IP Fax Transmission History Segmentation for Mode Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In IPFAX communication, selecting a destination from transmission history is unclear due to varying communication modes (NGN, VoIP GW, intranet) with the same telephone number, leading to potential mistaken transmissions and lack of handling for F codes or passwords.
Innovation Solution
A communication apparatus that stores and retrieves both destination and communication mode during transmission, allowing for accurate retransmission and registration by displaying and managing transmission history, including F codes and passwords, to ensure correct mode selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If only telephone number is stored in transmission history for IPFAX retransmission, then storage simplicity is improved, but transmission accuracy deteriorates due to inability to determine correct communication mode
Solution Approach 1:
The transmission history storage is segmented into multiple fields: telephone number field, communication mode field, F code field, and password field. This segmentation allows each piece of information to be stored and retrieved independently, ensuring that when retransmission is performed, all necessary parameters including the correct communication mode are inherited together, thus maintaining transmission accuracy while keeping the storage structure organized and manageable.
2Adaptability or versatility
If communication mode is not inherited from transmission history, then flexibility in mode selection is improved, but transmission reliability deteriorates due to potential mistaken transmissions
Solution Approach 1:
The system performs preliminary action by automatically inheriting the communication mode from the stored transmission history when retransmission is initiated. This preliminary inheritance of the correct mode eliminates the need for users to manually select from multiple modes (NGN, VoIP GW, intranet), preventing mistaken transmissions while maintaining the flexibility to change modes if users deliberately modify the settings before transmission.
3Loss of information
If F code and password information is not stored in transmission history, then data privacy is improved, but functional completeness deteriorates due to inability to perform secure retransmission
Solution Approach 1:
Security information is segmented into separate storage fields: F code field and password field, distinct from the telephone number and communication mode fields. This segmentation allows the system to store and retrieve security parameters independently. When retransmission is performed, F codes and passwords are automatically inherited together with other transmission parameters, ensuring that secure transmissions can be retransmitted with all necessary authentication information while maintaining organized data management.

AI summary
The present invention provides a communication apparatus configured to transmit image data through a network and a control method therefor. The apparatus stores, as transmission history, a destination and a communication mode for IPFAX at a time of transmission, reads the destination and the communication mode, and transmits image data to the read destination in the read communication mode.
