示例性的,本实施例可以由计算服务器获取网络服务小区的业务数据,根据实际需要,可以通过获取网络服务小区内的所有业务数据对该网络服务小区内所有用户设备的室内业务分部和室外业务分部进行统计;也可以通过获取网络服务小区内特定的一个用户设备的业务数据对特定的一个用户设备的室内业务分部和室外业务分部进行统计;还可以通过获取网络服务小区内一个特定群体的用户设备的业务数据对该特定群体的用户设备的室内业务分部和室外业务分部进行统计。本实施例仅以获取网络服务小区内的所有业务数据对该网络服务小区内所有用户设备的室内业务分部和室外业务分部的统计进行说明,但本实施例对此不进行限制。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.
本发明实施例所述的网络服务小区可以指针对一个地区组网内的所有服务小区,其中地区可大可小,根据网络优化的需要来确定,比如可以是深圳市组网内的所有服务小区,也可以是深圳市的一个区组网内的所有服务小区。本实施例以深圳市的网络优化为例进行说明,其他地区的原理相同。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.
优选的,可以设置一个更新周期,对每一个更新周期内网络服务小区的所有数据分别进行处理,这样可以得到动态的室内外业务数据的门限。更新周期的长短可以根据需要进行设定,例如可以为一天,一周等。本实施例以其中一个周期为例进行说明,本实施例下文所述所有业务数据均指深圳市组网范围内一个更新周期内的业务数据。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.
示例性的,每一个业务数据包含接收信号测量值及定位信息,其中,所述接收信号测量值表示终端实际接收到的基站发送的信号的大小,在不同的应用领域可以用不同的参数表示,例如,通用移动通信系统(Universal MobileTelecommunications System,简称UMTS)中,接收信号测量值可以为接收信号码域(Received Signal Code Power,简称RSCP),在长期演进(Long TermEvolution,简称LTE)技术中,接收信号测量值可以为参考信号接收功率(Reference Signal Receiving Power,简称RSRP),在全球移动通信系统(Global System For Mobile Communications,简称GSM)中,接收信号测量值可以为接收信号电平(Received Signal Level,简称RXLEV)。本实施例以WCDMA技术中的RSCP为例进行说明,但是,本实施例不对本发明应用的技术领域和接收信号测量值代表的具体参数作出限制。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.
定位信息可以包含全球定位系统(Global Positioning System,简称GPS)定位信息,GPS定位的基本原理是根据高速运动的卫星瞬间位置作为已知的起算数据,采用空间距离后方交会的方法,确定待测点的位置。GPS定位的方法是多种多样的,可以根据不同的用途采用不同的定位方法,本实施例对此不作限定。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.
或者,利用到达时间(Time of Arrival,简称TOA)定位方法、到达时间差(Time Difference of Arrival,简称TDOA)定位方法的信息。例如包含至少三个小区到终端的环回时间(Round Trip Time,简称RTT)。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.
其中,TOA的基本原理为,TOA表示终端与小区之间的信号传播时长(RTT/2),无线电波在空气中传播的速度为光速c,因此小区与终端的距离为c*(RTT/2)。利用至少3个小区与终端之间的距离,根据三边定位原理就可以得出终端的位置。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是TOA的改进算法。TDOA仍然采用根据时间估计距离的方式,与TOA不同的是,TDOA表示信号在终端与两个小区之间的传播时长差,根据光速c与终端与两个小区之间的传播时长差的乘积就能得到终端与两个小区的距离之差。因为两点的距离之差等于一个常数,这符合双曲线的特性,利用3个小区可以得到3条双曲线,这3条双曲线的交点就是定位位置(也可只考虑其中的两条双曲线)。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 ).
示例性的,计算服务器可以接收数据采集设备从网络中采集的MR数据,然后根据MR数据获取业务数据。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数据是网络侧获得终端无线信息的重要手段,主要包含两个部分:上行信号信息以及下行信号信息。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.
示例性的,下行信号信息由网络终端测量采集,通过空口的测量报告(Measurement Report)信令上报给数据采集单元;上行信号信息由网络侧的基站收发台(Base Transceiver Station,简称BTS)测量采集并上报给数据采集单元。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数据可以包括RSCP测量值,GPS信息。MR data can include RSCP measurements, GPS information.
因为数据采集单元采集的MR数据来自网络的不同部分,计算服务器可以将同一终端、同一次业务的MR数据进行整理后得到业务数据。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.
