[0105] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0106] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such terms can be used interchangeably where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same class, not limited in number; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0107] To facilitate understanding of the technical solution of this application, the following technical points are introduced:

[0108] Positioning systems in related technologies include:

[0109] i. Location Service (LCS) systems defined by the 3rd Generation Partnership Project (3GPP) standards organization.

[0110] ii. Secure User Plane Location (SUPL) system as defined in the Open Mobile Alliance (OMA) standards organization.

[0111] iii. The converged location services architecture defined by the 3GPP standards organization.

[0112] v.3GPP LCS Location Services System, defined by the 3GPP standards organization as the Application Enablement Layer Location Management Architecture.

[0113] When a location service is initiated, the location system needs to determine the location method or technology to be used. Location methods or technologies include those used with the same network infrastructure (e.g., New Radio (NR) networks), such as NR Enhanced Cell-ID (E-CID), NR Down Link (DL) Time Difference of Arrival (TDOA), NR DL Angle Departure (AoD), and NR Multi-Round-Trip Time (RTT). In determining the location method or technology, the network needs to know the location methods or technologies supported by the terminal (i.e., one of the location capabilities), and location capability negotiation is required between the network and the terminal.

[0114] For fusion positioning systems that use multiple positioning systems as positioning input sources (such as NR networks, Bluetooth networks, WiFi networks, and Visual Simultaneous Localization and Mapping (vSLAM) systems), in addition to the positioning method or technology, the location service initiation also requires determining which positioning system(s) to use as the positioning data source. Similarly, the network and the terminal also need to negotiate the supported positioning system capabilities (one type of positioning capability).

[0115] LCS and SUPL systems are positioning sources that can support multiple positioning methods or technologies.

[0116] LCS supports positioning methods or technologies including Observed Time Difference of Arrival (OTDOA) (based on Long Term Evolution (LTE) signals), Assisted-Global Navigation Satellite System (A-GNSS), E-CID (based on LTE signals), sensors, TBS, Wireless Local Area Network (WLAN), Bluetooth, NR E-CID, NR DL-TDOA, NR DL-AoD, and NR Multi-RTT positioning technologies.

[0117] In addition to those supported by LCS, the positioning methods or technologies supported by SUPL include Enhanced Observed Time Difference (EOTD), WLAN Enhanced Cell ID, image recognition-based positioning, and short-range node positioning technologies.

[0118] I. About the 3GPP LCS System Architecture

[0119] like Figure 1 As shown, during the LCS location service initiation process, the determination of the positioning method and the negotiation of positioning capabilities between the terminal and the network are carried out through the interaction between the UE and the Location Management Function (LMF) (see Appendix 1 for the specific process). The positioning method is determined by the 3GPP network. The positioning method adopted by the network and the terminal can be reported together with the location report by the location service initiator (Application function (AF) or Location Service Client), that is, the location service initiator can only be informed after the positioning process.

[0120] II. Regarding the OMA SUPL system architecture

[0121] like Figure 2 As shown, during the SUPL location service initiation process, the determination of the positioning method and the negotiation of positioning capabilities between the terminal and the network are carried out through the interaction between the terminal (SET) and the SLP (see Appendix 2 for the specific process). The positioning method is determined by the SUPL Location Platform (SLP), and the positioning method adopted by the network and the terminal is determined before the positioning process.

[0122] III. On the Architecture of the Integrated Location Service System

[0123] like Figure 3 As shown, the fused location client is the location service module for the positioning terminal.

[0124] The Fused location function is the core service network element of the Fused location service system, supporting location and location service interaction with the Fused location client. It supports interfacing with multiple location systems, including one of the two network elements of the 5G core network: Network Exposure Function (NEF) or Gateway Mobile Location Center (GMLC), and / or includes the SUPL location platform SLP, and / or includes a third-party location server.

[0125] Application-specific servers are for users and consumers of converged location services.

[0126] IV. On the Application Enablement Layer Location Management Architecture

[0127] See Figure 4 The location management client is the location management module of the terminal.

[0128] The location management server provides location management functions and supports location management interaction with the location management client. It supports interfacing with multiple positioning systems, including one of the two network elements of the 5G core network: NEF or GMLC, and / or includes the SUPL positioning platform SLP, and / or includes servers of third-party positioning systems.

