Description

MOBILE COMMUNICATION TERMINAL FOR PLAYING BABY CONTENTS AND METHOD FOR PLAYING BABY CONTENTS USING MOBILE COMMUNICATION TERMINAL}

The present invention relates to a mobile communication terminal for reproducing infant contents in a mobile communication terminal and a method for reproducing the same. Specifically, in a baby mode, a key value of the mobile communication terminal is specified differently from a general communication mode so that the mobile communication terminal is used as an infant. A method and apparatus for reproducing baby contents in a mobile communication terminal which can be used as a dedicated terminal.

Mobile communication terminals such as mobile phones are of great interest to children. Because various functions implemented in the mobile phone, for example, the ringing of the phone, the light emission of the button portion, etc. cause a strong curiosity as much as the infant toy for the infant. For this reason, mobile phones for infants have recently been released. Generally, a mobile phone for infants is a toy mobile phone, and unlike a general mobile phone, there is no number button and only a simple selection button is provided. This infant-only mobile phone makes it easy for infants who lack the ability to recognize and input the keypad to which an animal's character is given instead of a number button for entering a telephone number.

However, infant-only mobile phones do not provide a variety of additional features compared to ordinary mobile phones. By simply pressing a button or opening a folder, it provides the ability to output pre-stored sounds, so toddlers get tired easily and still don't let go of their curiosity about a regular phone. Thus, parents of infants have their children play with their cell phones. In this case, the infant's ability to input to the keypad is significantly lower than that of the general public, causing a problem in which a telephone call is attempted to an unwanted receiver according to the manipulation of the keypad, and various environments set in the mobile phone are changed and released. Even the existing stored information such as phone number is deleted.

Accordingly, an object of the present invention is to provide a method of playing baby contents in a mobile communication terminal that plays back baby contents and limits a part of a communication function while the baby contents are played.

Another object of the present invention is to provide a mobile communication terminal using the method.

According to an aspect of the present invention, there is provided a method of reproducing baby contents in a mobile communication terminal, the method comprising the steps of installing an infant application program on the mobile communication terminal and executing the installed infant application program. And switching to a baby mode in which the infant content is played in a communication mode that is a unique function of the communication terminal. In this case, even when an end key event occurs according to the operation of the mobile terminal by the infant, the baby mode is not switched to the communication mode.

According to another aspect of the present invention, there is provided a mobile communication terminal for playing content for a baby, comprising: a first memory unit for storing an infant application program, and a second memory unit for storing firmware for controlling an end key event; And a controller for interlocking with the first and second memory units, interlocking the firmware and the infant application program, and executing the infant application program to set a baby mode in which the infant content is played in a general communication mode. Here, in the baby mode, the key value of the mobile communication terminal is specified differently from the general communication mode in the baby mode so that the mobile communication terminal can be used as the baby-only terminal, and the termination in the baby mode according to the control authority. The baby mode may not be switched to the normal communication mode even when a key event or a flip down event occurs.

According to the present invention, the infant contents are played in a general mobile communication terminal, and in particular, while the infant contents are played, by limiting the general communication function, that is, attempting a telephone call to a person who does not have a specific relationship with the infant, to an unwanted recipient. It can prevent the phone call from connecting.

Hereinafter, with reference to the accompanying drawings will be described a preferred embodiment of the present invention.

1 is a block diagram of a mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 1, a mobile communication terminal according to an embodiment of the present invention includes a key input unit 110, a display unit 120, a wireless unit 130, an audio unit 140, a first and a second memory unit 150, 160, a camera unit 170, and a controller 180.

The key input unit 110 includes various numeric button keys, a connection key for call connection, an end key for ending a call, a moving key for switching a setting screen to another setting screen, a special key for taking a video and a photo, and the like.

The display unit 120 displays a video and a picture of a specific person selected by the user through the key input unit 110. In particular, as described below, the baby terminal in which the mobile communication terminal plays the infant content in the general communication mode is described. When switching to the baby mode, a variety of infant contents including video and photographs or animal images, animal photographs, infant drawing images, etc. of characters having a specific relationship with the infant, such as parents and relatives of the infant, are displayed.

The wireless unit 130 transmits / receives wireless data with the mobile communication system and performs data communication with a server provided in a corresponding mobile communication company to which the mobile communication terminal subscribes to download a baby application program that executes baby contents in real time. . In the present embodiment, the baby application program will be limited to downloading from the mobile communication company. However, the mobile application program may be basically loaded with the mobile firmware or the mobile operating system program at the time of factory shipment of the terminal.

