Abstract: A communication system is disclosed comprising a gateway connecting a source base station and a target base station. The gateway receives a message from the source base station initiating a handover of a mobile device from the source to the target base station. The received message comprises a security context (an NCC-KeNB pair and/or a KeNB*) for securing communications with the mobile device, and for deriving a further key for securing subsequent communications with the mobile device. The gateway generates and sends, to the target base station, a message requesting the target base station to carry out a handover, the message comprising the security context.

Abstract: A gateway is described which facilitates a change of communication cell for a mobile device in a communication system, which includes a core network. The gateway receives messages from a base station operating a cell and forwards the messages received from the base station to the core network. The gateway intercepts a message relating to a change of communication cell, from a source cell in which the mobile communication device is located to a target cell, to determine if the core network needs to be notified of the change of cell. When it is determined that the core network needs to be notified, the gateway generates a message for providing information relating to the change of cell to the core network and transmits the message to the core network.
