Blind Transfer Resource Release via Conditional Dialogue Verification

Solution Overview

Problem

The existing protocols for blind transfer in communication technologies, such as SIP and 3GPP TS24 series, conflict with RFC 3261, leading to issues like unresolved dialogue resources, resource wastage, and increased complexity in implementation.

Innovation Solution

A blind transfer method where a first terminal transmits a request message to a second terminal under the condition that a dialogue between the second terminal and a third terminal is successful, allowing for the release of dialogue resources between the first and second terminals.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing blind transfer protocols (SIP and 3GPP TS24 series) are used, then blind transfer functionality is achieved, but dialogue resources remain unresolved causing resource wastage and implementation complexity

Engineering Contradiction:

Improveresource management reliabilityVSAvoidimplementation complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by establishing a conditional release mechanism where the first terminal sends a release request only after confirming the second terminal has successfully established a dialogue with the third terminal. This preliminary verification ensures resources are released at the correct moment, preventing both resource wastage and implementation complexity by aligning release timing with actual usage requirements.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback through the conditional release mechanism where the first terminal waits for confirmation that the second terminal has successfully established the new dialogue before releasing resources. This feedback loop ensures reliable resource management by base on actual usage status, resolving the contradiction between reliability and complexity.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If dialogue resources are not released after blind transfer, then transfer flexibility is maintained, but communication resource wastage occurs

Engineering Contradiction:

Improvetransfer flexibilityVSAvoidcommunication resource wastage

Core Design Contradiction:

Adaptability or versatilityVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by establishing a conditional release mechanism where the first terminal sends a release request only after confirming the second terminal has successfully established a dialogue with the third terminal. This preliminary verification ensures resources are released at the correct moment, preventing both resource wastage and implementation complexity by aligning release timing with actual usage requirements.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements discarding and recovering by conditionally releasing dialogue resources between the first and second terminals only after the second terminal has successfully established a new dialogue with the third terminal. This ensures resources are discarded (released) when no longer needed, preventing wastage while maintaining transfer flexibility during the transition period.

Inventive Principle:

Principle #34Discarding and recovering

3Speed

If blind transfer is implemented without proper resource release, then transfer speed is maintained, but resource management stability deteriorates

Engineering Contradiction:

Improvetransfer speedVSAvoidresource management stability

Core Design Contradiction:

SpeedVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by establishing a conditional release mechanism where the first terminal sends a release request only after confirming the second terminal has successfully established a dialogue with the third terminal. This preliminary verification ensures resources are released at the correct moment, preventing both resource wastage and implementation complexity by aligning release timing with actual usage requirements.

AI summary

A blind transfer method is executed by a first terminal, and the method includes: under a first condition, transmitting a first request message to a second terminal, the first request message being configured to request for releasing dialogue resources between the first terminal and the second terminal, in which the first condition is that a dialogue between the second terminal and the third terminal is successful; and receiving a first response message transmitted by the second terminal, the first response message being configured to indicate that the second terminal successfully received the first request message.