The audio unit 140 includes a device such as a microphone and a speaker so that the infant and the user of the mobile communication terminal 100 can speak and listen to the sound. You can also record

The first memory unit 150 includes firmware for recognizing and controlling various hardware included in the mobile communication terminal 100, that is, the key input unit 110, the display unit 120, the audio unit 140, and the camera unit 170. (firmware) is saved.

The second memory unit 160 stores downed application programs for children and various videos and photos under the control of the controller 180.

The camera unit 170 is for acquiring a video image of a subject, and the video image obtained from the camera unit 170 may be used as photo data of a specific person. For example, when a user presses a key of the key input unit 110 for capturing an image or a picture, a video image of a specific person is obtained, and when the user presses a key for photographing again, the second memory unit 160 or a separate memory (Not shown).

The controller 180 controls the overall operation of the mobile communication terminal 100, interlocks the firmware stored in the first memory unit 150 with the infant application program stored in the second memory unit 160, and the mobile communication terminal 100. ) Run the baby application program according to the user's operation. When the infant application is executed, the mobile communication terminal 100 is switched to the baby mode in which the infant content is played in the normal communication mode. The mobile communication terminal 100 switched to the baby mode functions as a mobile phone for infants. In this process, the controller 180 transmits a control right for the end key event or the flip-down event that was controlled by the firmware of the first memory unit 150 to the infant application program. Here, the general communication mode refers to a communication mode as a unique function of the mobile communication terminal. That is, in the general communication mode, a telephone call can be made with everyone who has a parent-related relationship, for example, a parent's company colleagues, a friend, or any other person who has no specific relationship with an infant.

However, when the mobile communication terminal 100 is switched to the baby mode, only the designated person, such as a specific person (for example, dad or mother) related to the infant, is set to be able to make a phone call. Therefore, the problem of trying to make a phone call to an unwanted receiver by manipulating a child's key is solved.

In the baby mode, even when the end key event or the flip-down event occurs, the baby mode does not switch to the normal communication mode. In other words, playback of the infant content is not stopped. Specifically, the controller 180 releases the control right for the end key event or the flip down event that the firmware has, and sets the control right to have the infant application. The infant application, which has transferred control rights, continues to maintain the baby mode in which the infant content is played, even if an end key event or a flip-down event occurs according to the infant's key operation while the infant content is being played. That is, in the baby mode, even if an end key event or a flip down event occurs, the baby mode is not switched to the normal communication mode.

In order to switch to the normal communication mode, when a user (eg, a parent of an infant) of the mobile communication terminal 100 inputs a password for releasing the mode, the mobile mode 100 switches to the normal communication mode. In this case, the controller 180 transfers the control right for the end key event or the flip down event from the infant program back to the firmware, so as to control the end key event or the flip down event that the infant application has in the baby mode. Release it.

FIG. 2 is a flowchart of a method of playing content for infants using the mobile communication terminal illustrated in FIG. 1.

Referring to FIG. 2, an infant application is downloaded from a server of a mobile communication company or a server of a contents porvider (CP) through a wired / wireless communication network (S210). In the process of installing the downloaded infant application program on the mobile communication terminal, the firmware for controlling the end key event or the flip-down event is linked with the infant application program. The infant application proposed in this embodiment is implemented by applying the Wireless Internet Platform for Interoperability (WIPI) of the Korea Wireless Internet Standardization Forum (KWISF). WIPI is a nationally developed platform for the standardization of domestic mobile platforms, and acts like a desktop operating system (OS). WIPI began to be a national project in 2001 with the aim of reducing national waste by allowing mobile operators to use the same platform. Since Korean mobile operators have made and used wireless Internet platforms in different ways, content providers have no choice but to make the same content into multiple platforms. Therefore, a number of unnecessary wastes occurred due to content creation and service. WIPI was created to reduce such wastes at the national level. It belongs to the mobile platform special section of the Korea Wireless Internet Standardization Forum (KWISF), SK Telecom, KTF, LG Telecom, Samsung Electronics, LG Electronics, ETRI, TTA, Radio The Institute is registered as a full member, and Wipy is installed on all new terminals according to the interconnection standard of telecommunication equipment.

