In a press release, 3 Hong Kong confirmed that the trial involved S8 Home Routed (S8HR) architecture, an LTE data roaming-based technology that can be deployed without IP Multimedia Subsystem (IMS) interaction between parties. The cellco confirmed that the S8HR platform ‘enables VoLTE roaming service to be made available in fast-track fashion’ to deliver superior HD voice and video roaming on a suitably enabled device. With the trial completed, the pair now aim to deliver commercial VoLTE roaming in Hong Kong and Japan.
