Abstract

A method of integrating Bluetooth protocols in establishing a connection between a Bluetooth-enabled mobile device and a vehicle telematics system having two or more Bluetooth controllers includes establishing a Bluetooth communication channel between the mobile device and a first Bluetooth controller. The first Bluetooth controller authenticates the mobile device. In response to successful authentication of the mobile device, a secure connection between the first Bluetooth controller and a second Bluetooth controller is established. Authentication credentials of the authenticated mobile device are sent from the first Bluetooth controller to the second Bluetooth controller. Commands received from the mobile device via the Bluetooth communication channel are processed by the first Bluetooth controller or the second Bluetooth controller depending on the protocol utilized by the mobile device.

First claim

What is claimed is:

1 . A method of integrating Bluetooth protocols in establishing a connection between a Bluetooth-enabled mobile device and a vehicle telematics system having two or more Bluetooth controllers, the method comprising steps of:
establishing a Bluetooth communication channel between a mobile device and a first Bluetooth controller; authenticating the mobile device by the first Bluetooth controller; establishing a secure connection between the first Bluetooth controller and a second Bluetooth controller, in response to successful authentication of the mobile device; sending authentication credentials of the authenticated mobile device from the first Bluetooth controller to the second Bluetooth controller; and processing commands received from the mobile device via the Bluetooth communication channel by the first Bluetooth controller or the second Bluetooth controller.

2 . The method according to claim 1 , wherein the first Bluetooth controller comprises a Bluetooth low energy controller and wherein the second Bluetooth controller comprises a Bluetooth classic controller.

3 . The method according to claim 1 , wherein the Bluetooth communication channel comprises a two-way communication channel.

4 . The method according to claim 1 , wherein the secure connection provides encrypted communication between the first Bluetooth controller and the second Bluetooth controller.

5 . The method according to claim 1 , wherein establishing a Bluetooth communication channel between a mobile device and a first Bluetooth controller comprises receiving advertisement data from the mobile device.

6 . The method according to claim 5 , wherein the advertisement data includes mobile device's address information.

7 . The method according to claim 4 , wherein the encrypted communication comprises an encrypted authentication signal.

8 . The method according to claim 1 , wherein establishing a Bluetooth communication channel comprises determining a received signal strength indicator (RSSI) value based on a signal received from the mobile device.

9 . A computer program product for integrating Bluetooth protocols in establishing a connection between a Bluetooth-enabled mobile device and a vehicle telematics system having two or more Bluetooth controllers, the computer program product comprising:
one or more computer-readable storage devices and a plurality of program instructions stored on at least one of the one or more computer-readable storage devices, the plurality of program instructions comprising: program instructions to establish a Bluetooth communication channel between a mobile device and a first Bluetooth controller; program instructions to authenticate the mobile device by the first Bluetooth controller; program instructions to establish a secure connection between the first Bluetooth controller and a second Bluetooth controller, in response to successful authentication of the mobile device; program instructions to send authentication credentials of the authenticated mobile device from the first Bluetooth controller to the second Bluetooth controller; and program instructions to process commands received from the mobile device via the Bluetooth communication channel.

10 . The computer program product of claim 9 , wherein the first Bluetooth controller comprises a Bluetooth low energy controller and wherein the second Bluetooth controller comprises a Bluetooth classic controller.

11 . The computer program product of claim 9 , wherein the Bluetooth communication channel comprises a two-way communication channel.

12 . The computer program product of claim 9 , wherein the secure connection provides encrypted communication between the first Bluetooth controller and the second Bluetooth controller.

13 . The computer program product of claim 9 , wherein the program instructions to establish a Bluetooth communication channel between a mobile device and a first Bluetooth controller comprise program instructions to receive advertisement data from the mobile device.

14 . The computer program product of claim 13 , wherein the advertisement data includes mobile device's address information.

15 . The computer program product of claim 12 , wherein the encrypted communication comprises an encrypted authentication signal.

16 . The computer program product of claim 9 , wherein the program instructions to establish a Bluetooth communication channel comprise program instructions to determine a received signal strength indicator (RSSI) value based on a signal received from the mobile device.

17 . A wireless control module of a vehicle telematics system, comprising:
a first Bluetooth controller configured to communicate with a mobile device via a Bluetooth low energy protocol; and a second Bluetooth controller configured to communicate with the mobile device via a classic Bluetooth protocol, the second Bluetooth controller communicatively coupled to the first Bluetooth controller via a secure connection, wherein the first Bluetooth controller is further configured to establish a Bluetooth communication channel with the mobile device, authenticate the mobile device, establish a secure connection with the second Bluetooth controller, in response to successful authentication of the mobile device, and send authentication credentials of the authenticated mobile device to the second Bluetooth controller.

18 . The wireless control module according to claim 17 , wherein the first Bluetooth controller and the second Bluetooth controller are communicatively coupled to a head unit control module of a vehicle telematics system.

19 . The wireless control module according to claim 17 , wherein the secure connection provides encrypted communication between the first Bluetooth controller and the second Bluetooth controller.
