Find gates, platforms, or other facilities at an airport or train station. Learn about exhibit information and view exhibitions more effectively in museums. Identify the location of medical staff or medical equipment in a hospital. Positioning of firefighters in a burning building, etc. When the user goes to the meeting room for a meeting, the terminal device will automatically turn on the silent mode according to the indoor positioning result. When a user sees an item of interest when shopping in the mall but is still hesitating, he takes a photo and automatically tags the photo with a location. When he decides to buy next time, the user can navigate to the location of the item according to the navigation of the terminal device. These will bring convenience to users' daily life and work, as well as in emergency situations.

The indoor positioning method provided by the embodiment of the present application uses the measurement report reported by the terminal device itself to locate the terminal device, thereby achieving accurate and reliable positioning of the indoor terminal device. Moreover, the measurement report is the data collected continuously in the daily wireless communication, and no additional data collection device is required, which effectively reduces the cost of indoor positioning, and thus is conducive to large-scale popularization and application.

The implementation of the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows a simplified schematic diagram of a system architecture to which the embodiments of the present application can be applied. As shown in Figure 1, the system architecture may include: terminal equipment, an indoor distribution system and an indoor positioning device. Wherein, the room distribution system can be connected with the indoor positioning device through the network. The network may be, for example, an Ethernet, a radio access network (Radio Access Network, RAN), a wireless local area network (Wireless Local Area Networks, WLAN), and the like. In the embodiment of this application, it is assumed that the room distribution system covers the fixed area shown in Figure 1, and the fixed area is divided into M areas, the coverage of cell 1 and the coverage of cell 2 include the physical range of area 1, and the terminal When the device is within the physical range of area 1, it can receive the signal of cell 1 and cell 2.

It should be noted that the indoor distribution system included in the system architecture described in the embodiment of this application is just an example. In practical applications, if there is no indoor distribution system in a fixed area (inside a building), then the measurement report can be reported through the outdoor macro station. Send to the indoor positioning device.

The indoor positioning device may be an existing network management system, that is, a background server.

Fig. 2 is a flow chart of an indoor positioning method provided by the embodiment of the present application. As shown in Fig. 2, the method may include:

S201. Acquire a measurement report set of a terminal device.

The terminal equipment is located in a fixed area, and the fixed area may be the above-mentioned shopping malls, hospitals, and the like. The terminal equipment can automatically measure the signal quality from the terminal equipment to the room branch or macro station, obtain the measurement report of the terminal equipment, and report it to the network management system. The measurement report of the terminal device includes the identity of the serving cell, the RSRP of the serving cell, the RSRQ of the serving cell, the RSRP of the neighboring cell, and the RSRQ of the neighboring cell. The serving cell is the cell where the terminal device communicates, and the neighboring cell is the cell adjacent to the serving cell. . The indoor distribution system described in the embodiment of this application refers to a small base station built by an operator in a building, such as a mushroom head. If the indoor distribution system is set in the fixed area, the screening measurement report can be screened according to the cell identification of the indoor base station in the fixed area. In another practicable way, if no indoor distribution system is set in the fixed area, the service cell can be screened out based on the macro stations around the fixed area, the longitude and latitude of the fixed area and the latitude and longitude of the macro station to judge whether the terminal equipment is around the fixed area It is the measurement report of the cell of the macro station around the fixed area, so as to obtain the measurement report set of the terminal equipment.

S202. Predict the physical location of the terminal device according to the measurement report set of the terminal device and the positioning model, and obtain the positioning information of the terminal device.

According to the measurement report set of the terminal device and the positioning model, use the classification algorithm to determine the location identifier corresponding to the measurement report set of the terminal device, that is, use the classification algorithm to determine the row vector similar to the wireless environment information represented by the measurement report set of the terminal device in the positioning model The wireless environment information of the measurement report represented by , determines the location identifier corresponding to the similar wireless environment information in the positioning model as the location identifier corresponding to the measurement report set of the terminal device, therefore, determines the location identifier corresponding to the measurement report set of the terminal device as The location information of the terminal device. The positioning model is used to represent the corresponding relationship between the physical location and the measurement report of the physical location. The measurement report is used to represent the collected wireless environment information of the physical location.

S203. Send the positioning information of the terminal device to the terminal device.

Further, before obtaining the measurement report set of the terminal device, that is, S201, the indoor positioning device may pre-build a positioning model, as shown in FIG. 3 , the indoor positioning method described in the embodiment of the present application further includes the following steps:

S204. Obtain K measurement reports of the fixed area.

