Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless packet networks in telecommunication networks disconnect links if there is no data transmission for a certain period, causing delays in real-time text data transmission for IP-Relay and IP-CTS services, which are critical for effective communication with deaf and hard-of-hearing individuals.
Innovation Solution
Generating and sending dummy text data via the wireless packet network before resources are released, ensuring continuous transmittable status without releasing wireless resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If wireless packet networks release wireless resources when no data transmission occurs for a pre-set period, then wireless resource efficiency is improved, but transmission delay increases for real-time text data
Solution Approach 1:
The system performs preliminary action by sending dummy text data before the wireless resources are actually released. This keeps the wireless connection alive and prevents resource release, ensuring that when real text data needs transmission, the connection is already established and no re-allocation delay occurs.
Solution Approach 2:
The invention maintains continuous useful action by periodically transmitting dummy text data to prevent the wireless connection from being released. This continuous transmission keeps the wireless resources allocated and the connection active, eliminating interruptions and delays in real-time text data transmission.
2Productivity
If wireless resources are released to save limited resources, then resource utilization is improved, but real-time transmission capability deteriorates
Solution Approach 1:
Dummy text data acts as an intermediary element that maintains the wireless connection without requiring actual communication content. This intermediary transmission prevents resource release while the system remains ready for real-time text data transmission, preserving both resource efficiency and transmission reliability.
3Loss of time
If the wireless connection is maintained active, then transmission delay is reduced, but wireless resource consumption increases
Solution Approach 1:
The system applies partial action by transmitting only minimal dummy text data just sufficient to maintain the connection without excessive resource consumption. This partial transmission is enough to prevent resource release while consuming minimal wireless resources, balancing connection maintenance with resource efficiency.

AI summary
The present invention relates to a method and a system for a real time transmission of transcribed voice data via a wireless packet network of a telecommunication network used by IP-Relay or IP-CTS for deaf and hard-of-hearing individuals. The invention provides a text relay service communication system for a real-time transmission of transcribed voice data via a wireless packet network, comprising a text data receiving part for receiving text data generated and sent by a call agent; a text data transmitting algorithm part for generating dummy text data when the text data receiving part has not received any text data from the call agent for a pre-determined time period; and a text transmitting part for transmitting the text data and the dummy text data via the wireless packet network.
