In this paper we are considering a mixed platform wireless environment. It means that the mobile spent a Cell Residence Time (CRT) in the originating cell which is a random variable with different statistics from the CRT's in the remaining cells. We model this situation by using a delayed renewal process and we present closed-form mathematical expressions for the probability mass function of the number of handovers during the random interval of a Call Holding Time (CHT). We have modeled the CHT as a mixture of exponential distributions and any distribution for the CRT's, and we establish an interesting relationship between them. In particular, we have considered generalized gamma and circularly distributed CRT's. We also present results for the probability of no completing a call and estimates for the handover rates.
