detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

In the embodiments of the present invention, the term "terminal" refers to a device (device) that provides voice and/or data connectivity to a user, including a wireless terminal or a wired terminal. The wireless terminal may be a handheld device with a wireless connection function, or other processing device connected to a wireless modem, and a mobile terminal that communicates with one or more core networks via a wireless access network. Wireless terminals may be, for example, mobile telephones (or "cellular" telephones) and computers with mobile terminals. As another example, the wireless terminal may also be a portable, pocket, hand-held, computer built-in or vehicle-mounted mobile device. For another example, the wireless terminal may be a mobile station (mobile station), an access point (access point), or a part of user equipment (user equipment, UE for short).

In the embodiment of the present invention, the term "base station" includes but is not limited to a node, a station controller, an access point (AccessPoint, AP for short), or any other type of interface device capable of working in a wireless environment.

In the prior art, generally speaking, the position of the terminal is located by relying on the data collected by the terminal’s built-in sensors, and then the scene where the terminal is located is determined. For the current built-in sensors of the terminal, different brands and different models of terminals The installed sensor models are not uniform, which makes the collected data standards not unique, which leads to low accuracy in terminal scene judgment.

In order to solve the above problems, an embodiment of the present invention provides a method for judging a terminal scene. The flow of the method is shown in FIG. 1 , and the method may include the following steps:

S101. Obtain communication signaling of the terminal within a set time.

Wherein, the communication signaling includes S1-MME interface signaling and S1-U interface signaling of the terminal. The S1-MME interface is the interface between eNB (Evolved Node B, evolved base station) and MME (Mobility Management Entity, mobility management entity), which is used to transmit session management and mobility management information, that is, control plane information. It mainly completes Functions such as wireless access bearer control of the S1 interface, and interface-specific operation and maintenance. The S1-U interface is the interface between the eNB and the S-GW (Serving GateWay, Serving Gateway). A tunnel is established between the eNB and the S-GW to transmit user service data and carry UE Internet access data packets.

S102. Determine, according to the communication signaling within the set time, a cell where the terminal resides within the set time.

In the embodiment of the present invention, S1-MME interface signaling and S1-U interface signaling are collected. Since the cell information in the S1-U interface signaling is incomplete, only the information of the starting and ending cells when the user service is established and disconnected , therefore, it is necessary to obtain the cell information in the process of cell handover and the like from the S1-MME interface signaling. Then above-mentioned step S102 comprises:

Determine the cell information of the S1-U interface signaling according to the cell information of the S1-MME interface signaling;

Determine the cell where the terminal resides according to the cell information of the S1-U interface signaling.

Specifically, after the S1-MME bill and S1-U bill are collected, the S1-MME interface signaling and the S1-U interface signaling of the same terminal are identified through the IMSI, and the user service start time and end time Associate the S1-MME interface signaling with the S1-U interface signaling, and use the ECI (E-UTRAN Cell Identifier, E-UTRAN cell identifier) of the S1-MME interface signaling to identify the S1-U interface signaling in the same period, that is, the S1 -Each communication signaling in the U interface signaling is filled with ECI field according to the corresponding S1-MME interface signaling, so that the S1-U interface signaling can fully reflect the cell occupancy of the terminal in the network within the set time Condition.

S103. If the number of camping base stations to which the camping cell belongs within the set time is not less than three, determine the center of gravity of a polygon with the positions of the camping base stations as vertices.

S104. Using the quantity of communication signaling of the terminal in each resident base station as a weight, adjust the center of gravity of the polygon to obtain position information of the terminal within the set time.

S105. Determine a scene of the terminal at least according to the location information of the terminal.

In the embodiment of the present invention, the communication signaling of the terminal within the set time is obtained. Since the communication signaling includes the information of the cell where the terminal resides, the residence of the terminal within the set time can be determined according to the communication signaling. district. Then, the geographic location of the terminal is determined according to the location of the base station in the cell where it resides. Specifically, if the number of base stations in the cell where the terminal resides within the set time is not less than three, a polygon is formed with the base stations in each cell as vertices, and the center of gravity of the polygon is determined. Since the terminal resides in different cells for different times, the amount of signaling generated is also different. Therefore, it is not accurate enough to determine the position of the terminal only according to the center of gravity of the polygon. In the embodiment of the present invention, the number of communication signaling of terminals residing in each base station is used as a weight value, and the center of gravity of the polygon is adjusted to obtain the position information of the terminal within the set time, that is, the communication of the terminal in a certain residing cell. If there are many signalings, it is considered that the terminal stays in the cell for a longer period of time, and thus the location of the terminal is more biased towards the cell. Finally, according to the location information of the terminal, the scene of the terminal is determined. In the embodiment of the present invention, the communication signaling data of the terminal is used as the basis for determining the terminal location in the process of determining the terminal scene, and the accuracy of terminal scene judgment is improved due to the unification of data source standards. Moreover, the terminal is positioned geographically by using a polygon positioning method, and the determination result of the terminal position is closer to the actual position in the terminal, which further improves the accuracy.

