IMS Exchange Interconnects Multiple Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications infrastructure lacks seamless interoperability across disparate networks and platforms, particularly in the context of IP Multimedia Subsystem (IMS), which hinders the ubiquitous delivery of services and extends the useful life of legacy infrastructure.
Innovation Solution
An intermediary system, IMS Exchange (IMSX), provides interoperability by interconnecting multiple IMS networks through a centrally-located, full-featured Messaging Inter-Carrier Vendor facility, abstracting away complexities and offering a single protocol-agnostic access point for different entities within the IMS ecosystem, enabling seamless service operation and legacy support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple IMS networks are interconnected without an intermediary system, then network complexity and integration difficulty increase, but interoperability and seamless service delivery improve
Solution Approach 1:
The patent introduces an intermediary system (MSC server or GMSC) that acts as a mediator between multiple IMS networks. This intermediary handles message routing, protocol conversion, and network interconnection, thereby improving interoperability while shielding individual networks from the complexity of direct multi-network integration. The intermediary consolidates the integration complexity into a single point rather than requiring complex peer-to-peer connections between all networks.
2Duration of action of stationary object
If legacy infrastructure is supported alongside new IMS networks, then useful life of existing infrastructure is extended, but system complexity and compatibility challenges increase
Solution Approach 1:
The intermediary system serves as a bridge between legacy infrastructure and new IMS networks. It handles protocol translation, message format conversion, and compatibility mediation, allowing legacy systems to remain operational without requiring complex modifications to each legacy component. The intermediary consolidates compatibility management into a single system rather than requiring changes across the entire legacy infrastructure.
Solution Approach 2:
The intermediary system is designed to handle multiple functions simultaneously: it supports both legacy and modern IMS protocols, performs message routing across different network types, and provides service mediation. This multi-functionality allows a single system to manage diverse infrastructure types without requiring separate specialized systems for each legacy platform.
3Adaptability or versatility
If protocol-agnostic access points are implemented, then adaptability to different protocols is improved, but processing complexity and protocol handling overhead increase
Solution Approach 1:
The intermediary system acts as a protocol-agnostic access point that receives, processes, and forwards messages regardless of the specific IMS protocol or network origin. It performs protocol detection, conversion, and routing without requiring each connected network to understand all protocols. The intermediary consolidates protocol handling complexity into itself rather than requiring each network entity to be multi-protocol capable.

AI summary
An intermediary infrastructure that facilitates the interconnection of multiple IP Multimedia Subsystem (IMS) networks. The interconnections may span one or more of the IMS logical planes Services Plane, Control Plane, and Network or Transport Plane. The intermediary offers among other things a process, routing, and switching complex that is able to among other things process incoming messages including using a comprehensive routing repository to complete message routing operations.
