Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.

Another embodiment of the present invention introduces in detail the method for distinguishing indoor and outdoor business data, referring to Figure 2, including:

S201: Obtain service data of network service cells, each of which includes received signal measurement values and positioning information;

Exemplarily, in this embodiment, the computing server can obtain the service data of the network service cell. According to actual needs, the indoor service divisions and outdoor Statistics can be made by the business segment; it is also possible to make statistics on the indoor business segment and the outdoor business segment of a specific user equipment by obtaining the service data of a specific user equipment in the network service cell; it can also be obtained by obtaining a The service data of the user equipment of a specific group is used to collect statistics on the indoor service segment and the outdoor service segment of the user equipment of the specific group. This embodiment is only described by acquiring all service data in the network service cell to obtain statistics on indoor service segments and outdoor service segments of all user equipment in the network service cell, but this embodiment does not limit this.

The network service cell described in the embodiment of the present invention may refer to all service cells in a regional network, where the region can be large or small, determined according to the needs of network optimization, for example, it can be all service cells in the Shenzhen network , can also be all the serving cells in a district network in Shenzhen. In this embodiment, the network optimization in Shenzhen is taken as an example for illustration, and the principles in other regions are the same.

Preferably, an update period can be set, and all data of the network service cell in each update period are processed separately, so that a dynamic threshold of indoor and outdoor service data can be obtained. The length of the update cycle can be set as required, for example, it can be one day, one week, and so on. This embodiment takes one of the periods as an example for illustration, and all the service data described below in this embodiment refers to the service data within one update period within the scope of the Shenzhen network.

Exemplarily, each piece of service data includes a received signal measurement value and positioning information, wherein the received signal measurement value represents the size of the signal sent by the base station actually received by the terminal, which can be represented by different parameters in different application fields, For example, in the Universal Mobile Telecommunications System (UMTS for short), the received signal measurement value can be the received signal code domain (Received Signal Code Power, RSCP for short). In the Long Term Evolution (LTE for short) technology, the received The signal measurement value can be Reference Signal Receiving Power (RSRP for short), and in Global System For Mobile Communications (GSM for short), the received signal measurement value can be Received Signal Level (Received Signal Level , referred to as RXLEV). This embodiment takes RSCP in WCDMA technology as an example for illustration, however, this embodiment does not limit the technical field of application of the present invention and the specific parameters represented by the measured value of the received signal.

Positioning information can include Global Positioning System (GPS) positioning information. The basic principle of GPS positioning is to determine the point to be measured based on the instantaneous position of the high-speed moving satellite as the known starting data, and the method of resection of the space distance s position. There are various GPS positioning methods, and different positioning methods can be used according to different purposes, which is not limited in this embodiment.

Or, use the time of arrival (Time of Arrival, referred to as TOA) positioning method, time difference of arrival (Time Difference of Arrival, referred to as TDOA) positioning method information. For example, at least three cell-to-terminal round-trip times (Round Trip Time, RTT for short) are included.

Among them, the basic principle of TOA is that TOA represents the signal propagation time (RTT/2) between the terminal and the cell, and the speed of radio waves propagating in the air is the speed of light c, so the distance between the cell and the terminal is c*(RTT/2 ). Utilizing the distances between at least three cells and the terminal, the position of the terminal can be obtained according to the principle of trilateration.

TDOA is an improved algorithm of TOA. TDOA still uses the method of estimating the distance based on time. Unlike TOA, TDOA represents the difference in propagation time between the terminal and two cells. According to the product of the speed of light c and the difference in propagation time between the terminal and the two cells, it is The distance difference between the terminal and the two cells can be obtained. Because the distance difference between two points is equal to a constant, this conforms to the characteristics of the hyperbola, and 3 hyperbolas can be obtained by using 3 sub-districts, and the intersection of these 3 hyperbolas is the positioning position (only two hyperbolas can be considered ).

Exemplarily, the computing server may receive MR data collected by the data collection device from the network, and then obtain service data according to the MR data.

