NFC Identity Authentication for Wireless Link Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technology for connecting multiple terminal devices with a Bluetooth headset requires users to repeatedly perform pairing operations on each device, making the process complex and inefficient.
Innovation Solution
A method where a first terminal device establishes a communication connection with a second terminal device and performs identity authentication on a third terminal device through near-field communication (NFC), then shares communication link information with the third terminal device using short-range wireless technology, allowing the third terminal device to connect to the second terminal device without additional user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users repeatedly perform pairing operations on each terminal device to connect with a Bluetooth headset, then connection reliability is ensured, but operation complexity increases and pairing efficiency decreases
Solution Approach 1:
The first terminal device acts as an intermediary that has already established a connection with the Bluetooth headset. It uses this existing connection to share pairing information with the third terminal device, eliminating the need for the third device to perform independent pairing operations while maintaining connection reliability through the trusted first device's established link
Solution Approach 2:
The first terminal device performs the pairing action in advance by establishing its own connection with the Bluetooth headset before needing the third terminal device to connect. This preliminary action creates reusable pairing information that can be shared with other devices, avoiding repeated pairing operations
2Reliability
If users repeatedly perform pairing operations on each terminal device, then connection reliability is ensured, but pairing efficiency decreases
Solution Approach 1:
The first terminal device serves as a mediator that leverages its existing connection with the Bluetooth headset to provide pairing information to the third terminal device. This intermediary approach maintains connection reliability through the first device's established link while significantly improving pairing efficiency by eliminating redundant pairing operations
Solution Approach 2:
The first terminal device's connection with the Bluetooth headset serves multiple functions: it establishes the initial connection, provides pairing information for other devices, and enables multiple terminal devices to connect to the same Bluetooth headset without requiring separate pairing operations for each device

AI summary
This application is applicable to the field of communication technologies, and provides an information sharing method, a terminal device, a storage medium, and a computer program product. The information sharing method includes: After a first terminal device establishes a communication connection to a second terminal device, when the first terminal device approaches a third terminal device, the first terminal device performs identity authentication on the third terminal device through near field communication NFC. When determining that an identity of the third terminal device is valid, the first terminal device sends communication link information to the third terminal device by using a short-range wireless communication technology, so that after receiving the communication link information, the third terminal device establishes a communication connection to the second terminal device by using the communication link information when detecting the second terminal device. In the foregoing solution, when the first terminal device approaches the third terminal device, a communication connection can be quickly and conveniently established and information sharing can be implemented. This can simplify an operation step of establishing the communication connection between the third terminal device and the second terminal device.
