While the support of Mission Critical (MC) communications on commercial cellular networks has already been incorporated in the latest releases of Long Term Evolution (LTE), it is expected that the network slicing feature of Fifth Generation (5G) systems will further boost the provision of these services thanks to the possibility of creating customized and isolated network slices adapted to the specific requirements of MC communications. At the Radio Access Network (RAN), the realization of a network slice requires to specify how the pool of available radio resources is split between the different slices in accordance with their service requirements. In this context, this paper addresses the use of RAN slicing for provisioning MC services taking as a reference the emergency scenario defined by the 5G ESSENCE project. It is characterized by different stages associated to the occurrence of an incident and its evolution, thus involving different communication needs. For each stage, an estimation of the capacity requirements to be granted to the MC RAN slice is provided. Then, the architecture of the project is discussed, focusing on the components that enable the RAN slicing management to properly support MC services.
