Abstract
An apparatus in one example may have: at least two endpoints operatively coupled to one another via an application function (AF) in a home network; a policy decision function operatively coupled to the AF; a policy decision enforcement (PDE) operatively coupled to the one of the endpoints; the PDF operatively coupled to the PDE; and a QoS managed bearer that is operatively connected to the endpoints.
Claims17
An apparatus, comprising:
- at least two endpoints operatively coupled to one another via an application function (AF) in a home network;
- a policy decision function operatively coupled to the AF;
- a policy decision enforcement (PDE) operatively coupled to the one of the endpoints;
- the PDF operatively coupled to the PDE;
- and
- a QoS managed bearer that is operatively connected to the endpoints.

A method, comprising:
- endpoints communicating in a network while negotiating the QoS for an end-to-end multimedia session;
- and
- the network relying on a terminal, operatively coupled to one of the endpoints, to request a bearer that the one endpoint has just negotiated with the other endpoint.
A method, comprising:
- endpoints communicating via an application function in a home network while negotiating the QoS for an end-to-end multimedia session;
- communicating, by the application function, with a policy decision function to provide the negotiated QoS to use as a limit on the QoS requested by a terminal at one of the endpoints for this session;
- authorizing the request, when the terminal makes a request to the policy enforcement function for a QoS managed bearer, based on static subscription policy information using a AAA function;
- performing the authorization;
- checking with the policy decision function to see if it falls within the current policy as determined by the policy decision function based on dynamic application function inputs;
- providing, by the policy decision function, the policy decision to the policy enforcement function;
- responding, by the policy enforcement function, with a success to the terminal;
- and
- creating a bearer for the end-to-end multimedia session.
