Abstract
A mobile node receives access network-specific signaling that is related to an Internet Protocol (IP) flow. The mobile node decides which of multiple access networks to use to send the IP flow based on the access network-specific signaling. The access network-specific signaling may be received from an access network, and the mobile node may interpret the access network-specific signaling as a command to send the IP flow over that access network. The mobile node may update a forwarding policy at the mobile node to indicate that the IP flow should be sent over that access network.
Claims36
An apparatus for facilitating network-based control of a forwarding policy, comprising:
- means for receiving access network-specific signaling that is related to an Internet Protocol (IP) flow;
- and
- means for deciding which of a plurality of physical interfaces within a mobile node that are respectively associated with multiple access networks to use to send the IP flow via an uplink communication link from the mobile node based on the access network-specific signaling when the physical interfaces within the mobile node have no associated IP addresses,
- wherein the access-network specific signaling comprises a bearer modification message that causes a bearer to be modified so that a Traffic Flow Template (TFT) no longer covers the IP flow, and wherein said
- means for deciding which of the plurality of physical interfaces within a mobile node that are respectively associated with the multiple access networks to use comprises means for interpreting the bearer modification message as a command to move the IP flow to another access network.
A mobile node configured to facilitate network-based control of a forwarding policy, comprising:
- receiver circuitry configured to receive access network-specific signaling that is related to an Internet Protocol (IP) flow;
- a memory;
- and
- a processor coupled to the memory and the receiver circuitry, wherein the processor is configured with process-executable instructions to perform operations comprising:
- deciding which of a plurality of physical interfaces within the mobile node that are respectively associated with multiple access networks to use to send the IP flow via an uplink communication link from the mobile node based on the access network-specific signaling when the physical interfaces within the mobile node have no associated IP addresses,
- wherein the access-network specific signaling comprises a bearer modification message that causes a bearer to be modified so that a Traffic Flow Template (TFT) no longer covers the IP flow, and wherein said
- deciding which of the plurality of physical interfaces within a mobile node that are respectively associated with the multiple access networks to use comprises means for interpreting the bearer modification message as a command to move the IP flow to another access network.
A method for facilitating network-based control of a forwarding policy, the method being implemented by a mobile node, the method comprising:
- receiving access network-specific signaling that is related to an Internet Protocol (IP) flow;
- and deciding which of a plurality of physical interfaces within the mobile node that are respectively associated with multiple access networks to use to send the IP flow via an uplink communication link from the mobile node based on the access network-specific signaling when the physical interfaces within the mobile node have no associated IP addresses,
- wherein the access-network specific signaling comprises a bearer modification message that causes a bearer to be modified so that a Traffic Flow Template (TFT) no longer covers the IP flow, and wherein said
- deciding which of the plurality of physical interfaces within a mobile node that are respectively associated with the multiple access networks to use comprises means for interpreting the bearer modification message as a command to move the IP flow to another access network.
A non-transitory computer readable medium having stored thereon processor-executable instructions configured to cause a processor of a computer to perform operations for facilitating network-based control of a forwarding policy, comprising:
- receiving access network-specific signaling that is related to an Internet Protocol (IP) flow;
- and
- deciding which of a plurality of physical interfaces within a mobile node that are respectively associated with multiple access networks to use to send the IP flow via an uplink communication link from the mobile node based on the access network-specific signaling when the physical interfaces within the mobile node have no associated IP addresses,
- wherein the access-network specific signaling comprises a bearer modification message that causes a bearer to be modified so that a Traffic Flow Template (TFT) no longer covers the IP flow, and wherein said
- deciding which of the plurality of physical interfaces within a mobile node that are respectively associated with the multiple access networks to use comprises means for interpreting the bearer modification message as a command to move the IP flow to another access network.
