Hong Kong's CSL has activated VoLTE in its network using ZTE's 4G and IMS solutions. The full commercial launch is expected to take place in the first half of 2014.
ZTE’s IMS solution supports eSRVCC (enhanced Single Radio Voice Call Continuity), delivering smooth handovers between voice calls on 4G and 3G networks for CSL’s VoLTE service. Customers can also access CSL’s 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 for the Hong Kong market,” said Shi Lirong, President of ZTE.
