On the Handoff-Call Blocking Probability Calculation in W-CDMA Cellular Networks
In this paper, we investigate the call blocking probability calculations in the uplink of W-CDMA mobile cellular networks. In these networks, we distinguish two types of blocking, the new-call blocking, which concerns the initial call establishment request, and the handoff-call blocking, due to the users’ mobility from one cell to the other. To analyze the system, we describe it by a Discrete Time Markov Chain, and based on it, we derive a recursive formula for the calculation of the state probabilities. Consequently, the new-call blocking probabilities and the handoff-call blocking probabilities are determined. To evaluate the proposed formulas, the analytical results are compared with simulation results. This comparison shows that the accuracy of the proposed formulas is very satisfactory.