MR data is an important means for the network side to obtain terminal wireless information, and mainly includes two parts: uplink signal information and downlink signal information.

Exemplarily, the downlink signal information is measured and collected by the network terminal, and reported to the data collection unit through the measurement report (Measurement Report) signaling of the air interface; the uplink signal information is measured and collected by the Base Transceiver Station (BTS) on the network side And reported to the data acquisition unit.

MR data can include RSCP measurements, GPS information.

Because the MR data collected by the data collection unit come from different parts of the network, the computing server can sort out the MR data of the same terminal and the same service to obtain service data.

The business data can be stored in tables or other forms, that is, it can be stored in the computing server, and it can also be stored in other storage units for use by the computing server.

S202: Correspond each of the service data to a network grid according to the location information of the service data;

Exemplarily, the computing server may pre-configure the network raster map and store the network raster map data. Referring to FIG. 3 , the network grid diagram divides the area within the Shenzhen network into multiple network grids of the same size according to a certain ratio. Wherein, the network raster map data may include the longitude and latitude of each grid, the grid number, the cell identification number, the neighbor cell identification number and the theoretical value of the received signal of each grid, wherein the theoretical value of the received signal represents The size of the signal in the network grid obtained according to the propagation model can be represented by different parameters in different application fields, but it needs to be consistent with the parameters represented by the received signal measurement value in the business data, for example, the When the measured value of the received signal is RSCP, the theoretical value of the received signal is the theoretical value of RSCP; when the measured value of the received signal is RSRP, the theoretical value of the received signal is the theoretical value of RSRP; when the measured value of the received signal is RXLEV, the theoretical value of the received signal is RSCP theoretical value. Because the measured value of the received signal in this embodiment is described using RSCP in UMTS technology as an example, so in this embodiment, the theoretical value of the received signal is the theoretical value of RSCP. However, this embodiment does not apply to the technical field and application of the present invention. The specific parameters represented by the theoretical values of the received signal are constrained.

Exemplarily, the theoretical RSCP value of the network grid is an RSCP value in the network grid acquired according to a propagation model. Each network grid belongs to a primary serving cell and also has adjacent cells. The RSCP transmission value of each primary serving cell may be pre-recorded.

There are many implementation methods for mapping the service data to a network grid according to the location information of the service data, for example, it may include:

Determining the calculated location coordinates corresponding to each business data occurrence according to the positioning information of each business data;

Matching the calculated location coordinates where each of the service data occurs with the location coordinates in the network grid map containing multiple network grids, to determine the network grid corresponding to each of the service data.

Exemplarily, the computing server locates each service data according to the positioning fixed rate in each service data.

GPS positioning uses at least 4 satellite signals to determine the location of the terminal. At present, GPS has been able to achieve positioning accuracy within ten meters. However, because GPS positioning depends on the acquisition and reception of satellite signals, and in an indoor environment, it is difficult to receive signals from positioning satellites, causing GPS positioning to fail to work normally. Therefore, preferably, if the business data contains GPS positioning information Then use GPS to locate the business data. If there is no GPS positioning information in the business data, then use the TOA or TDOA method to locate the business data according to the RTT information, and obtain the coordinates of each business data. Preferably, the coordinates of the business data can be used Indicates latitude and longitude.

Exemplarily, the calculation server matches the coordinates of each service data with the coordinates in the network grid map, and determines the network grid corresponding to each service data. For example, assuming that the location matching the latitude and longitude of the service data 11 in the network grid diagram is in the first network grid, then the service data 11 is mapped to the first network grid. Referring to Figure 4, each business data can be mapped to the corresponding position in the network grid as a point. Preferably, each network grid can be represented by a set, and the business data contained in each network grid within an update cycle is used as the corresponding elements of each set, for example, the first network grid within an update cycle The business data of the second network grid can be expressed as {business data 11, business data 12, business data 13, business data 14, ...}, and the business data within one update period of the second network grid can be expressed as {business data 21 , business data 22, business data 23, business data 24, ......}, other grid representation methods are the same. Of course, it is also possible to make statistics on the service data included in one update period in each network grid and express it in a list.

