Master Subscription Mechanism for IoT Group Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The explosion of IoT devices leads to increased network traffic, latency, and efficiency issues due to individual device subscriptions and communication fragmentation across different networks, making it difficult for MTC servers to communicate effectively without adaption layers.
Innovation Solution
A master subscription mechanism is introduced, utilizing existing telecom core network infrastructure, where a single master subscription manages a group of IoT devices, reducing network traffic and burden on the Home Subscriber Server (HSS), and assigning a unique IMSI to the group rather than individual devices, enabling efficient communication and message delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual device subscriptions are used for each IoT device, then each device can be managed independently, but network traffic increases and latency increases due to the large number of devices
Solution Approach 1:
The patent combines multiple individual device subscriptions into a single group subscription. The HSS creates one subscription record that represents a group of IoT devices, allowing the network to manage and communicate with multiple devices through a single subscription entry, thereby reducing network traffic and latency while maintaining the ability to address individual devices within the group.
2Ease of operation
If individual subscriptions are created for each IoT device, then device-specific management is enabled, but the burden on the Home Subscriber Server increases
Solution Approach 1:
The patent merges multiple device subscription records into a single group subscription record in the HSS. This consolidation reduces the number of subscription entries the HSS must maintain and process, thereby reducing the server's management burden and complexity while still enabling device-specific operations through the group context.
Solution Approach 2:
The group subscription serves multiple functions: it manages a collection of devices, enables group-level policies, and provides a unified interface for network operations. This multi-functional approach allows the HSS to handle device management more efficiently without sacrificing device-specific control capabilities.
3Reliability
If a large number of unique IMSI values are assigned to individual IoT devices, then each device has a unique identifier, but IMSI values are depleted and difficult to manage
Solution Approach 1:
The patent assigns a single unique IMSI value to represent a group of IoT devices rather than assigning separate IMSI values to each device. This grouping approach conserves the limited pool of IMSI values while maintaining reliable unique identification at the group level, and devices within the group can be distinguished through other identifiers or context.

AI summary
Examples herein relate to development of a master subscription at a home subscriber server (HSS). Examples disclose based on an activation from a gateway, the development of the master subscription at the HSS. The master subscription is exclusive to a group of Internet of Things (IoT) devices tethered to the gateway. Based on the master subscription developed at the HSS, a message, intended for a target IoT device among the group of IoT devices tether to the gateway, is transmitted to the gateway.
