Abstract: The Packet Control Function (PCF) has limited knowledge about the nature of the packet data arriving on a bearer path connected via the Packet Data Serving Node (PDSN), and cannot make an intelligent decision on its own as to how best to handle the packet data. Thus, the PDSN provides bearer-specific information by classifying the priority of received packet data; encapsulating the packet data within the payload of a Generic Routing Encapsulation (GRE) frame; and for high priority packet data i) setting a protocol type field in the header of the GRE frame indicating said packet includes an attribute field; and ii) adding an attribute field to the payload of the GRE packet which provides an indication of said high priority data. Furthermore, the PCF can send an A-11 request to the PDSN indicating the features that the PCF is requesting the PDSN enable. For example, for a short data indication, the PCF would request the PDSN enable adding the attribute field to the GRE frame when an Short Data Burst (SDB) is suitable.

Abstract: A method and system for achieving a link budget improvement in a diverse OFDM radio system by addressing the timing misalignment issue that can occur due to the differences in propagation time in signals between mobile stations and Radio Access Nodes. Timing misalignment is shared or split between the primary path to a primary Radio Access Node and a diverse path to a diverse Radio Access Node. The relative timing offsets between mobile stations are adjusted, the mobile stations are grouped into zones using a variety of different grouping techniques, and the transmission for each mobile station is scheduled, using one or more of a variety of scheduling techniques.

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.