业务数据可以以表格或者其他形式进行储存,即可以储存在计算服务器中,也可以储存在其他储存单元以供计算服务器使用。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:根据所述业务数据的定位信息将每一个所述业务数据对应到一个网络栅格;S202: Correspond each of the service data to a network grid according to the location information of the service data;
示例性的,计算服务器可以预先设置网络栅格图并储存网络栅格图数据。参见图3,该网络栅格图将深圳市组网内的区域按照一定比例划分为大小相同的多个网络栅格。其中,网络栅格图数据可以包括每一个栅格的经度和纬度,栅格编号,小区标识号,邻区标识号及每个栅格的接收信号理论值,其中,所述接收信号理论值表示根据传播模型获取的所述网络栅格内的信号的大小,在不同的应用领域可以用不同的参数表示,但是需要和业务数据中的接收信号测量值表示的参数一致,例如,业务数据中的接收信号测量值为RSCP时,接收信号理论值为RSCP理论值,当接收信号测量值为RSRP时,接收信号理论值为RSRP理论值,当接收信号测量值为RXLEV时,接收信号理论值为RSCP理论值。因为本实施例接收信号测量值以UMTS技术中的RSCP为例进行说明的,所以,在本实施例中,接收信号理论值为RSCP理论值,但是,本实施例不对本发明应用的技术领域和接收信号理论值代表的具体参数作出限制。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.
示例性的,所述网络栅格的RSCP理论值为根据传播模型获取的所述网络栅格内的RSCP值。每一个网络栅格归属一个主服务小区,也有相邻小区。可以预先记录每一个主服务小区的RSCP发射值。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.
根据业务数据的定位信息将该业务数据对应到一个网络栅格可以有多种实现方法,示例性的,可以包括: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:
根据每一个业务数据的定位信息确定对应的所述每一个业务数据发生的计算位置坐标;Determining the calculated location coordinates corresponding to each business data occurrence according to the positioning information of each business data;
将每一个所述业务数据发生的计算位置坐标与包含多个网络栅格的网络栅格图中的位置坐标进行匹配,确定每一个所述业务数据对应的网络栅格。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.
示例性的,计算服务器根据每一个业务数据里面的定位定息定位每一个业务数据。Exemplarily, the computing server locates each service data according to the positioning fixed rate in each service data.
GPS定位利用至少4颗卫星信号来确定终端的位置,目前GPS已经能够达到十米以内的定位精度。但是,因为GPS定位依赖于对卫星信号的捕获和接收,而在室内环境下,很难接收到定位卫星的信号,造成GPS定位无法正常使用,所以,优选的,如果业务数据内含有GPS定位信息则利用GPS对业务数据定位,如果业务数据内部没有GPS定位信息,则根据RTT信息利用TOA或者TDOA的方法对业务数据进行定位,得到每一个业务数据的坐标,优选的,业务数据的坐标可以用经纬度表示。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.
示例性的,计算服务器将每一个业务数据的坐标与网络栅格图中坐标进行匹配,确定每一个所述业务数据对应的网络栅格。例如,假设网络栅格图中与业务数据11的经纬度匹配的位置处于第一网络栅格中,则把业务数据11对应到第一网络栅格。参加图4,可以将每一个业务数据作为一个点映射到网络栅格中相应的位置。优选的,可以将每一个网络栅格分别用一个集合表示,每一个网络栅格中一个更新周期内包含的业务数据作为对应的每一个集合的元素,例如,第一网络栅格一个更新周期内的业务数据可以表示为{业务数据11,业务数据12,业务数据13,业务数据14,......},第二网络栅格一个更新周期内的业务数据可以表示为{业务数据21,业务数据22,业务数据23,业务数据24,......},其他网络栅格表示方法相同。当然,也可以将每一个网络栅格中一个更新周期内包含的业务数据进行统计并用列表表示。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:根据无线电波的传播模型,获取所述每一个网络栅格的接收信号理论值;S203: According to the radio wave propagation model, obtain the theoretical value of the received signal of each network grid;
示例性的,本实施例中接收信号理论值为RSCP理论值。Exemplarily, in this embodiment, the theoretical value of the received signal is an RSCP theoretical value.
示例性的,所述网络栅格的RSCP理论值为根据传播模型获取的所述网络栅格内的RSCP值。每一个网络栅格归属一个主服务小区,可以预先记录每一个主服务小区的RSCP发射值。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.
