Automatic TTY-Mode Selection in Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile devices require manual and cumbersome processes to set and switch between TTY-modes for teletypewriter communication, which can be inconvenient for users, especially those who are deaf or hearing impaired, as they need to navigate complex menus for call initiation and management.
Innovation Solution
A method and apparatus that automatically sets a user equipment (UE) into a plurality of TTY-modes through user-settable entries in the address book or other applications, allowing for seamless TTY-mode selection and switching during call initiation and receipt, using a computer-readable medium to execute processes that associate phone numbers with specific TTY-modes and audio settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual menu selection is used to set TTY-mode, then the device can be configured for TTY communication, but the operation becomes cumbersome and inconvenient
Solution Approach 1:
The patent applies preliminary action by pre-configuring TTY-mode settings in the address book before the call is made. When a user enters a phone number, the system automatically retrieves and applies the pre-set TTY-mode configuration, eliminating the need for manual menu navigation during call initiation.
Solution Approach 2:
The system performs self-service by automatically detecting when TTY-mode should be activated based on the called party's profile stored in the address book. The device autonomously configures itself without requiring user intervention in the menu system, making the process invisible and automatic.
2Ease of operation
If automatic TTY-mode selection is implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent leverages the existing address book structure to serve multiple functions: storing contact information, TTY-mode preferences, and audio settings. By making the address book multi-functional, the system avoids adding separate complex configuration mechanisms while still achieving automatic TTY-mode selection.
Solution Approach 2:
The system merges the TTY-mode configuration functionality with the existing address book and calling infrastructure. Instead of creating a separate configuration system, the patent integrates TTY settings into the address book entries and uses the existing call initiation logic to automatically apply these settings, thereby reducing overall system complexity.

AI summary
Disclosed is a method for allowing a user to select, from a plurality of TTY-modes, one TTY-mode to associate with one phone number. The associated TTY-mode will be used for either incoming or outgoing calls using that phone number. Further disclosed are a plurality of TTY-modes to associate with individual phone numbers, and, a selectable set of default TTY-modes to use if no TTY-mode is associated with a particular phone number. Selectable audio modes, assoeiable with phone numbers or with TTY-modes, is also discussed.
