The distance-based location area update mechanism of CDMA 1X EV-DO achieves circular location areas around the cell in which the mobile makes the update. In this paper, we enhance this technique by achieving arbitrary location area shapes tailored to the known mobility patterns of mobiles. We develop a heuristic iterative algorithm that searches for the optimal shape which maximizes the time between...
We design an efficient radio admission control algorithm that minimizes blocking probability subject to the condition that the overload probability is smaller than a pre-specified threshold. Our algorithm is quite general and can be applied to both TDMA-based cellular technologies, such as GPRS and EDGE, and CDMA-based technologies, such as UMTS and CDMA2000. We extend prior work in measurement-based...
