Description

  The present invention provides an individual who provides music or sound effects as background sound during a call when a calling terminal and a receiving terminal make a voice call using a background sound source downloaded and stored from a background sound source download service providing device The present invention relates to a method for providing a background sound for a call in a portable terminal.

  In general, a call background sound service is a service that uses music, sound effects, etc. as the background of a voice call when a calling terminal and a receiving terminal coupled to a wired / wireless communication network make a voice call. A conventional call background sound service has been provided by a so-called background sound service providing apparatus coupled to an exchange (MSC) that manages a transmitting terminal or a receiving terminal in a mobile communication network, for example. Recently, with the rapid development of electronic and communication fields, the spread of miniaturized and high performance wired / wireless terminal devices has been greatly expanded. In accordance with such an environment, a method has been proposed in which a telephone background sound can be used even in a wired / wireless terminal apparatus. Of these, “Background music transmission method during call of mobile communication terminal” disclosed in Korean Patent Publication No. 2002-85579 will be described as an example.

  FIG. 1 is a flow chart illustrating a conventional background music transmission method during a call of a mobile communication terminal. Specifically, FIG. 1 is a flowchart showing a process of simultaneously transmitting voice and background music during a call of a mobile communication terminal.

  Referring to FIG. 1, the central processing unit installed in the mobile communication terminal displays a number selection window on the display unit of the mobile communication terminal so that the user can select a telephone number to which background music is added when the call is connected. (Step 101). At this time, the user selects a telephone number to which background music is added when the call is connected in units of individuals or groups (step 103). In addition, the user can specify background music added at the time of call connection by call time zone and number of calls.

  After selecting the telephone number, the central processing unit searches the background music stored in the memory unit and provides a music selection window on the display unit of the user's mobile communication terminal. At this time, the user selects background music set corresponding to the telephone number or the group in the music selection window provided by the central processing unit. The central processing unit stores the information in the memory unit so that the background music corresponding to the telephone number or group specified in step 101 can be output by the speaker simultaneously with the connection of the call path (step 105).

  Thereafter, the user transmits a call connection request signal to the partner terminal through the key input unit of the mobile communication terminal or receives a call connection request signal from the partner terminal (step 107). At this time, the central processing unit determines whether or not a speech path can be formed based on a signal generated by the user's key input unit operation. If the call path is connected as a result of the determination, the central processing unit searches the memory unit for background music corresponding to the incoming call number or the outgoing call number to which the user wants to connect the call (step 109). If the background music exists as a result of the search, it is determined whether there is an input signal for using the background music set corresponding to the incoming / outgoing number (step 111).

  If there is an input signal for using the set background music as a result of the determination in step 111, the signal processing unit first receives the background music from the central processing unit and encodes it (step 113). Thereafter, the voice-encoded background music is transmitted to the other terminal together with the voice signal through the antenna (step 115). As a result of the above process, the background music is output through the speaker at the same time as the call is connected at the other terminal (step 117).

  On the other hand, if there is no background music or there is no input signal for using the set background music as a result of the determination in step 109 or step 111, the central processing unit sends only the audio signal to the partner terminal. Transmission is performed so that the calling terminal and the receiving terminal can talk with each other only by voice (step 119).

  As described above, the conventional background sound providing method in the mobile communication terminal is configured such that the background sound set corresponding to the outgoing call or incoming call number is output on the call path between the outgoing call terminal and the incoming call terminal.

  FIG. 3 is a flowchart illustrating a background sound source download process according to an embodiment of the present invention.

  Referring to FIG. 3, first, the service providing apparatus determines whether a user connection exists for downloading a background sound source (step 300). If it is determined that there is a user connection, the service providing apparatus transmits the background sound source file list stored in the database to the user terminal of the corresponding user (step 302). Thereafter, the service providing apparatus determines whether there is a selection input signal for the specific background sound source file from the user terminal (step 304).

