我一直试图获得celllid，lac，mcc和mnc。虽然可以找到mcc和mnc，但是cell-id和lac仍然是null。这是代码（并且已知根据正在进行的线程数工作但我仍然无法使其工作）

我已经从here获取代码（我希望它现在可以在nokia e50上运行，因此使用了com.nokia.mid.cellid（事实上我已尝试过此链接中提到的所有其他选项）））Cellid和lac都返回null，同时正确返回mcc和mnc。

Answer 1

我确认无法从E50收到小区ID。但我已经编写了多种平台解决方案，我将在各种设备（我们的生产环境中使用> 1000台设备）上进行检查。我从相同的链接获得原型，但说实话 - 编写它的人并没有给出细节。

我非常怀疑我的代码会在至少一半的设备上运行，但我们很快就会看到它。

Answer 2

您在网站上提及的内容是否已阅读此行

但是获得Cellid仍然受到手机平台，签名证书和运营商的限制：

诺基亚   s40第3版Fp1版，要求运营商或制造商签字   S60第3版，FP2（2008年发布，更新版，不适用于N95），不需要唱歌。

Answer 3

我刚刚在工作中得到了一个诺基亚设备S60惠普Symbian第5版，我正在尝试根据手机ID获取手机位置，而不是gps。所以，为此，我使用http://www.opencellid.org/，这个页面检索我的位置，但它不完全像gps'。但是，为了做到这一点，我需要mnc，mcc，cellid和lac，令我惊讶的是，这个设备并没有给我lac，mnc和mcc，这样的lalchetian说。我们这里有一个严重的问题。可能这些属性仅在某些设备中可用。

无法在诺基亚S60上检索CELL-id和LAC（在E50中尝试过）
