Mobile Conferencing Dial-In Number Substitution

Solution Overview

Problem

Users participating in teleconferences from abroad often face high overage fees and roaming charges due to dialing local dial-in numbers provided in conference invitations, which are not suitable for their current location.

Innovation Solution

A mobile conferencing system that automatically determines and uses a proper dial-in number based on the user's current location, replacing the provided dial-in number with a locally optimal alternative to minimize international calling costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If users dial the provided dial-in number from abroad, then they can join the teleconference, but they incur high international long-distance and roaming charges

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The system provides different dial-in numbers based on the user's geographic location. When a user travels abroad, the system automatically detects their location and provides a local dial-in number for that country instead of the home country number, making the communication cost-effective for the local context while maintaining the ability to join the same teleconference

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The system changes the dial-in number parameter based on the user's location. By detecting that a user is abroad through GPS or network information, the system automatically substitutes the original dial-in number with an alternative number appropriate for the user's current country, thereby reducing international calling charges

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If the system provides a single dial-in number in the invitation, then it simplifies the conference setup, but it causes high costs for users traveling abroad

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSLoss of energy

Solution Approach 1:

The system automatically detects user location and selects the appropriate dial-in number without requiring manual configuration or user intervention. The mobile device or server automatically substitutes the correct number based on detected geographic information, making the cost-optimization process self-service and transparent to the user

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system pre-configures multiple dial-in numbers for different countries and stores them in advance. When a user receives a conference invitation, the system has already prepared location-specific alternatives, so no additional setup is needed at the time of use— the correct number is automatically selected based on real-time location detection

Inventive Principle:
Principle #10Preliminary action
