An effective pointer-based HLR location registration scheme in location management for PCS networks

In this paper, a pointer based HLR (home location register) scheme for location management in PCS (personal communication service) network is presented. The proposed scheme maintained cache information at each HLR database. Whenever the mobile terminal (MT) moves from old service area to new service area, its entry will enter in to the cache that is maintained by the old service area. This entry tells about information of MT, i.e., to which SA (service area) it has gone. An analytical model is developed for studying the performance of the proposed scheme.