The polygon positioning method in the embodiment of the present invention is mainly to form a polygon with the cells where the terminal resides, each cell being a vertex of the polygon, and then determine the position of the terminal according to the center of gravity of the polygon. Since a cell is an area concept, the positions of the base stations in each cell can be selected as vertices of a polygon. Wherein, according to the ECI identifier in the S1-U interface signaling, the geographic location of the base station in each resident cell can be obtained, which is represented by latitude and longitude and denoted as (X, Y).

In the embodiment of the present invention, the S1-MME interface signaling and the S1-U interface signaling within the set time are obtained, and the ECI in the S1-MME interface signaling is used to backfill the cell information on the S1-U interface signaling, then The S1-U interface signaling can fully reflect the cell occupancy of the user in the network. According to the cell information in the S1-U interface signaling, the location of the base station corresponding to the cell can be found, and the geographic location of the base station in the cell where the terminal has accessed within the set time is obtained, calculated as (x ₁ , y ₁ ), ( x ₂ , y ₂ )...(x _N , y _N ). If the user terminal is in a stationary state within the set time, the position of the terminal is a fixed point; if the user terminal is in a moving state within the set time, in order to facilitate processing, the embodiment of the present invention simplifies the position of the terminal within the set time is a point, and according to the geographic location coordinates of the base station accessed by the terminal within the set time, determine the position coordinates of the terminal within the set time. Depending on the number of base stations in the corresponding cell where the terminal resides, it can be divided into the following situations.

First case:

If the number of the camped-on base station to which the camped-on cell belongs is one within the set time, then determine the location information of the terminal within the set time according to the base station location of the camped-on cell. That is, within a set time (such as 2 minutes), if the terminal is in a cell, it can stay still in the cell or move in the cell, and the terminal will access the corresponding The base station uses the location of the base station as the location of the terminal within the 2 minutes.

Specifically, if the movement track of the terminal within the set time is located in two or more resident cells, and these resident cells share a base station, the position of the base station is still considered to be the position of the terminal within the 2 minutes.

Second case:

If the number of camping base stations to which the camping cell belongs within the set time is two, then after step S102, further include:

determining a midpoint between the two camping base station locations;

Using the quantity of communication signaling of the terminal in the two resident base stations as a weight value, adjusting the position of the midpoint to obtain the position information of the terminal within the set time.

Specifically, the position of the base station residing in cell 1 is denoted as (x ₁ , y ₁ ), and the position of the base station residing in cell 2 is denoted as (x ₂ , y ₂ ), then the midpoint between the two base stations is The location of the terminal can be determined according to the midpoint location. If the terminal stays in one of the two camping cells for a longer period of time, it is considered that the location of the terminal is closer to the cell with the longer residence time. The amount of communication signaling generated in the camped on cell is larger. Therefore, the number of S1-U interface signaling of the terminal in the two cells where the terminal resides can be used as a weight to correct the midpoint position coordinates to obtain the terminal position coordinates. The number of S1-U interface signaling that the terminal resides in cell 1 is denoted as T ₁ , and the number of S1-U interface signaling that the terminal resides in cell 2 is denoted as T ₂ , then the position of the terminal is :

Simplify Equation 2 to obtain the position coordinates of the terminal as:

Specifically, if the number of S1-U interface signaling generated by the terminal in the two cells where the terminal resides is the same, the midpoint between the two base stations is used as the position of the terminal, that is, within the set time, the position of the terminal The coordinates are

The third case:

If the number of resident base stations in the resident cell of the terminal within the set time (such as 2 minutes) is three, each resident cell forms a triangle according to the latitude and longitude position, and the three vertices of the triangle are three resident base stations , denoted as (x ₁ , y ₁ ), (x ₂ , y ₂ ) and (x ₃ , y ₃ ). The geographic location of the terminal is determined according to the position of the center of gravity of the triangle, because the center of gravity is the intersection point of the midlines of the three sides of the triangle, and this point must be located inside the triangle.

Theoretically, since the outer center of the triangle is the center of the circumscribed circle of the triangle, its distance to each apex of the triangle is equal, which is more in line with the location calculation of static user terminals on the live network. However, if the user terminal is in a moving state, the three base stations it passes are likely to be an obtuse triangle, as shown in Figure 2. At this time, the outer center of the triangle is outside the triangle, which does not conform to the actual situation of the user terminal location , therefore, the position of the center of gravity of the triangle is selected to determine the terminal position.

