Abstract

In this paper we present Joint Unicast-Multicat Panoramic Streaming (JUMPS) over the cellular network. JUMPS optimizes the resource allocation for a group of eMBMS (evolved Multicast Broadcast Multimedia Systems) users to enhance their experience while leveraging the inherent diversity in both users’ network conditions and field of view (FoV). The key intuition is combining unicast and multicast, for tiled panoramic content, would enable facilitate using the right amount of resources for every tile considering the tile popularity and receiving user link quality. We compare JUMPS performance to state-of-the-art solutions and show that it significantly improves users’ received FoV bitrate and reduces their battery by reducing the number of resource blocks that users have to listen to. These results are consistent across various scenarios that vary across user group link conditions, FoV diversity, and available network resources.
蜂窝网络中优化的联合单播-多播全景视频流
在本文中,我们提出了联合单播多路全景流(跳)在蜂窝网络。jump优化了eMBMS(进化的多播广播多媒体系统)用户的资源分配,在利用用户网络条件和视场(FoV)的固有多样性的同时增强了他们的体验。关键的直觉是将单播和多播结合起来,对于平铺全景内容,考虑到平铺的受欢迎程度和接收用户链接的质量,可以方便地为每个平铺使用适量的资源。我们将跳跃性能与最先进的解决方案进行比较,并表明它显着提高了用户接收的FoV比特率,并通过减少用户必须收听的资源块数量来减少电池电量。这些结果在不同的场景中是一致的,这些场景因用户组链路条件、FoV多样性和可用网络资源而异。
