Blocking probabilities in GSM/(E)GPRS cells with different radio resources allocation strategies [articol]

Abstract

Resources allocation in GSM/(E)GPRS networks is very important because they are designed to transmit mixed traffic (voice and data) with varying characteristics. Based on a bi-dimensional model developed for voice and data traffic we make a study regarding the blocking situations that occur due to the lack of resources or voice priority. Complete partitioning (CP) and Partial partitioning (PP) schemes for cells allocation are considered. Original formulas for data blocking probability and voice preemption probability are established in both cases based on the Erlang-B law.