  On the other hand, the transmitted list of background sound source files is displayed through a PC monitor screen or an output device of a personal portable terminal as in the case of a normal computer communication system. In such a case, the user can select a desired background sound source file from the background sound source files in the background sound source file list and listen to the actual sound source in advance (step 306). When the trial request signal is received from the user terminal, the service providing apparatus executes the background sound source selected by the user so that the user can audition the speaker through the user terminal (step 308). At this time, if the user does not like the background sound source, the user can audition the sound of another background sound source file again.

  Thereafter, the user selects any one of the background sound source files and requests the service providing apparatus to download. That is, the service providing apparatus determines whether there is a background sound source download request signal from the user terminal (step 310). If the background sound source download request signal is present as a result of the determination, the service providing apparatus requests the telephone number of the personal portable terminal that transmits the background sound source in response to the background sound source download request by the user. Then, the service providing apparatus receives an input signal for a terminal identifier that can be selected from the telephone number of the personal portable terminal or the personal portable terminal downloaded from the user terminal (step 312).

  In order to transmit the background sound source, the service providing apparatus first calls a terminal that transmits the background sound source (step 314). If the terminal responds (step 316), the service providing apparatus transmits the background sound source selected by the user to the corresponding terminal (step 318). At this time, the service providing apparatus searches for whether the background sound source control program is installed in the personal portable terminal that downloads the background sound source, and then transmits the background sound source control program to the personal portable terminal according to the user's selection. (Step 318). In such a case, the background sound source control program is automatically selected according to the model of the personal portable terminal, transmitted from the service providing apparatus to the personal portable terminal, and installed. Thereafter, the service providing apparatus transmits a transmission completion message for the background sound source transmission to the personal portable terminal (step 320). At this time, the transmission completion message may be displayed on the screen of the personal portable terminal.

  On the other hand, if the user does not request download of the background sound source file in step 310, the service providing apparatus returns to step 304. Of course, the steps 306 and 308 may be omitted, and the step 310 may be performed immediately in the step 304. If the personal portable terminal does not answer the call at step 316, the service providing apparatus can transmit an error message to the user's personal portable terminal (step 322).

  As described above, the user can select and confirm several background sound sources existing in the service providing apparatus 202 one by one, and then can select a favorite background sound source file to receive download to his / her terminal. . The background sound during a call can be used by using the background sound source file and the background sound source control program.

  The background sound source control program mentioned above refers to a program that recognizes a key input during a call in a personal portable terminal and executes a series of commands set corresponding to each dial key. In addition, the background sound source control program outputs the background sound source file downloaded in the personal portable terminal through the screen output unit of the personal portable terminal, so that the selected background sound source file can be auditioned on the terminal. Outputs the selected background sound source file so that it can be deleted. The background sound source control program is set for each numeric key button so that the background sound source file can be used as the background sound during a call. It plays a role that the background sound source set correspondingly is executed, stopped, or changed. The background sound source control program will be described below with specific examples.

  The background sound source control program according to the present invention is mainly composed of two parts. The first part is a part for setting the background sound source stored in the personal portable terminal before the call as the background sound source corresponding to the buttons 1 to 9 of the terminal. The second part is a part for recognizing a user's button input signal during a call, executing a background sound source set to correspond to each button, and adjusting the output volume level of interruption and background sound.

  The background sound source control program according to the present invention is developed by using a development tool provided by a terminal manufacturer or a communication company, and a function for examining a terminal button input signal or a function for reproducing a media file such as a sound source is developed. Provided in the tool. Therefore, if such a function is used, it is possible to check a button input at the terminal.

