ABSTRACT:
A method for detecting fraud in a cellular radio telephone system. Fraud is suspected when the system detects a multiple access from a mobile station, when an activity collision occurs, when the system receives a premature registration from the mobile station, when auditing or operator-initiated locating of the mobile station reveals the existence of the mobile station in two locations simultaneously, or when tracing of mobile subscriber activity reveals unusual activity.
