Terminal Device Communication Mode Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems do not adequately utilize multiple communication modes, leading to inefficient user operations and potential missed calls due to inappropriate selection between normal call origination and ring-back tone (RBT) call origination.
Innovation Solution
A terminal device that acquires and stores reference times and call origination data to selectively choose between normal call origination and RBT call origination based on user operations and communication partner activity, ensuring appropriate mode selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If normal call origination mode is used, then communication is started after user operation is performed, ensuring user awareness, but communication cannot be started promptly
Solution Approach 1:
The system dynamically switches between normal call origination mode and ring-back tone mode based on real-time detection of user operations. The controller monitors for user operations within a predetermined time window and adapts the communication mode accordingly, allowing the system to be both prompt and aware of user intentions.
Solution Approach 2:
The system performs preliminary detection of user operations within a predetermined time window before initiating communication. By detecting user operations in advance and using this information to select the appropriate communication mode, the system ensures both prompt startup and user awareness without requiring the user to explicitly choose a mode.
2Loss of time
If ring-back tone mode is used, then communication is started promptly without user operation, but communication may start without user knowledge
Solution Approach 1:
The system dynamically adapts the communication mode based on detected user operations. When user operations are detected within the predetermined time window, the system switches to normal call origination mode to ensure user awareness. When no user operations are detected, it uses ring-back tone mode for prompt startup, thus dynamically balancing both requirements.
Solution Approach 2:
The controller continuously monitors for user operations and uses this feedback information to determine which communication mode to employ. This feedback mechanism ensures that the system responds to user intentions while maintaining prompt communication startup, resolving the contradiction between user awareness and communication speed.
3Reliability
If manual selection of communication mode is required, then appropriate mode can be chosen, but user operation complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting user operations and selecting the appropriate communication mode without requiring manual user input. The controller monitors for user operations within a predetermined time window and autonomously determines whether to use normal call origination mode or ring-back tone mode, simplifying user operations while maintaining appropriate mode selection.
Solution Approach 2:
The system uses feedback from user operation detection to automatically select the appropriate communication mode. By continuously monitoring for user operations and adapting the mode based on this feedback, the system eliminates the need for manual mode selection while ensuring appropriate communication initiation, thus improving both ease of operation and reliability.
Data Source
AI summary
An acquisition unit acquires a reference time that is a reception time when a signal was received from another terminal or a call origination time when the other terminal device transmitted a signal. A storage stores a call origination time when a signal was transmitted to the other terminal device. A controller selects, by referring to the reference time acquired by the acquisition unit and the call origination time stored in the storage, a first communication mode in which communication is started after a predetermined user operation is performed in the other terminal device or a second communication mode in which communication is started even when the predetermined user operation is not performed in the other terminal device. A communication unit transmits a signal to the other terminal device in accordance with the communication mode selected by the controller.
