Abstract
Methods, apparatuses and systems for performing hierarchical traffic differentiation and/or employing hierarchical traffic differentiation are provided. These methods, apparatuses and systems may be implemented to, for example, handle congestion and/or to manage user quality of experience (QoE). Performing the hierarchical traffic differentiation may include differentiating or otherwise classifying (collectively “differentiating”) traffic mapped to, or within, a bearer formed in accordance with a QoS class into multiple traffic sub-classes. Employing the hierarchical traffic differentiation may include scheduling and/or policing (e.g., filtering) the differentiated traffic for transmission based on a prioritization of, and/or policy for managing, the multiple traffic sub-classes.
