ABSTRACT:
Apparatus and methods for the lawful intercept of mobile telecommunication are provided. The A Interface at a base station subsystem is bridged with a Y-cable, and a copy of the data on the telecommunications lines are forwarded to a switch. The out-of-band control information such as SS7 signalling information is forwarded to a processor which continuously monitors the mobile identification numbers and/or telephone numbers of called and calling parties and compares the numbers to a database of to-be-tapped numbers. Upon finding a match, the processor causes the switch to provide the copy of the channel on which the call is being carried to a listening device.
