Abstract

A near field communication device (100) for providing a communication path between a processing unit of the device and an external device, wherein the device (100) comprises the processing unit (102) and a control unit (101) coupled to the processing unit, wherein the control unit (101) is adapted for establishing a communication between the control unit and the external device (104) for providing a communication path between the processing unit and the external device via the control unit serving as a gateway.

Claims

1. A near field communication device for providing a communication path between a processing unit of the device and an external device, the device comprising

the processing unit;

a control unit coupled to the processing unit;

wherein the control unit is adapted for establishing a communication between the control unit and the external device for providing a communication path between the processing unit and the external device via the control unit serving as a gateway,

wherein the control unit is adapted for switching for communicating with a plurality of external devices.

2. The device according to claim 1, wherein the control unit is adapted for controlling synchronization of communicating with the plurality of external devices.

3. The device according to claim 1, wherein the processing unit is a secure element.

4. The device according to claim 1, wherein the processing unit is selected form the group consisting of a universal integrated circuit card and a subscriber identity module card.

5. The device according to claim 1, wherein the control unit is adapted for using a single wire protocol for establishing the communication to the processing unit.

6. The device according to claim 1, wherein the processing unit is free of a direct communicative coupling with the external device.

7. The device according to claim 1, wherein the device is a mobile device.

8. The device according to claim 1, realised as at least one of the group consisting of a mobile phone, a hearing aid, a dictating machine, a conference call device, a portable audio player, a portable video player, a head mounted display, a medical communication system, a body-worn device, a DVD player, a CD player, a harddisk-based media player, an internet radio device, a public entertainment device, and an MP3 player.

9. A communication system comprising a device of claim 1 and an external device.

10. The communication system according to claim 9, wherein the external device is a mobile host.

11. Method of providing a communication path between a processing unit of a near field communication device and an external device, the method comprising

establishing a communication between a control unit of the near field communication device and the external device, and

providing a communication path between the processing unit and the external device via the control unit serving as a gateway,

switching by the control unit for communicating with a plurality of external devices.

12. A non-transitory computer-readable medium, in

which a computer program of providing a communication path between a processing unit and an external device is stored, which computer program, when being executed by a processor, is adapted to carry out or control a method according to claim 11.

13. A program element of providing a communication path between a processing unit and an external device, which program element, when being executed by a processor, is adapted to carry out or control a method according to claim 11.
