In particular, in the present invention, the OS program may be an open OS program that provides an OPEN API and platform for application program developers, and may include, for example, Apple's iOS, Google's Android, and the like. In addition, the storage unit 150 is one of various applications, operating based on the operating environment of the OS, performing a call service 10 that performs an Internet protocol-based call service, and multimedia playback that plays audio and video. It may include an application (20).

The control unit 160 controls the overall operation of the terminal device 100. Basically, the control unit 160 executes an OS program stored in the storage unit 150 to build an execution environment in which various applications can be driven, and a specific application according to a user's request or a set algorithm through the built execution environment. Or perform a function. In particular, the control unit 160 may execute the call application 10 according to a user's request, and provide an Internet-based call service according to the algorithm of the call application 10.

Particularly, in the present invention, the control unit 160 performs an Internet protocol-based call service in cooperation with the call control device 200 through the call application 10, and an incoming request transmitted from the call control device 200 is received. When received, the operation mode of the call application 10, that is, whether it is operating in the foreground or background operation is checked. In addition, when operating in the foreground, the controller 160 plays an audio file designated for an incoming alarm through the multimedia playback application 20 capable of playing an audio file, outputs an incoming alarm signal, and conversely in the background. When it is in operation, it informs that an incoming request has been received through a local notification function, and outputs an audio file stored for the incoming alarm through the local notification function.

Accordingly, the terminal device 100 according to the present invention can stably output an incoming alarm signal through a local notification function even when the operating system cannot support multitasking.

The procedure for providing an incoming alarm in the Internet protocol based call service according to the present invention will be described in detail with reference to the flowchart of FIG. 4.

In the Internet protocol based call service system according to the present invention, any terminal device 100 may receive an incoming request from another terminal device through a call processing process as shown in FIG. 2 (S205). Here, the incoming request may be received as a SIP-based call control message (eg, SIP INVITE).

As described above, in order to output an incoming alarm signal to a user, the terminal device 100 receiving a call control message requesting an incoming call from another terminal device, first, a call application 10 to process the incoming request goes to the foreground. Check whether it is running (S210).

As a result of the check, if the call application 10 is running in the foreground, the control unit 160 of the terminal device 100 executes the multimedia playback application 200 according to the algorithm of the call application 10 to receive an incoming alarm. By outputting the audio file designated for use, an incoming alarm signal is output (S230). At this time, the call application 10 running in the foreground may interact with a user through the display unit 130 and the input unit 120. Therefore, the control unit 160 is a character string indicating that a call has been made with the caller information (including any one of a caller ID, a caller's name, and a caller's phone number) through the display unit 130 according to the algorithm of the call application 10 In addition, it is possible to output a button to allow the user to accept or reject the incoming call, so that the user can accept or reject the incoming request.

On the other hand, as a result of checking in step S210, when the call application 10 is not running in the foreground, for example, when another application is executed and the call application 10 is switched to the background mode, the control unit ( 160) outputs an incoming alarm signal for the user through a local notification function (S215). That is, when an incoming request is received, it is registered to output audio designated for an incoming alarm, and a local notification function managed by the operating system is activated to output an incoming alarm signal including the designated incoming alarm audio and a character string.

In addition, while the incoming alarm signal is being output through the local notification function as described above, the call application 10 may be activated again by the user who recognizes it and be switched to the foreground.

Therefore, the control unit 160 of the terminal device 100 checks whether or not it is switched to the foreground of the call application 10 while the incoming alarm signal is output through the local notification function (S220). When the call application 10 is switched to the foreground, the output of the incoming alarm signal through the local notification function is stopped (S225). This can be done by removing or stopping the local notification function.

Thereafter, according to the algorithm of the call application 10 switched to the foreground, the control unit 160 of the terminal device 100 executes the multimedia playback application 20 to play the audio file designated for the incoming alarm, so that the incoming alarm signal is generated.

The present invention, when an incoming request transmitted from another terminal device is received, checks whether a call application providing an Internet protocol-based call service in connection with the call control device is operating in the foreground, and is not operating in the foreground. In particular, when operating in the background, by outputting an incoming alarm signal using a local notification function, there is an effect to stably provide an incoming alarm signal regardless of the operating system type of the terminal device.

Particularly, in the present invention, when the call application has priority over other processes, that is, the execution screen of the call application is displayed and is in the foreground state capable of interacting with the user, an incoming alarm is received through the multimedia playback application installed in the terminal device. If the call application is switched to the background while the signal is reproduced and output, and the multimedia playback application is not available, the incoming alarm signal is transmitted using a local notification managed by the operating system of the terminal device. By outputting, it is possible to stably provide an incoming alarm signal regardless of the operating state of the call application.

In addition, according to the present invention, when a call application is activated by a user and is switched back to the foreground while outputting an incoming alarm signal through a local notification function, the output of an incoming alarm signal through a local notification function is stopped to reproduce multimedia. The incoming alarm signal can be continuously output through the application.