The fixed area can be the above-mentioned shopping malls, hospitals, etc. Communication maintenance personnel can use the test terminal to conduct drive tests on every place and corner of the fixed area, and obtain the measurement report of each place and corner. Usually, the test terminal reports a measurement report to the macro station or indoor branch in 1 ms or 2 ms. There can be multiple measurement reports in each place and corner. Therefore, a total of K measurement reports can be obtained in a fixed area, and K is a positive integer greater than 1. Each measurement report includes multiple cell identities and the RSRP and RSRQ of the cell corresponding to each cell id. The cells corresponding to the multiple cell identities include the serving cell and the neighboring cells of the serving cell. The serving cell provides communication services for the test terminal. A cell, and an adjacent cell is a cell adjacent to the serving cell. A measurement report includes the cell ID of a serving cell and the IDs of more than one neighboring cell.

S205. Construct a positioning model according to the K measurement reports in the fixed area.

First, the fixed area is divided, and the divided area of the fixed area is encoded. For example, when the fixed area is a shopping mall, the shopping mall can be divided according to the stores, and each store can be coded. When the fixed area is a hospital, the hospital can be divided according to the diagnosis and treatment areas of the departments of the hospital, and each department can be coded. Thus, the position identifier of the fixed area is obtained. The communication personnel can test the fixed area with the terminal equipment used for drive testing. The communication personnel know the area they are in and the code of the area. The communication personnel can conduct tests in different areas. Therefore, during the modeling period, the measurement report and Region codes correspond to each other. Therefore, for each measurement report in the K measurement reports, the location identifier of each measurement report in the K measurement reports is obtained according to the location identifier of the fixed area. Then, N cell identities are determined according to the cell identities included in the K measurement reports, which is equivalent to determining how many cells are included in the fixed area, the N cell identities are all different, and N is a positive integer greater than 1. Secondly, a utility matrix is generated according to the K measurement reports, N cell identities, and the location identifier of each measurement report in the K measurement reports. The utility matrix is a K×2N matrix. K means that the utility matrix includes K row vectors, and 2N means The utility matrix includes 2N columns, and each row vector represents a measurement report corresponding to a location identifier corresponding to a physical location indicated by the location identifier. A row vector includes 2N columns, that is, RSRP and RSRQ of N cells in the fixed area. Each column indicates the RSRP or RSRQ of the cell corresponding to the cell identifier, and the 2N columns are equivalent to storing whether each measurement report receives a signal in these N cells, that is, whether there is RSRP and RSRQ, and fill in the corresponding position. For example, when the measurement report includes RSRP and RSRQ of cell i, two columns of RSRP and RSRQ corresponding to cell i are filled with RSRP and RSRQ of cell i, and i ranges from 1 to N. The measurement report may include RSRP and RSRQ of multiple cells, and this embodiment of the present application does not limit how many RSRP and RSRQ of cells are included in the measurement report. When the measurement report does not include the RSRP and RSRQ of other cells, the RSRP and RSRQ columns of the corresponding cell are filled with 0.

