In wireless communication network especially when mobile station carried out its mobility and maintained the stabilization of connection while there is automatically changes in services between base station for mobile station, handover method is needed to guarantee the comfortable of communication without having obstacle in the distance of base station and the speed of mobile station. The comfortable of communication during handover is depend on the quality of service that provide the difference level of service in arranging and giving the traffic priority in the network in mobile station for voice over IP (VoIP) application that using internet network. This research used wimax network to know the influence of handover towards the performance parameter quality of service for voice over internet protocol services when entering the critical area with the constant speed. Simulated used optimized network engineering tools (OPNET) 14.5 modeler educational. Based on the testing that was carried out for hard handover and soft handover method used voice over internet protocol application,has obtained value jitter is better for the speed 65 km/hour than for the speed 20 km/hour. In the speed 85 km/hour using soft handover for 3 users the value delay is 26.6 millisecond, and it is influence to final jitter result 0.0032 millisecond. Output throughput that too low and indicate that throughput is not sensitive towards the application that was used
