Methods, systems and apparatus for managing and/or enforcing policies for managing internet protocol (“IP”) traffic among multiple accesses of a network
First Claim
1. A method comprising:
- obtaining, at a policy and charging rules function (PCRF) element, user plane congestion information associated with a radio access network (RAN); and
adapting, at a network element, a bearer used for transporting internet protocol (IP) traffic associated with a wireless transmit and/or receive unit (WTRU) based, at least in part, on the user plane congestion information and a rule specified by the PCRF element for enforcing a Quality of Service (QoS) policy.

Abstract
Methods, systems and apparatus for managing and/or enforcing one or more policies for managing internet protocol (“IP”) traffic among multiple accesses of a network in accordance with a policy for managing bandwidth among the multiple accesses are disclosed. Among the methods, systems and apparatus is a method that may include obtaining performance metrics associated with the multiple accesses. The method may also include adapting one or more rules of one or more the policies for managing IP traffic among the plurality of accesses based, at least in part, on the performance metrics and the policy for managing bandwidth among the plurality of accesses. The method may further include managing IP traffic associated with at least one wireless transmit and/or receive unit (“WTRU”) among the plurality of accesses responsive to the adapted rules.
