Multimedia Message Transfer Recipient Status Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia messaging service (MMS) interfaces, particularly MM4, lack the ability to provide detailed recipient-specific status information in acknowledgement messages, making it difficult to identify and address partial addressing failures when sending messages to multiple recipients across different MMS environments.
Innovation Solution
Incorporating an additional information element in the MM4_forward.RES protocol data unit message to include a list of recipients and their corresponding status, allowing for detailed acknowledgement of message transmission status to each recipient, enabling retransmission of messages to specific recipients with incomplete or failed transmissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the MM4 interface sends messages to multiple recipients using a single message ID, then message transfer efficiency is improved, but the ability to identify and report individual recipient delivery status deteriorates
Solution Approach 1:
The patent segments the delivery status information by introducing a list of information elements in the MM4_forward.RES message, where each element contains a recipient identifier and corresponding delivery status. This segmentation allows individual recipient status tracking while maintaining the efficient single-message transfer mechanism, resolving the contradiction between transfer efficiency and information completeness
Solution Approach 2:
The patent implements a feedback mechanism by requiring the recipient MMS relay/server to return detailed delivery status information for each recipient in the MM4_forward.RES message. This feedback loop provides the originator MMS relay/server with comprehensive delivery information, enabling it to identify partial addressing failures and take appropriate actions while maintaining efficient message transfer
2Device complexity
If the response message contains only message ID without recipient-specific information, then message protocol simplicity is maintained, but the ability to detect and address partial addressing failures deteriorates
Solution Approach 1:
The patent segments the response message structure by adding a list of information elements, where each element is a structured pair of recipient identifier and delivery status. This segmentation provides detailed failure detection capability while maintaining a systematic and organized protocol structure, preventing excessive complexity
Solution Approach 2:
The patent introduces an intermediary structure (the list of information elements) that mediates between the simple message transfer mechanism and the detailed status reporting requirement. This intermediary layer organizes the status information in a structured format that enhances detection capability without significantly complicating the overall protocol
3Reliability
If individual retransmission to each recipient is implemented, then complete delivery reliability is improved, but message transfer efficiency and network resource utilization deteriorate
Solution Approach 1:
The patent applies partial action by enabling selective retransmission based on the detailed status information received. Instead of retransmitting to all recipients, the system retransmits only to those who failed to receive the message, as identified by the delivery status list. This ensures complete delivery reliability while avoiding unnecessary retransmissions that would reduce efficiency
Solution Approach 2:
The feedback mechanism provides the originator MMS relay/server with precise information about which recipients failed to receive the message. This feedback enables intelligent decision-making for retransmission, ensuring reliability by targeting only the necessary recipients rather than performing exhaustive retransmissions to all recipients
Data Source
AI summary
A method for multi-media message transfer transmits a message to multiple recipients. The method includes receiving a message addressed to multiple recipients. The method also includes determining an indication of a state of each recipient. The method also includes transmitting an acknowledgement. The acknowledgment includes at least one message identifying at least one recipient and the associated state of the at least one recipient.