For example, assuming that measurement report 1 is a measurement report for performing a drive test on area 1, measurement report 1 includes cell ID 1 and cell ID 2, and the RSRP and RSRQ of the cell corresponding to cell ID 1, and the RSRP of the cell corresponding to cell ID 2 For RSRQ, the cell corresponding to cell ID 1 is the serving cell, and the cell corresponding to cell ID 2 is the neighboring cell. It is assumed that R ₁ (ij) in the utility matrix represents the RSRP of the jth cell in area i, and R ₂ (ij) represents the RSRQ of the jth cell in area i. At this time, the first row vector of the utility matrix represents the measurement report 1 for the drive test of area 1, and the first column and the second column of the first row vector fill in the RSRP of the cell corresponding to the cell identity 1 of area 1 (R ₁ ( 11)) and RSRQ (R ₂ (11)), the third column and the fourth column of the first row vector fill in the RSRP (R ₁ (12)) and RSRQ (R ₂ ( 12)). In addition, in an actual drive test, multiple measurement reports will be obtained when a drive test is performed on an area, and a positioning model needs to be constructed based on the measurement reports of all areas in a fixed area. For example, measurement report 2 is another measurement report for performing a drive test on area 1. Measurement report 2 includes cell ID 1 and cell ID 2, the RSRP and RSRQ of the cell corresponding to cell ID 1, and the RSRP of the cell corresponding to cell ID 2. For RSRQ, the cell corresponding to cell ID 1 is the serving cell, and the cell corresponding to cell ID 2 is the neighboring cell. Similarly, the second row vector of the utility matrix represents the measurement report 2 for the drive test of area 1, and the first and second columns of the second row vector fill in the RSRP of the cell corresponding to the cell identity 1 of area 1 (R ₁ ( 11)) and RSRQ (R ₂ (11)), the third column and the fourth column of the second row vector fill in the RSRP (R ₁ (12)) and RSRQ (R ₂ ( 12)). Measurement report 3 is a measurement report for performing a drive test on area 2. Measurement report 3 includes cell ID 1 and cell ID 3, as well as the RSRP and RSRQ of the cell corresponding to cell ID 1, the RSRP and RSRQ of the cell corresponding to cell ID 3, and the cell The cell corresponding to ID 1 is the serving cell, and the cell corresponding to cell ID 3 is the neighboring cell. At this time, the third row vector of the utility matrix represents the measurement report for the drive test of area 2, and the first column and the second column of the third row vector fill in the RSRP of the cell corresponding to the cell identity 1 of area 2 (R ₁ (21 )) and RSRQ(R ₂ (21)), the fifth column and the sixth column of the third row vector fill in the RSRP (R ₁ (23)) and RSRQ (R ₂ (23)) of the cell corresponding to the cell identification 3 of area 2 )).

Similarly, the measurement report K-1 is a measurement report for performing a drive test on the area M-1. The measurement report K-1 includes the cell ID N and the cell ID N-2, and the RSRP and RSRQ of the cell corresponding to the cell ID N. The RSRP and RSRQ of the cell corresponding to the identification N-2, the cell corresponding to the cell identification N is the serving cell, and the cell corresponding to the cell identification N-2 is the neighboring cell. At this time, the 2N-5th column and the 2N-4th column of the K-1 row vector of the utility matrix fill in the RSRP of the cell corresponding to the cell identifier N-2 of the area M-1 (R ₁ ((M-1)( N-2))) and RSRQ (R ₂ ((M-1)(N-2))), the 2N-1th column and the 2Nth column of the K-1th row vector are filled with the cell identifier N of the area M-1 RSRP(R ₁ ((M-1)N)) and RSRQ(R ₂ ((M-1)N)) of the corresponding cell. The measurement report K is a measurement report for performing a drive test on the area M. The measurement report K includes the cell ID N and the cell ID N-1, as well as the RSRP and RSRQ of the cell corresponding to the cell ID N, and the RSRP of the cell corresponding to the cell ID N-1. For RSRQ, the cell corresponding to the cell ID N is the serving cell, and the cell corresponding to the cell ID N-1 is the neighboring cell. At this time, the 2N-3th column and the 2N-2th column of the K-th row vector of the utility matrix are filled with the RSRP(R ₁ (M(N-1))) and RSRQ of the cell corresponding to the cell identifier N-1 of the area M (R ₂ (M(N-1))), the 2N-1th column and the 2Nth column of the K-th row vector are filled with the RSRP(R ₁ (MN)) and RSRQ(R ₂ (MN)). The utility matrix can be:

Among them, r ₁ is the location identifier of area 1, r ₂ is the location identifier of area 2, r _M-1 is the location identifier of area M-1, and r _M is the location identifier of area M. Of course, two different row vectors can correspond to the same location identifier. The foregoing utility matrix is just an example. In practical applications, the utility matrix may be specifically generated according to the area division of the fixed area and the measurement report, which is not limited in this embodiment of the present application.

Finally, the utility matrix is trained according to the classification algorithm to obtain the localization model. The classification algorithm may be a Bayesian classification algorithm, or other classification algorithms in practical applications, and this embodiment of the present application is only an example for illustration.

The indoor positioning method provided by the embodiment of the present application uses the measurement report reported by the terminal device itself to locate the terminal device, thereby achieving accurate and reliable positioning of the indoor terminal device. Moreover, the measurement report is the data collected continuously in the daily wireless communication, and no additional data collection device is required, which effectively reduces the cost of indoor positioning, and thus is conducive to large-scale popularization and application.

In addition, for the operator, the location information of the user can be used to locate the network problem, so that the location of the network problem is more accurate, and it is convenient to further troubleshoot the network problem.
