IoT Profiles for RAN Event-Based Charging and Resource Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cellular wireless networks face challenges in managing and optimizing the impact of IoT devices on the Radio Access Network (RAN) due to their frequent attachment and detachment, which can lead to inefficient resource usage and increased burdens on network resources.
Innovation Solution
Implementing IoT profiles that specify resource limits and policy responses based on RAN events, such as charging rules and network access controls, to effectively manage and charge IoT devices, with the Machine Interface Network Treatment (MINT) component aggregating resource statistics and enforcing these policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IoT devices frequently attach and detach from the RAN, then network coverage and accessibility are improved, but the burden on RAN resources increases and resource usage efficiency deteriorates
Solution Approach 1:
The patent introduces event-based charging parameters that track and charge for specific RAN events (attach, detach, service requests). By changing the charging model from data-volume based to event-based, the system can account for the frequent attach/detach behavior of IoT devices while creating economic incentives to reduce unnecessary RAN events, thus resolving the contradiction between maintaining accessibility and reducing resource consumption
Solution Approach 2:
The patent implements a feedback mechanism where the charging system monitors RAN events and provides billing feedback to IoT devices or operators. This feedback loop allows the system to respond to frequent attach/detach patterns by applying appropriate charges, which can influence device behavior to reduce unnecessary RAN events while maintaining necessary connectivity, thereby balancing accessibility with resource efficiency
2Quantity of substance
If IoT devices transmit small data infrequently, then bandwidth requirements are reduced, but the frequency of attach/detach events increases RAN signaling overhead
Solution Approach 1:
The patent segments the charging process into distinct event-based components (attach events, detach events, service request events). By segmenting the charging model to track each RAN event separately, the system can accurately account for signaling overhead independently of data volume, allowing for precise billing that reflects the actual RAN burden caused by frequent attach/detach cycles of low-bandwidth IoT devices
3Productivity
If resource limits and policy responses are enforced based on RAN events, then network performance is optimized, but system complexity increases due to profile management
Solution Approach 1:
The patent creates a universal IoT profile framework that can be applied across different IoT device types and scenarios. The profile structure is designed to be multi-functional, handling various RAN events (attach, detach, service requests) and triggering different policy responses based on a standardized template. This universality reduces the need for custom solutions for each device type, managing the complexity through standardization while maintaining the ability to optimize network performance across diverse IoT deployments

AI summary
RAN events associated with IoT devices may be monitored and tracked. Profiles may be defined for different IoT devices. The profiles may specify resource limits for the IoT devices, including resource limits based on the RAN events. The IoT profiles may also define policy responses based on the occurrence of the RAN events. The policy responses may include charging rules, network access control rules, or other rules based on the resource usage of the IoT devices.
