Wireless Network IMS Prioritization for Unresponsive Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless network cores are inefficient in determining unresponsive Internet Protocol Multimedia Subsystems (IMS) and fail to effectively mitigate the effects of such unresponsiveness, leading to suboptimal voice call handovers and media content delivery.
Innovation Solution
Implementing a prioritization mechanism within the wireless communication network to monitor and rank media content functions based on performance, allowing user equipment to re-register with higher-performing IMS components, thereby ensuring efficient communication and minimizing the impact of unresponsive IMS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the wireless network core uses traditional monitoring methods to detect unresponsive IMS, then the detection process is simple, but the detection accuracy is low and handover efficiency is poor
Solution Approach 1:
The patent applies preliminary action by proactively monitoring IMS responsiveness before service failures occur. The network core continuously checks IMS functionality and prepares handover candidates in advance, rather than reacting only when failures are detected. This allows the system to maintain accurate detection of unresponsive IMS while managing complexity through structured monitoring procedures.
Solution Approach 2:
The patent implements feedback mechanisms where the network core receives status information from IMS components and uses this feedback to determine responsiveness. The system continuously monitors IMS reactions to test signals and adjusts handover decisions based on this feedback loop, improving detection accuracy while maintaining manageable system complexity through standardized feedback protocols.
2Reliability
If the network requires user devices to hand over when IMS is unresponsive, then service continuity is maintained, but the handover process is inefficient and causes service disruptions
Solution Approach 1:
The patent applies preliminary action by pre-identifying alternative IMS components and preparing handover paths before service failures occur. The network core maintains a list of potential handover targets and pre-establishes their responsiveness, enabling rapid handover execution when needed while maintaining high efficiency and service continuity.
Solution Approach 2:
The patent implements dynamics by making the handover process adaptive and flexible. The system dynamically selects handover targets based on real-time IMS responsiveness monitoring and adjusts handover timing and targets according to current network conditions. This dynamic approach improves both service continuity and handover efficiency by avoiding unnecessary handovers and selecting optimal targets.
3Reliability
If the network core does not monitor IMS performance, then the system operation is simple, but the ability to mitigate unresponsive IMS effects is poor
Solution Approach 1:
The patent applies segmentation by dividing the monitoring function into distinct modular components within the network core. Different monitoring procedures are implemented for different IMS functions, and handover decisions are made by separate decision-making modules. This segmentation improves service reliability through comprehensive monitoring while managing complexity by organizing monitoring tasks into manageable, independent modules.
Solution Approach 2:
The patent implements universality by designing a multi-functional monitoring system that can detect various types of IMS failures through standardized procedures. The same monitoring infrastructure handles different IMS components and failure modes, improving service reliability through comprehensive coverage while controlling complexity through reusable, universal monitoring mechanisms.
