Abstract
A monitoring computer monitors the communications occurring within at least one communication system for at least one unique communication unit identification code (unit ID code) associated with a communication unit. Upon detecting the at least one unit ID code, the monitoring computer compares the type of communication made by the communication unit with known software parameters (including the allowable types of communications) for the communication unit. When the type of communication made by the communication unit does not substantially match the known software parameters for the communication unit, the communication unit is identified as using an unauthorized and/or duplicated software application.
