Analytical Model of the WCDMA Radio Interface in UMTS Network with User Differentiation

Abstract

The paper presents an approximate method for modeling of the WCDMA interface in the UMTS network in which the mobile operator introduces priorities and user differentiation. In our considerations we use a model of the full-availability group servicing multi-rate traffic with priorities for services. In the proposed model we assume that user priorities and the priorities for classes of services are introduced into the network. The proposed scheme is applicable for cost-effective WCDMA resource management in 3G mobile networks and can be easily applied to network capacity calculations.
