1O1O and one2free turn on VoLTE network across Hong Kong

Telecom operators 1O1O and one2free today (5 December) launched the first VoLTE (Voice over LTE) network in Hong Kong powered by Hong Kong’s Trusted Network and supported by ZTE’s 4G solutions. The full commercial launch is expected to take place in the first half of 2014, in line with projected device maturity in the market.

CSL’s VoLTE offers instant connection and better quality video calls enabled by ZTE’s IMS (IP Multimedia Subsystem) solution. The opportunity for voice calls to be made on 4G means customers will experience a clearer voice and richer multimedia experience, with a distinct improvement in video call quality.  VoLTE also allows 1O1O and one2free to achieve better spectral efficiencies and will increase network capacity and subsequently enhance the 4G LTE experience.

“The availability of the VoLTE device to our customers in the first half of next year will reinforce our position as the leading 4G LTE mobile operator in Hong Kong,” said Phil Mottram, chief executive officer of CSL. “We are proud to deliver a trusted network that offers impressive speed, stability and broader coverage throughout Hong Kong and that carries a brand new enriched voice and video experience for our customers.”

ZTE’s IMS solution supports enhanced single radio voice call continuity (eSRVCC ), delivering smooth handovers between voice calls on 4G and 3G networks for CSL’s VoLTE service. Customers can also access CSL’s best in-class 4G mobile data services simultaneously, while conducting VoLTE calls ensuring improved usability and a high-quality experience. Customers will also be able to enjoy faster call setup speeds compared with 3G.

“We have worked closely with CSL to deliver this state of the art VoLTE service to its customers, and will continue to maintain CSL’s leading network position in the Hong Kong market,” said Shi Lirong, president of ZTE.

1O1O and one2free are further enhancing their 4G network experience in the Mass Transit Railyway (MTR). The upgrade of its LTE 1800MHz spectrum from 10MHz to 15MHz on the islands, Tsuen Wan, Kwun Tong, Tseung Kwan O and Tung Chung lines was completed in early December and will be extended to cover all MTR lines by the end of 2013 subject to MTR’s schedule. This will give 1O1O and one2free a superior network experience on speed and capacity.
