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.

Abstract translation: 分组控制功能（PCF）可能不具有关于通过分组数据服务节点（PDSN）到达承载路径的分组数据的足够的知识，以适当地确定如何最好地处理分组数据。 因此，PDSN可以通过在通用路由封装（GRE）帧的有效载荷内封装分组数据来提供承载特定信息，并且对于所请求的特征，在GRE帧的报头中设置协议类型字段， 分组包括属性字段，并且向GRE分组的有效载荷添加属性字段以提供对应于所请求的特征的属性数据。 PCF可以向PDSN发送A-11请求，指示PDSN被请求启用哪些特征。 例如，对于短数据指​​示，PCF可以请求向GRE帧添加包含指示短数据突发何时适合的属性数据的属性字段的PDSN。
