Wireless Traffic Control via Application-Based Barring Parameters
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in effectively controlling network traffic in mobile communication systems, particularly in managing data transmission in RRC connected mode, which can lead to inefficient use of network resources.
Innovation Solution
A method is introduced that involves transmitting information about installed applications to a base station, receiving barring parameters, and determining whether to bar data transmission based on these parameters at various levels (application, ACDC category, PDCP entity, or RLC level), with the option to exclude barred data from buffer status reports, ensuring efficient traffic control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data transmission is allowed in RRC connected mode, then network resource utilization is improved, but network traffic congestion increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the barring factor parameter to control data transmission. The base station receives information about installed applications and their data transmission characteristics, then determines appropriate barring parameters to regulate traffic volume while maintaining necessary network resource utilization for connected mode UEs.
Solution Approach 2:
The patent implements dynamic traffic control by continuously monitoring application information and adjusting barring parameters in real-time. The system dynamically determines whether to bar data transmission based on current network conditions and application requirements, allowing flexible adaptation between allowing transmission for resource utilization and blocking for traffic control.
2Measurement precision
If traffic control is implemented at multiple levels (application, ACDC category, PDCP, RLC), then traffic control precision is improved, but system complexity increases
Solution Approach 1:
The patent segments traffic control into multiple hierarchical levels: application level, ACDC category level, PDCP entity level, and RLC level. Each level provides progressively finer control granularity, allowing precise traffic management by selecting the appropriate segmentation level based on control requirements without unnecessarily increasing overall system complexity.
Solution Approach 2:
The patent adds a new dimension to traffic control by introducing ACDC category classification alongside traditional protocol layer control. This multi-dimensional approach enables precise traffic control by combining category-based filtering with layer-based regulation, achieving fine-grained control while managing complexity through structured organization.

AI summary
Disclosed are a traffic control method and terminal, the traffic control method comprising the steps of; transmitting, to a base station, a first message including information of an installed application; receiving a second message including information of a barring parameter for the application; determining whether to bar a data transmission on the basis of the barring parameter according to the generation of data from the application, during an operation in a radio resource control (RRC) connection mode; and selectively transmitting the data to the base station according to a determination result.
