Immersive media applications demand both a huge amount of data processing and low latency. The former requirement can be fulfilled by offloading user equipment (UE) tasks to a baseband unit (BBU) pool (or data center). As for the low latency, it can be achieved with Mobile Edge Computing (MEC), which allows offloading the tasks close to the UEs. In this paper, we take advantage of the cooperation between conventional BBUs and MEC to handle the UE tasks. Specifically, we propose an orchestration framework and a protocol to enable seamless immersive media applications. Our extensive simulations show that our solution can significantly reduce the number of failed tasks.
