Wireless Roaming Traffic Control for Low-Data IoT Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of IoT devices requiring global connectivity through roaming poses challenges for mobile network operators, leading to signaling storms, network breakdowns, and financial losses due to low-data usage devices, as existing methods to manage these devices are either ineffective or detrimental to regular network operations.
Innovation Solution
A method for traffic management in wireless networks that identifies and blocks communication between low-data usage IoT devices and their home networks by using parameters like IMSI, IMEI, MSISDN, and data consumption patterns, and prevents communication through GTP firewalls, thereby reducing signaling and network load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile network operators allow permanent roaming for IoT devices, then global connectivity is achieved, but network stability deteriorates due to signaling storms from low data usage devices
Solution Approach 1:
The patent applies parameter changes by monitoring multiple parameters (data consumption, network connection duration, ratio of data consumption to connection duration) and adjusting network access rights based on threshold values. When parameters indicate suspicious behavior patterns, the system changes the access state from full roaming rights to restricted or blocked access, thereby resolving the contradiction between providing global connectivity and maintaining network stability.
Solution Approach 2:
The patent implements feedback mechanisms where the network operator's system continuously monitors traffic parameters from roaming devices and adjusts access rights based on observed behavior patterns. The system feeds back control decisions to the network elements (MME, HSS, PCRF) to dynamically manage roaming rights, preventing signaling storms while maintaining legitimate connectivity.
2Reliability
If network operators restrict access to roaming devices, then network stability is maintained, but device connectivity is reduced
Solution Approach 1:
The patent applies local quality by differentiating treatment based on device characteristics and behavior patterns. Instead of uniform blocking, the system identifies specific devices exhibiting suspicious patterns (low data consumption combined with long connection duration) and applies restricted access only to those devices, while maintaining full connectivity for legitimate roaming devices. This localized differentiation resolves the contradiction between network stability and device connectivity.
3Adaptability or versatility
If existing restriction methods are used to block roaming devices, then access is reduced, but signaling storms worsen due to ineffective blocking
Solution Approach 1:
The patent applies preliminary action by proactively identifying devices with suspicious behavior patterns before they can cause significant signaling storms. The system monitors parameters continuously and takes preventive blocking action when threshold violations occur, rather than reacting after storms have begun. This preliminary identification and action prevents the harmful effect of signaling storms while maintaining effective access control.
