VoIP Call Transfer Resource Release via Preliminary Drop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication session transfer methods in VoIP systems consume processor resources and network bandwidth, as they wait for confirmation of a successful transfer before terminating the original connection, leading to inefficiencies.
Innovation Solution
Implementing a method where a media terminal adapter (MTA) can initiate a drop request for a communication session after sending a transfer request, independent of confirmation that the new connection has been established, thereby reducing processing time and freeing up network bandwidth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the first party's device waits for confirmation that the transfer has been completed before terminating participation, then the communication session transfer reliability is improved, but the processor resource consumption increases and the time delay increases
Solution Approach 1:
The first party's device sends a preliminary indication message to the network entity before the transfer is fully completed, allowing the network to prepare for resource release in advance. This preliminary action reduces the waiting time for resource release while maintaining transfer reliability through subsequent confirmation messages.
Solution Approach 2:
The system implements a feedback mechanism where the network entity sends confirmation messages to the first party's device about transfer completion status. This feedback allows the device to make informed decisions about when to terminate participation and release resources, balancing reliability with resource efficiency.
2Reliability

3Productivity
If the first party's device terminates participation immediately after sending the transfer request, then the processor resource efficiency is improved, but the communication session transfer reliability deteriorates
Solution Approach 1:
The first party's device sends a preliminary indication message to the network entity before the transfer is fully completed, allowing the network to prepare for resource release in advance. This preliminary action reduces the waiting time for resource release while maintaining transfer reliability through subsequent confirmation messages.
Solution Approach 2:
The system implements a feedback mechanism where the network entity sends confirmation messages to the first party's device about transfer completion status. This feedback allows the device to make informed decisions about when to terminate participation and release resources, balancing reliability with resource efficiency.
4Stability of the object's composition
If the network bandwidth is consumed by the unneeded connection between the first and second parties, then the connection stability is improved, but the network resource efficiency deteriorates
Solution Approach 1:
The first party's device sends a preliminary indication message to the network entity before the transfer is fully completed, allowing the network to prepare for resource release in advance. This preliminary action reduces the waiting time for resource release while maintaining transfer reliability through subsequent confirmation messages.
Solution Approach 2:
The system implements a feedback mechanism where the network entity sends confirmation messages to the first party's device about transfer completion status. This feedback allows the device to make informed decisions about when to terminate participation and release resources, balancing reliability with resource efficiency.

AI summary
Methods, systems, and apparatus, including computer program products, in which a call transfer can be performed independently of a positive final response in a call transfer to the a third party subject of the call transfer. In some implementations, a first party to the communications session can send a drop/disconnect signal after initiating the call transfer or after receiving an acknowledgement of the initiation of a call transfer.
