A Sector-Based Location Management Scheme for PCS Networks

This paper focuses on the problem of location update and terminal paging. In order to save the limited wireless channel resource, mobile terminals should not update their location information whenever they crossing the boundaries of adjacent cells. Similarly, network should not page every cell one by one when an incoming call arrives. In this paper, a sector-based location management scheme (SLMS) is proposed. In SLMS, we use sector-based location update scheme and sector-paging scheme. An analytical model is developed to calculate the cost and we compare the cost of SLMS with that of existing scheme. The numerical results show that our SLMS has a good performance when the number of incoming calls is high.
