[0034] Those skilled in the art will know that Figure 1 The number of terminals, networks, and network-side devices in the example is only illustrative, and any number of terminals, networks, and network-side devices may be provided according to actual needs. The embodiments of the present disclosure are not limited to this.

[0035] Under the above system architecture, an indoor positioning method is provided in an embodiment of the present disclosure, and the method can be executed by any electronic device with computing and processing capabilities.

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

[0037] Figure 2 A schematic diagram of an indoor positioning method in an embodiment of the present disclosure is shown, and the method includes the following steps:

[0038] S202, obtaining cell information of multiple cells in a target area, wherein the cell information includes a 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 the embodiments of the present disclosure can be any geographical location or a certain range that needs to be located, which can be a completely enclosed room or an open-air playground. For example, the target area can be a shopping mall. The cell in the embodiments of the present disclosure is the basic geographical service unit of the mobile communication network, which is covered and served by a base station. There may be multiple cells in the target area, which are covered by multiple base stations. This means that the signal strength at certain locations in the target area may be interfered with by multiple signals. In addition, the antenna system in the embodiments of the present disclosure refers to a device composed of one or more antennas and related components for transmitting and receiving radio signals.

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

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

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

[0043] It should be noted that in the embodiment of the present disclosure, the signal strengths of multiple cells in the first cell information can be sorted in order from large to small, or in order from small to large, and the cells with smaller signal strength in the sequence can be deleted. For example, the embodiment of the present disclosure maintains the number of cells within a certain range by deleting cells with smaller signal strength. The preset threshold in the embodiment of the present disclosure can be set to 8, and only 7 cells with higher signal strength are retained, which can not only ensure positioning accuracy, but also reduce the calculation amount and time consumption caused by too many cells, thereby improving positioning efficiency.

[0044] S208, matching and positioning the signal strength at the location of the user equipment 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, wherein the fingerprint database contains coordinate information of each location in the target area and the signal strength corresponding to each location.

[0045] The indoor positioning method provided in the embodiment of the present disclosure first obtains cell information of multiple cells in a target area, wherein the cell information includes the signal strength of each cell, and one cell in the target area corresponds to multiple antenna systems; secondly, deletes cells whose cell signal strength transmitted by the same antenna system is less than a preset threshold, and obtains first cell information in the target area; then, sorts the signal strengths of multiple cells in the first cell information, controls the number of cells in the target area to be less than a preset threshold, and obtains second cell information in the target area; finally, matches and locates the user in the target area according to the signal strength at the location of the user equipment in the second cell information and the signal strength recorded in a pre-established fingerprint database, thereby realizing indoor positioning of the user in the target area. Compared with the fingerprint positioning method used in related technologies for indoor positioning, the number of cells required is often greater than 3, but the number of base station cells deployed is generally determined according to coverage and capacity targets. Especially indoors, multiple antennas generally transmit a cell signal, resulting in an insufficient number of cells required for fingerprint positioning, leading to low positioning accuracy. The disclosed embodiment eliminates weak coverage cells at the same antenna transmission point, thereby resisting and reducing the problem of large fluctuations in weak signals that affect positioning accuracy. It also integrates fingerprint positioning technology, which can effectively improve indoor positioning accuracy without increasing the number and cost of wireless device deployment.

[0046] In some embodiments, Figure 3 As shown, in the embodiment of the present disclosure, before deleting the cells whose cell signal strength transmitted by the same antenna system is less than the preset threshold and obtaining the first cell information in the target area, the indoor positioning method in the embodiment of the present disclosure further includes:

[0047] S302: Determine cell signals transmitted by the same antenna system in a target area according to a pre-established system engineering parameter table, where the system engineering parameter table includes configuration information of the antenna system in the mobile communication network.

[0048] S304: sort the signal strengths of the cell signals transmitted by the same antenna system according to a preset sorting rule.

