Communication Control System for Signal Loss Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, users of transmitting terminals face challenges in identifying which parts of voice or video signals have been lost during transmission, hindering smooth communication between terminals.
Innovation Solution
A communication control system that includes a signal transmitting unit, an acquisition unit to gather response information, a specifying unit to identify arrival and lost signals, and a display unit to show reception status on the transmitting terminal, allowing users to understand signal reception at the receiving terminal and potentially retransmit lost signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication system transmits voice or video signals from transmitting terminal to receiving terminal, then communication function is provided, but signal loss occurs in the communication line causing incomplete reception
Solution Approach 1:
The receiving terminal generates response information indicating which transmission signals were successfully received and transmits this feedback to the transmitting terminal. The transmitting terminal uses this feedback to identify lost signals and retransmit them, creating a closed-loop system that improves reliability by correcting signal loss based on reception status feedback.
2Loss of information
If the transmitting terminal retransmits lost signals, then communication completeness is improved, but the transmitting terminal cannot identify which signals were lost without response information
Solution Approach 1:
The receiving terminal provides precise measurement of reception status through response information that explicitly indicates which transmission signals were successfully received. This feedback enables the transmitting terminal to accurately identify lost signals by comparing the transmitted signal list with the received confirmation list, achieving precise detection of reception status.
3Reliability
If the system monitors and tracks signal reception status, then communication reliability is improved, but system complexity increases due to additional monitoring and feedback mechanisms
Solution Approach 1:
The system implements a feedback mechanism where the receiving terminal generates and transmits response information indicating received signals. This approach improves reliability by enabling loss detection and retransmission while maintaining relatively simple system complexity, as the feedback mechanism uses straightforward signal comparison rather than complex monitoring infrastructure.
4Loss of information
If response information is transmitted from receiving terminal to transmitting terminal, then lost signal identification is enabled, but additional communication overhead is introduced
Solution Approach 1:
The system extracts only the essential information needed for loss detection - a confirmation list indicating which transmission signals were successfully received. By transmitting only this extracted relevant information rather than complete signal data or detailed reception status reports, the system enables effective loss detection while minimizing additional communication overhead.

AI summary
Provided is a communication control system that controls communication between a transmitting terminal and a receiving terminal, including a signal transmitting unit that transmits a transmission signal being a voice signal or a video signal from the transmitting terminal to the receiving terminal, an acquisition unit that acquires response information specifying an arrival signal being a signal received by the receiving terminal among the transmission signal from the receiving terminal, a specifying unit that specifies the arrival signal or a lost signal being a signal not received by the receiving terminal among the transmission signal based on the transmission signal and the response information, and a display unit that displays reception status identification information capable of identifying the arrival signal or the lost signal on the transmitting terminal.
