Mobile communication network and method for locking a selected remote mobile terminal device of the mobile communication network

摘要

A mobile telephone network in which user identify module (UIM) locking is activated automatically by the network via signalling over the base station to mobile telephone common air interface. The telephone network periodically or regularly queries the Internal Mobile Equipment Identity (IMEI) of the mobile telephone being used by subscribers on the system. If the IMEI of a mobile telephone is found on a 'stolen list' the network may then command the mobile station to activate UIM locking by messaging to and from the mobile telephone over the air interface to activate the UIM locking function using a transmitted bit pattern.
