CUI Hong-yan,XU Hai-bo,TIAN Hui,ZHANG Ping(WTI Institute,Beijing University of Posts and Telecommunications,Beijing 100876,China)  
A new access control algorithm-PCD algorithm is introduced in this paper.It adopts an uplink access control scheme that can effectively guarantee the user's QoS based on the characteristics of all kinds of service traffic in WCDMA system.It allocates network resources according to the classification and QoS of the traffic.The signaling procedure of the real-time service and non-real-time service are designed,and the simulation evaluation for the new algorithm and the existing access algorithm are done finally.