[0049] In some embodiments, Figure 4As shown, before obtaining the cell information of multiple cells in the target area, the indoor positioning method in the disclosed embodiment also includes: setting a positioning mode switch for the all-network terminal that supports multiple operators, multiple frequency bands and multiple networks; controlling the all-network terminal to scan multiple networks under multiple communication standards when the positioning mode is turned on to obtain the cell information of multiple cells in the target area. Specifically, the multiple networks in the disclosed embodiment include 2G, 3G, 4G, 5G, etc., so that the support of the all-network terminal for multiple operators, multiple communication standards, and multiple frequency bands can be fully utilized, and multiple signals can be collected as much as possible for fingerprint positioning to solve the problem of inaccurate positioning due to the limited number of cells; at the same time, the problem that the terminal currently resides in a legal cell after searching the network without searching multiple operators, multiple communication standards and multiple frequency points is solved by setting the positioning mode switch, and the terminal has a strong network search capability and is applied to positioning.

[0050] In some embodiments, the disclosed embodiments control the full network terminal to scan multiple networks under multiple communication standards when the positioning mode is turned on to obtain cell information of multiple cells in the target area, including: controlling the full network terminal to read the internally stored network configuration information, 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, controlling the full network terminal to scan the networks under each communication standard according to the predefined frequency band list according to the priority settings to obtain cell information of multiple cells in the target area. Specifically, Figure 4 As shown, when the positioning mode is turned on, the all-network terminal scans the corresponding networks in accordance with different communication standard networks (2G GSM, 2G CDMA, 3G WCDMA, 3G EVDO, 3G TD-SCDMA, 4G LTE FDD, 4G TD-LTE, 5G NR, etc.) in the order of corresponding deployment frequencies, and obtains multiple cell signals under certain communication standard networks and frequencies. This method helps to construct the input signal space for multi-cell fingerprint positioning, and without deploying more line-of-sight cells, cells that meet the positioning accuracy can be used at low cost.

[0051] In some embodiments, after the disclosed embodiment controls the full network terminal to scan the network under each communication standard according to the predefined frequency band list according to the priority setting according to the setting in the network configuration file to obtain the cell information of multiple cells in the target area, the indoor positioning method in the disclosed embodiment further includes: after scanning all frequency bands of the network under all communication standards and the scanning time reaches a preset time length, controlling the full network terminal to stop the positioning mode. Specifically, Figure 4As shown, the disclosed embodiment scans the networks under each communication standard according to the settings in the network configuration file according to the predefined frequency band list. After scanning a certain number of times, it will switch to the next frequency point according to the rules of the predefined frequency band list to obtain multiple cell signals under a certain communication standard network and frequency, and execute it a certain number of times. By increasing the number of scans, the cell omissions are reduced and the positioning accuracy is increased; until all frequency points of all communication standard networks are scanned and the preset time is reached, the full network terminal stops the positioning mode and returns to the normal mode. Considering the impact of long-term network search on terminal power consumption, the positioning mode is stopped after the scan is completed or the preset time is reached, so as to minimize battery power consumption while meeting the user equipment positioning requirements.

[0052] In some embodiments, the disclosed embodiments match and locate the signal strength at the user'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, including: matching and locating the signal strength at the user's location in the second cell information with the signal strength recorded in a pre-established fingerprint database to determine the coordinate information at the user's location. Specifically, Figure 4 As shown, the processed second cell information is matched and positioned with a fingerprint database that integrates multi-operation and multi-communication standard multi-frequency cells to obtain the location of the user equipment. Furthermore, the embodiment of the present disclosure pre-establishes a fingerprint database consisting of cell information that integrates multi-operator multi-communication standard multi-frequency points, and then performs fingerprint matching on the measurement information of the positioned user terminal to obtain the location information of the user terminal.

[0053] In some embodiments, the embodiments of the present disclosure can increase the number of effective cells through the above-mentioned indoor positioning method, and effectively improve the indoor positioning accuracy without increasing the number and cost of wireless device deployment.
