Application-Aware Access Control for Mobile Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current access control methods in 3GPP mobile networks are not application-aware, unable to differentiate between specific applications, and lack coordination in controlling network access, especially during congestion, leading to inefficient traffic management.
Innovation Solution
Implementing an application-aware congestion control model in user equipment (UE) that receives and combines access control messages from the network to determine a combined access level for applications, limiting network access based on priority, probability, or time barriers, thereby optimizing network resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current access control methods are used, then network access is controlled, but applications cannot be differentiated and traffic management is inefficient
Solution Approach 1:
The patent segments access control into multiple independent services (first access control service and second access control service), each providing different access control information. This allows the system to differentiate between various applications and traffic types while maintaining manageable complexity through modular service architecture.
Solution Approach 2:
The patent introduces a new dimension of application awareness by combining access control information from multiple services to determine application-specific access levels. This multi-dimensional approach enables differentiation between applications without proportionally increasing overall system complexity.
2Reliability
If multiple access control services are implemented, then more comprehensive control is achieved, but coordination between services becomes cumbersome
Solution Approach 1:
The patent merges access control information from multiple independent access control services into a unified application access level. The UE combines the first access control information and second access control information to determine a single application access level, achieving comprehensive control while simplifying coordination through centralized combination logic.
Solution Approach 2:
The system implements feedback mechanisms where the UE monitors access control information from multiple services and dynamically adjusts application access levels based on the combined information. This feedback loop ensures reliable access control while automatically managing the coordination complexity between services.
3Productivity
If network access is limited during congestion, then network resources are optimized, but critical applications may be affected
Solution Approach 1:
The patent applies local quality by determining different access levels for different applications based on their specific characteristics and requirements. Critical applications receive higher access levels while non-essential applications receive lower access levels, allowing network resource optimization without affecting critical services.
Solution Approach 2:
The system dynamically changes access level parameters for different applications based on network conditions and application priorities. By adjusting the application access level parameter, the system can optimize network resource efficiency during congestion while ensuring critical applications maintain sufficient access rights.

AI summary
A user equipment (UE) is configured to receive, from a network, a first access control message and a second access control message. The first access control message corresponds to a first access control service, and the second access control message corresponds to a second access control service. The first and second access control messages include access control information for controlling access to the network for at least one application on the UE. The UE is also configured to determine a combined access level for the at least one application based on the first and second access control messages and to limit access to wireless communications for the at least one application based on the combined access level.
