Abstract

An important parameter in the analysis of a communication system is the channel holding time of a call. In a mobile communication system, the cell channel holding time may be different than the call duration due to the mobility of the user. To study this impact of the user mobility, a new and general mobility model is presented and analyzed. This model is valid for a wide variety of different types of user mobility and is used to derive the Laplace transform of the probability density function for the channel holding time. The channel holding time is expressed in terms of the mobility model parameters and the call duration. From this result, the average and coefficient of variation of the channel holding time are presented and discussed. A comparison between this model and one which assumes constant user speed is also presented.
