Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to an indoor positioning method, apparatus and related equipment. Background Technology

[0002] For indoor positioning, fingerprint positioning is an important method because it has the advantages of high accuracy, independence from data collection and processing within the operator's network, and rapid deployment.

[0003] The fingerprint positioning method itself also relies on triangulation technology, which often requires more than three cells. However, the number of base station cells deployed is generally determined based on coverage and capacity targets. Especially indoors, multiple antennas typically transmit signals from one cell, resulting in an insufficient number of cells required for fingerprint positioning, which in turn affects positioning accuracy.

[0034] Those skilled in the art will know that Figure 1 The number of terminals, networks, and network-side devices shown is merely illustrative; any number of terminals, networks, and network-side devices can be included as needed. This disclosure does not limit the scope of the embodiments.

[0035] Under the above system architecture, this disclosure provides an indoor positioning method that can be executed by any electronic device with computing power.

[0036] In some embodiments, the indoor positioning method provided in this disclosure can be executed by a terminal device in the above-described system architecture; in other embodiments, the indoor positioning method provided in this disclosure can be executed by a server in the above-described system architecture; in still other embodiments, the indoor positioning method provided in this disclosure can be implemented by the terminal device and the server in the above-described system architecture through interaction.

[0037] Figure 2 This diagram illustrates an indoor positioning method according to an embodiment of the present disclosure. The method includes the following steps:

[0038] S202, Obtain cell information of multiple cells in the target area, wherein the cell information includes the signal strength of each cell, the target area includes multiple antenna systems, and one cell corresponds to multiple antenna systems.

[0039] It should be noted that the target area in this embodiment can be any geographical location or a certain range that needs to be located. It can be a completely enclosed room or an open playground. For example, the target area can be a shopping mall. In this embodiment, a cell is a basic geographic service unit of a mobile communication network, which is covered and served by a base station. However, there may be multiple cells in the target area, which are covered by multiple base stations. This means that the signal strength of some locations in the target area may be interfered with by multiple signals. In addition, the antenna system in this embodiment refers to a device composed of one or more antennas and their related components, used to transmit and receive radio signals.

[0040] S204, delete cells whose transmitted cell signal strength is less than a preset threshold under the same antenna system, and obtain the first cell information in the target area.

[0041] It should be noted that the signal strength of cells transmitted under the same antenna system may indeed vary. These differences are determined by the configuration of the antenna system, environmental conditions, and specific mechanisms in the communication protocol. Therefore, by eliminating weak coverage cells at the same antenna transmission point, this embodiment of the present disclosure can resist and reduce the problem of large fluctuations in weak signals affecting positioning accuracy, thereby improving positioning accuracy. Furthermore, the preset threshold in this embodiment of the present disclosure can be set according to the actual situation. For example, this embodiment of the present disclosure can set the preset threshold to -105dBm. -105dBm usually represents a very weak signal. Of course, the preset threshold in this embodiment of the present disclosure is not limited to -105dBm. This embodiment of the present disclosure does not impose a point limitation on the preset threshold.

[0042] S206, sort the signal strengths of multiple cells in the first cell information, control the number of cells in the target area to be less than a preset threshold, and obtain the second cell information in the target area.

[0043] It should be noted that in this embodiment of the present disclosure, the signal strength of multiple cells in the first cell information can be sorted in descending order or in ascending order, and cells with lower signal strength in the sequence can be deleted. For example, in this embodiment of the present disclosure, by deleting cells with lower signal strength, the number of cells can be maintained within a certain range. The preset threshold in this embodiment of the present disclosure can be set to 8, and only 7 cells with higher signal strength can be retained. This can ensure positioning accuracy, reduce the amount of computation and time consumption caused by too many cells, and improve positioning efficiency.

[0044] S208, Match and locate the user in the target area by matching the signal strength of the user equipment's location in the second cell information with the signal strength recorded in the pre-established fingerprint database. The fingerprint database contains the coordinate information of each location in the target area and the corresponding signal strength.

