Abstract

A method for activating a user interface of a mobile terminal or device having an ISO14443 smart card attached in a ISO7816 reader, where the mobile device monitors the state of the inactive ISO7816 interface, the ISO14443 smart card changes the state of one or more of the ISO7816 contacts when it needs user interaction during contactless communication, and when a state change occurs that did not originate in the mobile device, an interrupt is generated that communicates to the mobile device that smart card requires its services.

Claims

1. A method comprising:

coupling a mobile terminal having a smart card to another device via a contactless connection using the smart card; and

providing an interaction command signal from the smart card to the mobile terminal to initiate interaction and require a service from the mobile terminal related to the contactless connection with the other device, the interaction command signal including a change in the state of one or more contacts between the mobile terminal and the smart card.

2. A method according to claim 1, wherein the smart card provides the interaction command signal during the contactless connection with the other device.

3. A method according to claim 1, wherein the mobile terminal responds to the interaction command signal and generates an interrupt signal to establish the interaction.

4. A method according to claim 1, wherein the mobile terminal activates an interface with the smart card and runs a query to find out what services or information the smart card requires.

5. A method according to claim 1, wherein the mobile terminal monitors the state of the one or more contacts and filters out state changes that happen when the interface between the mobile terminal and the smart card is active.

6. A method according to claim 1, wherein the one or more contacts are a part of a galvanic connection.

7. A method according to claim 1, wherein the method further comprises the step of:

responding to the interaction command signal, for providing an interaction reply signal from the mobile terminal to the smart card with information related to the service.

8. A method according to claim 1, wherein the smart card has an antenna formed as a part thereof, or the smart card is connected to an antenna that forms part of the mobile terminal.

9. A smart card comprising:

one or more modules configured for coupling a mobile terminal to another device via a contactless connection; and

one or more modules configured for providing an interaction command signal to the mobile terminal to initiate interaction and require a service from the mobile terminal related to the contactless connection with the other device, the interaction command signal including a change in the state of one or more contacts between the mobile terminal and the smart card.

10. A smart card according to claim 9, wherein the one or more contacts are a part of a galvanic connection.

11. A smart card according to claim 9, wherein the smart card provides the interaction command signal during the contactless connection with the other device.

12. A smart card according to claim 9, wherein the smart card has an antenna formed as a part thereof, or the smart card is connected to an antenna that forms part of the mobile terminal.

13. A mobile terminal comprising:

one or more modules configured for coupling to another device via a contactless connection using a smart card; and

a media control unit module configured for responding to an interaction command signal from the smart card to initiate interaction and require a service from the mobile terminal related to the contactless connection with the other device, the interaction command signal includes a change in the state of one or more contacts between the mobile terminal and the smart card.

14. A mobile terminal according to claim 13, wherein the one or more contacts are a part of a galvanic connection.

15. A mobile terminal according to claim 13, wherein the smart card provides the interaction command signal during the contactless connection with the other device.

16. A mobile terminal according to claim 13, wherein the media control unit module is configured to respond to the interaction command signal and generates an interrupt signal to establish the interaction.

17. A mobile terminal according to claim 13, wherein the media control unit module is configured to activate an interface with the smart card and runs a query to find out what services or information the smart card requires.

18. A mobile terminal according to claim 13, wherein the media control unit module is configured to monitor the state of the one or more contacts and filters out state changes that happen when the interface between the mobile terminal and the smart card is active.

19. A mobile terminal according to claim 13, wherein either the mobile terminal, the smart card, or both is in an inactive mode.

20. A mobile terminal according to claim 13, wherein either the smart card has an antenna formed as a part thereof, or the smart card is connected to an antenna that forms part of the mobile terminal.

21. A mobile terminal according to claim 13, wherein the media control unit module responds to the interaction command signal, for providing an interaction reply signal from the mobile terminal to the smart card with information related to the service.

22. A method comprising:

coupling a mobile terminal having a smart card to another device via a contactless connection using the smart card, the mobile terminal monitoring the state of one or more contacts and filtering out state changes that happen when an interface between the mobile terminal and the smart card is active; and

providing an interaction command signal from the smart card to the mobile terminal to initiate interaction and require a service from the mobile terminal related to the contactless connection with the other device.

23. A mobile terminal comprising:

one or more modules configured for coupling to another device via a contactless connection using a smart card; and

a media control unit module configured for responding to an interaction command signal from the smart card to initiate interaction and require a service from the mobile terminal related to the contactless connection with the other device, and also configured for monitoring the state of one or more contacts and filtering out state changes that happen when the interface between the mobile terminal and the smart card is active.
