Communication Apparatus Selective Acknowledgement Response Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems do not allow users to selectively send acknowledgement responses for acknowledgement requests, leading to unintended disclosure of transmission destination information to the source apparatus.
Innovation Solution
A communication apparatus with a determination unit that uses destination information to decide whether to send an acknowledgement response, and a response control unit to either send the response or transfer data to an external apparatus for user confirmation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication apparatus automatically responds to all acknowledgement requests, then the delivery confirmation function is improved, but the user's privacy is compromised due to unintended disclosure of transmission destination information
Solution Approach 1:
The patent implements dynamic control of acknowledgement response behavior by allowing users to set different response policies for different destinations in the destination book. The system transitions from a static automatic response mode to a dynamic selective response mode, where the response behavior adapts based on user-defined preferences for each destination, thus protecting privacy while maintaining delivery confirmation functionality.
2Reliability
If the communication apparatus sends acknowledgement responses to all transmission source apparatuses, then the delivery notification function is improved, but the device complexity increases due to need for user selection mechanisms
Solution Approach 1:
The patent applies preliminary action by having users pre-configure their acknowledgement response preferences in the destination book before receiving emails. The system stores these advance decisions and automatically applies them when acknowledgement requests are received, eliminating the need for real-time user intervention and reducing operational complexity while maintaining selective response capability.
3Ease of operation
If the communication apparatus transfers all reception data to external apparatus for user confirmation, then the user control over acknowledgement response is improved, but the response time is increased due to additional transfer and confirmation steps
Solution Approach 1:
The patent implements partial action by transferring only those reception data to the external apparatus that require user confirmation based on the stored destination preferences. For destinations where automatic response is permitted, the system handles them immediately without transfer. This selective approach reduces the number of items requiring user confirmation and minimizes response time while maintaining user control where needed.

AI summary
Provided is a communication apparatus in which when reception data from a transmission apparatus contains a request for an acknowledgement response, a determination as to whether or not to send an acknowledgement response from the communication apparatus to the transmission apparatus is made, if the acknowledgement response is permitted, an acknowledgement is sent to the transmission apparatus over a network, and when the acknowledgement response is not permitted, reception data containing the acknowledgement response is transferred to the external apparatus.
