IVR Resource Pooling for Switching Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive Voice Response (IVR) systems face inefficiencies in resource utilization due to increasing demands from sophisticated telecommunication services, leading to resource bottlenecks and high costs, especially in speech processing and software complexity.
Innovation Solution
The IVR system is designed to be accessed by multiple switching systems, with exclusive control and user data interfaces, allowing for better resource management and distribution. This includes methods to handle resource bottlenecks, such as halting applications if resources are unavailable or reserving resources before processing, ensuring efficient utilization and avoiding delays.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If IVR resources are centralized in a single system, then resource utilization efficiency improves, but system complexity and difficulty of managing multiple switching systems increases
Solution Approach 1:
The patent segments the IVR system into multiple independent IVR servers (first IVR server, second IVR server) that can be separately managed and operated. Each server handles specific switching systems, dividing the complex centralized system into manageable modules while maintaining overall resource sharing capabilities
Solution Approach 2:
The patent implements universal IVR resources that can serve multiple switching systems simultaneously. The IVR servers provide common speech processing, text-to-speech conversion, and speech recognition capabilities to different switching systems, allowing one resource to perform multiple functions for different users
2Device complexity
If IVR resources are distributed to multiple switching systems, then system complexity decreases, but resource utilization efficiency deteriorates due to duplication
Solution Approach 1:
The patent merges the IVR resources of multiple switching systems into shared IVR servers. Speech processing resources, text-to-speech engines, and speech recognition systems are combined into common pools that multiple switching systems can access, eliminating duplication while maintaining simplified system architecture
3Adaptability or versatility
If speech processing resources are increased to handle sophisticated services, then service capability improves, but costs and computing power requirements increase
Solution Approach 1:
The patent implements continuous resource sharing where speech processing resources are continuously utilized by multiple switching systems. The IVR servers maintain persistent connections with multiple switching systems, ensuring that computing power and storage space are continuously productive rather than idle, thereby reducing total resource requirements

AI summary
The invention relates to an interactive voice response (IVR) system supplying functions and resources to services encompassing interactive voice response or output of announcements and three methods for dealing with resource bottlenecks of the IVR system. The IVR system supplies a pool of resources to several switching systems. Virtual, individually assigned IVR systems are created from the perspective of the switching systems by allocating the control interfaces and user data interfaces of the IVR system in an exclusive, disjunctive manner to the switching systems. Resource bottlenecks can be prevented when several switching systems access the IVR system by rejecting jobs for which the required resources cannot be reserved or by aborting jobs creating too substantial delays during processing due to the wait for resources. The invention has the advantage of efficiently utilizing the resources supplied by the IVR system.
