Communication State Publishing Gateway for IM Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing instant messaging protocols require terminals to adapt to specific protocols and are limited to Internet communication, making it difficult to publish terminal communication states across different technologies and access networks without establishing an end-to-end call.
Innovation Solution
A method and system that transform a terminal's current communication state into an instant messaging communication state, allowing users to select a voluntary communication state independently of detected states, and transfer this state to an instant messaging server via a publishing gateway connected to both access and packet networks, enabling communication state publishing independently of technology and access networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If terminals adapt to specific instant messaging protocols to determine communication states, then protocol compatibility is improved, but device complexity and adaptability requirements increase
Solution Approach 1:
The patent introduces a communication state publishing gateway as an intermediary component between access networks and instant messaging servers. This gateway transforms communication states from access network-specific formats into standardized instant messaging protocol formats, eliminating the need for terminals to directly adapt to multiple protocols. The gateway handles protocol translation and compatibility, thereby reducing terminal complexity while maintaining versatility.
2Reliability
If terminals establish end-to-end calls to determine communication states, then direct communication reliability is improved, but system complexity and setup requirements increase
Solution Approach 1:
The patent extracts the communication state determination function from direct end-to-end terminal calls and relocates it to a centralized publishing gateway. The gateway independently determines communication states from access networks and publishes them to instant messaging servers without requiring direct terminal-to-terminal calls. This extraction maintains reliability by centralizing state management while reducing the complexity of establishing direct communication paths between terminals.
3Reliability
If communication states are published through access network-specific protocols, then network-specific reliability is improved, but interoperability across different technologies decreases
Solution Approach 1:
The patent implements a universal communication state publishing gateway that serves multiple access network types (circuit-switched and packet-switched networks) and interfaces with various instant messaging servers. The gateway maintains network-specific reliability by accurately representing communication states from different access networks while achieving interoperability by translating all states into a common instant messaging protocol format, enabling seamless communication across diverse technologies.

AI summary
Once a gateway connected to access networks and a packet network has received a notification of a communication state relating a terminal, a gateway that publishes communication states of terminals transforms a current communication state of the terminal into an instant messaging communication state. The instant messaging communication state is then transferred to an instant messaging server so terminals can consult communication states of the terminal.
