When i make video call does it require QCI 1, and QCI 2 bearer?

Question

Because video call involves videos and audio so does it require 2 bearer or single bearer?

Answer 1

Hi,

video or audio call it is upto encoder and decoder,for the LTE stack it is just an IP packet so it doesn't need an multi bearer for video cal.when you make an video call your skype or IMO application will make one IP packet and forward it to LTE stack so LTE stack does not have knowledge on the content so single bearer is enough to forward IP packet.
