As shown in Figure 1, it is a kind of based on the auxiliary network shunt method of grid that present embodiment provides, and comprising:

Step 101, raster data are collected.Grid refers to utilize corresponding signalling analysis platform, and artificial is divided into some continuous grids with a continuous region.Concrete collection method comprises as shown in Figure 2:

Step 1011, collection GB data are collected user's internet records information, and internet records information is carried out 50 * 50 grid location.Gather MR (Measurement Report by the A+Abis platform, measurement report) signaling information, carry out emulation of coverage capability measuring and calculating user's latitude and longitude information in conjunction with longitude and latitude, transmitting power, the urban environment of website, and be positioned to respectively in the grid of 50M * 50M.

Step 1012, collect the TD drive test data from daily TD network optimization group, the drive test data that comprises longitude and latitude of deriving is positioned to 50 * 50 grids.

Step 1013, focus latitude and longitude information and the various performance index of collecting WLAN from operator, and each WLAN focus latitude and longitude information is positioned to 50 * 50 grids.

Step 1014, gather the data in 50 * 50 grids, collected GB data, TD drive test data and WLAN data are gathered at every grid, the GB data are as shown in table 1:

Table 1

Wherein, grid ID is the concrete numbering of grid; The terminal number of terminal number for occurring in the statistics 2G grid in the 2G grid; Support 2G﹠amp in the 2G grid; TD network terminal number is for supporting the number of the TD network terminal in the statistics 2G network environment grid; Support 2G﹠amp in the 2G grid; The terminal number of wlan network is for supporting the terminal number of wlan network in the grid in the statistics 2G network environment; 2G grid total flow is the total flow in the grid in the statistics 2G network environment; TD terminal refluence flow is the flow that flows backwards of TD terminal in the grid in the statistics 2G network environment in the 2G grid in the 2G network; Wlan network terminal return flow is the refluence flow of WLAN terminal in the 2G network in the grid in the 2G network environment in the 2G grid; The professional accounting of wlan network terminal P2P is to support the P2P service traffics accounting of wlan network terminal in the 2G network in the 2G network environment grid in the 2G grid; The professional accounting of TD terminal P2P is to support the P2P service traffics accounting of the TD network terminal in the 2G network in the 2G network environment grid in the 2G grid; Whether there is TD to be covered as in the 2G grid: for the grid that TD network road measurement data are arranged, can weigh with drive test data, not have the grid of TD network road measurement data, can collect coverage information by the CQT test; Whether there is the WLAN focus to judge whether there is focus in the grid for the focus longitude and latitude that provides according to operator in the 2G grid.

The TD drive test data is as shown in table 2:

Table 2

By above shunting, after implementing the collaborative work of three nets, following variation may occur user behavior: using before the shunting has the user of TD network capabilities terminal in the 2G network, and user's internet behavior can more occur in the TD network; Using before the shunting has the wlan network capable terminal the user of 2G network, and user's internet behavior can more occur in the wlan network; For the pure 2G terminal use of high flow capacity, after carrying out the specific aim marketing, its most of business should occur in TD or the wlan network.

Can weigh shunting effect by following index:

For each grid, can add up 2G net environment in the grid, the variation of pure 2G terminal flow accounting, TD terminal refluence flow accounting, WLAN terminal return flow accounting before and after the statistics shunting, if TD terminal and WLAN terminal flow accounting are high before the shunting, accounting reduces after the shunting, means that then this two Terminal Type branches to other network.More the large shunt effect is better to reduce ratio.

For the pilot zone, can (operator carries out the system of performance statistics to the network equipment by the wireless side network management data, the main equipment that must dispose in the network) variation of 2G network traffics, TD network traffics and wlan network daily average water discharge accounting (network management system of each system obtains respectively) in the pilot zone before and after the statistics shunting, if TD terminal and WLAN terminal flow accounting are high before the shunting, accounting reduces after the shunting, mean that then this two Terminal Type branches to other network, more the large shunt effect is better to reduce ratio.

The variation of the high hot number of cells of 2G in the pilot zone.Can produce by the interior WLAN terminal of situation of change, grid of the TD terminal refluence flow accounting in the grid situation of change of flow accounting.

Compared with prior art, there is following technological merit in present embodiment:

User profile is carried out ground physics and chemistry 50 * 50 grids location, and than the residential quarter, the fine degree of grid is higher, can better locate such as the accurate regional information such as residential building, commercial building, as dividing in the chamber, can accomplishing accurate location in the construction of WLAN; And most grid all has road in the city, utilizes grid can be well to carry out analysis-by-synthesis in conjunction with the drive test data of DT, and the situations such as the covering of every grid, interference, resource are positioned.

And present embodiment can support to carrier market department well that market department can analyze group units such as residential quarter, Party and government offices, industrial enterprise clearly from grid map.

At last, present embodiment can use rasterizing to instruct three net collaborative works well, can locate fast the refluence reason of focus grid, make the specialty ownership of shunting task clear, be convenient to each specialty and unit and carry out targetedly network operation, optimization, building-up work, impel the 2G data traffic to migrate to TD, wlan network.

Method of the present invention is not limited to the embodiment described in the embodiment, and those skilled in the art's technical scheme according to the present invention draws other execution mode, belongs to equally technological innovation scope of the present invention.
