Abstract

Wideband code division multiple access (WCDMA) systems are interference-limited. When a WCDMA system operates at nearly full capacity, admitting a new user may affect its stability. Therefore, proper call admission control (CAC) is crucial and should balance between quality of service (QoS) requirements for the new user as well as for the existing users and the required high capacity. In this paper, we investigate this tradeoff in the uplink direction using a power-based multi-cell admission control (MC-AC) algorithm. Multimedia services are considered with different QoS requirements in this algorithm. Different traffic distribution scenarios are also considered. Simulation results reveal that the MC-AC algorithm has many advantages over single cell admission control in terms of the overall stability of the system and the total system throughput.
