Selective IMS Voice Measurement Reporting for Faster RAT Fallback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices experience delays and interruptions in IMS voice services due to delayed fallback procedures and measurement report events, particularly when switching between radio access technologies (RATs) during IMS voice service scenarios.
Innovation Solution
The electronic device identifies events associated with IMS voice services and deactivates specific measurement report events to prevent unnecessary measurement reports, thereby reducing delays and interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement report events are performed according to configured events, then measurement precision and network optimization are improved, but fallback procedure speed and service continuity deteriorate
Solution Approach 1:
The electronic device performs preliminary identification of IMS voice service events and proactively deactivates corresponding measurement report events before they can trigger unnecessary measurement reports. This preliminary action prevents the sequence where measurement reports would normally be generated, processed, and acted upon, thereby eliminating the time delay while maintaining measurement precision for non-IMS events.
Solution Approach 2:
The measurement report event activation state is made dynamic based on the detected service type. When an IMS voice service event is identified, the device dynamically deactivates specific measurement report events. This dynamic adjustment allows the system to optimize between measurement precision and fallback speed according to current service requirements, resolving the contradiction adaptively.
2Productivity
If measurement report events are performed according to configured events, then network optimization is improved, but service continuity and reliability deteriorate
Solution Approach 1:
The device applies local quality differentiation by treating measurement report events differently based on the service context. For IMS voice services, specific measurement report events are deactivated to ensure service continuity, while other measurement events continue to operate for general network optimization. This localized adjustment resolves the contradiction by optimizing for reliability in the specific context of IMS voice services while maintaining overall network optimization productivity.
Solution Approach 2:
The device implements feedback control by continuously monitoring for IMS voice service events and adjusting the activation state of measurement report events accordingly. When an IMS voice event is detected, the system provides feedback by deactivating relevant measurement events to prevent service interruption. This feedback mechanism ensures service continuity while allowing network optimization to continue through other measurement events.
3Adaptability or versatility
If measurement report events are performed according to configured events, then comprehensive network monitoring is improved, but service speed and responsiveness deteriorate
Solution Approach 1:
The device segments the measurement report events into different categories based on service type. For IMS voice services, specific measurement report events are deactivated to improve service speed, while other measurement events remain active to maintain comprehensive network monitoring for other services. This segmentation allows the system to optimize speed for critical services without sacrificing overall monitoring comprehensiveness.
Solution Approach 2:
The device applies partial action by selectively deactivating only those measurement report events that would interfere with IMS voice service speed, rather than deactivating all measurement events. This partial deactivation maintains comprehensive network monitoring for non-IMS services while improving service response speed for IMS voice services, resolving the contradiction through targeted intervention.
