Abstract

We propose a new location management called Multicasting HLR with Forward Pointer (MHFP) which exploits receiver side call locality in Mobile Networks (MN). When a call is established, Multicasting HLR (MH) records the caller's VLR ID according to the callee. Periodically, MH ranks the VLRs and determines which VLRs frequently make calls to the callee. During a location registration process, MH sends the terminal's location information to the determined VLRs. And also, when a mobile terminal frequently moves between two Registration Areas (RAs) or within a small area, the terminal's location information does not register to HLR but to VLR using the Forwarding Pointer (FP) with unit length and link both sides.
