1. A method of steering traffic associated with multi-homed user equipment (UE), the method comprising:
- receiving, at a gateway device configured to communicate with a multi-homed UE via any of a plurality of paths, policy information including path selection rules; and
selecting, at said gateway device and using said path selection rules, one of said plurality of paths for communicating with said multi-homed UE via an IP address common to each of said plurality of paths, each of said plurality of paths being associated with a respective access network;
wherein said path selection rules configure said gateway device to select the same one of said plurality of paths as selected by said UE.

Abstract
Methods apparatus and systems providing a mechanism for policy-based steering of user flows/applications via paths traversing different access networks between multi-homing user equipment (UE) and a gateway device in a manner avoiding UE signaling, wherein the UE address is the same for each path, and wherein the same flow/application paths are selected by both the UE and the gateway device in accordance with-based criteria.

15. A method of steering traffic associated with multi-homed UE, the method comprising:
-
propagating, from a network manager, policy information including path selection rules for configuring a gateway device and each of a plurality of multi-homed UEs serviced by the gateway device; said path selection rules configuring each UE serviced by the gateway device to select a respective one of a plurality of paths between the UE and the gateway device; said path selection rules configuring the gateway device to select, for each UE serviced by the gateway device, the same one of the plurality of paths selected by the UE; each multi-homed UE being associated with a single IP address for communicating via any selected path between the UE and the gateway device, each of the plurality of respective paths being associated with the respective access network. - View Dependent Claims (16)

17. An apparatus including a processor and memory, where the processor is configured to perform of steering traffic associated with multi-homed user equipment (UE), the method comprising:
-
receiving, at a gateway device configured to communicate with a multi-homed UE via any of a plurality of paths, policy information including path selection rules; and selecting, at said gateway device and using said path selection rules, one of said plurality of paths for communicating with said multi-homed UE via an IP address common to each of said plurality of paths, each of said plurality of paths being associated with a respective access network; wherein said path selection rules configure said gateway device to select the same one of said plurality of paths as selected by said UE.
