Managed SIM Activity Notifications for Parent Device Monitoring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Parent devices are often unable to efficiently monitor and manage child devices, leading to issues such as disconnection from networks without notification, excess charges, and altered billing characteristics, due to inefficient communication of SIM status and activity.
Innovation Solution
Implementing a virtual bind system that monitors child device activity through a network operator, analyzing data from various sources to determine if activity warrants notifications to the parent device, including billing events, SIM deletions, and changes in device management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If parent devices directly monitor child device activity, then monitoring capability is improved, but device complexity and communication overhead increase
Solution Approach 1:
The network operator acts as an intermediary between the child device and parent device. The network operator monitors SIM status, billing events, and device activity, then selectively notifies the parent device only when significant events occur. This eliminates the need for continuous direct monitoring communication between parent and child devices, reducing communication overhead while maintaining reliable monitoring capability.
2Loss of time
If continuous monitoring of child device activity is implemented, then notification timeliness is improved, but energy consumption and system resources increase
Solution Approach 1:
Instead of continuous monitoring, the system uses event-triggered periodic checks where the network operator monitors for specific significant events (SIM status changes, billing events, device disconnections) and notifies the parent device only when these events occur. This approach maintains notification timeliness for critical events while significantly reducing energy consumption compared to continuous monitoring.
3Measurement precision
If detailed activity data is collected from child device, then billing accuracy is improved, but data privacy and security risks increase
Solution Approach 1:
The system extracts only the specific billing-relevant data elements needed for accurate charging (data usage volumes, call durations, service types) while leaving sensitive personal information and detailed activity patterns on the network operator's secure systems. This extraction approach maintains billing accuracy by capturing necessary metrics while minimizing data privacy and security risks by not transmitting or storing unnecessary sensitive information on parent devices.

AI summary
The document describes techniques, apparatuses, and systems for providing notifications on a managing device. A first device may include a first subscriber identity module (SIM) that is at least partially managed by a second device having a second SIM. Activity associated with the first SIM may be monitored to determine if any activity associated with the first SIM is worthy of notifying the second device. If it is determined that the activity is worthy of notifying the second device, a notification indicative of the activity associated with the first SIM is transmitted to the second device. In this way, a managing device may be notified of activity on a managed device.