S203: According to the radio wave propagation model, obtain the theoretical value of the received signal of each network grid;

Exemplarily, in this embodiment, the theoretical value of the received signal is an RSCP theoretical value.

Exemplarily, the theoretical RSCP value of the network grid is an RSCP value in the network grid acquired according to a propagation model. Each network grid belongs to a primary serving cell, and the RSCP transmission value of each primary serving cell may be pre-recorded.

Exemplarily, the calculation server can pre-set the propagation model of the network service cell. In practical applications, since the wireless propagation environments of provinces and cities vary greatly, for example, the propagation environment of cities in hilly areas is different from that of cities in plain areas. are very different, so the propagation models of the two will also be quite different. Therefore, preferably, the propagation model of the network serving cell can be determined in combination with influences of parameters such as terrain, topography, buildings, and vegetation.

For example, the propagation model can be RSCP=RSCP ₀ -[128.1+37.6log10(D)],

Among them, RSCP is the theoretical value, RSCP ₀ is the transmission value, 128.1+37.6log10(D) is the path loss (Path Loss, PL for short), and D is the distance between the base station and the terminal, in km.

According to the propagation model, the theoretical value of RSCP in each network grid of the network service cell can be obtained. For example, when calculating the theoretical RSCP value of a specific network grid, the ownership of the network grid can be determined according to the number of the network grid The primary serving cell, and then the RSCP ₀ of the primary serving cell can be obtained. Using the RSCP transmission value of the primary serving cell and the distance D from the primary serving cell to the network grid, the theoretical RSCP value of the grid can be calculated according to the propagation model. In addition, according to the computing power and storage capacity of the computing server, the theoretical RSCP value of each network grid can be calculated and stored in advance, or can be calculated in real time.

According to the principle of wireless signal propagation, the loss of the signal in the air and the loss of passing through the building are relatively large. Therefore, for the same radio sending location and the same receiving location, the RSCP values of signals received indoors and outdoors are different. Therefore, the difference between the theoretical value of RSCP in a network grid and the penetration loss of buildings in this area can be used as the basis for determining the threshold of indoor business data and outdoor business data.

S204: Select a received signal measurement value in each of the network grids that is smaller than a theoretical value of the received signal of the corresponding network grid;

Preferably, according to the set update period, all RSCP measurement values smaller than the RSCP theoretical value in each network grid within the corresponding update period are selected in each update period.

Taking the first network grid as an example, the business data of the first network grid is expressed as {business data 11, business data 12, business data 13, business data 14, ...} within an update period, according to , you can get the RSCP measurement value in the service data of the first network grid within an update period, {RSCP11, RSCP 12, RSCP 13, RSCP 14,...}, and the RSCP measurement values in the set are respectively Compared with the theoretical value of RSCP in the first network grid, all RSCP measurement values smaller than the theoretical value of RSCP in the first network grid can be obtained. Similarly, all the ratios in other network grids can be calculated. The theoretical value of RSCP is smaller than the measured value of RSCP.

S205: Calculate the average value of the received signal measurement values in each of the network grids that is smaller than the theoretical value of the received signal of the corresponding network grid, and subtract the preset correction value to obtain the corresponding receiving signal of each of the network grids signal threshold;

Preferably, according to the set update period, the average value in each update period in each network grid is respectively subtracted from the preset correction value to obtain the corresponding value in each update period of each network grid. RSCP threshold.

Taking the first network grid as an example, the first network grid is obtained by subtracting the preset correction value from the average value of all RSCP measurement values smaller than the theoretical RSCP value of the first network grid within an update cycle. The RSCP threshold value of the grid in the update period. Wherein, the preset correction value can be the building penetration loss value in Shenzhen area, preferably, because the threshold value is obtained by subtracting the correction value from the average value of all RSCP measured values smaller than the RSCP theoretical value, so, The threshold value can be smaller than the building penetration loss value in Shenzhen area.

