Abstract : This paper presents two intelligent paging strategies for a Personal Communication Services Network (PCSN). They are termed as sequential intelligent paging (SIP) and parallel-o-sequential intelligent paging (PSIP). Unlike the conventional blanket paging where all cells in a location area are polled at a time, in SIP (PSIP) one cell (a group of cells) is polled at a time. The cells to be polled are determined from the occupancy probability vector. The objective is to reduce the signaling load. The proposed schemes lead to a decrease in paging signaling load at the cost of some extra processing power. When high intensity traffic is expected, PSIP is always preferred to other paging schemes. However, when incoming traffic rate is low, SIP performs better when paging cost per cycle is the criterion for choosing a particular scheme of paging. The efficacy of these two intelligent paging strategies is shown with the help of simulation results.
