Cell Outage Coordination via Priority-Based Action Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In cellular wireless communications networks, simultaneous performance of cell outage compensation (COC) and capacity and coverage optimization (CCO) actions often leads to conflicts, disrupting normal network operations.
Innovation Solution
A method and apparatus that determine a cell needing coordination, compare priorities between COC and CCO actions, and continue the high-priority action while suspending the low-priority action to prevent conflicts and ensure high-priority network optimization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If COC and CCO actions are performed simultaneously for the same cell, then both outage compensation and capacity/coverage optimization are attempted, but conflicts are generated and normal running of important actions cannot be ensured
Solution Approach 1:
The patent changes the operational state parameter of network optimization actions by introducing priority levels (high priority for COC, low priority for CCO). When a cell is identified as needing both COC and CCO actions, the system modifies the execution parameter by suspending the low-priority CCO action while continuing the high-priority COC action, thereby eliminating conflicts and ensuring reliable execution of critical operations.
2Reliability
If COC action is performed to compensate for cell outage, then coverage hole is filled and KPI is maintained, but CCO action may be interrupted causing optimization delays
Solution Approach 1:
The patent establishes a preliminary priority classification system that identifies COC actions as high-priority and CCO actions as low-priority before execution. When both actions target the same cell, the pre-established priority framework automatically determines that COC must be executed first to maintain service availability, and CCO is suspended until the COC action completes, thereby preventing service disruption while still allowing optimization to proceed eventually.
3Productivity
If CCO action is performed to optimize capacity and coverage, then network performance is improved, but COC action may be disrupted causing service degradation
Solution Approach 1:
The patent modifies the execution parameter of network optimization actions by introducing a priority state that distinguishes between high-priority COC actions and low-priority CCO actions. When a cell requires both types of actions, the system changes the operational parameter of the CCO action from 'execute' to 'suspend', ensuring that service-critical COC actions are not disrupted while maintaining the capability to perform efficiency-improving CCO actions when appropriate.

AI summary
The present invention discloses a method and an apparatus for coordinating cell outage compensation and capacity and coverage optimization, and belongs to the communications field. In the present invention, a cell to be coordinated is determined, where the cell is a cell that needs coordination of a COC action and a CCO action; priorities of the COC action and the CCO action are compared, and a high-priority action and a low-priority action are determined in the COC action and the CCO action; and for the cell to be coordinated, the high-priority action continues to be performed, and the low-priority action is stopped from being performed. This effectively solves a problem of a conflict generated when the COC action and the CCO action are performed for the same cell, and ensures normal execution of a network optimization action with a relatively high priority.
