Emergency Alert Notification via Network Indicator Bits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing broadcast technologies for emergency alert notifications on portable devices require continuous monitoring, which significantly impacts battery life and network bandwidth, and users are not adequately informed when emergency alerts are broadcast.
Innovation Solution
A mechanism that notifies users of emergency alerts via networked portable devices without continuous monitoring, using an emergency alert indicator bit on control channels or SMS messages, allowing devices to automatically receive and display alert information without user intervention, utilizing telephony radio networks and broadcast processors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If continuous monitoring of broadcast channels is implemented to detect emergency alerts, then users are informed of emergency alerts, but battery life is significantly reduced
Solution Approach 1:
The system transitions from continuous monitoring to periodic action by using event-triggered notifications. The network monitors broadcast channels periodically and sends alert notifications only when emergency alerts are detected, rather than requiring the handset to continuously monitor. This resolves the contradiction by maintaining notification reliability through network-side periodic monitoring while eliminating the energy consumption of continuous handset monitoring.
Solution Approach 2:
The network infrastructure acts as an intermediary between the broadcast channel and the user's handset. Instead of the handset directly and continuously monitoring broadcast channels, the network receives and processes emergency alert information, then notifies the handset only when relevant alerts are detected. This intermediary approach maintains notification reliability while eliminating the need for continuous handset monitoring and associated battery consumption.
2Reliability
If continuous monitoring of broadcast channels is implemented to detect emergency alerts, then users are informed of emergency alerts, but network bandwidth is unnecessarily consumed
Solution Approach 1:
The system implements periodic action at the network level by monitoring broadcast channels at intervals and sending notifications only when emergency alerts are detected. This eliminates the need for continuous monitoring and associated network bandwidth consumption, while maintaining reliable notification delivery through event-triggered alert messages.
Solution Approach 2:
The system extracts only the essential notification function from continuous monitoring. Instead of maintaining constant communication channels between the handset and broadcast system, the network extracts and delivers only the critical alert information when emergencies are detected, eliminating unnecessary network bandwidth consumption while preserving notification reliability.
3Loss of energy
If users manually tune to broadcast channels to check for emergency alerts, then network bandwidth and battery life are conserved, but users are not promptly informed of emergency alerts
Solution Approach 1:
The system performs preliminary action by having the network pre-monitor broadcast channels and prepare alert notifications before users need the information. When emergency alerts are detected, the network has already processed the information and can immediately notify users, eliminating the time delay associated with manual channel tuning while avoiding continuous monitoring of the handset.
Solution Approach 2:
The network performs self-service by autonomously monitoring broadcast channels and generating alert notifications without requiring user action. The system automatically detects emergency alerts and pushes notifications to handsets, eliminating both the time loss from manual tuning and the energy consumption from continuous handset monitoring, as the network handles the monitoring task independently.
Data Source
AI summary
Systems and methods for providing alerts to end users of networked enabled portable devices are provided so that the end users are made aware when broadcast emergency alerts are issued. In various embodiments, a portable device is enabled to receive information about an emergency alert broadcast of which the user should be aware, e.g., from the EAS, and to notify the user of the emergency alert. The user can be automatically taken to the emergency alert information by having the portable device automatically tune to the emergency broadcast information, the user can optionally retrieve the emergency information by tuning to the emergency broadcast channel, and/or the user can otherwise be presented with a reference to the emergency data, such as a link to the information.
