Handling Mission Critical Calls at the Network Edge

摘要

In fifth generation networks, Multi-access Edge Computing (MEC) enables deployment of applications with requirements for low latency and high reliability. In this paper, we propose an approach to handle mission critical calls using MEC technology. The approach is illustrated by typical use cases, data model, interface definition and call state models which are formally verified. The main advantage is that the approach does not require deployment of Internet Protocol Multimedia Subsystem at the network edge.