In the plane Cartesian coordinate system, the coordinates of the center of gravity of the triangle are the arithmetic mean of the coordinates of the vertices, that is, the coordinates of the center of gravity of the triangle are

Similar to the principle in the second case, the longer the terminal stays in one of the three resident cells and the more communication signaling the terminal generates in the resident cell, the terminal position is considered to be The closer the location of the base station to the cell to reside on. Therefore, the number of S1-U interface signaling generated by the terminal in cell 1 is denoted as T ₁ , and the amount of S1-U interface signaling generated in cell 2 is denoted as T ₂ . The number of S1-U interface signaling generated in 3 is recorded as T ₃ , and the number of communication signaling T ₁ , T ₂ , T ₃ is substituted into formula 4, and the position of the terminal is corrected to obtain the terminal position coordinates as:

Fourth case:

If the number of resident base stations to which the resident cell of the terminal belongs within the set time (such as 2 minutes) is N, and N is greater than 3, each resident cell forms a polygon according to the latitude and longitude position, and each vertex of the polygon is The location of the base station where each cell resides is denoted as (x ₁ , y ₁ ), (x ₂ , y ₂ )...(x _N , y _N ). Similar to the method in the third case, the geographic location of the terminal can be determined according to the position of the center of gravity of the polygon.

In geometry, for a polygon with uniform quality, the polygon can be divided into multiple triangles, and the center of gravity of the polygon can be determined according to the centers of gravity of the multiple triangles. Divide the polygon into multiple triangles, and find the center of gravity and area of each triangle; as a two-dimensional polygon, use the area of each triangle as a weight, and multiply the coordinates of the center of gravity of each triangle respectively; The average value is divided by the total area of the polygon to get the barycentric coordinates of the polygon.

In the embodiment of the present invention, specifically, the polygon with N vertices is split into N-2 triangles, and all the sides of the polygon are included in the N-2 triangles. Calculate the barycentric coordinates of each triangle according to the calculation method in the third case, and denote it as ( _xi , y _i ). At the same time, the area S _i of each triangle is calculated. The area of a triangle is calculated as follows:

The three vertices A(x _a ,y _a ), B(x _b ,y _b ), and C(x _c ,y _c ) of triangle ABC are arranged counterclockwise, then the area of triangle ABC is:

Let S _always be the total area of this polygon, then the position coordinates (x, y) of the terminal are:

After determining the location of the terminal, the scene of the terminal can be judged according to the motion state of the terminal. Step S105 includes:

Taking the set time as a period, if it is determined that the distance between the position of the terminal in the nth period and the position of the terminal in the reference period is not greater than the distance threshold, the position information of the terminal in the nth period and the The position information of the terminal in the first period is classified into the same group, n is an integer greater than or equal to 2, and the reference period is the first period in each group;

Determine whether the maximum time difference in the same group is greater than the time threshold, if greater than the time threshold, the scene of the terminal is an indoor scene;

Otherwise, the scene of the terminal is an outdoor scene.

Specifically, the position coordinates of the terminal within the set time are determined according to steps S101 to S104, and the set time is used as a period to determine the position coordinates of the terminal in each period. The position of the first cycle of the terminal is used as the reference position, and the position of the next cycle is judged by the distance from the position of the first cycle. If the distance is less than or equal to the distance threshold, such as 200 meters, the position of the next cycle continues to be compared with the reference position. distance judgment. Until the distance from the position of the mth period to the reference position is greater than the distance threshold, the position of the period before the mth period is regarded as a group, and the position of the mth period is used as the reference point of the next group.

For example, if the position of the terminal is calculated every 2 minutes within two hours, then 60 position points of the terminal are calculated. Take the first location point as the reference position of the first group, compare the distance between the second location point and the first location point, and find that the distance is less than 200 meters, put the second location point into the first group , continue to compare the distance between the third location point and the first location point. Until the distance between the fifth position point and the first position point is greater than 200 meters, the fifth position point is used as the reference position of the second group, and then the distance between the sixth position point and the fifth position point is compared . The previous 1st position point to the 4th position point are all the first grouping. If the distance from the 6th location point to the 13th location point to the 5th location point is less than 200 meters, and the distance from the 14th location point to the 5th location point is greater than 200 meters, then the 5th location point Points up to the 13th position are used as the second group, the 14th position is used as the third group, and so on.

Based on the time spent in each group, it is determined whether the scene of the group is indoor or outdoor. Since the time of each location point in the group is 2 minutes, it can be determined whether the time difference between the first location point and the last location point in the same group, that is, the maximum time difference in the group is greater than the time threshold. If it is greater than the time threshold, the group is an indoor scene; otherwise, the group is an outdoor scene.

