Separating Fixable and Unfixable Handover KPIs

The patent segments handover failures into two distinct categories: fixable too-late handovers and unfixable too-late handovers. This segmentation is achieved by dividing the handover failure analysis into separate evaluation paths based on specific criteria (signal strength thresholds, handover timing, and cause identification), allowing each type to be handled with appropriate optimization strategies rather than treating all failures uniformly.

The patent extracts unfixable too-late handover events from the general handover failure pool by identifying specific characteristics (such as signal strength below threshold, rapid signal degradation patterns, and inability to meet handover timing requirements). These extracted events are then separately reported and excluded from standard MRO optimization processes, preventing them from negatively impacting network performance metrics.

The patent implements segmentation in MRO processing by creating distinct handling paths for fixable and unfixable handover failures. Fixable failures continue to receive standard MRO treatment with offset adjustments and parameter optimizations, while unfixable failures are separately identified, reported, and excluded from optimization loops, maintaining processing efficiency while protecting network performance.

The patent applies local quality by selectively recording and reporting filter measurements only for handover failures that meet specific unfixable criteria. Rather than universally reporting all handover failure measurements, the system evaluates each failure against defined thresholds and characteristics, reporting detailed measurements only when unfixable too-late handover conditions are detected, thus minimizing unnecessary signaling overhead while maintaining analysis accuracy.
