Centralized TMAS Server Reduces SMS Transmission Time
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing short message service (SMS) and multimedia service (MMS) message transmission in cellular networks involves multiple decentralized Short Message Service Center (SMSC) servers, which increases transmission times due to the use of SS7 protocols and requires communication between multiple servers.
Innovation Solution
The implementation of a centralized Text Messaging Application Server (TMAS) that utilizes Session Initiation Protocol (SIP) signaling to eliminate the need for communication between decentralized SMSC servers, thereby reducing transmission times by centralizing the functionality of multiple SMSC servers and using SIP protocols to transmit messages directly between user devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If decentralized SMSC servers are used for message transmission, then message routing flexibility is improved, but message transmission time increases
Solution Approach 1:
The patent consolidates multiple decentralized SMSC servers into a single centralized SMSC server that handles all message routing operations. This merging eliminates the need for inter-server communication between multiple decentralized SMSC entities, thereby reducing message transmission time while maintaining routing flexibility through the centralized server's ability to determine optimal message paths.
Solution Approach 2:
The centralized SMSC server acts as an intermediary that receives messages from sending user devices and directly routes them to recipient user devices without requiring communication between multiple decentralized SMSC servers. This intermediary approach eliminates the time-consuming inter-server communication protocol exchanges while the centralized server maintains routing intelligence.
2Adaptability or versatility
If multiple decentralized SMSC servers communicate via SS7 protocols, then message routing capability is improved, but system complexity increases
Solution Approach 1:
The patent merges the functionality of multiple decentralized SMSC servers into a single centralized SMSC server, eliminating the complex inter-server communication infrastructure required by SS7 protocols. This consolidation reduces system complexity by removing redundant server entities and their communication pathways while preserving message routing capability within the centralized server.
Solution Approach 2:
The patent extracts the message routing functionality from multiple decentralized SMSC servers and consolidates it into a single centralized entity. This extraction eliminates the need for complex inter-server communication protocols and infrastructure, thereby reducing system complexity while maintaining the essential message routing capability.
3Adaptability or versatility
If decentralized SMSC servers are deployed in cellular networks, then geographic message handling is improved, but transmission speed decreases
Solution Approach 1:
The patent combines multiple geographically distributed SMSC server functionalities into a single centralized SMSC server that maintains the ability to handle messages for different geographic regions. This merging eliminates the need for messages to traverse multiple decentralized server nodes, thereby increasing transmission speed while the centralized server preserves geographic message handling capabilities through its routing intelligence.
