Description

Positioning method, device, equipment and storage medium

Technical Field

The present application relates to the field of network communications, and in particular, to a positioning method, apparatus, device, and storage medium.

Background

The mobile phone positioning refers to a technology or a service for acquiring the position information of a mobile phone or a terminal user through a specific positioning technology and marking the position of a positioned object on an electronic map. Currently, the most common way for positioning a mobile phone is to perform positioning based on a base station set by a network operator, that is, the mobile phone position is determined by using the distance measured by the base station to the mobile phone.

Although the mobile phone is not required to have the GPS positioning capability in the above way, the positioning accuracy greatly depends on the distribution of the base stations and the size of the coverage area. At present, network operators have few base stations, and particularly in remote areas, even a very small number of base stations may exist, which causes inaccurate positioning information. Therefore, more precise positioning methods need to be studied.

The method is based on SIM cards of different operators to acquire a plurality of cell information of the different operators, and then the third party map software is utilized to process the cell information to determine the position of the user, so that the user can be positioned more accurately.

In a first aspect, the present application provides a positioning method, including: acquiring a cell set and cell parameters of each cell in the cell set, wherein the cell set comprises a first cell and a second cell, the first cell is acquired based on a first SIM card, the second cell is acquired based on a second SIM card, the first SIM card and the second SIM card belong to different operators, and the cell parameters comprise parameters representing a position area of the cell and parameters representing communication quality of the cell; selecting N target cells with better communication quality from the cell set based on the cell parameter of each cell, wherein N is an integer greater than 1; determining location information of a target object based on the N target cells.

In a positioning method commonly used by a terminal, base station information around the terminal can be determined through a mobile phone signal received by an SIM card, cell information can be determined according to the base station information, and the position of the terminal can be calculated through the cell information. It will be appreciated that in some remote areas there may be a very small number of base stations, which may be distributed relatively discretely, resulting in poor communication quality. At this time, the target object may not be accurately located by the base station set up by only one network operator. Therefore, the positioning method provided by the application achieves the effect of more accurate positioning by acquiring the cell information of different operators. That is, in the method, the first SIM card and the second SIM card belong to different operators, for example, the first SIM card may be a telephone card of china mobile, and the second SIM card may be a telephone card of china unicom. Compared with the number of the base station information acquired by only one of the two SIM cards, the number of the base stations and the cells with good communication quality acquired by the two SIM cards is more, and the target object can be positioned more accurately.

In a possible implementation manner of the first aspect, the obtaining the set of cells includes: acquiring the first cell and at least one first adjacent cell of the first cell based on the first SIM card; acquiring the second cell and at least one second adjacent cell of the second cell based on the second SIM card; and combining the first cell, the second cell, at least one first neighbor cell and the at least one second neighbor cell to obtain the cell set.

It will be appreciated that the more base stations that can be connected in the vicinity of the terminal, the more accurate the terminal can be located. Therefore, in this embodiment, in addition to obtaining the first cell and the second cell, a plurality of neighboring cells of the first cell are obtained based on the first SIM card, and a plurality of neighboring cells of the second cell are obtained based on the second SIM card, so that when selecting a cell, it is more beneficial to obtain a target cell with better communication quality, and more accurately locate the target object.

In a possible implementation manner of the first aspect, the determining location information of a target object based on the N target cells includes: sending request information to a third party application, wherein the request information comprises the parameters for representing the communication quality of the cell, and the third party application is used for determining the position information according to the request information; and receiving the position information returned by the third-party application.

The third-party application can be third-party map software supporting port calling, such as a 'height map', 'Baidu map', and the like.

In this application, "at least one" means one or more, "a plurality" means two or more, "at least two" means two or three and three or more, "and/or" for describing an association relationship of associated objects, which means that there may be three relationships, for example, "a and/or B" may mean: only A, only B and both A and B are present, wherein A and B may be singular or plural.

For example, at least one (one) of a, b, or c, may represent: a, b, c, "a and b," a and c, "" b and c, "or" a and b and c.

In order to describe the scheme of the present invention more clearly, some knowledge related to the positioning method, apparatus, device and storage medium provided in the embodiments of the present application is introduced below.

