Static registration grouping scheme to reduce HLR traffic cost in mobile networks

Abstract

This paper proposes the static registration grouping scheme that solves the Home Location Register (HLR) bottleneck due to the terminal's frequent registration area (RA) crossings and that distributes the registration traffic to each of the local signaling transfer point (LSTP) area. The RAs in LSTP area are grouped statically. It is to remove the signaling overhead and to mitigate the Regional STP (RSTP) bottleneck. The proposed scheme solves the HLR bottle-neck due to the terminal's frequent RA crossings to each of the LSTP area. © Springer-Verlag Berlin Heidelberg 2005.
