[0041] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0042] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0043] The outdoor intensive positioning platform provided by the operator provides positioning services for UE based on satellite positioning, 5G positioning and other methods. When the UE is outdoors without obstruction, the outdoor intensive positioning platform can provide the UE with high-precision positioning services. However, when the UE is indoors with obstruction, the positioning service provided by the outdoor intensive positioning platform has the problem of poor positioning accuracy, and cannot provide the UE with height positioning services. For example, in a shopping mall environment, it is difficult to accurately determine the specific location of the UE in the mall based on the outdoor intensive positioning platform, and it is also impossible to determine the height of the floor where the UE is located.

[0044] Some third parties deploy third-party positioning platforms that can achieve indoor high-precision positioning to facilitate the implementation of their services. This disclosure does not limit the method by which the third-party positioning platform achieves indoor positioning. For example, the third-party positioning platform can achieve indoor high-precision positioning based on one or more technologies such as Bluetooth fingerprint, Bluetooth AOA (Angle Of Arrival), WIFI fingerprint, UWB (Ultra Wide Band), vSlam (Visual Simultaneous Localization And Mapping), and can sense the height of the floor where the UE is located.

[0045] However, third-party positioning platforms are limited to positioning in scenarios where corresponding positioning devices are deployed, and there is a problem of small positioning range.

[0046] In view of the problems existing in the outdoor intensive positioning platform and the third-party positioning platform, the embodiments of the present disclosure provide a positioning method, which converges the positioning capabilities of different third-party positioning platforms by introducing intermediate network devices. Without changing the outdoor intensive positioning platform, the switching of indoor and outdoor positioning capabilities is achieved through the SUPL protocol, so that during the positioning process of the UE, when the UE is in an outdoor environment, the outdoor intensive positioning platform uses 5G positioning or satellite positioning to provide positioning services for the UE, and when the UE is in an indoor environment, the outdoor intensive positioning platform and the third-party positioning platform work together to provide the UE with high-precision indoor positioning services.

[0060] like Figure 1 As shown, the positioning system architecture may include: UE 101 , H-SLP 102 , intermediate network device 103 and third-party positioning platform 104 .

[0061] Among them, UE 101 is a user equipment with SUPL capability, and an application corresponding to the third-party positioning platform 104 is installed in UE 101, through which the third-party positioning platform 104 can obtain data for locating the UE 101. It should be noted that before the third-party positioning platform 104 obtains the data through the application, the owner of UE 101 needs to perform corresponding authorization.

[0062] H-SLP 102 may interact with UE 101 via standard SUPL protocol.

[0063] The intermediate network device 103 can aggregate and converge the positioning information of the third-party positioning platform, convert it into information recognizable by the H-SLP, and then send it to the H-SLP through the RLP protocol.

[0064] The third-party positioning platform 104 can be obtained by adding an interface for interacting with the intermediate network device 103 to the original third-party positioning platform, and the third-party positioning platform 104 can interact with the H-SLP 102 through the intermediate network device 103. Among them, the interface can be customized or defined based on the standard MLP (Mobile Location Protocol) protocol.

[0065] The UE 101, the H-SLP 102, the intermediate network device 103 and the third-party positioning platform 104 are connected to each other through a network, which may be a wired network or a wireless network.

[0066] Optionally, the wireless network or wired network described above uses standard communication technology and / or protocol. The network is usually the Internet, but it can also be any network, including but not limited to a local area network (LAN), a metropolitan area network (MAN), a wide area network (WAN), a mobile, wired or wireless network, a dedicated network or any combination of a virtual private network).

Among them, SLC is used to coordinate SUPL operations in the network, implement interaction with UE, and interact with third-party positioning platforms through standard SUPL protocols without adding additional capabilities. SPC is an entity in the SUPL network that processes request positioning calculations and delivers auxiliary data messages.

[0069] The intermediate network device 103 may be a server with the above capabilities.

[0070] The third-party positioning platform 104 may be composed of at least one third-party server having the above functions.

[0071] Those skilled in the art will know that Figure 1 The number of UE 101 and third-party positioning platform 104 is only for illustration, and any number of UE 101 and third-party positioning platform 104 may be provided according to actual needs. The embodiments of the present disclosure are not limited to this.

[0072] The present exemplary implementation is described in detail below with reference to the accompanying drawings and embodiments.

[0073] A positioning method is provided in an embodiment of the present disclosure. The method can be executed by any electronic device with computing and processing capabilities.

[0074] Figure 2 A flow chart of a positioning method in an embodiment of the present disclosure is shown as follows: Figure 2 As shown, the positioning method provided in the embodiment of the present disclosure includes the following steps S201 to S210.

[0075] S201: H-SLP receives first location information sent by UE through a SUPL session.

