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.

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). The one more servers (11) determine and send to each wireless terminal (2) a network selection parameter used by each wireless terminal to select from the first and second cellular communication networks (3, 4) a cellular communication network used to communicate with the one more servers (11), based on one or any combination of an application priority associated with each application, a device priority associated with each wireless terminal (2), and an organization priority associated with an organization to which the plurality of wireless terminals (2) belong. This, for example, allows priority handling regarding a public safety service to be reflected in a selection among a plurality of cellular communication networks.