[0045] The indoor positioning method provided in the embodiments of this disclosure firstly acquires cell information of multiple cells within a target area, wherein the cell information includes the signal strength of each cell, and one cell within the target area corresponds to multiple antenna systems; secondly, cells whose transmitted signal strength under the same antenna system is less than a preset threshold are deleted to obtain first cell information within the target area; then, the signal strengths of multiple cells in the first cell information are sorted to control the number of cells in the target area to be less than a preset threshold to obtain second cell information within the target area; finally, the signal strength at the location of the user equipment in the second cell information is matched with the signal strength recorded in a pre-established fingerprint database to achieve indoor positioning of the user within the target area. Compared to fingerprint positioning methods used in related technologies for indoor positioning, which often require more than three cells, the number of base station cells deployed is generally determined based on coverage and capacity targets. Especially indoors, multiple antennas typically transmit signals from a single cell, resulting in an insufficient number of cells required for fingerprint positioning and consequently, low positioning accuracy. This embodiment of the present disclosure, by eliminating weak coverage cells at the same antenna transmission point, can resist and reduce the problem of large fluctuations in weak signals affecting positioning accuracy. Furthermore, by integrating fingerprint positioning technology, it can effectively improve indoor positioning accuracy without increasing the number and cost of wireless devices deployed.

[0046] In some embodiments, such as Figure 3 As shown, before deleting cells with signal strength less than a preset threshold transmitted under the same antenna system to obtain the first cell information within the target area, the indoor positioning method in this embodiment further includes:

[0047] S302, Based on a pre-established system parameter table, determine the cell signals transmitted under the same antenna system within the target area. The system parameter table includes the configuration information of the antenna system in the mobile communication network.

[0048] S304 sorts the signal strength of cell signals transmitted under the same antenna system according to a preset sorting rule.

[0049] In some embodiments, such as Figure 4As shown, before acquiring cell information of multiple cells within the target area, the indoor positioning method in this embodiment further includes: setting a positioning mode switch for a full-network compatible terminal that supports multiple operators, multiple frequency bands, and multiple networks; controlling the full-network compatible terminal to scan multiple networks under multiple communication standards while in positioning mode to acquire cell information of multiple cells within the target area. Specifically, the multiple networks in this embodiment include 2G, 3G, 4G, 5G, etc., which can fully utilize the full-network compatible terminal's support for multiple operators, multiple communication standards, and multiple frequency bands, and collect as many signals as possible for fingerprint positioning to solve the problem of inaccurate positioning due to the limited number of cells; at the same time, by setting a positioning mode switch, the problem of the terminal staying in a legal cell after searching for a network without performing multi-operator, multi-communication standard, and multi-frequency point searches is solved, and the terminal is modified to have a powerful network search capability and applied to positioning.

[0050] In some embodiments, this disclosure describes a method where a fully network-enabled terminal, while in positioning mode, scans multiple networks under various communication standards to obtain cell information of multiple cells within a target area. This includes: controlling the fully network-enabled terminal to read internally stored network configuration information, which includes supported communication standards, priority settings, and a predefined frequency band list; and, according to the settings in the network configuration file, controlling the fully network-enabled terminal to scan networks under each communication standard according to the priority settings and the predefined frequency band list to obtain cell information of multiple cells within the target area. Specifically, as... Figure 4 As shown, when the positioning mode is enabled, the full-network compatible terminal scans the corresponding networks in sequence according to the deployment frequency points of different communication standard networks (2G GSM, 2G CDMA, 3G WCDMA, 3G EVDO, 3G TD-SCDMA, 4G LTE FDD, 4G TD-LTE, 5G NR, etc.) to obtain multiple cell signals under a certain communication standard network and frequency. This method helps to construct the input signal space for multi-cell fingerprint positioning, and can provide usable cells with sufficient positioning accuracy at low cost without deploying more line-of-sight cells.

[0051] In some embodiments, after controlling the all-network compatible terminal to scan networks under various communication standards according to a predefined frequency band list based on priority settings in the network configuration file to obtain cell information of multiple cells within the target area, the indoor positioning method in this embodiment further includes: after scanning all frequency bands of networks under all communication standards and the scanning time reaches a preset duration, controlling the all-network compatible terminal to stop positioning mode. Specifically, as shown... Figure 4As shown, in this embodiment of the present disclosure, the network under each communication standard is scanned according to the settings in the network configuration file. After scanning a certain number of times, the system switches to the next frequency point according to the rules of the predefined frequency band list to acquire signals from multiple cells under a certain communication standard network and frequency. This process is repeated a certain number of times to reduce cell omissions and increase positioning accuracy. The system continues until all frequencies of all communication standard networks have been scanned and a preset time has been reached. At this point, the all-network-compatible terminal stops positioning mode and returns to normal mode. Considering the impact of prolonged network searching on terminal power consumption, the positioning mode is stopped after scanning is completed or the preset time has been reached, thus minimizing battery power consumption while meeting the user's device positioning needs.