(1) Cell

A cell, also called a cell, refers to an area covered by one or a part of a base station (sector antenna) in a cellular mobile communication system, in which a mobile station can reliably communicate with the base station via a radio channel.

(2) Cell parameters

The cell parameters include parameters characterizing a location area of the cell and parameters characterizing communication quality of the cell, such as a mobile network code, a tracking area code, a received signal strength, a reference signal received power, and a sector code. Wherein:

the Mobile Network Code (MNC) is used for identifying a Mobile Network to which a Mobile client belongs, and has 2-3 digits in total. Within the same country, it can be distinguished by the MNC if there are multiple public land mobile networks. The China Mobile System uses 00, 02, 04, 07, the China Unicom System uses 01, 06, 09, the China telecom System uses 03, 05, the telecom 4G uses 11, the China iron Tong System uses 20. Therefore, 460-00 represents China Mobile, 460-01 represents China Unicom, and 460-03 represents China Telecommunications.

Tracking Area Code (TAC) is self-allocated by an operator, and mainly plays a role of unique identification for positioning of a mobile user.

Received Signal Strength (RSSI) in a wireless network represents the Strength of a Signal, which decays with increasing distance, typically being negative, with values closer to zero indicating higher Signal Strength. The RSSI continues to be too low, indicating that the uplink signal received by the base station is too weak, which may result in demodulation failure. The RSSI is continuously too high, which indicates that the received uplink signals are too strong and interfere with each other too much, thereby affecting the signal demodulation.

Reference Signal Receiving Power (RSRP) represents the LTE Reference Signal received quality, and this metric ranks the different LTE candidate cells primarily according to Signal quality, which is used as an input for handover and cell reselection decisions. RSRQ is defined as the ratio of N RSRP/(LTE carrier RSSI), where N is the number of Resource Blocks (RBs) of the LTE carrier RSSI measurement bandwidth. RSRQ achieves an efficient way to report the effect of combining signal strength and interference, reflecting and indicating the signal-to-noise and interference levels of the current channel quality.

The sector Code (CI), which may also be referred to as a Cell Identity, is a code that a network operator needs to assign to all cells in the network in order to uniquely represent each Cell in the public land mobile network. The CI, in combination with the location area identity, identifies each BTS in the network and the cell it covers, representing a sector of a mobile communications base station. Location area codes, sector codes plus country codes (e.g., 86, china), and operator identification codes (e.g., (china mobile-01), can be used for globally unique positioning with an accuracy of about 500, 600 meters.

(3) Base station location

The mobile communication network is composed of a plurality of base stations (big iron towers) which are arranged according to a certain rule, each base station covers a regular hexagonal area, each regular hexagonal area is called a cell, each cell (base station) has a fixed ID (number), the formed network is similar to a cell, the main characteristic of the formed network is the mobility of the terminal, and the formed network has the functions of handover and automatic roaming across local networks. Base station positioning is to measure downlink pilot signals of different base stations through a mobile phone to obtain arrival time of downlink pilot signals of different base stations) or arrival time difference, and the position of the mobile phone can be calculated according to the measurement result and coordinates of the base stations by generally adopting a trigonometric formula estimation algorithm. The actual position estimation algorithm needs to consider the case of multi-base station (3 or more than 3) positioning, so the algorithm is much more complex. Generally speaking, the more base stations the mobile station measures, the higher the measurement accuracy, and the more obvious the improvement of the positioning performance. As long as the mobile phone is not in the offline mode, the mobile communication operator can know which cell the mobile phone is located in at any time, and the mobile phone also has the ID of the current cell. The accuracy of the positioning depends on the radius of the cell where the mobile phone is located, and ranges from hundreds of meters to dozens of kilometers.

(4) Neighbor cell

The neighboring cell is a cell overlapping with a certain cell and having a handover relationship, and one cell may have a plurality of neighboring cells. In a network environment, there are many neighboring cells having a handover relationship with a certain cell, and the number of the neighboring cells may exceed 40, so as to ensure that the mobile phone can perform smooth alternation of services among a plurality of cells defining the neighboring cell relationship in a mobile state without interruption.

