Push Notification Self-Notification Avoidance via GUID Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In push notification systems, endpoint devices with shared identifiers receive unnecessary updates, leading to self-notification, increased wake-ups, synchronization, radio connection time, and battery power consumption.
Innovation Solution
A method and system that utilize a server to identify globally unique identifiers within notifications, preventing the originating device with the shared identifier from receiving updates, and pushing notifications only to devices with the shared identifier but not the globally unique identifier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If push notifications are sent to all endpoint devices with a shared identifier, then notification delivery accuracy is improved, but self-notification waste increases
Solution Approach 1:
The patent extracts the originating device from the notification distribution list by identifying its GUID in the notification payload. The server compares the GUID against device identifiers and excludes the originating device from receiving its own notification, thereby eliminating self-notification waste while maintaining accurate delivery to all other intended recipients.
Solution Approach 2:
The notification system incorporates feedback by including the originating device's GUID within the notification payload itself. This self-identifying information enables the server to recognize and filter out the originating device, creating a feedback mechanism that prevents energy-wasting self-notifications while preserving reliable delivery to other devices.
2Reliability
If push notifications are sent to all endpoint devices with a shared identifier, then notification completeness is improved, but synchronization overhead increases
Solution Approach 1:
The server extracts and identifies the originating device using the GUID contained in the notification. By removing the originating device from the notification distribution list, the system completes notifications to all necessary devices without redundant synchronization operations, thereby reducing overall synchronization overhead and time loss.
Solution Approach 2:
Instead of sending notifications to all devices with shared identifiers (excessive action), the system applies partial action by selectively excluding the originating device. This optimized approach maintains notification completeness for all affected devices while avoiding unnecessary synchronization cycles that would waste time.
3Productivity
If push notifications are sent to all endpoint devices with a shared identifier, then update propagation is improved, but radio connection time increases
Solution Approach 1:
The notification system extracts the originating device identifier from the GUID in the notification payload and uses it to filter out the originating device from the distribution list. This ensures rapid update propagation to all necessary devices while reducing radio connection time by eliminating redundant communication with the originating device.
Solution Approach 2:
The system applies partial action by sending notifications only to devices that need them (all devices with the shared identifier except the originating device). This optimized approach maintains fast update propagation while avoiding excessive radio connection time that would result from notifying the originating device of its own updates.

AI summary
A method for self-notification avoidance in a push notification system is provided. The method includes receiving, at a server configured to provide a push notification service, a notification from one of a plurality of endpoint devices to be pushed to the plurality of endpoint devices, wherein the plurality of endpoint devices has a shared identifier, and wherein the one of the plurality of endpoint devices has a globally unique identifier (GUID). The method includes identifying, at the server, the globally unique identifier in the notification and pushing the notification from the server to each of the plurality of endpoint devices having the shared identifier except the one of the plurality of endpoint devices that has the globally unique identifier.
