Communication Terminal Automatic Call Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in selecting between videophone and voice phone for communication, as they need to manually determine compatibility and preference for each contact, leading to unnecessary calls and increased user load.
Innovation Solution
A communication terminal apparatus with a storage unit for pre-storing communication preferences and a selection unit that automatically selects between videophone and voice phone based on stored information, allowing for seamless switching between the two modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the user manually determines compatibility and selects communication method for each contact, then the user can control communication preferences, but the user burden and operation complexity increase
Solution Approach 1:
The communication terminal automatically determines communication compatibility and selects communication methods based on stored contact information, eliminating the need for manual user intervention. The system serves itself by autonomously querying compatibility databases and making selection decisions, thereby reducing user burden and operational complexity.
Solution Approach 2:
The system pre-stores communication control information including compatibility data and user preferences for each contact in advance. When a call is initiated, the system retrieves and utilizes this pre-stored information to automatically determine the appropriate communication method, eliminating the need for real-time manual determination.
2Extent of automation
If the user pre-registers attributes for each contact, then automatic determination is enabled, but the setup time and information input increase
Solution Approach 1:
The system utilizes existing address book information and shared communication control information databases that are already available in the communication ecosystem. By leveraging these existing universal resources, the system enables automatic determination without requiring users to input new information, thereby achieving automation without increasing setup time.
Solution Approach 2:
The system introduces a shared communication control information database that acts as an intermediary, storing compatibility information and user preferences centrally. This mediator enables automatic determination by providing pre-configured data that the terminal can query, eliminating the need for each user to manually register attributes for every contact.
3Productivity
If the system automatically selects communication method, then unnecessary calls are prevented, but the system complexity increases
Solution Approach 1:
The system queries shared communication control information databases to retrieve compatibility data and user preferences, using this feedback information to automatically determine the appropriate communication method. This feedback mechanism enables the system to make informed selections that prevent unnecessary calls while maintaining relatively simple system architecture by leveraging existing information infrastructure.
Data Source
AI summary
A storage unit stores name, phone number, and a videophoning flag indicating whether to preferentially use a videophone or not in association with each person to communicate with. A CPU refers to the videophoning flag associated with a person when controlling a communication unit to make a call to that person, and determines whether to prioritize a voice phone or to prioritize the videophone. The CPU controls the communication unit to make a call by the videophone if the videophone is prioritized, or to make a call by the voice phone if the voice phone is prioritized. When a call from a person is received by the videophone, the CPU refers to the videophoning flag of that person, and permits communication by the videophone if the videophone is prioritized or does not permit communication by the videophone if the voice phone is prioritized.
