Method and system for data transfer
First Claim
1. A method of data transfer between an on board unit including a processor, memory means and interfaces, to an external entity including an integrated circuit card, the method comprising the steps of communicating between a stationary equipment and the on board unit by means of radio signal;
- communicating between the integrated circuit card and the on board unit by radio signal;
knowing by the on board unit a location of storage of at least one predetermined sequence of commands formed as macros stored inside the integrated circuit card;
exchanging the macro over one of interfaces and processing in the on board unit without previously knowing a structuring of data in order to teach the on board unit how to perform respective tasks.

Abstract
A method for data transfer for various applications between a on board unit (OBU), which comprises a processor, memory means and at least one interface to an external entitiy. A sequence of commands is exchanged over the interface and processed by the OBU in order to perform the respective task according to the application of the OBU and/or the external entity. The system for data transfer comprises a macro interpreter in the OBU to receive and interpret the macros from one of its interfaces.

- 7. A system for data transfer by means of radio communication, comprising an on board unit for operations between a stationary equipment and said on board unit, said on board unit including a receiver and transmitter equipment formed as a transponder, a computer with a processor and a memory unit connected to said transponder for receiving signals, processing them and generating signals for retransmission through said transponder by means of a modulation of the signals, said on board unit communicating with at least one external entity, said on board unit including a macro interpreter and being formed so as to read at least one sequence of commands formed as macros and/or parameters from a known location stored inside of the external entity without previously knowing a structure of the macro, said on board unit interpreting the macros and/or storing the parameters in order to perform a respective task according to an application of said on board unit and/or the external entity.
