South Korea’s smallest mobile network operator by subscriber, LG Uplus, has launched voice-over-Long Term Evolution (VoLTE) services in partnership with Swedish vendor Ericsson’s local subsidiary LG-Ericsson. Ericsson confirmed that it had supplied an end-to-end VoLTE network to LG Uplus to facilitate the service launch, including LTE-RAN, Evolved Packet Core, and IMS Telephony Application Server. Commenting on the development, Joo sik Choi, Senior Vice President of Service Creation at LG Uplus, noted: ‘Improving the user experience for our subscribers is always our top priority. Ericsson’s global leadership in LTE technology and experience in building an end-to-end LTE network infrastructure helped ensure the success of the nationwide launch of this service.’
As noted in TeleGeography’s GlobalComms Database, LG Uplus in April 2012 claimed it had become the first South Korean cellco to complete the nationwide rollout of its LTE infrastructure, having initially launched services back in July 2011. At the end of June 2012 LG Uplus reported that its LTE subscriber base stood at 2.576 million.
