IMPROVING VOICE OVER INTERNET PROTOCOL (VOIP) CALL SETUP SUCCESS RATE AND LATENCY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240187458 titled 'IMPROVING VOICE OVER INTERNET PROTOCOL (VOIP) CALL SETUP SUCCESS RATE AND LATENCY

Simplified Explanation

The patent application describes a method and apparatus for improving voice over internet protocol (VoIP) call setup success rate and latency. The method involves attempting a mobile originated packet switched call across a packet switched network with a TCP connection of the IMS session. In case of a failure, a silent redial of the call is performed via a circuit switched network, followed by a keep alive message transmitted over the packet switched network for reconnection.

• Mobile originated packet switched call setup improvement:

 - Attempting calls across packet switched network with TCP connection
 - Silent redial via circuit switched network in case of failure
 - Keep alive message for reconnection after circuit switched call

• Latency reduction:

 - Efficient call setup process
 - Quick reconnection to packet switched network
 - Minimization of call dropouts

• Improved call success rate:

 - Reducing call failures
 - Enhancing user experience
 - Ensuring reliable VoIP calls

Potential Applications

The technology can be applied in telecommunications, VoIP services, mobile networks, and IMS systems.

Problems Solved

This technology addresses issues related to call setup failures, latency in VoIP calls, and reconnection problems in packet switched networks.

Benefits

The benefits of this technology include improved call success rates, reduced latency, enhanced user experience, and reliable VoIP communication.

Potential Commercial Applications

Potential commercial applications include VoIP service providers, telecommunications companies, mobile network operators, and IMS solution providers.

Possible Prior Art

One possible prior art could be methods for call setup improvement in VoIP systems, but the specific approach of silent redial and keep alive messages may be novel.

How does this technology impact battery life on mobile devices?

The patent application does not provide information on the potential impact of this technology on the battery life of mobile devices. This could be a crucial aspect for users who rely on VoIP calls extensively.

What are the potential security implications of using silent redial and keep alive messages in VoIP calls?

The patent application does not address the security implications of implementing silent redial and keep alive messages in VoIP calls. It would be important to understand how these features may affect the overall security of the communication.

Original Abstract Submitted

a method and apparatus improve voice over internet protocol (voip) call setup success rate and latency. the method provides for attempting a mobile originated packet switched call, by a user equipment (ue), across a packet switched network with a transmission control protocol (tcp) connection of the internet protocol multimedia subsystem (ims) session. a silent redial of the mobile originated packet switched call is performed in response to a failure of the mobile originated packet switched call, via a circuit switched network. a keep alive message is transmitted over the packet switched network after the circuit switched network call, which allows reconnection to the packet switched network.
