Solution Overview

Problem

In emergency situations, private networks of facilities often remain inaccessible to first responders, despite containing critical information and access capabilities that could aid in addressing the emergency, such as security footage and door unlocking.

Innovation Solution

A public safety system that provides temporary access to private networks for first responders by sending configuration credentials to their user devices, allowing them to access facility information and interact with the network, using wireless technologies like 4G, LTE, Wi-Fi, or 5G, and enabling push-to-talk services and targeted alerts.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If private networks remain closed to maintain security and privacy, then network security and user privacy are protected, but first responders cannot access critical information during emergencies

Engineering Contradiction:
Improvenetwork securityVSAvoidemergency access capability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic network access control by transitioning the private network from a closed state during normal operations to an open state during emergencies. The system dynamically adjusts network accessibility based on emergency status, allowing first responders to access the network when needed while maintaining security during non-emergency periods. This is achieved through emergency status detection and automatic network state transitions.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system changes the access control parameters of the private network based on emergency conditions. During emergencies, the network parameters are modified to permit first responder access, while during normal operations, the parameters maintain restricted access. This parameter change approach allows the same network to serve different security requirements under different conditions.

Inventive Principle:
Principle #35Parameter changes

2Ease of operation

If first responders are granted access to private networks during emergencies, then access to critical facility information is enabled, but network security and privacy protection may be compromised

Engineering Contradiction:
Improvefirst responder accessVSAvoidsecurity risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces an intermediary access control mechanism that mediates between first responders and the private network. Rather than directly granting or denying access, the system uses an intermediate layer that verifies emergency status and authorizes access appropriately. This intermediary approach enables first responder access during emergencies while maintaining security controls, as the intermediary validates the legitimacy of access requests before permitting network entry.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If private networks are opened to first responders, then emergency response efficiency is improved, but network complexity and access management become more difficult

Engineering Contradiction:
Improveemergency response efficiencyVSAvoidaccess management complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-configuring the system with first responder credentials and emergency access protocols before emergencies occur. The network is pre-prepared to recognize and authorize first responders when emergencies are detected, eliminating the need for complex real-time access management decisions. This preliminary setup simplifies access management during actual emergencies, as the system automatically recognizes authorized users and grants access based on pre-established rules.

Inventive Principle:
Principle #10Preliminary action
