Solution Overview
Problem
The increased use of multiple sectors for mobile stations in wireless communication sessions leads to a higher risk of dropped calls and resource-based service impairments due to excessive resource usage, which existing technologies fail to adequately address.
Innovation Solution
A method and system that monitor resource usage in each sector, identify high usage sectors, and apply a predictive algorithm to determine if mobile stations can continue their communication sessions without using these sectors, thereby optimizing resource allocation and maintaining service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile stations use multiple sectors for communication sessions to achieve soft handoff gain, then signal quality and reliability are improved, but resource usage increases leading to higher risk of dropped calls and service impairments
Solution Approach 1:
The system dynamically adjusts the active set of sectors for each mobile station based on real-time resource usage conditions. When resource usage thresholds are exceeded, the network controller automatically removes high-usage sectors from the active set, allowing the system to adapt resource allocation dynamically while maintaining communication reliability through selective sector management
Solution Approach 2:
The invention changes the parameter of active set composition by removing specific high-usage sectors when resource thresholds are exceeded. This parameter change allows the system to control resource consumption while maintaining soft handoff benefits through selective sector inclusion, directly addressing the contradiction between resource usage and communication reliability
2Reliability
If the network maintains all sectors in the active set to maximize soft handoff gain, then signal-to-noise ratio is improved, but resource-based service impairments increase
Solution Approach 1:
The system extracts high-usage sectors from the active set when resource usage exceeds predefined thresholds. This selective removal eliminates the harmful effect of resource-based service impairments while preserving soft handoff gain from remaining sectors, directly resolving the contradiction between signal quality and service impairments
Solution Approach 2:
The network controller continuously monitors resource usage metrics and provides feedback to adjust the active set composition. When resource usage indicates potential service impairments, the system responds by removing problematic sectors, creating a feedback loop that maintains signal quality while preventing service degradation
3Productivity
If resource usage monitoring and predictive algorithms are implemented to manage sector usage, then resource allocation efficiency is improved, but system complexity increases
Solution Approach 1:
The system implements self-service through automated resource usage monitoring and predictive algorithms that independently manage sector allocation without requiring manual intervention. The network controller automatically identifies high-usage sectors and adjusts active sets based on predefined thresholds and predictive analytics, improving resource efficiency while containing complexity through automation rather than manual processes

AI summary
A controller monitors resource usage in each of a plurality of sectors and identifies any sector with resource usage that exceeds a threshold value as a high usage sector. The controller evaluates the mobile stations in its area and identifies any mobile station that is using a high usage sector and at least two other sectors for a communication session as a candidate mobile station. The controller applies a predictive algorithm to determine whether any candidate mobile station is able to continue its respective communication session without using its respective high usage sector. In this determination, the signal levels that a mobile station reported for the sectors in its active set, other than the high usage sector, may be used to calculate a combined signal level. If the combined signal level exceeds a predefined value, the mobile station is instructed to drop the high usage sector.
