Mobility History Reporting in New Radio Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in New Radio (NR) networks, lack efficient mechanisms for mobility history reporting, which hinders optimal resource management and network planning due to insufficient tracking of user equipment (UE) mobility patterns.
Innovation Solution
A wireless node configured to receive and transmit mobility history reports containing cell identities and mobility parameters, such as entry and exit times, to a parent node, enabling periodic, semi-persistent, event-triggered, or dynamically requested reporting, facilitating better network management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If mobility history reporting is implemented in NR networks, then network resource management and optimization are improved, but system complexity and signaling overhead increase
Solution Approach 1:
The mobility history report is segmented into multiple information elements including cell identity pairs, mobility parameters, and duration indicators. This segmentation allows the system to manage complex mobility information in structured, manageable units that can be processed efficiently by the network
Solution Approach 2:
The mobility history reporting mechanism is designed to serve multiple functions simultaneously: it provides mobility pattern data for resource management, supports network optimization decisions, and enables tracking of UE behavior across different cells and time periods
2Measurement precision
If detailed mobility history information is collected and reported, then network optimization and resource allocation are enhanced, but information processing overhead and signaling load increase
Solution Approach 1:
The patent extracts only the essential mobility history information elements needed for network optimization, such as cell identity pairs, entry/exit times, and duration parameters. This selective extraction reduces signaling overhead while maintaining the precision needed for effective network management
Solution Approach 2:
The reporting mechanism allows for configurable parameters including reporting triggers, time windows, and cell selection criteria. These parameter changes enable the system to adjust the amount and type of mobility information reported based on specific network conditions and optimization needs
