Intelligent paging strategies for personal communication services network

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).Both are intelligent in the sense that cell(s) to be paged in a cycle are determined from the occupancy probability vector.Unlike the conventional blanket paging where all cells in a location area are polled at a time, in SIP (PSD?) one cell (a group of cells) is polled at a time.We compare the proposed methods with the conventional approach in respect of signaling load, polling cost, and delay.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.When better expected discovery rate per cycle is to be achieved, PSI? scheme should be chosen.The efficacy of these two intelligent paging strategies is shown with the help of simulation results.The following notations are used in this paper.
