Abstract
The invention overcomes the inefficient conventional mobile paging methods that cause a bottleneck in the FOCC due to constraints of both the bandwidth and the limited number of radio frequency channels in mobile telecommunication systems. This is accomplished by first determining the mobility pattern of each mobile station during a given sampling period. Then the probability that the mobile station will be located within each cell in the network is determined. From the cells having non-zero probabilities, at least two paging zones are defined using a genetic optimization method which converges on paging zones which produce a minimum paging cost which correspondingly results in minimum utilization of the FOCC.
