Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems lack a method to differentiate and manage network access for specific applications during network congestion, leading to inefficient resource allocation and poor user experience.
Innovation Solution
Implementing Application-Specific Congestion Control (ACDC) that provides application-related information and configuration settings to User Equipment (UE), allowing for differentiated access barring and priority management based on application categories and priorities, thereby optimizing network resource allocation.

Engineering Contradiction Analysis
1Productivity
If application-specific congestion control is implemented, then network resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the congestion control mechanism by introducing application-specific parameters (ACDC parameters) that operate alongside existing access control parameters. The network divides congestion control into multiple independent parameter sets, each associated with specific applications, allowing granular control without requiring complete redesign of the congestion control system. This segmentation enables efficient resource allocation while maintaining manageable system complexity.
Solution Approach 2:
The patent adds a new dimension to congestion control by introducing application-layer parameters (ACDC parameters) that work in conjunction with existing radio access network parameters. This creates a multi-dimensional control framework where congestion management occurs at both the radio access level and the application-specific level, enabling more nuanced resource allocation without fundamentally altering the existing control architecture.
2Reliability
If differentiated access barring is implemented, then service reliability is improved, but system complexity increases
Solution Approach 1:
The patent applies local quality by providing different congestion control parameters to different applications based on their specific requirements. Critical applications receive parameters that ensure high reliability during congestion, while non-critical applications receive parameters that allow more aggressive congestion control. This localized differentiation improves service reliability for essential applications without requiring uniform complexity across all system components.
Solution Approach 2:
The patent introduces dynamic congestion control where parameters can be adjusted based on network conditions and application priorities. The system can dynamically allocate resources by modifying ACDC parameters for specific applications during congestion events, allowing the system to adapt to changing conditions while maintaining manageable complexity through parameter-based control rather than structural changes.

AI summary
One embodiment of the present specification provides a method of attempting network access by user equipment (UE). The method comprises the steps of: acquiring, from an upper layer, information related to an application attempting network access when an application specific congestion control for data communication (ACDC) is configured; determining an ACDC category on the basis of the acquired information related to an application; and performing an ACDC test on the basis of the determined ACDC category, wherein a network access trial can be barred or allowed for each application according to the ACDC test.
