MMS Subsystem Segmentation for Oversized Message Delivery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Oversized multimedia messaging service (MMS) messages exceeding size limits in wireless communication systems result in error messages and failed deliveries, frustrating users and wasting time, as existing systems do not effectively manage or split such messages during formulation.
Innovation Solution
A wireless mobile communication device with an MMS subsystem that detects oversized messages and automatically divides them into smaller, size-compliant messages, allowing users to choose whether to split or reformulate, with options for minimizing message count or maintaining sequence, and a multimedia messaging service center server can also perform this function if the device lacks detection capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MMS messages include attachments and graphics to enhance utility, then message functionality is improved, but message size exceeds service provider limits causing delivery failures
Solution Approach 1:
The patent divides oversized MMS messages into multiple smaller message segments that each comply with size limits. The system automatically segments the original message content (text, attachments, graphics) into separate messages, adds segmentation identifiers, and transmits them individually to ensure reliable delivery while preserving the complete message functionality.
2Reliability
If error messages are generated for oversized MMS messages, then delivery failure is detected, but user time is wasted and message formulation must be restarted
Solution Approach 1:
The patent performs preliminary segmentation of oversized messages before transmission attempts. By detecting message size in advance and automatically dividing it into compliant segments, the system prevents delivery failures before they occur, eliminating the need for users to restart message formulation and avoiding wasted time.
3Reliability
If MMS messages are automatically divided into smaller messages, then message delivery reliability is improved, but message complexity and processing requirements increase
Solution Approach 1:
The patent implements self-service automation where the system automatically detects oversized messages, segments them into compliant parts, adds necessary identifiers, and manages transmission without requiring user intervention. This automated self-service approach handles the increased processing complexity internally while maintaining simple user interaction.
4Reliability
If oversized MMS messages are segmented and transmitted, then message delivery is achieved, but network resource usage increases due to multiple transmissions
Solution Approach 1:
The patent segments oversized messages into multiple smaller transmissions that comply with network size limits, enabling successful delivery. While this creates multiple transmissions, it prevents complete message failure and allows for efficient retransmission of only failed segments rather than the entire message, ultimately optimizing network resource utilization.

AI summary
A multimedia messaging service (MMS) subsystem may include a user interface configured to allow a user to formulate an MMS message for delivery to a designated phone number; an oversized MMS message detection subsystem configured to detect when the formulated MMS message exceeds an allowable size limit; and an oversized MMS message management subsystem configured to divide an oversized MMS message into smaller MMS messages that are each within the allowable size limit and to cause each smaller MMS message to be delivered to the designated phone number/address. The MMS subsystem may be part of a wireless mobile communication device. Portions of the MMS subsystem may in addition or instead be part of a multimedia messaging service center (MMSC) server.
