Solution Overview

Problem

In PTT communication, the display of a 'no reply' signal is not effectively managed after the communication application ends, leading to inconvenience in notifying users of unresponded start notifications and potential unnecessary displays of absent signals.

Innovation Solution

A communication apparatus and method that store data in a storage region accessible by other programs, allowing the display of 'no reply' signals even after the PTT application ends, and suspend the display conditionally based on user instructions, ensuring proper notification and avoiding unnecessary displays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the PTT application stores 'no reply' signal data in its local storage region, then the display of absent signals can be maintained after the application ends, but other programs cannot access or manage this display data

Engineering Contradiction:
Improvenotification reliabilityVSAvoiddata accessibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces a mediator program that acts as an intermediary between the PTT application's local storage and the display system. This mediator reads the absent signal data from the PTT application's storage region and manages the display, allowing other programs to access and control the display without directly accessing the PTT application's protected storage region.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of information

If the display of absent signals is continuously shown, then users are notified of all unresponded notifications, but unnecessary displays appear when the user is already aware or when the application is actively running

Engineering Contradiction:
Improvenotification informationVSAvoiduser experience
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent implements dynamic display control where the display of absent signals is adjusted based on the operational state of the PTT application. When the application is actively running or when the user has already viewed the notification, the display is automatically suspended or removed, preventing unnecessary notifications while ensuring important information is conveyed when relevant.

Inventive Principle:
Principle #15Dynamics

3Productivity

If the PTT application automatically ends without user input, then the system responds quickly to unresponded notifications, but the display of absent signals cannot be managed after the application terminates

Engineering Contradiction:
Improvesystem response efficiencyVSAvoidabsent signal notification
Core Design Contradiction:
ProductivityVSLoss of information

Solution Approach 1:

The patent implements preliminary action by having the PTT application store absent signal data in its local storage region before terminating. This ensures that even though the application ends quickly without user input, the notification data is preserved and can be displayed by the mediator program, preventing information loss while maintaining system efficiency.

Inventive Principle:
Principle #10Preliminary action

AI summary

In a case where a PTT start notification is received at a communication part 102, a PTT application for executing processing concerning PTT communication is started up, and an instruction for starting the PTT communication is not input to a key input part 103 for a predetermined time, the PTT application automatically ends and predetermined flag data fg is stored in an external data storage region AR1. After that, when the PTT application is not started up, a notification of reception of an absent signal indicating no reply to the PTT start notification is reported based on the flag data fg stored in the external data storage region AR1. Further, in an automatic reply mode, when PTT communication which automatically started in response to the PTT start notification ends, the reception of a PTT communication start notification of no reply, that is, reception of an absent signal, is suitably reported to a user based on presence/absence of transmission of information from the communication part 102 in the communication apparatus itself at a and input of an instruction at the key input part 103.
