Abrégé

The present disclosure provides an optimal method of delivering a called party's set video during a voice call connection to the calling party as video Customized Alerting Tones (CAT). More specifically, to generate a video call that delivers the video CAT in the form of early media from a voice call, the disclosure utilizes the early session model suggested by the 3GPP standard to provide a communication protocol for negotiating and establishing a session for the early media. Additionally, the present disclosure provides a method of performing exception handling in a communication protocol for video CAT delivery to ensure calling stability in abnormalities such as errors occurring in the codec negotiation process for video CAT in the network, server failure situations, and user equipment and server malfunctions.

Abrégé

Analyzing the condition of a road surface by using a frequency-of-interest or a resonance sound in a tire. A training audio signal is sent to a learning unit, a label generator and a frequency selection model that does not complete learning. The training audio signal is obtained by collecting driving noise generated when a vehicle travels on a road. The label generator generates a label audio-of-interest signal by attenuating a band other than a frequency-of-interest band in the training audio signal. The frequency selection model derives a training imitated audio-of-interest signal imitating an audio-of-interest signal by performing a plurality of operations in which an unlearned weight is applied to the training audio signal. The learning unit calculates a generation loss that is a difference between the training imitated audio-of-interest signal and the label audio-of-interest signal, and performs optimization of updating the weight of the frequency selection model.
