Modeling of prioritized admission control supporting adaptive performance management in integrated voice/data CDMA systems

Abstract

Previous studies for CDMA admission control ignored traflic asymmetry analysis in both uplink and downlink. In this paper, we propose an admission control-based performance management framework for uplink and downlink connection in integrated voiceldata CDMA systems. Based upon reserved channels (guard channels), the prioritized admission control problem is formulated as a performance optimization model. The objective is to minimize handoff forced termination probability. For solving the-optimization problem, iteration-based Lagrangean relaxation approach is applied. This work provides both short-term and real-time admission control for updating system parameters and resource management, respectively.
