Wireless Device Group Pairing for Reliable Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, when data needs to be transmitted from a data source device to multiple wireless devices, the failure of connection between the data source device and a primary wireless device can lead to low communication reliability, as other devices depend on this primary connection for data transmission.
Innovation Solution
A method where a first device in a device group pairs with a data source device using a group identifier to obtain pairing information, which is then shared with other devices in the group, allowing them to establish connections with the data source device without needing to pair individually, ensuring communication reliability even if the first device malfunctions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data source device transmits data to multiple wireless devices through a primary wireless device, then data transmission is simplified, but communication reliability deteriorates due to single point of failure
Solution Approach 1:
The patent segments the connection structure by dividing wireless devices into device groups, where each group has multiple devices that can independently connect to the data source device. This breaks the single primary device dependency into multiple independent connection paths, resolving the contradiction between simplified connection structure and communication reliability.
Solution Approach 2:
The patent changes the connection parameter from single-point connection to multi-point connection. By enabling multiple wireless devices within a device group to simultaneously establish connections with the data source device using group identifiers, the system transforms the vulnerable single-path connection into redundant multi-path connections, improving reliability while maintaining structural simplicity.
2Reliability
If each wireless device pairs individually with data source device, then connection reliability improves, but pairing time and power consumption increase
Solution Approach 1:
The patent implements preliminary action by pre-establishing device groups and assigning group identifiers before actual data transmission. When a wireless device needs to connect, it can immediately use the pre-configured group identifier to establish connection without undergoing individual pairing procedures, thus reducing pairing time while maintaining reliable connections through the group-based authentication mechanism.
3Reliability
If user intervention is required for pairing, then connection security improves, but user experience and automation deteriorate
Solution Approach 1:
The patent enables self-service by allowing wireless devices to automatically perform connection establishment using group identifiers. The devices autonomously discover each other, authenticate through the group identifier mechanism, and establish connections without requiring user intervention for pairing operations, thereby improving user experience while maintaining security through the group-based authentication system.

AI summary
Methods and apparatuses for communication include: after a data source device discovers a first device in a device group based on a group identifier, pairing the first device with the data source device based on the group identifier to obtain pairing information; transmitting a notification message from the first device to one or more other devices in the device group, the notification message including an instruction to update a status of each of the one or more other devices in the device group to be invisible to a device outside the device group; and providing the pairing information to a second device in the device group, the pairing information being used for establishing a connection between the second device and the data source device.
