Revenues for the cloud-native IMS VoLTE core will accelerate in 2019 to more than 60 percent growth over 2018 and Nokia remained the number one vendor in 3Q18 in this segment, according to a recently published report from Dell’Oro Group.

“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,” stated David Bolan, Senior Analyst at Dell’Oro Group. “The same IMS VoLTE core will be used in 5G, paving the way for a more robust and resilient network.”

“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. 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,” Bolan continued.

 - Nokia maintains number one ranking, followed by Huawei, Ericsson, and ZTE.

 - VoLTE in the Asia Pacific region rose to nearly half of the worldwide licenses.

 - New VoLTE-based devices are gaining traction in smartwatches, voice over Wi-Fi (VoWiFi), voice on IoT (LTE Cat-M1), and video calling over LTE (ViLTE).
