Abstract:
1. A mobile radio telecommunication terminal comprising: a plurality of radio interfaces dedicated for transmitting and receiving data across radio connections according to various radio protocols; means for detecting sub-radio access networks dedicated for transmitting and receiving data according to the various radio protocols; means for connecting to at least one of the available sub-radio access networks and thereby establishing at least one radio connection; means for determining whether a process of detecting sub-radio access networks and connecting to the at least one available sub-radio access network is necessary; and means for selecting a radio connection of those available to be used for transmitting and receiving data, wherein the means for detecting sub-radio access networks are activated only if the process of detecting and possibly connecting to the at least one sub-radio access network is determined to be necessary, wherein a criterion to trigger detecting sub-radio access networks, or connecting to the at least one available or selected sub-radio access network consists of bandwidth, quality level, security level and mobility features, wherein the means for selecting a radio connection comprises means for selecting one of the radio interfaces for transmitting and receiving data across the radio connection of a certain sub-radio access network available, in case more than one sub-radio access network is available, and wherein the means for selecting one of the radio interfaces when setting up a new radio service across a radio connection first by default select the radio interface with the lowest bandwidth available on the radio connection assigned to the radio interface.
