SON Anomaly Coordination via Range Overlap Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional SON coordination solutions fail to properly coordinate network functions during anomaly instances, leading to unidentified improper or erroneous actions by function instances, and lack the ability to roll back actions caused by anomalies, resulting in potential system performance degradation.
Innovation Solution
An apparatus and method that determine the range of an anomaly attribute, check for overlaps with coordinated function instances, and trigger coordination actions to address conflicts, including creating an anomaly function instance, monitoring resolution messages, and deleting the instance upon successful troubleshooting, with actions such as approving, rejecting, or modifying actions requested by function instances.

Engineering Contradiction Analysis
1Extent of automation
If conventional SON coordination solutions are used to manage network functions, then automation and self-configuration are improved, but the system fails to identify and coordinate improper actions during anomaly instances, leading to reliability degradation
Solution Approach 1:
The patent introduces an anomaly coordination function as an intermediary component that mediates between anomaly detection and SON function coordination. This intermediary receives anomaly information, determines affected SON functions, coordinates their actions, and manages rollbacks, thereby maintaining reliability during anomalies while preserving automation.
Solution Approach 2:
The system implements feedback mechanisms where anomaly information is continuously monitored and fed back to the coordination function. The coordination function uses this feedback to identify affected SON functions, adjust their operations, and trigger rollback actions when necessary, ensuring the system responds appropriately to anomaly conditions.
2Productivity
If multiple independent SON function instances operate concurrently to optimize network performance, then productivity and optimization capability are improved, but coordination failures occur during anomalies causing harmful actions
Solution Approach 1:
The anomaly coordination function serves as a mediator that receives information from multiple SON function instances and anomaly detectors. It coordinates their interactions by identifying which SON functions are affected by anomalies and managing their actions to prevent conflicts and harmful effects during anomaly instances.
Solution Approach 2:
The system implements preliminary anti-action by proactively identifying SON functions that may be affected by anomalies before they execute harmful actions. The coordination function determines potential conflicts in advance and triggers rollback actions or prevents execution of problematic SON functions, thereby preventing harmful effects rather than merely responding to them.
3Adaptability or versatility
If SON functions automatically alter configuration parameters to optimize network behavior, then adaptability is improved, but the system lacks ability to roll back actions caused by anomalies
Solution Approach 1:
The system implements preliminary action by recording configuration changes and state information before SON functions execute their optimization actions. When anomalies are detected, the coordination function uses these preliminary records to facilitate quick rollback to previous stable states, thereby maintaining ease of repair while preserving adaptability.
Solution Approach 2:
The system applies discarding and recovering by selectively discarding (rolling back) configuration changes made by SON functions when anomalies are detected. The coordination function identifies which changes to discard and recovers previous stable configurations, enabling the network to recover from anomaly-induced errors while maintaining the ability to adapt during normal operation.
Data Source
AI summary
It is provided a method, comprising determining a range of an attribute of an anomaly; checking if the range of the attribute of the anomaly overlaps with a range of a related attribute of a coordinated function instance; triggering to execute a coordination action on the coordinated function instance if the range of the attribute of the anomaly overlaps with the range of the related attribute of the coordinated function instance, wherein the related attribute of the coordinated function instance is the same as the attribute of the anomaly, or the related attribute of the coordinated function instance and the attribute of the anomaly correspond to each other.
