Abstract

A method of controlling an electronic device adapted to interact with a telephone network subscriber identification card includes the following steps:

• • detecting the start of interaction between the card and the device;
  • transferring from the card to the device a program that can be executed by a microprocessor of the device subject to the condition at least of the detection;
  • execution of the transferred program by the microprocessor.

Claims

1. Method of controlling an electronic device adapted to interact with a telephone network subscriber identification card, characterized by the following steps:

detecting a start of interaction between the card and the device;

transferring from the card to the device a program that can be executed by a microprocessor of the electronic device subject to the condition at least of said detection;

execution of the transferred program by the microprocessor.

2. Control method according to claim 1, wherein the transfer step is executed subject to the condition, in addition to said detection, of an indication of the absence of prior execution of the transfer step.

3. Control method according to claim 2, including a step of verifying the additional condition including:

the microcircuit card receiving an identifier of the electronic device;

comparison of the identifier received to an identifier stored in the card and relating to an electronic device to which the transfer step has already been effected.

4. Method according to claim 1, wherein executing the program instigates an exchange of data between the card and the device.

5. Method according to claim 1, wherein executing the program is part of installation of a data processing program in the device.

6. Method according to claim 5, wherein said installation includes connection to a remote server.

7. Method according to claim 6, wherein the connection to a remote server uses the telephone network.

11. Method according to claim 2, wherein executing the program instigates an exchange of data between the card and the device.

12. Method according to claim 3, wherein executing the program instigates an exchange of data between the card and the device.

13. Method according to claim 2, wherein executing the program is part of installation of a data processing program in the device.

14. Method according to claim 3, wherein executing the program is part of installation of a data processing program in the device.

8. Telephone network subscriber identification card including:

means for interacting with an electronic device;

means for sending to the device, on condition at least of initiation of the interaction, a program that can be executed by a microprocessor of the device.

9. Identification card according to claim 8, wherein the sending means are adapted to send the program subject to the condition, in addition to said detection, of an indication of the absence of prior execution of the transfer step.

10. Identification card according to claim 8, wherein the program is adapted to execute a step of installing a data processing program in the device.

15. Identification card according to claim 9, wherein the program is adapted to execute a step of installing a data processing program in the device.
