Solution Overview

Problem

Existing systems for storing and processing data in wireless local area networks (WLANs) inefficiently maintain and update client-roaming information for both roaming and stationary clients, leading to unnecessary burdens on network resources.

Innovation Solution

Implementing a system with a roaming-state determination and prediction module that selectively maintains and updates only the records required for roaming services, using a client-information database and optimized record-handling system to classify clients as roaming or stationary, thereby optimizing data storage and processing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system maintains and updates client-roaming information for all clients (both roaming and stationary), then complete client information is available for all possible scenarios, but network resources are unnecessarily burdened

Engineering Contradiction:
Improveclient information availabilityVSAvoidnetwork resource overhead
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent extracts and maintains only the specific client-roaming information that is actually needed for roaming clients, rather than maintaining all possible client information for all clients. The system selectively stores roaming-related data elements only when roaming services are required, removing the unnecessary burden of maintaining complete client information for stationary clients.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system applies different information maintenance strategies to different client types: roaming clients receive full roaming information maintenance while stationary clients have minimal or no roaming information maintained. This local differentiation optimizes network resources by matching information storage with actual service requirements.

Inventive Principle:
Principle #3Local quality

2Productivity

If the system maintains complete client-roaming records for all clients, then all roaming services can be immediately provided, but data storage and processing overhead increases

Engineering Contradiction:
Improveroaming service delivery speedVSAvoiddata storage requirements
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The system performs preliminary determination of whether a client requires roaming services before maintaining detailed roaming records. By pre-identifying roaming clients through detection modules that monitor client behavior and roaming indicators, the system prepares and maintains only the necessary roaming information in advance, avoiding unnecessary data storage for clients who will not require roaming services.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If the system processes and updates client records continuously for all clients, then client-state information is always current, but processing time and computational resources are wasted

Engineering Contradiction:
Improveclient information accuracyVSAvoiddata processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system dynamically adjusts its information maintenance and processing activities based on real-time detection of client roaming status. Rather than continuously processing all client records, the system activates detailed roaming information processing only when roaming conditions are detected, making the processing regime flexible and adaptive to actual client needs.

Inventive Principle:
Principle #15Dynamics

AI summary

A system for selectively handling client information in a network. In an illustrative embodiment, the system includes a first module adapted to determine whether a client will require roaming services or not. A second module, which communicates with the first module, maintains records of the client that are required only for roaming services only if the client will require roaming services as determined by the first module.
