Satellite Network Notification Scheduling for Traffic Burst Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Satellite communication networks face inefficiencies in message delivery due to devices missing notifications while in sleep mode or out of coverage, leading to data traffic bursts and increased network congestion, as well as user fees for unnecessary mailbox checks.
Innovation Solution
A method and system that schedules notifications to be sent to satellite communication devices during designated alert windows when they are likely to be listening, minimizing overlap with other devices and reducing unnecessary network traffic by confirming device availability and message acceptance before sending notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If satellite communication devices perform mailbox checks at the same time after exiting sleep mode, then devices can receive messages, but data traffic bursts cause network congestion and loss
Solution Approach 1:
The system performs preliminary actions by scheduling notifications in advance during alert windows when devices are listening, rather than waiting for devices to initiate mailbox checks. This proactive approach distributes network traffic evenly and prevents congestion bursts while ensuring messages are delivered reliably.
Solution Approach 2:
The system implements periodic alert windows at scheduled intervals when devices are known to be listening for notifications. This periodic structure replaces the chaotic simultaneous mailbox checks with organized, spaced-out notification deliveries, improving both reliability and network efficiency.
2Use of energy by moving object
If devices enter sleep mode to conserve battery power, then battery life is extended, but devices cannot receive messages or notifications
Solution Approach 1:
The system schedules notifications in advance during alert windows when devices are guaranteed to be listening. This preliminary scheduling ensures message delivery reliability without requiring devices to remain continuously powered on, allowing them to sleep between alert windows and conserve battery power.
Solution Approach 2:
The system introduces alert windows as an intermediary mechanism between sleep mode and message reception. During these scheduled windows, devices temporarily wake to listen for notifications, bridging the gap between power conservation needs and message delivery requirements without continuous power consumption.
3Reliability
If devices perform frequent mailbox checks to ensure message receipt, then message delivery is improved, but network congestion and user fees increase
Solution Approach 1:
The system performs preliminary notification scheduling during alert windows before devices need to check for messages. This ensures devices only activate when there are actual notifications to deliver, eliminating wasteful network resource consumption from empty mailbox checks while maintaining complete message delivery assurance.
Solution Approach 2:
The system uses feedback mechanisms where devices indicate their listening status and message acceptance to the network. The network gateway uses this feedback to determine whether to send notifications, preventing wasteful transmissions when devices are not listening or don't need messages, thus reducing network resource consumption while maintaining reliability.
Data Source
AI summary
A system and method for optimizing satellite network utilization is disclosed. The method includes delivering a message to a communication device in the satellite network where a confirmation is received from a satellite network gateway that a message is intended for the communication device, scheduling a notification for the communication device at a scheduled time, and at the scheduled time, instructing the satellite network gateway to send the notification to the communication device. The notification causes the communication device to request the message from the network gateway upon receipt of the notification by the communication device. Scheduling may be coordinated within an alert window time period of the communication device when it is listening for notifications. The start time of the alert window time period may be provided by an application gateway, that along with the communication device, receive network time data to remain synchronized.
