ZTE says that it has helped China Mobile deploy voice over LTE (VoLTE) services on the operator's commercial TD LTE network in Guangzhou as a step to a wider nationwide rollout.
The VoLTE services on China Mobile's network supports enhanced Single Radio Voice Call Continuity (eSRVCC) switching for seamless handovers to non-4G networks.
The VoLTE deployment in Guangzhou was also enabled by a newly-built IP Multimedia Subsystem (IMS) system provided by ZTE.
"The successful demonstration of VoLTE service speeds up the development of the entire industry ecosystem," said Mr. Sha Yuejia, Vice President of China Mobile. Mr. Sha and Ms. Wang Xiaoyun, general manager of the Technical Department of China Mobile conducted video calls as they experienced the VoLTE service in a vehicle in the urban area of Guangzhou. They also witnessed the capabilities of ZTE's eSRVCC solution when voice calls were seamlessly handed off from 4G networks to third-party 2G networks, a key to future commercialization of the service.
The successful VoLTE deployment by China Mobile was completed using network systems and terminals used from different vendors, which shows the feasibility of eSRVCC for all networks of China Mobile.
