TitleImpacts of buffering voice calls in integrated voice and data services
AuthorsGemikonakli, E., Gemikonakli, O., Ever, E., Mapp, G. and Institute of Electrical and Electronics Engineers
Abstract

In this study, we aim to analyse the relationship
between various characteristics of a communication system
with data and voice call requests. Queuing theory and Markov
chain analysis are effectively used for this purpose. Such a
study is useful for understanding how the proposed
mathematical models behave which represents a system with
integrated voice and data calls in homogenous wireless
networks. We also propose to optimise the system
characteristics in an attempt to provide better Quality of
Service (QoS) for systems with integrated voice and data calls. The proposed models have two dimensions; one for voice calls and one for data calls. A channel is assigned for two input traffic call, namely, voice and data calls. The incoming voice and data calls are queued when the channel is busy. Since voice calls are delay-sensitive, priority is given to voice calls. Also,
since there is only one channel, data calls are only serviced if there are no voice calls in the system. For such systems, it is important to analyse the impact of buffering the voice calls as well as data calls for various mean rates of call requests, and mean service times. The analytical models presented are generic which is applicable for various systems with similar characteristics. Numerical results are also provided. The results show that the proposed models can be used for optimisation of the performance of a given network.
