| We consider a probability criterion based location tracking scheme for personal communications systems. This scheme seeks to minimize the average signaling cost due to both paging and registration for individual mobile users. A timer-based location update and a single-step dynamic paging procedure are used. Each user-network interaction resets the timer(More)
We consider a new mobility management scheme – the Adaptive Location Area Tracking Scheme, in which each mobile performs a location registration as it crosses the boundary of its current personal location area and is assigned a new location area. The size and shape of the new location area depend on the mobile’s mobility and call characteristics in its(More)
We formulate the optimum personal paging area problem as an interval estimation problem, with an aim to reduce the paging signaling cost by minimizing the size of the paging area. A paging algorithm is developed to set-up the optimal one-step paging area that contains the locations of a mobile user with a high probability and thus to gain a coverage that is(More)
We consider the other-cell interference evaluation problem in a multi-cell CDMA system by looking at its location-dependence on the location distributions of mobile users in the cells. The goal is to characterize the location-dependent availability of radio resources in CDMA cellular networks. We model the locations of mobile users in a CDMA cell(More)
We consider an optimum personal paging area configuration problem to improve the paging efficiency in PCS/cellular mobile networks. The approach is to setup the boundaries of a one-step paging area that contain the locations of a mobile user with a high probability and to adjust the boundaries to gain a coverage that is matched to the mobile user’s(More)
