Emergency Call Postfix Encoding for Silent Mode and Automated Alarm Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current emergency call systems are inadequate for communicating essential information, particularly for individuals with disabilities, automated alarms, and situations where voice communication is not feasible, as they rely on voice interaction and separate database storage related to phone numbers rather than users or usage.
Innovation Solution
The system enhances emergency calls by adding a postfix with emergency information to the dialled number, which is stored in a special parameter field and displayed to the emergency operator, allowing for automatic SMS transmission and phone mode adjustments (silent or disabled) to facilitate communication without voice, and distinguishes between human and automated calls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice communication is used between user and emergency operator, then information can be communicated orally, but it is cumbersome for disabled people and not feasible in stress situations or when hiding from burglars
Solution Approach 1:
The emergency number is segmented by adding a postfix with additional digits that encode specific emergency information (such as silent mode, disabled mode, automated alarm). This allows the transmission of multiple pieces of information through a structured number sequence rather than requiring verbal communication.
Solution Approach 2:
The patent introduces an intermediary processing system (network entry node, emergency centre) that automatically interprets the postfix digits and converts them into actionable information for the emergency operator, eliminating the need for direct voice communication while ensuring reliable information transmission.
2Loss of information
If emergency information is stored in a separate database related to phone number, then location information can be retrieved, but information about user capabilities (speech/hearing disability) is not available when not the regular extension number
Solution Approach 1:
The user pre-configures their phone with specific postfix digit sequences that represent their emergency information needs (such as disabled mode, silent mode, automated alarm type). This preliminary configuration ensures that the correct information is automatically transmitted without requiring database lookups based on phone number.
Solution Approach 2:
The system changes the parameter representation from static database entries tied to phone numbers to dynamic postfix digit sequences that can be universally applied across different phones and users, making the system adaptable to any user situation.
3Productivity
If automated alarm systems place emergency calls, then emergency notification is provided, but no voice communication is possible and the system cannot distinguish between human and automated calls
Solution Approach 1:
The postfix digits are segmented into specific ranges that indicate the type of caller (human vs. automated alarm system). This segmentation allows the emergency centre to quickly identify the call origin and appropriate response protocol without requiring voice communication or losing critical information.
Data Source
AI summary
A method and system, for adding emergency information to an emergency call, network transport of the emergency information and display to an emergency center operator. Emergency information may comprise; position indication, ability to voice answer, indication of accompanying SMS, automated alarm etc. and is added as postfix to the emergency number by the phone as shown in FIG. 3. The network entry node takes care of separation of dialled emergency number and emergency information, to enable normal set-up of the emergency call connection trough the network to the emergency center where the emergency information is presented to the emergency operator.
