Mediation Device for Multi-Device NFC Connection Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Near Field Communication (NFC) connection handover method is inefficient and prone to misconnections when establishing communication connections between multiple devices, requiring multiple taps and efforts by a handover mediator, especially when devices are far apart or of large size, leading to increased time and effort and potential misconnections.
Innovation Solution
A mediation device acquires and saves connection configuration information of candidate devices, determines the main device and target devices, and matches their configurations to establish secondary communication connections efficiently, reducing the need for multiple taps and preventing misconnections by using NFC for initial configuration acquisition and Bluetooth or Wi-Fi for subsequent connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a handover mediator M is used to assist device A to establish communication connections to N devices B based on NFC, then communication connection can be established between devices, but the handover mediator M needs to move back and forth between device A and N devices B at least N times, increasing time and effort
Solution Approach 1:
The handover mediator M performs preliminary actions by acquiring connection configuration information from all N target devices B in advance through NFC taps, storing this information locally. This preliminary data collection eliminates the need for repeated back-and-forth movements between device A and each target device, significantly reducing the time and effort required for connection establishment.
Solution Approach 2:
The handover mediator M acts as an intermediary that collects and manages connection configuration information from multiple target devices. Instead of direct peer-to-peer NFC communication requiring multiple sequential taps, the mediator consolidates connection data and enables device A to establish connections more efficiently through a single interaction or reduced number of interactions with the mediator.
2Ease of operation
If any terminal ensures all carriers in the message carrier list remain connectable for 2 minutes after sending handover mediation response, then handover can be completed, but misconnection between multiple devices may occur
Solution Approach 1:
The system implements feedback mechanisms where the handover mediator M monitors connection status and provides real-time updates. When connection establishment is successful or fails, the system receives feedback and adjusts the connectable state accordingly, rather than maintaining a fixed 2-minute window that may cause misconnections. This dynamic feedback control ensures connections are established reliably without unintended misconnections between devices.

AI summary
The present invention relates to a communication connection establishment method and a mediation device. The method includes: performing, by a mediation device, a first communication connection to at least three candidate devices, to acquire connection configuration information of the candidate devices, and saving the acquired connection configuration information; before or after or when the mediation device performs the first communication connection to the at least three candidate devices, determining, by the mediation device, that one of the candidate devices is a main device and the other candidate devices are target devices; and matching, by the mediation device, connection configuration information of the main device with connection configuration information of each of the target devices, so that the main device establishes a second communication connection to each of the target devices. According to the communication connection establishment method and the mediation device that are provided in embodiments of the present invention, a mediation device can be used to assist, with less time and effort and based on a first communication connection, a main device to separately establish second communication connections to multiple target devices, and a misconnection between the target devices can be effectively avoided.