Fig. 1 is a scene schematic diagram of a terminal performing base station positioning according to an embodiment of the present application. As shown in fig. 1, a SIM card of a certain network operator (for example, china mobile or chinese telecom) is inserted into the terminal 10, so that when the terminal 10 performs base station location, the terminal 10 can search nearby base stations of the network operator, that is, the base station 101, the base station 102, the base station 103, and the base station 104 shown in fig. 1, based on the SIM card. It should be understood that the hexagons shown below each base station in fig. 1 are for the convenience of the reader only, and indicate that the signal coverage of each communication base station making up the network coverage is hexagonal. Base station 101 is the closest to terminal 10, while base stations 102, 103 and 104 are relatively further away from terminal 10. It will be appreciated that the accuracy of the base station location depends largely on the distribution of base stations and the size of the coverage area. Therefore, in the process of positioning the terminal 10 by using the base stations 101, 102, 103 and 104, the distances between the base stations 102, 103 and 104 and the terminal 10 are relatively long, which may cause the position information acquired finally to be inaccurate.

In view of the above drawbacks, an embodiment of the present application provides a positioning method. The method is based on SIM cards of different operators to acquire a plurality of cell information of the different operators, and then the third party map software is utilized to process the cell information to determine the position of the user, so that the user can be positioned more accurately. As shown in fig. 2, the method may include the steps of:

201. the electronic device obtains a set of cells and cell parameters for each cell in the set of cells.

The electronic device is a device supporting the use of two GSM networks, and may be a mobile phone (mobile phone), a vehicle-mounted device (e.g., an On Board Unit (OBU)), a tablet computer (pad), a computer with a data transmission and reception function (e.g., a laptop computer, a palmtop computer, etc.), a Mobile Internet Device (MID), a terminal in industrial control (industrial control), a wireless terminal in self driving (self driving), a terminal in transportation security (transportation security), a terminal in smart city (smart city), a terminal device in a 5G network, or a terminal device in a future evolved Public Land Mobile Network (PLMN), etc.; it is understood that the present application is not limited to the specific form of the electronic device.

The cell set includes a first cell and a second cell, the first cell is obtained based on a first SIM card, the second cell is obtained based on a second SIM card, the first SIM card and the second SIM card belong to different operators, and the cell parameters include a parameter representing a location area of the cell and a parameter representing communication quality of the cell.

Specifically, the first SIM card and the second SIM card may be SIM cards of any two operators in "china telecom", "china mobile", and "china unicom". For example, the first SIM card may be a "china telecom" SIM card, and the second SIM card may be a "china unicom" SIM card; or the SIM card may be a "china mobile" SIM card, the second SIM card may be a "china telecommunications" SIM card, and the first SIM card and the second SIM card may also be a combination of other SIM cards of two different operators, which is not described herein again.

The electronic device may first determine, based on the first SIM card, an operator to which the first SIM card belongs, and select a cellular mobile communication network of a certain standard of the operator. Then, the electronic device may perform initial cell selection, and search for a cell belonging to the cellular mobile communication network in the supported full frequency band. For example, the electronic device may search for a cell with the strongest signal on each frequency point, and select the cell as the first cell when finding a suitable cell. Similarly, the electronic device may first obtain, based on the second SIM card, an operator to which the second SIM card belongs and a cell of the operator in the same manner, as the second cell.

In addition, if the electronic device stores prior information, it indicates that the electronic device has stored information related to carrier frequency, and may also include information of some cell parameters. The electronic device will preferentially select the cell with the relevant information, and if appropriate, the electronic device will select it and camp on; if not, the electronic device initiates an initial cell selection procedure.

The cell parameters include a parameter characterizing a location area of the cell and a parameter characterizing communication quality of the cell. Specifically, the cell parameters may include parameters such as a mobile network code MNC, a tracking area code MCC, a tracking area code TAC, a received signal strength RSSI, a reference signal received power RSRP, and a sector code CI. The specific meaning and use of each parameter can refer to the foregoing description, and are not repeated herein.

