摘要
In this paper, a simulation model with priority scheme for service of the process of changing the channel associated with the current connection while a call is in progress at cellular radio networks is proposed. At this model the heterogeneous traffic is served on the base of different handover queues for voice calls and data transfer. An handover scheme with three priority levels is presented. A simulation algorithm and a PHP program for estimating probabilistic parameters of quality of service (QoS) are worked out. The purpose of simulation is to estimate the probabilistic parameters of Quality of Service such as blocking probability of dropped voice calls, cell loss, data transfer delay etc. and to determine constraints, which have to be fulfilled for improving of QoS parameters. Simulation results are shown.
