Voice in 5G in an Hour

CONTENTS This course is a brief technical presentation of the handling of multimedia telephony service in 5G (with standalone deployment) and related interworking procedures with 4G, as specified in the 3GPP standards. The course focuses on the voice/multimedia telephony service under IMS control for networks with 5G deployed. It presents the architecture for IMS-based call handling in 5G networks, the interworking between 4G and 5G on the core network and radio network level to support device mobility and service continuity in a multi-access environment and selected requirements as specified by GSM Association. PREREQUISITES Technical knowledge of the voice service handling in 4G mobile telecom networks is crucial. Understanding the technical solutions for the handling of the voice service in 5G requires a good grasp of voice handling in 4G (VoLTE, with IMS control) and the general 5G network architecture.
