如何从CellSignalStrengthLte获取5GNSA网络的信号强度特征
如何从CellSignalStrengthLte获取5GNSA网络的信号强度特征
提问于 2021-08-12 21:37:20
正如安卓开发人员所说，TelephonyManager只为5G SA网络返回CellInfoNr，为5G NSA网络返回CellInfoLte。我需要获取美国国家安全局网络的信号强度信息，但找不到如何从CellSignalStrengthLte获取的信息。
据我所知，5G使用同步信号和信道状态信息，而不是像4G那样使用小区特定的参考信号，因此通常的RSRP、RSRQ和RSSI信息对于5G网络非常无用。
我是不是理解错了，以至于这些指标实际上在美国国家安全局网络中是相关的，或者我如何从CellSignalStrengthLte对象中获得相关的指标？

也许能帮你打给TelephoneManager你可以在下面看到所有的类型。
使用如下所示的函数：
fun getNetworkInfo() : Int {
val networkInfo = connectivityManager.activeNetworkInfo
if (networkInfo.type == ConnectivityManager.TYPE_MOBILE) {
return networkInfo.subtype
} else -1
}然后解析Int以检查连接的类型。
连接类型：

* Do not add negative types.
