Abstract

Methods, systems, and devices are described for establishing an infrared (IR) triggered radio communication connection between two devices. Upon aligning IR ports, IR trigger messages can be exchanged between devices and/or access points using an IR communication link, where the IR trigger messages indicate intent and capability of establishing the connection. The IR trigger messages may trigger device discovery and connection using the radio communication technology. Additional operations (e.g., exchanging files, streaming content, etc.) may be performed automatically between the devices upon establishing the connection. The radio communication technology may include wireless local area network (WLAN), Wi-Fi, Wi-Fi P2P, Wi-Fi-Direct, or other similar radio link between two devices, such as between a mobile device and another mobile device, a printer, a display, an Access Point, and the like.

Claims

1. A method, comprising:

transmitting a first infrared (IR) trigger message from a first device to a second device using an IR communication link, the first IR trigger message indicating an intent to establish a connection using a radio communication technology;

receiving, via the IR communication link, a second IR trigger message; and

in response to receiving the second IR trigger message, establishing the connection with the second device using the radio communication technology.

2. The method of claim 1, further comprising:

determining that an IR signal strength of the IR communication link is above a threshold signal strength based on the received second IR trigger message; and

determining that the second IR trigger message indicates the intent and a capability to establish the connection using the radio communication technology.

3. The method of claim 1, wherein establishing the connection comprises:

transmitting, by the first device, a scan request using the radio communication technology; and

receiving, by the first device, a scan response from the second device using the radio communication technology.

4. The method of claim 1, wherein establishing the connection further comprises:

determining a P2P initiator device by comparing a MAC address of the first device and a MAC address of the second device; and

transmitting, if the first device is the P2P initiator device, a provisional discovery (PD) request to initialize a P2P group with the second device.

5. The method of claim 4, further comprising:

exchanging the MAC addresses of the first device and the second device for determining the P2P initiator device via the IR communication link.

6. The method of claim 1, wherein establishing the connection with the second device further comprises exchanging connection information associated with the radio communication technology with the second device over the IR communication link, wherein the connection information comprises one or more of a P2P IE intent value, a listening channel ID, or an operating channel ID.

7. The method of claim 1, wherein establishing the connection comprises transmitting connection information to a third device to allow the third device to establish the connection with the second device using the radio communication technology.

8. The method of claim 1, wherein the radio communication technology comprises one from a group consisting of Wi-Fi and Wi-Fi-Direct.

9. The method of claim 1, wherein the connection is a peer to peer (P2P) connection.

10. The method of claim 1, wherein one of the first device and the second device is one from a group consisting of a mobile device, a printer, a projector, an display, a photo frame, and a set-top box.

11. The method claim 10, wherein the other of the first device or the second device is a mobile device.

12. A computer program product comprising a non-transitory computer-readable medium storing instructions executable by a processor to:

transmit a first infrared (IR) trigger message to a second device using an IR communication link, the first IR trigger message indicating an intent to establish a connection using a radio communication technology;

receive, via the IR communication link, a second IR trigger message; and

in response to receiving the second IR trigger message, establish the connection with the second device using the radio communication technology.

13. The computer program product of claim 12, wherein the instructions are executable by the processor to:

determine that an IR signal strength of the IR communication link is above a threshold signal strength based on the received second IR trigger message; and

determine that the second IR trigger message indicates the intent and a capability to establish the connection using the radio communication technology.

14. The computer program product of claim 12, wherein the instructions executable by the processor to establish the connection further comprise instructions to:

transmit a scan request using the radio communication technology; and

receive a scan response from the second device using the radio communication technology.

15. The computer program product of claim 12, wherein the instructions executable by the processor to establish the connection further comprise instructions to:

determine a P2P initiator device by comparing a MAC address of the wireless communications device and a MAC address of the second device; and

transmit, if the wireless communications device is the P2P initiator device, a provisional discovery (PD) request to initialize a P2P group with the second device.

16. A wireless communications device, comprising:

an infrared (IR) communication port to;

transmit a first infrared (IR) trigger message to a second device over an IR communication link, the first IR trigger message indicating an intent to establish a connection using a radio interface of the wireless communications device, and

receive, via the IR communication link, a second IR trigger message; and

a radio interface communicably coupled to the IR communication port and to, in response to the IR communication port receiving the second IR trigger message, establish the connection with the second device.

17. The wireless communications device of claim 16, the IR communication port to:

determine that an IR signal strength of the IR communication link is above a threshold signal strength based on the received second IR trigger message; and

determine that the second IR trigger message indicates the intent and a capability to establish the connection using the radio communication technology.

18. The wireless communications device of claim 16, the radio interface to:

transmit a scan request using the radio communication technology; and

receive a scan response from the second device using the radio communication technology.

19. The wireless communications device of claim 16, the IR communication port to transmit and receive connection information associated with the radio communication technology with the second device over the IR communication link, wherein the connection information comprises one or more of a P2P IE intent value, a listening channel ID, or an operating channel ID.

20. The wireless communications device of claim 16, the radio interface to transmit connection information to a third device to allow the third device to establish the connection with the second device using the radio communication technology.