Further, a more fine-grained scene division may be made for a terminal determined to be an indoor scene or an outdoor scene. After determining whether the maximum time difference in the same group is greater than the time threshold, it also includes:

determining the cell scene of the cell where the terminal resides in each period of the same group;

Add the number of communication signaling of all resident cells in the same cell scene, and use it as the number of communication signaling in the cell scene;

Determining a cell scenario with the largest number of communication signaling among all cell scenarios and exceeding the quantity threshold as the scenario of the terminal.

For a terminal in an indoor scene, by analyzing the communication signaling of the terminal, the basic information of the base station corresponding to the cell can be found according to the basic information of the cell, so as to determine whether the scene where the terminal resides in the cell occupies an indoor or a macro station. In each period of the same group, the quantity of communication signaling occupying the room and the quantity of communication signaling occupying the macro station in the communication signaling of the terminal are determined. Calculate the ratio of the number of communication signaling occupying the room to the total number of communication signaling (ie p+q), denoted as p; calculate the ratio of the number of communication signaling occupying the macro station to the total number of communication signaling, denoted as q. Compare p and q with scene thresholds (for example, 80%). If p is greater than 80%, the terminal scene is an indoor stable scene occupying room points; if q is greater than 80%, then the terminal scene is occupied by a macro station. Indoor stable scene; if both p and q are not greater than 80%, the terminal scene is an indoor stable scene that occupies room points and macro stations.

For the terminals in the outdoor scene, the terminals in the outdoor scene can be further divided into low-speed terminals, medium-speed terminals, or high-speed terminals according to the moving speed of the terminals. The distance that the terminal moves in each cycle can be determined through the previous calculation, and then the displacement per unit time of the terminal can be obtained, which is the speed of the terminal.

After the terminal scene is divided into indoor scene or outdoor scene, and the outdoor scene is divided according to speed, the terminal scene can be further refined into 7 scenes, including: campus scene, residential area scene, and commercial area scene , scenic area scenes, subway scenes and high-speed rail scenes.

According to the basic information of the cell in the communication signaling of the terminal, the corresponding cell scene can be found, and the cell scene to which the cell where the terminal resides in the n periods belongs is determined. The calculation of the number of communication signaling of the terminal in the same cell scene is the sum of the number of communication signaling of all the cells that reside in the cell scene. The cell scenario where the number of communication signaling is the largest and exceeds the number threshold is used as the terminal scenario. For example, the cells where a terminal resides within two hours are cell 1, cell 2, cell 3, and cell 4. The cell scene of cell 1 is a campus scene, and the corresponding number of communication signaling is 5; the cell of cell 2 The scene is a commercial area scene, and the corresponding number of communication signaling is 100; the community scene of community 3 is a residential area scene, and the number of communication signaling is 10; the community scene of community 4 is a campus scene, and the number of communication signaling is 5 . Then, the community scenarios are respectively campus scene, commercial area scene and residential area scene, and the corresponding communication signaling numbers are 10, 100, and 10. Since the number of communication signaling in the commercial area scene is the largest and accounts for more than 80%, the terminal's The scene is a business district scene.

Further, it may be determined that the proportion of a single scene of the terminal is greater than a scene threshold, for example, 80%, it is determined that the terminal is in the scene. Specifically, the judgment method is as follows:

(a) Campus scene: For the three indoor scenes and the low-speed outdoor scene, determine the cell scene of the terminal communication signaling, if more than 80% of the communication signaling occurs in the campus, then determine that the terminal scene is a campus scene.

(b) Residential area scene: For the three indoor scenes and low-speed outdoor scene, determine the cell scene of the terminal communication signaling, if more than 80% of the communication signaling occurs in a residential area, then determine that the terminal scene is a residential area area scene.

(c) Commercial area scene: For the three indoor scenes, determine the cell scene of the terminal communication signaling, if more than 80% of the communication signaling occurs in the commercial area, then determine that the terminal scene is a commercial area scene.

(d) Scenic area scene: For the three indoor scenes and low-speed outdoor scene, determine the cell scene of the terminal communication signaling, if more than 80% of the communication signaling occurs in the scenic area, then determine that the terminal scene is scenic area scene.

(e), subway scene: for three kinds of indoor scenes and three kinds of outdoor scenes, determine the cell scene of the terminal communication signaling, if more than 80% of the communication signaling occurs in the subway, then determine that the terminal scene is a subway scene .

(f) High-speed rail scene: For a high-speed outdoor scene, determine the cell scene of the terminal communication signaling, if more than 80% of the communication signaling occurs in the high-speed rail, then determine that the terminal scene is a high-speed rail scene.

It should be noted that since the location of the terminal can be moved, the scene judgment of the terminal is related to time, that is, the terminal can be an indoor user within the first hour, an outdoor low-speed user within the second hour, and then an outdoor high-speed user.
