Abstract

In International Mobile Telecommunication-2000 (IMT-2000) networks, the location management method to which has been used has a structural drawback: as the number of users increase, Home Location Register (HLR) should be used in the third generation Mobile Networks (MNs). In this paper we propose a new mobile management where the trace of mobile terminals is left in the Visitor Location Registers (VLRs), so that a call can be connected by querying only to the VLRs rather than to the HLR when the terminal-terminated- call occurs. The proposed method distributes messages to VLRs and effectively reduces mobility management cost. In the number results, the proposed scheme shows the improvement.
