LG U+ to launch Korea’s second VoLTE service

LG U+ is set to become the second operator in South Korea to launch voice over LTE (VoLTE) services through a partnership with Ericsson’s subsidiary LG-Ericsson.

The announcement follows a VoLTE launch by SK Telecom earlier this month, and it is likely that the two will interconnect the service to allow customers on both networks to make LTE calls to each other.

VoLTE enables voice calls to be made over an LTE network, while allowing users to access high-speed mobile broadband services at the same time. Previously CDMA-LTE devices required a simultaneous CDMA and LTE connection to make voice calls.

Through the technology, LG U+ will also be able to offer enhanced services including HD voice, video calling, chat and presence.

"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," says Joo sik Choi, SVP of service creation at LG U+.

Ericsson previously supplied LG U+ with its LTE network, including LTE-RAN, evolved packet core and IMS telephony application server.

"With the new VoLTE technology, LG U+ will be able to offer its subscribers better voice quality and an improved user experience. The new VoLTE services will sharpen LG U+'s competitive edge considerably and will provide the foundation for further enriching their communication services offering," said Johan Wibergh, head of business unit networks at Ericsson.

LG U+ was the first operator to commercially launch LTE services in Korea on July 1 2011. The company is South Korea’s second largest LTE provider with 3.1 million subscribers.
