Emergency Node State Switching for Secure One-to-One Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in emergency response incidents are vulnerable to unauthorized access, posing a risk to personnel and equipment safety.
Innovation Solution
A first node and a wireless device are configured to operate in specific states, allowing a one-to-one connection only after a valid request, thereby preventing unauthorized access and ensuring secure communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the first node is configured to allow connections to wireless devices, then communication capability is improved, but security vulnerability increases
Solution Approach 1:
The first node dynamically changes its connection state between a first state (unable to initiate connections) and a second state (able to initiate one-to-one connections). This dynamic state change allows the system to adapt communication capability based on security requirements, enabling connections only when authorized while preventing unauthorized access at other times.
Solution Approach 2:
The system performs preliminary state verification before allowing connections. The wireless device must first request connection information about the first node's state, and only if the node is in the appropriate second state can a connection be initiated. This preliminary check prevents unauthorized devices from accessing the node.
2Object-affected harmful factors
If the first node maintains strict security controls, then unauthorized access is prevented, but connection establishment complexity increases
Solution Approach 1:
The first node autonomously manages its own connection state and authorization decisions. When a wireless device requests connection information, the node itself verifies whether it is in the appropriate state to allow connections and responds accordingly. This self-service approach simplifies the overall system architecture by eliminating the need for complex external authentication mechanisms.
3Object-affected harmful factors
If the first node operates in a restricted state, then security is improved, but communication functionality is reduced
Solution Approach 1:
The first node transitions between restricted first state and functional second state based on authorization requirements. When authorized, the node enables one-to-one connections with specific wireless devices while maintaining security controls. This dynamic adaptation allows the system to provide full communication functionality only when security conditions are met, while restricting functionality otherwise.

AI summary
There is provided a method for handling connection requests in a network. The method is performed by a first node of the network. The first node is deployed at an emergency response incident. The method comprises, in response to obtaining a first input, changing a state of the first node from a first state to a second state. The method comprises receiving, from a first wireless device deployed at the emergency response incident, a first request for information indicative of the state of the first node. The method comprises initiating transmission of a first response towards the first wireless device. The method comprises, in response to receiving a second request from the first wireless device, initiating a one-to-one connection to the first wireless device, and changing the state of the first node from the second state to the first state.
