Bridge Proxy for Unified Communication Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Unified communication systems face interoperability challenges due to fragmented ecosystems and diverse underlying technologies among vendors, leading to difficulties in seamless company-to-company and company-within communications, despite advancements in real-time communication services.
Innovation Solution
A bridge and control proxy that translates data between unified communication systems and non-compatible devices, using Web services for discovery and advertising, and storing presence information for later use, enabling communication across disparate systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If unified communication systems use diverse vendor protocols and technologies, then functionality and user experience are enhanced, but interoperability between systems deteriorates
Solution Approach 1:
The patent implements a gateway device that acts as an intermediary between unified communication systems using different protocols. The gateway translates SIP protocol messages to H.323 protocol messages and vice versa, enabling interoperability between systems that would otherwise be incompatible. This mediator approach allows diverse vendor functionalities to coexist while maintaining reliable communication through protocol translation.
2Adaptability or versatility
If unified communication systems support multiple protocols, then adaptability across different devices is improved, but system complexity increases
Solution Approach 1:
The patent divides the protocol compatibility function into separate modular components within the gateway device. Each protocol stack (SIP, H.323, XMPP) is implemented as an independent module that can be selectively activated. This segmentation allows the system to support multiple protocols without requiring all protocols to be simultaneously active, reducing overall system complexity while maintaining adaptability.
3Productivity
If unified communication systems integrate real-time communication services, then communication efficiency is improved, but integration challenges with legacy systems worsen
Solution Approach 1:
The gateway device serves as a mediator that bridges modern real-time communication services (VoIP, video conferencing, instant messaging) with legacy telephony systems. The gateway translates real-time protocol messages to traditional telephony signals, enabling integration without requiring legacy systems to be upgraded. This maintains communication efficiency while reducing integration complexity compared to direct integration approaches.

AI summary
This disclosure describes a bridge and control proxy for unified communication systems. The bridge transmits and receives data from a unified communication system. In addition, the bridge transmits and receives data from a non-compatible device. The bridge translates the data between the unified communication system and the non-compatible device. The bridge stores selected data such as presence information for later use by the unified communication system and/or the non-compatible device. Further, the bridge uses Web services to discover, promote, and/or advertise non-compatible devices to the unified communication system.
