Call admission control in multiple service DS-CDMA cellular networks

Abstract

In this paper we develop traffic models for single and multiple cell CDMA networks with multiple classes of mobile subscriber. The key feature of this development is the specification of an effective bandwidth based call admission control procedure that details the numbers of mobiles of each class in each cell that the system operator should allow in order to maintain an acceptable quality of service. The CDMA mobile network, operating within the admissible region described above, has a very similar form to a circuit-switched network operating with fixed routing. This similarity allows the existing traffic modelling techniques and network management strategies for general loss networks, to b..