  In the background sound source control program according to the present invention, each button of the terminal has the following predefined values. Number 0 is KEY NUM0, Number 1 is KEY NUM1, Number 2 is KEY NUM2, Number 3 is KEY NUM3, Number 4 is KEY NUM4, Number 5 is KEY NUM5, Number 6 is KEY NUM6, Number Number 7 corresponds to KEY NUM7, number 8 corresponds to KEY NUM8, number 9 corresponds to KEY NUM9, an asterisk corresponds to KEY STAR, and sharp corresponds to KEY POUND. This value can be set differently for each terminal manufacturer or communication company. Also, the audio file can be played back using the built-in function of the terminal, and the audio file such as the background sound source is played back using a development tool suitable for each terminal without any specific implementation. The function which can be implemented can be implemented.

Among the functions of the background sound source control program according to the present invention, the process of setting the background sound source stored in the personal portable terminal before the call to each button from 1 to 9 of the terminal is stored in the terminal. A first stage of outputting a list of existing background sound sources to the display unit of the terminal, a second stage of selecting one background sound source from the list, and reproducing so that it can be auditioned before setting The third stage is performed in the fourth stage in which the background sound source is set to correspond to any one of the buttons 1 to 9 of the terminal. Such a stage can be implemented, for example, in the following manner.
bgmList = getBgmList (); // Calls the list of background sound sources currently stored in the terminal.
Display.display (bgmList); // Output the background sound source list to the display.
Wait for KeyPressed (keyCode) // button input signal.
{
if (key = background sound source playback) // if it is a button for playing back a background sound source {CurrentAudio = AudioSystem.getAudioClip (); // Make preparations for playing back an audio file.
CurrentAudio.Open (bgmList [indexSelect]); // Prepare for playing the currently selected background sound source.
CurrentAudio.Play (); // Play the prepared background sound source.
}
else if (key = background sound source stop) // If it is a button to stop the currently playing background sound source?
{CurrentAudio.Stop (); // Stop playing the background sound source.
}
else if (key = background sound source deletion) // If it is a button to delete the currently selected background sound source?
{File xFile = File (bgmList [indexSelect]); // Call information on the currently selected background sound source file.
xFile.Delete (); // Delete the background sound source file.
}
else if (key = background sound source setting) // What if the button is set to use the currently selected background sound source during a call?
{Num = keyPressed (); // Wait for the input of any one of buttons 1 to 9.
bgmSetting (num, bgmList [indexSelect]); // Set the selected background sound source as the background sound source corresponding to the input button.
}
else if (key = background sound source list deletion) // If the input button is a button to delete the background sound source list?
{BgmList.Delete (currentIndex); // Delete the currently selected background sound source from the list.
}
}
The background sound source set through the above steps is set to be played in order, set to be played in an arbitrary order, or set to be set as a background sound source corresponding to a specific button by the user Can do.

  In the background sound source control program according to the present invention, the second part of reproducing the background sound source set in the button in response to the input signal of the button during call and adjusting the background sound source volume level is performed at the following steps. The That is, the second part is a first stage for activating the background sound source control program, a second stage for recognizing the button input signal, and a third stage for adjusting the volume level of the background sound source being reproduced and stopped or output. Made in stages. In addition, the input signal of a button input during a call can be easily known by using a development tool provided by a terminal manufacturer or a communication company, as described above.

