Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solutions for providing translation services in telephone networks are either too costly for companies or require users to manually indicate their language capabilities, slowing down the connection process.

Innovation Solution

A call server system that automatically detects linguistic capabilities of users through SIP signaling messages, eliminating the need for user intervention and utilizing a secondary call server to find and connect available translators for language compatibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a call center with human operators is used to provide translation services, then translation service availability is improved, but operational cost increases significantly

Engineering Contradiction:

Improvetranslation service availabilityVSAvoidoperational cost

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system enables automatic detection of language incompatibility and autonomous initiation of translator connection without human operator intervention. The call server automatically extracts language capabilities from SIP messages, detects incompatibility, and connects translators, making the system self-serving and eliminating the need for expensive human operators in routine translation scenarios.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical system of human operators manually managing translation calls with an automated electronic system. The call server uses software to automatically process SIP signaling messages, detect language incompatibility, and establish translator connections, substituting human manual operations with automated computational processes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If users are asked to manually indicate their language capabilities by pressing keys, then language capability information can be obtained, but connection time increases significantly

Engineering Contradiction:

Improvelanguage capability informationVSAvoidconnection time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The system performs preliminary action by extracting language capability information from SIP signaling messages that are already exchanged during the call setup process. The call server obtains language capabilities automatically from the INVITE and OPTIONS messages before the actual communication begins, eliminating the need for additional user input and reducing connection time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminals automatically provide their language capability information through SIP signaling messages without requiring user intervention. The call server autonomously extracts this information from the signaling messages, making the information provision process self-service and eliminating manual key pressing by users.

Inventive Principle:

Principle #25Self-service

AI summary

The server (CSU) has an extraction unit extracting a session initialization protocol (SIP) signalization message that has an indication of language skills of a user. A receiving unit receives another SIP signalization message comprising an indication of language skills of another user, from a telephone terminal (TB) of the latter user. A sending unit sends a third SIP signalization message comprising the indications of skills, to a call server (CST), and requests an establishment of a communication with a telephone terminal (TT) of a translator corresponding to the indications of skills.
