Messaging Server Disposition Notification Interworking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current messaging systems, such as SMS, MMS, and RCS, lack the ability to provide comprehensive delivery and read disposition notifications across different networks, especially when messages are interworked from one format to another, leading to uncertainty about the message's reception and display quality.
Innovation Solution
A messaging server system that converts data messages from one format to another (e.g., SMS, MMS, RCS) and processes disposition notification codes to provide detailed delivery and display status notifications to the sending device, including format conversions, image resolution, and screen size information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If message interworking conversion is implemented between different messaging formats (SMS, MMS, RCS), then message compatibility and deliverability across networks are improved, but the ability to provide accurate delivery and read disposition notifications deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism (the messaging system with disposition notification processor) that mediates between the sender and receiver across different network formats. This intermediary captures, translates, and forwards disposition notifications while maintaining their meaning across format conversions, thus preserving notification accuracy despite message interworking
Solution Approach 2:
The patent implements a feedback loop where disposition notifications are sent back from the receiving system to the sending system after message delivery. This feedback mechanism ensures that the sender receives accurate information about message disposition (delivered, read, failed) even when the message has been converted between different formats during transmission
2Productivity
If format conversion is performed during message interworking, then message delivery across different networks is enabled, but information about original message format and display quality is lost
Solution Approach 1:
The patent applies preliminary action by capturing disposition notification information at the point of format conversion, before the message is fully processed by the receiving system. This allows the system to record and preserve information about the original format and conversion details, preventing information loss while enabling cross-network delivery
Data Source
AI summary
The message server system receives a data message transferred by a sending communication system for delivery to a receiving communication system. The data message has a first messaging format with disposition notification codes. The messaging server system converts the data message from the first messaging format to a second messaging format and transfers the data message for delivery to a receiving communication system over a particular communication network. The messaging server system processes the disposition notification codes and responsively transfers a disposition notification for delivery to the sending communication system, indicating that the data message was converted from the first messaging format into the second messaging format, and was transferred over the particular communication network for delivery to the receiving communication system.
