Unified Access Control for Next Generation Mobile Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next generation mobile communication systems face complexity and increased signaling due to different access barring mechanisms being implemented in both network and user equipment, leading to inefficiencies in congestion control.
Innovation Solution
A unified access control method is introduced, where user equipment receives system information including access category and barring parameters from the base station, allowing for integrated access barring checks in the access stratum layer, reducing unnecessary signaling and complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If different access barring mechanisms are implemented in each protocol layer to control congestion, then congestion control effectiveness is improved, but device complexity and signaling increase
Solution Approach 1:
The patent combines multiple access barring mechanisms from different protocol layers into a unified access control framework. Instead of implementing separate access barring functions at each layer, the invention merges them into a single unified mechanism that handles access control across all layers, thereby reducing device complexity while maintaining congestion control effectiveness
Solution Approach 2:
The unified access control mechanism serves multiple functions across different protocol layers simultaneously. A single access control function performs the roles previously distributed across multiple layer-specific mechanisms, enabling one system to handle diverse access control requirements without requiring separate implementations for each layer
2Adaptability or versatility
If individual access barring functions are implemented with different solutions at network and user equipment, then specific access requirements are satisfied, but signaling overhead increases
Solution Approach 1:
The unified access control mechanism provides a universal solution that satisfies multiple specific access requirements through a single framework. Instead of implementing separate signaling protocols for different access barring functions, the invention uses one universal access control mechanism that adapts to various access scenarios, thereby reducing signaling overhead while maintaining adaptability
3Reliability
If multiple separate access barring mechanisms are maintained, then comprehensive congestion control is achieved, but radio resource efficiency decreases
Solution Approach 1:
The patent merges multiple separate access barring mechanisms into a unified control framework that provides comprehensive congestion control coverage. By combining these mechanisms rather than maintaining them separately, the invention reduces redundant signaling and radio resource usage while preserving the comprehensive coverage needed for effective congestion control across all protocol layers

AI summary
An access control technology in a next generation mobile communication network is disclosed. More specifically, disclosed is a technology for controlling an access control operation of a terminal through an integrated category by various methods and layers. One embodiment provides a method by which a terminal performs integrated access control, comprising the steps of: receiving, from a base station, system information including information for access control; indicating access category information from an NAS layer to an AS layer of the terminal when an access attempt is triggered; confirming whether access barring parameter information is included in the system information; and controlling an access barring check operation in the AS layer by using at least one of the access category information and the access barring parameter information.
