In this paper we have analyzed the number of handover required in different time stamp for a particular user on the quality of service parameters namely handover call blocking probability. This system model is based on the analysis of user mobility profile and assigns a weightage factor to each cell. The mathematical equation of the handover blocking probability derived from stochastic comparisons...
We consider scheduling and resource allocation for the downlink of a cellular OFDM system, with various practical considerations including integer tone allocations, different sub-channelization schemes, maximum SNR constraint per tone, and "self-noise" due to channel estimation errors and phase noise. During each time-slot a subset of users must be scheduled, and the available tones and...
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...
