Abstract
A communication system is described in which a handover procedure is provided to allow a mobile device to transfer from a home base station connected to a core network via a home base station gateway to another base station not coupled via the home base station gateway. A novel extension to the handover procedure is provided in which the home base station gateway is informed of the transfer of the mobile device, allowing context and resources assigned to the mobile device at the base station gateway to be released.
