ACDC Access Control for Application Prioritization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing ACDC access control mechanism only makes admission judgments when a terminal is in an idle state, leading to unfair prioritization and management of applications, as a low-priority application can access the network without further ACDC judgments after a connection is established, resulting in free-riding and lack of control over different applications.
Innovation Solution
An access control method that acquires identification information of a second application after a first connection is established, makes an ACDC judgment based on blocking parameters, and establishes a connection or blocks communication accordingly, ensuring that each application undergoes an ACDC judgment upon initial access, regardless of network state, to maintain fairness and control.

Engineering Contradiction Analysis
1Device complexity
If ACDC only makes admission judgments when terminal is in idle state, then the access control mechanism is simple, but low-priority applications can free-ride on established connections without proper control
Solution Approach 1:
The patent applies preliminary action by performing ACDC admission judgment for each application before allowing network access, even when the terminal is in connected state. This ensures that priority control is established in advance for each application before it can utilize network resources, preventing low-priority applications from free-riding on connections established by high-priority applications.
2Reliability
If ACDC judgment is made for every application access, then application prioritization control is improved, but the access control process becomes more complex
Solution Approach 1:
The patent applies dynamics by making the ACDC judgment process adaptive to the terminal's state. When the terminal is in idle state, ACDC judgment is performed for each application access. When the terminal is in connected state, ACDC judgment is performed only when necessary (e.g., when resource allocation changes or specific triggers occur), rather than for every single access attempt. This dynamic approach maintains prioritization control while reducing unnecessary complexity.

AI summary
Provided are an access control method and device. The access control method includes: after a first connection of a first application has been established between a terminal and a network, obtaining identification information of a second application before performing ACDC determination for the second application; according to the identification information, obtaining a blocking parameter of the second application; according to the blocking parameter, performing ACDC determination for the second application, and obtaining a determination result for whether the second application is allowed to perform network communication or not; when the determination result indicates that the second application is allowed to perform network communication, establishing a second connection between the terminal and the network for the second application, or allowing the second application to transmit information on the first connection.
