Abstract: One or more servers (11) communicate with one or more applications running on each of a plurality of wireless terminals (2) via a first or second cellular communication network (3, 4). Depending on a load of the first cellular communication network, the one more servers (11) select from the first and second cellular communication networks (3, 4) a cellular communication network to be used by each wireless terminal (2) to communicate with the one more servers (11). The one more servers (11) send to each wireless terminal (2) a control message to prompt each wireless terminal (2) to use the selected network. This for example makes it possible to select among a plurality of cellular communication networks in consideration of load status of the cellular communication networks.
