A comparative analysis of paging and location update strategies for PCS networks

Several alternative strategies for reducing paging and location update costs have been proposed in the literature. This paper compares four well-known strategies, that differ in the manner they approach the problem. The same mobility model and evaluation criteria was used for all strategies analyzed. Users are classified according to the call-to-mobility-ratio (CMR). Results are given weighting in different ways: the signaling cost in the radio interface and in the fixed network part.
