An adaptive admission control strategy for multi-services in WCDMA system

The third generation mobile communication systems are expected to offer a large variety of services and calls for more flexible and efficient admission control strategy. This paper presents an adaptive admission control strategy for uplink transmission in WCDMA systems. The adaptive strategy gives priority to handoff calls and dynamically adjusts the number of guard channels according to the failure rates of the handoff calls. Simulation results demonstrate that the proposed strategy is more robust than fixed strategy under different mobility enviroment.
