Bluetooth Profile Fast Connection Aggregation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional Bluetooth profile setup involves exchanging numerous messages across multiple protocol layers, leading to prolonged connection times, often taking several seconds to complete, which is inefficient for modern wireless communication systems.
Innovation Solution
Implementing a method that aggregates individual profile configurations for multiple protocol layers and negotiates profiles with reduced messaging between devices, utilizing a fast connection protocol that includes discovery, negotiation, and setup phases to establish connections in under a second.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If traditional Bluetooth profile setup is used with independent protocol layer configuration, then connection reliability is maintained, but connection time increases to several seconds
Solution Approach 1:
The patent merges multiple independent profile configuration messages into a single aggregated profile configuration message. Instead of exchanging messages layer-by-layer across different protocol stacks (L2CAP, RFCOMM, OBEX, etc.), the invention combines all profile negotiation into one unified message exchange, reducing connection time from several seconds to under one second while maintaining configuration reliability
Solution Approach 2:
The patent performs preliminary aggregation of profile configurations before the actual connection setup. By pre-processing and consolidating all profile descriptors and configuration parameters into a single message structure beforehand, the system eliminates the need for multiple sequential message exchanges during connection establishment, thereby reducing latency without sacrificing configuration completeness
2Productivity
If multiple individual profile configurations are exchanged across protocol layers, then configuration completeness is ensured, but messaging overhead increases
Solution Approach 1:
The patent combines numerous individual profile configuration messages into a single aggregated message that carries all necessary profile descriptors, configuration parameters, and negotiation data. This merging approach reduces the message quantity from dozens of individual exchanges to just one or a few aggregated messages, directly improving connection speed while ensuring all profile configurations are transmitted
Solution Approach 2:
The aggregated profile configuration message serves multiple functions simultaneously: it negotiates L2CAP parameters, configures RFCOMM channels, sets up OBEX services, and establishes other protocol layer settings in a single universal message structure. This multi-functionality eliminates the need for separate specialized messages for each protocol layer, reducing overall messaging overhead

AI summary
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.
