Abstract: A cellular radio network system and method for communicating with at least one vehicle-based mobile gateway terminal is provided. The at least one mobile gateway terminal is configured to communicate a network service for one or more user mobile terminals on-board the vehicle. A plurality of network cells provide cellular radio network coverage along a route of the vehicle. Each network cell is dedicated for communication with the at least one vehicle-based mobile gateway terminal so as to allow communication between the at least one vehicle-based mobile gateway terminal and a core network of the cellular radio network.
