Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a schematic flow chart of a screening method for a WLAN station to be established according to an embodiment of the present invention. The method comprises the following steps: 101, screening out a hot point CI area with data flow reaching a preset value; 102, dividing the hot spot CI region into grids with preset sizes; 103, calculating signal quality parameters of the relevant service cells of the grid and the relevant service cells of the grid; 104, analyzing the acquired MR to obtain a signal quality parameter of the related service cell of the MR and a signal quality parameter of the related service cell of the MR; 105, determining the MR matched with the grid based on the signal quality parameters of the relevant serving cells of the grid and the signal quality parameters of the relevant serving cells of the MR and the relevant serving cells of the MR; 106, calculating the effective user number of the main coverage cell of the grid according to the MR matched with the grid; and 107, screening the grids serving as the WLAN stations to be built according to the effective number of users of the main coverage cells of the grids.
In step 101, because the WLAN station is usually established at a place with high data traffic, the step first screens the cells with data traffic reaching a preset value to determine the hot spot CI area.
In this step, the dual high areas of high voice service and high Data service in the network can be screened out as hot spot CI areas through network load (such as the number of users, the size of uplink and downlink traffic, etc.) and performance indexes of the network (such as per-line traffic volume, PDCH (Packet Data Channel) multiplexing degree, etc.); the areas with the congestion degree reaching a preset threshold and the traffic service reaching the preset threshold can be screened out, the areas are subjected to service analysis to obtain the traffic service occupation ratio in the areas, and the areas with the preset number in the front are selected as the hot spot CI areas according to the sequence of the occupation ratio from high to low; the performance and the system of the resident terminal in the selected area can be analyzed, and whether the occupation ratio of the WLAN supporting terminals in the area can reach a preset ratio or not is determined; and analyzing the network resource configuration condition (such as how many carrier frequencies are configured) of the area screened by the method, and further determining the hot spot CI area by adopting other shunting means (such as cell splitting, capacity expansion and the like) to shunt or not. In this step, the hot spots CI can be screened by combining the above methods.
In step 102, the hot spot CI region is divided into grids to divide the cell into smaller regions, and the hot spots for WLAN station establishment are screened by using the grids smaller than the cell as a unit, so as to improve the accuracy of screening the hot spots for WLAN station establishment. The preset size may be set based on actual requirements, for example, the hot spot CI area is accurately divided into 100m × 100m grids according to a full-network map.
In step 103, the base station in the network may be corresponded to the divided grid according to the latitude and longitude information of the base station, the latitude and longitude of the center point of the grid is taken as the coordinate of the grid, and the signal quality parameters of the relevant serving cell of the grid and the relevant serving cell of the grid are calculated according to the distance between the grid and the base station and the relevant parameters of the base station.
In step 104, MR data may be acquired through an Abis (an Abis interface is defined as a communication interface between a base station controller of a base station subsystem and a base transceiver station) interface in this step, and then the acquired MR is decoded to obtain data recorded in the MR, and the data recorded in the MR may determine signal quality parameters of a relevant serving cell of the MR and a relevant serving cell of the MR.
It should be noted that, in step 103 and step 104, the relevant serving cell includes a main serving cell and a neighboring serving cell, and the signal quality parameter of the relevant serving cell includes a signal strength of the main serving cell and a signal strength of the neighboring serving cell. The primary serving Cell and the neighboring serving Cell may be a primary serving Cell Identifier and a neighboring serving Cell Identifier, for example, CGI (Cell Global Identifier) of a grid corresponding to the primary serving Cell and CGI of a grid corresponding to the neighboring serving Cell.
