I haven;t talked much with mobile network operators. One data
point a US mobile operator gave me was about recognizing certain 
type p2p traffic that had real bad congestion control and was
monopolizing congested links. And then counter that. I am not sure
if this policing happened on some mobile link/path-segment or at
the edge to the non-mobile core.

Cheers
