Abstract
Call Admission control (CAC) is an important part of radio resource management (RRM) according to certain criteria, CAC determines whether the call is admitted to access or not. CAC is an important means to guarantee the quality of service (QoS) in wireless network. This paper analyses the multi-user detection factor on the uplink load of TD-SCDMA system and the effects of adjacent cell interference theoretically. A CAC algorithm based on the soft-block (SB) is proposed after discussing the shortage of traditional CAC algorithms in TD-SCDMA system in the paper. The simulation results show that the proposed algorithm has a lower blocking rate and call drop rates, and provides a better QoS to access users. At the same time, it has also higher resource utilization.
