Abstract
The invention relates to a mobile terminal (20, 30) having a first processing unit (7), a first memory device (21) and SIM card chip (23) including a second memory device (22), the second memory device (22) is reprogrammable. To provide a low price mobile terminal having reduced components and costs and less power consumption the first memory device (21) includes terminal independent data stored in the first memory device (21) before manufacturing of the mobile terminal (20, 30), and individual mobile terminal specific data are stored in the second memory device (22) after manufacturing of the mobile terminal (20, 30).
Claims17
A mobile terminal comprising:
- a first processing unit;
- a first memory device communicatively coupled to the first processing unit and having terminal independent data stored therein, wherein terminal independent data are stored therein during manufacturing of the mobile terminal;
- and
- a SIM card communicatively coupled to the first processing unit and including a second memory device, the second memory device is reprogrammable and has stored therein individual mobile terminal specific data that includes individual mobile terminal calibration values specific to at least one part of the mobile terminal, wherein individual mobile terminal specific data are stored in the second memory device after the mobile terminal is calibrated to be operatively functional and the mobile terminal calibration values are known.
A method for manufacturing a mobile terminal, comprising:
- at least partially assembling a plurality of components that include at least a first processing unit and a first memory device into an individual mobile terminal that is at least partially functionally operative;
- determining at least one individual mobile terminal calibration value for a correction of a respective setting of a respective component of the plurality of components;
- storing terminal independent data that is independent of the at least partially assembled individual mobile terminal in the first memory device;
- storing individual mobile terminal specific data in a second memory device of a first SIM card, the individual mobile terminal specific data including the at least one individual mobile terminal calibration value;
- and
- configuring the mobile terminal device to include the first SIM card such that the mobile terminal device is operable with only the first SIM card and inoperable with another SIM card.
A mobile terminal comprising:
- a first processing unit;
- a first memory device that is one of a read only memory (ROM) or a Flash memory and that has terminal independent data including at least an operation system and start-up sequences stored therein, wherein terminal independent data are stored therein during manufacturing of the mobile terminal, and wherein the first memory device is electrically connected to the first processing unit;
- a SIM card chip that is communicatively coupled to the first processing unit and that includes a second memory device, the second memory device is reprogrammable and has individual mobile terminal specific data stored therein, wherein individual mobile terminal specific data are stored in the second memory device after the mobile terminal is calibrated to be operatively functional;
- and
- at least one high frequency component calibrated specifically for the mobile terminal, and wherein second memory has at least one individual mobile terminal calibration value that sets the at least one high frequency component specifically for the mobile terminal stored therein;
- wherein the first memory has application software, fixed data, and security settings stored therein, and wherein the mobile terminal is fully functionally operable in a post manufacturing state with only the first memory device and the second memory and does not require any other non-volatile memory device to fully operate after manufacturing;
- wherein the mobile terminal includes the first memory device and the second memory device and no other non-volatile memory device.
