Solution Overview

Problem

The existing method for establishing a link between an access point and a repeater in a wireless distribution system requires manual user input for parameters like channel, MAC address, encryption mode, and cipher key, making the process cumbersome and troublesome.

Innovation Solution

The method automates the link establishment by having the access point and repeater exchange interactive messages to obtain and configure channel information, encryption mode, cipher key, and address information, allowing them to establish a link without manual user input, thereby simplifying the process and optimizing link parameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual configuration method is used for WDS link parameters, then user control and customization are improved, but operation complexity and time consumption increase

Engineering Contradiction:
Improvelink establishment processVSAvoidlink establishment time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The repeater automatically scans channels, obtains channel information, encryption modes, cipher keys, and MAC addresses without user intervention. The system performs self-configuration by exchanging interaction messages with the access point, eliminating the need for manual parameter input while maintaining secure and optimized link establishment.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The repeater pre-scans available channels and pre-obtains channel information, encryption modes, and cipher keys before link establishment is initiated. This preliminary gathering of configuration data accelerates the actual link setup process and reduces the time required for parameter configuration.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If manual configuration method is used for WDS link parameters, then configuration accuracy is improved, but operation complexity increases

Engineering Contradiction:
Improveparameter configuration processVSAvoidconfiguration process complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The system automatically obtains and configures all necessary link parameters including channel information, encryption modes, cipher keys, and MAC addresses through automated interaction messages between the repeater and access point, eliminating complex manual configuration steps while ensuring accurate parameter setup.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

Interaction messages serve as an intermediary mechanism that automatically transfers configuration parameters between the access point and repeater. These messages encapsulate channel information, encryption settings, and authentication data, simplifying the configuration process by handling complex parameter exchange automatically.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If automated channel scanning is implemented, then ease of operation is improved, but energy consumption increases

Engineering Contradiction:
Improvelink establishment processVSAvoidrepeater energy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The repeater performs channel scanning and obtains configuration parameters in advance before the actual link establishment is triggered. This preliminary action allows the system to cache channel information and encryption settings, reducing the frequency and duration of scanning operations during normal operation and thereby lowering overall energy consumption.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Instead of continuous scanning, the repeater performs channel scanning periodically or on-demand when link establishment is initiated. This periodic approach balances the need for up-to-date channel information with energy conservation, scanning only when necessary rather than continuously.

Inventive Principle:
Principle #19Periodic action
