IVR Multimedia Stream Delivery via QoS Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive voice response (IVR) systems struggle to effectively deliver multimedia content streams that maintain quality of service (QoS) across telecommunications terminals, as existing technologies fail to adaptively manage the transmission of audio and video components based on real-time network conditions.
Innovation Solution
The IVR system employs extensions to the Voice eXtensible Markup Language (VXML) standard, allowing telecommunications terminals to inform the IVR system of QoS levels, enabling intelligent delivery of multimedia content streams by prioritizing components that maintain or improve QoS, suspending or resuming audio or video components as necessary based on bandwidth, latency, and error rate thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multimedia content streams are delivered to telecommunications terminals, then the quality and richness of the multimedia experience is improved, but the network bandwidth consumption increases and quality of service may degrade
Solution Approach 1:
The multimedia content stream is segmented into multiple components (audio, video, subtitles, etc.). The IVR system selectively delivers only necessary components based on terminal capabilities and network conditions, avoiding transmission of unnecessary data and reducing bandwidth consumption while maintaining service quality.
Solution Approach 2:
The system dynamically adjusts the delivery of multimedia components based on real-time network conditions and terminal capabilities. The IVR system can suspend or resume specific components (audio, video) as network conditions change, optimizing bandwidth usage while maintaining acceptable quality of service.
2Reliability
If multiple components of multimedia content streams are transmitted simultaneously, then the completeness of the content is improved, but the network latency and error rate increase
Solution Approach 1:
The content is divided into independent components that can be delivered separately. The IVR system determines the minimum necessary components for acceptable service and delivers only those, reducing transmission latency while maintaining content completeness at an acceptable level.
Solution Approach 2:
The system extracts and delivers only the essential components needed for basic service functionality. Non-essential components are omitted or delivered on-demand, reducing overall transmission time and latency while maintaining core service completeness.
3Reliability
If the IVR system monitors and adapts to real-time network conditions, then the quality of service is maintained, but the system complexity increases
Solution Approach 1:
The terminal provides feedback to the IVR system about its capabilities and received signal quality. The IVR system uses this feedback to dynamically adjust component delivery, maintaining quality of service without requiring complex monitoring infrastructure.
Solution Approach 2:
The terminal autonomously determines which components it can receive based on its capabilities and network conditions, then requests only those components from the IVR system. This self-service approach reduces the complexity of centralized monitoring and control while maintaining service quality.

AI summary
A method and apparatus are disclosed for intelligently delivering components of a multimedia content stream (e.g., audio component, video component, etc.) to a telecommunications terminal based on the quality of service (QoS) for transmissions received at the terminal. The illustrative embodiment is disclosed in the context of an interactive voice response system, but is applicable in a wide variety of other telecommunications systems and applications.
