Solution Overview

Problem

The challenge is to effectively control network access for applications on mobile devices during network congestion, ensuring that critical services like disaster bulletin boards and voice services function while reducing the network burden, and managing resource usage efficiently.

Innovation Solution

A method and device for controlling network access by acquiring application configuration information and receiving access control information, determining whether to allow applications to access the network based on user equipment class and application classification, using protocol stack upper layers or access layers to manage access permissions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If applications are allowed to access the network freely, then application functionality is maintained, but network congestion increases and resources are overwhelmed

Engineering Contradiction:

Improveapplication functionalityVSAvoidnetwork congestion

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments applications into different priority levels (first priority, second priority, third priority) based on their importance and resource requirements. This segmentation allows the network to differentiate between critical applications (like voice services and disaster bulletin boards) and non-critical applications, applying different access control policies to each segment to manage congestion while ensuring critical services maintain functionality

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent implements local quality control by applying different access control strategies to different application types. Critical applications receive guaranteed access permissions while non-critical applications are subject to restrictions during congestion. This localized differentiation ensures that network resources are allocated according to specific application needs rather than applying a uniform policy

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If access control is implemented to reduce network burden, then network congestion is reduced, but application access flexibility is limited

Engineering Contradiction:

Improvenetwork burdenVSAvoidapplication access flexibility

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic access control where the network device monitors network status in real-time and adjusts access permissions accordingly. When network congestion is detected, the device dynamically modifies which applications are allowed to access the network, prioritizing critical services while restricting non-critical ones. This dynamic adjustment maintains access flexibility for essential applications while reducing overall network burden

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of access permission based on network conditions and application priority. By modifying access permissions dynamically (granting or restricting access) according to network status and application classification, the system reduces network burden while preserving necessary access flexibility for high-priority applications

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If all applications are allowed to access during congestion, then application diversity is maintained, but critical services may be affected

Engineering Contradiction:

Improveapplication diversityVSAvoidcritical service availability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments applications into priority groups, with critical services (voice services, disaster bulletin boards) placed in the first priority group with guaranteed access permissions. This segmentation ensures that even when network congestion occurs and application diversity is restricted, critical services maintain their access rights and reliability is preserved

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent applies local quality control by giving special access permissions specifically to critical services while restricting access for non-critical applications during congestion. This localized differentiation ensures that critical services receive the quality of service they need to maintain reliability, while other applications are managed to preserve overall application diversity where possible

Inventive Principle:

Principle #3Local quality

AI summary

Embodiments of the present application provide a method for controlling access of an application to a network, and a device. The method includes: acquiring application configuration information, where the application configuration information includes identification information of an application that is allowed to access a network or identification information of an application that is prohibited from accessing a network. The method also includes receiving access control information that is sent by an access network device, and determining, according to the application configuration information and the access control information, whether to allow an application of user equipment to access the network.
