> Interestingly, GSM does allow for priority of emergency calls (112, 999, etc). IIRC, the SIM can make a priority request to be connected to the emergency services. The network could disconnect a non-emergency call to free up the air interface. An emergency call on GSM doesn't really "call" a number in the traditional sense-- the number is never even transmitted. This is also why emergency services can be reached by the GSM standard number (112) or other emergency numbers specified by the phone or the SIM itself. |
