Wireless Device Text Session via Service Node Mediator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless phone devices have not been effectively integrated with captioning centers to provide an efficient audio/text interface for hearing impaired users, limiting their ability to communicate effectively through text messaging.
Innovation Solution
A wireless communication device is configured to visually prompt users to initiate text sessions, connect to a service node, and facilitate text sessions by placing multiple calls to enable the translation of text and audio messages, allowing seamless audio/text communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless phone devices are integrated with captioning centers to provide text messaging capability, then hearing impaired users can communicate effectively through text, but the device complexity increases due to multiple call setup procedures
Solution Approach 1:
The patent introduces a captioning center as an intermediary system between the wireless phone device and the called party. The device places a call to the captioning center, which then places a separate call to the called party and handles the text-to-audio conversion. This mediator approach allows the device to maintain simplicity while achieving text communication capability through the captioning center's processing power.
2Adaptability or versatility
If the device places a call to the service node and transfers the called number, then the text session can be established, but the call setup time increases due to multiple sequential calls
Solution Approach 1:
The device performs preliminary actions by first establishing a call to the service node and transferring the called number before the actual text communication begins. This preliminary setup phase prepares the service node to receive and process text messages, allowing the main text session to start more efficiently once the preliminary call is established.
3Adaptability or versatility
If the service node places a second call to the called number, then audio/text translation can be performed, but the system requires multiple simultaneous calls increasing connection management complexity
Solution Approach 1:
The service node acts as an intermediary that manages multiple simultaneous calls. It receives the first call from the user's device, places a second call to the called party, and coordinates the audio/text translation between these two separate connections. This intermediary approach centralizes the complexity of managing multiple calls in the service node rather than requiring the user's device to handle complex multi-call coordination.

AI summary
A wireless communication device is configured to visually prompt a user to initiate a text session, and to receive a text session request from the user including a called number. In response to the text session request, the device initiates the text session by placing a first call to a service node using a service node number, and transfers the called number to the service node over the first call. The service node then extends the text session by placing a second call to the called number. Once the text session is established, the device sends a first text message to the service node over the first call, and receives a second text message from the service node over the first call. The device then visually displays the second text message to the user.
