MOBILE IP MULTIPLE REGISTRATIONS AND PCC INTERACTIONS
First Claim
1. A method for provisioning policy rules for multiple data packet sessions over a wireless communication network to user equipment, comprising:
- establishing a first Internet Protocol (IP) session for user equipment (UE) for wireless data packet communications by obtaining an IP address provided by an access policy enforcement function at an access node;
instantiating a second IP session for UE for the wireless data packet communications by binding the IP address of the first session with a home address (HoA) provided by a core policy enforcement function remote to the access node;
communicating the establishment of the first and second IP sessions to a policy rule function;
communicating an associated IP address of the first session in response to instantiation of the second IP session to the policy rule function; and
tying the first and the second sessions to identify the policy enforcement function where the policy rules need to be enforced.

Abstract
In a wireless communication system having multiple access nodes, a home agent (HA) maintains home address (HoA) for a mobile node so that an IP session can be established. As the mobile node moves within a coverage area of various access nodes, the mobile node can establish a secure relationship with a local access gateway and thereby register a local IP address, referred to as a care-of-address (CoA), with the HA. Mobile IP protocol can be established so that multiple sessions can be conducted. In maintaining policy and charging control (PCC), HA informs a policy and charging rules function (PCRF), which in turn can then send the appropriate PCC rules (e.g., IP flows and related policies) to a policy and charging enforcement function (PCEF) for a particular access gateway. Coordination necessary to associate CoA and HoA can further include filter information as to application can run on a particular interface.
