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 implement methods to manage connection states, allowing authorized one-to-one connections by changing states based on input requests, preventing unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If telemetry techniques are adopted to enhance communication between personnel, then communication capability and situational awareness are improved, but security vulnerability to unauthorized access increases
Solution Approach 1:
The system performs preliminary authentication and authorization actions before allowing any communication. The first node authenticates the second node and establishes authorized communication only after verification, preventing unauthorized access before it can occur rather than attempting to detect or respond to intrusions after they happen.
Solution Approach 2:
The first node acts as an intermediary between the second node (wireless device) and the emergency response network. It mediates all communication by first verifying the second node's identity and authorization status, then controlling whether communication is permitted. This intermediary layer blocks unauthorized devices from directly accessing the network.
2Reliability
If state management mechanism is implemented to control connection states, then security is improved, but device complexity increases
Solution Approach 1:
The security mechanism is segmented into distinct state categories (first state: unauthorized, second state: authorized). Each state has specific permitted operations defined separately, making the complex security logic more manageable and easier to implement. The segmentation allows the system to transition between clear-defined states rather than managing a continuous spectrum of permission levels.
Solution Approach 2:
The system dynamically transitions between discrete states based on authentication results. The first node changes from the first state (unable to initiate connection) to the second state (able to initiate connection) based on the authentication outcome. This dynamic state management provides flexibility while maintaining clarity, as each state has well-defined characteristics and transition conditions.
3Reliability
If one-to-one connection is established between first node and second node, then communication reliability is improved, but connectivity flexibility is reduced
Solution Approach 1:
The patent applies local quality by establishing dedicated one-to-one connections between specific pairs of nodes (first node and second node) rather than allowing arbitrary multi-point connections. Each authorized connection has dedicated resources and parameters optimized for that specific pair, improving reliability. The system maintains this localized approach while still allowing multiple such dedicated connections to coexist, balancing reliability with flexibility.

AI summary
There is provided a method for handling connection requests in a network. The method may be performed by a first node of the network. The first node may be deployed at an emergency response incident. The method may comprise, in response to obtaining a first input, changing a state of the first node from a first state to a second state. The method may comprise 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 may comprise initiating transmission of a first response towards the first wireless device. The method may comprise, 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.
