Abstract
A mobile station for transmitting a mobile radio signal to a base station has a memory device in which a number of available applications 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 for the transmission connection. Based upon the calculations, the most cost-efficient application for the desired transmission is selected. The actual transmission of the communication data for the base station is then carried out on the basis of this application.
Claims12
A mobile station for transmitting communication data to a base station in accordance with at least one communication standard comprising:
- memory means for storing charge data which correspond to at least two different applications, each application authorizing a user of the mobile station to transmit the communication data in accordance with the communication standard corresponding to the application with the aid of the mobile station;
- a selection device for selecting a most cost-efficient application for a certain transmission connection depending on the charge data provided for each application and on the basis of a predetermined transmission duration to be expected, and
- at least one transmitting and receiving unit for transmitting the communication data in accordance with the most cost-efficient application selected by the selection device
- such that, after a destination code corresponding to the certain transmission connection has been entered and the most cost-effective application for the certain transmission connection has been selected, the entered destination code is correctable depending on the selected application when the selected application relates to a private branch exchange, in order to be able to carry out the transmission from the private branch exchange to the external base station.
A method of selecting among a plurality of applications available to a mobile phone for establishing connectivity for outgoing calls comprising the steps of:
- storing charge data in memory at said mobile phone such that said memory includes charge information for each of said applications;
- receiving input of first call information at said mobile phone, said first call information being indicative of a first outgoing call to a destination phone;
- accessing said charge data within said memory to determine costs relevant to utilizing said applications to establish connectivity for said first outgoing call;
- selecting one of said applications based upon cost-efficiency in conducting said first outgoing call;
- correcting, if necessary, the first call information in order to be able to carry out the transmission from a private branch exchange;
- initiating said first outgoing call to said destination phone via said selected application.
