We present an improved paging algorithm for user in his resident LA in PCS networks:resident cell paging strategy.By analyzing the cell residence times of users
the system first pages user's resident cell and then other cells if the first page fails.Compared with current systems
the method can reduce paging cost greatly and further raise wireless resource usage efficiency.The potential disadvantage of the paper is that the paging delay of the first incoming call to some users in their non-resident cells may be twice the delay in current cellular systems.
