Mobile Device Voice Delivery Control via Network Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices lack the capability to seamlessly switch from a cellular network to a wireless network for voice over Internet protocol (VoIP) communications when the cellular signal is poor, without considering user-specific security requirements, leading to battery drain and potential security risks.
Innovation Solution
A method that creates a user profile specifying switching thresholds and security levels for contacts, allowing the device to monitor cellular signal strength, detect nearby wireless networks, and authorize switching to VoIP based on the security level associated with the communicating party, ensuring secure or unsecure network usage as required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile device continues to ping the cellular network for service when signal is lost, then the device maintains network connectivity, but the battery drains at a high rate
Solution Approach 1:
The mobile device autonomously monitors its own cellular signal strength and automatically switches to Wi-Fi calling when cellular signal falls below a threshold, without requiring continuous user intervention or manual network selection
Solution Approach 2:
The system changes the network communication parameter from cellular network to Wi-Fi network based on signal strength threshold, allowing the device to adapt to changing signal conditions and preserve battery life
2Reliability
If the user switches to voice over Internet protocol over a wireless network when cellular signal is poor, then voice communications can be maintained, but security requirements may be compromised
Solution Approach 1:
The system checks the user profile and security requirements before switching to Wi-Fi calling, using feedback from the profile data to determine whether the call should be routed over Wi-Fi or kept on cellular network
Solution Approach 2:
The user profile is pre-configured with security requirements and network preferences before the call occurs, allowing the system to make informed routing decisions without compromising security
3Ease of operation
If the mobile device provides automatic network switching capability, then seamless voice communication is achieved, but device complexity increases
Solution Approach 1:
The mobile device integrates multiple network interfaces (cellular and Wi-Fi) and a unified calling system that can operate over either network, providing multi-functionality without requiring separate systems for each network type

AI summary
A method, system and computer program product for controlling the delivery of voice communications. A profile is created for the user of a mobile device that specifies the thresholds for switching between a cellular network and a wireless network to conduct voice communications as well as stores a list of contacts and associated security levels. If the signal strength of the cellular radio signal is below a threshold, then the mobile device detects one or more wireless networks that are in the area of the user of the mobile device. The profile of the user of the mobile device is then checked to determine if the mobile device is authorized to switch to one of the detected wireless networks to deliver voice communications based on a security level associated with the party communicating with the user. In this manner, the user is able to control the delivery of voice communications.
