Solution Overview

Problem

Conventional systems for changing network behavior require manual administrator intervention, leading to static policies and potential security risks due to lack of dynamic adaptation based on user presence information.

Innovation Solution

A system and method that detects presence indicators to form an electronic persistent presence (EPP), dynamically changing network behavior by switching between user policies based on presence information, enhancing security and adaptability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual configuration by administrator is used to change network policy, then device complexity is reduced and ease of operation is improved, but adaptability deteriorates and productivity decreases due to static policies

Engineering Contradiction:
Improvepolicy adaptabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system automatically detects presence indicators and forms electronic persistent presences without requiring administrator intervention. The presence detection system autonomously monitors user presence and triggers policy changes based on predefined rules, enabling the network to self-adjust without manual configuration.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system changes network behavior by switching between different user policies based on detected presence information. When presence indicators are detected, the system transitions from a static policy state to a dynamic policy state, adjusting network parameters such as access rights and resource allocation in real-time.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If static user policy is maintained, then device complexity is reduced and ease of operation is improved, but security deteriorates due to lack of dynamic adaptation

Engineering Contradiction:
Improvenetwork securityVSAvoidpolicy management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system continuously monitors presence indicators and uses this feedback to dynamically adjust user policies. When presence information changes, the system receives feedback and automatically updates access controls, ensuring security is maintained without requiring complex manual policy management.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The presence detection system autonomously manages security policies by automatically detecting when users are present or absent and triggering appropriate policy changes. This self-service approach maintains security without requiring administrator intervention or complex manual policy updates.

Inventive Principle:
Principle #25Self-service

3Productivity

If manual policy change is required, then ease of operation is improved and device complexity is reduced, but productivity decreases due to inability to respond to real-time presence changes

Engineering Contradiction:
Improvenetwork response speedVSAvoidoperation simplicity
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The system continuously monitors presence indicators and maintains constant readiness to update policies. The presence detection operates continuously without interruption, ensuring that network behavior is always current and can respond immediately to presence changes without requiring manual intervention.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The system automatically detects presence changes and triggers policy updates without requiring operator involvement. This self-service mechanism eliminates the delay between presence detection and policy response, achieving real-time network adaptation while maintaining operational simplicity.

Inventive Principle:
Principle #25Self-service

AI summary

A system and method for changing network behavior based on presence information includes detecting one or more presence indicators. The one or more presence indicators indicate presence information. An electronic persistent presence (EPP) is formed based on the one or more presence indicators. It is determined whether to change the network behavior from a first user policy to a second user policy according to the EPP. The second user policy associated with the EPP is implemented according to a determination that the network behavior is to be changed.
