Abstract: A method for topology hiding is disclosed, comprising: receiving, at a gateway, the gateway positioned between a core network and a radio access network, a configuration information request from a base station; analyzing, at the gateway, a topology of the radio access network, the radio access network including the base station; grouping, at the gateway, the base station into a first group based on the topology; sending, from the gateway to the base station, a grouping message to indicate that the base station be placed in the first group; and terminating connections from the core network to one or more base stations in the first group at the gateway as a back-to-back proxy, thereby hiding the topology of the radio access network from the core network.

Abstract: Systems and methods are disclosed for enabling a mesh network node to switch from a base station role to a user equipment role relative to a second mesh network node, and vice versa. By switching roles in this manner, the mesh network node may be able to benefit from increased uplink or downlink speed in the new role. This role reversal technique is particularly useful when using wireless protocols such as LTE that are asymmetric and allow differing throughput on uplink and downlink connections. Methods for determining whether to perform role reversal are disclosed, and methods for using role reversal in mesh networks comprising greater than two nodes are also disclosed.

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.
