Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communications systems face limitations when trying to facilitate seamless interactions across incompatible Unified Communications and Collaboration (UCC) platforms, requiring a solution to enable cross-domain communication with a single user identifier.
Innovation Solution
A cross-domain system utilizing a bridge server and media gateway to manage notifications and media handling, allowing a single user identifier to be registered across multiple platforms, enabling communication sessions across incompatible platforms by converting protocols and signaling messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single user identifier is registered across multiple incompatible UCC platforms, then cross-platform communication capability is improved, but system complexity increases due to protocol conversion requirements
Solution Approach 1:
The patent introduces a gateway server as an intermediary component that mediates between incompatible UCC platforms. The gateway server receives signaling messages from one platform, converts them to the appropriate protocol format, and forwards them to the target platform. This intermediary approach enables cross-platform communication without requiring changes to the existing UCC platforms, thereby improving adaptability while managing system complexity through a dedicated conversion component.
2Adaptability or versatility
If protocol conversion is implemented to enable cross-platform communication, then compatibility across UCC platforms is improved, but processing time increases due to message transformation operations
Solution Approach 1:
The gateway server performs protocol conversion in advance by maintaining translation rules and mapping relationships between different UCC protocols. When a signaling message arrives, the gateway already has the necessary conversion logic prepared, allowing it to rapidly transform messages without extensive real-time processing. This preliminary preparation of conversion rules reduces the actual processing time during message transformation operations.
3Adaptability or versatility
If existing UCC servers are modified to support cross-domain communication, then integration capability is improved, but system stability deteriorates due to changes in proven systems
Solution Approach 1:
The patent segments the cross-platform communication functionality into a separate gateway server component, distinct from the existing UCC platforms. This segmentation allows the gateway to handle all protocol conversion and cross-domain communication tasks independently, while the original UCC servers continue to operate unchanged. By isolating the integration logic in a dedicated gateway, the system maintains the stability of proven UCC servers while achieving enhanced integration capability through the separate gateway component.

AI summary
A method and system for supporting a cross-domain communication session between communication platforms using a bridge server are provided. In one example, the method includes registering the bridge server with multiple platforms using a user identifier. A request is received from one of the platforms to establish a communication session with a user corresponding to the user identifier. A communication leg is created for each of the platforms. The leg from which the request was received is an incoming leg and the other legs are outgoing legs. The request is sent over the outgoing legs. An acceptance is received from one of the outgoing legs. A cancel message is sent over the outgoing legs from which the acceptance was not received. The acceptance is sent over the incoming leg. The incoming leg and the outgoing leg from which the acceptance was received are bridged to establish the session.
