Industrial Traffic Access Control Mechanism for 5G Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 5G core network struggles to accommodate high-speed ultra-wide band services due to difficulties in managing latency and reliability, particularly in scenarios requiring low latency and high reliability such as autonomous driving and factory automation.
Innovation Solution
An operation method for a terminal that involves receiving system information including access control-related information about industrial signaling and/or data from a base station, determining an access category based on access identities, performing a unified access control check, determining an RRC establishment or resumption cause, and transmitting an RRC message to the base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the existing 5G core network is used to support high-speed ultra-wide band services, then data transfer rate can be improved, but latency and reliability cannot be adequately managed
Solution Approach 1:
The patent segments industrial traffic from general mobile traffic by introducing a dedicated access control mechanism specifically for industrial signaling and data. This segmentation allows the network to handle industrial traffic with specialized parameters (latency, reliability) separate from general high-speed data traffic, resolving the contradiction between speed and reliability management.
Solution Approach 2:
The patent applies local quality by implementing access control parameters specifically tailored for industrial traffic characteristics. Instead of using uniform access control for all traffic types, the system applies localized access control rules with specific parameters (priority levels, latency requirements, reliability thresholds) to industrial traffic, enabling appropriate latency and reliability management for this specific traffic type while maintaining high-speed capabilities for other traffic.
2Device complexity
If access control is not implemented for industrial traffic, then network simplicity is maintained, but congestion conditions worsen and resource waste increases
Solution Approach 1:
The patent implements preliminary action by establishing access control rules and parameters before industrial traffic congestion occurs. The base station pre-configures access control information including priority levels, latency requirements, and resource allocation rules for industrial traffic. When industrial signaling or data needs to access the network, the terminal performs preliminary access control checks against these pre-configured rules, preventing congestion before it occurs and improving overall network productivity without adding complex real-time control mechanisms.
3Productivity
If unified access control check is performed for industrial signaling, then access control efficiency is improved, but signaling overhead increases
Solution Approach 1:
The patent applies parameter changes by modifying access control parameters specifically for industrial traffic rather than changing the fundamental access control structure. The system introduces parameters such as access category indicators, priority levels, and latency requirements that are appended to or integrated with existing access control messages. This approach improves access control efficiency for industrial signaling while minimizing signaling overhead by reusing existing message formats and only adding necessary industrial-specific parameters.

AI summary
Disclosed is an operation method of a terminal. The operation method may comprise the steps of: receiving system information including access control-related information about industrial signaling and/or data; determining an access identity and an access category when originating industrial signaling or data is generated; performing a test for unified access control on the basis of the access identity, the access category, and the access control-related information; determining the cause of radio resource control (RRC) establishment or RRC resumption on the basis of the access category if the test is passed; and transmitting an RRC message including the determined cause of RRC establishment or RRC resumption.
