Serverless Cloud Audio Broadcast via Telephony
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional audio broadcast systems face challenges in large-scale adoption due to complexity, requiring users to be conversant with specific software and equipment, leading to difficulties in reaching diverse user bases and high costs associated with proprietary hardware.
Innovation Solution
An event-driven serverless cloud computing platform integrates with a cloud communications platform to initiate and manage telephone calls, allowing for real-time audio streaming and broadcasting to multiple devices via a single call-in number, using protocols like RTMP and WebRTC, and enabling easy user input and subscription processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional PBX telephone systems with proprietary hardware are used, then telephony operations can be performed, but the system complexity and cost increase significantly
Solution Approach 1:
The patent extracts the core telephony operations from local PBX hardware and relocates them to a cloud communications platform. The local hardware is minimized to simple desk phones or softphones, while all complex telephony functions (call routing, switching, management) are performed remotely in the cloud, eliminating the need for complex on-premises hardware.
Solution Approach 2:
The patent introduces a cloud communications platform as an intermediary between users and the telephone network. This platform acts as a mediator that handles all complex telephony operations, allowing users to access full PBX functionality through simplified interfaces without requiring local hardware complexity.
2Device complexity
If cloud-based CPaaS is used to minimize local hardware, then hardware complexity is reduced, but user sophistication requirements increase
Solution Approach 1:
The patent makes the cloud communications platform universally accessible through multiple interfaces including desk phones, softphones, and web browsers. This multi-functionality allows users with varying levels of technical sophistication to access the same telephony services through their preferred device type, eliminating the need for specialized knowledge.
Solution Approach 2:
The system provides automated call routing, notification delivery, and broadcast management without requiring user configuration or technical knowledge. Users simply dial in or receive calls automatically, and the cloud platform handles all complex operations including audio streaming distribution, call setup, and teardown automatically.
3Reliability
If audio broadcast is delivered via traditional methods, then audio can be transmitted, but scalability and cost-effectiveness decrease
Solution Approach 1:
The patent segments the audio broadcast delivery by initiating separate telephone calls to each subscriber while simultaneously delivering the audio stream through the cloud platform. This segmentation allows the system to scale to any number of subscribers by simply provisioning additional call resources in the cloud, rather than requiring a single complex broadcast infrastructure.
Solution Approach 2:
The patent adds a temporal dimension to audio broadcast by implementing both real-time streaming for live broadcasts and on-demand playback for recorded content. The cloud platform stores audio streams and can deliver them either as live streams or as on-demand playback, enabling flexible broadcast scheduling and replay capabilities that scale independently of the number of subscribers.

AI summary
An audio broadcast system may include communications devices, a cloud communications platform in communication with the communications devices, and an event-driven serverless cloud computing platform in communication with the communications devices and the cloud communications platform. The event-driven serverless cloud computing platform may be configured to provision resources from the cloud communications platform to initiate telephone calls respectively for the communications devices, and simultaneously broadcast an audio stream to the communications devices respectively via the telephone calls.
