5G for the Support of Public Safety Services

Abstract Next-generation mobile technologies are the enablers for meeting variable specific requirements of public safety (PS) community. In particular, due to development commercially deployed 5G networks, PS providers look ways implement related solutions upon such infrastructures, potentially in a shared use with existing commercial networks. LTE and NR networks rapidly gaining recognition as an all-inclusive critical communications platform delivery both mission business applications. Within this scope, we take into account innovative architectural approach that has been proposed by ESSENCE project, addressing paradigms edge computing small cell as-a-service realised via cloud-enabled infrastructure leveraging multi-access 5G, where propose dedicated case, able offer push-to-talk service well Chat Localisation service. Each one these services is associated network slice within scope corresponding fundamental architecture provided suitable VNFs, thus offering great flexibility serve needs together. We further discuss overall scenario deployment technical functionalities, per case . The end-to-end slicing makes possible allocate radio cloud resources involved actors, automated elastic way.
