IP Text Relay Caller ID Pass-Through for Hearing Impaired Users
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications systems for the hearing impaired, such as IP Relay services, do not provide caller ID functionality, leaving hard of hearing users unaware of the identity of incoming callers until they reveal themselves, and do not offer functional equivalency in voice communication.
Innovation Solution
A system and method that uses IP communication to transmit and receive voice and text, allowing the caller ID of the calling party to be displayed on the hearing impaired user's device, rather than the relay service provider's ID, through a transceiving device connected to both phones, enabling text transcription and caller ID pass-through.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If IP Relay services are used for hearing impaired users, then text communication capability is provided, but caller ID functionality is not provided
Solution Approach 1:
The patent uses the relay service provider's system as an intermediary to transmit both voice communications and caller ID information from the hearing caller to the hearing-impaired user. The relay system mediates the information flow, capturing caller ID data at the incoming leg and relaying it through to the outgoing leg, thereby preserving identity information without requiring direct modification of the end-user devices.
Solution Approach 2:
The relay service system is enhanced to perform multiple functions: traditional text transcription of voice communications plus the additional function of caller ID transmission. By making the relay system multi-functional, it can handle both captioning and identity information delivery through the same infrastructure, reducing the need for separate specialized systems.
2Adaptability or versatility
If traditional relay services are used, then communication assistance is provided, but functional equivalency to voice communication is not achieved
Solution Approach 1:
The patent segments the communication information into distinct components: voice transmission, text captioning, and caller ID delivery. Each component is handled separately through appropriate channels (voice over IP, text relay, and metadata transmission), allowing the hearing-impaired user to receive all essential communication elements that would be present in a direct voice call, thereby achieving functional equivalency.
Solution Approach 2:
The relay service acts as a mediator that reconstructs the complete communication experience for hearing-impaired users by gathering information from the caller side (voice and caller ID) and delivering it through appropriate channels (text and metadata), making the communication functionally equivalent to direct voice communication despite the intermediary involvement.
3Loss of information
If relay service provider's caller ID is displayed, then system identification is provided, but user identity preservation is compromised
Solution Approach 1:
The relay service provider's system serves as an intermediary that captures the authentic caller ID information from the incoming call leg and forwards it through to the outgoing call leg without modification. This intermediary approach preserves the true identity of the calling party while maintaining the privacy and security architecture of the relay service, as the provider handles the identity transmission through controlled channels rather than exposing raw caller information.

AI summary
IP text relay or phone captioning is described herein, to facilitate communication through the use of traditional phone or VOIP or internet telephone system between people of hearing impaired and those who can hear. This service and device will enable users to communicate with users of hearing via assistance of an operator who will transcribe the call, while also receiving the Caller ID of the calling party and not the relay center.
