Solution Overview

Problem

In large WLAN deployments, replacing a failed access point requires significant configuration overhead and time, as static identities need to be reconfigured, which disrupts network availability and necessitates skilled IT personnel.

Innovation Solution

A method and system for dynamically assigning an identity to access points based on physical network connection information, using a WLAN management module that discovers the switch and port connection, generates configuration information, and updates the access point's settings automatically, minimizing manual intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If static identity assignment is used for access points, then configuration stability is maintained, but replacement time and configuration overhead increase significantly

Engineering Contradiction:
Improveconfiguration stabilityVSAvoidreplacement time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent implements dynamic identity assignment where access point identities are no longer static but are automatically assigned and updated based on current network conditions and replacement scenarios. The system dynamically generates new identities and configures parameters automatically, transforming the static configuration model into a dynamic one that adapts to device replacements without manual intervention.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system performs preliminary actions by pre-configuring identity assignment mechanisms and parameter sets before actual device replacement occurs. When an access point is replaced, the new device already has the framework for identity assignment in place, allowing immediate configuration without waiting for manual setup, thus reducing replacement time while maintaining stability.

Inventive Principle:
Principle #10Preliminary action

2Manufacturing precision

If manual configuration is performed for each access point, then configuration precision is ensured, but labor requirements and complexity increase

Engineering Contradiction:
Improveconfiguration precisionVSAvoidconfiguration complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent uses copying by creating template parameter sets that can be replicated across multiple access points. Instead of manually configuring each device from scratch, the system copies pre-defined parameter sets and automatically adapts them to individual devices, ensuring configuration precision through standardized templates while reducing the complexity of repeated manual configuration tasks.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system enables self-service by allowing access points to automatically receive and apply configuration parameters without requiring skilled IT personnel for each device. The automated configuration system serves itself by generating, assigning, and applying identities and parameters, thereby reducing labor requirements and operational complexity while maintaining configuration precision through systematic processes.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If skilled IT personnel are deployed for access point configuration, then configuration accuracy is maintained, but operational costs and response time increase

Engineering Contradiction:
Improveconfiguration accuracyVSAvoidresponse time
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent implements self-service automation where the configuration system operates independently without requiring skilled IT personnel for routine access point configuration. The automated system maintains configuration accuracy through pre-defined parameter sets and validation mechanisms, while simultaneously improving response time by eliminating the need to wait for personnel deployment and manual configuration processes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system uses feedback mechanisms to maintain configuration accuracy automatically. By implementing monitoring and validation processes that provide feedback on configuration status, the system can detect and correct issues without human intervention, thereby maintaining precision while improving response time through automated detection and correction cycles.

Inventive Principle:
Principle #23Feedback

AI summary

In a wireless LAN (WLAN) a method and system, for dynamically assigning a configuration identity to a device being connected to the WLAN is provided. An access point (AP) or other device is plugged into a switch port of an Ethernet switch, and discovers its location and the location of a WLAN management module. The device can then request its configuration identity from the WLAN management module by providing its switch and/or port location. When a device in the WLAN needs to be replaced, the method and system enable dynamic assignment of configuration identity for the new device, to ensure that the configuration and identity of the new device matches that of the device it is replacing.
