MOBILE STATION HAVING A COST-EFFICIENT CALL MANAGEMENT METHOD AND SYSTEM

摘要

A mobile station (1) for transmitting a mobile radio signal to a base station has a memory device (8) in which a number of available applications (18) are stored which can relate to different "carriers", i.e., mobile radio network systems or service providers within a single mobile radio network. A selection device of the mobile station calculates expected charges for a desired connection for each of these applications which are being considered (17) for the transmission connection. Based upon the calculations, the most cost-efficient application for the desired transmission is selected (4). The actual transmission (11, 12 and 13) of the communication data for the base station is then carried out on the basis of this application.
