Communication device, communication method, program, and communication system
Provided is a communication device including a contactless communication unit that conducts contactless communication, a wireless communication unit that conducts wireless communication, and a control unit that, in a case in which the contactless communication unit detects another communication device, controls activation start of a first communication mode of the wireless communication unit, and controls a connection process for the wireless communication between the contactless communication unit and the other communication device.
1. A wireless communication device, comprising:
an antenna interface for connecting to an antenna for wireless communication;
a host controller interface for connecting to a host controller, the host controller further connecting to a contactless communication device for contactless communication; and
a control unit configured to discover a wireless communication apparatus through the host controller interface, to start activation of a direct communication mode and to conduct a negotiation about roles during the activation of the direct communication mode, such that the negotiation about roles is performed by contactless communication in parallel with the activation of the direct communication mode by wireless communication.
2. The wireless communication device according to claim 1 , wherein the host controller starts the activation when the wireless communication apparatus is detected with the contactless communication device.
3. The wireless communication device according to claim 2 , wherein the control unit further configured to start sending beacons when the wireless communication device is determined to operate as group owner as a result of the negotiation.
4. A wireless controller device, comprising:
a contactless antenna interface for connecting to a contactless antenna;
a wireless antenna interface for connecting to a wireless antenna;
a control unit configured to discover a wireless communication apparatus through said contactless antenna interface, to start activation of a direct communication mode and to conduct a negotiation about roles during the activation of the direct communication mode, such that the negotiation about roles is performed by contactless communication in parallel with the activation of the direct communication mode by wireless communication.
5. The wireless controller device according to claim 4 , wherein said control unit is further configured to start the activation when the wireless communication apparatus is detected through contactless antenna interface.
6. The wireless controller device according to claim 5 , wherein said control unit is further configured to start sending beacons through the wireless antenna interface when the wireless controller device is determined to operate as group owner as a result of the negotiation.
