The present invention relates to a method for transmitting an missed message of a mobile terminal. In particular, when the counterpart mobile terminal is incapable of receiving a message, the missed message of the mobile terminal can select and transmit any one of a voice message, a text message, and a video message. It relates to a delivery method.

General wired and wireless telephones are equipped with an automatic answering function on the phone itself, and when the user has set the automatic answering function, the call is sent out and a voice message can be recorded on the phone according to the other party's choice.

On the contrary, when the mobile terminal does not receive a call, the mobile switching center (MSC) broadcasts a guide message on whether to leave a voice message. In other words, when you try to make a phone call with the other party's mobile device, or the other party's mobile device is turned off or the other party is not receiving a call, 'Your phone is off and you are connecting to the voicemail.' Or, the message 'You are connecting to the voicemail because you can not answer the phone' appears. At this time, you can wait for the connection to the voicemail and record the voice message that you want to leave on the mobile terminal.

1 is a flowchart illustrating a missed message transmission method according to the prior art, in which step S100 of attempting a telephone call from a mobile terminal A to a mobile terminal B, and the power of the mobile terminal B is turned off or powered; Is turned on but the user of the mobile terminal B does not receive a call, such as step S101 in which the mobile terminal B is in an unreceiving state, and the voice guidance on whether to leave a contact number or a voice message at the exchange (S102). And (S103), in which the user of the mobile terminal A leaves a voice message, and notifying the mobile terminal B of the fact that the user of the mobile terminal A has left a voice message in the form of a short message service (SMS). (S104), and the mobile terminal B connects to the voicemail server and checks the voice message (S105).

In other words, when a user of the mobile terminal A leaves a voice message, the user stores the voice message in a voice mail server and transmits a short message to the mobile terminal B from the Short Message Service Center (SMSC) indicating the arrival of the voice message. .

At this time, the confirmation of the voice message is possible by the mobile terminal B connecting to a predetermined number for accessing the voice mail server and listening to the stored voice type message.

However, in the prior art as described above, when the other party does not receive the call, there is a problem in that the user can narrow the user selection because there is no choice but to leave the missed message in the form of a contact number or voice message.

Therefore, the present invention was devised in view of the above problems, and when the other party's mobile terminal is turned off or the phone does not receive a call despite the ringing tone, the contact number or voice message is not received. In addition, an object of the present invention is to provide a missed message delivery method of a mobile terminal, which enables to leave an absent message in the form of a video message and a text message.

According to an aspect of the present invention, there is provided a method of transmitting a missed message for a portable terminal, the method comprising: attempting a telephone call from a first portable terminal to a second portable terminal; Voice guidance for number, voice message or text message transmission, and when the text message transmission is selected, a predetermined frequency for executing the short message service module of the first mobile terminal is generated by the exchange (MSC) and the second message is transmitted. Transmitting the number of the portable terminal to the first portable terminal, executing the short message service module of the first portable terminal corresponding to the predetermined frequency tone and storing the received number of the second portable terminal as a transmission number; And generating a short message in the first mobile terminal and transmitting the short message to the transmission number. And that is characterized.

In addition, the present invention for achieving the above object, in the method for transmitting the missed message of the portable terminal, when the first mobile terminal attempts a telephone call from the second portable terminal to the second portable terminal of the second portable terminal; Storing a number, providing voice guidance for transmission of a contact number, voice message or video message when the second mobile terminal is unreceivable; and if the video message transmission is selected, the first mobile terminal in the MSC. Generating a predetermined frequency tone for executing the videomail module of the mobile terminal; executing a videomail module of the first mobile terminal corresponding to the predetermined frequency tone, inputting and storing a video message; After inputting the video message of the terminal, the number and video message data of the second mobile terminal to the video mail server. Transmitting a short message in the form of a WAP (Wireless Application Protocol) push indicating the arrival of a video message from the video mail server to the second mobile terminal, and transmitting the video mail from the second mobile terminal. Connecting to a server and checking the video message.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart illustrating a method of delivering a video message to a missed message according to the present invention, and as shown therein, attempting a telephone call from the mobile terminal A (outgoing mobile terminal) to the mobile terminal B (receiving mobile terminal). (S201), the step of temporarily storing the number of the portable terminal B in the portable terminal A (S202), the step (S203) in which the portable terminal B is in an unreceivable state, any one of a contact number, a voice message or a video message. Performing a voice guidance on whether to leave (S204), selecting the video message transmission in the mobile terminal B (S205), and generating a predetermined frequency tone corresponding to the selection in the switching unit MSC. In step S206, and when the predetermined frequency tone is a frequency for executing the video mail module of the mobile terminal A, the video mail module of the mobile terminal A is activated. Step (S207, S208), and inputting a video message in the mobile terminal A to transmit the video message and the number of the mobile terminal B to the videomail server (S209, S210), and carry it to the videomail server. Storing the number of the terminal B and video message data (S211), transmitting a short message for notifying arrival of a video message from the videomail server to the portable terminal B (S212), and the videomail server from the portable terminal B; In step S213, the video message is accessed.

