Patent ID: 7787414

Claim:
A method for requesting a network resource for a communication session, comprising: facilitating a communication session between a mobile node and an endpoint; providing a trigger event by a network control platform, the network control platform configured to implement mobility management functions and call access control procedures; receiving the trigger event at a first anchor point, the first anchor point configured to aggregate one or more management services for a plurality of first access routers, the first anchor point operating like a home agent from the viewpoint of an access router, the first anchor point operating like an access router from the viewpoint of the home agent, the plurality of first access routers comprising a first access router used by the mobile node, the trigger event indicating that reservation of a network resource is being requested for the communication session; sending, by the first anchor point, an optimization request requesting performance of an optimization procedure; receiving, at the first anchor point, an optimization response indicating that the optimization request has been granted, the optimization response comprising a care-of address of the endpoint, the care-of address identifying a second anchor point; identifying the second anchor point from the care-of address, the second anchor point configured to aggregate the one or more management services for a plurality of second access routers, the plurality of second access routers comprising a second access router used by the endpoint; establishing, by the first anchor point, a tunnel directly between the first anchor point and the second anchor point using the care-of address; dynamically resizing the tunnel in response to measured traffic sent through the tunnel; and initiating reservation of the network resource for the communication session over the tunnel.
