Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The growing number of applications on user equipment (UEs) causes network inefficiencies and congestion in Radio Access Networks (RAN) and Core Networks (CN), necessitating a solution to prioritize and restrict certain applications during emergency situations or when network capacity thresholds are exceeded, while ensuring compliance with regional/national regulations.
Innovation Solution
Implementing Application Specific Congestion Control for Data Communications (ACDC)/Application and Service Access Control (ASAC) by using a preconfigured 'white list' of allowed applications, prioritizing emergency services, and dynamically managing application categories to alleviate network congestion through prioritization and restriction based on network conditions and geographical regions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all applications are allowed to access the network simultaneously, then application diversity and user service quality are improved, but network congestion and resource exhaustion occur
Solution Approach 1:
The patent segments applications into different categories (emergency services, critical communications, non-essential applications) and assigns different access priorities to each category. This segmentation allows the network to manage diverse applications while controlling overall network load by restricting access for lower-priority categories during congestion conditions.
Solution Approach 2:
The patent changes the access parameter (permission to access network) based on network conditions and application category. When network capacity is exceeded, the system dynamically adjusts access parameters by blocking non-essential applications while maintaining access for essential services, thus resolving the contradiction between application diversity and network capacity.
2Quantity of substance
If network congestion control is implemented by blocking applications, then network capacity is preserved, but application accessibility and user service quality deteriorate
Solution Approach 1:
The patent applies different access control policies to different application categories based on their specific needs. Emergency services and critical communications receive preferential treatment with higher accessibility, while non-essential applications are restricted. This local quality approach ensures network capacity is preserved overall while maintaining ease of operation for critical applications.
3Reliability
If emergency services are prioritized during congestion, then critical communication reliability is improved, but non-essential application access is restricted
Solution Approach 1:
The patent performs preliminary classification of applications into categories before congestion occurs. Emergency services and critical communications are pre-identified and assigned high-priority status. When congestion occurs, this preliminary classification enables immediate enforcement of access control without compromising critical communications, while non-essential applications are automatically restricted.
Data Source
AI summary
Technology for a network element configured to apply Application Specific Congestion Control for Data Communication (ACDC) in a wireless network is disclosed. The network element can determine to apply ACDC in the wireless network to mitigate overload of the wireless network. The network element can process barring information for one or more ACDC categories for transmission to a user equipment (UE) when ACDC is applied in the wireless network. The barring information can indicate that the UE is prevented from accessing the network for applications associated with the one or more ACDC categories when ACDC is applied in the wireless network.
