Virtual Media Gateways for Distributed Telecommunication Resource Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telecommunication systems face inefficiencies in managing resources, particularly in scaling signaling and media functions independently, leading to unnecessary resource utilization and increased costs due to the centralized nature of bearer plane backhaul.
Innovation Solution
A distributed telecommunication system is implemented, separating components into control nodes and bearer nodes, with virtual media gateways providing access to media resources, allowing for independent scaling of signaling and media functions based on demand, reducing the need for additional resources and optimizing network operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional centralized telecommunication systems are used, then resource management is simplified, but resource utilization efficiency deteriorates and costs increase
Solution Approach 1:
The patent segments the telecommunication system into control nodes and bearer nodes, separating signaling functions from media transfer functions. This allows independent scaling and optimization of each component, improving resource utilization efficiency while maintaining manageable complexity through modular architecture.
Solution Approach 2:
The patent implements virtual media gateways that can serve multiple control nodes simultaneously, allowing a single bearer node to provide services to multiple control nodes. This multi-functionality improves resource utilization by sharing infrastructure across multiple functions while maintaining the ability to scale independently.
2Productivity
If additional components are added to meet increasing demand, then service capacity increases, but resource management complexity and costs increase
Solution Approach 1:
The patent enables dynamic scaling where control nodes and bearer nodes can be added or removed independently based on demand. Virtual media gateways can be dynamically allocated to serve different control nodes, allowing the system to adapt to changing service capacity requirements without proportionally increasing overall complexity.
Solution Approach 2:
The patent uses virtualization to create virtual copies of media gateways that can be instantiated as needed. These virtual media gateways share the underlying physical infrastructure, allowing service capacity to scale without proportionally increasing physical hardware complexity or management overhead.
3Device complexity
If centralized bearer plane backhaul is used, then system architecture is simplified, but network flexibility and scaling capability deteriorate
Solution Approach 1:
The patent separates control plane and bearer plane functions into different nodes, allowing the bearer plane to be distributed across multiple bearer nodes while the control plane remains centralized or distributed across control nodes. This segmentation enables network flexibility and independent scaling while maintaining manageable architectural complexity.
Solution Approach 2:
The patent introduces virtual media gateways as intermediaries between control nodes and bearer nodes. These virtual gateways enable flexible routing and allocation of media resources across multiple bearer nodes, providing network flexibility without requiring complex direct connections between all control nodes and all bearer nodes.
