使用Cellular Towers C＃Windows Mobile获取多个Cell ID以进行定位

根据Microsoft关于RIL的文档，我已经能够实现检索Cell ID，LAC，MCC，MNC和Signal Strength的代码。 使用这些数据和http://www.opencellid.org/我能够检索到该细胞塔的纬度和经度。 问题是我需要实现某种三角测量算法以获得更准确的位置。 但在考虑三角测量之前，我需要使用多个塔ID。 我怎么能得到它们？ 我试图创建一个towerIDs数组并在循环中填充它，而数组中不存在塔ID然后添加它，但如果它存在则忽略它并继续寻找另一个。 显然它没有用，一旦它得到它保持它，如果我删除对象并创建一个新的它得到相同的塔。 我怎么能得到一个不同的？

提前致谢。

尝试保存有关当前信号的所有信息，在这样做之后重新启动服务寻找另一个信号，但首先检查你存储的信号，如果它是相同的忽视并继续寻找。 祝好运！
