A packet gateway (PGW) receives a plurality of IP packet fragments from a network. The IP packet fragments comprise a head fragment and one or more trailing fragments, and are associated with a first IP packet. As the fragments are received, a controller at the PGW classifies the fragments. The controller applies a same selected service treatment to the head fragment and to each of the trailing fragments based on the classification of the head fragment. The PGW then sends each treated packet fragment to an end user device.
