Network Access Control via Dynamic UE Category Mapping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of user equipment (UEs) in wireless communication systems necessitates efficient methods for transmitting and receiving data and control information using limited radio resources, while also requiring improved network access control and fair access opportunities for different types of UEs to ensure minimum system load and enhanced throughput.
Innovation Solution
The solution involves mapping information that indicates network slices, IP addresses, or access causes for each access category, allowing or denying access attempts based on these criteria, and dynamically allocating access classes to UEs based on subscription information, service types, and network slices to manage resource allocation and access opportunities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the number of user equipment (UEs) increases to provide more communication services, then the communication service coverage and user capacity improve, but the available radio resources per UE decrease and system congestion increases
Solution Approach 1:
The patent segments the network access process into multiple access categories (0-9) based on service types and UE characteristics. Each category has dedicated access opportunities and resource allocations, allowing simultaneous service of multiple UEs with different requirements without mutual interference, thus increasing overall system capacity while maintaining resource efficiency
Solution Approach 2:
The patent dynamically allocates access categories and opportunities based on real-time network conditions, service types, and UE characteristics. The base station can adjust which access categories are permitted at different times and under different conditions, enabling flexible resource management that adapts to changing system load and service demands
2Reliability
If network access control is implemented to manage system load, then system stability and resource allocation improve, but access delay and complexity increase
Solution Approach 1:
The patent uses access category parameters (0-9) as controllable variables to manage network access. By changing which parameters are permitted based on system conditions, the network can control access without complex decision-making processes. The simplicity of parameter-based control reduces implementation complexity while maintaining effective load management
Solution Approach 2:
The patent pre-defines multiple access categories with different characteristics and requirements before network operation begins. This preliminary classification allows the system to quickly determine appropriate access control actions without real-time complex analysis, reducing both access delay and control complexity while maintaining system stability
3Adaptability or versatility
If differentiated access opportunities are provided for different UE types and services, then service quality and fairness improve, but system overhead and complexity increase
Solution Approach 1:
The patent applies different access category configurations to different UEs and services based on their specific requirements. Each UE type or service can be assigned to appropriate access categories with tailored parameters, providing localized optimization without requiring complete system redesign. This selective differentiation reduces overall complexity compared to universal complex management
4Productivity
If more radio resources are allocated to transmit data and control information, then data throughput and service capacity increase, but resource availability for other UEs decreases
Solution Approach 1:
The patent segments radio resources into category-specific allocations corresponding to different access categories. Each category receives resources optimized for its specific service requirements, eliminating waste from one-size-fits-all allocation. This segmented resource distribution increases total system throughput by ensuring each resource unit serves its most appropriate function
Solution Approach 2:
The access category framework provides a universal mechanism that can accommodate multiple service types and UE configurations through a single structured approach. This multi-functional system handles diverse traffic types (voice, data, signaling, emergency services) using the same category-based resource allocation principle, improving overall resource utilization efficiency

AI summary
In a wireless communication system of the present invention, a user equipment (UE) can receive mapping information for each of a plurality of connection categories. The UE can receive barring information for the plurality of connection categories. The UE can determine whether to perform a connection attempt to a network on the basis of the barring information and a connection category to which UE data belongs according to the mapping information.
