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.
Claims22
A method comprising:
- receiving an Internet Protocol (IP) flow of packets at an IP mobility anchor point, wherein the IP mobility anchor point is configured to route traffic of a mobile node;
- receiving, at the IP mobility anchor point, signaling to create an extended binding, the extended binding to facilitate routing different subsets of the packets of the IP flow to access networks in simultaneous attachment with the mobile node;
- storing a mapping data structure at the IP mobility anchor point, the mapping data structure to store the extended binding;
- for a duration of time, limiting a number of binding updates for the extended binding based on a threshold;
- and
- routing the different subsets of the packets of the IP flow from the IP mobility anchor point to respective ones of the access networks based on the extended binding.
3 more elements
A method of a first node, comprising:
- communicating, with a second node, an information element relating to an extended binding, the first node is one of a mobile node or an Internet Protocol (IP) mobility anchor point, the second node is the other of the mobile node and the IP mobility anchor point, and the IP mobility anchor point is to route traffic of the mobile node,
- wherein the extended binding defines an association between an IP flow and plural access networks in simultaneous attachment 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 respective ones of the access networks;
- providing an extended binding to a mapping data structure at the IP mobility anchor point, the extended binding to facilitate routing different subsets of the packets of the IP flow to the access networks;
- and
- for a duration of time, limiting a number of binding updates for the extended binding based on a threshold.
2 more elements
An Internet Protocol (IP) mobility anchor point, comprising:
- an interface to receive an IP flow of packets;
- and
- at least one processor configured to:
- receive signaling to create an extended binding, the extended binding to facilitate routing different subsets of the packets of the IP flow to access networks in simultaneous attachment with a mobile node;
- store the extended binding in a mapping data structure at the IP mobility anchor point, the extended binding to map the IP flow to the plural access networks;
- according to the extended binding, route the different subsets of the packets of the IP flow to respective ones of the access networks;
- and
- for a duration of time, limit a number of binding updates for the extended binding based on a threshold.
5 more elements
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 point containing an information element relating to an extended binding, wherein the extended binding defines an association between an IP flow and plural access networks in simultaneous attachment with the mobile node, where the IP flow is associated with the mobile node;
- provide the extended binding to store in a mapping data structure at the IP mobility anchor point, the extended binding to cause the IP mobility anchor point to route different subsets of packets of the IP flow over respective ones of the access networks;
- and
- for a duration of time, limit a number of binding updates for the extended binding based on a threshold.
