In this paper we present a soft handover algorithm for wide band CDMA has been developed and implemented in the framework of a system level UMTS simulator, this algorithm depend on measurement of Average Received Signal and speed of user, the evaluated under the uplink and downlink UMTS system, the performance of the proposed algorithm is evaluated under different speed scenarios for User Equipment(UE) It shown via OPNET simulation, the proposed handover algorithm can effectively reduce the delay compared with Integrator Handover Algorithms, provided solution to improvement the performance in UMTS network by minimizing delay(Queuing sent delay, Uplink tunnel delay, Down link tunnel delay) and Packet loss ratio and BER and busy. Moreover, the total system throughput higher, the comparative analysis for all metrics carried out and gave the best performance for the proposed algorithm.