Similarly, the RSCP threshold values of all corresponding network grids in other network grids within the update period may be calculated.

It should be noted that: S204-S205 is a situation in which the received signal threshold value of the network grid is determined according to the corresponding RSCP measurement value in the network grid and the RSCP theoretical value of the network grid. The first case is that when the corresponding RSCP measurement values in a network grid are not smaller than the theoretical RSCP value of the network grid, in this case, according to the corresponding RSCP measurement values in the network grid and the network grid The method of determining the received signal threshold value of the network grid based on the RSCP theoretical value of the network grid does not need to go through the calculation of the RSCP measurement value, but only needs to combine all the corresponding RSCP measurement values in the network grid with the received signal of the network grid. Compared with the theoretical value, after confirming that the measured RSCP values are not smaller than the theoretical RSCP value of the network grid, directly subtract the preset correction value from the theoretical RSCP value of the network grid to obtain the received signal threshold of the network grid value.

For example, if the corresponding RSCP measurement values in the first network grid are not less than the RSCP theoretical value in the first network grid, then subtract the preset RSCP theoretical value in the first network grid The correction value obtains the RSCP threshold value of the first network grid.

S206: Distinguishing indoor service data and outdoor service data of each network grid according to the received signal threshold value of each network grid and the corresponding received signal measurement value corresponding to each network grid;

Exemplarily, after determining the RSCP threshold value of each network grid in a specific update period, the RSCP measurement value of each service data is compared with the RSCP threshold value in the corresponding network grid to determine the Whether the data belongs to indoor service data or outdoor service data.

Preferably, according to the set update cycle, the business data whose RSCP measurement value in each grid network is greater than the RSCP threshold value of the corresponding network grid is counted as outdoor business data in each update cycle, and the statistics in each grid network The service data whose RSCP measurement value is smaller than the RSCP threshold value of the corresponding network grid is regarded as the indoor service data.

S207: Generate an indoor service distribution map and an outdoor service distribution map of the network service cell respectively according to the indoor service data and outdoor service data of each network grid.

Exemplarily, an outdoor service distribution map and an indoor service distribution map within a specific period are drawn respectively according to updating the outdoor service data and the indoor service data within the specific period.

According to the outdoor service distribution diagram and the indoor service distribution diagram in multiple continuous update periods, the trend of service distribution and the indoor service distribution trend can be analyzed respectively.

The method for distinguishing indoor and outdoor business data provided by the embodiment of the present invention uses a statistical method to determine the threshold of indoor and outdoor business data according to the difference between received signals of indoor business data and outdoor business data, and then effectively separates indoor MR data and outdoor MR data come out to realize the separation of indoor hotspots and outdoor hotspots, and then realize the selection of corresponding expansion technologies according to indoor hotspots and outdoor hotspots.

The embodiment of the present invention provides another method for distinguishing indoor and outdoor service data, the main process of which is the same as that of the above embodiment, except that steps S204 and S205 are different, and only the different parts will be described below.

In this embodiment, the method of step S204 is: select the measured value of the received signal in each of the network grids that is greater than the theoretical value of the received signal of the corresponding network grid; the method of step S205 is: calculate the value of each of the network grids The average value of the received signal measurement values greater than the theoretical value of the received signal of the corresponding network grid in the grid, respectively subtracting the preset correction value to obtain the corresponding received signal threshold value of each of the network grids;

Exemplarily, according to the set update period, all RSCP measurement values greater than the RSCP theoretical value in each network grid within the corresponding update period are selected in each update period, and each network grid is calculated separately The average value over each update cycle within .

Taking the second network grid as an example, the business data of the second network grid is represented as {business data 21, business data 22, business data 23, business data 24, ...} within an update cycle, according to , the RSCP measurement value in the service data of the second network grid in an update period can be obtained, {RSCP21, RSCP22, RSCP 23, RSCP 24,...}, and the RSCP measurement value in the set is respectively compared with Compare the theoretical RSCP values in the second network grid to obtain all measured RSCP values greater than the theoretical RSCP value in the second network grid, and then calculate all measured RSCP values greater than the theoretical RSCP value in the second network grid average of.

