Call completion probability for a PCS network

In the emerging PCS networks, some calls may not be completed due to the handoff failure. It is very important to know the call completion probability for system design and performance evaluation. This probability depends on the distributions of the call holding times and the cell residence times. While the commonly used exponential distributions may provide good approximations for some cellular systems, they may not be appropriate for the emerging PCS network modeling due to the new integrated services. In this paper we derive formulae for the call completion probability under general call holding times and general cell residence times.
