US 9,807,644 B2 · Hierarchical traffic differentiation to handle congestion and/or manage user quality of experience

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.

Dependent claims

A method implemented in a base station, the method comprising:

receiving a user plane packet via a single tunnel established between the base station and a core network entity for a single packet data network connection, wherein the user plane packet comprises a header encapsulating a network layer packet associated to one particular traffic sub-class of various differentiated traffic sub-classes mapped to the tunnel, and wherein the user plane packet is extracted from a transport level packet having a header including an indication of a transport level quality of service (QoS) classification;
obtaining, from the header of the user plane packet, an indicator indicative of a particular policy of a plurality of policies for handling the various differentiated traffic sub-classes mapped to the tunnel;
and
applying the particular policy on the received user plane packet.
