Group IoT Device Registration Reduces Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method of individually registering and managing millions of IoT devices in wireless telecommunication networks leads to significant network congestion, inefficient use of resources, and increased battery power consumption, as each device requires frequent communication checks, resulting in slower data rates and higher maintenance burdens.
Innovation Solution
Implementing a group-level registration and notification system where IoT devices are registered collectively, allowing organizations to specify events for which they want to receive notifications, such as exiting Power Saving Mode, thereby reducing unnecessary network communication and conserving battery power.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual registration and management method is used for each IoT device, then device-specific monitoring and control can be achieved, but network congestion and resource inefficiency occur due to frequent communication checks for millions of devices
Solution Approach 1:
The patent merges individual device registrations into group-level registrations. Multiple IoT devices are collectively registered with a single registration message that includes a group identifier, allowing the network to monitor and manage entire groups of devices simultaneously rather than individually, thus reducing network traffic while maintaining monitoring capability
Solution Approach 2:
The patent implements universal group-based notification mechanisms that can serve multiple devices across different applications and scenarios. A single notification subscription can cover entire categories of IoT devices (e.g., all temperature sensors, all smart meters), enabling one system to handle diverse device types through standardized group management
2Reliability
If frequent communication checks are performed for each IoT device, then device availability can be ensured, but battery power consumption increases significantly
Solution Approach 1:
The patent implements periodic group-level communication instead of continuous individual device checks. The network performs availability checks and sends notifications at scheduled intervals to groups of devices, allowing IoT devices to remain in low-power states between checks while still maintaining reliability through systematic periodic monitoring
Solution Approach 2:
The patent enables devices to self-manage their availability status within groups. When a device becomes available or unavailable, it autonomously updates its group registration status without requiring individual polling, reducing the communication overhead and energy consumption associated with active querying of each device
3Ease of operation
If individual device registration is implemented, then precise device management is achieved, but network traffic and maintenance burden increase significantly
Solution Approach 1:
The patent combines multiple individual registration operations into a single group registration message. Instead of sending separate registration requests for each IoT device, the system transmits one consolidated registration message containing group identifiers and device lists, dramatically reducing the volume of registration traffic while maintaining precise device-level management capabilities
Solution Approach 2:
The patent uses template-based group registration where a single registration message serves as a template that can be replicated and applied to multiple devices with similar characteristics. This copying mechanism allows rapid deployment of large numbers of devices using standardized group configurations, reducing the maintenance burden and traffic associated with custom individual registrations

AI summary
Techniques described herein may be used to enable a wireless telecommunication network to provide notification to external devices (such as application servers) regarding Internet-of-Things (IoT) devices attached to the network. A customer may create a notification subscription regarding a group of IoT devices attached to the network. The subscription may identify the IoT devices, the events for which the customer would like to be notified, and an application server that is to receive the notifications (e.g., the IoT devices becoming available to send and receive information), and the application server that is to receive the notifications. The network may monitor the group of IoT devices for the events included in the subscription and may notify the application server if/when the events occur. In response, the application server may communicate with the IoT devices via the network.