示例性的,计算服务器可以预先设置网络服务小区的传播模型,实际应用中,由于各省、市的无线传播环境千差万别,例如,处于丘陵地区的城市与处于平原地区的城市相比,其传播环境有很大不同,所以两者的传播模型也会存在较大差异。因此,优选的,网络服务小区的传播模型可以结合地形、地貌、建筑物、植被等参数的影响进行确定。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.
例如,传播模型可以为RSCP=RSCP0-[128.1+37.6log10(D)],For example, the propagation model can be RSCP=RSCP 0 -[128.1+37.6log10(D)],
其中,RSCP为理论值,RSCP0为发射值,128.1+37.6log10(D)为路径损耗(Path Loss,简称PL),D为基站和终端的距离,单位为km。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.
根据传播模型,可以获取网络服务小区每一个网络栅格内的RSCP理论值,示例性的,计算其中一个特定的网络栅格的RSCP理论值时,根据网络栅格的编号可以确定网络栅格归属的主服务小区,进而可以得到主服务小区的RSCP0,利用主服务小区的RSCP发射值和主服务小区到该网络栅格的距离D,根据传播模型可以计算得到该栅格的RSCP理论值。另外,根据计算服务器的计算能力和储存能力,每一个网络栅格的RSCP理论值可以预先计算得到并储存,也可以实时计算。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.
根据无线信号的传播原理,信号在空气中的损耗和穿过建筑物的损耗差距比较大,所以,对于相同无线电发信地点和相同的接收地点,室内和室外接收到的信号的RSCP值不同。所以,一个网络栅格内的RSCP理论值与该地区建筑物的穿透损耗制的差可以作为确定室内业务数据和室外业务数据门限的依据。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:选取每一个所述网络栅格内小于对应网络栅格的接收信号理论值的接收信号测量值;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;
优选的,根据设置的更新周期,在每个更新周期内选取所述每一个网络栅格内在对应更新周期内的所有小于所述RSCP理论值的RSCP测量值。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.
以第一网络栅格为例,第一网络栅格在一个更新周期内业务数据表示为{业务数据11,业务数据12,业务数据13,业务数据14,......},据此,可以得到第一网络栅格在一个更新周期内的业务数据中的RSCP测量值,{RSCP11,RSCP 12,RSCP 13,RSCP 14,......},将该集合中RSCP测量值分别与第一网络栅格中的RSCP理论值比较,得到所有比第一网络栅格中的RSCP理论值小的RSCP测量值,同理,可以求取其他网络栅格内所有比对应网络栅格中的RSCP理论值小的RSCP测量值。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.

优选的,根据设置的更新周期,将所述每一个网络栅格内的每个更新周期内的平均值分别减去预设的修正值得到对应的每一个网络栅格的每个更新周期内的RSCP门限值。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.
以第一网络栅格为例进行说明,将计算所得的一个更新周期内所有比第一网络栅格的RSCP理论值小的RSCP测量值的平均值减去预设的修正值得到第一网络栅格在该更新周期内的RSCP门限值。其中,预设的修正值可以为深圳地区的建筑物穿透损耗值,优选的,因为门限值是利用比RSCP理论值小的所有RSCP测量值的平均值减去修正值得到的,所以,该门限值可以小于深圳地区的建筑物穿透损耗值。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.
同理,可以求取其他网络栅格内所有对应网络栅格在该更新周期内的RSCP门限值。Similarly, the RSCP threshold values of all corresponding network grids in other network grids within the update period may be calculated.

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.
例如,若第一网络栅格内所对应的RSCP测量值均不小于所述第一网络栅格内的RSCP理论值,则将所述第一网络栅格内的RSCP理论值减去预设的修正值得到第一网络栅格的RSCP门限值。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.

在本实施例中,步骤S204的方法为:选取每一个所述网络栅格内大于对应网络栅格的接收信号理论值的接收信号测量值;步骤S205的方法为:计算每一个所述网络栅格内大于对应网络栅格的接收信号理论值的接收信号测量值的平均值,分别减去预设的修正值得到对应的每一个所述网络栅格的接收信号门限值;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;
示例性的,根据设置的更新周期,在每个更新周期内选取所述每一个网络栅格内在对应更新周期内的所有大于所述RSCP理论值的RSCP测量值,并分别计算每一个网络栅格内的每个更新周期内的平均值。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 .
