SK Telecom announced on Nov. 25 that it has successfully developed two core technologies related to network virtualization, widely acknowledged as essential for a 5G network.
Korea’s largest mobile carrier explained that it will be possible to easily and rapidly introduce and improve new services based on software when everything from core networks to base stations is virtualized, unlike the existing method that introduces services through the development of separate hardware.
The newly-developed technology called “Orchestration” is able to provide telecommunications services to consumers on a virtualized network. The technology makes it possible to maximize efficiency by combining several features of virtualized networks, and developing or building telecommunications services like LTE for the Internet of Things (IoT), or a national disaster safety communications network based on software.
The carrier stresses that it has also succeeded in developing a cloud virtualized Radio Access Network (Cloud vRAN), a core technology for the development of next-gen base stations, in partnership with Nokia. The existing technique can virtualize only the core network, but the new technology is able to virtualize the entire communication network, including base stations, based on a cloud environment.
The technology will make it possible to operate networks more efficiently, since virtualized communications functions can be created, changed, or managed more easily. When an error occurs in a communications network, the new technology can greatly reduce the time needed to discover the error and recover the network through an auto recovery feature.
