Application Status Change Notification for Bandwidth Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional network connection systems in mobile networks cannot effectively prioritize and control bandwidth for specific applications, such as IP phones, leading to dissatisfaction among users due to the inability to differentiate and manage communication bandwidths for various applications.
Innovation Solution
An application status change notification program that dynamically adjusts communication bandwidth for each type of application on a mobile information communication terminal by detecting application types, obtaining terminal identification information, and sending this information to a bandwidth control system, which then applies preferential control or bandwidth settings based on predefined policies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IP packets are transferred on a best-effort basis in a typical network connection configuration, then the network system is simple to operate, but it is impossible to preferentially control communication bandwidth for specific applications
Solution Approach 1:
The patent introduces an application status change notification program as an intermediary component that bridges the gap between simple best-effort network configuration and application-specific bandwidth control. This program monitors application status changes and sends notifications to the bandwidth control system, enabling preferential control without complex router presetting. The intermediary handles the complexity of application identification and bandwidth management, keeping the network configuration simple while achieving versatile application-specific control.
2Adaptability or versatility
If the IP address of a specific smartphone is preset at the router to preferentially control connections, then bandwidth control is achieved, but all applications of that smartphone are preferentially controlled including non-critical applications
Solution Approach 1:
The patent segments the bandwidth control at the application level rather than the device level. Instead of controlling all traffic from a smartphone, the application status change notification program identifies specific applications and sends notifications only for those applications to the bandwidth control system. This segmentation enables fine-grained control where only critical applications receive preferential treatment while non-critical applications use standard bandwidth, resolving the issue of overly broad control.
3Adaptability or versatility
If connections are preferentially controlled only to a specific service server, then some application control is achieved, but it is difficult to identify all IP addresses of collaborating servers for services like IP phones
Solution Approach 1:
The patent implements self-service by having the terminal device itself perform the identification and notification function. Instead of requiring the network system to identify and track multiple collaborating server IP addresses, the application status change notification program on the terminal automatically detects when critical applications are running and sends notifications directly. This shifts the identification burden from the network side to the terminal side, simplifying server detection while maintaining application-specific control.
