Multi-Protocol Session Controller for VoIP Network Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VoIP network infrastructure lacks a comprehensive solution for enabling seamless service delivery across different networks, including carrier-carrier, carrier-enterprise, and carrier-residential peering, due to limitations in existing multi-protocol signaling and session control mechanisms.
Innovation Solution
A system comprising multi-protocol session controllers and a comprehensive management system that processes calls, generates call detailed records, and provides analytics, routing rules, and quality monitoring, enabling interoperability between SIP and H.323 networks, and supporting features like transcoding, media routing, and quality of service management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If multiple infrastructure components are integrated and collocated on one physical component, then network resource optimization is achieved, but device complexity increases
Solution Approach 1:
The patent combines multiple VoIP infrastructure components (gateway, gatekeeper, proxy server, softswitch, session border controller) into a single collocated system. This integration allows these components to share physical resources and coordinate efficiently, optimizing network resource utilization while maintaining distinct functional responsibilities for each component type within the unified infrastructure.
Solution Approach 2:
The integrated infrastructure component is designed to perform multiple functions simultaneously - handling call routing, protocol conversion, authentication, and session management. This multi-functional approach allows a single physical system to serve as gateway, gatekeeper, and border controller, reducing the need for separate dedicated hardware for each function.
2Adaptability or versatility
If comprehensive service delivery across different networks is enabled, then adaptability improves, but device complexity increases
Solution Approach 1:
The session border controller is designed with multi-protocol support (SIP, H.323, MGCP) and the ability to interwork between different network types (PSTN, VoIP, mobile networks). This universal design enables comprehensive service delivery across carrier-carrier, carrier-enterprise, and carrier-residential networks while consolidating multiple protocol handling capabilities into a single controller.
Solution Approach 2:
The session border controller acts as an intermediary element between different networks and protocol domains. It mediates call setup, authentication, and media routing between heterogeneous networks, providing a standardized interface that simplifies the complexity of direct multi-network integration while maintaining high adaptability.
3Reliability
If real-time call processing and quality monitoring are implemented, then service quality improves, but use of energy increases
Solution Approach 1:
The system implements automated call admission control, quality monitoring, and resource management functions that operate autonomously without requiring manual intervention. The session border controller automatically monitors call quality metrics, manages bandwidth allocation, and makes real-time decisions about call admission and routing, reducing the need for energy-intensive manual operations while maintaining high service quality.

AI summary
A session controller coupled to a database and configured to receive an indication associated with an ingress call is disclosed. The disclosed session controller is further configured to compare at least one of a network capacity, a call-peer bandwidth, or a number of active call-legs associated with the ingress call session against a respective threshold, and to reject the ingress call when a respective threshold is exceeded.