以第二网络栅格为例,第二网络栅格在一个更新周期内业务数据表示为{业务数据21,业务数据22,业务数据23,业务数据24,......},据此,可以得到第二网络栅格在一个更新周期内的业务数据中的RSCP测量值,{RSCP21,RSCP22,RSCP 23,RSCP 24,......},将该集合中RSCP测量值分别与第二网络栅格中的RSCP理论值比较,得到所有比第二网络栅格中的RSCP理论值大的RSCP测量值,然后计算所有比第二网络栅格中的RSCP理论值大的RSCP测量值的平均值。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.
同理,可以求取其他网络栅格内所有比对应网络栅格中的RSCP理论值大的RSCP测量值的平均值。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.
相应的,将所述每一个网络栅格内的平均值分别减去预设的修正值得到对应的每一个网络栅格的RSCP门限值。其中,预设的修正值可以为深圳地区的建筑物穿透损耗值。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.
需要说明的是:同理,本实施例中S204-S205也是根据一个网络栅格内所对应的RSCP测量值以及该网络栅格的RSCP理论值确定该网络栅格的接收信号门限值的一种情况,还存在的一种情况是,当一个网络栅格内所对应的RSCP测量值均不大该网络栅格的RSCP理论值时,在这种况下,根据网络栅格内所对应的RSCP测量值以及该网络栅格的RSCP理论值确定该网络栅格的接收信号门限值的方法不需要经过RSCP测量值的计算,只需将该网络栅格内所对应的RSCP测量值全部与该网络栅格的接收信号理论值进行比较,在确定RSCP测量值均不大于该网络栅格的RSCP理论值后,直接将该网络栅格的RSCP理论值减去预设的修正值得到该网络栅格的接收信号门限值。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.
例如,若第三网络栅格内所对应的RSCP测量值均不大于所述第三网络栅格内的RSCP理论值,则将所述第三网络栅格内的RSCP理论值减去预设的修正值得到第三网络栅格的RSCP门限值。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.
本发明实施例利用统计的方法求取比较精确的室内外RSCP门限值,进而区分室内业务数据和室外业务数据,利用上述两种方法均可实现本发明的发明目的,只是达到的精度不同而已。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 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.
其中,获取单元501,用于获取网络服务小区的业务数据,每一个所述业务数据包含接收信号测量值及定位信息;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;
示例性的,获取单元501获取网络服务小区业务数据,根据实际需要,获取单元501可以获取网络服务小区内的所有业务数据以使得计算服务器50对该网络服务小区内所有用户设备的室内业务分部和室外业务分部进行统计;获取单元501也可以获取网络服务小区内特定的一个用户设备的业务数据以使得计算服务器50对特定的一个用户设备的室内业务分部和室外业务分部进行统计;获取单元501还可以获取网络服务小区内一个特定群体的用户设备的业务数据以使得计算服务器50对该特定群体的用户设备的室内业务分部和室外业务分部进行统计。本实施例仅以获取单元501获取网络服务小区内的所有业务数据为例进行说明,但本实施例对此不进行限制。Exemplarily, the obtaining unit 501 obtains the service data of the network service cell.

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.
本发明实施例所述的网络服务小区可以指针对一个地区组网内的所有网络服务小区,其中地区可大可小,根据网络优化的需要来确定,比如可以是深圳市组网内的所有网络服务小区,也可以是深圳市的一个区组网内的所有网络服务小区。本实施例以深圳市的网络优化为例进行说明,其他地区的原理相同。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.
示例性的,每一个业务数据包含接收信号测量值及定位信息;其中,其中,所述接收信号测量值表示终端实际接收到的基站发送的信号的大小,在不同的应用领域可以用不同的参数表示,例如,通用移动通信系统(UniversalMobile Telecommunications System,简称UMTS中,接收信号测量值可以为接收信号码域(Received Signal Code Power,简称RSCP),在长期演进(LongTerm Evolution,简称LTE)技术中,接收信号测量值可以为参考信号接收功率(Reference Signal Receiving Power,简称RSRP),在全球移动通信系统(Global System For Mobile Communications,简称GSM)中,接收信号测量值可以为接收信号电平(Received Signal Level,简称RXLEV)。本实施例以WCDMA技术中的RSCP为例进行说明,但是,本实施例不对本发明应用的技术领域和接收信号测量值代表的具体参数作出限制。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.
