Abstract: Systems and methods for performing handover coordination between base stations are disclosed. In a first embodiment, a method is disclosed, comprising: receiving, at a base station, a first serving cell signal measurement and a first neighbor cell signal measurement from a particular user equipment (UE); sending an adjustment message, from the base station to the UE, containing a cell-specific offset of the serving cell and a cell-specific offset of the neighbor cell in a reporting threshold based on at least one handover adjustment factor received from a coordinating node; receiving, at the base station and subsequent to adjusting the cell-specific offsets, a second serving cell signal measurement and a second neighbor cell signal measurement; and deciding whether to trigger a handover event based on the first and the second serving cell signal measurement and the first and the second neighbor cell signal measurement and the cell-specific offsets.

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.
