Abstract
The maximum bandwidth capacity of radio frequency channels such as the forward control channel (FOCC) used in the mobile switching systems is fixed. The FOCC has been experiencing severe congestion because of the inefficiency of conventional mobile paging methods. A bottleneck is caused in the FOCC due to constraints of both the bandwidth and the limited number of radio frequency channels in the mobile telecommunication systems. In this dissertation, an approach that minimizes the paging cost of FOCC in order to locate a mobile station in the mobile switching system is presented. In order to minimize the paging cost and to maximize the bandwidth utilization of the FOCC, a new paging schema with the optimal partition of paging zones is developed. By using the refined mobile's probability pattern stored in the statistical profile, the approach employs the genetic algorithm and the derived fitness function to generate the optimal partition of paging zones, such that the paging cost to locate a mobile station as well as the bandwidth consumption in FOCC is minimized.
