Terminal Device Network Search Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for terminal devices to switch between RATs are inefficient, often causing devices to remain in low-RAT networks due to improper network configurations or inadequate switching triggers, leading to suboptimal data access speeds and increased power consumption.
Innovation Solution
The method involves an intelligent terminal system that initiates a search for a high-priority network when the user disconnects from a current hotspot, prioritizing networks based on stored lists and searching in descending order of priority, thereby optimizing the transition to higher-RAT networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a periodic search mode is used to search for high-RAT networks, then the terminal device can autonomously initiate searching when a timer expires, but this causes power waste when the user does not move and delays searching when the user actually moves to an area with 4G/3G coverage
Solution Approach 1:
The terminal device performs a preliminary judgment on whether the user is in a moving state before initiating the periodic search for high-RAT networks. By detecting movement status in advance, the system activates searching only when necessary, avoiding unnecessary power consumption during stationary periods while ensuring timely search initiation when the user moves to areas with 4G/3G coverage.
2Stability of the object's composition
If the terminal device remains in a low-RAT network due to improper network configuration or switching not being triggered, then the device can maintain stable connection, but the data service connection speed and network access speed are lower compared to high-RAT networks
Solution Approach 1:
The terminal device dynamically adjusts its network searching behavior based on user movement status. When the user is detected to be in a moving state, the system actively searches for high-RAT networks (4G/3G) to improve data access speed. When stationary, the system maintains the current low-RAT connection to ensure stability, thus dynamically optimizing the balance between connection stability and data access speed.
3Productivity
If the terminal device performs blind searching for high-RAT networks without determining user movement state, then the device can potentially find higher speed networks, but unnecessary searches waste power and timely searching is delayed
Solution Approach 1:
The terminal device implements a feedback mechanism by continuously monitoring user movement status and using this information to control the periodic search function. The movement detection provides feedback that triggers or suppresses network searching, ensuring that searching is performed efficiently only when the user is moving, thereby improving network switching efficiency while avoiding unnecessary power consumption during stationary periods.

AI summary
This application provides a method for triggering a search for a high-RAT network. When it is detected that Wi-Fi of a terminal device is disconnected, a terminal device moves out of an elevator, or a terminal device moves to another location with a comparatively good signal, the terminal device can be automatically triggered to start background searching for a network, and attempt to camp on and register with the high-RAT network.
