Efficient and Flexible Point-to-Multipoint Content Distribution in 5G and Beyond

该项目旨在研究支持基于5G及以后网络的多媒体内容点对多点传播的新技术。自2019年推出以来，5G已经能够提供增强的用户体验，特别是在实时多媒体应用中。但是，许多多媒体直播内容需要同时传输到大量终端用户设备上（如体育赛事直播），这在网络效率上还没有得到5G的很好支持。为了解决这一关键技术问题，本项目的目标是设计、实现和评估新的算法和机制，以便在5G网络基础设施（包括5G无线电）上实现点对多点多播技术和协议，从而同时提高用户体验质量（QoE）和网络效率。将在项目中进行基于模拟/测试平台的实验和评估。

This project is to investigate novel techniques for supporting point-to-multipoint dissemination of multimedia content based on 5G and beyond networks. Since its roll-out in 2019, 5G has been able to offer enhanced user experiences especially in real-time multimedia applications. However, many live multimedia content needs to be simultaneously transmitted to a large number of end user devices (e.g. live sports events), which has not yet been well supported by 5G in terms of network efficiency. To solve this key technical issue, the target of this project is to design, implement and evaluate novel algorithms and mechanisms for enabling point-to-multipoint multicast techniques and protocols over 5G network infrastructure (including 5G radio) in order to simultaneously improve user quality of experiences (QoE) and network efficiency. Simulation/testbed based experiments and evaluations will be carried out in the project.
