[0004] However, a complete solution to achieve coverage and switching between indoor and outdoor mixed scenarios is costly and difficult to implement. Summary of the Invention

[0005] This application provides a positioning method, device, server, and storage medium to solve the problems of high cost and difficulty in construction for achieving coverage and switching in mixed indoor and outdoor scenarios.

[0006] Firstly, this application provides a positioning method, including:

[0007] Obtain the first identifier of the primary serving cell to which the device to be located belongs, and obtain the identifier list of the measurement cells corresponding to the primary serving cell, wherein the identifier list includes the second identifier of the measurement cells;

[0008] Based on the first identifier of the primary serving cell and the second identifier of the measuring cell in the identifier list, the area type of the device to be located is determined, wherein the area type includes a pre-calibrated outdoor area, an indoor-outdoor transition area, and an indoor area.

[0009] If the area type is an outdoor area, then the satellite positioning data of the device to be positioned will be used as the real-time positioning data of the device to be positioned.

[0010] If the area type is an indoor-outdoor transition area, then the 5G positioning data of the device to be located will be used as the real-time positioning data of the device to be located.

[0011] If the area type is an indoor area, then the 5G positioning data or preset indoor positioning data shall be used as the real-time positioning data of the device to be positioned.

[0013] In one possible design, determining the area type of the device to be located based on the first identifier of the primary serving cell and the second identifier of the measuring cells in the identifier list includes:

[0014] If the first identifier belongs to a pre-calibrated outdoor area cell, and the second identifiers of all measurement cells in the identifier list belong to pre-calibrated outdoor area cells, then the area type of the device to be located is determined to be an outdoor area.

[0015] If the first identifier belongs to a pre-calibrated indoor-outdoor transition zone cell, and the second identifier of the measurement cell in the identifier list belongs to a pre-calibrated outdoor area, indoor-outdoor transition zone, and indoor area, then the area type of the device to be located is determined to be an indoor-outdoor transition zone.

[0020] If the average field strength of the n measurement cycles satisfies the first preset condition; and the second identifier of all measurement cells in the identifier list of the measurement cells corresponding to the primary serving cell satisfies the second preset condition, or the average field strength of any measurement cycle among the n measurement cycles satisfies the third preset condition, then the satellite positioning data is switched to be used as the real-time positioning data of the device to be positioned.

[0021] In one possible design, determining that the average field strength of the n measurement cycles satisfies a first preset condition includes:

[0025] Then it is determined that the average field strength of the n measurement cycles meets the first preset condition.

[0026] In one possible design, the second preset condition includes: the second identifier of all measurement cells in the identifier list of the measurement cells corresponding to the main serving cell does not belong to the pre-calibrated indoor area.

[0027] In one possible design, the third preset condition includes: the average field strength of any one of the n measurement cycles is less than the second threshold.

[0046] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] With the development of IoT technology, human demand for location information services is increasing. Location information services provide navigation and positioning functions, including both outdoor and indoor navigation and positioning. However, as the location service field continues to evolve, it is no longer limited to single indoor or outdoor scenarios; the demand for mixed indoor and outdoor scenarios has become one of the current research hotspots in location services. Currently, mixed indoor and outdoor scenarios often employ a complete solution encompassing hardware, platform, and algorithms to achieve coverage and switching between these scenarios. However, such solutions are often complex to implement and costly.

[0048] To address the aforementioned technical problems, this application proposes the following technical approach: Considering that the indoor-outdoor transition zone is the area where indoor and outdoor areas meet, satellite positioning data from the outdoor area and 5G positioning data or other indoor positioning data from the indoor area can be used to locate the device to be positioned in the indoor-outdoor transition zone. The location of the object being located is determined by the first identifier of the primary serving cell and the identifier list of the corresponding measurement cells. Different positioning technologies and location data are used for different areas, achieving positioning in mixed indoor-outdoor scenarios with lower cost and difficulty. Detailed embodiments are described below.

[0049] Figure 1 This is a schematic diagram illustrating an application scenario of the positioning method provided in the embodiments of this application. For example... Figure 1 As shown, it includes: server 101, main service cell 102 and device to be located 103.

[0050] The device to be located 103 sends a location positioning request to the server 101. The server 101 measures the signal of the serving cells around the device to be located 103, determines the serving cell with the strongest signal among the serving cells occupied by the device to be located 103 as the main serving cell 102, and obtains the first identifier of the main serving cell 102 and the identifier list of the measurement cells corresponding to the main serving cell 102. The server 101 performs real-time positioning of the device to be located 103 according to the first identifier of the main serving cell 102 and the second identifier in the identifier list of the measurement cells corresponding to the main serving cell 102.