Similarly, the average value of all measured RSCP values in other network grids that are greater than the theoretical RSCP value in the corresponding network grid can be calculated.

Correspondingly, the average value in each network grid is subtracted from the preset correction value to obtain the corresponding RSCP threshold value of each network grid. Wherein, the preset correction value may be the building penetration loss value in Shenzhen area.

It should be noted that: similarly, S204-S205 in this embodiment is also a part of determining the received signal threshold value of the network grid according to the corresponding RSCP measurement value in the network grid and the RSCP theoretical value of the network grid. In this case, there is also a situation that when the corresponding RSCP measurement values in a network grid are not greater than the theoretical RSCP value of the network grid, in this case, according to the corresponding RSCP in the network grid The RSCP measurement value and the RSCP theoretical value of the network grid to determine the received signal threshold value of the network grid do not need to go through the calculation of the RSCP measurement value, only need to compare all the corresponding RSCP measurement values in the network grid with The received signal theoretical value of the network grid is compared, and after the RSCP measurement value is determined not to be greater than the RSCP theoretical value of the network grid, the network grid is obtained by directly subtracting the preset correction value from the RSCP theoretical value of the network grid. The received signal threshold of the grid.

For example, if the corresponding RSCP measurement values in the third network grid are not greater than the RSCP theoretical value in the third network grid, then subtract the preset RSCP theoretical value in the third network grid. The correction value is used to obtain the RSCP threshold value of the third network grid.

In the embodiment of the present invention, a statistical method is used to obtain relatively accurate indoor and outdoor RSCP threshold values, and then to distinguish between indoor business data and outdoor business data. The purpose of the invention can be achieved by using the above two methods, but the accuracy achieved is different. .

The method for distinguishing indoor and outdoor business data provided by the embodiment of the present invention uses a statistical method to determine the threshold of indoor and outdoor business data according to the difference between received signals of indoor business data and outdoor business data, and then effectively separates indoor MR data and outdoor MR data come out to realize the separation of indoor hotspots and outdoor hotspots, and then realize the selection of corresponding expansion technologies according to indoor hotspots and outdoor hotspots.

An embodiment of the present invention provides a device for distinguishing indoor and outdoor business data. The device can be configured on a computing server 50 and applied to the method shown in FIG. 1. Referring to FIG. 5, the computing server 50 includes: an acquisition unit 501 corresponding A unit 502, a threshold value determining unit 503, and a distinguishing unit 504.

Wherein, the acquiring unit 501 is configured to acquire service data of a network service cell, each of which includes received signal measurement values and positioning information;

Exemplarily, the obtaining unit 501 obtains the service data of the network service cell. According to actual needs, the obtaining unit 501 may obtain all the service data in the network service cell so that the computing server 50 divides the indoor services of all user equipments in the network service cell. Perform statistics with the outdoor business segment; the acquisition unit 501 may also acquire the service data of a specific user equipment in the network service cell so that the calculation server 50 performs statistics on the indoor business segment and the outdoor business segment of a specific user equipment; The obtaining unit 501 may also obtain service data of a specific group of user equipments in the network service cell, so that the calculation server 50 makes statistics on the indoor service segment and the outdoor service segment of the specific group of user equipments. This embodiment is only described by taking the acquisition unit 501 acquiring all service data in the network service cell as an example, but this embodiment does not limit this.

The network service cell described in the embodiment of the present invention can refer to all network service cells in a regional network, where the region can be large or small, determined according to the needs of network optimization, for example, it can be all networks in the Shenzhen network The serving cell may also be all network serving cells in a district network in Shenzhen. In this embodiment, the network optimization in Shenzhen is taken as an example for illustration, and the principles in other regions are the same.

