Solution Overview

Problem

User devices often experience conflicts when trying to selectively connect to one available network service over another, requiring manual configuration to access desired services.

Innovation Solution

The system filters access to network services by transmitting identifiers associated with specific services and using filter elements to inhibit access to undesired services, ensuring that user devices connect only to subscribed services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual configuration is used to selectively connect user devices to network services, then access control precision is improved, but device complexity and user operation difficulty increase

Engineering Contradiction:
Improveaccess control precisionVSAvoidconfiguration complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The network device automatically performs service filtering and access control without requiring manual user configuration. The device receives filter elements, processes them to determine service accessibility, and automatically enforces the filtering rules, eliminating the need for users to manually configure access preferences while maintaining precise control over which services are accessible.

Inventive Principle:
Principle #25Self-service

2Ease of operation

If automatic service filtering is implemented, then ease of operation is improved, but device complexity increases

Engineering Contradiction:
Improveservice selection easeVSAvoidfilter processing complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The network device acts as an intermediary between user devices and network services, receiving filter elements that encode service accessibility rules. It processes these filter elements to determine which services should be accessible or blocked, and automatically enforces these rules without requiring users to understand or configure the underlying complexity. This mediator approach simplifies user interaction while managing the computational complexity internally.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Systems and methods for managing a network are disclosed. One method can comprise transmitting a first identifier associated with a first service. Access to the first service can be provided to a user device using the first identifier. A filter element associated with the user device can be received. Transmission of a second identifier associated with a second service can be filtered based on the filter element, wherein filtering transmission inhibits access of the user device to the second service.