[0076] In some embodiments, before the H-SLP receives the first location information sent by the UE through the SUPL session, it is necessary to first establish a SUPL session between the UE and the H-SLP. The SUPL session can be initiated by the UE, or other network devices can request the H-SLP to locate the UE. After receiving the request, the H-SLP initiates a SUPL session to the UE. Through the SUPL session between the UE and the H-SLP, the UE can send the location information to the H-SLP. For example, the UE sends the first location information to the H-SLP through the SUPL session.

[0077] S202, the H-SLP determines an intermediate network device corresponding to the first location information.

[0078] In some embodiments, a second electronic fence is provided in the H-SLP, and the second electronic fence is used to limit the UE's position to trigger subsequent operations after reaching the target area. For example, the target area is the area corresponding to the A shopping mall. After the UE's position moves from a certain position away from the A shopping mall to the A shopping mall and reaches the A shopping mall area defined by the second electronic fence, the second electronic fence is triggered. After the second electronic fence is triggered, the H-SLP can perform preset post-trigger operations. In some embodiments, the H-SLP determines the intermediate network device corresponding to the first location information, which may include: determining the intermediate network device corresponding to the first location information when the first location information triggers the second electronic fence.

[0079] In some embodiments, different regions correspond to different intermediate network devices. For example, region 1 corresponds to intermediate network device 1, and region 2 corresponds to intermediate network device 2. In some embodiments, the intermediate network device corresponding to a region is used to serve the region. In other embodiments, when the intermediate network device corresponding to the current region fails, the current region can be served by requesting the intermediate network device of the adjacent region.

[0080] The H-SLP can determine the intermediate network device serving the region according to the region where the UE is located indicated by the first location information. For example, if the first location information indicates that the region where the UE is located is region 1, and intermediate network device 1 serves region 1, then the intermediate network device determined according to the first location information is intermediate network device 1.

[0081] S203, H-SLP sends an RLP SSRLIR message to the intermediate network device, where the RLP SSRLIR message carries the first location information and the UE's mobile station identifier MSID, so that the intermediate network device can determine the corresponding third-party positioning platform and positioning method according to the first location information, and obtain the UE's positioning result from the third-party positioning platform according to the MSID.

[0082] Among them, the intermediate network device is configured with the RLP protocol and can interact with the H-SLP based on the RLP protocol. After the H-SLP determines the corresponding intermediate network device according to the first location information, it generates a RLP SSRLIR message according to the first location information and the MSID of the UE, and sends the RLP SSRLIR message to the intermediate network device. Then, S204 is performed.

[0083] S204, the intermediate network device receives a RLP SSRLIR message sent by a home location positioning platform H-SLP corresponding to the user equipment UE, where the RLP SSRLIR message carries the first location information of the UE and a mobile station identifier MSID.

[0084] After receiving the RLP SSRLIR message, the intermediate network device parses the RLP SSRLIR message to obtain the first location information and the MSID identifier.

[0085] S205: The intermediate network device determines a third-party positioning platform and a positioning method corresponding to the first location information.

[0086] Among them, a connection relationship is established between the intermediate network device and different third-party positioning platforms. For example, the connection relationship can be achieved by adding a new interface in the third-party positioning platform, and the intermediate network device can achieve information exchange with the third-party positioning platform through the new interface. The new interface in the third-party positioning platform can be a custom interface or an interface defined based on the standard MLP protocol, which is not limited in the embodiments of the present disclosure.

[0087] In some embodiments, different third-party positioning platforms have positioning capabilities within different ranges. For example, third-party positioning platform A deploys corresponding positioning devices / equipment in indoor scene 1 and indoor scene 2, so that third-party positioning platform A can locate UEs in indoor scene 1 and indoor scene 2. For another example, third-party positioning platform B deploys corresponding positioning devices / equipment in shopping mall A and shopping mall B, so that third-party positioning platform B can locate UEs in shopping mall A and shopping mall B. When the first location information indicates that the location of the UE is located in shopping mall A or within the threshold range of shopping mall A, the third-party positioning platform determined by the intermediate network device based on the first location information is a third-party positioning platform that can locate the UE in shopping mall A. In some embodiments, there are multiple third-party positioning platforms that can locate the area corresponding to the first location information. At this time, the third-party positioning platform determined based on the first location information can be any one of the multiple third-party positioning platforms.

[0088] In another embodiment, there are multiple third-party positioning platforms that can locate the area corresponding to the first location information. At this time, the third-party positioning platform determined based on the first location information can be the third-party positioning platform with the highest positioning accuracy among the multiple third-party positioning platforms. In some embodiments, the positioning accuracy of the UE of the third-party positioning platform at the scene corresponding to the first location information can be pre-stored in the intermediate network device, and the accuracy request message corresponding to the first location information can be sent to the multiple third-party positioning platforms, and the positioning accuracy of the multiple third-party positioning platforms at the scene corresponding to the first location information is determined based on the messages fed back by the multiple third-party positioning platforms.

