An aggressive location restoration proposal bas on pointer

摘要

A proposal for smooth aggressive location restoration by forwarding pointer is given in this paper. A mobile communication system s robustness in case of a location-database failure is improved without the need for periodic location update operations. Radio resources would be saved at the cost of wire signal and operation of location databases. Meanwhile, a chain of forwarding location pointers has been used during the period of BLR failure. So mobile stations are unconscious of the failure of HLR, and mobile subscribers can always make outgoing call.