[0051] Figure 2Flowchart of the positioning method provided in the embodiments of this application Figure 1 The execution entity in this embodiment can be Figure 1 The server in the illustrated embodiment is not specifically limited in this embodiment. Figure 2 The method includes:

[0052] S201: Obtain the first identifier of the primary serving cell to which the device to be located belongs, and obtain the identifier list of the measurement cells corresponding to the primary serving cell, wherein the identifier list includes the second identifier of the measurement cells.

[0053] The primary serving cell is the cell associated with the radio access node that provides control plane connectivity to the core network. It is the cell used to initiate initial access and has the strongest signal among the serving cells occupied by the device to be located. Multiple measurement cells are defined within a primary serving cell based on differences in carrier frequency and scrambling code. The identifier list of measurement cells corresponding to the primary serving cell includes secondary identifiers for multiple measurement cells, used to indicate the area where the cell is located.

[0054] Specifically, the server receives a location request from the device to be located and identifies the serving cell with the strongest signal among the serving cells occupied by the device as the primary serving cell. Within a preset range of the primary serving cell, different preset areas are divided according to different carrier frequencies and scrambling codes, and each preset area is identified as a measurement cell. The server obtains the first identifier of the primary serving cell and the second identifiers of all measurement cells in the identifier list corresponding to the primary serving cell.

[0055] S202: Based on the first identifier of the primary serving cell and the second identifier of the measuring cell in the identifier list, determine the area type of the device to be located, where the area type includes pre-calibrated outdoor area, indoor-outdoor transition area and indoor area.

[0056] In this embodiment, cells within a defined range that have the following significant characteristics are designated as indoor-outdoor transition areas: simultaneously meeting the performance requirements of satellite positioning and 5G NR positioning.

[0057] For example, designating a cell as an outdoor area can be done by marking the cell as "ID-A"; designating a cell as an indoor-outdoor transition area can be done by marking the cell as "ID-B"; and designating a cell as an indoor area can be done by marking the cell as "ID-C".

[0058] Specifically, step S202 includes Sa to Sc:

[0059] Sa: If the first identifier belongs to a pre-calibrated outdoor area cell, and the second identifiers of all measurement cells in the identifier list belong to pre-calibrated outdoor area cells, then the area type of the device to be located is determined to be an outdoor area.

[0060] For example, if the first identifier of the primary serving cell is "ID-A" and the second identifier of all the measurement cells in the identifier list is "ID-A", then the area type of the device to be located is determined to be an outdoor area.

[0061] Sb: If the first identifier belongs to a pre-calibrated indoor-outdoor transition zone cell, and the second identifier of the measurement cell in the identifier list belongs to a pre-calibrated outdoor area, indoor-outdoor transition zone, and indoor area, then the area type of the device to be located is determined to be an indoor-outdoor transition zone.

[0062] For example, if the first identifier of the primary serving cell is "ID-B", and the second identifiers of all measurement cells in the identifier list include "ID-A", "ID-B", and "ID-C", then the area type of the device to be located is determined to be an indoor-outdoor transition area.

[0063] Sc: If the first identifier belongs to a pre-calibrated indoor area cell, and the second identifiers of all measurement cells in the identifier list belong to pre-calibrated indoor area cells, then the area type of the device to be located is determined to be an indoor area.

[0064] For example, if the first identifier of the primary serving cell is "ID-C" and the second identifier of all the measuring cells in the identifier list is "ID-C", then the area type of the device to be located is determined to be an outdoor area.

[0065] S203: If the area type is an outdoor area, then the satellite positioning data of the device to be positioned shall be used as the real-time positioning data of the device to be positioned.

[0066] The device to be located is bound to both a satellite positioning terminal and a 5G positioning terminal, or to a multi-mode terminal that simultaneously supports satellite positioning and 5G positioning. The satellite positioning data of the device to be located comes from either the satellite positioning terminal or the multi-mode terminal.

[0067] Specifically, if the area type is an outdoor area, the device to be located will continuously measure satellite positioning signals through a satellite positioning terminal or a multi-mode terminal to obtain location positioning data, and the satellite positioning data of the device to be located will be used as the real-time positioning data of the device to be located.

[0068] S204: If the area type is an indoor-outdoor transition area, then the 5G positioning data of the device to be located will be used as the real-time positioning data of the device to be located.

[0069] The device to be located is bound to both a satellite positioning terminal and a 5G positioning terminal, or to a multi-mode terminal that simultaneously supports satellite positioning and 5G positioning. The 5G positioning data of the device to be located comes from the 5G positioning terminal or the multi-mode terminal.

