Abstract
There are many studies dealing with handover statistics for voice wireless calls, however handovers of multimedia traffic is still in its early stage of investigation. A major difference is that neither the Call Holding Times (CHT) nor the Cell Residence Times (CRT) can be longer assumed as exponentially distributed. In this paper, we obtain analytical expressions for a variety of handoff rates for Erlang-based call holding times and cell residence times. In particular, we present closed-form analytical results for the handoff cell arrival rate in the following cases: (1) mixtures of exponential distributions for the CHT and any distribution for the CRT, (2) mixtures of k-Erlang distributions for the CHT and exponential CRT, and (3) 2- Erlang distributions for CHT and CRT. We match parameters with the birth-and-death stochastic process model and we give some insights for simulations.
