To support call locality (CL) in wireless networks, we locate the cache in local signaling transfer point (LSTP)lev el. The terminal registration area (RA)crossin gs within the LSTP area do not generate the home location register (HLR)t raffic. The RAs in LSTP area are grouped statically. It is to remove the signaling overhead and to mitigate the RSTP bottleneck in dynamic grouping. The idea behind LSTP level caching is to decrease the inconsistency ratio (ICR) with static RA grouping. Our scheme solves the HLR bottleneck problem due to the terminal' frequent RA crossings.
