Abstract
An IP flow is received by an Internet Protocol (IP) mobility anchor point, where the IP mobility anchor point is to anchor traffic of a mobile node. The IP mobility anchor point routes different subsets of the packets of the IP flow to corresponding different points of attachment of the mobile node.
Claims25
A method comprising:
- receiving, by an Internet Protocol (IP) mobility anchor point, an IP flow of packets, where the IP mobility anchor point is to anchor traffic of a mobile node;
- and
- routing, by the IP mobility anchor point, different subsets of the packets of the IP flow to corresponding different points of attachment of the mobile node.
A method of a first node, comprising:
- communicating, with a second node, an information element relating to an extended binding, where the first node is one of a mobile node and an Internet Protocol (IP) mobility anchor point, where the second node is the other of the mobile node and the IP mobility anchor point, and where the IP mobility anchor point is to anchor traffic of the mobile node,
- wherein the extended binding defines an association between an IP flow and plural points of attachment of the mobile node, and wherein the extended binding is to cause the IP mobility anchor point to route different subsets of packets of the IP flow over corresponding different points of attachment.
An Internet Protocol (IP) mobility anchor point, comprising:
- an interface to receive an IP flow of packets;
- and
- at least one processor configured to:
- in response to the IP flow, access a mapping of the IP flow to plural points of attachment of a mobile node;
- according to the mapping, route different subsets of the packets of the IP flow to corresponding different ones of the points of attachment of the mobile node.

A mobile node comprising:
- an interface to communicate with an Internet Protocol (IP) mobility anchor point;
- and
- at least one processor configured to:
- send signaling to the IP mobility anchor containing an information element relating to an extended binding, wherein the extended binding defines an association between an IP flow and plural points of attachment of the mobile node, where the IP flow is associated with the mobile node, and
- wherein the extended binding is to cause the IP mobility anchor point to route different subsets of packets of the IP flow over corresponding different points of attachment.