[0129] Application-specific servers are for users and consumers of converged location services.

[0130] For the use of non-cellular positioning technologies such as Bluetooth and WiFi, some positioning systems may have limitations in network access. Especially for vertical industry applications with complex positioning environments and network deployments, requiring the simultaneous use of multiple positioning systems and methods, there is a lack of mechanisms for unified capability negotiation, positioning service configuration, and positioning service invocation for terminals and positioning systems.

[0131] The location network element in this paper refers to a network element capable of providing fusion of one or more positioning methods. These positioning methods include network-based positioning (positioning information calculated by the network is output to the location network element via a positioning system) and terminal-based positioning (positioning information calculated by the terminal is output to the location network element via the terminal or via a positioning system), and also include the fusion of multiple positioning information types. The location network element can provide the application server with the location information of the positioning terminal. The location network element can also serve as a network element providing capability open interfaces to the application server within a converged location service platform. Furthermore, the location network element and the application server can interact through an application layer interface.

[0132] The positioning system described in this article can be any system designed to determine the spatial location of a positioning terminal. The positioning system can be an LCS location service system defined by the 3GPP standard, a SUPL location service system defined by the OMA standard, a positioning gateway for Bluetooth systems, a positioning gateway for WiFi systems, a vSLAM server, etc. A positioning terminal can connect to multiple positioning systems simultaneously. The positioning system and the location network element interact through an application layer interface. The positioning system can report location information obtained through network-based positioning methods and terminal-based positioning methods to the location network element.

[0133] The positioning terminal described in this paper can be a terminal capable of providing its own positioning information. The positioning terminal further includes a positioning module and a location service module (the positioning module may be located within or outside the terminal's wireless communication module; the location service module is located outside the wireless communication module and can be located in middleware or the application layer; the location service module may contain the positioning module). The positioning terminal and the location network element interact through an application layer interface.

[0134] The positioning terminal supports reporting its ability to support positioning methods and systems to the location network element. Positioning methods include, but are not limited to: OTDOA (based on LTE signals), A-GNSS, E-CID (based on LTE signals), sensors, TBS, WLAN, Bluetooth, NR E-CID, NR DL-TDOA, NR DL-AoD and NR Multi-RTT positioning technologies, EOTD, WLAN enhanced CELL ID, image recognition-based positioning (such as vSLAM), and short-range node positioning technologies.

[0215] In one embodiment of this application, the positioning capability response further includes: first information, wherein the first information is used to indicate whether the positioning terminal supports the positioning method or positioning technology of the target positioning system, or the first information is used to indicate the positioning method or positioning technology supported by the positioning module of the positioning terminal.

[0216] In one embodiment of this application, the method further includes:

[0217] The system receives location service configuration information sent by a location network element, the location service configuration information including: the association between the identifier of the positioning terminal and the target positioning system information;

[0218] The target positioning system information includes: the network element identifier of the target positioning system.

[0219] In one embodiment of this application, before receiving location service configuration information sent by a location network element, the method further includes:

[0220] Receive a location configuration request sent by a location network element, wherein the location configuration request includes one or more of the following: the identifier of the positioning terminal and location service requirements;

[0221] Send a location configuration response to the location network element.

[0222] In this embodiment of the application, the positioning terminal can send a location server request to the location network element. The location service request is used to assist the location network element in determining the positioning module of the target positioning system or positioning terminal, so that the location network element can provide fused location services to adapt to the location requirements of different application scenarios, positioning environments, and network deployment environments, and improve the positioning accuracy, location service coverage and reliability.

[0223] See Figure 7 The functional entities in the positioning method of this application embodiment include: positioning terminal, positioning system 1, positioning system 2, fused location server and application server.

[0224] A positioning terminal is a terminal that provides its own location information. A positioning terminal may contain a positioning module and a location service module (the positioning module may be located within or outside the terminal's wireless communication module; the location service module is located outside the wireless communication module and can be located in middleware or the application layer; the location service module may contain the positioning module). The positioning terminal and the location server interact through an application layer interface.

