Abstract

The communication control device includes a dedicated contact surface, a control unit and a wireless communication unit. Upon contact between a dedicated contact surface of one communication control device and a dedicated contact surface of another communication control device, the two control units initiate establishing a secure communication session. This initiation includes negotiating initiator and acceptor roles for the communication control devices and exchanging authentication information to enable a wireless secure communication session between the communication control devices.

Claims

1. A method for at least partially initiating a communication session between a first communication device and a second communication device, wherein the first and the second devices have a dedicated contact surface, the method comprising:

initiating a communication session between the communication devices, wherein initiating a communication session includes;

detecting that the dedicated contact surface of the first communication device and the dedicated contact surface of the second communication device are in physical contact with each other to enable wireless communication between the first and second communication devices.

2. A method according to claim 1, wherein the initiating a communication session is performed over the contact interface between the dedicated contact surface of the first communication device and the dedicated contact surface of the second communication device.

3. A method according to claim 1, wherein the initiating a communication session is performed over the contact interface between the dedicated contact surface of the first communication device and the dedicated contact surface of the second communication device, the method further comprising:

negotiating between the two communication devices to determine which one of the devices will take an initiator role.

4. A method according to claim 3, wherein the negotiating includes determining which one of the devices will take an acceptor role.

5. A method according to claim 4, wherein the initiating a communication session comprises:

exchanging authentication information between the first and second communication devices, wherein one of the first and second devices has the initiator role and the other of the first and second devices has an acceptor role.

6. A method according to claim 1, further comprising:

continuing the communication session over a wireless interface between the first and second communication devices.

7. A communication device for initiating a secure communication session between a communication control device and another communication control device, the communication control device comprising:

a dedicated contact surface configured to physically contact a dedicated contact surface of the other communication control device; and

a control unit connected to the dedicated contact surface of the communication control device and configured to initiate communication by detecting physical contact between the dedicated contact surface of the communication control device and the dedicated contact surface of the other communication control,

wherein the communication control device is configured to connect to a wireless communication unit to enable wireless communication over a wireless interface between the wireless communication unit associated with the communication control device and a wireless communication unit associated with the other communication control device.

8. A communication control device according to claim 7, wherein the dedicated contact surface and the wireless communication unit are connected to the control unit.

9. A communication control device according to claim 7 wherein the control unit is configured to initiate communication over the contact interface between the dedicated contact surface of the communication control device and the dedicated contact surface of the other communication control device.

10. A communication control device according to claim 7, wherein at least part of the dedicated contact surface of the communication control device is configured to conduct electric current.

11. A portable communication device configured to communicate with at least one other portable communication device, wherein the portable communication device comprises a comunication control unit that initiates a secure communication session between the communication control device and a communication control device of the other portable communication device the communication control device of the portable communication device comprising:

a dedicated contact surface configured to physically contact a dedicated contact surface of the other communication control device,

a control unit connected to the dedicated contact surface, of the communication control device and configured to detect physical contact over the contact interface between the dedicated contact surface of the communication control device and the dedicated contact surface of the other communication control device, wherein the communication control device is configured to couple to a wireless communication unit to enable wireless communication over the wireless interface between the wireless communication unit of the communication control device and a wireless communication unit associated with the other communication control device.

12. A portable communication device according to claim 11, wherein the dedicated contact surface and the wireless communication unit of the portable communication device are connected to the control unit.

13. A portable communication device, according to claim 11, wherein the wireless communication unit is a Bluetooth™

unit.

14. A portable communication device, according to claim 11, wherein the portable communication device is a mobile telephone.

15. A portable communication device, according to claim 11, wherein at least part of the dedicated contact surface of the portable communication device protrudes from an exterior surface of the portable communication device, and is configured to enable physical contact between the dedicated contact surface of the portable communication device and a dedicated contact surface of the other portable communication device.

16. A portable communication device, according to claim 11, wherein at least part of the dedicated contact surface of the portable communication device is configured to protrude from an exterior surface of the portable communication device, and is configured to enable physical contact over the contact interface between the dedicated contact surface of the portable communication device and a dedicated contact surface of the other portable communication device.

17. A portable communication device, according to claim 11, wherein at least part of the dedicated contact surface of the portable communication device has a convex shape from an exterior surface, which is configured to enable physical contact over the contact interface between the dedicated contact surface of the portable communication device and a dedicated contact surface of the other portable communication device.