In an optional embodiment, after the electronic device determines the first cell based on the first SIM card, the electronic device may further search for a neighboring cell (hereinafter, referred to as a first neighboring cell) of the first cell by searching for the same downlink synchronization signal based on the first cell; then, the electronic device may switch the acquisition source of the cell information from the first SIM card to the second SIM card, and after determining the second cell based on the first SIM card, search for a neighboring cell (hereinafter, referred to as a second neighboring cell) of the second cell in the same manner; and using the total set of the first cell, the second cell, the first neighbor cell and the second neighbor cell as the cell set. It should be understood that the present application does not limit the number of the first neighbor cell and the second neighbor cell. Generally, the number of the first neighbor cell or the second neighbor cell is 0 to 8. In addition, in the process of acquiring the neighboring cells, the electronic device may also acquire cell parameters of each neighboring cell correspondingly.

To further explain the cell set, an embodiment of the present application provides a scene diagram of a terminal performing base station positioning. As shown in fig. 3, two different network operators (e.g., china mobile and chinese telecommunications) SIM cards are inserted into the terminal 30, where the chinese mobile SIM card is equivalent to the first SIM card and the chinese telecommunications SIM card is equivalent to the second SIM card. Therefore, when the terminal 30 performs the base station positioning, the terminal 30 may first search for a nearby base station of the china mobile, that is, the base station 301, the base station 302, the base station 303, and the base station 304 shown in fig. 3, based on the SIM card of the china mobile; base station 301 is closest to terminal 30, and base stations 302, 303, and 304 are relatively further away from terminal 30. Similarly, the terminal 30 may search for nearby base stations of the network operator, i.e. the base station 305, the base station 306, the base station 307, and the base station 308 shown in fig. 3, based on the SIM card of the chinese telecom. Wherein base station 305 is closest to terminal 308, and base station 306, and base station 307 are relatively further from terminal 30. The coverage area of the signal of each of the china base stations 301 to 308 can be regarded as the cell set.

202. And the electronic equipment selects N target cells with better communication quality from the cell set based on the cell parameters of each cell.

It can be understood that, when the communication quality of a cell is better, the closer the electronic device is to the corresponding base station, the more accurate the positioning information obtained based on the cell is. Therefore, in the method, after obtaining the cell set, the electronic device selects the cells in the cell set based on the communication quality of each cell in the cell set, and obtains the cell with better communication quality, that is, the target cell.

In an optional embodiment, to comply with a communication standard of a 4G-LTE communication system, the electronic device may select cells in the cell set according to reference signal received power RSRP in the cell parameter, so as to obtain the N target cells. Therefore, the finally selected N target cells are ensured to be N cells with the front communication quality in the cell set as far as possible.

Optionally, the N target cells are N cells with the best communication quality in the cell set. Wherein N is an integer greater than 0; typically, N has a value of 3.

To specifically explain by taking the scenario diagram shown in fig. 3 as an example, it is assumed that the cells corresponding to the base stations 301 to 304 are cells 001 to 004, the cells corresponding to the base stations 305 to 308 are cells 005 to 008, and RSRP values of the cells in the cells 001 to 008 are shown in the following table 1:

TABLE 1

Cell	RSRP
		001	-50
002	-75
		003	-90
004	-95
		005	-37
006	-80
		007	-80
008	-42

It can be understood that the larger the RSRP value, the better the communication quality of the cell. Therefore, as can be seen from the RSRP values of the cells in table 1, in the cell 001-cell 008, if the RSRP values of the communications of the cell 001, the cell 005, and the cell 008 are large and the communications quality is good, the terminal 30 uses the cell 001, the cell 005, and the cell 008 as the target cell from the cell set. The cell 001 is a cell obtained by the terminal 30 based on the first SIM card, and the cell 005 and the cell 008 are cells obtained by the terminal 30 based on the second SIM card.

In an optional embodiment, to comply with a communication standard of a 2G mobile communication system, the electronic device may further select cells in the cell set according to the RSSI in the cell parameter to obtain the N target cells, so as to ensure that the finally selected N target cells are N cells with the highest communication quality in the cell set.

203. The electronic device determines position information of a target object based on the N target cells.

The third-party application may be third-party map software supporting port invocation, such as a "height map", a "Baidu map", and the like, which is not limited in the present application. In this embodiment, the terminal may send the relevant parameters (including a mobile country code, a mobile network code, a tracking area code, and the like) of the N target cells to the map software, and the map software may calculate the position of the electronic device by combining the coordinates of the base station after acquiring the parameters of the cells.