[0089] In some embodiments, the third-party positioning platform realizes the positioning of the UE in different ranges according to the corresponding positioning methods. For example, the third-party positioning platform A realizes the positioning of the UE based on the Bluetooth fingerprint in indoor scene 1, realizes the positioning of the UE based on the WIFI fingerprint in indoor scene 2, and realizes the positioning of the UE based on both the WIFI fingerprint and the Bluetooth fingerprint in indoor scene 3. Therefore, the corresponding positioning method can also be determined according to the first location information.

[0090] S206: The intermediate network device sends an RLP SSRLIA message to the H-SLP to complete the establishment of the RLP session with the H-SLP.

[0091] In some embodiments, the RLP SSRLIR message sent by the H-SLP to the intermediate network device includes SUPLTRIGGERED START. After the intermediate network device determines the positioning method according to the first location information, it generates an RLP SSRLIA message that feeds back the RLP SSRLIR message according to the positioning method, and the RLP SSRLIA message includes SUPL TRIGGEREDRESPONSE. The SUPL TRIGGERED RESPONSE carries the positioning method determined according to the first location information and a session identifier that identifies the SUPL session between the UE and the H-SLP.

[0092] Afterwards, the intermediate network device sends an RLP SSRLIA message to the H-SLP, thereby establishing an RLP session with the H-SLP.

[0093] S207, the H-SLP receives the RLP SSRLIA message sent by the intermediate network device, and completes the establishment of the RLP session with the intermediate network device.

[0094] In some embodiments, after receiving the RLP SSRLIA message sent by the intermediate network device, the H-SLP parses the RLPSSRLIA message to obtain a SUPL TRIGGERED RESPONSE, and forwards the SUPL TRIGGERED RESPONSE to the UE, so that the UE updates the SUPL session indicated by the identifier included in the SUPL TRIGGERED RESPONSE according to the positioning method included in the SUPL TRIGGERED RESPONSE, that is, the UE updates the SUPL session between the UE and the H-SLP according to the positioning method.

[0095] S208: The intermediate network device sends a positioning request carrying the MSID to the third-party positioning platform, so that the third-party positioning platform can locate the UE indicated by the MSID according to the positioning method.

[0096] The intermediate network device generates a positioning request according to the MSID, and sends the positioning request to the third-party positioning platform determined according to the first location information. After receiving the positioning request, the third-party positioning platform locates the UE indicated by the MSID included in the positioning request, and feeds back the positioning result to the intermediate network device. The embodiments of the present disclosure do not limit how the third-party positioning platform locates the UE. For example, an application corresponding to the third-party positioning platform is installed in the UE. With the authorization of the owner corresponding to the UE, the third-party positioning platform can obtain data for locating the UE from the UE according to the application, and then locate the UE according to the positioning data to obtain the positioning result.

[0097] For example, a third-party positioning platform positions the UE, obtains a first positioning result, and sends the first positioning result to an intermediate network device.

[0098] S209: The intermediate network device receives the first positioning result sent by the third-party positioning platform, and sends the first positioning result to the H-SLP according to the RLP session, so that the H-SLP determines the position of the UE according to the first positioning result.

[0099] S210, the H-SLP receives a positioning result sent by the intermediate network device according to the RLP session, and determines the position of the UE according to the positioning result.

[0100] In some embodiments, the H-SLP receives the positioning result sent by the intermediate network device according to the RLP session, and before determining the location of the UE according to the positioning result, the map data of the third-party positioning platform has been synchronized. Determining the location of the UE according to the positioning result may include: determining the location of the UE according to the positioning result and the map data. It should be noted that the positioning result may be the first positioning result.

[0101] According to the technical solution provided by the embodiments of the present disclosure, the intermediate network device establishes an RLP session with the H-SLP corresponding to the UE through the process specified by the RLP protocol. The first location information of the UE received during the establishment of the RLP session is used to determine the corresponding third-party positioning platform and positioning method, and the received MSID of the UE is sent to the third-party positioning platform. The third-party positioning platform locates the UE indicated by the MSID, and feeds back the positioning result to the intermediate network device, which then sends the positioning result to the H-SLP according to the RLP session. By connecting the H-SLP and the third-party positioning platform using the intermediate network device, the third-party positioning platform can be connected without modifying the outdoor intensive positioning platform (H-SLP), thereby utilizing the indoor positioning capability of the third-party platform to assist the outdoor intensive positioning platform in locating the UE, thereby achieving high-precision positioning services for the UE in both indoor and outdoor environments.

