Dynamic Alert Message Flow Control in Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Public alert systems face challenges in efficiently managing the flow of alert messages during emergency events, leading to network congestion and increased delivery failures due to the accumulation of bulk messages in mobile networks, which existing systems are not adequately prepared to handle within short time frames.
Innovation Solution
A method and system that dynamically control the flow of alert messages by accessing location information and message handling capacity of network elements, adjusting the sending rate based on real-time delivery status, failure, and success rates to optimize message delivery without congesting the mobile network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If bulk alert messages are sent to millions of subscribers within a short time frame, then the delivery speed and urgency requirement are met, but network congestion occurs and delivery failure rate increases
Solution Approach 1:
The system dynamically adjusts the sending rate of alert messages based on real-time network conditions and message handling capacity of network elements. Instead of using a fixed high-speed sending approach, the system continuously monitors network status and adapts the transmission rate to optimize both delivery speed and success rate, resolving the contradiction between urgency and reliability.
Solution Approach 2:
The system implements feedback mechanisms by monitoring real-time delivery status, failure rates, and network element capacity. This feedback information is used to continuously adjust the sending rate, ensuring that messages are delivered as quickly as possible while maintaining high delivery success rates by avoiding network overload.
2Loss of time
If alert messages are sent at high volume to meet emergency timing requirements, then the urgency and time sensitivity are addressed, but network congestion and message accumulation occur
Solution Approach 1:
The system performs preliminary actions by pre-assessing the message handling capacity of network elements before initiating bulk message transmission. This advance preparation allows the system to plan the message flow to meet timing requirements while avoiding network overload, thus preventing congestion before it occurs.
Solution Approach 2:
The system dynamically controls the message sending rate based on real-time network conditions and capacity monitoring. This dynamic adjustment ensures that messages are delivered within the required time frame while adapting to the network's actual handling capacity, preventing message accumulation and congestion.
3Speed
If the sending rate is increased to deliver messages faster, then delivery speed improves, but delivery failure rate increases due to network overload
Solution Approach 1:
The system dynamically adjusts the sending rate based on real-time feedback from the network. Instead of maintaining a constantly high sending rate, the system modulates the transmission speed according to network conditions, achieving fast delivery when capacity is available while preventing overload that would cause failures.
Solution Approach 2:
The system uses feedback from real-time delivery status monitoring to adjust the sending rate. When delivery success rates decline due to network overload, the system automatically reduces the sending rate to restore reliability, thus resolving the contradiction between speed and success rate.

AI summary
A method and a system for sending alert messages are provided. The method includes accessing location information of a plurality of user mobile devices in a mobile network from a database. The method further includes accessing a message handling capacity information of each of a plurality of network elements in the mobile network. Furthermore, the method includes sending, through the plurality of network elements, an alert message to the plurality of user mobile devices based on the location information. Moreover, sending the alert message through a network element of the plurality of network elements includes at least controlling a sending rate of the alert message through to the network element based on a message handling capacity information of the network element and a real-time delivery status information of the alert message that are already sent through the network element.
