Abstract

Methods for aggregating Bluetooth profiles for faster connection and configuration are disclosed, including transmitting, subsequent to establishing a connection, a request message to a peer device that indicates support of a fast connection protocol for Bluetooth profiles configuration and receiving a response message from the peer device that indicates the peer device supports the fast connection protocol. After pairing with the peer device, a first list of profile descriptors for a plurality of Bluetooth profiles supported by the device may be transmitted to the peer device and a second list of profile descriptors for a plurality of Bluetooth profiles supported by the peer device may be received. A configuration of a plurality of Bluetooth profiles base, at least in part, on a comparison of the first list of profile descriptors to the second list of profile descriptors may be determined and transmitted to the peer device.

First claim

What is claimed is:

1. A wireless station, comprising:
at least one antenna;
at least one radio in communication with the at least one antenna and configured to perform communications via a Bluetooth interface; and
at least one processor in communication with the at least one radio;
wherein the at least one processor is configured to cause the wireless station to:
identify a neighboring device that supports a fast connection protocol;
establish, without negotiation, a logical channel based at least on a channel identifier received from the neighboring device; and
pair, via the logical channel, the wireless station with the neighboring device.

2. The wireless station of claim 1 ,
wherein, to identify the neighboring device that supports the fast connection protocol, the at least one processor is further configured to cause the wireless station to:
transmit, to the neighboring device, a request message indicating support of the fast connection protocol; and
receive, from the neighboring device, a response message indicating that the neighboring device supports the fast connection protocol.

3. The wireless station of claim 1 ,
wherein, to identify the neighboring device that supports the fast connection protocol, the at least one processor is further configured to cause the wireless station to:
transmit, to the neighboring device, a first local channel identification and first maximum transmission unit (MTU) for a first Logical and Link Controls Adaption Protocol (L2CAP) channel; and
receive, from the neighboring device, the channel identifier, wherein the channel identifier comprises a second local channel identification and second MTU for a second L2CAP channel.

4. The wireless station of claim 3 ,
wherein the logical channel is determined based, at least in part, on the first L2CAP channel and the second L2CAP channel.

5. The wireless station of claim 1 ,
wherein the logical channel is an out of band first Logical and Link Controls Adaption Protocol (L2CAP) channel.

6. The wireless station of claim 1 ,
wherein the at least one processor is further configured to cause the wireless station to:
transmit, to the neighboring device, an aggregate of multiple profiles supported by the wireless station; and
receive, from the neighboring device, an aggregate of multiple profiles supported by the neighboring device.

7. The wireless station of claim 6 ,
wherein the aggregate of multiple profiles supported by the wireless station includes one or more of:
Logical and Link Controls Adaption Protocol (L2CAP) channel information for each channel;
radio frequency communication (RFCOMM) channel information if a profile is over RFCOMM;
handsfree service level connection data;
audio/video data transport protocol/advanced audio distribution profile (AVDTP/A2DP) profile information;
audio/video control transport protocol/audio/video remote control profile (AVCTP/AVRCP) profile information; or
advanced accessory control profile (AACP) profile information.

8. The wireless station of claim 7 ,
wherein the L2CAP channel information for each channel includes at least one of a channel identity (ID), protocol and service multiplexers (PSMs), a maximum transmission unit (MTU), or retransmission mode parameters;
wherein the RFCOMM channel information includes one or more of a server channel, a maximum frame size, a flow control model, initial credits, or initiator parameters;
wherein the handsfree service level connection data includes one or more of a version, supported codecs, local features, call indicators, call hold, volume gain, microphone gain, echo cancellation, or vendor specific features parameters;
wherein the AVDTP/A2DP profile information includes one or more of an AVDTP version, an A2DP version, an endpoint list, configuration data per endpoint, signal channel L2CAP information, media channel L2CAP information, or delay report parameters;
wherein the AVCTP/AVRCP profile information includes a version parameter; and
wherein the AACP profile information includes one or more of an advanced accessory profile (AAP) service identifier, a version, an opcode, or features parameters.

9. The wireless station of claim 7 ,
a profile is encoded using a type, length, value (TLV) like type-value format.

10. An apparatus, comprising:
a memory; and
at least one processor in communication with the memory, wherein the at least one processor is configured to:
generate instructions to identify a neighboring device that supports a fast connection protocol;
establish, without negotiation, a logical channel based at least on a channel identifier received from the neighboring device; and
generate instructions to pair, via the logical channel, with the neighboring device.

11. The apparatus of claim 10 ,

generate instructions to transmit, to the neighboring device, a first local channel identification and first maximum transmission unit (MTU) for a first Logical and Link Controls Adaption Protocol (L2CAP) channel; and
receive, from the neighboring device, the channel identifier, wherein the channel identifier comprises a second local channel identification and second MTU for a second L2CAP channel.

13. The apparatus of claim 12 ,
wherein the logical channel is determined based, at least in part, on the first L2CAP channel and the second L2CAP channel.

14. The apparatus of claim 10 ,
