MMS Gateway Single Domain Routing for Multiple MMSCs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multimedia messaging systems require multiple unique Internet addresses for each Multimedia Messaging Service Center (MMSC), limiting scalability, fault tolerance, and integration of multiple vendors, and making it difficult for service providers to publish a single domain name for all subscribers.
Innovation Solution
A Multimedia Messaging gateway with MM3, MM4, and MM7 interfaces connects to multiple MMSCs, using a database to route messages to the correct MMSC based on subscriber association, allowing messages to be sent using a single domain name, and providing a single point for carrier control processing and message storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple MMSCs are deployed to support more subscribers, then subscriber capacity increases, but the number of unique Internet addresses required increases, making it difficult to publish a single domain name
Solution Approach 1:
The patent introduces a gateway server as an intermediary between external messaging systems and multiple MMSCs. This gateway server presents a single Internet address to external systems while internally routing messages to multiple MMSCs based on subscriber information. The gateway server acts as a mediator that abstracts the complexity of multiple MMSC addresses from external senders, allowing them to use a single domain name regardless of how many MMSCs are deployed in the network.
2Ease of operation
If a single MMSC is used to serve all subscribers, then the system is simpler to operate, but scalability and fault tolerance are limited
Solution Approach 1:
The patent divides the MMSC functionality into multiple separate MMSC instances that can be independently operated and managed. Each MMSC can be operated by different vendors or serve different geographic regions, allowing for modular deployment. The gateway server coordinates these segmented MMSCs, enabling the system to maintain operational simplicity from an external perspective while achieving scalability and fault tolerance through the distributed architecture.
Solution Approach 2:
The patent combines multiple MMSCs into a unified system managed by a single gateway server. While the MMSCs remain physically separate for scalability and vendor diversity, the gateway server merges their management interface into a single point of control. This allows operators to manage multiple MMSCs as if they were a single system, maintaining ease of operation while benefiting from the scalability and fault tolerance of having multiple distributed components.
3Reliability
If multiple MMSCs from different vendors are integrated, then system reliability and vendor independence improve, but the complexity of managing multiple interfaces and protocols increases
Solution Approach 1:
The gateway server is designed with universal functionality to interface with multiple different MMSC vendors through various standardized protocols (MM0, MM1, MM3, MM4, MM7, and WAP). It implements multiple protocol stacks and adaptation layers that allow it to communicate with diverse MMSC implementations uniformly. This multi-functional capability enables the system to integrate vendors independently while presenting a consistent interface, reducing the complexity that would otherwise arise from managing multiple vendor-specific interfaces.
Data Source
AI summary
Wireless carrier networks can utilize multiple MMSCs all accessed by a message sender with a message addressed to a single Internet domain, providing a single point of entry for messages into the network of MMSCs and maintaining routing information sufficient to route messages to all subscribers via the MMSC.
