0069] The second implementation method involves storing the location information in a buffer; if the preset triggering conditions are met, the location information is sent to the session management function network element, and based on the session management function network element, the location information is transmitted to the location management function network element to instruct the location management function network element to locate the user terminal.

[0070] In the third implementation method, both the user plane function network element and the location management function network element support the event notification function. Based on the event notification function, the location information is sent to the location management function network element to instruct the location management function network element to locate the user terminal.

[0071] The fourth implementation method involves a preset logical interface between the user plane function network element and the location management function network element; location information is sent to the location management function network element to instruct the location management function network element to locate the user terminal.

[0072] For example, there are four ways to transmit location information to the location management function network element: First, the location information is sent to the session management function network element via a session report process, and then the session management function network element transmits the location information to the location management function network element. Second, the location information is stored in a buffer; if a preset trigger condition is met, such as when a user plane location information receiving end marker is received or the buffer reaches a storage threshold, the location information is sent to the session management function network element, and then the session management function network element transmits the location information to the location management function network element. Third, when the location management function network element subscribes to an event exposure service, and both the user plane function network element and the location management function network element support the event exposure service, the user plane function network element can send the location information to the location management function network element based on the transmission of event exposure messages. The fourth implementation method involves a pre-defined logical interface between the user plane function network element and the location management function network element. For example, the N6 peer port of the user plane function network element is the location management function network element. The user plane function network element can send the received location information of the user terminal to the location management function network element based on this interface. After receiving the location information of the user terminal, the location management function network element can calculate the location information, determine the location result of the user terminal, and realize the location of the user terminal.

[0073] In summary, the user plane positioning method provided in this embodiment offers multiple implementation methods for transmitting user terminal positioning information based on PDU session transmission. It does not require adding new channels and can efficiently and simply achieve user plane positioning on the basis of the existing network architecture.
