Telephony Switching System with Inverse Call Charge Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telephony communication technologies are inefficient in switching between basic and alternative telephony modes, leading to unequal utilization and increased call charges due to the lack of automatic switching based on the receiver's subscription status and communication conditions.
Innovation Solution
A method and apparatus that automatically determine whether to use basic or alternative telephony by sending a call connection request to the appropriate network based on the receiver's subscription status and communication readiness, and compute an inverse call charge to incentivize the use of alternative telephony by notifying users of potential cost savings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If manual selection of telephony mode is used, then system complexity is reduced, but switching efficiency and cost-effectiveness deteriorate
Solution Approach 1:
The system automatically determines the receiver's telephony subscription status and switches between basic and alternative telephony modes without requiring manual user input. The switching determination module autonomously selects the appropriate communication mode based on stored subscription information, enabling self-service operation that improves switching efficiency while maintaining simple user interaction.
Solution Approach 2:
The system pre-stores telephony subscription status information for multiple receivers in advance. When a call is initiated, the system quickly retrieves this pre-stored information to determine the appropriate telephony mode, eliminating the need for real-time queries and enabling rapid switching decisions without increasing system complexity.
2Loss of energy
If alternative telephony is used, then call charge is reduced, but service availability deteriorates when receiver is not subscribed
Solution Approach 1:
The system dynamically switches between alternative telephony and basic telephony modes based on the receiver's subscription status. When the receiver is subscribed to alternative telephony, the system uses this lower-cost mode; when not subscribed, it automatically switches to basic telephony to ensure service availability. This dynamic adaptation resolves the contradiction between cost reduction and service reliability.
Solution Approach 2:
The switching determination module acts as an intermediary that mediates between the caller and the receiver by selecting the appropriate telephony mode. It checks the receiver's subscription status and routes the call through alternative telephony when available (for cost reduction) or basic telephony when necessary (for reliability), thereby balancing both objectives.
3Productivity
If automatic switching based on receiver status is implemented, then call charge efficiency is improved, but device complexity increases
Solution Approach 1:
The switching determination module performs multiple functions: it retrieves receiver information, checks subscription status, determines the appropriate telephony mode, and initiates the call through the selected network. This multi-functional module consolidates what could be separate complex components into a single unit, improving call charge efficiency while minimizing the increase in device complexity.
Solution Approach 2:
The system uses pre-stored copies of receiver subscription status information to make switching decisions. Instead of querying the receiver's status in real-time, the system retrieves previously stored subscription data, which simplifies the switching process and reduces the complexity of real-time status verification while maintaining efficient call charge management.
4Ease of operation
If caller-only benefit model is used, then alternative telephony adoption by callers is improved, but overall utilization deteriorates
Solution Approach 1:
The system provides feedback to both callers and receivers about the telephony mode being used and the associated cost savings. By informing users about the benefits of alternative telephony and their subscription status, the system encourages receivers to subscribe to alternative telephony services, thereby improving overall utilization while maintaining ease of operation for callers.

AI summary
Disclosed is a method and an apparatus for providing an alternative telephony service which automatically switches an originating call between a basic telephony network and an alternative telephony network, and a method of inducing a caller or a receiver to subscribe to a service having a cheaper call rate by notifying the caller or the receiver of an inverse call charge which can be reduced according to whether telephony communication is performed using a basic telephony or an alternative telephony. Accordingly, it is possible to automatically connect the telephony communication using the basic telephony or the alternative telephony according to a telephony communication condition of the receiver, and thus reduce inconvenience due to a direct control of the receiver and first select a telephony communication scheme having a cheap call rate. Further, it is possible to more actively save a telephony communication call charge by naturally recommending the subscription and the use of the alternative telephony service through the notification of the inverse call charge to a non-subscriber or a non-user of the alternative telephony service.
