Analysis of measurement based prioritization schemes for handovers in cellular networks

A performance analysis of the first-in first-out (FIFO) and the priority queueing schemes, in comparison to the simple call handling scheme where there is no queuing, is presented. All analytical results are verified by simulation studies of the three schemes. With queuing of handovers, if all channels are occupied, new calls are blocked and handover requests are queued so that as soon as a channel is available, it is offered a handover request in the queue; new calls are blocked until the queue of handovers is emptied. In the priority queueing scheme, the mobile subscriber with the highest instantaneous priority is served first. The results indicate that the priority queueing scheme provides lower probability of forced termination and call blocking than FIFO queuing