Subsequently, when the infant application is executed (S220), the mobile communication terminal is switched to the baby mode from the normal communication mode. That is, the infant application receives the control authority for the END key event or the flip down event from the firmware. By default, exit key events and flip-down events are delivered directly to the original equipment manufacturer (OEM), which typically refers to the device area implemented by the terminal manufacturer or to the firmware described above, and terminates a particular application when it is running. do. Therefore, in order to prevent the infant application from terminating, it is controlled through 'OEMC_knlSetSystemOperation ()', which is a system operation function provided by WIPI. When switching to baby mode, call the OEMC_knlSetSystemOperation () function with ("EXITONEND", FALSE) and ("EXITONFLIPDOWN", FALSE) as arguments to set the application to have control over exit key events and flip-down events. In other words, ("EXITONEND", FALSE) and ("EXITONFLIPDOWN", FALSE) are the values that are put into the OEMC_knlSetSystemOperation () function for key control when an exit key or flip down event occurs. For example, if a call is made with OEMC_knlSetSystemOperation ("EXITONEND" :, true) and the exit key event occurs due to an operation of the infant, the infant application terminates. However, when calling OEMC_knlSetSystemOperation ("EXITONEND" :, false), the infant application will continue to run without being terminated. Thus, even when the infant presses the end key or flips in the baby mode, the infant application does not terminate but continues to function as an infant-only mobile phone. In this way, even when an end key event or a flip-down event occurs according to the physical manipulation of the infant, the apparatus is switched to the normal communication mode, thereby preventing the infant from calling an unspecified person.

At the end of the baby mode, ("EXITONEND", TRUE) and ("EXITONFLIPDOWN", TRUE) are called with the arguments to assign control back to the firmware directly for the exit key and flip down event.

Subsequently, in the mobile communication terminal switched to the baby mode, various infant contents are played according to the key manipulation of the infant or the user (parent of the infant) (S240), and when the user ends the infant program (S250), the mobile communication terminal is The baby mode is switched to the normal communication mode (S260).

The infant program according to the present embodiment provides various function settings such as speed dial designation, picture designation, and voice recording in the baby mode. That is, in the baby mode, a phone number, a picture, a voice, and a key mapping function provided in the mobile communication terminal are provided.

When you run Baby Mode, a predefined photo (or video), recording file, and phone number are stored in the form of a file. In this case, the file is stored in a subdirectory of the infant application program, and in the case of a picture, only a path of a picture file stored in the firmware is stored to reduce the storage space of the mobile communication terminal.

In addition, file names of all files include keypad numbers after the file names in index form so that they can be mapped with numeric keys, which improves the efficiency of file management and use. For example, an image file name mapped with key 1 is designated as 'img_1.txt', and a voice recording data file name mapped with key 2 is designated as 'voc_2.voc'. In addition, the file name of the telephone number mapped with the key 3 is designated as Mdn_3.txt.

The photo files stored in the firmware are used in the infant application program as follows.

The image (or video) acquired through the camera installed in the terminal or the image file pushed through the PC or the memory card is stored in a specific directory (terminal resource area) of the firmware. Since the path of this directory varies depending on the manufacturer or the type of terminal, WIPI provides a method that is accessible to most terminals. In this case, OEMC_termResGetCount (), MC_knlCalloc (), and MC_GETDPTR () are used among WIPI-based functions. The OEMC_termResGetCount (“PHOTO”) function is used to get the number of photos stored in the photo directory, the OEMC_termResGetList (“PHOTO”, resName, size) function is used to obtain the file name of the photos, and the OEMC_termResGetSize (“PHOTO”, resName) function. The capacity of the picture is obtained and memory is allocated through MC_knlCalloc (res_size) and MC_GETDPTR (bufid). After that, the photo is copied to the memory allocated by the infant application through the OEMC_termResRead () function. The photo data copied to the memory can be freely displayed in the infant application according to the present embodiment, and the path of the photo obtained above is stored in a file format in a subdirectory of the infant application, and the numbers and keys stored in the baby mode operation are stored. The pad is read from the saved path and displayed on the screen.

When voice recording is used in an infant application according to the present embodiment, MC_mdaClipCreate () and MC_mdaRecord () functions are used among WIPI-based functions.

Currently, mobile phones released through SK Telecom support Enhanced Variable Rate Codec (EVRC) in terminals equipped with WIPI 1.2 or higher platforms. Therefore, when recording a user's voice, a function can be created by calling MC_mdaClipCreate ("IS127") with a parameter, and the voice recording starts when the clip buffer created in MC_mdaRecord () is called. The voice data recorded as described above is stored as a file in a subdirectory of the infant application program according to the embodiment to read and play the stored voice file when the baby mode is executed.

In the case of using the designated shortcut number in the infant application program according to the present embodiment, MV_KEY_REPEAT_EVENT () and MC_phnCallPlace () are used among WIPI-based functions. When the user selects the number of the keypad to be set and inputs and saves the desired phone number, the infant application program stores the received phone number in a buffer and stores the buffer as a file in a subdirectory. do.

