PTT Missed Call Voice Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication terminals for Push To Talk (PTT) communication only notify receivers of missed calls with originator information and time, without providing the reason for the call, limiting user understanding.
Innovation Solution
A mobile communication terminal with a PTT communications module, voice processor, buffering unit, missed call determining unit, and storage that buffers and stores the voice of the originator during a missed call, allowing users to output the voice when confirming missed call information, enabling users to determine the reason for the call.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If only originator information and time are stored in missed call information, then storage space is saved and device complexity is reduced, but the receiver cannot know the reason why the originator requested a PTT telephone call
Solution Approach 1:
The voice message is buffered and stored in advance when the PTT call is received, before the user needs to check missed call information. This preliminary action ensures that when the user reviews missed calls, the voice message is already available, providing complete information without requiring complex real-time processing.
Solution Approach 2:
Instead of storing the entire voice call data, the patent stores a copied version of the voice message in a buffered format. This copy contains sufficient information to convey the originator's purpose while occupying minimal storage space, balancing information completeness with storage efficiency.
2Loss of information
If voice message is buffered and stored in missed call information, then the receiver can understand the purpose of the call, but storage space is consumed and device complexity increases
Solution Approach 1:
The patent uses a buffering mechanism that stores voice data in a lightweight, temporary format rather than preserving the full high-fidelity audio recording. This approach consumes minimal storage space while still providing sufficient information for the user to understand the call's purpose, treating the stored voice data as a functional equivalent rather than a permanent archive.
3Ease of operation
If traditional missed call information is used, then device complexity is low, but the receiver cannot determine the reason for the missed call
Solution Approach 1:
The patent introduces a voice message buffer as an intermediary element between the PTT call reception and the missed call information display. This buffer mediates by converting the audio signal into a storable format that can be retrieved and played back, bridging the gap between receiving a call and providing meaningful missed call information without requiring complex integrated processing.

AI summary
The present invention relates to a mobile communication terminal for Push To Talk (PTT) and a method for processing missed call information thereof, which allows a receiver to check why an originator requested the PTT telephone call during the absence of the receiver through missed call information. The missed call information includes the voice of the originator requesting the PTT call, and the voice of the originator is output when confirmation of the missed call information is requested.
