Terminal Equipment and Call control method for mVoIP and Call service system based Internet Protocol

摘要

The present invention relates to a terminal device for an Internet protocol-based call service capable of stably providing an incoming alarm signal regardless of the operating system type of the terminal device, a method for providing an incoming alarm, and an Internet protocol-based call service system. When a call application processing a protocol-based call service is operating in the foreground, when an incoming request occurs, a multimedia playback application is executed to output an incoming alarm signal, and when an incoming request occurs while the calling application is switched to the background By generating an incoming alarm signal through a local notification function, it is possible to stably provide an incoming alarm regardless of the operating system type of the terminal device.
