Mission Critical Services (MCS) are gaining interest among network operators to offer alternative communications than conventional trunked radio systems. They promise a simplified management of cloud and radio resources for service deployment. However, the network capabilities should be adapted for the changing conditions, to assure low-latency and reliability for such applications. This paper presents an on-going work on utilising 5G technology for Mission Critical Push To Talk (MCPTT) services. It describes some design elements and evaluates 5G ESSENCE architecture that enable mission critical applications.
