ZTE trials VoLTE call service

China Mobile has teamed up with infrastructure vendor Huawei to demonstrate the world’s first international VoLTE HD voice and video calls between a TDD LTE network and a FDD LTE network

Chinese vendor ZTE is trialling a commercial VoLTE call service in Hong Kong.

The trial uses enhanced single radio voice call continuity (eSRVCC) , a voice solution that enables higher quality voice calls while the network is upgrading to LTE and provides end-to-end QoS assurance, the company said.

“eSRVCC VoLTE call improves connection time when compared to the CSFB solution and shortens handover time when compared to the SRVCC solution,” explained ZTE core network vice president Tu Jiashun.

“It gives LTE users more options and better service experience. The success of this solution is a milestone in the development of the VoLTE ecosystem.”
