Optus, in collaboration with Ericsson and OPPO, have doubled down on 5G advancements by successfully carrying out a voice call over a commercial 5G standalone network.
Optus successfully demonstrated their first Evolved Packet System Fallback (EPS-FB) call which leads the way for what will become the next evolution in mobile calling. When launched commercially this technology will enable 5G standalone services to customers on smartphones, providing Optus customers with exciting new experiences and more innovative options they love.
The success of this technology milestone is a leap towards full deployment of Optus’ 5G standalone architecture nationwide, and we are already working on enabling 5G standalone voice calls using Voice over New Radio, said Optus.
This voice call was conducted on Optus’ network using EPS-FB, which utilised Ericsson Radio Access Network (RAN) technology, Ericsson cloud native dual-mode 5G Core for standalone networks, Ericsson Cloud IMS and Oppo’s Find X3 Pro 5G handset.
