| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Since smartphones have spread and the transmission rate of mobile networks has accelerated, a lot of VoIP services are provided on mobile networks. Voice quality degradation due to delay spikes, the sudden large increase of the packet delay, is the key issue for VoIP on mobile networks. For this issue, adaptive jitter buffer control methods considering delay spikes have proposed. This paper presents a delay spike reduction method by controlling size and interval of voice packets for further improvement of the quality of voice communications. Simulation results on the network simulator (ns-3) show the presented method reduces the number of delay spikes more than 50% and the method is effective in order to improve the quality of voice communications. | |