[0225] The positioning terminal can report its support capabilities for positioning methods and systems to the converged location server. Positioning methods include, but are not limited to: OTDOA (based on LTE signals), A-GNSS, E-CID (based on LTE signals), sensors, TBS, WLAN, Bluetooth, NR E-CID, NR DL-TDOA, NR DL-AoD and NR Multi-RTT positioning technologies, EOTD, WLAN enhanced CELL ID, image recognition-based positioning (such as vSLAM), and short-range node positioning technologies.

[0226] Positioning systems 1 and 2 are systems designed to determine the spatial location of a positioning terminal. Positioning systems 1 and 2 can be LCS systems defined by the 3GPP standard, SUPL systems defined by the OMA standard, positioning gateways for Bluetooth systems, positioning gateways for WiFi systems, vSLAM servers, etc. It is understood that a positioning terminal can connect to multiple positioning systems simultaneously.

[0227] The positioning systems 1 and 2 interact with the fused location server through an application layer interface. The positioning systems can report location information obtained through network-based positioning and positioning terminal-based positioning methods to the location server.

[0228] A converged location server (CRT) is a server capable of providing fusion of one or more positioning methods. These methods include network-based positioning (outputting location information to the CRT via a positioning system) and terminal-based positioning (outputting location information to the CRT via the terminal), and encompass the fusion of various positioning information. The CRT provides the application server with the location information of the positioning terminals. The CRT can also provide capability-opening interfaces to the application server.

[0229] The location server and application server interact through an application layer interface.

[0230] Application server: This is the server for applications that call location services (including LBS applications, third-party business platform applications, location service partner applications, etc.).

[0231] See Figure 8 The specific steps of the overall location service process are as follows:

[0232] Step 1: Location service registration process between the positioning terminal and the converged location server;

[0233] Step 2: Locate the terminal or trigger location services through the application;

[0234] Step 3: Location capability query process between the positioning terminal and the fused location server;

[0235] Step 4: System positioning configuration process between positioning terminal, positioning system and fused location server;

[0236] Step 5: Configure terminal location services between the positioning terminal, positioning system, and converged location server;

[0237] Step 6: The fused location server sends a location service configuration notification to the positioning system;

[0238] Step 7: Location information reporting and location calculation process between the positioning terminal, positioning system, and fused location server;

[0239] Step 8: Location service response process between the positioning terminal, positioning system, converged location server and application.

[0240] The embodiments of this application are described below with reference to examples.

[0241] (a) Corresponding location service system:

[0242] The location service module of the positioning terminal is a fused location client.

[0243] The positioning system includes: one of the two network elements of the 5G core network: NEF or GMLC, and / or includes the SUPL positioning platform SLP, and / or includes a server of a third-party positioning system.

[0244] The location network element is a fused location function entity.

[0245] The application server is an application-specific server.

[0246] The third-party positioning system can be: Bluetooth system; WiFi system; UWB system; vSLAM; satellite system.

[0247] (b) Corresponding to location management systems based on application enablement layers:

[0248] The location service module of the positioning terminal is a location management client.

[0249] The positioning system includes 3GPP network systems, and / or includes the SUPL positioning platform SLP, and / or includes servers of third-party positioning systems.

[0250] The location server is a location management server.

[0251] The application server is a Vertical Application Layer (VAL) server.

[0252] The application can be a location management client for the terminal that invokes the location service.

[0253] Example 1a: Location service registration process in a fused location service system:

[0254] See Figure 9 The specific steps are as follows:

[0255] Step 1: The merged location client sends a location service registration request to the merged location server. The location service registration request includes:

[0256] - The identifier for the positioning terminal can be a Generic Public Subscription Identifier (GPSI), a Mobile Station International Service Digital Network (MSISDN) / telephone number, or a Universally Unique Identifier (UUID);

[0257] Optionally, it includes:

[0258] -User ID;

[0259] - Positioning technologies or systems supported by the terminal (e.g., LCS, SUPL, Bluetooth, WiFi, UWB, vSLAM, satellite positioning, etc.).

[0260] Step 2: Merge the location server to perform location service authorization and location privacy checks.

