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.

Movement prediction oriented adaptive location management provides a major role in personal communication service (PCS) system. Generally the GSM system supports two level architecture. Because it supports two kinds of databases-Home Location register and Visitor Location Register. Every time when the user crosses the location area it has to register with the HLR. This creates high cost for registration and location tracking as it involves the use of costly bandwidth between the Mobile Switching Center (MSC) and the HLR. In this paper the technique for reducing the costs during the location tracking and location update is proposed. Taking the movement prediction of the users it creates the block and the user registers with the HLR only after crossing the block instead of crossing the single cell. This movement prediction is generated using one neural network model for all the users. The block register (BR) is introduced between the block and the HLR in two level systems, thus introduces three level architecture. In this architecture some signaling cost values between the MSC-BR, BR-HLR and BR-BR are maintained to get the better performance. In this proposed system the aim is to set the value between the MSC and BR and the two BR as small as possible and the value between the BR and the HLR must be higher to get the better performance.
