Future mobile telecommunication systems have to offer advanced multimedia services to a large number of users. The burden imposed by the signaling operations supporting these services can severely degrade the system performance and lead to congestion problems in network equipment (switches, databases, gateways, etc.). Paging operations in a mobile cellular network are responsible for a large part of the signaling load and, therefore, the issue of how to conduct them efficiently becomes of critical importance. The key to its solution lies on the application of multiple-step paging schemes and on the "proper" planning of paging areas. We devise and solve a version of the paging area planning problem. In particular, we provide a low complexity algorithm capable of reducing the paging cost, at the price of a moderate increase in the call set-up delay.
