What is 5G voice?

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.

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.
