Wearable Network Handover via Pre-Established Direct Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Network connection switching in wearable devices causes service interruptions during transitions between cellular and non-cellular networks.
Innovation Solution
A network switching method that involves a first terminal establishing a connection to a network device through a second terminal and instructing the second terminal to release its connection to the first terminal, ensuring service continuity by transitioning from a non-cellular to a cellular connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wearable device uses a non-cellular network to connect to the network device through a terminal, then power consumption is reduced and network coverage is extended, but service interruptions occur during network switching
Solution Approach 1:
The network device establishes a preliminary direct connection with the first terminal (wearable device) before the terminal switches from non-cellular to cellular network. This preparatory action ensures that when the network type changes, the connection can be seamlessly maintained through the pre-established cellular connection, eliminating service interruptions during network switching.
Solution Approach 2:
The terminal acts as an intermediary that coordinates the network switching process. It manages the transition from non-cellular network connection through itself to cellular network direct connection to the network device, ensuring that the wearable device maintains continuous service availability throughout the switching process.
2Reliability
If the terminal establishes a direct cellular network connection to the network device, then service continuity is improved, but power consumption increases and network coverage flexibility is reduced
Solution Approach 1:
The system dynamically switches between two connection modes: non-cellular network connection through the terminal (for normal operation with lower power consumption) and cellular network direct connection (for ensuring service continuity during switching). The wearable device adapts its connection strategy based on operational requirements, using the cellular connection primarily during network switching events rather than continuously, thus balancing power consumption with service reliability.
3Adaptability or versatility
If the wearable device switches between non-cellular and cellular networks, then network adaptability is improved, but connection stability deteriorates due to service interruptions
Solution Approach 1:
The network device proactively establishes a cellular connection with the wearable device before the terminal initiates network switching. This preliminary action creates a stable backup connection that ensures continuity when transitioning from non-cellular to cellular network, maintaining connection stability throughout the switching process while preserving network type flexibility.
