Abstract

A serving GPRS node (SGSN) is made content aware by passing content based rate information in the GPRS tunnel protocol (GTP) header. The SGSN uses the PDP context request to inform a GPRS support node (GGSN) that it is content aware and can process the content based rate information. In one embodiment, the rate information is passed in a GTP extension header. A new GTP header type tells the SGSN that rate information is present in the GTP header content field. In an alternate embodiment, the rate information is passed in a fourth octet of a four octet tunnel endpoint identifier (TEID).
