Abstract

Performance analysis of multi service UMTS networks is of major interest for mobile network providers. Because of the W-CDMA technique used in UMTS, which leads to an interference limited system with a dynamic cell capacity and load dependent cell coverage, the service mix has a big influence on the system performance. The paper provides a detailed description of the performance relevant mechanisms for the uplink of a single UMTS cell and extracts capacity bounds due to interference and power limitations for single and multi service operation. Based on these, a sophisticated Call admission Control algorithm is proposed. Finally, an analytical model is built for the system based on multi-class multiple queues system.