When the mobile terminal A makes a call to the mobile terminal B (S201), the mobile terminal A stores the telephone number in advance (S202) in case of using the number of the mobile terminal B when the call fails. If the mobile terminal B is turned off, in an unreceivable area, or in an incapable reception state (S203), such as not being arbitrarily received by the user, the exchange notifies the user of the mobile terminal A that a call is not possible through a guide message. It asks whether to leave one of the contact number, voice message or video message (S204).

In this case, the contact number, voice message, or video message is selected by the corresponding number, respectively, so that the user can select the button of the corresponding number according to the announcement (S205).

The user of the mobile terminal A decides to leave a video message and selects a predetermined number (e.g., 1 for a contact number, 2 for a voice message, 3 for a video message, 3). Then, the exchange generates a unique tone for the predetermined number (S206). Usually, the unique tone generated by the exchange is a predetermined frequency tone that is indistinguishable from a person. For example, when a beeping sound is generated, the portable terminal A detects the frequency of the tone (S207), and the corresponding tone is generated. The video message module is executed (S208).

At this time, the mobile terminal A transmits the video message data including the video data and the audio data to the video mail server. The mobile terminal A adopts the streaming method and transmits the video message data to the memory of the mobile terminal in real time. There is a method of temporarily setting and uploading at the same time after finishing video recording. In this case, the number of the portable terminal B stored in the portable terminal A is transmitted to the videomail server (S209, S210).

The video mail server stores the received video message data and notifies the mobile terminal B of a video message arrival using a short message service, which is a WAP push type SMS service rather than a simple text message transmission.

In other words, by defining one teleservice ID (TID: TeleService ID) of the SMS message and specifying a callback (Uniform Resource Locator) in the user data, the site specified in the callback URL if the user who received the SMS message desires it. You can access it directly to get the information you want.

3 is a flowchart illustrating a method of transferring a text message to an missed message according to the present invention, as shown in the step S301 of attempting a phone call from the mobile terminal A to the mobile terminal B, and the mobile terminal B receiving the message. In step S302, which is in a disabled state, and accordingly performing a voice guidance on whether to transmit a contact number, voice message or text message (S303), and selecting the text message transmission in the mobile terminal A (S304) and Generating a predetermined frequency tone corresponding to the selection at the exchange, and transmitting the number of the mobile terminal B to the mobile terminal A (S305), wherein the predetermined frequency tone is the short message service module in the mobile terminal A; If it is determined that the frequency tone to be executed to execute the SMS module of the mobile terminal A and at the same time stores the number of the received mobile terminal B as a transmission number System as (S306, S307), and the portable terminal A of the SMS module is running takes place in the step (S308) of writing and transmitting a text message content, step (S309) of receiving the text message in a wireless terminal B.

In step S305, the exchange transmits the number of the mobile terminal B to the mobile terminal A. The DTMF tone corresponding to the number of the mobile terminal B is transmitted to the mobile terminal A using the dual frequency multi-frequency (DTMF). The mobile terminal A receiving the DTMF tones detects the number of the mobile terminal B sequentially through an analog / digital converter, a bandpass filter, and a number detection matrix.

FIG. 4 is a block diagram showing an apparatus for converting DTMF tones transmitted from an exchange according to the present invention into numbers. When an analog DTMF tone is input as shown in FIG. The signal is converted into a signal and passed through a digital bandpass filter (111 to 118) passing frequencies of 1633 Hz, 1447 Hz, 1366 Hz, 1209 Hz, 697 Hz, 770 Hz, 852 Hz, and 941 Hz, respectively.

At this time, if the signal passes the predetermined digital bandpass filters 110 to 117, the logic value 1 (High) is transmitted, and if the signal does not pass, the logic value 0 (Low) is transmitted to the number detection matrix 120. The number detection matrix 120 detects a corresponding telephone number.

As shown in FIG. 4 (b), two DTMF frequencies, one at each of four frequencies of the low frequency group 697, 770, 852, and 941 Hz and the high frequency group 1209, 1336, 1477, and 1633 Hz, are simultaneously displayed. Compose one digit with frequency.

For example, when an analog DTMF tone having frequencies of 1477 Hz and 852 Hz is input to the analog-to-digital converter 100, the logical value 1 passes through the digital bandpass filter 111 of 1447 Hz and the digital bandpass filter 116 of 852 Hz. The remaining digital band pass filters 110, 112 ˜ 115, and 117 are cut off to output a logic value 0. Accordingly, the number detection matrix 120 receiving the input detects the number 9 having a frequency of 852 Hz in the low frequency group and 1447 Hz in the high frequency group.

FIG. 5 is a block diagram showing an apparatus for executing a videomail module or a short message service module of a portable terminal according to a predetermined frequency tone generated by an exchange according to the present invention. When the exchange generates a predetermined frequency tone, the analog-to-digital converter 200 ) Is converted into a digital signal and input to the digital bandpass filter 210. When the output of the digital bandpass filter 210 is greater than or equal to a predetermined value, the filter output converter 220 converts the output to 1, and conversely, the filter output converter 220 converts the output to 0 when the output is less than a predetermined value.

Therefore, when the conversion value is 1, the videomail module or the short message service module of the mobile terminal is executed, and when the conversion value is 0, it is not executed.

 As described in detail above, the present invention can go one step further from the existing service form that leaves the voice message when the other party's portable terminal cannot receive, and can select various types of missed messages such as a video message or a short message according to the user's taste. It has an effect.
