Network Access Management for Malfunctioning End Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Misconfigured or malfunctioning end devices in Next Generation wireless networks, such as 5G NR, lead to inefficient use of network resources and difficulties in isolating and correcting their behavior, causing continuous attachment and detachment from the network.
Innovation Solution
A network access management service that identifies and manages misconfigured or malfunctioning end devices by preventing network attachment, detaching them if already attached, and reconfiguring or restricting their updates to correct the issues, utilizing control plane signaling and core network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If end devices are allowed continuous network access, then network service availability is maintained, but network resource waste increases due to malfunctioning devices
Solution Approach 1:
The network access management service performs preliminary identification of malfunctioning end devices before they can consume excessive network resources. By detecting devices with continuous attachment-detachment behavior patterns and preventing their network access in advance, the system avoids the waste of network resources while maintaining service availability for properly functioning devices
Solution Approach 2:
The system implements a feedback mechanism where the network access management service continuously monitors network access patterns, identifies malfunctioning devices based on their behavior, and dynamically adjusts access permissions. This feedback loop enables the network to respond to device performance issues in real-time, preventing resource waste from devices that exhibit continuous attachment and detachment
2Loss of energy
If network access is restricted for suspected malfunctioning devices, then network resource efficiency improves, but device functionality may be incorrectly limited
Solution Approach 1:
The network access management service applies partial restriction by targeting only specific malfunctioning behaviors (continuous attachment-detachment patterns) rather than imposing blanket restrictions on all devices. This selective approach ensures that only devices exhibiting problematic patterns are limited, while maintaining full access flexibility for devices that function normally
Solution Approach 2:
The system changes the parameter of network access permission dynamically based on device behavior characteristics. By monitoring attachment-detachment patterns and other behavioral parameters, the system adjusts access rights in real-time, restricting access only when malfunctioning patterns are detected and restoring full access when devices operate normally
3Stability of the object's composition
If malfunctioning devices are identified and managed, then network stability improves, but system complexity increases due to additional management functions
Solution Approach 1:
The network access management service integrates multiple functions into a single unified system: monitoring network access patterns, identifying malfunctioning devices, preventing unauthorized access, and managing device reconfiguration. This multi-functional approach consolidates what could be separate complex systems into one cohesive service, improving network stability without proportionally increasing overall system complexity
Solution Approach 2:
The system implements self-service capabilities where the network access management service automatically detects malfunctioning devices based on their behavior patterns and autonomously implements access restrictions or reconfiguration commands. This automation eliminates the need for manual intervention and complex management interfaces, achieving network stability through self-managing mechanisms

AI summary
A method, a device, and a non-transitory storage medium are described in which a network access management service is provided. The service may include modifying subscription data pertaining to an end device. The modification may include control data directed to remediating behavior of the end device. The service may provide the control data to the end device during a registration procedure or a deregistration procedure with the end device. The end device may execute a remedial procedure based on the control data. The service may prevent the registering of the end device to the core network. The service may deregister the end device from the core network when the end device may be registered.
