In cellular systems, there is usually an overlap cell coverage area (area covered by two or more base stations) which has valuable practical applications: soft handoff is an important feature of CDMA systems, and in hard handoff, the overlap area allows the queuing of handover requests as a handover prioritization scheme. While an extensive research effort has been done to model the terminal residence time in a cell and the channel holding time, the sojourn time in the overlap area is a topic that still requires further study.