定位信息可以包含全球定位系统(Global Positioning System,简称GPS)定位信息,GPS定位的基本原理是根据高速运动的卫星瞬间位置作为已知的起算数据,采用空间距离后方交会的方法,确定待测点的位置。GPS定位的方法是多种多样的,可以根据不同的用途采用不同的定位方法,本实施例对此不作限定。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.
或者,利用到达时间(Time ofArrival,简称TOA)定位方法、到达时间差(Time Difference of Arrival,简称TDOA)定位方法的信息。例如包含至少三个小区到终端的环回时间(Round Trip Time,简称RTT)。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.
其中TOA的基本原理为,TOA表示终端与小区之间的信号传播时长(RTT/2),无线电波在空气中传播的速度为光速c,因此小区与终端的距离为c*(RTT/2)。利用至少3个小区与终端之间的距离,根据三边定位原理就可以得出终端的位置。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是TOA的改进算法。TDOA仍然采用根据时间估计距离的方式,与TOA不同的是,TDOA表示信号在终端与两个小区之间的传播时长差,根据光速c与终端与两个小区之间的传播时长差的乘积就能得到终端与两个小区的距离之差。因为两点的距离之差等于一个常数,这符合双曲线的特性,利用3个小区可以得到3条双曲线,这3条双曲线的交点就是定位位置(也可只考虑其中的两条双曲线)。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 ).
示例性的,计算服务器50可以接收数据采集设备从网络中采集的MR数据,然后根据MR数据获取业务数据。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是网络侧获得终端无线信息的主要手段,主要包含两个部分:上行信号信息以及下行信号信息。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.
示例性的,下行信号信息由网络终端测量采集,通过空口的测量报告(Measurement Report)信令上报给数据采集单元;上行信号信息由网络侧的BTS测量采集并上报给数据采集单元。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数据可以包括RSCP测量值,GPS信息。MR data can include RSCP measurements, GPS information.
因为数据采集单元采集的MR数据来自网络的不同部分,计算服务器可以将同一终端、同一次业务的MR数据进行整理后得到业务数据。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.
业务数据可以以表格或者其他形式进行储存,既可以储存在计算服务器中,也可以储存在其他储存单元以供计算服务器使用。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.

示例性的,计算服务器可以预先设置网络栅格图并储存网络栅格图数据。参见图3,该网络栅格图将深圳市组网内的区域按照一定比例划分为大小相同的多个网络栅格。其中,网络栅格图数据可以包括每一个栅格的经度和纬度,栅格编号,小区标识号,邻区标识号及每个栅格的接收信号理论值,其中,所述接收信号理论值表示根据传播模型获取的所述网络栅格内的信号的大小,在不同的应用领域可以用不同的参数表示,但是需要和业务数据中的接收信号测量值表示的参数一致,例如,业务数据中的接收信号测量值为RSCP时,接收信号理论值为RSCP理论值,当接收信号测量值为RSRP时,接收信号理论值为RSRP理论值,当接收信号测量值为RXLEV时,接收信号理论值为RSCP理论值。因为本实施例接收信号测量值以UMTS技术中的RSCP为例进行说明的,所以,在本实施例中,接收信号理论值为RSCP理论值,但是,本实施例不对本发明应用的技术领域和接收信号理论值代表的具体参数作出限制。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.
示例性的,所述网络栅格的RSCP理论值为根据传播模型获取的所述网络栅格内的RSCP值。每一个网络栅格归属一个主服务小区,也有相邻小区。可以预先记录每一个主服务小区的RSCP发射值。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.
对应单元502根据业务数据的定位信息确定该业务数据对应的网络栅格可以有多种实现方法,示例性的,可以包括: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:
根据每一个业务数据的定位信息确定对应的所述每一个业务数据发生的计算位置坐标;Determining the calculated location coordinates corresponding to each business data occurrence according to the positioning information of each business data;

示例性的,对应单元502首先根据每一个业务数据里面的定位定息定位每一个业务数据。Exemplarily, the corresponding unit 502 first locates each service data according to the positioning fixed rate in each service data.
GPS定位利用至少4颗卫星信号来确定终端的位置,目前GPS已经能够达到十米以内的定位精度。但是,因为GPS定位依赖于对卫星信号的捕获和接收,而在室内环境下,很难接收到定位卫星的信号,造成GPS定位无法正常使用,所以,优选的,如果业务数据内含有GPS定位信息则利用GPS对业务数据定位,如果业务数据内部没有GPS定位信息,则根据RTT信息利用TOA或者TDOA的方法对业务数据进行定位,得到每一个业务数据的坐标,优选的,业务数据的坐标可以用经纬度表示。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.
