ACDC Barring Check Skips ACB for Prioritized Apps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems lack a method to differentiate and manage network access for specific applications during congestion, leading to unnecessary service delays and resource wastage in overloaded networks.
Innovation Solution
Implementing a method for user equipment (UE) to perform application-specific congestion control (ACDC) barring checks, which determine the category of the application and skip or perform access class barring (ACB) checks based on received information, thereby optimizing network access and resource allocation.

Engineering Contradiction Analysis
1Productivity
If application-specific congestion control (ACDC) barring checks are implemented to differentiate network access for specific applications, then network resource allocation efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the network access control mechanism by introducing application-specific congestion control (ACDC) barring checks that operate independently from traditional access class barring (ACB). The ACDC mechanism divides network access management into application-level categories, allowing different applications to be treated differently during congestion conditions. This segmentation enables differentiated resource allocation without requiring complete redesign of the existing ACB system.
Solution Approach 2:
The patent implements preliminary action by performing ACDC barring checks before allowing network access during congestion conditions. The user equipment (UE) is pre-configured with ACDC barring information received from the network, and when congestion is detected, the ACDC check is performed first to determine whether the specific application should be allowed to access the network. This preliminary filtering prevents unnecessary access attempts and reduces network load before traditional ACB checks are applied.
2Reliability
If ACDC barring checks are performed to prevent service delays in congested networks, then service quality is improved, but processing time increases
Solution Approach 1:
The patent applies partial action by selectively performing ACDC barring checks only for specific applications that require differentiated treatment during congestion conditions. Not all applications undergo the same level of checking - the system identifies and applies ACDC checks only where necessary based on application category and network conditions. This selective approach reduces overall processing time while maintaining service quality for critical applications.
Solution Approach 2:
The patent uses copying by reusing the existing ACB check infrastructure and logic for applications that do not require ACDC treatment. Instead of creating entirely new check mechanisms, the system copies and adapts the proven ACB framework, applying ACDC checks only where differentiation is needed. This approach minimizes processing overhead by leveraging existing validated code paths.
3Speed
If ACDC barring information is used to skip ACB checks for prioritized applications, then network access speed is improved, but loss of information increases
Solution Approach 1:
The patent introduces an intermediary mechanism where the ACDC barring check acts as a mediator between the application layer and the ACB check. The ACDC check evaluates application-specific congestion control parameters and determines whether ACB checks should be skipped or applied. This intermediary layer ensures that skipping ACB checks is done safely based on predefined ACDC barring information, preventing loss of access control information while enabling faster access for prioritized applications.
Solution Approach 2:
The patent applies local quality by allowing different levels of ACB check application based on application category. Some applications receive expedited treatment with ACB checks skipped entirely, while others undergo full ACB verification. The ACDC barring information is applied locally to specific application types rather than uniformly across all applications, enabling speed improvements for critical services without compromising the integrity of access control for other applications.
Data Source
AI summary
A disclosure of the present specification provides a network access blocking method performed by a user equipment. The method may comprise the steps of: receiving application specific congestion control for data communication (ACDC) blocking information and access class barring (ACB) blocking information; determining the category of an application being executed according to a network access attempt by the application; performing an ACDC blocking check on the basis of the determined category and the received ACDC blocking information. Here, when the network access attempt by the application is not blocked as a result of the ACDC blocking check, an ACB blocking check on the basis of the ACB blocking information may be skipped.
