Recently, the high bandwidth and the guaranteeing QoS are required to support the increasing demands for multimedia services. Telecom companies release LTE service, 3GPP standard technology to solve such a demand. In order to use the downlink resource and support the QoS efficiently, the packet scheduling scheme is one of the important technical issues in LTE system. Especially since LTE provides the QoS for downlink packets with various service class, it is important to control the priority of them to satisfy customer's QoS policy. In this paper, we propose the controller module for increasing the QoS of multimedia service and analyze the experiment result. the proposed scheme utilizes the waiting time of transmission queue, the maximum allowable delay, and the status of receiving buffer. The experiment shows a better performance of throughput and transmission delay.