Specifically, the CGI of the primary serving cell corresponding to the MR, the signal strength of the primary serving cell corresponding to the MR, and the signal strength of the neighboring serving cell corresponding to the MR can be directly determined by data recorded in the MR. The CGI of the neighboring serving cell corresponding to the MR can be obtained by combining the OGL (initial geographic information List), the OFL (initial Frequency List), and the ONL (initial neighbor List) with the current network parameters according to BCCH (Broadcast Control Channel) and BSIC (Base Station Identity Code) recorded in the MR. CGI is a concatenation result of LAC (Location Area Code) and Cell ID (Identifier), and is an integer with a maximum of 10 bits. Wherein, the OGL is a cell geographic information table, the OFL is an initial frequency configuration table, the ONL is an initial neighbor area table, fields in the ONL, the OFL and the OGL are extracted to form a neighbor area table (maximum 64 neighbor areas) of the main service cell, the neighbor area table comprises fields of CGI, BCCH, BSIC, LAT (Latitude), LONG (longitude) and base station altitude (ant Height), and the BCCH and BSIC in the neighbor area table after the BCCH and BSIC in the MR are combined with each other are matched, so that the CGI of the neighbor cell is determined.
It should be noted that, when it is determined that the MR corresponds to the neighboring serving cell, if at least six neighboring serving cells can be determined from the data recorded in the MR, six neighboring serving cells with the strongest signal strength are selected from the six neighboring serving cells as the MR; if less than six neighbor cells can be determined from the data recorded in the MR, the determined neighbor cells are all the neighbor cells of the MR.
Similarly, when the adjacent service cells of at least six grids are determined, six adjacent service cells with the strongest signal strength are selected as the grid; and if the number of the determined adjacent service cells is less than six, the determined adjacent service cells are all used as the adjacent service cells of the grid.
In step 105, the signal quality parameters of the relevant serving cell and the relevant serving cell of the grid and the signal quality parameters of the relevant serving cell of the MR and the relevant serving cell of the MR are matched, and if the parameters of the MR and the grid can be matched, the MR is determined as the MR matched with the grid.
In step 106, the number of effective users of the primary coverage cell in the grid is calculated based on the MR matching the grid, and the grid heat is determined by the number of effective users. Because each MR has a corresponding IMSI (International Mobile Subscriber identity) information, the user corresponding to the MR can be determined from the IMSI information, and thus the Number of users can be determined.
In step 107, the hot degree of the grid can be determined based on the number of effective users of the main coverage cell of the grid, so that the hot spot grid can be screened out, and the screened hot spot grid can be used as the grid of the WLAN station to be established.
In the embodiment of the invention, after the hot spot CI region with the data flow reaching the preset value is screened out, the grid division is carried out on the hot spot CI region, and then the screening of the WLAN station building hot spot is carried out by taking the grid as a unit, so that the screening precision of the WLAN station to be built is improved; determining the MR matched with the grid based on the signal quality parameters of the relevant service cells of the grid and the signal quality parameters of the relevant service cells of the MR and the relevant service cells of the grid, further calculating the effective user number of the main coverage cells of the grid according to the MR matched with the grid, and accurately reflecting the number of users in each grid and the network using condition of the users, thereby screening the grid serving as the WLAN site to be built based on the accurate user number and improving the screening accuracy of the WLAN site to be built; in addition, the method and the device do not need manual participation and a large amount of equipment for field investigation, can automatically and accurately screen out the hot spot of the WLAN station building, have simple operation and reduce the consumed time and resources.
It is understood that the specific manner of implementing step 103 may include: 1031, calculating the signal intensity of the relevant service cell of the grid based on the parameters of the base station corresponding to the grid; 1032, determining a cell with the largest signal strength in the signal strengths of the relevant service cells of the grid as a main service cell of the grid; 1034, determining the cells except the main serving cell of the grid in the relevant serving cells of the grid as the neighboring serving cells corresponding to the grid.
The parameters of the base station corresponding to the grid can be obtained through the data of the network during network establishment, including the antenna height, the antenna azimuth angle and the antenna pitch angle in the base station, the transmission power of the signal, and the like.
