Description

Terminal positioning method, device, server and storage medium based on azimuth angle

Technical Field

The embodiment of the invention relates to the technical field of mobile communication, in particular to a terminal positioning method, a terminal positioning device, a server and a storage medium based on an azimuth angle.

Background

In the field of mobile user location, algorithms such as fingerprint location, triangulation location, TA and AOA location based on MR data reported by a mobile user are the most commonly used algorithms in the field of mobile network user location at present. The fingerprint positioning depends on a fingerprint database, and if the area to be positioned has no fingerprint, the accurate positioning cannot be carried out; triangulation positioning is required to be carried out by a user to simultaneously keep communicating with more than three base stations, and is not applicable in a situation of an island station or a situation below three stations; the TA and AOA algorithms require that the base station antenna must be an array antenna, which is too high in hardware requirement. Therefore, any algorithm has the limitation of use, and the positioning accuracy is reduced or even the positioning cannot be performed beyond the used scene. In the area with denser wireless stations, the number of users is more, the more base station signals can be received by the users, the more optional positioning algorithms are available, and the positioning accuracy relative to the users is also high.

When a user is located at the edge of an urban area, a suburb area or a suburb area such as a vast rural area, base stations are sparse, the station distance is too large, fingerprint data are rare, and few selectable positioning algorithms exist, so that the positioning accuracy is reduced.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. A process may be terminated when its operations are completed, but may have additional steps not included in the figure. A process may correspond to a method, a function, a procedure, a subroutine, a subprogram, etc.

Furthermore, the terms "first," "second," and the like may be used herein to describe various orientations, actions, steps, elements, or the like, but the orientations, actions, steps, or elements are not limited by these terms. These terms are only used to distinguish one direction, action, step or element from another direction, action, step or element. For example, the first feature information may be the second feature information or the third feature information, and similarly, the second feature information and the third feature information may be the first feature information without departing from the scope of the present application. The first characteristic information, the second characteristic information and the third characteristic information are characteristic information of the distributed file system, but are not the same characteristic information. The terms "first", "second", etc. are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "plurality", "batch" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

The terms and abbreviations used in the following examples have the following meanings:

multipath effect (multipath effect): after electromagnetic waves are propagated through different paths, the time for each component field to reach a receiving end is different, and the component fields are mutually superposed according to respective phases to cause interference, so that the original signals are distorted or errors are generated. For example, the electromagnetic wave propagates along two different paths, and the lengths of the two paths are different by exactly half a wavelength, so that the two paths of signals exactly cancel each other when reaching the end point (the peak and the trough coincide). This phenomenon is often encountered during previous viewing of analogue television signals, and when the signal is poor during viewing, a ghost image is seen on the screen because the used signal forms a virtual image slightly to the right as the electron gun on the television scans from left to right. Thus, multipath effects are an important cause of fading. Multipath effects have a very serious impact on digital communications, radar optimum detection, etc.

TA Path: the mobile terminal reports MR data to the base station every moment, and the MR data comprises transmission delay TA, namely Timing Advance and time Advance. In mobile communication, signals are transmitted in space with delay, if a mobile terminal moves away from a base station in a calling period, the signals transmitted from the base station arrive at the mobile station in a mode of being delayed, and meanwhile, the signals of the mobile station also arrive at the base station in a mode of being delayed, and the delay is too long, so that the signals received by the base station in the current time slot of the terminal and the time slots for the base station to receive the signals of other mobile stations are overlapped, and intersymbol interference is caused, therefore, a measurement report head transmitted by the mobile station to the base station carries a time delay value measured by the mobile station in the calling period, and the base station has to monitor the time of call arrival and transmit an instruction to the mobile station on a downlink channel at a frequency of 480ms once to indicate the time of early transmission of the mobile station. The TA represents the transmission delay from the terminal to the base station to be measured, and when the position of the mobile terminal moves, the TA changes.

Example one

The present embodiment provides a terminal positioning method based on an azimuth, which is suitable for positioning a user terminal under an islanding condition, and as shown in fig. 1, the method specifically includes the following steps:

s101, MR data reported by a terminal is obtained, wherein the MR data comprises a service cell ID.

S102, determining the position of the base station according to the work parameter information of the service cell, wherein the work parameter information comprises an adjacent cell ID.

