Solution Overview

Problem

Manual traffic reassignment in wireless networks is labor-intensive and error-prone, relying heavily on subjective planning experience, which affects the efficiency of network expansion or decommissioning based on traffic volume forecasts.

Innovation Solution

An automated method that calculates offload percentages and selects relief sectors by determining the Traffic Circle Intersection Fraction (TCIF) and using equations to derive offload fractions, thereby objectively determining traffic reassignment between offload and relief sectors.

Engineering Contradictions & Design Principles
