Abstract After analyzing several abuses of transporting data service in existing WCDMA system, this paper presents a UL power control algorithm and relevant QoS guarantee. The new algorithm utilized some characteristic of data services, such as its controllable transport speed and low delay need. It is verified by emulator analysis that this algorithm can increase efficiently the utility factor of the system resource. At the same time, it also can improve the quality of communication when the system load is heavy and assure higher ratio of access when a new user try to access to system.
