PAGING SYSTEM IN MOBILE COMMUNICATION AND METHOD THEREOF

摘要

PURPOSE: A paging system in mobile communication is provided to install a registration list where identifiers are registered, and to update the registration list whenever receiving calls are generated in mobile terminals or the mobile terminals move between cells, thereby saving paging frequency and paging channels. CONSTITUTION: An HLR(310) and VLRs(321,322) search an area where a receiving mobile terminal(200) is located, according to a call request of a transmitting terminal station(100), and transmit a call. MSCs(331,332) receive the call from the HLR(310) and the VLRs(321,322), and transmit paging request signals. Base stations(351-356) receive the paging request signals from the MSCs(331,332), and determine whether to page by retrieving a registration list, then determine to maintain or delete information of the corresponding receiving mobile terminal(200).