Specifically, in step 1031, the loss value of each grid reception level may be calculated by an Okumura-Hata model (the most extensive model is used when the Okumura-Hata model predicts urban signals), and the formula for calculating the path loss according to the Hata-Okumura model is as follows:
Lb＝69.55+26.16lgf-13.82lghb-α(hm)+(44.9-6.55lghb)lgd (1)
in formula 1, hm represents the effective height of the base station antenna (unit: meter), α (hm) represents the height factor of the base station antenna (unit: dB), f represents the working frequency of the base station (unit: MHz), hb represents the effective height of the base station antenna (unit: m), d represents the distance between the center point of the grid and the base station (unit: km), and Lb represents the median of the propagation loss of the quasi-smooth terrain wave in the urban area (unit: dB). Wherein α (hm) can be calculated by α (hm) ═ 3.2[ lg (11.75hm) ]2-4.97, and d can be calculated according to the longitude and latitude of the center point of the grid and the longitude and latitude of the position of the base station.
The loss value Lb of the reception level of each grid can be calculated by the above formula 1, and the signal strength of each cell received by each grid can be calculated by combining the transmission power of the base station signal of each cell.
After calculating the signal strength of each relevant serving cell received by each grid in step 1031, the cell with the largest signal strength is determined, that is, the main serving cell of the grid, and other relevant serving cells are neighboring serving cells of the grid.
It can be understood that, in the embodiment of the present invention, step 105 may employ a maximum difference coefficient algorithm, to match signal quality parameters of the serving cells related to the grid and the serving cells related to the grid with signal quality of the serving cells related to the MRs, and accurately project each MR into the corresponding grid based on a matching result, and perform longitude and latitude identification on the MRs by using longitude and latitude information of a center point of the grid, where the signal strength of the serving cell related to each grid forms a vector as an unknown vector to be compared, and the signal strength of the serving cell related to each MR forms a vector as an ascertained standard vector, and the detailed algorithm is as follows.
Let x and y be the unknown vector to be compared and the known standard vector, respectively. First, a "relative error vector" is defined as:
then, the vector λ is calculatediThe sequences from large to small are recombined: λ ═ λi≥λjI < j, and taking out vector lambdaiThe first k values of (c): xi ═ λ1，λ2，λ3…λk}; finally, the vector ξ is weighted-averaged to obtain the maximum dissimilarity coefficient:
maximum coefficient of dissimilarity ZyHas a value range of [0, ∞), ZyThe smaller the vector is, the more similar the two vectors are, and if and only if Z isyWhen 0, both vectors are identical, i.e. when Z isyWhen the number equals zero, and the MR and the grid match successfully, the MR can be classified as a matching grid.
It should be noted that the K value refers to a count value of valid data items analyzed by the MR, and is dynamic data, and how much valid data is analyzed. The method comprises the steps of analyzing the local cell, the adjacent cells and the like, for example, analyzing the dimensionality of MR table structures such as the signal strength and the quality of 1 adjacent cell in total, analyzing 5 dimensionalities, taking 5 for K, analyzing multiple dimensionalities of multiple adjacent cells in total, and taking how many dimensionalities are analyzed in total.
Fig. 2 is a schematic flow chart of the method for screening a WLAN station to be built shown in fig. 1, where the number of effective users of a grid is calculated. As shown in fig. 2, a specific manner of implementing step 106 may include: 1061, calculating an effective MR with the received signal level greater than a preset threshold in the MRs matched with the grids; 1062, determining the cell to which the valid MR belongs; 1063, using the cell with the largest number of effective MRs as the primary coverage cell of the grid; 1064, determining the number of users corresponding to the valid MRs included in the primary coverage cell of the grid as the number of valid users of the primary coverage cell of the grid.
If the valid MR is an MR whose received signal level Rxlev is greater than the preset threshold, it is determined whether the received signal level recorded in the MR matched with the grid is greater than the preset threshold. Furthermore, the MR usually records the received signals of a plurality of relevant cells, and determines the cell to which the effective MR belongs by judging the cell to which the received signal level of the effective MR is greater than a preset threshold, so as to determine the number of effective MRs belonging to each cell in the grid. After the number of the effective MRs belonging to each cell in the grid is determined, the cell with the largest number of the effective MRs is used as a main coverage cell of the grid, and the number of users corresponding to the effective MRs in the main coverage cell is the effective user number of the main coverage cell of the grid.
It should be noted that, in the embodiment of the present invention, whether the received signal level in the MR is greater than the preset threshold is determined to be an effective MR, and then the user corresponding to the effective MR is an effective user.
