Communication Terminal Session Transfer via Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video conference systems face challenges in balancing handy operation with improved communication quality, as mobile stations have small displays making it difficult to effectively communicate, while larger communication terminals are less convenient for initiating sessions.
Innovation Solution
A communication system that allows users to join sessions between terminals, enabling seamless transfer and switching between mobile stations and larger communication terminals, using a relay device and communication management system to manage sessions and authentication, and display information centrally, facilitating both convenient operation and enhanced communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile station with a small display screen is used to initiate communication, then handy operation is improved, but communication quality deteriorates
Solution Approach 1:
The system uses a mobile station as an intermediary device to initiate communication sessions. The mobile station with small display enables handy operation for session initiation, while the actual communication occurs through a separate communication terminal with large display that provides high communication quality. The mobile station acts as a mediator that transfers control to the communication terminal.
2Reliability
If a communication terminal with a large display screen is used to initiate communication, then communication quality is improved, but ease of operation deteriorates
Solution Approach 1:
The system segments the communication function into two distinct roles: a mobile station for session initiation and control, and a communication terminal for actual communication execution. This segmentation allows each device to specialize in its strengths - the mobile station provides ease of operation for initiating sessions, while the communication terminal provides communication quality through its large display.
3Adaptability or versatility
If session transfer is implemented from one terminal to another, then adaptability is improved, but device complexity increases
Solution Approach 1:
The system implements session transfer through a communication management system that acts as an intermediary between terminals. The management system handles the complexity of session transfer, authentication, and control switching, while individual terminals maintain relatively simple functionality. This mediator approach enables adaptability for session transfer without significantly increasing terminal device complexity.

AI summary
A communication terminal (10, 70a, 70d, 90a), a method of communication, and a carrier means carrying computer readable code for controlling a computer to carry out the method. The communication terminal (10, 70a, 70d, 90a) and the method includes outputting (S23, S147, S222, S302) terminal identification information identifying a communication terminal (10, 70a, 70d, 90a), receiving (S31, S150) external terminal identification information identifying an external communication terminal, the external terminal identification information being sent from the external communication terminal through a communication management system (50) to a destination address of the communication terminal (10, 70a, 70d, 90a) indicated by the terminal identification information, and transmitting (S149, S222, S301), when requesting to start communication with a counterpart communication terminal, the received external terminal identification information to the communication management system (50), instead of the terminal identification information of the communication terminal (10, 70a, 70d, 90a).
