Network Handover Driver Filtering for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-mode wireless terminal equipment, frequent network handovers between different networks, such as 2G and 3G, lead to increased power consumption due to repeated modifications of network-connection icons and disruptions in user experience.
Innovation Solution
A method and system for network handover that involves a driver judging whether a network-disconnected message is sent from a Connection Manager (CM), reporting appropriate signaling to the operating system to prevent repeated icon modifications, and storing or emptying IP, subnet, and default gateway parameters to maintain a consistent network state display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the equipment automatically registers to the currently found network when it is superior to the original network, then the network connection quality is improved, but the network-connection icons are modified repeatedly causing increased power consumption
Solution Approach 1:
The patent introduces a driver as an intermediary component between the network handover process and the operating system. The driver intercepts network-disconnected messages, determines their source (CM or not), and selectively reports to the operating system. This intermediary mechanism prevents the operating system from receiving unnecessary disconnection notifications during normal handovers, thereby avoiding repeated icon modifications and reducing power consumption while maintaining network connection quality.
2Adaptability or versatility
If the equipment hands over frequently between 2G and 3G networks in areas with poor 3G coverage, then the network adaptability is improved, but the network-connection icons are modified by the system repeatedly increasing power consumption
Solution Approach 1:
The driver acts as a smart intermediary that filters network status messages during frequent handovers. By checking whether disconnection messages originate from the CM, the driver prevents the operating system from processing redundant handover notifications, thereby reducing the frequency of icon modifications and power consumption while allowing the equipment to adapt freely between 2G and 3G networks.
Solution Approach 2:
The patent changes the parameter of message filtering based on the source identification. When the disconnection message is not from CM (indicating a normal handover), the driver changes the reporting parameter to suppress the notification to the operating system. This parameter change mechanism allows the system to maintain network adaptability while reducing unnecessary operations that consume power.
3Measurement precision
If the driver reports network disconnection to the operating system for every network-disconnected message, then the network state accuracy is improved, but the operating system modifies icons repeatedly causing user experience degradation
Solution Approach 1:
The driver serves as an intelligent intermediary that maintains network state accuracy by selectively reporting only genuine disconnections (those from CM) to the operating system. It filters out handover-related disconnection messages, preventing the operating system from modifying icons repeatedly. This selective reporting mechanism preserves measurement precision for actual disconnections while eliminating spurious notifications that degrade user experience.
Data Source
AI summary
The disclosure provides a method and a system for network handover. The method includes: during a process that equipment hands over from a current network to another network, a driver receiving a network-disconnected message, and judging whether the network-disconnected message is sent from a Connection Manager (CM); if the network-disconnected message is sent from the CM, the driver reporting, to an operating system, a first signalling which identifies that the current network is disconnected; and if the network-disconnected message is not sent from the CM, the driver reporting, to the operating system, a second signalling which identifies that the current network is connected. By the adoption of the method and the system, power consumption of the equipment can be reduced.
