Real time testbeds for 5G NSA and SA mobile architectures to provide VoLTE and VoNR services over IP Multimedia Core Network Subsystem

The contribution of this work is the deployment of real time testbeds for the 5G NSA (Non-StandAlone) and the 5G SA (StandAlone) mobile architectures to provide both Voice over LTE (VoLTE) and Voice over New Radio (VoNR) services. In addition, an IMS (IP Multimedia Subsystem) core network was deployed to provide voice over IP services. The delay, the throughput and the jitter quality of services metrics are also computed, which allow analyzing and comparing the results between both 5G network architectures.
