Dynamic VoIP Transmission Mode Switching for Network Congestion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VoIP and VoLTE networks face capacity issues due to congestion, leading to call blockages and revenue loss for network operators, primarily because of insufficient network resources along the transmission path.
Innovation Solution
Implement a system where wireless devices and access nodes dynamically switch between two data transmission modes based on available network resources, with the second mode requiring fewer resources, allowing for continued communication even during congestion, and reverting back when resources become available.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network transmits data packets using the first mode of data transmission, then the quality of service is maintained, but the network resources are insufficient during congestion leading to call blockages
Solution Approach 1:
The system dynamically switches between first and second modes of data transmission based on real-time network resource availability. The access node monitors network conditions and transitions the transmission mode accordingly, allowing the system to adapt to changing resource conditions and maintain call continuity during congestion while using optimal resources
Solution Approach 2:
The system changes the transmission parameters by switching between different modes of data transmission. The first mode uses higher resource consumption parameters for normal conditions, while the second mode uses reduced resource parameters during congestion, allowing the system to maintain functionality under varying resource constraints
2Reliability
If the network switches to the second mode of data transmission during congestion, then the call continuity is maintained, but the service quality may be reduced
Solution Approach 1:
The system dynamically adjusts the transmission mode based on network conditions, switching to the second mode only when necessary during congestion and reverting to the first mode when resources are sufficient, thereby maintaining service quality when possible while ensuring call continuity when needed
Solution Approach 2:
The system applies the second mode of transmission partially, only during periods of network congestion, rather than continuously. This allows the system to maintain high service quality during normal operation while providing a fallback mechanism during adverse conditions
3Productivity
If the network monitors and switches transmission modes continuously, then the capacity is improved, but the system complexity increases
Solution Approach 1:
The access node continuously monitors network resource availability and provides feedback to determine when to switch between transmission modes. This feedback mechanism enables automatic adaptation to changing conditions, improving VoIP capacity through dynamic resource management without requiring complex manual intervention

AI summary
Systems and methods are described for improving capacity of voice services for data packet transmission through a wireless network. Application requirements including a data rate for a wireless device may be determined. An access node may determine available resources to transmit data as indicated by the application requirements. The wireless device and the access node may communicate data transmissions wirelessly for use by the wireless device application. Data transmission may be in a first mode or in a second mode depending whether there are sufficient available network resources for the determined data rate. The first and second transmission modes may be generated from a common input such as a wireless device user's voice; however, the second mode of data transmission may be converted in order to consume less network resources.
