5G Handover Reporting With State-Based Logging and GWUS Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of efficiently reporting handover-related information from a terminal to a base station in mobile communication systems, particularly in 5G networks, and addressing issues related to false wake-up signals due to group wake-up signals (GWUS) in existing signaling methods.
Innovation Solution
A method for a terminal to collect and efficiently report handover information to a base station, including condition-based handover operations, and a mechanism to handle false wake-up signals through terminal grouping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If location information is recorded every time a location update request is received, then location information can be obtained, but unnecessary recording occurs when the mobile station is in idle state causing increased memory usage and processing overhead
Solution Approach 1:
The system dynamically adjusts the recording behavior based on the mobile station's state. When in idle state, the mobile station does not record location information even though location update requests are received. When transitioning to active state, recording is activated. This dynamic state-dependent behavior resolves the contradiction by avoiding unnecessary recording in idle state while ensuring location information is captured when needed.
Solution Approach 2:
The recording parameter is changed based on the mobile station's state parameter. The system monitors whether the mobile station is in idle or active state and adjusts the recording action accordingly. This parameter change approach allows the system to optimize between information completeness and processing efficiency by linking the recording action to the state condition.
2Ease of operation
If the mobile station always records location information, then location tracking is simple, but memory resources are wasted when the mobile station is in idle state
Solution Approach 1:
The recording operation is made dynamic and state-dependent. The mobile station automatically determines whether to record based on its current state (idle or active). This dynamic approach simplifies the operation from the user perspective while optimizing memory usage by avoiding recordings in idle state, thus resolving the contradiction between ease of operation and memory consumption.
Solution Approach 2:
The mobile station autonomously manages its own recording behavior by self-determining whether to record based on its state. The station automatically transitions between recording and non-recording modes without external intervention, making the system self-regulating. This self-service mechanism maintains operational simplicity while reducing unnecessary memory usage.
3Loss of information
If location information is recorded in all states, then complete location data is available, but processing overhead increases when the mobile station is in idle state
Solution Approach 1:
The system implements dynamic recording based on mobile station state. Processing overhead is reduced by avoiding location information recording when the station is in idle state, while maintaining completeness for active state communications. This dynamic approach optimizes the trade-off between data completeness and processing resource consumption.
Solution Approach 2:
The recording parameter is changed based on the mobile station's state parameter. When the state indicates idle condition, the recording parameter is set to false, reducing processing overhead. When in active state, recording is enabled to ensure data completeness. This parameter-based control resolves the contradiction by aligning processing activity with actual communication needs.
