Abstract:
Mobile communication entity providing communication between a mobile terminal and plural mobile communication networks, which communication networks are parts of different mobile communication systems (31, 32, 33, 34, 44), wherein said mobile terminal (42, 43) includes control-channel communication means for receiving data from and for transmitting requests to individual ones of said networks via downlink and uplink control channels, said data including services provided by respective ones of said networks, and wherein said mobile terminal is located relative to said networks for concurrent capability of communication with a plurality of said networks, said mobile terminal having means for indicating a selection of a first connection with a first mobile communication network and a first service offered by the first mobile communication network, the selection being based on a certain criterion or criteria, wherein said mobile terminal (42, 43) is operative to provide a selection of a second mobile communication network and a second service offered by the second mobile communication network, and is operative to maintain open communication channels concurrently with said first and said second mobile communication networks during said selection, said mobile terminal (42, 43) is operative further to establish a second connection with the second mobile communication network when a certain criterion or criteria is met, and the mobile terminal (42, 43) is operative to disconnect said first connection after said second connection has been established; andwherein said mobile terminal comprises at least one data application that directs said mobile terminal to select one of said communication networks and a service offered by a selected one of the communication networks, and wherein an individual one of said communication networks offers at least one of a plurality of services from a set of services including circuit switched data service and a packet switched data service subject to a plurality of parameters from a set of parameters including quality of a transmission channel, capacity of a transmission channel, service availability, data transfer speed, amount of data to be transferred, and service price, said criterion or criteria being based on said parameters.
