Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to illustrate the technical means of the present invention, the following description is given by way of specific examples.
The embodiment of the invention provides a method for determining a user area. With reference to fig. 1, the method comprises:
s101, obtaining information of a base station cell corresponding to each base station in a target area.
In a mobile communication network, a base station typically covers a certain geographical area, which is called a cell, or base station cell. As shown in fig. 2, the base station cell corresponding to each base station is a regular hexagonal area. In the cell, mobile terminals, such as mobile phones, smartwatches, etc., can reliably communicate with the base station in the cell through a wireless channel.
For a target area, if the target area is a city, the information of the base station cells of all base stations in the city is sequentially acquired, and the base station cells corresponding to all the base stations in the city can completely cover the target area.
And S102, dividing the target area into a plurality of continuous but non-overlapping sub-areas according to the information of the base station cell corresponding to each base station, wherein the base stations contained in any two sub-areas are different, and establishing a mapping relation between the identifier of the sub-area and the identifier information of all the base stations in the sub-area aiming at any sub-area.
Exemplarily, the target area is formed by n base station cells corresponding to base stations 1 to n as shown in fig. 2, and optionally, the base station cell corresponding to one or more base stations is taken as a sub-area, for example, the base station cell corresponding to base station 1 is taken as a sub-area, and the base station cell corresponding to base station 2 is taken as a sub-area \8230 \ 8230, and the base station cell corresponding to base station n is taken as a sub-area; for example, two base station cells corresponding to the base station 1 and the base station 2 are used as a sub-area, and two base station cells corresponding to the base station 3 and the base station 4 are used as a sub-area \8230 \ 8230
S103, acquiring the position information of the user.
In the embodiment of the invention, two methods for acquiring the position information of the user are provided.
The first method, determining the position information of the user by obtaining the mobile signaling information of the user and the mobile communication network: the mobile terminal, such as a mobile phone, a smart watch, and the like, communicates with a mobile communication network through a base station, when a user makes a call, sends a message, and other events through the mobile terminal, a large amount of signaling data is generated, and at this time, the mobile communication network records the position information of the user through each piece of mobile signaling information, wherein the position information includes a user identification code, the number of a base station cell, a timestamp of occurrence of a mobile signaling, and the like.
The second method is that the position information of the user is determined through the longitude and latitude information of the user reported by the user: some mobile terminals are equipped with GPS modules, the mobile terminals themselves can obtain the longitude and latitude information of the position of the mobile terminals through the GPS modules, and the longitude and latitude information of users can be obtained through the report of the users.
And S104, determining the sub-area to which the user belongs according to the position information of the user.
When the location information of the user is mobile signaling information generated by communication between the user and a mobile communication network, the embodiment of the invention provides two feasible implementation modes to determine the sub-area to which the user belongs.
In a first mode, as shown in fig. 3, the method includes:
and S1041, acquiring the latest mobile signaling corresponding to the user according to the timestamp information contained in the mobile signaling information, and acquiring the cell identification code information of the base station corresponding to the latest mobile signaling.
S1042, determining the identification information of the base station to which the user is connected according to the cell identity information of the base station corresponding to the latest mobile signaling.
And S1043, determining the sub-area to which the user belongs according to the identification information of the base station to which the user is connected and the mapping relation between the identification of the sub-area and the identification information of all base stations in the sub-area.
Through steps S1041 to S1043, a cell identification code corresponding to a base station to which the user is currently connected may be acquired, and a sub-area to which the cell belongs may be determined according to the cell identification code, thereby determining the sub-area to which the user is currently belonging.
It should be noted that, when a user is located at a boundary of two cells or a boundary of two adjacent cells, a ping-pong handover may occur, as shown in fig. 2, when the user is located in a cell corresponding to a base station 1 and is adjacent to a boundary of two cells corresponding to the base station 1 and the base station 2, because the strength of a radio channel provided by the base station 1 and the base station 2 for the user is similar, or because the traffic of the base station 1 is much higher than the traffic of the base station 2, the user may be handed over back and forth in the two cells in a short time, that is, a ping-pong handover occurs, at which time, the cell of the base station to which the user belongs cannot be determined, and in order to solve this problem, when the location information of the user is mobile signaling information generated by the user communicating with a mobile communication network, the embodiment of the present invention provides a second method for determining a sub-area to which the user belongs, as shown in fig. 4, the method includes:
and S1044, sequencing the mobile signaling information corresponding to the user according to the sequence of the occurrence time from first to last according to the timestamp information contained in the mobile signaling information, and reading three latest mobile signaling, wherein the three mobile signaling are a first signaling, a second signaling and a third signaling in sequence according to the sequence of the occurrence time from first to last.
