Abstract
Embodiments provide for session continuity while a mobile device moves. In some embodiments the UE is served by a serving cluster including a plurality of ANs with redundant links, with each redundant link including a UPGW. This allows a session to be maintained (for example, the UE can maintain the same IP address) as it moves, even though the ANs (and the corresponding UPGWs may change as the UE moves). A session manager (SM) can be utilized to establish a session and configure UPGWs as needed. In some embodiments a branching point can be utilized. In some embodiments the SM configures the branching point.
