Mobile Device Line Selection via Audio Prompts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices lack an efficient method to allow users to select and initiate outgoing calls on specific communication lines, which can lead to incorrect billing and tracking issues for business and personal communications.
Innovation Solution
A mobile device system that includes a call initiation detection module, audio prompt module, line selection input module, and voice recognition module to guide users in selecting the appropriate communication line for outgoing calls, using audio and voice prompts to facilitate line selection based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication lines are associated with a mobile device, then the device can support both business and personal communications, but the device complexity increases due to the need to manage and select between multiple lines
Solution Approach 1:
The system performs preliminary action by automatically detecting the type of call being placed (local or long distance) and pre-selecting the appropriate communication line before the user needs to make the call. The line selection is determined in advance based on the call characteristics, reducing the need for manual intervention during the call placement process.
Solution Approach 2:
The system enables self-service by allowing the mobile device to automatically manage line selection based on predefined criteria. The device monitors call parameters and autonomously determines which communication line should be used, eliminating the need for complex user intervention in the line management process.
2Ease of operation
If automatic line selection is implemented based on call type, then the ease of operation improves, but the reliability may worsen if the wrong line is selected due to automated decision-making
Solution Approach 1:
The system incorporates feedback mechanisms where the mobile device monitors the actual call parameters (such as destination number characteristics) and compares them against predefined criteria. Based on this feedback, the system dynamically adjusts line selection to ensure accuracy, and can provide user confirmation opportunities when uncertainty arises.
Solution Approach 2:
The system changes parameters by monitoring call characteristics such as destination number format, network type, and call duration. These parameter changes trigger appropriate line selection decisions based on stored profiles and criteria, enabling the system to adapt to different calling scenarios while maintaining high reliability through data-driven decision-making.

AI summary
Devices and methods for placing a call from a mobile device on one of a plurality of communication lines accessible at the mobile device are disclosed herein. The mobile device is configured to associate either beeps or musical tones with a request for a line selection. When a call is initiated at the mobile device the beeps or musical tones are outputted in combination with a visual prompt on a display to request a line selection. A user input is received identifying the line selection in response to the outputting, a selected one of the plurality of communication lines accessible at the mobile device is identified from the user input; and a communication module is operated to place the call on the selected communication line.
