Abstract
The invention refers to a method for establishing a radio connection (4, 5) for transmitting and receiving data across one of a plurality of radio interfaces (2, 3) of a mobile radio telecommunication terminal (1). The multiple radio interfaces (2, 3) serve for data transmission and reception across radio connections (4, 5) according to various radio protocols within different sub-radio access networks (9, 10). The coverage of sub-radio access networks (9, 10) is determined and the radio connection (4, 5) is established across at least one of the available sub-radio access networks (9, 10). In order to establish a radio connection (4, 5) for transmitting and receiving data across one of the plurality of radio interfaces (2, 3) of the mobile radio telecommunication terminal (1) more efficiently without waste of energy and waste of bandwidth on the radio connections (4, 5) the necessity for a determination of sub-radio access network (9, 10) coverage is established and coverage of the sub-radio access networks (9, 10) is determined only if determination of sub-radio access network (9, 10) coverage is deemed to be necessary.