[0261] If the location service registration request only includes a terminal identifier, the converged location server can initiate an interaction with the core network 5GC to perform location privacy checks and related authorizations for the terminal. If the location service registration request includes a user identifier, the converged location server can also perform user location privacy checks and related authorizations based on the user identifier, and securely associate the user identifier and the terminal identifier.

[0262] Step 3: The converged location server sends a location service registration response to the converged location client. The location service registration response includes the supported location service modes.

[0263] Example 1b illustrates the application layer enabling the location service registration process in the location management system. Specific steps can be found in [reference needed]. Figure 10 .

[0264] It should be noted that in Example 1b Figure 10 Compared with Example 1a Figure 9 The difference in the process shown is that the merged location client is replaced with a location management client, and the merged location server is replaced with a location management server.

[0265] Example 2a: The registration process of merged location services in a merged location service system:

[0266] See Figure 11 The specific steps are as follows:

[0267] Step 1a: The converged location server receives a location service request from the application, which includes one or more of the following:

[0268] -Identification of the positioning terminal

[0269] -User ID;

[0270] - Location service modes, which include one or more of the following: (a) active location query; (b) historical trajectory query; (c) real-time location tracking; (d) route planning; (e) point of interest positioning; (f) electronic fence; (g) indoor navigation; (h) location analysis.

[0271] Optionally, the location service request may also include:

[0272] - The application / service identifier that invokes this location service;

[0273] - The application's requirements for this location service (such as positioning accuracy – including horizontal and vertical accuracy, positioning latency, confidence level / confidence rate);

[0274] -Location environment (e.g., indoor or outdoor environment, urban canyon environment, highway, tunnel, etc.);

[0275] -Location area (such as the administrative region or geographical area where the location is being located);

[0276] -Location priority information;

[0277] - Application types (e.g., emergency operations, real-time location tracking, cargo tracking, robot navigation, location data analysis, etc.).

[0278] Step 1b: The converged location server receives a location service request from the converged location client. The location service request contains its own identification information (terminal identifier or user identifier); the location service request may contain other information as described in step 1a.

[0279] Step 2 / 3: If the converged location server does not have location system information supported by the converged location client, it sends a Location Capability Request to the converged location client to query the location capability of the UE being located.

[0280] If the converged location server decides which location methods need to be used, it can include the queried location methods (such as GNSS, Bluetooth, WiFi, etc.) in the location capability request. The converged location client then indicates whether these location methods are supported in the location capability response.

[0281] Location capability requests may not include a specific location method; in this case, the merged location client will include the currently available location methods in the location capability response.

[0282] It is understandable that steps 2 / 3 may occur before steps 1a and 1b, or steps 1b may include the UE positioning capability information queried in steps 2 / 3.

[0283] Step 4: The fusion location server can identify and determine the location network that needs to be configured based on the information obtained in steps 1a, 1b and step 3.

[0284] The location network system may have already been configured by the network operator (e.g., LCS, SUPL). If the location network system is configured via a converged location server, the converged location server will activate the corresponding location network system (e.g., notify a third-party location server to activate the measurement equipment of the corresponding network).

[0285] If the decision is made to use LCS for location, then existing technology will be employed, and the location server will initiate a network-based location process to 5GC. Steps 5-9 are omitted.

[0286] If the decision is made to locate via SUPL, then existing technology will be used, with the location server acting as an external client to initiate a network-based location process to H-SLP. Steps 5-9 are omitted.

[0287] If it is decided to obtain location information through other third-party location servers, the third-party location servers are notified to activate the corresponding location network system. This process can determine the third-party location server to interact with based on the parameters in steps 1a and 1b, such as the location environment and location area.

[0288] The configuration process integrates the location server to determine the available location network systems and corresponding location methods.

[0289] Steps 5 / 6: The fusion location server configures the positioning terminal (PositioningConfiguration), sending the required positioning method (corresponding to the configuration in step 4) and the corresponding positioning network information (such as the identifier or address of a third-party positioning server: IP address or URI) to the positioning terminal.

[0290] If the location terminal has been configured with the corresponding third-party server information, it can authenticate with the third-party location service through Fused LocationServer (the authentication process can be based on the Fused location client ID) and establish secure communication with the third-party location server.

