Personal Communication Services Systems provides global roaming and improved quality of services irrespective of the location of its users. One of the important and challenging issues in personal communication services systems is location management, which keeps track of the movement of the users. The existing user location strategies used for location management suffers from high signaling traffic...
Mobility management, consisting of location management and handoff management, is a challenge for personal communication services (PCS) networks. Location management mainly involves two operations: location update and paging. A two-stage paging strategy with reinforcement learning is proposed. Under this scheme, each cell in a location area is given a preference. Besides, a small real number is used...
The location database (LDB) organization has much impact on the performance of personal communication services (PCS) network. In order to optimize the LDB organization, users' moving and calling patterns should be considered together. In this paper, we propose a hybrid strategy of location database clustering and dynamic hierarchical caching for a hierarchical database structure in PCS network. The...
One of the challenging tasks in a personal communication services (PCS) environment is to efficiently maintain the location of PCS subscribers who move from one region to another (hereafter called mobile users). When a mobile user receives a call, the network has to quickly determine its current location. The existing location management scheme suffers from high signaling traffic in locating the mobile...
