Influence of the handoff process on the channel holding time distribution for cellular systems
D. Lara-Rodríguez · 2002
Traffic capacity improvement is a strong necessity of cellular systems. One of the main techniques to increase capacity is the utilization of microcells. However, as cells are reduced, handoff rates are increased. In this paper the influence of the handoff process in the channel holding time is studied. The channel holding time is defined as the time duration between the instant that a channel is occupied by a call and the time it is released by either the completion of the call or a handoff. It is shown by simulation that the channel holding time distribution can be fitted by an exponential distribution for signal strength based handoff algorithms.