Exemplarily, each service data includes received signal measurement value and positioning information; wherein, the received signal measurement value represents the size of the signal sent by the base station actually received by the terminal, and different parameters can be used in different application fields It means that, for example, in the Universal Mobile Telecommunications System (UMTS for short), the received signal measurement value can be the received signal code domain (Received Signal Code Power, RSCP for short), and in the Long Term Evolution (LTE for short) technology, The received signal measurement value can be Reference Signal Receiving Power (RSRP for short), and in Global System For Mobile Communications (GSM for short), the received signal measurement value can be Received Signal Level (Received Signal Level, referred to as RXLEV). This embodiment takes RSCP in WCDMA technology as an example for illustration, but this embodiment does not limit the technical field of application of the present invention and the specific parameters represented by the measured value of the received signal.

Positioning information can include Global Positioning System (GPS) positioning information. The basic principle of GPS positioning is to determine the point to be measured based on the instantaneous position of the high-speed moving satellite as the known starting data, and the method of resection of the space distance s position. There are various GPS positioning methods, and different positioning methods can be used according to different purposes, which is not limited in this embodiment.

Or, use the time of arrival (Time of Arrival, referred to as TOA) positioning method, time difference of arrival (Time Difference of Arrival, referred to as TDOA) positioning method information. For example, at least three cell-to-terminal round-trip times (Round Trip Time, RTT for short) are included.

The basic principle of TOA is that TOA represents the signal propagation time (RTT/2) between the terminal and the cell, and the speed of radio waves propagating in the air is the speed of light c, so the distance between the cell and the terminal is c*(RTT/2) . Utilizing the distances between at least three cells and the terminal, the position of the terminal can be obtained according to the principle of trilateration.

TDOA is an improved algorithm of TOA. TDOA still uses the method of estimating the distance based on time. Unlike TOA, TDOA represents the difference in propagation time between the terminal and two cells. According to the product of the speed of light c and the difference in propagation time between the terminal and the two cells, it is The distance difference between the terminal and the two cells can be obtained. Because the distance difference between two points is equal to a constant, this conforms to the characteristics of the hyperbola, and 3 hyperbolas can be obtained by using 3 sub-districts, and the intersection of these 3 hyperbolas is the positioning position (only two hyperbolas can be considered ).

Exemplarily, the calculation server 50 may receive MR data collected by the data collection device from the network, and then obtain service data according to the MR data.

MR is the main means for the network side to obtain terminal wireless information, which mainly includes two parts: uplink signal information and downlink signal information.

Exemplarily, the downlink signal information is measured and collected by the network terminal, and reported to the data collection unit through the measurement report (Measurement Report) signaling of the air interface; the uplink signal information is measured and collected by the BTS on the network side and reported to the data collection unit.

MR data can include RSCP measurements, GPS information.

Because the MR data collected by the data collection unit come from different parts of the network, the computing server can sort out the MR data of the same terminal and the same service to obtain service data.

Business data can be stored in tables or other forms, either in the computing server or in other storage units for use by the computing server.

A corresponding unit 502, configured to map each of the service data to a network grid according to the location information of the service data;

Exemplarily, the computing server may pre-configure the network raster map and store the network raster map data. Referring to FIG. 3 , the network grid diagram divides the area within the Shenzhen network into multiple network grids of the same size according to a certain ratio. Wherein, the network raster map data may include the longitude and latitude of each grid, the grid number, the cell identification number, the neighbor cell identification number and the theoretical value of the received signal of each grid, wherein the theoretical value of the received signal represents The size of the signal in the network grid obtained according to the propagation model can be represented by different parameters in different application fields, but it needs to be consistent with the parameters represented by the received signal measurement value in the business data, for example, the When the measured value of the received signal is RSCP, the theoretical value of the received signal is the theoretical value of RSCP; when the measured value of the received signal is RSRP, the theoretical value of the received signal is the theoretical value of RSRP; when the measured value of the received signal is RXLEV, the theoretical value of the received signal is RSCP theoretical value. Because the measured value of the received signal in this embodiment is described using RSCP in UMTS technology as an example, so in this embodiment, the theoretical value of the received signal is the theoretical value of RSCP. However, this embodiment does not apply to the technical field and application of the present invention. The specific parameters represented by the theoretical values of the received signal are constrained.

