Improved channel allocation for voice and data traffic with resource reservation for voice traffic in EDGE system

Abstract

This paper makes two main contributions. The first is a method that combines TDMA time slots for voice and data packet services to offer high peak rates and guarantee packet connectivity in the case of cell congestion. The method can also be used to analyse time slot reservation for voice or data packet services. The second contribution is a novel method for analysing the system. In addition to the traditional approach that consists in solving a large system of equations to compute state probabilities, a combinatorial method that simplifies the analysis and that can be applied to larger and more complex systems is introduced. © 2008 Academy Publisher.
