Emergency Call Network Event Detection and Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Emergency call networks become overloaded during events, leading to redundant calls and inefficient utilization of resources, causing urgent calls to be neglected and wasting network bandwidth.
Innovation Solution
Implementing a system that detects emergency events through call analysis and broadcasts notifications to users within a specific area, prioritizing non-emergency calls and reducing redundant emergency calls by identifying the disaster area based on call patterns and external information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If emergency call networks accept all incoming calls during events, then all callers can be served, but network resources become overloaded and redundant calls waste bandwidth
Solution Approach 1:
The system performs preliminary detection of emergency events by analyzing call patterns before the network becomes overloaded. By detecting clusters of emergency calls from specific geographic areas, the system proactively identifies events and broadcasts notifications to potential callers, preventing redundant calls from being placed and conserving network resources before overload occurs.
Solution Approach 2:
The system implements a feedback loop where emergency calls are analyzed to detect events, and the detected event information is broadcast back to users in the affected area. This feedback mechanism informs potential callers that an emergency has already been detected and is being handled, reducing the likelihood of additional redundant calls and optimizing network resource utilization.
2Ease of operation
If emergency operators answer all incoming calls, then all callers receive attention, but operator efficiency decreases due to numerous redundant calls
Solution Approach 1:
The system performs preliminary detection and broadcasting of emergency events before operators need to handle individual calls. By automatically detecting event patterns and notifying users in advance, the system prepares the situation so that operators receive fewer redundant calls, allowing them to focus on unique, non-redundant emergency situations and improving their productivity.
Solution Approach 2:
The system introduces an intermediary automated detection and notification mechanism between callers and operators. This intermediary analyzes call patterns, detects events, and broadcasts information to users, filtering out redundant calls before they reach operators. This allows operators to maintain accessibility while improving efficiency by handling only necessary calls.
3Loss of information
If the system broadcasts notifications to all users, then all users receive emergency information, but network resources are consumed by the broadcast itself
Solution Approach 1:
The system applies local quality by broadcasting emergency notifications only to users within the specific geographic area where an event was detected. By analyzing the geographic distribution of emergency calls and limiting broadcasts to affected regions, the system ensures comprehensive information dissemination to relevant users while minimizing unnecessary network resource consumption from broadcasting to unrelated areas.
Data Source
AI summary
A server device may be configured to receive information regarding calls that have been placed; detect, based on the information regarding the calls that have been placed, an occurrence of an event; determine a set of base stations that are associated with the event; and broadcast, via the set of base stations, a message regarding the event.
