    Abstract: Systems and methods for handovers with simplified network topology are disclosed. In a first embodiment, a method is disclosed, comprising: at a coordinating gateway during a handover of a mobile device from a first base station to a second base station, receiving a first handover request from the first base station; discarding a first shared security key received in the first handover request; sending a tunnel switching request to a core network node; obtaining precursors for a second shared security key from the core network node in a response to the switching request; sending a second handover request to the second base station with the precursors to calculate the second shared security key for securing a data connection for the mobile device following the handover; deriving the second shared security key from the obtained precursors at the first base station; and deriving the second shared security key from the obtained precursors at the coordinating gateway.

    Abstract: A gateway for X2 interface communication is provided, including: an X2 internal interface for communicating with, and coupled to, a plurality of radio access networks (RANs); and an X2 external interface for communicating with, and coupled to, a destination outside of the plurality of RANs, the X2 external interface further including a single X2 endpoint for the plurality of radio access networks, such that the X2 external interface provides a single interface for an external macro cell or core network to interact with the plurality of radio access networks. The gateway may further include a handover module for maintaining X2 signaling associations and transactions for incoming and outbound handovers, including X2 to S1 and S1 to X2 translation.

    Abstract: A method for providing stateful proxying is disclosed, comprising: associating a first base station with a first base station identifier at a signaling protocol gateway, and with a first Internet Protocol (IP) address of the signaling protocol gateway; associating a second base station with a second base station identifier at the signaling protocol gateway, and with a second IP address of the signaling protocol gateway; establishing a first signaling protocol connection between a third base station and the first base station via the signaling protocol gateway with the first base station using the first IP address of the signaling protocol gateway; and establishing a signaling protocol connection between the third base station and the second base station with the second base station using the second IP address of the signaling protocol gateway.
