If the phone is in idle, I believe the GTP tunnel changes status as well
so also SGSN/GGSN is involved.
I'd imagine the transport network between all the devices can affect time
as 3GPP likes to reserve resources everywhere, so it might be that a lot
of transport network devices could potentially be included as well.
