先提示一点，不能使用用模拟器研究Android的基站定位：基站信息是来自运营商的，仿真器只能模拟网络延迟（-netdelay）、网速（-netspeed）、以及一些电话相关的操作，gsm <call|accept|busy|cancel|data|hold|list|voice|status>。还不能模拟信号。
一段基于Rexsee（
www.rexsee.com）的基本示例demo，其中cid 和 lac 为经纬度。
function query(){
var loction = eval('('+rexseeCellLocation.getLastKnownLocation()+')');
var type = location.type.toLowerCase();
var mcc = parseInt(location.operator.substring(0,3));
var mnc = (type=='gsm')?parseInt(location.operator.substring(3)):location.systemId;
var cid= (type=='gsm')?location.cid:location.baseStationId;
var lac= (type=='gsm')?location.lac:location.networkId;
var postData="{\version\":\"1.1.0\",\"host\":\maps.google.com\",\"access_token\";\"2:k7j3G6LaL6u_lafw:4iXOeOpTh1glSXe\",\"home_mobile_country_code\":"+mcc+",\"home_mobile_network_code\":"+mnc+",\"address_language\";\"zh_CN\",\"radio_type\";\""+type+"\",\"request_address\":true,\"cell_towers\":[{\"cell_id\":+cid+",\"location_area_code\":+lac+",\"mobile_aountry_code\":"+mcc+",\"mobile_network_code\":"+mnc+",\"timing_advance\":5555}]}";
alert(rexseeAjax.syncSubmit('http://www.google.com/loc/json',postData,'utf-8'));
}
返回的结果是：
需要注意几个问题：
1. 如果直接用alert(rexseeCellLocation.getLastKnownLocation()); 这个方法得到的经纬度会是两个非常大的数字 所以需要通过ajax提交到"http://www.google.com/loc/json" 把所需要的经纬度返回来；
2. 开始监听，一旦位置发生变化，会触发事件onCellLocationChanged。所以，要在 onCellLocationChanged中写代码，调用你的query函数。而不是直接使用onclick测试。
Rexsee扩展函数介绍