Optionally, the MR data reported by the user terminal only includes the local cell ID and does not include the neighboring cell ID, so that the step further needs to perform neighboring cell ID information backfilling to complete the obtained reported data, and determine whether the serving base station is an islanding station according to the total number of the backfilled neighboring cell IDs and the serving cell IDs.

In another example, the cells of the base station a have a1, a2, A3, the cells of the base station B have B1, B2, B3, the neighboring cell IDs obtained by the server are a1, a2, A3, it is indicated that the serving cell does not have a non-co-located neighboring cell, it is determined that the MR data is an islanding station MR, the base station a is an islanding station, and at this time, the positioning algorithm provided by the present invention is started.

In an example, after the MR data reported by the user terminal is backfilled with the neighboring cell ID, the neighboring cell IDs included are a1, a2, and B1, which indicate that the serving cell has a non-co-located neighboring cell, which indicates that the user terminal can receive signals of multiple base stations at the location, and is not an islanding station, and then other algorithms are used for positioning, such as fingerprint positioning, triangulation positioning, and the like.

S103, judging the total number of the service cell and the adjacent cell.

And S104, if only one is available, determining the terminal position according to the base station position, the first azimuth angle theta of the service cell and the TA path.

The positioning algorithm for the islanding station introduced in this embodiment is divided into two scenarios, namely, a co-located neighbor scenario and a non-co-located neighbor scenario, where the MR data obtained in the foregoing steps includes a cell ID, and if the mobile terminal can only receive a signal of a serving cell, the situation is that there is no co-located neighbor scenario.

In the step, the terminal has no adjacent cell of the same station, the position of the base station matched with the ID of the service cell in the working parameters is determined through the ID information of the service cell in the MR data reported by the terminal, and the azimuth angle of the service cell can be determined through acquiring the working parameters of the base station.

The serving cell acquires the signal transmission delay of a wireless signal transmitted from a base station to a user terminal as TA, the TA multiplied by the electromagnetic wave propagation speed is equal to the linear distance between a user and the base station, and in a suburb with insignificant multipath effect, the linear distance is the radius of the signal range of the base station. And multiplying the signal transmission delay TA by the propagation speed of the electromagnetic wave, wherein the TA path is the radius of the coverage range of the base station signal. And positioning the terminal by using a preset algorithm based on the position of the base station, the first azimuth angle theta of the service cell and the TA path.

S105, if the total number is at least two, determining the position of the terminal according to the position of the base station, the first signal strength and the second azimuth angle alpha of the serving cell, the second signal strength and the third azimuth angle beta of the strongest neighbor cell of the same station of the serving cell and the TA path.

If the mobile terminal can receive signals of two or more cells, the cell is a cell with the same station. The step uses a preset algorithm to position the terminal based on the base station position, the first signal strength of the serving cell, the second azimuth angle alpha, the second signal strength of the strongest co-sited cell of the serving cell, the third azimuth angle beta and the TA path.

The positioning is carried out by using the azimuth angle, and the positioning precision is improved in the regions with rare base stations such as the edges of urban areas.

Example two

In this embodiment, a calculation method for positioning when only one cell signal and multiple cell signals exist in a single base station is refined on the basis of the above embodiment, as shown in fig. 2, the method specifically includes the following steps:

s201, MR data reported by a terminal is obtained, wherein the MR data comprises a service cell ID.

S202, determining the position of the base station according to the work parameter information of the service cell, wherein the work parameter information comprises the ID of the adjacent cell.

S203, the total number of the service cell and the adjacent cell is judged.

S204, if there is only one total, the base station position coordinates (X1, Y1), and the terminal position (X2, Y2) are: x2 is X1+ TA route × cos θ, and Y2 is Y1+ TA route × sin θ.

As shown in fig. 3, if the circle O is drawn by taking the base station position (X1, Y1) of the serving cell receiving the signal as the center O and the TA path as the radius, in this embodiment, if the cell base station position is (X1, Y1) and the terminal position is (X2, Y2), the coordinates may be longitude and latitude, grid dimension coordinates, or coordinates of a plane coordinate system or a spherical coordinate system with an arbitrary preset position as the origin.

