Abstract: An approach to call access control based on soft handoff/double queue for multi-class traffic in 3G systems is proposed to give different priorities in accordance to different traffic. The different calls are controlled to enter into the networks according to different network conditions. And, especially, a soft-handoff/double queue model is used to ensure that the useful false soft-handoff requests not to be lost, so as to decrease the soft-handoff failure probabilities. Experimental results showed that the control model can allocate bandwidth dynamically and utilized network resource effectively and be realized easily on hardware to ensure effectively the QoS of different soft-handoff traffic. It has advantages of low soft-handoff call drop ratio and shorter time for waiting.
