INTELLIGENT PAGING STRATEGIES FOR THIRD GENERATION PERSONAL COMMUNICATION SERVICES NETWORKS
Partha Sarathi Bhattacharjee, Debashis Saha, Amitava Mukherjee · Journal of Interconnection Networks · 2000
We consider the problem of minimizing paging cost, subject to delay constraint, in Personal Communication Services Network (PSCN) and present two intelligent paging strategies for third generation systems. 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 proposed schemes lead to a decrease in paging signaling load at the cost of some extra processing power. When better discovery rate per cycle is expected irrespective of the incoming traffic PSIP is always preferred to other paging schemes primarily because of its less amount of polling delay. If the incoming traffic rate is low, SIP performs better than PSIP in terms of paging cost per cycle. However, the polling costs per cycle and the discovery rates for both the schemes become equal as number of paging requests per cycle increases. An improvement in respect of paging cost per cycle and discovery rate over conventional paging is shown with the help of simulation results.