[0052] In some embodiments, this disclosure describes a method for matching and locating a user within a target area by comparing the signal strength at the user's location in the second cell information with the signal strength recorded in a pre-established fingerprint database. This includes: matching and locating the user's location by comparing the signal strength at the user's location in the second cell information with the signal strength recorded in the pre-established fingerprint database to determine the user's coordinates. Specifically, as... Figure 4 As shown, the processed second cell information is matched and located with a fingerprint database that integrates multiple operators, multiple communication standards, and multiple frequency cells to obtain the location of the user equipment. Furthermore, in this embodiment of the present disclosure, a fingerprint database composed of cell information integrating multiple operators, multiple communication standards, and multiple frequency points is pre-established. Then, fingerprint matching is performed on the measurement information of the user terminal to obtain the location information of the user terminal.

[0053] In some embodiments, the indoor positioning method described above can increase the number of effective cells and effectively improve indoor positioning accuracy without increasing the number of wireless devices deployed or the cost.

[0054] Based on the same inventive concept, this disclosure also provides an indoor positioning device, as shown in the following embodiment. Since the principle by which this device embodiment solves the problem is similar to that of the above-described method embodiment, the implementation of this device embodiment can refer to the implementation of the above-described method embodiment, and repeated details will not be elaborated further.

[0055] Figure 5 This diagram illustrates an indoor positioning device according to an embodiment of the present disclosure, such as... Figure 6 As shown, the device includes:

[0057] The first cell information determination module 502 is used to delete cells whose cell signal strength transmitted under the same antenna system is less than a preset threshold, and obtain the first cell information in the target area.

[0058] The second cell information determination module 503 is used to sort the signal strength of multiple cells in the first cell information, control the number of cells in the target area to be less than a preset threshold, and obtain the second cell information in the target area.

[0059] The positioning module 504 is used to match and locate the user based on the signal strength at the user's location in the second cell information and the signal strength recorded in the pre-established fingerprint database, so as to realize the user's indoor positioning in the target area. The fingerprint database contains the coordinate information of each location in the target area and the corresponding signal strength.

[0060] The indoor positioning device provided in the embodiments of this disclosure acquires cell information of multiple cells in a target area through a cell information acquisition module. The cell information includes the signal strength of each cell, and one cell in the target area corresponds to multiple antenna systems. A first cell information determination module deletes cells whose signal strength transmitted under the same antenna system is less than a preset threshold to obtain the first cell information in the target area. A second cell information determination module sorts the signal strengths of multiple cells in the first cell information to control the number of cells in the target area to be less than a preset threshold to obtain the second cell information in the target area. A positioning module matches the signal strength of the user equipment's location in the second cell information with the signal strength recorded in a pre-established fingerprint database to achieve indoor positioning of the user in the target area. Compared to fingerprint positioning methods used in related technologies for indoor positioning, which often require more than three cells, the number of base station cells deployed is generally determined based on coverage and capacity targets. Especially indoors, multiple antennas typically transmit signals from a single cell, resulting in an insufficient number of cells required for fingerprint positioning and consequently, low positioning accuracy.

[0062] In some embodiments, the indoor positioning device in this disclosure further includes: a switch setting module, used to set a positioning mode switch for a full-network compatible terminal that supports multiple operators, multiple frequency bands, and multiple networks before acquiring cell information of multiple cells in the target area; and a scanning module, used to control the full-network compatible terminal to scan multiple networks under multiple communication standards in the state where the positioning mode is enabled, so as to acquire cell information of multiple cells in the target area.

[0063] In some embodiments of this disclosure, the scanning module is further configured to control the full-network-compatible terminal to read the network configuration information stored internally. The network configuration information includes supported communication standards, priority settings, and a predefined frequency band list. According to the settings in the network configuration file, the full-network-compatible terminal is controlled to scan the networks under each communication standard according to the priority settings and the predefined frequency band list to obtain cell information of multiple cells in the target area.

[0065] In some embodiments of this disclosure, the positioning module is further configured to match and locate the user's position based on the signal strength at the user's location in the second cell information and the signal strength recorded in a pre-established fingerprint database, thereby determining the coordinate information of the user's location.