And if the TA path is the signal transmission delay × the electromagnetic wave propagation speed, the position of the terminal is necessarily located at the positioning position of the intersection calculated based on the positioning position of the serving cell, which is the first position of the terminal.

As shown in fig. 3, based on the first embodiment, the TA path is equivalent to the line of sight, so the user position should be at a certain point on the circle O, and meanwhile, the cell primary coverage is within 120 degrees of the direction of the base station antenna facing the azimuth, the included angle direction between the line segment OA and the line segment OB is the coverage of the serving cell, and the user position should be on the arc AB in the coverage direction of the serving cell.

As shown in fig. 3, in the case of no co-located neighbor cell, the user may only receive the signal of the serving cell 1, but no neighbor cell signal, and when the user is close to a, the user may receive the signal of the neighbor cell 3 (the coverage of the signal of the neighbor cell is arc AC); and when approaching B, the user may receive the signal of the neighboring cell 2 (the signal coverage of the neighboring cell is arc CB). The specific location of the user should therefore be at the midpoint position P of the arc AB in the coverage direction of the serving cell 1, i.e. the intersection of the serving cell azimuth line and the above-mentioned circle O.

As shown in fig. 3, through mathematical relationships, X2 ═ X1+ TA route × cos θ, and Y2 ═ Y1+ TA route × sin θ.

S205, if the total number is at least two, the base station position coordinates (X1, Y1) are: x3 ═ X1+ TA path × cos [ α + (β - α) × second signal strength |/(| first signal strength | + | second signal strength |) ], Y3 ═ Y1+ TA path × sin [ α + (β - α) × | second signal strength |/(| first signal strength | + | second signal strength |) ]).

As shown in fig. 4, when the user can receive signals of other cells in the same station in addition to the signal of the serving cell, it indicates that the user is located closer to the base station, or the user is located in an area covered by the overlapping signal sectors of two adjacent serving cells (in the same station or in different stations). Since the embodiment is suitable for the situation that the user communicates with the island station, the user may only be in the overlapping coverage range of the adjacent cell of the same station, and there may be more than one adjacent cell.

Fig. 4 is a schematic diagram of one embodiment in a neighboring cell scenario. The TA path is equivalent to the line of sight, the user position should be at a certain point on the circle O, and at the same time, based on the antenna coverage of the serving cell, the user position is most likely to be on the arc between the serving cell 1 and the opposite direction of the cell 2 with the strongest signal. As shown in the figure, cell 1 is a serving cell, cell 2 is a co-sited neighboring cell with the strongest signal, OD is an azimuth line of cell 1, and OE is an azimuth line of cell 2. The most likely position Q for the user is between the circular arcs ED.

Meanwhile, the user position is also reflected in the strength of the signal of the neighboring cell, and the stronger the signal of which cell is received by the user, the closer the user position should be to the cell. The step acquires MR data reported by the base station, where the MR data includes a first signal strength RSRP1 of the serving cell and a second signal strength RSRP2 of the strongest neighbor cell of the same station. As shown in fig. 4, if the second azimuth angle of the serving cell is α and the third azimuth angle of the strongest neighbor cell of the same station is β, the angle θ between the connecting line OQ of the user position Q and the circle center O and the north direction is α + (β - α) × | the second signal strength |/(| the first signal strength | + | the second signal strength |). It should be noted that the angular relationship between the user position and the cell also includes various implementation manners, and in addition to the illustration described in this embodiment, in practical application, based on the number of cells and mathematical relationship, the included angle θ between the line OQ connecting the user position Q and the circle center O and the due north direction has different calculation manners and value results.

After the angle θ is determined, similarly to the above embodiment, assuming the base station position coordinate O (X1, Y1), the terminal position coordinate Q (X3, Y3) is:

In this embodiment, a positioning algorithm of the user terminal when only a single cell signal exists is determined based on the base station location, the first azimuth angle θ of the serving cell, and the TA path, and a positioning algorithm of the user terminal when based on the base station location, the first signal strength of the serving cell, the second azimuth angle α, the second signal strength of the strongest co-located cell of the serving cell, the third azimuth angle β, and the TA path. According to the embodiment, different positioning methods are respectively determined for the single-cell signal and the multi-cell signal in the island station, and the positioning accuracy of the terminal is improved.
