Abstract

A network communication system with duplicate device detection in which a mobile communication unit, attempting to register to a communication network with a duplicate identification code as that of another mobile communication unit already registered, is detected and refused registration to the network. As a result, the mobile communication unit already registered to the network is not deregistered. Furthermore, the network communication system is not locked-up due to the existence within the system of two mobile communication units with the same identification code, thereby preserving data integrity within system and reducing potential downtime of the system due to lock-up.
