Mobile and wireless network technologies enables us to communicate each other at any
time, any place in the ubiquitous personal communications services(PCS). Among the
technologies, location management of mobile users is one of the most important problems for
tracking the location of mobile users. The location management basically is performed by
using two registers, HLR(Home Location Register) and VLR(Visitor Location Register).
Location of the mobile user is registered to the two databases for call tracking. And those
registration operations cause many network traffic. In this paper, we propose a new simple
location management by registering representative VLR of group of several VLRs regionally
and broadcasting for searching a mobile user, so called rVLR-B. We manage the
representative VLR of several VLRs and register mobile users’ location. When set up the call
path between mobile users, the VLR of the caller queries callee’s rVLR for searching the
location of callee instead of requesting to VLR of callee. And then rVLR broadcast the
callee’s location to all VLR of the region concurrently. Location registration is only
performed when a mobile user visits a new rVLR network area from current area. Using the
rVLR-B, we can reduce the cost of maintaining location of mobile users.
