Network Handover Timer for Seamless Home Network Restoration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
User equipment cannot automatically switch to another network when the home network is unavailable due to natural disasters or other reasons, leading to communication interruptions.
Innovation Solution
A network handover method that involves a terminal receiving a periodic network detection timer value, periodically detecting the signal strength of the home network, and sending a restoration report to enable a seamless switch back to the home network once it is restored, using a handover module to manage the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal continuously monitors the home network signal strength, then the reliability of network restoration is improved, but the energy consumption increases
Solution Approach 1:
The terminal performs periodic network detection at predetermined intervals rather than continuous monitoring. The network detection timer triggers detection cycles, allowing the terminal to balance between reliable network restoration detection and energy conservation by sleeping between detection periods.
Solution Approach 2:
The terminal autonomously manages its own network detection schedule using local timing mechanisms and stored detection parameters. The handover module configures detection intervals based on network conditions, enabling the terminal to self-regulate energy consumption while maintaining restoration reliability.
2Speed
If the terminal performs frequent network detection, then the speed of network restoration is improved, but the energy consumption increases
Solution Approach 1:
The system implements periodic network detection with configurable intervals that balance restoration speed and energy consumption. The detection frequency is adjusted based on network conditions and service requirements, allowing fast restoration when needed while conserving energy during stable periods.
Solution Approach 2:
The detection interval parameter is dynamically adjusted based on network conditions, service type, and priority levels. Critical services may trigger more frequent detection, while non-critical services use longer intervals, optimizing the balance between restoration speed and energy usage.
3Reliability
If the terminal implements automatic network switching capability, then the communication continuity is improved, but the device complexity increases
Solution Approach 1:
The handover module integrates multiple functions including network detection, signal strength measurement, automatic switching decision-making, and timer management into a single unified component. This multi-functional design improves communication continuity while minimizing the increase in overall device complexity by consolidating control functions.
Solution Approach 2:
The automatic network switching system operates autonomously once configured, with the handover module independently monitoring networks, evaluating conditions, and executing switches without user intervention. This self-service capability ensures communication continuity while reducing the complexity of user interaction and control interfaces.

AI summary
The present invention discloses a network handover method and an apparatus, where the method includes: after a terminal is handed over from a home network to a redundant network, receiving, by the terminal, a value of a periodic network detection timer that is sent by a handover module, where the value of the periodic network detection timer is determined by a subscription management device according to a policy and sent to the handover module, or the value of the periodic network detection timer is preset by the handover module; periodically detecting, by the terminal, signal strength of the home network of the terminal according to the value of the periodic network detection timer; and if it is detected that the signal strength of the home network of the terminal is restored, sending a home network restoration report to the handover module, so that the handover module disable an operational profile of the redundant network and enables an operational profile of the home network of the terminal.
