Bluetooth Connection Parameter Reuse for Faster Device Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Bluetooth connection process is delayed due to extensive parameter negotiation and information exchange, which consumes time and resources.
Innovation Solution
A method to determine if the versions of two electronic devices are consistent, allowing direct use of shared Bluetooth connection parameters without exchange, or to identify and exchange only changed parameters when versions differ, thereby simplifying the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parameter negotiation and information exchange are performed according to protocol standard procedure to ensure connection establishment, then connection reliability is improved, but connection time increases
Solution Approach 1:
The patent applies preliminary action by pre-storing Bluetooth connection parameters (such as authentication information, encryption keys, and configuration data) in the parameter storage module before actual connection is needed. When a connection request is received, the system directly retrieves these pre-stored parameters instead of performing complete parameter negotiation, thereby reducing connection delay while ensuring reliability through verified pre-stored data
Solution Approach 2:
The patent extracts only the essential connection parameters from the complete protocol negotiation process. The parameter negotiation module selectively retrieves specific pre-stored parameters (such as authentication credentials and configuration data) rather than performing full parameter exchange, thus reducing the time-consuming information exchange while maintaining necessary connection reliability
2Adaptability or versatility
If complete parameter negotiation is performed each time connection is established, then connection compatibility is improved, but connection speed decreases
Solution Approach 1:
The system performs compatibility verification in advance by storing validated connection parameters from previous successful connections. When a new connection is initiated, the parameter retrieval module directly accesses these pre-validated parameters, avoiding repeated compatibility checks while ensuring device compatibility through proven parameter sets
Solution Approach 2:
The patent uses copying by replicating and storing successful connection parameter sets from previous compatible device interactions. The parameter storage module maintains copies of verified working parameters that can be quickly retrieved and applied to similar connection scenarios, ensuring compatibility without repeating the full negotiation process

AI summary
This application provides a Bluetooth communication system, a Bluetooth connection method, an electronic device, and a storage medium, and relates to the field of communication technologies. When two electronic devices need to establish a Bluetooth connection, whether versions of the two electronic devices are consistent may be first determined, and whether a Bluetooth connection parameter needs to be exchanged is further determined. If the versions are consistent, a Bluetooth connection parameter does not need to be exchanged, and a Bluetooth connection parameter shared by the two devices is directly obtained from a local device to establish the Bluetooth connection. If the two devices each have stored information about a peer device, whether the information about the peer device is changed may be first determined. If the information about the peer device is changed, changed information is exchanged to establish the connection. If the information about the peer device is not changed, no information needs to be exchanged, and the stored information about the peer device is directly invoked to establish the connection. In this way, some information negotiation and exchange procedures in a Bluetooth connection process can be simplified, and a Bluetooth connection speed can be increased.
