MMSC Interoperability via Exchange Relay and Format Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-media messaging centers (MMSCs) face challenges in interoperation due to format compatibility issues and the need for individual agreements with other MMSCs, leading to slow progress in enabling communication between users of different MMSCs.
Innovation Solution
An exchange relay system that enables communication between MMSCs by using message adaptation technology, supporting various formats, and providing a centralized platform for routing multimedia messages across different networks, including CDMA and GSM, while managing bandwidth and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If MMSCs convert data to recipient's preferred format to enable communication, then compatibility between different MMSCs is improved, but device complexity and processing overhead increase
Solution Approach 1:
The patent introduces a format conversion server as an intermediary component that handles format conversion between different MMSCs. This mediator receives messages from source MMSCs, converts them to the appropriate formats for destination MMSCs, and forwards them. This approach resolves the contradiction by centralizing the complexity in a dedicated conversion server rather than requiring every MMSC to support multiple formats and perform conversions, thus improving compatibility while managing complexity through specialization.
2Adaptability or versatility
If each MMSC negotiates separate agreements with other MMSCs to establish reciprocal relationships, then interoperability between specific MMSC pairs is enabled, but the complexity of setup and maintenance increases significantly
Solution Approach 1:
The patent implements a universal format conversion server that serves multiple MMSCs simultaneously, enabling a single infrastructure to handle format conversion for numerous MMSC pairs. This universal system allows any MMSC to communicate with any other MMSC through the conversion server, eliminating the need for each MMSC to negotiate separate bilateral agreements. The conversion server maintains a registry of supported formats for different MMSCs and automatically performs appropriate conversions, thus achieving widespread interoperability through a single multi-functional platform rather than multiple pairwise arrangements.
3Adaptability or versatility
If MMSCs support multiple data formats to accommodate different handsets, then adaptability to various devices is improved, but the complexity of format management and restrictions increases
Solution Approach 1:
The patent extracts the format management complexity from individual MMSCs and concentrates it in a dedicated format conversion server. Instead of each MMSC maintaining knowledge of multiple formats and their restrictions, the conversion server is specifically designed to handle format conversion and maintains a centralized registry of format capabilities for different MMSCs and handsets. This extraction principle resolves the contradiction by removing format management complexity from the general MMSC architecture and placing it in a specialized component that handles only format conversion tasks.
4Adaptability or versatility
If MMSCs attempt to pass messages to other MMSCs with different formats and restrictions, then communication between different networks is enabled, but message rejection risk increases
Solution Approach 1:
The patent applies preliminary action by performing format conversion before message transmission to the destination MMSC. The format conversion server receives the message from the source MMSC, proactively converts it to the appropriate format based on the destination MMSC's capabilities, and then forwards the converted message. This preliminary conversion ensures that the message is already in the correct format when received by the destination MMSC, eliminating the risk of rejection due to format incompatibility and ensuring reliable cross-network communication.

AI summary
A method and apparatus for providing an exchange server to couple multiple MMSCs, the exchange server including a queue to receive the MMS message if the recipient MMSC does not have bandwidth available.
