I need to verify some claims made by incumbents in Canada that VoLTE data travels on a totally separate channel between the phone and the antenna.
Typically it travels on another "bearer" compared to Internet traffic. http://blog.3g4g.co.uk/2013/08/volte-bearers.html Think of bearers as "tunnels" between the mobile core network and the device. They have a lot in common with ATM PVCs in that they can have different QoS characteristics. So the VoLTE bearer can have scheduling priorities that means it'll always be low-latency and highest priority, meaning it might work well when the "Internet" bearer does not. -- Mikael Abrahamsson email: swmike@swm.pp.se
