UCCI Cloud Interconnection Bypassing PSTN for Voice and Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in establishing cloud-based voice and video calling services across different administrative domains of communication service providers without traversing the public switched telephone network (PSTN).
Innovation Solution
The implementation of a unified communications and collaboration interconnection (UCCI) system, which is a cloud-based interconnection that connects separate administrative domains of communication service providers, allowing for the establishment of cloud-based call connections without using the PSTN.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If cloud-based calling services traverse the PSTN to connect different administrative domains, then call connectivity is achieved, but call termination costs increase and service versatility is limited
Solution Approach 1:
The system segments the calling service into two distinct pathways: PSTN traversal for legacy compatibility and direct IP-based routing for cost-effective cloud-to-cloud connections. This segmentation allows selective routing based on service type and destination, reducing unnecessary PSTN usage and associated costs while maintaining support for both traditional and modern services
Solution Approach 2:
A cloud-based session border controller (SBC) acts as an intermediary between different administrative domains, enabling direct IP-based call routing without PSTN traversal. The SBC mediates authentication, authorization, and call setup between cloud providers, allowing cost-effective direct routing while maintaining compatibility with existing protocols and services
2Loss of energy
If direct IP-based routing is implemented between administrative domains, then call termination costs are reduced, but interconnection complexity increases
Solution Approach 1:
The cloud-based session border controller serves as a standardized intermediary that simplifies direct IP-based routing by handling protocol translation, authentication, and call management. This intermediary abstracts the complexity of direct interconnection, providing a uniform interface between different administrative domains while enabling cost-effective routing
Solution Approach 2:
The session border controller is designed as a universal component that performs multiple functions including authentication, authorization, protocol translation, and call routing. This multi-functionality consolidates various interconnection requirements into a single standardized platform, reducing overall system complexity while enabling direct IP-based routing
3Adaptability or versatility
If PSTN is used for cloud-based calls, then legacy telephone number support is maintained, but additional services like video calling and OTT services cannot be provided
Solution Approach 1:
The system segments services into PSTN-dependent legacy services and IP-native modern services. Video calling and OTT services are routed exclusively through IP-based direct connections, eliminating PSTN traversal and associated costs. Legacy voice services maintain PSTN compatibility when necessary, optimizing the balance between service versatility and cost efficiency
4Productivity
If cloud-based interconnection is implemented without PSTN, then service efficiency is improved, but compatibility with legacy systems may be compromised
Solution Approach 1:
The session border controller acts as a compatibility intermediary that translates between IP-based cloud protocols and PSTN protocols. This intermediary enables seamless interaction between modern cloud services and legacy systems, maintaining compatibility while allowing efficient IP-based routing for cloud-to-cloud connections

AI summary
Novel tools and techniques are provided for implementing cloud-based voice calling service, video calling service, and/or over-the-top (“OTT”) services. In various embodiments, with a unified communications and collaboration interconnection (“UCCI”) interconnection established between separate hyperscalers or communication service providers that have separate administrative domains, Internet Protocol (“IP”) based communications services may be instantiated between a first user device or a first telephone number (or call identifier (“ID”)) via a first hyperscaler and a second user device or a second telephone number (or call ID) via a second hyperscaler, without touching or traversing the public switched telephone network (“PSTN”). By bypassing the PSTN, not only can cloud-based voice calling services be implemented or established over the UCCI, but cloud-based video calling services and OTT services may also be instantiated, with the OTT services being instantiated during either the cloud-based voice calling services or the cloud-based video calling services.