[0070] Specifically, if the area type is an indoor-outdoor transition area, the device to be located will continuously measure the 5G positioning signal through a 5G positioning terminal or a multi-mode terminal to obtain location positioning data, and the 5G positioning data of the device to be located will be used as the real-time positioning data of the device to be located.

[0071] S205: If the area type is an indoor area, then the real-time positioning data of the device to be positioned shall be based on 5G positioning data or preset indoor positioning data.

[0072] The device to be located is bound to both a satellite positioning terminal and a 5G positioning terminal, or to a multi-mode terminal that simultaneously supports satellite positioning and 5G positioning. The 5G positioning data of the device to be located comes from the 5G positioning terminal or the multi-mode terminal. The preset indoor positioning data comes from preset indoor positioning technologies, which can be WiFi, Bluetooth, UWB (UltraWide Band), and cellular mobile network technologies.

[0073] Specifically, if the area type is an indoor-outdoor transition zone, the device to be located will continuously measure the 5G positioning signal through a 5G positioning terminal or a multi-mode terminal to obtain location data, and use the 5G positioning data of the device to be located as the real-time positioning data of the device to be located. Alternatively, location data can be obtained based on preset indoor positioning technologies used in the indoor area, such as WiFi, Bluetooth, UWB, and cellular mobile network technologies, and the preset indoor positioning data can be used as the real-time positioning data of the device to be located.

[0074] S206: Real-time positioning of the object to be positioned is performed based on the real-time positioning data of the device to be positioned.

[0075] The object being located is either a person holding the device to be located, or an object on which the device is installed.

[0076] Specifically, if the area where the object to be located is located is an outdoor area, the object is located in real time based on the real-time positioning data of the device to be located, and a wide-area map is used for the geographical representation of the object. If the area where the object is located is an indoor-outdoor transition area, the object is located in real time based on the real-time positioning data of the device to be located, and a customized map is used for the geographical representation of the object. If the area where the object is located is located is an indoor area, the object is located in real time based on the real-time positioning data of the device to be located, and a customized indoor map is used for the geographical representation of the object.

[0077] In summary, the area described by the device to be located is determined by the first identifier of the main service cell occupied by the outdoor area, the indoor-outdoor transition area, and the indoor area, and the second identifier of all the measurement cells in the identifier list of the measurement cells corresponding to the main service cell. Based on this, real-time positioning data of different positioning technologies are selected, and the object to be located is located in real time according to the real-time positioning data of the device to be located. This achieves positioning of mixed indoor and outdoor scenes with low cost and difficulty.

[0078] Figure 3 Flowchart of the positioning method provided in the embodiments of this application Figure 2 In the embodiments of this application, in Figure 2 Based on the provided embodiments, the specific implementation method for switching the positioning device from 5G positioning data to satellite positioning data after step S204 is described in detail. For example... Figure 3 As shown, the method includes:

[0079] S301: Continuously collect multiple field strength information of the primary serving cell in each measurement cycle, and calculate the average field strength of each measurement cycle based on the multiple field strength information.

[0080] Specifically, each measurement cycle can collect m field strength data points, denoted as E1, E2, ..., E m The formula for calculating the average field strength for each measurement cycle based on multiple field strength data is as follows:

[0081]

[0082] In the formula, Let E1, E2, ..., E be the average field strength during the i-th measurement period, where i is a positive integer. m This represents m field strength data points collected within one measurement cycle, where m is a positive integer.

[0083] For example, the duration of a measurement cycle can be 1 second, 10 seconds, or 60 seconds.

[0084] S302: When the average field strength of any measurement cycle is found to be less than the first threshold, record the average field strength of n consecutive measurement cycles after any measurement cycle, where n is a positive integer.

[0085] Specifically, when it is detected that the average field strength of any measurement period, calculated based on the field strength information collected within any measurement period, is less than the first threshold, another event is triggered: field strength information is collected for n consecutive measurement periods, and the average field strength of the n consecutive measurement periods is calculated based on the field strength information collected for the n consecutive measurement periods, and the average field strength of the n consecutive measurement periods is recorded, where n is a positive integer.

[0086] For example, when the average field strength of any measurement cycle is found to be less than a first threshold, the average field strength of the next n consecutive measurement cycles is recorded, respectively. Where n is a positive integer.

[0087] S303: If the average field strength of n measurement cycles meets the first preset condition; and the second identifier of all measurement cells in the identifier list of the measurement cell corresponding to the main serving cell meets the second preset condition or the average field strength of any measurement cycle in the n measurement cycles meets the third preset condition, then switch to using satellite positioning data as the real-time positioning data of the device to be positioned.