示例性的,对应单元502再将每一个业务数据的坐标与网络栅格图中坐标进行匹配,确定每一个所述业务数据对应的网络栅格。例如,假设网络栅格图中与业务数据11的经纬度匹配的位置处于第一网络栅格中,则把业务数据11对应到第一网络栅格。参加图4,可以将每一个业务数据作为一个点映射到网络栅格中相应的位置。优选的,可以将每一个网络栅格分别用一个集合表示,每一个网络栅格中一个更新周期内包含的业务数据作为对应的每一个集合的元素,例如,第一网络栅格一个更新周期内的业务数据可以表示为{业务数据11,业务数据12,业务数据13,业务数据14,......},第二网络栅格一个更新周期内的业务数据可以表示为{业务数据21,业务数据22,业务数据23,业务数据24,......},其他网络栅格表示方法相同。当然,也可以将每一个网络栅格中一个更新周期内包含的业务数据进行统计并用列表表示。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.

计算模块5032,用于计算每一个所述网络栅格内大于对应网络栅格的接收信号理论值的接收信号测量值的平均值,并分别减去预设的修正值得到对应的每一个所述网络栅格的接收信号门限值。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.
以上两种情况均能确定每一个网络栅格的接收信号门限值,只是得到的精度不同而已。下面以接收信号为RSCP时,以第一种情况为例进行具体说明。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.
示例性的,计算服务器50可以预先设置网络服务小区的传播模型,实际应用中,由于各省、市的无线传播环境千差万别,例如,处于丘陵地区的城市与处于平原地区的城市相比,其传播环境有很大不同,所以两者的传播模型也会存在较大差异。因此,优选的,网络服务小区的传播模型可以结合地形、地貌、建筑物、植被等参数的影响进行确定。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.
根据传播模型,可以获取网络服务小区每一个网络栅格内的RSCP理论值,示例性的,计算其中一个特定的网络栅格的RSCP理论值时,根据网络栅格的编号可以确定网络栅格归属的主服务小区,进而可以得到主服务小区的RSCP发射值,利用主服务小区的RSCP发射值和主服务小区到该网络栅格的距离,根据传播模型可以计算得到该栅格的RSCP理论值。另外,根据计算服务器的计算能力和储存能力,每一个网络栅格的RSCP理论值可以预先计算得到并储存,也可以实时计算。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.
优选的,选取模块5031根据更新单元506设置的更新周期,在每个更新周期内选取所述每一个网络栅格内在对应更新周期内的所有小于所述RSCP理论值的RSCP测量值。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 .
以第一网络栅格为例,第一网络栅格在一个更新周期内业务数据表示为{业务数据11,业务数据12,业务数据13,业务数据14,......},据此,可以得到第一网络栅格在一个更新周期内的业务数据中的RSCP测量值,{RSCP11,RSCP 12,RSCP 13,RSCP 14,......},将该集合中RSCP测量值分别与第一网络栅格中的RSCP理论值比较,得到所有比第一网络栅格中的RSCP理论值小的RSCP测量值,同理,可以选取其他网络栅格内所有比对应网络栅格中的RSCP理论值小的RSCP测量值。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.

优选的,计算模块5032根据更新单元506设置的更新周期,将所述每一个网络栅格内的每个更新周期内的平均值分别减去预设的修正值得到对应的每一个网络栅格的每个更新周期内的RSCP门限值。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.
以第一网络栅格为例进行说明,计算模块5032将计算所得的一个更新周期内所有比第一网络栅格中的RSCP理论值小的RSCP测量值的平均值减去预设的修正值得到第一网络栅格在该更新周期内的RSCP门限值。其中,预设的修正值可以为深圳地区的建筑物穿透损耗值,优选的,因为门限值是利用比RSCP理论值小的所有RSCP测量值的平均值减去修正值得到的,所以,该门限值可以小于深圳地区的建筑物穿透损耗值。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.
同理,可以求取其他网络栅格内所有对应网络栅格在该更新周期内的RSCP门限值。Similarly, the RSCP threshold values of all corresponding network grids in other network grids within the update period may be calculated.
示例性的,若第一网络栅格内所有RSCP测量值均不小于所述第一网络栅格的RSCP理论值,则将所述第一网络栅格的RSCP理论值减去预设的修正值得到第一网络栅格的RSCP门限值。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.
