A Novel Strategy for Managing User’s Locations in PCS Networks Based on a Novel Hot Spots Topology

Abstract

As PCS networks aim to provide “anytime-anywhere” cellular services, they enable Mobile Terminals (MTs) to communicate regardless of their locations. However, in order to guarantee a successful service delivery, MTs’ real time location should be continuously managed by the network. Location management plays the central role in providing ubiquitous network communications services, which includes two fundamental processes, i.e., registration and paging. Registration is concerned with the reporting of the current locations of the MTs, while paging is used to locate the MT. Both processes incur signaling cost, and due to the scarcity of PCS wireless bandwidth and for more scalable mobile services, it is important to reduce that signaling cost. As The blanket paging in current PCS networks wastes a lot of wireless bandwidth, the author focuses on the subject of paging in attempt to reduce the paging signaling cost under delay bounds. This paper challenges the signaling cost problem and successfully establishes a family of probability based paging strategies. The author will introduce a novel topology for the network registration area, which is called the hot spot topology (HST) and based on HST, a novel location management strategy, which is called “Flower Based Strategy” (FBS) is also introduced.
