LG Uplus says it has recently completed a test on 5G service in “standalone” mode on its commercial service network as part of its preparations for a shift in service from the current non-standalone mode.
Currently, LG Uplus, together with SK Telecom and KT, is providing 5G service in non-standalone mode, for which part of the LTE network, more precisely the control plane of the network, is used as well as the mid-band 5G network.
The use of the LTE network is blamed for a failure by the three mobile carriers to keep their promises to provide ultra-high speed, ultra-low latency and massive connectivity, which they made before they started 5G commercial service last year.
Now the mobile carriers are being pressured to start a new standalone service in a high band, or the 28 GHz band. But the problem is an exorbitant cost of service on the 28 GHz band, which would require new equipment and far more base stations than those being used for current service on the 3.5 GHz band.
When the Korean mobile carriers move to the high band, LG Uplus believes it will have a leg up in guaranteeing optimal 5G service characterized by ultra-high speed, ultra-low latency and massive connectivity, which it says will be required for virtual reality, self-driving and smart factories.
LG Uplus says it conducted a standalone test on the commercial 5G network in the Seoul area, connecting equipment in the base stations to the 5G packet core, or a framework for providing voice and data on the 5G network.
Moreover, it says it successfully tested equipment for the management of 5G subscriber information and the technology for network slicing, or slicing the original network architecture in multiple independent networks for various service requirements.
It says it developed the equipment and the technology jointly with its vendors, Ariatech and Telcowre.
The test on the commercial network, it says, included certifying 5G subscribers, sending and receiving data, devices crossing one cell to another -- all of them on the list of required verifications for commercial service in standalone mode.
The test followed an earlier one, which LG Uplus conducted on the connection of pieces of equipment produced by different manufacturers last November.
The two successful tests are testimony to LG Uplus being prepared to start a stable and high-quality service when subscribers start to use mobile devices in standalone mode, the 5G network carrier says.
“We will be able to provide both individual and corporate clients with diverse services at a time when they are in demand, guaranteeing them with optimal quality,” says Park Song-chul, an LG Uplus managing director who heads the NW technology group.
