Geographic SMS Alert Distribution via Dynamic Cell Site Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Subscribers roaming outside a specified geographic area, such as on vacation, cannot receive emergency alert notifications via SMS, as existing systems do not practically provide alerts to all possible geographic areas.
Innovation Solution
Implementing a system where a subscriber's mobile device registers with cell sites in various locations, updating their profile to receive SMS alerts based on current location, and using Emergency Alert Servers to determine and deliver alerts to relevant cell sites within the subscriber's geographic area, either statically or dynamically defined.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If alert messages are provided to all possible geographic areas, then roaming subscribers can receive emergency alerts, but system complexity and resource consumption increase significantly
Solution Approach 1:
The system performs preliminary actions by establishing subscriber profiles in advance that include preferred communication methods (SMS, email, voice) and alert preferences. When an emergency alert is issued, the system queries these pre-established profiles to determine the appropriate delivery method, avoiding the need to analyze subscriber preferences in real-time during alert distribution.
Solution Approach 2:
The patent introduces an intermediary alert distribution system that acts as a mediator between the emergency alert authority and subscribers. This intermediary system queries subscriber profiles, determines appropriate communication methods, and routes alerts accordingly. This intermediary layer simplifies the overall system by centralizing the decision-making logic for alert distribution.
2Loss of energy
If alert messages are provided only to specified geographic areas, then system resources are conserved, but roaming subscribers cannot receive emergency alerts
Solution Approach 1:
The system dynamically adapts alert distribution based on subscriber location and preferences. Instead of static geographic area-based distribution, the system queries subscriber profiles to determine current location and preferred communication methods, then dynamically routes alerts accordingly. This allows efficient resource usage while maintaining reliable delivery to roaming subscribers.
Solution Approach 2:
The patent changes the parameter for alert distribution from fixed geographic area to dynamic subscriber profile-based routing. By querying subscriber profiles that include location information and communication preferences, the system adjusts the distribution parameters to match actual subscriber needs, reducing wasted resources while improving delivery reliability.
3Measurement precision
If subscriber profiles are analyzed in real-time for each alert, then accurate delivery is achieved, but processing time increases
Solution Approach 1:
Subscriber profiles are established and maintained in advance with all necessary information including communication preferences, location data, and alert subscriptions. When an alert needs to be distributed, the system simply queries this pre-prepared information rather than analyzing subscriber data in real-time, significantly reducing processing time while maintaining accuracy.
4Area of stationary object
If SMS alerts are sent to multiple locations, then coverage is improved, but message volume and network load increase
Solution Approach 1:
The system changes the parameter for alert distribution from blanket geographic area coverage to targeted subscriber-based routing. By querying subscriber profiles to determine current location and communication preferences, the system sends alerts only to relevant subscribers through their preferred channels, reducing overall message volume while improving effective coverage.
Data Source
AI summary
SMS alert messages are provided to the current geographic location of a registered SMS subscriber. When an SMS subscriber's mobile device is registered, the subscriber's profile is analyzed to determine if the subscriber wants to receive alert messages via SMS. If so, cell sites associated with the current location of the subscriber are utilized to provide alert messages. As the subscriber register's his/her mobile device in other geographic locations, the current location of the subscriber is updated.
