Inter-Carrier Call Routing via Software Platform Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing call routing systems between different public switched telephone network (PSTN) carriers experience high latency and infrastructure failures due to multiple hops through various provider networks, leading to a poor user experience.
Innovation Solution
Implementing a software platform that intelligently routes calls between user devices associated with the same Unified Communications as a Service (UCaaS) platform, reducing the number of hops by maintaining the call on the software platform and transmitting call information to carriers only for logging and billing purposes, thereby minimizing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If calls are routed through multiple provider networks and carriers, then carriers can perform logging and billing, but latency increases and user experience deteriorates
Solution Approach 1:
The patent segments the call routing process into two distinct parts: (1) media path routing directly between endpoints through the software platform, and (2) signaling path routing call information to carriers for logging and billing. This segmentation allows the media flow to bypass carrier networks while still enabling carriers to perform their functions through separate information exchange.
Solution Approach 2:
The software platform acts as an intermediary that establishes direct peer-to-peer media paths between endpoints while simultaneously serving as the interface for carriers to receive call information. This intermediary role allows carriers to perform logging and billing without being part of the actual media path, thus eliminating latency.
2Adaptability or versatility
If calls traverse through multiple hops across different carrier networks, then inter-carrier calling is enabled, but infrastructure complexity and failure points increase
Solution Approach 1:
The patent merges multiple carrier networks into a unified software platform environment where all endpoints are virtualized. Instead of maintaining separate physical infrastructure for each carrier, the software platform consolidates routing, switching, and management functions, reducing overall system complexity while maintaining inter-carrier calling capability.
Solution Approach 2:
The software platform creates virtual copies of carrier network functions within its environment. Rather than requiring physical connections between different carrier infrastructures, the platform replicates necessary routing and signaling functions virtually, eliminating the need for complex inter-carrier physical infrastructure.
3Reliability
If calls are routed through traditional carrier networks, then carriers maintain control over call routing, but the number of hops increases reducing call quality
Solution Approach 1:
The patent inverts the traditional routing model by allowing endpoints to establish direct media paths without carrier involvement, while carriers receive information about these calls afterward. Instead of carriers controlling the actual media flow, they control only the information flow for billing purposes, fundamentally reversing the traditional approach.

AI summary
A software platform supports multiple carriers, such as telephony carriers or public switched telephone network (PSTN) carriers, and routes calls between devices associated with different carriers without having to route the calls through the different carriers. The software platform establishes or maintains the calls between the devices associated with different carriers by transmitting a portion of call data associated with call record information to the respective carriers, and a portion of the call data associated with media and signaling information to the destination device.