Further, in the embodiment of the present invention, the MR in the time period corresponding to the geographic attribute may be obtained based on the geographic attribute of the grid. According to the mobility of users, the number of MRs acquired at different time ends is different under different geographic positions of the grid, for example, the geographic positions can include office areas (office buildings, political offices, industrial parks, hospitals, enterprises and public institutions, scenic spots), residential areas (high-rise residential areas, low-rise residential areas, urban-middle villages, villages and villages), business centers (exhibition centers, long-distance bus stations, train stations and airports), schools (colleges and universities, middle and primary schools), others (leisure and entertainment centers, hospitals and the like), and the like, and the mobility of users at different time periods is greatly different. To acquire more comprehensive data, it is necessary to acquire MRs within a suitable time period based on the geographical location of the grid. For example, for an office area, the user may choose to use 9 a.m.: 00-12: 00 and 2 in the afternoon: 00-6: 00 to acquire MR; for residential areas, the night 19 can be selected: 00-23: 00 to acquire MR; for the business center one can choose to use 8: 00-22: 00 to acquire MR; for a college 7: 00-day 1: 00 to acquire MR; for other regions the time of day may be used to acquire MR. On the basis of the time periods selected for different geographic positions, in order to avoid omission, the number variation trend of the MRs in each grid can be analyzed, and several time periods (for example, 6 time periods) with the highest number of the MRs are selected for MR acquisition.
Fig. 3 is a schematic flowchart of screening a grid serving as a WLAN station to be built in the screening method for a WLAN station to be built shown in fig. 1. As shown in fig. 3, the specific implementation manner of step 107 may include: step 1071, calculating the total number of users corresponding to the valid MR in the MR matched with the grid; step 1072, determine the grid with the maximum ratio of the effective number of users in the main coverage cell to the total number of users as the grid of the WLAN station to be established.
The total number of users corresponding to the effective MR can be calculated based on the effective users of the grid calculated in step 1061, then the ratio of the number of effective users in each grid primary coverage cell to the total number of users is calculated, and the grid with the largest ratio is determined as the grid of the WLAN station to be established.
It should be noted that, the MR matched with the grid may include a situation that multiple MRs correspond to one user, and if the pair MRs corresponding to one user are all valid MRs, a situation that one user is counted as multiple different users may occur, so that a result of calculating valid users is inaccurate, so that before the embodiment of the present invention is executed, the MRs corresponding to the same user in the grid may be kicked, or the valid users may be kicked after the valid users are calculated, so as to ensure accuracy of calculation. In the embodiment of the present invention, the parameters required for the execution in steps 1071 and 1072 may be calculated by the steps of the method shown in fig. 2.

The steps 101-107 included in the method shown in fig. 4 are substantially the same as the steps 101-107 included in the method shown in fig. 1, except that after the step 107, the method further includes: 108, calculating the purity of the grid of the WLAN station to be built; and 109, determining the priority for building the WLAN hot spot based on the value of the purity.
The purity of the grid reflects the purity of signals in the grid, the lower the purity of the grid is, the lower the customer perception is, and the higher the purity of the grid is, the better the customer perception is. The method and the device determine the priority of building the WLAN station according to the purity of the grid corresponding to the WLAN station to be built so as to measure the WLAN building urgency and degree and guide the WLAN building, and the lower the purity of the grid is, the higher the priority of building the WLAN station is.
Specifically, the grid purity calculation method is as follows: the effective MR of the primary coverage cell as the grid of the WLAN station to be built is divided by the effective MR as the grid of the WLAN station to be built.
As an alternative embodiment, before step 107, the method may further include step 110 of determining location information of the grid from the MR matched with the grid; step 111 may be further included after step 107, and the position information of the WLAN station to be established is determined according to the position information of the grid of WLAN stations to be established.
In step 110, since the MR matching the grid has been determined, the grid can be located in short-term based on the address information (e.g., latitude and longitude information) in the MR, i.e., the address information of the grid is determined. Thus, after the grid serving as the WLAN station to be established is screened out in step 107, the location information of the WLAN station to be established can be determined based on the address information of the grid.
