The Use Case aims to address the need for coordination between Public Protection and Disaster Relief (PPDR) agencies by implementing a dynamic solution based on location or network conditions. It also seeks to explore Quality of Service (QoS) management and slicing for MCX communications. To this end, a fully microservices-based MCX solution has been developed, fitting with the cloud-native nature of the 5G-EPICENTRE platform. This technology, used in both the MCX solution and the 5G-EPICENTRE platform, will increase deployment agility, enhancing the experimental needs raised in this UC.
