Abstract

Embodiments of the present disclosure include methods, devices and systems for Bluetooth low energy discovery in wireless application service platforms. One example embodiment relates to transmitting, by a first terminal including a radio, a request message for seeking service, receiving, by a peer terminal, the request message for seeking service, transmitting to the first terminal, by the peer terminal, a response frame advertising service including service provider information.

Claims

1. A wireless device for performing Bluetooth low energy (BLE) discovery, comprising:

a BLE radio,

at least one memory device including computer-executable instructions, and

at least one processor configured to access the computer-executable instructions to perform the operations of;

causing to transmit by the BLE radio a first advertisement frame comprising service information related to one or more services offered or sought by the wireless device; and

identifying a second advertisement frame received by the BLE radio, the second advertisement frame comprising a matched service identification of at least one service offered or sought by the wireless device.

2. The device of claim 1, wherein the first advertisement frame further comprises discovery capability of the wireless device or discovery information of the wireless device.

3. The device of claim 2, wherein the second advertisement frame further comprises a second advertisement identification, discovery capability of a second wireless device sending the second advertisement frame, or discovery information of the second wireless device.

4. The device of claim 3, wherein the at least one processor is further configured to:

perform a Wi-Fi discovery operation based at least in part on the matched service identification.

5. The device of claim 1, wherein the first advertisement frame or the second advertisement frame comprises an advertisement length, a service discovery data advertisement type, organization identification, SDS header or length, or organization specific data.

6. The device of claim 1, wherein a header in the first advertisement frame or the second advertisement frame comprises a Wi-Fi alliance subtype, a seeker or advertiser identification, availability information, or reserved bits.

7. A non-transitory computer-readable medium comprising computer-executable instructions that when executed by a processor cause the operations of:

causing to transmit, by a first device comprising a radio and the processor, a first advertisement frame comprising service information related to one or more services offered or sought by the first device; and

identifying, by the first device, that a second advertisement frame is received, the second advertisement frame comprising a matched service identification of at least one service offered or sought by the first device.

8. The medium of claim 7, wherein the first advertisement frame further comprises discovery capability of the first device or discovery information of the first device.

9. The medium of claim 8, wherein the second advertisement frame further comprises a second advertisement identification, discovery capability of a second device sending the second advertisement frame, or discovery information of the second device.

10. The medium of claim 9, further comprising:

performing, by the first device, a Wi-Fi discovery operation based at least in part on the matched service identification.

11. The medium of claim 7, wherein the first advertisement frame or the second advertisement frame comprises an advertisement length, a service discovery data advertisement type, organization identification, SDS header or length, or organization specific data.

12. The medium of claim 7, wherein a header in the first advertisement frame or the second advertisement frame comprises a Wi-Fi alliance subtype, a seeker or advertiser identification, availability information, or reserved bits.

13. A method for Bluetooth low energy (BLE) discovery, the method comprising:

causing to transmit, by a first device comprising at least one memory device including computer-executable instructions and at least one processor configured to access the computer-executable instructions, a first advertisement frame comprising service information related to one or more services offered by the first device;

identifying, by the first device, that a first scan request frame requesting additional information related to the one or more services offered by the first device is received;

causing to transmit, by the first device, a first scan response frame comprising connectivity capability information of the first device;

identifying, by the first device, that a second advertisement frame comprising a service desired by a second device is received;

causing to transmit, by the first device, a second scan request frame requesting connectivity information from the second device; and

identifying, by the first device, that connectivity information from the second device is received.

14. The method of claim 13, wherein the first scan response frame further comprises device identification of the first device or connectivity information of the first device.

15. The method of claim 13, wherein the second advertisement frame further comprises connectivity capability of the second device or device identification of the second device.

16. The method of claim 13, wherein the first advertisement frame further comprises discovery capability of the first device or discovery information of the first device.

17. The method of claim 13, wherein the second advertisement frame further comprises a second advertisement identification, discovery capability of a second device sending the second advertisement frame, or discovery information of the second device.

18. The method of claim 13, further comprising:

performing, by the first device, a Wi-Fi discovery operation based at least in part on the matched service identification.

19. The method of claim 13, wherein the first advertisement frame or the second advertisement frame comprises an advertisement length, a service discovery data advertisement type, organization identification, SDS header or length, or organization specific data.

20. The method of claim 13, wherein a header in the first advertisement frame or the second advertisement frame comprises a Wi-Fi alliance subtype, a seeker or advertiser identification, availability information, or reserved bits.
