On Efficient SC-Based Soft Handoff Scheme in Proxy Mobile IPv6 Networks

This study examines mobility support functions in soft handoff and IP-based mobile network, and distinguishes the control areas in the cell’s range areas. Several important characteristics of cell configurations for soft handoff are used to propose new structures for mobile network’s efficient session control (SC). A fixed-point strategy is proposed in order to not only determine the handoff traffic’s arrival speed, but stably calculate the loss probabilities or set the optimum guard channel numbers. We suggest a False Handoff Sessions (FHS) for improving the channel use efficiency based on mobility information. Numerical analyses indicate the efficiency of the presented Markov chain model and the advantage of proposed soft handoff method.
