Network Switching via Intermediary Terminal for Wearables
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network connection methods for wearable devices experience service interruptions when switching from a cellular network to a non-cellular network, disrupting communication.
Innovation Solution
A network switching method that instructs a first terminal to establish a network connection with a network device through a second terminal, where the first terminal is connected to the second terminal via a non-cellular network and the second terminal is connected to the network device via a cellular network, allowing for indirect communication and minimizing service disruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable device directly connects to the network device through cellular network, then communication reliability is improved, but device complexity increases and power consumption rises
Solution Approach 1:
The patent introduces a terminal device as an intermediary between the wearable device and network device. The terminal device receives data from the wearable device via short-range communication and forwards it to the network device through cellular network, thereby reducing the wearable device's complexity and power consumption while maintaining communication reliability
Solution Approach 2:
The communication path is segmented into two parts: short-range communication between wearable device and terminal device, and cellular network communication between terminal device and network device. This segmentation allows each component to use the most appropriate communication method for its specific needs
2Use of energy by moving object
If the wearable device switches from cellular network to non-cellular network, then power consumption is reduced, but service continuity deteriorates
Solution Approach 1:
The terminal device preliminarily establishes a cellular network connection before the wearable device switches to non-cellular network. This preliminary action ensures that when the wearable device disconnects from cellular network, the terminal device is already ready to forward data, thus maintaining service continuity while allowing the wearable device to save power
Solution Approach 2:
The terminal device maintains continuous cellular network connection and data forwarding capability throughout the process, ensuring that the useful action of data transmission continues uninterrupted even when the wearable device switches to power-saving non-cellular mode
