Abstract
As part of mobility management messaging in current systems, only static quality of service (QoS) profiles and their statically configured classifiers are reported. These classifiers are known a priori and are typically used for hosted traffic. Once advanced application classifiers are matched and mobility messaging is done, the deep packet inspection (DPI) learned subscriber context is lost. An embodiment of the invention is configured to associate DPI-learned dynamic classifiers with the classifier's policy information as payload over mobility management messaging. The embodiment is useful for identifying protocols and applications, for authentication purposes, solving congestion-based issues between elements in a network, guaranteeing QoS without reserving resources statically, attaching traffic packets to a particular subscriber, and creating mobile signaling to provision end-to-end communication in a network. Thereby enabling the transfer of subscriber parameters and information to be associated with the subscriber throughout subscriber movement through multiple elements of a network.
