Real-time communications are services with very demanding requirements in terms of reliability and Quality of Service (QoS), that is not easy to be reached. 5G technologies provide tools and techniques that promise to overcome the current shortcomings and thus give the opportunity to service providers to offer better experience to the end users. This paper aims at describing how an existing real-time communication service can leverage the innovative features offered by the SONATA Service Platform (SP), such as network slicing, automated monitoring management and Service Level Agreement (SLA) enforcement, to meet the challenging requirements of the service. In this paper, we especially focus on the specific mechanisms implemented to support different QoS profiles at network level and automatic scale in/out of the service depending on the system load.
