Digital Nasional Berhad (DNB) and Ericsson (NASDAQ:ERIC) recently demonstrated a 5G Voice over New Radio (VoNR) call, conducted in Malaysia for the first time over a live 5G network. This technical achievement is a testament to the ability of the DNB network to support non-standalone (NSA) and standalone (SA) 5G architectures.
VoNR uses DNB’s 5G network architecture to provide end users with a high definition voice and video experience thanks to ultra-fast 5G speeds for the duration of calls. VoNR is also expected to generate new revenue opportunities among mobile network operators with 5G-ready cores. Calls were made over the live network using OPPO Find X3 Pro phones.
Currently, voice and/or video calls made via mobile devices are dependent on existing 4G LTE networks. Thus, devices on the 5G network will switch to 4G LTE by default. Now, compatible devices that support VoNR capabilities are no longer handed over to the 4G network to make calls. This greatly reduces network switching for devices on the 5G network.
As a result, devices on a 5G network will soon be able to perform VoNR calls and large file downloads simultaneously without any interruption due to network switching.
The superior characteristics of 5G radio will enable the improvement of voice and communication services, such as network video calling, real-time interaction, and further development of voice calls into rich and innovative communication services.
These services can take advantage of the high data speeds and low latency of 5G, to enable new real-time voice and communication use cases between humans, or between humans and machines; For example, interactive communication, augmented reality, virtual reality and other services.
In addition, an increase in audio and video capacity has been achieved due to the increase in audio and video calls per cell in crowded city areas.
Ken Tan, Chief Technology Officer of Digital National Berhad, said, “The successful VoNR demonstration, which was conducted for the first time over a live 5G nationwide network, is the latest technical milestone for how 5G can deliver new and superior user experience via cloud-native 5G autonomous architecture. “5G VoNR can be a key enabler for immersive next-generation applications that combine 5G speeds with high-resolution voice. We will continue to bring 5G capabilities to support technological innovation in Malaysia.”
David Hägerbro, Head of Ericsson Malaysia, Sri Lanka and Bangladesh said: “5G VoNR calls are the core capability needed for future SA NR (SA NR) 5G deployments and will allow innovative services to be introduced in the market. This is another milestone as we work with DNB to deliver a global network level for Malaysians to enjoy.”
Earlier in November 2021, DNB’s multi-core operator network (MOCN) architecture achieved a global technical achievement, becoming the first operator to successfully integrate a 5G wireless access network (RAN) with five domestic operators.
