Abstract

Aspects of a method and system for a distributed Bluetooth® Host Architecture may include combining a single main Bluetooth® host with subsidiary Bluetooth® hosts to form a distributed Bluetooth® processing entity that operates as a single Bluetooth® host for a Bluetooth® host controller. An active data connection may be handed over between the main Bluetooth® host and the subsidiary Bluetooth® hosts, where the active data connection may be between the Bluetooth® host controller and the distributed Bluetooth® entity. The active data connection may be an Asynchronous connection-less (ACL) link or a Synchronous Connection-Oriented (SCO) link. Layers of a protocol stack of the main Bluetooth® host may be synchronized with one or more of the subsidiary Bluetooth® hosts to achieve hand over.

Claims

1. A method for processing signals in a wireless communication system, the method comprising:

combining a single main Bluetooth®

host with a plurality of subsidiary Bluetooth®

hosts to form a distributed Bluetooth®

processing entity that operates as a single Bluetooth®

host for a Bluetooth®

host controller.

2. The method according to claim 1, comprising handing over an active data connection between said main Bluetooth®

host and one of said plurality of subsidiary Bluetooth®

hosts.

3. The method according to claim 2, wherein said active data connection is between said Bluetooth®

host controller and said distributed Bluetooth®

entity.

4. The method according to claim 2, wherein said active data connection comprises an Asynchronous connection-less (ACL) link.

5. The method according to claim 2, wherein said active data connection comprises a Synchronous Connection-Oriented (SCO) link.

6. The method according to claim 2, comprising synchronizing layers of a protocol stack of said main Bluetooth®

host with one or more of said plurality of subsidiary Bluetooth®

hosts to achieve said handing over.

7. The method according to claim 1, wherein said main Bluetooth®

host and said plurality of subsidiary Bluetooth®

hosts comprise a Host Controller Interface (HCI) layer.

8. The method according to claim 7, comprising routing data arriving at said HCI layer to at least one of:

said plurality of subsidiary Bluetooth®

hosts and said main Bluetooth®

host.

9. The method according to claim 6, wherein said single main Bluetooth®

host comprises an augmented feature set to perform said synchronizing of said layers to achieve said handing over.

10. The method according to claim 2, wherein said plurality of subsidiary Bluetooth®

hosts comprise a limited feature set that only maintains said active data connection.

11. A system for processing signals in a wireless communication system, the system comprising:

one or more circuits that enable the combination of a single main Bluetooth®

host with a plurality of subsidiary Bluetooth®

hosts to form a distributed Bluetooth®

processing entity that operates as a single Bluetooth®

host for a Bluetooth®

host controller.

12. The system according to claim 11, wherein said one or more circuits hand over an active data connection between said main Bluetooth®

host and one of said plurality of subsidiary Bluetooth®

hosts.

13. The system according to claim 12, wherein said active data connection is between said Bluetooth®

host controller and said distributed Bluetooth®

entity.

14. The system according to claim 12, wherein said active data connection comprises an Asynchronous connection-less (ACL) link.

15. The system according to claim 12, wherein said active data connection comprises a Synchronous Connection-Oriented (SCO) link.

16. The system according to claim 12, wherein said one or more circuits synchronize layers of a protocol stack of said main Bluetooth®

host with one or more of said plurality of subsidiary Bluetooth®

hosts to achieve said handing over.

17. The system according to claim 11, wherein said main Bluetooth®

host and said plurality of subsidiary Bluetooth®

hosts comprise a Host Controller Interface (HCI) layer.

18. The system according to claim 17, wherein said one or more circuits route data arriving at said HCI layer to at least one of:

said plurality of subsidiary Bluetooth®

hosts and said main Bluetooth®

host.

19. The method according to claim 16, wherein said single main Bluetooth®

host comprises an augmented feature set to perform said synchronizing of said layers to achieve said handing over.

20. The method according to claim 12, wherein said plurality of subsidiary Bluetooth®

hosts comprise a limited feature set that only maintains said active data connection.
