ABSTRACT:
A multi-channel cellular communications intercept system for monitoring and then intercepting communications between a mobile unit and a base station in one cell of a cellular telephone system. The system includes a controller and a plurality of receivers with each receiver monitoring the forward control channel from a different cell within a geographical area of interest. When a global page for a target mobile unit is received, one of the receivers in the system is retuned to the forward voice communication channel on which the target mobile unit will be broadcasting for the purpose of monitoring and/or recording the conversation. The remaining receivers are retuned to the strongest forward control channels in the area.
