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.

First claim

What is claimed is:

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.
