QoS Guaranteed Call Admission Control Strategy for CDMA Networks

  • Received Date: 26 Dec 2005
  • Publish Date: 25 Dec 2006
  • To fully meet the requirements of multimedia for CAC(call admission control) mechanisms in CDMA(code division multiple access) systems,a method of calculating the residual capacity was investigated,and a QoS(quality of service) guaranteed dynamic CAC scheme was proposed.The analytical and simulated results show that the proposed CAC scheme may guarantee the QoS of different traffics,and improve the performances of call latency,outage probability and resource utility significantly.