S1045, acquiring a time difference between the first signaling and the second signaling
Time difference between the second signaling and the third signaling
And a preset time threshold T.
S1046, if
Is less than the preset time threshold T, and
if the time threshold T is smaller than the preset time threshold T, the base station corresponding to the first signaling and the third signaling is a first base station, and the first base station belongs to a first sub-area, and the base station corresponding to the second signaling is a second base station, and the second base station belongs to a second sub-area, it is determined that the sub-area to which the user belongs is the first sub-area.
By the method, the problem that the sub-area to which the user belongs cannot be determined due to ping-pong switching can be effectively avoided.
When the position information of the user is longitude and latitude information of the user, the process of determining the sub-area to which the user belongs according to the position information of the user comprises the following steps: and acquiring boundary information of each sub-region, and determining the sub-region to which the user belongs according to the longitude and latitude information of the user and the boundary information of each sub-region.
Specifically, the obtaining of the boundary information of each sub-region includes: for any sub-region, determining polygons forming the sub-region; and acquiring a linear function corresponding to each edge in the polygon in a preset map coordinate system and the longitude and latitude of each vertex of the polygon to obtain a boundary constraint condition corresponding to the sub-area.
As shown in fig. 5, if a sub-region is composed of two cells corresponding to base stations 1 and 2, the polygon formed by vertices a to J shown in fig. 5 is the polygon corresponding to the sub-region, and the polygon is composed of 10 line segments a to B, B to C \8230, J to a and 10 vertices a to J. In a preset map coordinate system, a linear function corresponding to each line segment and longitude and latitude information of each vertex can be obtained to form a boundary constraint condition of the polygon.
When the longitude and latitude of the user are known, a plurality of sub-areas to which the user belongs can be obtained according to the longitude information of the user and the boundary constraint condition of each polygon, and then one sub-area to which the user belongs is determined according to the latitude information of the user.
Or, according to the latitude information of the user and the boundary constraint condition of each polygon, a plurality of sub-regions to which the user belongs can be obtained, and then according to the longitude information of the user, a sub-region to which the user belongs is determined.
Further, after determining the sub-region to which the user belongs, in order to further analyze the travel behavior of the user, the embodiment of the present invention further provides a method for assigning a semantic label to each sub-region, so as to better mine the travel purpose of the user, including: dividing all interest points in the target area into a plurality of types, wherein the interest points contained in any two types are different; aiming at any sub-region, acquiring all interest points in the sub-region, and sequentially determining the type of each interest point; calculating the ratio of the number of the interest points of each type to the number of all the interest points in the sub-area in sequence to obtain the type with the maximum ratio; and establishing a semantic label for the sub-region, wherein the semantic label is used for expressing the type with the maximum ratio.
POI (Point Of Interest) is a Point Of Interest, which broadly refers to all geographic objects that can be abstracted as points, and each POI contains four-dimensional information, i.e., information such as name, category, longitude, latitude, and possibly also phone numbers, ratings, and the like. POI data can reflect city activity. Due to the fact that the POI data are large in sample size and wide in coverage range, each sub-region can be semantically identified by analyzing and processing the POI data, and the main function of each sub-region can be identified.
Optionally, all the POIs may be classified into five types, namely, residence, work, entertainment, shopping and others, and if the ratio of the number of POIs belonging to a certain type in a sub-region to the number of all POIs in the sub-region is the largest and exceeds a preset ratio, the semantic label corresponding to the type is assigned to the sub-region to indicate the function of the sub-region.
Further, in order to improve the user travel experience, after a user enters a sub-region, optionally, all the interest points belonging to the type corresponding to the semantic tag in the sub-region are pushed to the user according to the semantic tag of the sub-region to which the user belongs.
The embodiment of the invention provides a method for determining a user area, which comprises the following steps: acquiring information of a base station cell corresponding to each base station in a target area; dividing the target area into a plurality of continuous but non-overlapping sub-areas according to the information of the base station cell corresponding to each base station, wherein the base stations contained in any two sub-areas are different, and establishing a mapping relation between the identifier of the sub-area and the identifier information of all the base stations in the sub-area aiming at any sub-area; acquiring position information of a user; and determining the sub-area to which the user belongs according to the position information of the user. By the method, an API (application program interface) of the third-party map does not need to be called in the process of determining the area to which the user belongs each time, so that the cost for determining the area of the user is reduced.
