Description
Technical field
The present invention relates to communication network wireless planning exploration field, survey addressing integrated by planning, accurately search equipment is simplified in planning, improve planning and exploration efficiency, when actual survey is carried out in theory planning site, Real-time Feedback survey information, thus realize the Site Selection of planning exploration efficiently.
Background technology
Current mobile 3G network is still in a high speed development stage, 4G network is at the early-stage, along with presenting, number of mobile users increases substantially, the continuous expansion of base station construction scale, how to ensure accurate planning, ensure the high efficiency of base station construction initial stage base station exploration Site Selection, effectively reduce the theoretical planning in base station and disconnect with actual conditions, greatly improve the ageing of planning exploration addressing.
Present stage is relatively independent for planning, exploration, the Site Selection of mobile communication network.Conventional station is planning network planning department extracts community (CELL) level counter count value by OSS (OSS:Operation Support System OSS), as TCH takies number of times (Traffic Channel Traffic Channel), TCH sweep time, access request number of times etc., calculate community TCH telephone traffic (TCH telephone traffic=TCH take number of times/TCH sweep time), the desktop GIS software of MapInfo company of the U.S. again with MAPINF(MapInfo) etc. ground physics and chemistry software community TCH telephone traffic carried out to ground physics and chemistry distribute, plan website by artificial selection again, not only workload is large, and website poor accuracy, the most theoretical planning website submits to construction department to survey addressing, the theoretical website that construction department provides according to network planning department carries out on-site land survey, and often theoretical website is not real site, selects 25 meters of left and right buildings as city, and theoretical site location does not satisfy the requirements, and can around deviation theory website, select, at this moment due to survey crew cannot Real-time Obtaining the existing network TCH telephone traffic distributed intelligence around of exploration website, thereby cause, to select alternative site be not best or unreasonable, as more than completing about half a year in cycle of planning, exploration, addressing of 200 website scales, in such time cycle, because the variation (as: impact of the factors such as dismounting on wireless environment of development, existing building) of wireless environment has reduced the ageing of planning and exploration, at present tradition exploration adopts manual mode: carrying notebook computer, mobile phone, laser range finder or tape measure, digital camera, GPS(global position system), the multiple exploration instrument such as compass, frequency spectrograph, data are mainly by manual mode record.Shortcoming is that collection data are disperseed, equipment carries heavy inconvenience, later data is processed loaded down with trivial details consuming time.
Summary of the invention
The present invention proposes a kind of accurate Site Selection method, first by rasterizing area to be planned, and the appraisal procedure proposing by the present invention selects continuous dilatation region U, increased the precision that telephone traffic ground physics and chemistry distributes, and improved the accuracy of base station planning.
Another the present invention has also solved planning and has disconnected with exploration addressing, simplifies the problem of search equipment, has realized the integrated problem of wireless network planning exploration addressing.
The method concrete steps of a kind of wireless base station Site Selection comprise:
(1) extract the traffic measurement file of area to be planned by data acquisition module by OSS system, from traffic measurement file, extract cellular traffic, cell carrier frequencies is counted information, data writing memory module; Artificial data configuration module is collected the information of existing base station in area to be planned, and imports data memory module; By base station planning analysis module, area to be planned is carried out to rasterizing, and by the cellular traffic in data memory module, cell carrier frequencies number and base station information are distributed in grid, the final grating map that has marked Hua Wu Liang ﹑ carrier frequency number and base station information that forms;
(2) by base station planning analysis module, the TCH telephone traffic situation of each grid step (1) Suo Shu is assessed, grid telephone traffic is greater than 4.8 be labeled as and need dilatation grid;
