Border Control Aggregator for PSTN Connectivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Maintaining an IP Multimedia Subsystem (IMS) network in-house is cumbersome for organizations due to the need for costly hardware management and integration with the public switched telephone network (PSTN), requiring manual reconfiguration and maintenance of circuit-switched connections.
Innovation Solution
Providing remotely hosted and scalable telecommunications services that eliminate the need for in-house infrastructure and network connection management, using a computing environment with network management services, media controls, load balancers, IVR services, border controls, and a border control aggregator to manage and scale IMS services and connect to PSTN through peering providers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If organizations maintain an IMS network in-house, then they have full control over telephony services, but they incur costly hardware management and manual reconfiguration expenses
Solution Approach 1:
The patent extracts the complex IMS network infrastructure and PSTN integration requirements from the organization's internal operations and relocates them to a remote service provider's data center. The border control aggregator and border control elements are deployed at the service provider's facility, removing the burden of hardware management, scaling, and PSTN connection maintenance from the organization while preserving full control over telephony services through virtualized network functions.
2Adaptability or versatility
If organizations maintain in-house IMS network infrastructure, then they can customize services, but hardware must be manually added, reallocated, or reconfigured in response to demand
Solution Approach 1:
The patent implements self-service capabilities through virtualized network functions and automated provisioning systems. The border control aggregator and other IMS elements are deployed as virtual machines that can be automatically instantiated, scaled, and reconfigured through software without manual hardware intervention. This allows the system to adapt to changing service demands automatically while maintaining customization capabilities through software configuration.
3Ease of operation
If organizations integrate IMS network with PSTN in-house, then they provide connectivity to circuit-switched connections, but they must establish and maintain T1 or legacy circuits with providers
Solution Approach 1:
The patent introduces a border control aggregator as an intermediary component that handles all PSTN connectivity requirements. This aggregator consolidates multiple T1 and legacy circuit connections from different PSTN providers into a single centralized interface. Organizations connect to the service provider's border control aggregator, which then manages all circuit-switched connections to external PSTN networks, eliminating the need for organizations to directly establish and maintain complex circuit connections.
4Reliability
If organizations host IMS services locally, then they ensure data security, but they bear the cost of hardware and service instance scaling
Solution Approach 1:
The patent implements a universal hosted service platform that combines multiple functions: secure data hosting, automated scaling, PSTN integration, and IMS service delivery. The service provider's infrastructure provides a multi-functional solution where virtualized network functions can be dynamically allocated and scaled while maintaining security through centralized control and isolation mechanisms. Organizations gain access to this universal platform without bearing the costs and complexities of building and maintaining their own scaling infrastructure.
