Abstract

A method is provided for generating a broadcast packet at a first device including an address; transmitting the generated broadcast packet to a second device through a first protocol. The first device may communicate with the second device via the transmitted address through a second protocol different from the first protocol. Alternatively, an apparatus is provided to receive an unsolicited broadcast packet including an address through a wireless, close-by communication protocol; extract from the broadcast packet identification information about the remote device; and store the extracted identification information in association with the remote device. Alternatively, a computer-readable medium is provided storing instructions to receive a an unsolicited broadcast packet including an address through a first protocol; extract from the broadcast packet identification information, including the address and a service available at the remote device; and communicate with the remote device via a second protocol.

Claims

1. A method, comprising:

generating a broadcast packet at a first device including an address of the first device;

transmitting the generated broadcast packet through a first protocol, the first protocol being a wireless, close-by communication protocol;

wherein the transmission of the generated broadcast packet is not solicited by a second device; and

wherein the first device may communicate with the second device via the address communicated in the broadcast packet through a second protocol different from the first protocol.

2. The method of claim 1, further comprising:

receiving a communication from the second device through the second protocol via a third protocol.

3. The method of claim 1, wherein the broadcast packet includes

identification information of the first device and services available at the first device.

4. The method of claim 1, further comprising:

retransmitting the generated broadcast packet at periodic intervals.

5. The method of claim 1, wherein generating a broadcast packet includes:

selecting identification information to include in the broadcast packet from a plurality of identification information.

6. The method of claim 5, wherein the identification information includes a service provided by the first device.

7. The method of claim 1, further comprising:

encrypting the generated broadcast packet.

8. The method of claim 3, further comprising:

receiving an indication of the identification information to include the broadcast packet from an interface presented on a display.

9. An apparatus, comprising:

a receiver to receive an unsolicited broadcast packet from a remote device through a wireless, close-by communication protocol, the unsolicited broadcast packet including an address;

an extraction module to extract from the broadcast packet identification information about the remote device, including the address of the remote device; and

storage to store the extracted identification information in association with the remote device.

10. The apparatus of claim 9, further comprising:

a decryption module to decrypt the received unsolicited broadcast packet with a pre-shared key.

11. The apparatus of claim 9, wherein the storage is further to associate the remote device with a service associated with the identification information included in the broadcast packet.

12. The apparatus of claim 11, wherein the apparatus is a mobile computing device.

13. The apparatus of claim 9, wherein:

the receiver is to receive the unsolicited broadcast packet from the remote device periodically, the broadcast packet including the identification information of the remote device;

the extraction module is to extract the identification information of the remote device from the broadcast packet; and

the storage is to update a date and time each time the unsolicited broadcast packet is received from the remote device.

14. The apparatus of claim 13, wherein the remote device, the address of the remote device, the extracted information associated with remote device, and the time and date the unsolicited broadcast packet is received is stored in a close-by-device list in storage.

15. The apparatus of claim 9, wherein the receiver receives the broadcast packet from a remote device through a proxy device.

16. The apparatus of claim 11, further comprising:

a display device to display an indication that the service of the remote device is available at the apparatus.

17. A non-transitory computer-readable medium, storing a set of instructions, executable by a processor, to perform a method to:

receive an unsolicited broadcast packet from a remote device through a first protocol, the first protocol being a wireless, close-by communication protocol, the unsolicited broadcast packet including an address and a service available at the remote device;

extract from the broadcast packet identification information about the remote device, including the address of the remote device and the service available at the remote device;

store the extracted identification information in association with the remote device; and

communicate with the remote device via the address extracted from the unsolicited broadcast communication packet via a second protocol.

18. The non-transitory computer-readable medium of claim 17, the method further to:

receive the unsolicited broadcast packet from the remote device periodically;

extract the identification information of the remote device from the broadcast packet; and

update a date and time each time the unsolicited broadcast packet is received from the remote device.

19. The non-transitory computer-readable medium of claim 18, the method further to:

remove the remote device from storage when an unsolicited broadcast packet has not been received from the remote device within a predetermined period of time.

20. The non-transitory computer-readable medium of claim 17, the method further to:

decrypt the received unsolicited broadcast packet with a pre-shared key.
