Dynamic Bandwidth Allocation for VoIP Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Subscribers of broadband access services require dynamic adjustment of bandwidth to accommodate higher bandwidth needs for voice and video applications in VoIP networks, as existing methods do not efficiently manage bandwidth allocation based on application requirements.
Innovation Solution
A method that dynamically reconfigures broadband access bandwidth by detecting signaling messages, such as application request and disconnect messages, to increase or decrease bandwidth allocation as needed for VoIP and video services, allowing subscribers to invoke higher bandwidth when required and return to baseline levels when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If basic bandwidth allocation is maintained for all subscribers, then network resource utilization is optimized, but voice and video application quality deteriorates due to insufficient bandwidth
Solution Approach 1:
The patent implements dynamic bandwidth allocation that adjusts bandwidth assignment in real-time based on application requirements. The system transitions from static basic bandwidth allocation to dynamic adjustment, where bandwidth is increased for voice/video applications and reduced for basic data transmissions, resolving the contradiction between maintaining basic utilization and providing quality for specific applications
Solution Approach 2:
The system changes the bandwidth parameter dynamically based on application type detection. When voice or video applications are detected through signaling messages, the bandwidth parameter is increased; when basic data transmissions are detected, the parameter remains at basic levels. This parameter change approach allows the system to provide high quality for specific applications while maintaining overall resource efficiency
2Reliability
If bandwidth is increased for voice and video applications, then application quality improves, but network resource utilization deteriorates due to excessive bandwidth allocation during non-use periods
Solution Approach 1:
The system employs periodic monitoring of signaling messages to detect application start and stop conditions. Bandwidth is allocated in periodic cycles - increased when applications are detected and reduced when they terminate. This periodic adjustment ensures quality during use while recovering resources during non-use periods, resolving the contradiction between application quality and resource utilization
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors signaling messages for application status changes. When disconnect messages are received, the system feedbacks by reducing bandwidth allocation back to basic levels. This feedback loop ensures that bandwidth is not excessively allocated during non-use periods while maintaining quality during active applications
3Measurement precision
If manual bandwidth reconfiguration is required for each application, then bandwidth allocation precision improves, but system complexity increases due to manual intervention requirements
Solution Approach 1:
The system performs automatic bandwidth reconfiguration by detecting signaling messages without requiring manual intervention. The network infrastructure itself monitors application requests and autonomously adjusts bandwidth allocation based on detected application types. This self-service approach maintains precise bandwidth allocation while eliminating the complexity of manual configuration
Solution Approach 2:
The patent uses signaling messages as intermediaries to convey application information from subscribers to the network system. These messages serve as mediators that enable the system to detect application requirements and trigger appropriate bandwidth adjustments automatically. The intermediary mechanism preserves allocation precision while reducing system complexity by automating the detection and response process

AI summary
A method and apparatus for providing a method to enable subscribers of broadband access services, such as Digital Subscriber Loop based or Cable based broadband access services, to dynamically reconfigure their access arrangements as a function of the application they invoke are disclosed. Subscribers that subscribe to a basic amount of bandwidth can dynamically increase their bandwidth allocation when they invoke a voice or video application by simply requesting the application. The present invention provides a method for broadband service providers to dynamically adjust access bandwidth allocation for subscribers by detecting signaling messages, such as application request setup messages and disconnect messages.
