METHOD FOR RECEIVING CALLS DURING FAILURE OF PROCESSORS IN VISITOR LOCATION REGISTER

摘要

PURPOSE: A method for receiving calls during failure of a processor in a visitor location register is provided to normally process a call destination of a mobile subscriber by making another processor register the location. CONSTITUTION: If a processor in charge of the location registration of a present mobile subscriber(100) maintains normal condition, the processor transmits a location registration request message of the mobile subscriber(100) to a home location register(400). In case that failure is generated in the processor, other processor maintaining normal condition detects the location registration request and the location registration request message to the home location register(S20).
