How does the UE receive a second call during an actice VoLTE session?
It doesn’t listen to paging, so how MME informs UE?
In connected mode you are not paged.
I believe there is NAS message to inform of incoming service request and NW proceeds with any necessary bearer setup procedure, should the UE accept the request.
As network know the UE at cell level so no need to page for second call.
Yes but how the UE will be informed of the second call?
Inside NAS?
