QoS analysis in mobile cellular networks supporting voice and class of finite sessions

摘要

This paper presents a queuing analysis for mixed voice and data in mobile cellular radio networks that is germane to GSM/GPRS. The work considers a class that consists of a finite number of open sessions and illustrates the quality of service (QoS) on such systems. We start with a general model description in which an analytical model provides the mean delay and the number of data users that are continuously backlogged. A computational algorithm of this is then formulated which significantly improves facility. Both of these works are novel and topical. For this work, complete sharing scheduling for both real and non real-time services is considered. The real-time service is modelled as circuit switched and non real-time service as packet switched. The results are corroborated using the simulation package OPNET. QoS in terms of mean delay and the access policy for a new data user joining the network is also discussed.