Exemplarily, the theoretical RSCP value of the network grid is an RSCP value in the network grid acquired according to a propagation model. Each network grid belongs to a primary serving cell and also has adjacent cells. The RSCP transmission value of each primary serving cell may be pre-recorded.

There are many implementation methods for the corresponding unit 502 to determine the network grid corresponding to the service data according to the location information of the service data, for example, it may include:

Determining the calculated location coordinates corresponding to each business data occurrence according to the positioning information of each business data;

Match the calculated location coordinates where each of the service data occurs with the location coordinates in the network grid map containing multiple network grids, and determine the network grid corresponding to each of the service data.

Exemplarily, the corresponding unit 502 first locates each service data according to the positioning fixed rate in each service data.

GPS positioning uses at least 4 satellite signals to determine the location of the terminal. At present, GPS has been able to achieve positioning accuracy within ten meters. However, because GPS positioning depends on the acquisition and reception of satellite signals, and in an indoor environment, it is difficult to receive signals from positioning satellites, causing GPS positioning to fail to work normally. Therefore, preferably, if the business data contains GPS positioning information Then use GPS to locate the service data. If there is no GPS positioning information inside the service data, then use the TOA or TDOA method to locate the service data according to the RTT information, and obtain the coordinates of each service data. Preferably, the coordinates of the service data can be used Indicates latitude and longitude.

Exemplarily, the corresponding unit 502 matches the coordinates of each service data with the coordinates in the network grid map, and determines the network grid corresponding to each service data. For example, assuming that the location matching the latitude and longitude of the service data 11 in the network grid diagram is in the first network grid, then the service data 11 is mapped to the first network grid. Referring to Figure 4, each business data can be mapped to the corresponding position in the network grid as a point. Preferably, each network grid can be represented by a set, and the service data contained in each network grid within an update period is used as the corresponding elements of each set, for example, the first network grid within an update period The business data of the business data can be expressed as {business data 11, business data 12, business data 13, business data 14,...}, and the business data within one update cycle of the second network grid can be expressed as {business data 21 , business data 22, business data 23, business data 24, ......}, other grid representation methods are the same. Of course, it is also possible to make statistics on the service data included in one update period in each network grid and express it in a list.

Threshold value determination unit 503, configured to determine the receiving signal of each of the network grids according to the corresponding received signal measurement value in each of the network grids and the corresponding theoretical value of the received signal of each of the network grids. A signal threshold value, wherein the theoretical value of the received signal of the network grid is the value of the received signal in the network grid acquired according to a propagation model;

A distinguishing unit 504, configured to distinguish the indoor service data of each of the network grids according to the received signal threshold value of each of the network grids and the corresponding received signal measurement value in each of the network grids and outdoor business data.

Further, referring to FIG. 6, the computing server 50 also includes:

An update unit 506, configured to set an update period;

The threshold value determining unit 503 includes:

A selection module 5031, configured to select a received signal measurement value in each of the network grids that is smaller than a theoretical value of the received signal of the corresponding network grid;

The calculation module 5032 is used to calculate the average value of the received signal measurement values smaller than the theoretical value of the received signal of the corresponding network grid in each of the network grids, and subtract the preset correction value to obtain the corresponding Received signal threshold for the network grid.

Alternatively, the selection module 5031 is configured to select a received signal measurement value in each of the network grids that is greater than a theoretical value of the received signal of the corresponding network grid;

The calculation module 5032 is used to calculate the average value of the received signal measurement values greater than the theoretical value of the received signal of the corresponding network grid in each of the network grids, and subtract the preset correction value respectively to obtain the corresponding Received signal threshold for the network grid.

Both of the above two cases can determine the received signal threshold value of each network grid, but the accuracy obtained is different. In the following, when the received signal is RSCP, the first case is taken as an example for specific description.

