Is cloud-native IMS critical for our 5G future?

IP multimedia core network subsystem (IMS) is the underlying standard for IP voice supported by vendors and operators worldwide. It is the foundation for IP-based services including fixed-line consumer voice, VoLTE, VoWiFi, and Rich Communication Services (RCS), as well as 5G voice and messaging.

The growth of IMS has increased with the launch of VoLTE across all regions in the past five years and as operators worldwide continue the move to IP and large network modernization projects. Expansion with mobile operators through VoLTE and VoWiFi is fueling the growth of IMS today and the migration to 5G voice and messaging will fuel continued growth, according to this paper from IHS Markit, commissioned by Mavenir.

The paper includes several real-world use cases from around the world, including Asia.
