With the rapid growth of OTT platforms and, the wide-range and chronic use of mobile apps, operators need to expand their business service tunnels to seek a breakthrough in the market, thus they set their sights on 5G new calling and text messaging.
5G new calling, VoNR+, is an enhanced version of Voice over New Radio (VoNR), which can provide high-quality voice call service over 5G networks. Rather than VoNR, VoNR+ can offer several additional functions and support more innovative applications with diversified customer experiences.
VoLTE and VoNR are both multimedia services enabled by the IP Multimedia Subsystem (IMS). They rely on the establishment of a large channel (including small channels for audio, video, and signaling) between terminals and IMS through the 4G/5G network.
5G VoNR+ builds on this foundation by introducing a new channel called the Data Channel (DC) in addition to the existing channels. On the basis of traditional IMS, VoNR+ upgrades the existing network elements to support 5G high-performance networks, and comprehensively moves towards 5G Service Based Interface (SBA) architecture. The specific services are developed by third parties and carried on IMS DC channels.
The DC is designed to provide more efficient data transfer for voice and video calls, enabling faster call setup times and improved call quality. This new channel can be used to transmit various forms of data such as text, images, videos, files, location information, actions, drawings, menus, VR/AR, and more. It means that the DC of VoNR+ not only supports higher quality voice and video calls, but also provides users with more functions and services.
For example, users can share photos, files, and location information during calls, engage in real-time drawing and VR/AR interactions, or use menus for quick voice control. Some of these application scenarios includes:
• Video Customer Service
• AI Voice Recognition
• Intelligent Real-time Translation
• Screen Sharing/Remote collaboration
These innovative functions and services will further drive the development of mobile communication and provide users with more diverse and enriching experiences.
Looking ahead, as 5G networks continue to be deployed and expanded around the world, VoNR+ is likely to become more widely available and adopted. As more users switch to 5G networks, the demand for high-quality voice and video calls is likely to increase, making VoNR+ a valuable opportunitiy for mobile network operators, while it is still a considerable challenge due to several factors such as user behaviour and industry ecosystem.
