Voice is still the king of communication in a 5G world and there will
be even more consumer and enterprise use cases developed where
high-quality voice and communication services experiences are crucial.
5G voice is the regular mobile phone call service that service
providers offers on 5G smartphones through Voice over NR(VoNR) and video
over NR (ViNR) technology. This may sound very basic, and from a user
point of view it is, you make voice calls on your new 5G devices like
you have always done on your mobile phone.
But for a service provider, there are a lot of mobile network
evolution aspects to consider behind the scene, to secure a high-quality
mobile voice service everywhere. To enable service provider voice calls
on 5G smartphones and other 5G devices, the network infrastructure used
for 4G voice (VoLTE) today will also be used to enable 5G voice calls.
What is the difference between 4G voice and 5G voice?
In 5G, the default voice codec in 5G smartphones enables “HD voice+”,
using the 3GPP standardized Enhanced Voice Services (EVS). EVS can
already be used in 4G networks, but is not mandatory. It provides a
greater voice quality experience than what narrowband voice and HD voice
provides today in 2G to 4G networks. It also provides better sharing of
music within a voice call, for example music announcements when queuing
at the help desk, or if you share music from a concert you are
attending.
What is VoNR and ViNR – Voice and Video over NR in 5G Voice?
Voice over NR and Video over NR is the target solution for voice and
video in 5G Voice. VoNR also often called Vo5G along with ViNR
technologies consists of a 5G RAN, radio access network, the 5G Core,
and IMS services where they all integrate together. Apart from high
quality voice and video calls with no buffer, these new technologies
will open up new type of capabilities that will enable new and enhanced
end-user experiences with a combination of voice services and live
streaming, real-time sensitive applications such as augmented reality,
collaboration and gaming. Higher codec rates can be used for voice and
video calls over 5G without consuming a substantial portion of the
cell’s capacity for mobile broadband.

· Improved speech quality with HD voice+
· Improved video calling quality
· New voice and communication services
· Simultaneous voice calls and 5G data services
Benefits for service providers
· Satisfy early 5G adopters - all smartphones with 5G data speeds also require voice services
· New revenue from 5G-specific voice and communication services for enterprises
Deep dive into 5G voice network evolution aspects
The journey to 5G has several mobile network migration steps, and
voice services must be supported in all evolution steps. The IMS (IP
Multimedia Subsystem) that is used for 4G voice (VoLTE) today will also
enable 5G voice. We have outlined several technical papers to help you
understand how to take today’s VoLTE based voice services into 5G,
explaining everything from the 3GPP standards based network evolution
aspects, to how Ericsson can support you with the commercial deployment.
Download today and take your deep dive into the mobile network
evolution aspects of 5G voice.
Listen to the episode with, David Bjore, Head of Solution Area
Communication Services for Ericsson explains how voice has never been
more important, especially in light of global challenges where
connection is vital and how 5G voice is changing our world and lift the
lid on where we are headed in the future.
With the introduction of 4G and 5G, service providers need to plan
for 2G/3G closure to reuse the spectrum and reduce costs. This white
paper provides recommendations on how to prepare for closure in the
Circuit Switching and IP Multimedia Subsystem domains.
All service providers must consider how to deploy mobile voice
services in 5G networks. Learn how in our guide to enabling 5G voice
services in mobile networks.