In the background sound source control program according to the present invention, for example, a part for recognizing a button signal input during a call and playing, stopping, and adjusting the volume level of the background sound source set to correspond to the button Is implemented in the following manner.
bgmList = getBgmList (); // Call the set background sound source information.
// Prepare for playback according to the background sound source information.
CurrentAudio = AudioSystem.getAudioClip (bgmList);
while (true)
{
// Wait for button input.
key = keyPressed ();
// If buttons are 1st to 8th buttons ...
if (key> = KEY NUM1Key <= KEY NUM9) // Background sound playback {
// Cancel any currently playing buttons.
if (CurrentAudio.isPlay () == true) CurrentAudio.Stop ();
// Prepare to play the selected background sound source.
CurrentAudio.Open (bgmList [key]);
// Play the prepared background sound source.
CurrentAudio.Play ();
}
// If button is button 0 ...
else if (key == KEY NUMO) // Background sound source cancellation {
// Cancel any currently playing sound source.
if (CurrentAudio.isPlay () == true) CurrentAudio.Stop ();
}
// If the button is a sharp (#) button, increase the volume.
else if (key = KEY POUND) // Increase the volume {
// Call up the volume of the audio volume currently being played.
currentAudioFormat = AudioSystem.getClipFormats ();
currentVolume = AudioSystem.getVolume ();
// Increase the volume size.
CurrentVolume ++;
// Set the audio volume again by the increased amount.
AudioSystem.setVolume (currentAudioFormat, currentVolume)
}
// If the input button is an asterisk (*), decrease the volume.
Else if (key = KEY STAR) // Reduce the volume {
// Recall the current audio volume size.
currentAudioFormat = AudioSystem.getClipFormats ();
currentVolume = AudioSystem.getVolume ();
// Decrease the volume size.
currentVolume--;
// Set the audio volume again for the reduced size.
AudioSystem.setVolume (currentAudioFormat, currentVolume);
}
}
It is possible to recognize a button signal input during a call through the above steps, play a background sound source set to correspond to the corresponding button, stop the background sound being played, and adjust the volume level. .

  The background sound source control program according to the present invention is an example that is not an actually operated program, and presents only the implementation algorithm thereof, and the terminal manufacturer and model, and the terminal manufacturer or communication company. The actual contents of actual implementation may vary depending on the development tools provided in.

  FIG. 4 is a flowchart illustrating a process of setting a background sound source in a personal portable terminal according to an embodiment of the present invention. Referring to FIG. 4, a central processing unit installed in a personal portable terminal such as an MPU (Micro Process Unit) determines whether there is a key input for executing a predetermined command (step 400). If there is a key input as a result of the determination, the central processing unit first determines whether or not the signal is an incoming call (step 402). That is, in step 400 and step 402, the personal portable terminal waits for a specific button input or incoming call, and if there is a specific button input corresponding to the background sound setting, performs step 412 to specify the background sound setting. If the input is not a button, the terminal 402 determines whether the key input is an incoming call.

  Thereafter, if there is an incoming call, the central processing unit of the personal portable terminal determines whether the call is from the background sound source service providing apparatus. That is, it is determined whether the incoming call is a download of a background sound source file (step 404). If the background sound source file is not downloaded, the central processing unit performs a general incoming call service (step 406).

  If the background sound source file is downloaded as a result of the determination in step 404, the central processing unit downloads the background sound source file and stores it in the personal portable terminal (steps 408 and 410). That is, the terminal corresponding to the personal portable terminal 208 of FIG. 2 receives the background sound source file in response to the incoming download of the background sound source file in response to the call from the service providing apparatus 202, and receives the received background sound source file. Save to memory.

  On the other hand, if the user receives an input to the specific button corresponding to the background sound setting in the standby state of the personal portable terminal in step 400, the central processing unit of the personal portable terminal responds to the input signal of the specific button. Perform steps 414 and below. Specifically, the central processing unit first determines whether the specific button input is a specific button input for setting a background sound source or requesting a background (step 412). The input signal of a specific button for setting or changing the background sound source may be implemented separately by the manufacturer in the button, or by a combination of existing buttons or menu selection. If the input is not a specific button requesting a background sound source change, the corresponding button input is processed as in the general case (step 414).

  On the other hand, if the background sound source is set or changed as a result of the determination in step 412, the central processing unit displays a list of background sound source files stored in the personal portable terminal as an output device of the personal portable terminal. The background sound source file selection from the user is awaited while displaying through (step 416). At this time, the user can select and audition one of the displayed background sound source files (steps 418 and 420). Then, the selected background sound source file is set to a desired specific button (step 422, step 424, step 426).

  As a result of the above process, the user selects several background sound source files stored in the personal portable terminal one by one and listens in advance, then selects the favorite background sound source file and selects his / her own personal sound source file. It can be set as a background sound source during a call on a mobile terminal.
