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:
- receiving, at a policy and charging rules function (PCRF) element from an information collection and reporting element of a core network, user plane congestion associated with a radio access network (RAN);
obtaining, at the PCRF element, subscription information associated with one or more wireless transmit and/or receive units (WTRUs); and
adapting, at a network element, a bearer used for transporting internet protocol (IP) traffic associated with one of the WTRUs based, at least in part, on the user plane congestion information, the subscription 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.

22. A system comprising a policy and charging rules function (PCRF) element, and a network element, wherein:
-
the PCRF element is configured to; receive user plane congestion information associated with a radio access network (RAN) from an information collection and reporting element of a core network; and specify a rule for enforcing a Quality of Service (QoS) policy; and the network element is configured to; transport internet protocol (IP) traffic associated with one or more wireless transmit and/or receive units (WTRUs) via respective bearers used for transporting the IP traffic; and adapt at least one of the bearers based, at least in part, on the user plane congestion information and the rule specified by the PCRF element. - View Dependent Claims (23, 24)

25. A system comprising a policy and charging rules function (PCRF) element and a network element, wherein:
-
the PCRF element is configured to; receive user plane congestion information associated with a radio access network (RAN) from an information collection and reporting element of a core network; obtain subscription information associated with one or more one or more wireless transmit and/or receive units (WTRUs); and specify a rule for enforcing a Quality of Service (QoS) policy; and the network element is configured to; adapt a bearer adapted used for transporting internet protocol (IP) traffic associated with one of the WTRUs based, at least in part, on the user plane congestion information, the subscription information and the rule specified by the PCRF element. - View Dependent Claims (26, 27)
