Abstract
Decomposition approximations in the past have been successfully applied to the performance analysis of preemptive priority based GSM/GPRS networks. In this paper, we propose a decomposition technique for the performance analysis of GSM/GPRS networks where GSM voice calls have non-preemptive priority over GPRS data packets. In other words, when demand exists for GSM circuit switched channels, the GPRS user can continue its transmission until the ending of packet transmission resulting in a delayed release of the channel. It is shown that such an approximation can be quite accurate in predicting both the impact of delayed release on GSM voice queuing as well as for comparison of immediate versus delayed release of channels on GPRS data queuing delays.
