Updated:2015/7/7 10:32

Wang Xiaochu, the Chairman of China Telecom, officially released the roadmap for VoLTE on the "2015 Tianyi (E-surfing) Terminal Expo & Summit Forum", China Telecom planned to make its 4G network reach the same coverage levels of its Tianyi 3G network and launch VoLTE by the end of 2017.

The schedule for implementation of China Telecom VoLTE is planned to be: the operator will implement technology tests and verification, technical specification and program development in 2015; large scale network construction, tests and adjustments in the chips, devices, networks, services, interconnection and interworking, IT and other aspects will be carried out in 2016; service commercialization will be achieved by the end of 2017.

For the device industry chain, the determination of VoLTE schedule provided a good guide, at the same time, it brought huge pressure. On July 4th, the deputy general manager of China Telecom Market Department Lu Liangjun said in facing the industry chain, judging from the roadmap, China Telecom will steadily push forward the VoLTE. However, this doesn’t mean that China Telecom will shut off CDMA soon and shift to VoLTE. In fact, China Telecom still has nearly 200 million subscribers in the CDMA live network, which is a hard task for migration. For a long time, the CDMA and LTE networks will coexist in China Telecom and the migration will be a long-term process.

Lu Liangjun stressed that the put forward of VoLTE roadmap actually clarified another thing, namely China Telecom will strive to develop the 4G network coverage, because network coverage is the premise of VoLTE commercialization.

When talking about the changes that VoLTE brought, the deputy general manager of China Telecom Technology Department Shen Shaoai said that China Telecom learnt from the experiences from Verizon in considering the voice solution programs, which is the largest mobile operator in America. China Telecom will not choose the CSFB solution program. In 2016, China Telecom will mainly launch the SRLTE+VoLTE terminal model. At the same time, VoLTE will obtain priority in the voice services. In the subsequent evolution, China Telecom will achieve “multi-modes without CDMA”, and realize only VoLTE voice service.
