Support for Edge Computing in the 5G Network

Networks beyond 2020 are required to support diverse use cases. Among the emerging services, support of delay critical mobile applications require network enhancements to natively offer low latency and high mobility. In this regard, the 5G network needs to be flexible for new service scenarios, and MEC can be supported to reduce the latency. In this paper, we present the feature of support for MEC in the 5G network and explain working mechanisms for application allocation, user plain selection, traffic local routing and steering.
