Self-Configuring Handover Reporting for 5G Wireless Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G wireless communication systems face challenges in optimizing handover processes, particularly in recording and reporting successful handover reports (SHR) accurately, which affects radio link failures and network performance, due to unclear activation conditions and encoding formats for different radio access technologies (RATs) during handovers.
Innovation Solution
A method and device for self-optimization and self-configuration in wireless communication systems, where a source node acquires and transmits configuration information related to successful handovers, including threshold values and measurement information, to enable user equipment (UE) to record and report SHR effectively, and a UE generates and transmits SHR based on received configuration information, optimizing handover parameters and reducing radio link failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If handover parameters are optimized to improve network performance, then handover success rate improves, but system complexity increases due to multiple configuration parameters
Solution Approach 1:
The network node automatically determines and configures handover reporting parameters without manual intervention. The source node autonomously selects the appropriate encoding format based on the target RAT type, and the UE self-configures the SHR reporting behavior according to received configuration, eliminating the need for complex manual parameter tuning while achieving optimized handover performance
Solution Approach 2:
The patent dynamically changes configuration parameters based on RAT type. The encoding format parameter is selectively applied: binary encoding for NR target RATs and text encoding for non-NR target RATs. This parameter adaptation allows the system to optimize handover reporting efficiency for different radio access technologies while maintaining manageable configuration complexity through rule-based automation
2Productivity
If successful handover reporting is implemented across multiple RATs, then network optimization capability improves, but encoding format complexity increases due to different RAT requirements
Solution Approach 1:
The patent applies different encoding formats tailored to specific RAT types. Binary encoding is used specifically for NR (New Radio) target RATs where compact representation is critical, while text encoding is used for non-NR target RATs where readability and compatibility are prioritized. This localized quality approach optimizes handover reporting for each RAT's specific requirements without imposing unnecessary complexity across all systems
Solution Approach 2:
Instead of using a single universal encoding format for all RATs, the patent inverts the approach by using different encoding formats for different RAT types. The system determines the target RAT type and selects the encoding format accordingly, rather than forcing all RATs to conform to one encoding scheme. This inversion resolves the complexity issue by matching encoding characteristics to RAT-specific needs
3Measurement precision
If handover configuration information is transmitted to UE, then handover reporting accuracy improves, but signaling overhead increases
Solution Approach 1:
The patent changes the encoding format parameter based on RAT type to optimize the balance between reporting accuracy and signaling overhead. Binary encoding for NR RATs provides compact, efficient representation that reduces signaling overhead while maintaining precision, whereas text encoding for non-NR RATs ensures compatibility and adequate precision without excessive overhead. This parameter adaptation allows each RAT to operate at its optimal efficiency point
