Analysis of Adaptive Multi-Rate System for Elastic Traffic

Cover Page

Abstract


Wide expansion of 3G networks in many countries and since the end of 2007 year in Russia as well sets new teletraffic problems. A lot of interactive services and high speed internet access produce great volume of elastic (data) traffic that composes significant part of total traffic in modern wireless networks. The use of classical Erlang multiservice model for 3G networks modelling is restricted due to the system assumes only constant bandwidth utilization by calls. In this work we propose adaptive multirate system in the form of multiserivce queueing system with elastic calls, which removes above restriction from Erlang multiservice system. An effective approximate algorithm for calculation of steady-state distribution and formulas for main QoS parameters are given. Obtained results can be applied by cellular 3G operators in their activities.
