Abstract
A Packet Control Function (PCF) may not have enough knowledge about packet data arriving on a bearer path via a Packet Data Serving Node (PDSN) to appropriately decide how best to handle the packet data. Thus, the PDSN may provide bearer-specific information by encapsulating the packet data within the payload of a Generic Routing Encapsulation (GRE) frame, and for a requested feature, setting a protocol-type field in the header of the GRE frame indicating that the packet includes an attribute field, and adding an attribute field to the payload of the GRE packet to provide attribute data corresponding to the requested feature. The PCF may send an A-11 request to the PDSN indicating which features the PDSN is requested to enable. For example, for short data indication, the PCF may request the PDSN add to the GRE frame an attribute field containing attribute data indicating when a Short Data Burst is suitable.
