寻找获取附近 GSM 小区的 LAC/CID 的方法
我知道使用以下 AT 命令很容易获取当前注册的 GSM 小区 LAC/CID 信息：
AT+CREG=2 OK AT+CREG? +CREG: 2,1,"0C71","2078"
但我不知道如何获取附近小区的 LAC/CID。我有一个名为 RF Signal Tracker 的 Android APK，它显示以下信息：
Reselection Nbrs: 5 n0: -85dBm, CI0: 62002 n1: -93dBm, CI0: 62193 n2: -95dBm, CI0: 61537 n3: -97dBm, CI0: 61532 n4: -97dBm, CI0: 61971
哪些是附近小区的 CID。
有谁知道如何通过AT命令获取这些？
谢谢。
I know it is easy to get the current registered GSM cell LAC/CID information with following AT commands:
AT+CREG=2 OK AT+CREG? +CREG: 2,1,"0C71","2078"
But I don't know how to get nearby cells' LAC/CID. I have a Android APK called RF Signal Tracker, which displays following information:
Reselection Nbrs: 5 n0: -85dBm, CI0: 62002 n1: -93dBm, CI0: 62193 n2: -95dBm, CI0: 61537 n3: -97dBm, CI0: 61532 n4: -97dBm, CI0: 61971
which are CIDs for nearby cells.
Does anyone know how to get these via AT commands?
Thanks.

根据 GSM 规范，提供此信息不是强制性的。尽管如此，一些制造商还是提供了它。但由于它不属于标准，因此命令和输出格式不标准。
有些调制解调器只提供连接站点的 MCC、MNC、LAC、CELL_ID、SIGNAL_STRENGTH。
其他一些也提供有关相邻小区的信息。
例如，Cinterion 有 AT^SMOND - 专有命令。它提供有关连接的以及相邻小区的信息。
Providing this information is not mandatory as per the GSM spec. Still, some manufacturers provide it. But since it is not covered by standards, the command and the output format is not standard.
Some modems just give MCC,MNC,LAC,CELL_ID,SIGNAL_STRENGTH of connected site.
Some others give information about neighbouring cells as well.
For example, Cinterion has AT^SMOND - a proprietary command. It gives information about connected as well as neighboring cells .
AT#MONI 命令并非所有 GSM 设备都支持。
以下是一些示例：http://www.roundsolutions.com/forum/thread。 php?threadid=2078
There is command AT#MONI which is not supported by all GSM devices.
