Bluetooth Address Sharing for Fast Pairing

Solution Overview

Problem

Existing Bluetooth (BT) communication technologies face challenges when establishing connections between devices without a previous communication history, leading to increased time and load for establishing connections.

Innovation Solution

An electronic device is equipped with communication circuitry to support BT communication, storing a first BT address and a second BT address. It establishes a connection with a first external device using the first BT address, then transmits a connection request using the second BT address if the first device accepts a reconnection request, and stores information about the acceptance or decline of this request.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If the second external electronic device uses the shared information about the first external electronic device to establish BT communication, then the connection establishment time is reduced, but the first external electronic device may refuse the connection request if it does not recognize the second device's address

Engineering Contradiction:

Improveconnection establishment timeVSAvoidconnection acceptance reliability

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The patent performs preliminary actions by having the first external electronic device pre-approve a list of electronic devices that are allowed to connect without going through the full inquiry and pairing process. When a second device attempts to connect, the first device checks if the second device is in the pre-approved list, enabling direct connection if approved, thus reducing connection time while maintaining security through advance authorization.

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the first external electronic device performs an inquiry process to obtain the unique address of the second external electronic device, then the connection can be established with unknown devices, but the time and processing load increase significantly

Engineering Contradiction:

Improveability to connect with unknown devicesVSAvoidconnection establishment efficiency

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent performs preliminary actions by having the first external electronic device pre-approve a list of electronic devices that are allowed to connect without going through the full inquiry and pairing process. When a second device attempts to connect, the first device checks if the second device is in the pre-approved list, enabling direct connection if approved, thus reducing connection time while maintaining security through advance authorization.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent uses sharing of electronic device information between devices. The electronic device that has established communication with the first external electronic device shares information about the first device (including its unique address and connection parameters) with the second external electronic device. This copied information allows the second device to initiate connection without performing a full inquiry process, thereby improving connection efficiency while maintaining the ability to connect with previously unknown devices.

Inventive Principle:

Principle #26Copying

3Ease of operation

If the electronic device shares BT communication information with the second external electronic device, then the connection process is simplified, but information security may be compromised if the shared information is misused

Engineering Contradiction:

Improveconnection process simplicityVSAvoidinformation security risk

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent performs preliminary actions by having the first external electronic device pre-approve a list of electronic devices that are allowed to connect without going through the full inquiry and pairing process. When a second device attempts to connect, the first device checks if the second device is in the pre-approved list, enabling direct connection if approved, thus reducing connection time while maintaining security through advance authorization.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms where the first external electronic device monitors connection attempts and can dynamically adjust the approval status of devices in its pre-approved list. The device receives feedback about connection outcomes and uses this information to update its authorization decisions, thereby maintaining security while enabling simplified connections for trusted devices.

Inventive Principle:

Principle #23Feedback

AI summary

An electronic device is provided to include a user interface, a communication circuitry that supports Bluetooth (BT) communication and store a first BT address, a processor operatively connected with the user interface and the communication circuitry, and a memory operatively connected with the processor. The memory stores instructions that, when executed, cause the processor to establish a communication connection with a first external electronic device based on the first BT address, end the communication connection with the first external electronic device, receive a reconnection request based on the first BT address from the first external electronic device, transmit a communication connection request to the first external electronic device based on a second BT address different from the first BT address, using the communication circuitry in response to the reconnection request, and store information about whether the first external electronic device accepts or declines the communication connection request in the memory.