[0088] Specifically, step S303, determining that the average field strength over n measurement cycles meets the first preset condition, includes:

[0089] If the average field strength over n measurement periods satisfies the following formula:

[0090]

[0091] In the formula, To record the average field strength of the first measurement cycle after the average field strength of any measurement cycle is found to be less than the first threshold; To record the average field strength of the second measurement period after the average field strength of any measurement period is less than the first threshold; To detect that the average field strength of any measurement period is less than the first threshold, the average field strength of the nth measurement period is recorded, where n is a positive integer.

[0092] If the average field strength over n measurement cycles meets the first preset condition, and if the second identifier of all measurement cells in the identifier list corresponding to the primary serving cell does not belong to the pre-calibrated indoor area, or if the average field strength over any measurement cycle is less than the second threshold, then the 5G positioning data will be switched to satellite positioning data, and the satellite positioning data will be used as the real-time positioning data of the device to be positioned.

[0093] In summary, by calculating the average field strength of each measurement cycle, it can be determined whether the conditions are met to switch from 5G positioning data to satellite positioning data, and then use the satellite positioning data as the real-time positioning data of the device to be positioned. This achieves the switching of positioning technology in indoor-outdoor transition areas at a lower cost and with less difficulty.

[0094] Figure 4 This is a schematic diagram of the positioning device provided in an embodiment of this application. Figure 5As shown, the positioning device includes: an identifier acquisition module 401, an area judgment module 402, an outdoor area positioning module 403, a transition area positioning module 404, an indoor area positioning module 405, and a real-time positioning module 406.

[0095] The identifier acquisition module 401 is used to acquire the first identifier of the primary serving cell to which the device to be located belongs, and to acquire the identifier list of the measurement cells corresponding to the primary serving cell, wherein the identifier list includes the second identifier of the measurement cells.

[0096] The area determination module 402 is used to determine the area type of the device to be located based on the first identifier of the main serving cell and the second identifier of the measuring cell in the identifier list. The area type includes pre-calibrated outdoor area, indoor-outdoor transition area and indoor area.

[0097] The outdoor area positioning module 403 is used to use the satellite positioning data of the device to be positioned as the real-time positioning data of the device to be positioned if the area type is an outdoor area.

[0098] The transition area positioning module 404 is used to use the 5G positioning data of the device to be positioned as the real-time positioning data of the device to be positioned if the area type is an indoor-outdoor transition area.

[0099] The indoor area positioning module 405 is used to use 5G positioning data or preset indoor positioning data as the real-time positioning data of the device to be positioned if the area type is an indoor area.

[0100] The real-time positioning module 406 is used to locate the object being located in real time based on the real-time positioning data of the device to be located.

[0101] In one possible implementation, the area determination module 402 is specifically configured to determine the area type of the device to be located as an outdoor area if the first identifier belongs to a pre-calibrated outdoor area cell and the second identifiers of all measurement cells in the identifier list belong to pre-calibrated outdoor area cells. If the first identifier belongs to a pre-calibrated indoor-outdoor transition area cell and the second identifiers of the measurement cells in the identifier list belong to a pre-calibrated outdoor area, indoor-outdoor transition area, and indoor area, then the area type of the device to be located is determined to be an indoor-outdoor transition area. If the first identifier belongs to a pre-calibrated indoor area cell and the second identifiers of all measurement cells in the identifier list belong to pre-calibrated indoor area cells, then the area type of the device to be located is determined to be an indoor area.

[0102] In one possible implementation, the positioning device further includes a switching module, which is specifically used to continuously collect multiple field strength information from the primary serving cell in each measurement cycle, and calculate the average field strength for each measurement cycle based on the multiple field strength information. When the average field strength for any measurement cycle is detected to be less than a first threshold, the average field strength for n consecutive measurement cycles following that measurement cycle is recorded, where n is a positive integer. If it is determined that the average field strength for n measurement cycles meets a first preset condition; and the second identifiers of all measurement cells in the identifier list of the measurement cells corresponding to the primary serving cell meet a second preset condition, or the average field strength for any one of the n measurement cycles meets a third preset condition, then the device switches to using satellite positioning data as the real-time positioning data for the device to be positioned.

[0103] In one possible implementation, the positioning device further includes a first preset condition determination module, which is specifically used to determine if the average field strength of n measurement cycles satisfies the following formula:

[0104]

[0105] In the formula, To record the average field strength of the first measurement cycle after the average field strength of any measurement cycle is found to be less than the first threshold; To record the average field strength of the second measurement period after the average field strength of any measurement period is less than the first threshold; To detect that the average field strength of any measurement cycle is less than a first threshold, the average field strength of the nth measurement cycle is recorded. Then, it is determined that the average field strength of the nth measurement cycle satisfies a first preset condition.
