Abstract

The standardization of 5G wireless next generation networks is planned to be started by 3GPP consortium in 2020. Nevertheless, for today, there is the lack of QoS related 3GPP and ITU-T recommendations describing various popular services, for example video conferencing. The problem is to find the optimal bit rate values for this service not affecting the background lower priority services. In this paper, we propose a tool to solve this problem. The tool includes, first, a mathematical model of pre-emption based radio admission control scheme for video conferencing and background video on demand, and second, an effective algorithm for calculating QoS parameters for these services. The results of the paper could be used to find the optimal bit rates for video conferencing and further develop a proposition for standardization activities in video conferencing recommended parameters. ∗The reported study was partially supported by RFBR, research project No. 13-07-00953.

下一代无线网络中视频会议和视频点播业务的QoS参数计算算法

5G无线下一代网络的标准化计划由3GPP联盟在2020年启动。然而，就目前而言，缺乏与QoS相关的3GPP和ITU-T建议来描述各种流行的服务，例如视频会议。问题是如何在不影响后台低优先级服务的情况下为该服务找到最佳的比特率值。在本文中，我们提出了一个工具来解决这个问题。该工具首先包括基于抢占的视频会议和背景视频点播无线准入控制方案的数学模型，其次是计算这些服务的QoS参数的有效算法。本文的研究结果可用于寻找视频会议的最佳比特率，并进一步为视频会议推荐参数的标准化活动提出建议。(*)本研究得到了RFBR(13-07-00953)的部分资助。信息通信技术学报，Vol. 3, 3 - 28。doi: 10.13052 / jicts2245 - 800 x。311 c©2015 River Publishers。版权所有。4 V。Y. borodaki等。