When the baby mode is executed, the stored file is read and its numeric value matches the keypad, and when the MV_KEY_REPEAT_EVENT ("long key") event is delivered, the MC_phnCallPlace (MDN) function is called with the stored phone number to try to connect.

When the phone is connected, the baby application waits in the background and the firmware connection screen appears. When the call ends or the end key is pressed, the infant application waiting in the BACKGROUND state is switched to the FOREGROUND state and the baby mode continues.

3 to 7 are diagrams illustrating an execution screen of an infant application program displayed on a display unit of a mobile communication terminal according to an embodiment of the present invention.

Referring to FIG. 3, when a baby application is executed by a user, the mobile communication terminal is switched from a normal communication mode to a baby mode. In the display unit of the mobile communication terminal that has been switched to the baby mode, an intro screen first appears, and after a predetermined time, the display automatically switches to the main screen.

Four icons that can be selected by the user are displayed on the main screen: a baby mode execution icon, a function setting icon, a volume and vibration setting icon, and a help icon. When the user activates the baby mode execution icon by using a special key such as a moving key, and presses a specified key in the activated state or touches the corresponding icon when the terminal supports the touch method, a prompt asking whether to execute the baby mode is performed. You'll see a popup with the text. In the pop-up screen, when the user wants to exit the baby mode, a message indicating a password (for example, '0' four times) is displayed together.

When the user selects execution, the infant content such as various animal photographs set in the baby mode, a specific portrait photograph related to the infant, and a voice are played. At this time, if the user presets a picture, voice, speed dial, etc., each time the corresponding button is pressed, the preset picture, voice, and phone connection are possible. Dial-up in baby mode is limited to certain persons, such as parents or relatives of infants, unlike normal communication mode. Therefore, it is possible to prevent a telephone call from being attempted by an infant by an unwanted receiver.

While the infant content is playing, the user (eg, the parent of the infant) can press the designated password (eg, '0' key 4 consecutive times) to release the baby mode and switch to the normal communication mode.

Referring to FIG. 4, when the function setting icon is selected in the main screen shown in FIG. 3, the function setting screen is switched from the main screen. On the function setting screen, a shortcut number designation icon, a photo designation icon, and a voice recording icon are displayed.

When the user activates the shortcut number designating icon, the function number setting screen is switched to the speed dial designating screen. The user enters the telephone number of the person having a specific relationship with the infant in the designated numeric key on the switched speed dial designation screen, and when the save button is pressed, the corresponding numeric key mapped to the entered telephone number is registered. Subsequently, when the baby presses a long key on the corresponding numeric key button in the baby mode or presses a call key on the corresponding button screen, a telephone call is attempted to the registered number.

Referring to FIG. 5, when the user selects a photo designation icon in the function setting screen illustrated in FIG. 4, the function setting screen is switched to the photo designation screen. The user searches for a picture or video obtained from the camera, and the picture or video searched by the user's key operation is mapped to the designated number key. When the infant presses the corresponding number key, the picture or video is displayed on the screen.

Referring to FIG. 6, when the user selects the voice recording icon on the function setting screen shown in FIG. 4, the voice setting screen is switched from the function setting screen. When the user activates a specific button, the user can record and save the voice. When the baby mode is pressed, the recorded voice is output. That is, the recorded voice is mapped to the designated button key, and when the mapped corresponding button is pressed, the recorded voice is output.

Referring to FIG. 7, when the user selects the volume / vibration setting icon in the function setting screen illustrated in FIG. 4, the function / setting screen switches to the volume / vibration setting screen. The user sets a volume for the recorded voice or sound effect by operating a specific key, and sets or cancels the mobile phone's vibration when the user presses a specified key when the baby mode is executed.

According to the present invention, a baby-only mobile phone, that is, a new concept baby application that can replace a toy mobile phone, is installed in a general mobile communication terminal. Thus, when the infant application is executed, the general mobile communication terminal is switched to the baby mode from the normal communication mode serves as a toy terminal for playing the infant content. In addition, the baby mode does not end even if the infant presses the end key or flips the baby mode. In order to switch back from the baby mode to the normal communication mode, a predetermined key value needs to be input, and thus the infant cannot arbitrarily exit the baby mode. In other words, it is possible to prevent the infant from arbitrarily entering the normal communication mode and attempting to make a phone call to an unwanted recipient or deleting important information. In addition, a general mobile communication terminal installed with an infant application program functions as a function of an infant-only mobile phone, thereby satisfying the desire of an infant having a strong curiosity for the general mobile communication terminal.
