The outlook for IP Multimedia Subsystem (IMS) Voice over LTE (VoLTE) is positive. This is outlined in a Dell’Oro group report, which forecasts revenues for the cloud-native IMS VoLTE core to accelerate in 2019 to more than 60% growth over 2018. In 3Q2018, Nokia lead the global market.
“Moving to the cloud with cloud-native software is now a material part of the IMS VoLTE core revenue as service providers prepare their networks for 5G. The same IMS VoLTE core will be used in 5G, paving the way for a more robust and resilient network,” stated David Bolan, senior analyst at Dell’Oro Group.
“The VoLTE outlook for 2019 looks bright with several announcements during the quarter: Nokia is upgrading part of China Unicom’s VoLTE network, T-Mobile will use Ericsson as one of their VoLTE suppliers, and Telefónica Deutschland selected Mavenir for a VoLTE upgrade,” Bolan continued.
“These are multi-year modernization contracts transitioning to cloud-native virtual network functions in order to support more cost-efficient network operations, enabling faster scaling of capacity as well as faster deployment of new services in LTE and 5G.”
