    Step2 in 2016,  it will be carried out about large scale network construction, tests and adjustments in the chips, devices, networks, services, interconnection and interworking, IT and other aspects;
    Step3 in the end of 2017,service commercialization will be achieved.

    It is a long-term process for China Telecom to do migration CDMA to VoLTE  because China Telecom still has nearly 200 million subscribers in the CDMA live network and the CDMA and LTE networks will coexist in China Telecom.
