System and method for providing Internet protocol flow mobility in a network environment
First Claim
1. A method comprising:
- receiving an indication of a radio access technology (RAT) change for a user equipment (UE);
determining availability of a preferred RAT type for a policy related rule associated with the UE, wherein the policy related rule includes, at least in part, the preferred RAT type for one or more service data flows for the UE; and
configuring the one or more service data flows for the UE based, at least in part, on a change in availability of the preferred RAT type following the RAT change wherein based on a determination that the preferred RAT has become unavailable the configuring comprises;
determining whether the one or more service data flows can be moved to a non-preferred RAT type, which is currently available to the UE, based, at least in part, on a session continuity indicator for the one or more service data flows; and
moving the one or more service data flows to the non-preferred RAT type based on the session continuity indicator providing for inter-RAT session continuity.

Abstract
An example method is provided in one example embodiment and may include receiving an indication of a radio access technology (RAT) change for a user equipment (UE); determining availability of a preferred RAT type for a policy related rule associated with the UE, wherein the policy related rule includes, at least in part, the preferred RAT type for one or more service data flows for the UE; and configuring the one or more service data flows for the UE based, at least in part, on a change in availability of the preferred RAT type following the RAT change. In at least one case, the method can include routing downlink packets to the UE using the one or more service data flows for the preferred RAT type if the preferred RAT type is available.

14. An apparatus, comprising:
-
a memory element for storing data; and a processor for executing instructions associated with the data, wherein the executing causes the apparatus to perform operations comprising; receiving an indication of a radio access technology (RAT) change for a user equipment (UE); determining availability of a preferred RAT type for a policy related rule associated with the UE, wherein the policy related rule includes, at least in part, the preferred RAT type for one or more service data flows for the UE; and configuring the one or more service data flows for the UE based, at least in part, on a change in availability of the preferred RAT type following the RAT change wherein based on a determination that the preferred RAT has become unavailable the configuring comprises; determining whether the one or more service data flows can be moved to a non-preferred RAT type, which is currently available to the UE, based, at least in part, on a session continuity indicator for the one or more service data flows; and moving the one or more service data flows to the non-preferred RAT type based on the session continuity indicator providing for inter-RAT session continuity. - View Dependent Claims (15, 16, 17, 18)
