Assisted Emergency Call Session Establishment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in quickly and efficiently establishing emergency sessions, especially when one user is unable to initiate an emergency call due to limited communication capabilities or when terminals are served by different networks, leading to potential delays in providing emergency services.
Innovation Solution
The system allows a second terminal to transmit an indicator for emergency service, automatically establishing a call session between the first terminal and an emergency center without user intervention, enabling an assisted emergency session that can be initiated during ongoing calls or as a conference session, even if the terminals are served by different networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a user initiates an emergency call manually, then the emergency service can be requested, but the process is delayed when the user is unable to communicate effectively or when terminals are served by different networks
Solution Approach 1:
The system enables self-service emergency calling by automatically detecting emergency situations through sensors (accelerometer, gyroscope, microphone) and initiating emergency sessions without requiring user input. The terminal autonomously determines emergency status based on motion patterns, audio analysis, and call duration, then automatically establishes connection with emergency services.
Solution Approach 2:
The system performs preliminary actions by pre-configuring emergency session parameters, pre-identifying emergency contacts, and pre-establishing communication channels. Location information and terminal identifiers are prepared in advance, allowing immediate emergency session establishment when needed without delays for data collection or configuration.
2Productivity
If emergency sessions are handled by the visited network only, then local emergency response is improved, but assistance across different networks becomes difficult
Solution Approach 1:
The home network acts as an intermediary by receiving emergency session requests from the visited network, retrieving terminal subscription information and emergency contact data, then forwarding relevant information back to the visited network. This mediator approach enables seamless cross-network emergency assistance while maintaining local network autonomy and response speed.
Solution Approach 2:
The system implements universal emergency session handling that works across different network types and jurisdictions. The emergency session mechanism is designed to function independently of the specific network infrastructure, allowing terminals served by any network to receive emergency assistance through their local emergency services.
3Reliability
If authentication is required for emergency sessions, then security is maintained, but emergency calling becomes more complex and slower
Solution Approach 1:
The system extracts authentication requirements from the emergency session establishment process. By separating emergency sessions from normal authentication procedures, the system allows emergency calls to be established immediately without credential verification, while still maintaining security through network-level controls and post-session accountability mechanisms.
4Reliability
If the user must terminate existing calls to place emergency calls, then clear communication is ensured, but critical time is lost
Solution Approach 1:
The system merges emergency sessions with ongoing calls by establishing emergency sessions in parallel without requiring termination of existing communications. The terminal can maintain conversation with the original counterparty while simultaneously establishing emergency session connection, enabling continuous communication across multiple channels without time loss.

AI summary
There is provided a method in a communication system comprising a first terminal and an emergency center. The method comprises the steps of transmitting, by a second terminal, an indicator indicating that emergency service is required for the first terminal, and automatically establishing a call session between the first terminal and the emergency center in response to the indicator.
