User Equipment Event Processing for Handover Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In traditional handover processes, there is a hysteresis mechanism that delays the triggering of actions until channel quality-based events are met for a certain duration, which can lead to inefficiencies, especially in high-speed scenarios where timely handovers are critical.
Innovation Solution
An event processing method for User Equipment (UE) that measures and reports signals when multiple configured events meet their trigger conditions, with a timing mechanism to ensure actions are only triggered after the events have been met for a preset duration, allowing for efficient handover operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hysteresis mechanism is used to delay triggering actions until events are met for a certain duration, then the reliability of handover is improved, but the response time deteriorates
Solution Approach 1:
The patent applies dynamics by making the hysteresis duration configurable and adjustable based on scenario requirements. The network can dynamically set different time durations for different events and UEs, allowing the system to adapt between reliability-focused configurations (longer durations) and speed-focused configurations (shorter durations), thus resolving the contradiction between handover reliability and response time.
2Measurement precision
If multiple events are monitored with individual triggering conditions, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The patent merges multiple individual event triggering mechanisms into a unified event processing framework. The network configures multiple events with their respective triggering conditions, but the UE processes them through a single integrated measurement and reporting mechanism, reducing device complexity while maintaining precise detection of each event type.
Solution Approach 2:
The patent creates a universal event processing mechanism that handles multiple different event types (A1, A2, A3, etc.) through a common framework. The same measurement and reporting infrastructure serves multiple purposes, allowing precise monitoring of various channel quality metrics without proportionally increasing device complexity.
