ABSTRACT
The maximum bandwidth capacity of the radio frequency channel such as the forward control channel (FOCC) is limited in a mobile switching system. The FOCC has been experiencing severe congestion because the inefficient conventional mobile paging methods cause the bottleneck in the FOCC due to constraints of both the bandwidth and the limited number of radio frequency channels in mobile telecommunication systems. In order to minimize the paging cost and to maximize utilization of the bandwidth in the FOCC, we develop a new paging schema with the optimal partition of paging zones. By using the refined mobile’s probability patterns stored in the statistical profile, we employ 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 the FOCC is minimized.
