通过Web页面获取基站位置Web端源码



首先要清楚一点的是，每一个基站都能够通过请求http://www.google.com/loc/json获取到一个经纬度。如果用户能够在短时间内获取到较多的基站信息，比如4个或5个，可以通过这几个基站的经纬度计算出比较准确的用户位置。



举个例子，比如我在WM上取到4个基站信息：

50554,9513,460,1



50325,9513,460,1



50584,9513,460,1





50041,9513,460,1



每一行的4个数值分别对应：CID, LAC, MCC, MNC



CID——CellID，表示基站号



LAC——Location Area Code，表示区域编号



MCC——Mobile Country Code，表示国家编号，中国是460



MNC——Mobile Network Code，表示移动网络编号，移动是0，联通是1



然后向Google发送基站信息是通过JSON串以Post的形式发送到http://www.google.com/loc/json，然后它会返回一个包含经纬度信息的JSON串-Web page for the base station location by Web-side source



First of all must be aware that each base station can request http://www.google.com/loc/json get through to a latitude and longitude. If the user can quickly access to the base station more information, such as 4 or 5, these base stations can be calculated more accurate latitude and longitude of the user location.



For example, such as WM, I get to 4 on the base station information:

50554,9513,460,1



50325,9513,460,1



50584,9513,460,1





50041,9513,460,1



Each line of the four values correspond to: CID, LAC, MCC, MNC



CID- CellID, said base station No.



LAC- Location Area Code, said regional code



MCC- Mobile Country Code, said the national numbers, China is 460



MNC- Mobile Network Code, said the mobile network number, mobile is 0, Unicom is a



Base station then sends the information to the Google JSON string through the form to send to the Post http://www.google.com/loc/json, then it will re