[0291] Step 7a / b / c: Optionally, the fused location server sends a Location Service Configuration Notification to each positioning system, notifying the relationship between the identifier of the positioning terminal and the location network element information, as well as the positioning mode and related information corresponding to the positioning terminal (which can be identified by the Fused location client ID). The positioning mode refers to the type of positioning mode adopted by each positioning system, such as: single positioning, periodic positioning, event-triggered positioning, etc.

[0292] Optionally, after step 6 and before step 7a, the fusion location server associates the identifier of the positioning terminal with the location network element information configured in steps 4-6.

[0293] Step 8: The positioning terminal and the positioning system perform a positioning process and report to the fusion location server. The fusion location server can perform a merging or combination calculation process of multiple location information.

[0294] Step 9a / b: The fused location server sends a location service response to the application, which includes the location information of the positioning terminal.

[0295] Example 2b: The registration process for fused location services in the application layer enabling the location management system. Specific steps can be found in [reference needed]. Figure 12 .

[0296] It should be noted that in Example 2b Figure 12 Compared with Example 2a Figure 11 The difference in the process shown is that the merged location client is replaced with a location management client, the merged location server is replaced with a location management server, and the application is replaced with a VAL server.

[0297] Example 3a: Location system configuration process in a fused location service system:

[0298] See Figure 13 The specific steps are as follows:

[0299] Step 1a / b: If the LCS and SUPL have already been configured by the network operator, steps 1 and 2 are omitted. Otherwise, the converged location server sends a Location Capability Request to the NEF or GMLC and / or SLP to query the location methods or technologies supported by the location system.

[0300] 2. NEF or GMLC obtains information on the positioning methods supported by LCS. NEF or GMLC can obtain this information through interaction with the 5GC core network.

[0301] Step 2b: SLP responds to the positioning method supported by the SUPL system.

[0302] Step 3: NEF or GMLC responds to the positioning method supported by the LCS system.

[0303] If the decision is made to use LCS for location, the merged location server initiates a network-initiated location process to 5GC.

[0304] If the decision is made to locate via SUPL, the merged location server, acting as an external client, initiates a network-based location process with H-SLP.

[0305] If you decide to obtain location information through other third-party location servers, proceed to steps 4 / 5.

[0306] Steps 4 / 5: If steps 1-3 exist, the merged location server decides whether to initiate location service configuration to other third-party location systems based on the positioning methods or technologies supported by the LCS and / or SUPL systems.

[0307] Furthermore, the third-party positioning system receives a location configuration request from the fusion location server, the location configuration request including one or more of the following: the identifier of the positioning terminal and location service requirements; the fusion location server receives a location configuration response from the third-party positioning system, the location configuration response including the location network element information.

[0308] If the merged location server decides to trigger configuration for a third-party location system, the merged location server will activate the corresponding location network system (e.g., notify the third-party location server to turn on the measurement equipment of the corresponding network).

[0309] The fusion location server sends a location configuration request to a third-party location system and receives a response.

[0310] Example 3b: The registration process for fused location services in the application layer enabling the location management system. Specific steps can be found in [reference needed]. Figure 14 .

[0311] It should be noted that in Example 3b Figure 14 Compared with Example 3a Figure 13 The difference in the process shown is that the merged location client is replaced with a location management client, and the merged location server is replaced with a location management server.

[0312] Example 4: LCS location service system location acquisition method flow, see Figure 14 The specific steps are as follows:

[0313] Step 1: NEF calls the Ngmlc_Location service and sends an Ngmlc_Location_LocationConfig Request message to GMLC to query the location methods supported by the LCS system.

[0314] Step 2: GMLC calls the Nlmc_Location service and sends an Nlmf_Location_LocationConfigRequest message to LMF to query the location methods supported by LMF.

[0315] Step 3: The LMF sends an Nlmf_Location_LocationConfig Response to the GMLC, providing feedback on the location methods supported by the LMF.

[0316] Step 4: GMLC sends an Ngmlc_Location_LocationConfig Response to NEF, providing feedback on the location methods supported by the LCS system.

[0317] It should be noted that if GMLC communicates directly with the location server, steps 1 and 4 can be omitted.
