Call Redirection System for VoIP Cost Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users in office environments often prefer mobile phones for calls despite higher costs and lower audio quality compared to fixed-line office telephony systems, especially when VoIP-capable devices are available, leading to unnecessary roaming charges and lower call quality.
Innovation Solution
A system and method that detects a call initiation on a mobile phone and redirects it to a VoIP-capable device, such as a PC, using a body-worn device like a headset to connect the call over a more cost-effective and higher quality network, synchronizing mobile and office telephony information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users use mobile phones to initiate calls in office environments, then call convenience and accessibility are improved, but telephony costs increase and audio quality deteriorates
Solution Approach 1:
The patent introduces a call redirection system that acts as an intermediary between the mobile phone and the fixed-line telephony system. When a call is initiated on the mobile phone, the system detects the initiation and automatically redirects the call to the fixed-line office telephony system, allowing the mobile phone to serve as a remote control while the high-quality fixed-line system handles the actual call.
Solution Approach 2:
The patent replaces the mobile cellular network transmission mechanism with a fixed-line telephony or VoIP transmission mechanism. By substituting the mobile network path with a wired or IP-based network path, the system achieves lower costs and better audio quality while maintaining the user's ability to initiate calls from the mobile device.
2Ease of operation
If users use mobile phones to initiate calls, then call accessibility is improved, but audio quality deteriorates
Solution Approach 1:
The call redirection system serves as an intermediary that separates the call initiation function (performed by the mobile phone for accessibility) from the call transmission function (performed by the fixed-line system for quality). The system detects mobile call initiation and redirects it to the fixed-line telephony system, which provides superior audio quality.
Solution Approach 2:
The patent substitutes the mobile cellular transmission path with a fixed-line or VoIP transmission path. This replacement maintains the accessibility benefit of mobile initiation while achieving the audio quality of wired telephony systems, effectively replacing the inferior mobile audio path with a superior fixed-line path.
3Ease of operation
If users use mobile phones for calls while abroad, then call availability is improved, but roaming charges increase
Solution Approach 1:
The patent introduces a call redirection intermediary that detects when a mobile phone attempts to initiate a call and automatically redirects it to a fixed-line or VoIP system. This allows users to maintain call availability from their mobile device while avoiding mobile roaming charges by routing the actual call through cheaper fixed-line or IP networks.
Solution Approach 2:
The patent replaces the expensive mobile roaming network path with a cheaper fixed-line or VoIP network path. By substituting the cellular network transmission with a wired or IP-based transmission, the system maintains global call availability through the mobile device while achieving cost savings through alternative network infrastructure.
4Loss of energy
If organizations encourage use of fixed-line office telephony, then cost savings are achieved, but user preference and habit are reduced
Solution Approach 1:
The patent implements a self-service call redirection system that automatically detects mobile call initiations and redirects them to fixed-line telephony without requiring user action. The system serves itself by monitoring call initiation events and autonomously performing the redirection, eliminating the need for user education or behavioral change while achieving cost savings.
Solution Approach 2:
The patent substitutes the user's preferred mobile calling mechanism with an automatic redirection to fixed-line telephony. The system transparently replaces the mobile network path with a fixed-line path, achieving cost savings without requiring users to change their calling habits or preferences.
