SPCell Change Report Configuration for 5G Handover Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems lack an effective mechanism for configuring a successful Primary Secondary Cell (PSCell) change report, particularly in scenarios where the PSCell change is initiated from either the Master Node (MN) or the Secondary Node (SN), due to insufficient information exchange between MN and SN, making it difficult to set proper thresholds for timers like T310 and T312, which are crucial for optimizing handover interruptions.
Innovation Solution
The proposed solution involves obtaining and determining the configuration of a Successful Primary Secondary Cell Change Report (SPCR) by exchanging information related to timer configurations and measurement settings between the MN and SN, allowing for the optimization of PSCell change decisions and minimizing interruptions during inter-SN PSCell changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If information exchange between MN and SN is insufficient, then the system cannot configure SPCR properly, but increasing information exchange complexity increases system complexity
Solution Approach 1:
The patent extracts the essential information needed for SPCR configuration (timer values T310 and T312, measurement configurations) from the complex MN-SN interaction and focuses the information exchange mechanism on only these critical parameters. This allows proper SPCR configuration without requiring comprehensive information exchange between MN and SN, thus resolving the contradiction between reliability and system complexity.
2Loss of time
If timer thresholds are not properly set, then handover interruptions cannot be optimized, but determining appropriate thresholds requires additional measurement and analysis
Solution Approach 1:
The patent implements a feedback mechanism where the SN provides measurement configurations and timer value recommendations to the MN based on observed handover performance. The MN uses this feedback to adjust timer thresholds T310 and T312, optimizing handover interruption times. This feedback loop enables automatic threshold optimization without requiring complex manual analysis or additional measurement infrastructure.
3Adaptability or versatility
If SPCR configuration is only supported for MN-initiated changes, then SN-initiated changes cannot be optimized, but extending support to both types increases configuration complexity
Solution Approach 1:
The patent designs the SPCR configuration mechanism to be universal, supporting both MN-initiated and SN-initiated PSCell changes through a unified configuration approach. The SN can provide timer configurations and measurement settings that apply regardless of which node initiates the change, eliminating the need for separate configuration mechanisms for different initiation types and thus avoiding increased complexity while maintaining versatility.
