摘要

在本文中,我们提出了一种流媒体服务在系统间切换时的自适应缓冲方案。流媒体服务的缓冲方案通常用于补偿网络的延迟抖动。这样,作为无线通信系统服务的终端,可以探索在切换过程中停止接收流数据包的问题。特别是在系统间切换时,接收报文的中断时间比系统内切换的中断时间长。因此,现有的缓冲方案不能完全补偿QoS的降低。本文提出的方法是在切换前附加缓冲方案。使用该方法可以防止流媒体服务在切换过程中中断。通过仿真验证了该方法的有效性。

Adaptive buffering scheme for streaming service in intersystem handover between terrestrial and satellite systems
In this paper, we propose an adaptive buffering scheme for streaming service during inter-system handover. In general, the buffering scheme of streaming service is used to compensate for delay jitter of networks. By the way, the terminal, which is served from wireless communication systems, can explore the discontinuation of receiving streaming packets during handover. Especially, in case of inter-system handover, the discontinuation of receiving packets is longer than that of intra-system handover. Therefore, existing buffering schemes cannot fully compensate for the degradation of QoS. The proposed method of this paper is an additional buffering scheme before handover. Using this method, we can prevent the discontinuation of streaming service during handover. This method is validated through simulations.
