A method of providing data to a plurality of devices indicating an operating status of a plurality of network devices, the method comprising determining the operating status of the network devices, and transmitting data to the plurality of devices indicating said operating status of at least some of the network devices. The transmitted data is useable by the plurality of devices to determine whether a connection should be established with a particular one of said plurality of network devices. An embodiment describes a connection control unit (CCU) 2 on a train 1 which connects to base stations A, B en route to provide network connectivity to passengers using mobile computing devices. The CCU maintains a database of the operating status of base stations. Faulty base stations which do not provide Internet connectivity are not selected. The CCU also selects a base station to connect to based on data in generic form allowing different access technologies to be compared. A predicted future availability of a base station is also used to make a selection. |
