Wireless Handover Prevention Mechanism for Battery Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices from one network operator are often denied access to communication networks controlled by another operator, leading to repeated handover requests that drain battery life without successful handovers, due to authorization issues and strong signal detection.
Innovation Solution
Implementing a handover prevention mechanism that sets signal strength thresholds and sends rejection responses to prevent unauthorized handovers, and setting a handover prevention value to limit further requests when the signal strength of the first access node meets specific thresholds, thereby conserving battery life and reducing network resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless device continuously requests handover to the second access node, then the device can detect and attempt to access stronger signal, but the battery level is rapidly drained due to repeated failed requests
Solution Approach 1:
The system applies preliminary anti-action by implementing a handover prevention mechanism that proactively blocks unauthorized handover requests before they are executed. When the wireless device sends a handover request to the second access node, the system detects the unauthorized status and sends a handover prevention value, preventing the harmful repeated handover attempts before they can drain the battery.
2Adaptability or versatility
If the wireless device attempts repeated handovers to the second access node, then the device can try to establish connection, but network resources are wasted due to denied access
Solution Approach 1:
The system implements feedback by monitoring handover requests and providing information about authorization status. The system detects when a wireless device from the first network operator requests handover to the second access node, determines the device is unauthorized, and sends a handover prevention value back to the device, creating a feedback loop that prevents resource waste.
3Adaptability or versatility
If the system allows all handover requests, then the wireless device can access any available network, but unauthorized devices can access networks they are not permitted to use
Solution Approach 1:
The system uses an intermediary mechanism (the handover prevention value) that mediates between the wireless device's handover request and the actual handover execution. This intermediary layer checks authorization status and selectively permits or blocks handovers, allowing legitimate access while preventing unauthorized access without completely restricting network access flexibility.

AI summary
In systems and methods of controlling wireless device communication, a first request is received for a performance of a handover of a wireless device from a first access node shared by a first network operator and a second network operator to a second access node controlled only by the second network operator. A rejection response is sent preventing the performance of the handover, and a handover prevention value is set to prevent the sending of a second request for the performance of a handover of the wireless device from the first access node to the second access node.
