South Korean carrier LG Uplus completed tests of core technologies supporting voice service running on a standalone (SA) 5G network as the carrier expects to launch 5G based on SA architecture later this year.
In a statement, the operator said the tests verified the performance of evolved packet system (EPS) fallback and voice over 5G (Vo5G), and demonstrated it is ready to deliver stable and high-quality 5G voice services.
“We succeeded in securing core technologies for the commercialization of 5G standalone mode through this commercial test,” said LG Uplus’s network technology unit head Park Song-cheol.
