Reduction of Location Update Traffic Using Virtual Layer in PCS

In mobile wireless network efficient location management for tracking and finding mobile users is a critical issue. The traffic for location update can be excessive, especially at the base stations that are near to the location ea (LA) boundaries. In s paper we propose a new location ate scheme which can significantly reduce the signaling traffic for location ate. It is based on the virtual layer approach employing SubMSCs. The virtual layer is d upon the original layer of LAs such that the mobile terminals moving around the boundary cells of acent LAs become to move within a virtual LA. As a result, the location ate traffic is substantially reduced compared to overlapping scheme which is the most recent and efficient location ate scheme.
