Abstract

In this paper, we propose and analyze a different channel allocation scheme in mobile cellular networks which not only gives priority to handoff calls but also tries to protect originating calls. We use channel reservation to protect handoff calls and in contrast, to protect originating calls, we set a maximum reservable channel, NG, in our scheme. In channel reservation schemes, there are some periods that reserved channels are not actively utilized. In this paper, these periods are defined as dead time. Some new performance measures of the system such as the distribution and the mean dead time of a reserved channel are obtained. The main contribution of this work is to find optimum NG so as to maximize the service provider's revenue while customers' satisfaction (in term of connection continuity) and system utilization (in term of system capacity and less dead time) are justified jointly. We assume a general cost structure which is due to blocking of handoff calls, blocking of originating calls and unutilized periods of reserved channels. Based on the total cost, we investigate the trade-off between the service utilization and customers' satisfaction.