[0102] Figure 3 A flowchart of a positioning method in another embodiment of the present disclosure is shown. In some embodiments, Figure 2 S210 of the corresponding embodiment also includes S301 to S304.

[0103] S301, H-SLP sends a first positioning result to UE.

[0104] After receiving the first positioning result, the H-SLP forwards the first positioning result to the UE.

[0105] S302: After obtaining the first positioning result, the third-party positioning platform re-positions the UE at intervals of a reference time to obtain a second positioning result, and sends the second positioning result obtained from each positioning to the intermediate network device.

[0106] S303: The intermediate network device receives the second positioning result sent by the third-party positioning platform, and sends the second positioning result to the H-SLP through the RLP session.

[0107] S304, the H-SLP receives the second positioning result forwarded by the intermediate network device, and sends the second positioning result to the UE through the SUPL session.

[0108] The present disclosure is a technical solution provided by an embodiment. After the H-SLP establishes a session with an intermediate network device and the session is maintained, the H-SLP can continuously receive positioning results for the UE from the intermediate network device, thereby achieving continuous high-precision positioning of the UE in an indoor environment.

[0109] In some embodiments, when the UE switches from an indoor environment to an outdoor environment, the UE also correspondingly switches from positioning based on a third-party positioning platform to positioning based on an outdoor intensive positioning platform. Figure 4 A flow chart of a positioning method in another embodiment of the present disclosure is shown, including S401 to S406.

[0110] S401, the intermediate network device receives a positioning switching message sent when a positioning result of a third-party positioning platform on the UE indicates that the UE triggers a first electronic fence, and the positioning switching message includes second location information when the UE triggers the first electronic fence.

[0111] In some embodiments, a first electronic fence is provided in the intermediate network device, and the first electronic fence is used to limit the UE's position to trigger subsequent operations after leaving the target area. For example, the target area is the area corresponding to the A shopping mall. After the UE's position leaves the A shopping mall, moves in the direction of the A shopping mall and reaches the A shopping mall area defined by the first electronic fence, the first electronic fence is triggered. After the first electronic fence is triggered, the third-party positioning platform can perform the preset post-trigger operation.

[0112] In one embodiment, when the positioning result of the third-party positioning platform for the UE indicates that the UE triggers the first electronic fence, the third-party positioning platform sends a positioning switching message to the intermediate network device, and the positioning switching message carries the second location information when the UE triggers the first electronic fence.

[0113] S402, the intermediate network device sends an RLP SRLIR message carrying the MSID and the second location information to the H-SLP, so that the H-SLP updates the secure user plane SUPL session between the H-SLP and the UE according to the MSID and the second location information, so that the UE sends a third positioning result to the H-SLP through the updated SUPL session.

[0114] In some embodiments, after receiving the location switching message, the intermediate network device parses the location switching message to obtain the second location information. Thereafter, the intermediate network device generates an RLP SRLIR message according to the second location information, and the RLP SRLIR message carries the second location information and the MSID of the UE.

[0115] S403, the H-SLP receives an RLP SRLIR message sent by the intermediate network device and carrying the MSID and the second location information.

[0116] S404: The H-SLP determines the location of the UE according to the second location information and the map data.

[0117] After receiving the RLP SRLIR message, the H-SLP parses the RLP SRLIR message to obtain the second location information, and then determines the location of the UE according to the second location information and the map data pre-synchronized from the third-party positioning platform.

[0118] S405, the H-SLP sends a SUPL INIT message to the UE indicated by the MSID.

[0119] In some embodiments, after receiving the RLP SRLIR message, the H-SLP generates a SUPL INIT message for initializing a SUPL session according to an instruction of the RLP SRLIR message, and sends the SUPL INIT message to the UE indicated by the MSID carried in the RLP SRLIR message. After receiving the SUPL INIT message, the UE updates the SUPL session between the UE and the H-SLP according to an instruction of the SUPL INIT message, and generates a SUPL POSINIT message for feeding back the SUPL INIT message after the update. Thereafter, the SUPL POS INIT message is sent to the H-SLP.

[0120] S406, the H-SLP receives the SUPL POS INIT message fed back by the UE in response to the SUPL INIT message, and determines that the SUPL session between the H-SLP and the UE is updated, so that the UE sends a third positioning result to the H-SLP based on the updated SUPL session.

[0121] The technical solution provided by the embodiment of the present disclosure realizes the problem of positioning service coordination between the outdoor intensive positioning platform and the third-party positioning platform by adding intermediate network equipment, so that the UE can enjoy high-precision positioning services in both indoor and outdoor environments.

[0122] To facilitate understanding of the technical solutions provided by the embodiments of the present disclosure, Figure 2 , Figure 3 The corresponding embodiment is used to illustrate the switching process of the positioning mode from the outdoor environment to the indoor environment.
