Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Wireless service providers face challenges in maintaining communication quality due to access point congestion, as existing systems do not consider access point capacity when authorizing new users, leading to potential poor call quality and customer dissatisfaction.

Innovation Solution

An access point management facility that utilizes both static and dynamic parameters to evaluate and manage access to an access point, ensuring a desired quality of service by limiting the number of connected devices and prioritizing traffic based on current and historical data.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If access point capacity is not considered when authorizing new users, then user authorization is simple and fast, but access point congestion occurs leading to poor call quality

Engineering Contradiction:

Improveuser authorization processVSAvoidcall quality

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary evaluation of access point capacity parameters (such as available bandwidth, current load, and quality of service metrics) before authorizing new users. The access point management facility assesses whether the access point can accommodate additional users while maintaining desired quality of service levels, preventing congestion before it occurs.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

An access point management facility is introduced as an intermediary between users and access points. This facility evaluates access point capacity parameters and makes authorization decisions, separating the authorization function from the access points themselves and enabling centralized capacity management.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If access point capacity is monitored and managed, then call quality is maintained, but system complexity increases

Engineering Contradiction:

Improvecall qualityVSAvoidaccess point management system

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The access point management facility performs multiple functions including evaluating access point capacity parameters, authorizing users, directing users to appropriate access points, and managing load distribution. By consolidating these functions in a single facility, the system avoids the complexity of implementing all these functions in each individual access point.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

Access points report their capacity parameters and current status to the management facility, and the facility automatically makes authorization and load balancing decisions based on these reports. The system operates autonomously using automated decision-making algorithms, reducing the need for manual intervention and complex control mechanisms.

Inventive Principle:

Principle #25Self-service

AI summary

An access point management facility manages use of an access point configured for IP-based communications in a telecommunications system. The facility allows for the establishment of one or more static and/or dynamic parameters for limiting use of the access point for IP-based communications. The facility monitors traffic on the access point and determines whether any requests for use of the access point complies with the parameters for limiting use. The facility then denies or redirects a request for use of the access point if otherwise permitting the request would not comply with the parameters for limiting use of the access point.