Exemplarily, the calculation server 50 can pre-set the propagation model of the network service cell. In practical applications, since the wireless propagation environment of each province and city varies greatly, for example, the propagation environment of a city in a hilly area is different from that of a city in a plain area. There is a big difference, so the propagation models of the two will also be quite different. Therefore, preferably, the propagation model of the network serving cell can be determined in combination with influences of parameters such as terrain, topography, buildings, and vegetation.

According to the propagation model, the theoretical value of RSCP in each network grid of the network service cell can be obtained. For example, when calculating the theoretical RSCP value of a specific network grid, the ownership of the network grid can be determined according to the number of the network grid The primary serving cell, and then the RSCP emission value of the primary serving cell can be obtained. Using the RSCP emission value of the primary serving cell and the distance from the primary serving cell to the network grid, the theoretical RSCP value of the grid can be calculated according to the propagation model. In addition, according to the computing power and storage capacity of the computing server, the theoretical RSCP value of each network grid can be calculated and stored in advance, or can be calculated in real time.

Preferably, the selection module 5031 selects in each update period all RSCP measurement values smaller than the RSCP theoretical value in each network grid within the corresponding update period according to the update period set by the update unit 506 .

Taking the first network grid as an example, the business data of the first network grid is expressed as {business data 11, business data 12, business data 13, business data 14, ...} within an update period, according to , you can get the RSCP measurement value in the service data of the first network grid within an update period, {RSCP11, RSCP 12, RSCP 13, RSCP 14,...}, and the RSCP measurement values in the set are respectively Compared with the theoretical value of RSCP in the first network grid, all measured RSCP values smaller than the theoretical value of RSCP in the first network grid can be obtained. RSCP measured value with small RSCP theoretical value.

Preferably, the calculation module 5032 subtracts the preset correction value from the average value in each update period in each network grid according to the update period set by the update unit 506 to obtain the corresponding value of each network grid. RSCP threshold in each update cycle.

Taking the first network grid as an example for illustration, the calculation module 5032 subtracts the preset correction value from the calculated average value of all RSCP measurement values smaller than the theoretical value of RSCP in the first network grid within one update cycle to obtain The RSCP threshold value of the first network grid in the update period. Wherein, the preset correction value can be the building penetration loss value in Shenzhen area, preferably, because the threshold value is obtained by subtracting the correction value from the average value of all RSCP measured values smaller than the RSCP theoretical value, so, The threshold value can be smaller than the building penetration loss value in Shenzhen area.

Similarly, the RSCP threshold values of all corresponding network grids in other network grids within the update period may be calculated.

Exemplarily, if all RSCP measurement values in the first network grid are not less than the RSCP theoretical value of the first network grid, the preset correction value is subtracted from the RSCP theoretical value of the first network grid RSCP threshold to the first grid.

A distribution map generation unit 505, configured to generate an indoor service distribution map and an outdoor service distribution map of the network service cell respectively according to the indoor service data and outdoor service data of each of the network grids.

Exemplarily, after the threshold value determination unit 503 determines the RSCP threshold value of each network grid in a specific update period, the distinguishing unit 504 uses the RSCP measurement value of each service data and the RSCP gate in the corresponding network grid Limit value comparison can distinguish whether each service data belongs to indoor service data or outdoor service data.

Exemplarily, in a specific period, the distinguishing unit 504 counts the service data whose RSCP measurement value is greater than the RSCP threshold value of the corresponding network grid in each grid network as outdoor service data, and counts the RSCP measurement value in each grid network Service data smaller than the RSCP threshold of the corresponding network grid is regarded as indoor service data.

The distribution map generating unit 505 is configured to generate an indoor service distribution map and an outdoor service distribution map according to the indoor service data and the indoor service data respectively.

Exemplarily, an outdoor service distribution map and an indoor service distribution map in a specific period are drawn respectively according to the outdoor service data and the indoor service data in the specific period.
