Abstract
A communication entity (such as a User Equipment (UE), an Access Gateway (AGW), a Packet Data Network Gateway (PGW), a Policy Charging Rule Function (PCRF), and so forth) notifies another communication entity that the UE intends to use a single Internet Protocol (IP) address for connections to multiple AGWs. The communication entity also sends information that is related to at least one of the UE's IP flows to another communication entity.
Claims50
A communication entity in a Proxy Mobile IP communication environment, comprising:
- means for notifying another communication entity that a wireless device intends to use a single Internet Protocol (IP) address for connections to multiple access gateways, wherein the wireless device has a plurality of IP sessions connected through a first access gateway;
- means for sending information that is related to at least one of the wireless device's IP flows to the other communication entity, wherein at least one of the plurality of IP sessions is moved to a connection with a second access gateway while at least one other of the plurality of IP sessions remains connected through the first access gateway:
- and
- means for performing a quality of service (QoS) negotiation between the wireless device and the second access gateway, wherein the means for performing a QoS negotiation comprises:
- means for mapping QoS rules and a corresponding traffic flow template to the connection between the wireless device and the second access gateway;
- and
- means for providing information instructing the wireless device to move data packets of the at least one of the plurality of IP sessions to the connection with the second access gateway while maintaining data packets of the at least one other of the plurality of IP sessions through the first access gateway.

A communication entity in a Proxy Mobile IP communication environment, comprising:
- circuitry configured to:
- notify another communication entity that a wireless device intends to use a single Internet Protocol (IP) address for connections to multiple access gateways, wherein the wireless device has a plurality of IP sessions connected through a first access gateway;
- send information that is related to at least one of the wireless device's IP flows to the other communication entity, wherein at least one of the plurality of IP sessions is moved to a connection with a second access gateway while at least one other of the plurality of IP sessions remains connected through the first access gateway;
- and
- perform a quality of service (QoS) negotiation between the wireless device and the second access gateway, wherein the QoS negotiation comprises:
- mapping QoS rules and a corresponding traffic flow template to the connection between the wireless device and the second access gateway, and
- providing information instructing the wireless device to move data packets of the at least one of the plurality of IP sessions to the connection with the second access gateway while maintaining data packets of the at least one other of the plurality of IP sessions through the first access gateway.

A method for IP flow mobility, the method being implemented by a communication entity in a multi-interface communication environment using Proxy Mobile IP, the method comprising:
- notifying another communication entity that a wireless device intends to use a single Internet Protocol (IP) address for connections to multiple access gateways, wherein the wireless device has a plurality of IP sessions connected through a first access gateway;
- sending information that is related to at least one of the wireless device's IP flows to the other communication entity, wherein at least one of the plurality of IP sessions is moved to a connection with a second access gateway while at least one other of the plurality of IP sessions remains connected through the first access gate;
- and
- performing a quality of service (QoS) negotiation between the wireless device and the second access gateway, wherein the QoS negotiation comprises:
- mapping QoS rules and a corresponding traffic flow template to the connection between the wireless device and the second access gateway, and
- providing information instructing the wireless device to move data packets of the at least one of the plurality of IP sessions to the connection with the second access gateway while maintaining data packets of the at least one other of the plurality of IP sessions through the first access gateway.

A non-transitory computer-readable storage medium having stored thereon processor-executable instructions configured to cause a processor of a communication entity in a Proxy Mobile IP communication environment to perform operations comprising:
- notifying another communication entity that a wireless device intends to use a single Internet Protocol (IP) address for connections to multiple access gateways, wherein the wireless device has a plurality of IP sessions connected through a first access gateway;
- sending information that is related to at least one of the wireless device's IP flows to the other communication entity, wherein at least one of the plurality of IP sessions is moved to a connection with a second access gateway while at least one other of the plurality of IP sessions remains connected through the first access gateway,
- performing a quality of service (QoS) negotiation between the wireless device and the second access gateway, wherein the QoS negotiation comprises:
- mapping QoS rules and a corresponding traffic flow template to the connection between the wireless device and the second access gateway, and
- providing information instructing the wireless device to move data packets of the at least one of the plurality of IP sessions to the connection with the second access gateway while maintaining data packets of the at least one other of the plurality of IP sessions through the first access gateway.
