Terminal Access Control Using Capability-Based Network Barring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge in 3GPP mobile communication networks is to effectively implement access control for terminal devices with varying capabilities, such as different radio frequency bandwidths and peak data transmission rates, to ensure efficient network management.
Innovation Solution
An access method and apparatus that utilize first and second information to determine whether a terminal device can access the network based on its peak data rate, baseband processing bandwidth, and other capabilities, using higher layer parameters like layer number, modulation order, and scaling factor to bar or allow access.

Engineering Contradiction Analysis
1Productivity
If access control is implemented for terminal devices with different capabilities, then network management efficiency is improved, but device complexity increases
Solution Approach 1:
The patent applies parameter changes by introducing specific capability parameters (baseband processing bandwidth, peak data transmission rate) to differentiate terminal devices. The network device uses these parameters to determine access control policies, transforming the access control mechanism from a generic approach to a parameter-driven approach that adapts to different terminal capabilities.
Solution Approach 2:
The patent segments terminal devices into different types (first-type and second-type) based on their capability parameters. This segmentation allows the network to apply different access control rules to different device groups, improving management efficiency while maintaining clear distinction between device categories through specific threshold comparisons.
2Measurement precision
If detailed capability information is collected for access control, then access determination accuracy is improved, but information overhead increases
Solution Approach 1:
The patent extracts only the essential capability parameters (baseband processing bandwidth and peak data transmission rate) needed for access control decisions, rather than collecting comprehensive terminal capability information. This extraction approach maintains access determination accuracy by focusing on the most relevant parameters while reducing information overhead by excluding unnecessary details.
Solution Approach 2:
The patent applies local quality by collecting different amounts of capability information for different terminal types. First-type terminals provide detailed capability parameters for precise access control, while second-type terminals use simplified parameters. This localized information collection strategy optimizes the balance between accuracy and overhead for each terminal category.

AI summary
This application provides an access method and an apparatus. The method includes: A terminal device receives first information. The first information indicates that access of a first-type terminal device is barred or allowed, and the first-type terminal device meets a first condition. The terminal device accesses or is barred from accessing the network device based on the first information. By implementing the foregoing method, access control can be performed on the terminal device.
