5G Access Control for Exception Data Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, there is a lack of effective methods for determining and managing access categories, leading to arbitrary high-priority access by terminals, which increases system load and can cause congestion.
Innovation Solution
A method for User Equipment (UE) and network nodes to perform access control by obtaining information related to exception data, determining the appropriate access category, performing an access control check, and allowing the transmission of exception data if access is permitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If terminals arbitrarily use high-priority access categories, then access speed is improved, but system load increases and congestion occurs
Solution Approach 1:
The patent changes the access category parameter dynamically based on data characteristics. Instead of using fixed high-priority access categories arbitrarily, the system determines the appropriate access category by analyzing data characteristics (exception data identification), thereby controlling system load while maintaining necessary access speeds for critical data.
2Reliability
If access control checks are performed for all data, then system stability is improved, but transmission delay increases
Solution Approach 1:
The patent extracts exception data from general data traffic and applies different access control rules. By identifying and separating exception data that requires strict access control, the system can perform comprehensive checks only on necessary data while allowing faster transmission for other data, thereby reducing overall transmission delay while maintaining system stability.
Solution Approach 2:
The patent segments data into different categories (exception data and non-exception data) and applies different access control procedures to each segment. This segmentation allows the system to perform detailed access control checks only where necessary, reducing unnecessary delays for routine data transmission while maintaining reliability for critical exception data.
3Speed
If exception data is prioritized in transmission, then critical data delivery is improved, but resource allocation complexity increases
Solution Approach 1:
The patent uses parameter changes (data characteristic analysis) to automatically determine priority levels. Instead of complex manual resource allocation, the system dynamically adjusts access category parameters based on identified data characteristics, simplifying the resource allocation process while ensuring exception data receives appropriate priority and faster delivery.

AI summary
A disclosure of the present specification provides a method for performing, by a UE, communication associated with access control. The method may comprise the steps of: acquiring information associated with exception data; determining an access category of an access attempt for the exception data, on the basis of the information associated with the exception data; performing an access control check on the basis of the determined access category; and, when access is allowed according to the access control check, transmitting the exception data.
