Abstract:
A method is disclosed for providing IP access across packet data network gateways (PGWs), comprising: receiving, from a UE, at a coordinating node, an attach request; sending a request to create a first new session to a first PGW; sending a request to create a second new session to a second PGW; receiving, from the first PGW and at the coordinating node, a first request for policies for the UE; receiving, from the second PGW and at the coordinating node, a second request for policies for the UE; opening a first data tunnel from the coordinating node to the first PGW; opening a second data tunnel from the coordinating node to the second PGW without closing the first data tunnel; and opening a data tunnel between the UE and the coordinating node for providing IP access to both the first PGW and the second PGW.
