相邻小区的 UMTS 小区 ID
问题是，当我使用下面的源代码时，我仅在 2G 模式下收到小区 ID，如果我切换到 3G 模式，我有时会收到 HSDPA 的 -1 或 UMTS 的任何信息。源代码是：
for (int i = 0; i < neighCell.size(); i++) {
try {
NeighboringCellInfo thisCell = neighCell.get(i);
int thisNeighCID = thisCell.getCid();
int thisNeighRSSI = -113 + 2*thisCell.getRssi();
log("Base station "+(i+1)+":"+
"\nCellID: "+thisNeighCID+
"; RSSI: "+thisNeighRSSI+" dBm");
} catch (NumberFormatException e) {
e.printStackTrace();
NeighboringCellInfo thisCell = neighCell.get(i);
log(thisCell.toString());
}
}
有没有办法在 3G 模式下获取 id，尤其是 UMTS？
The problem is that when I use source code below, i receive cell id's only in 2G mode, if i switch to 3G mode i sometimes receive -1 for HSDPA or nothing for UMTS. Source code is:
for (int i = 0; i < neighCell.size(); i++) {
try {
NeighboringCellInfo thisCell = neighCell.get(i);
int thisNeighCID = thisCell.getCid();
int thisNeighRSSI = -113 + 2*thisCell.getRssi();
log("Base station "+(i+1)+":"+
"\nCellID: "+thisNeighCID+
"; RSSI: "+thisNeighRSSI+" dBm");
} catch (NumberFormatException e) {
e.printStackTrace();
NeighboringCellInfo thisCell = neighCell.get(i);
log(thisCell.toString());
}
}
Is there any way to get id's in 3G mode and especially for UMTS?

您获得的 -1 值对应于 UNKNOWN_CID 常量的值，这表示单元格位置不可用。
您可以在此处的 API 中确认这一点。
它还指出与您要获取的信息相关的 get 方法仅适用于 GSM。对于 UMTS 和 CDMA，它将它们视为未知位置。
The -1 value you are getting corresponds to the value of the UNKNOWN_CID constant, which indicates the cell location is not available.
You can confirm this in the API here.
It also states that the get methods related with the information you want to acquire, only work in GSM. For UMTS and CDMA it treats them the same as unknown location.
