Abstract

PURPOSE: A method for converting a bell sound of a telephone is provided to convert a uniform and simple bell sound of the telephone into a sound source or a moving picture including an advertisement, a music, and a message. CONSTITUTION: If a user terminal is a terminal capable of service, a sound source providing server asks a user whether a user's own voice is recorded. If the user transmits a message that the user's own voice is recorded, the sound source providing server inactivates a DTMF(Dual Tone Multi Frequency) sensing mode of a DTMF detector. The user records the user's own voice in the state in which the DTMF sensing mode of the DTMF detector is inactivated. After the user records the user's own voice, the sound source providing server activates the DTMF sensing mode of the DTMF detector. The user terminal transmits the recorded voice of the user to a sound source database unit of the sound source providing server. If the sound source database unit receives the voice of the user, the sound source providing server transmits a DTMF command code to a bell sound converter. If the DTMF detector detects a specific DTMF for instructing the start of storage, a sound source inputted to an encoder is stored in a sound source storing unit. If the DTMF detector detects a specific DTMF for instructing the end of storage or a designation time is completed, the sound source inputted to the encoder is not stored in the sound source storing unit.

Hereinafter, the principle of converting the ring tone of the phone by using the conversion method according to the present invention will be described in detail.

When a user makes a call to the user terminal 10 and a call path is formed between the user terminal 10 and the sound source providing server 30 through the communication network base station 40, the control program 203 activates DTMF. The program is activated to activate the user terminal 10 in the DTMF detection mode. In general, the QCELP and EVRC coded sound sources coming into the ringtone converter 20 are converted into PCM form through the encoder 201 and then sent to the speaker unit 10d, but the DTMF active program When 204 is activated, the signal in the form of a packet coded with the QCELP and EVRC is converted into a PCM form through an encoder and is sent to the speaker unit 10d via the DTMF detector 202.

When the user makes a call to the sound source providing server 30 using the keypad of the dialing unit 10a on the user terminal 10, the control program 203 checks the telephone number to be dialed to activate the DTMF. It is determined whether to execute the program 204. At this time, if the telephone number input by the user is the telephone number of the sound source providing server 30, the DTMF activation program 204 is executed and the DTMF detector 202 receiving the command of the DTMF activation program 204 receives a DTMF signal. Detect. As a result, the user terminal 10 and the sound source providing server 30 can communicate with each other through the DTMF command code.

The sound source providing server 30 registers as a member in the sound source providing server 30 and inputs information about itself in the member information database unit 30b to convert the ring tone of the user terminal 10. In order to connect to the sound source providing server 30 in order to search for information on the user and confirm that the user is a legitimate user, the sound source desired by the user is extracted from the sound source database unit 30a and transmitted to the encoder 201. do.

That is, the sound source providing server 30 sends a guide message and a sample sound source to the user to select a sound source (any one of an advertisement, music, message, etc.) that the user wants to store in his terminal, and in response, the user Transmits a DTMF command code for selecting a sound source that the user wants to store through the keypad of the dialing unit 10a. In response, the sound source providing server 30 sends the selected sound source to the exchange 40a of the communication network base station 40 in the PCM form together with a DTMF command code for notifying the start of recording of the sound source selected by the user. ) Converts a PCM-type sound source into a packet of QCELP or EVRC and sends it to the ringtone converter 20.

The ringtone converter 20 converts the packet form of QCELO or EVRC introduced into the encoder 201 into a PCM form and transmits the packet to the DTMF detector.

The DTMF detector 20a detects the DTMF indicating the start of recording, and thus connects the switch 206 connecting the encoder 201 and the sound source storage unit 205 to the QCELP coming from the switch 40a. Alternatively, the EVRC packet is stored in the sound source storage unit 205. At the same time, the PCM type sound source that has passed through the DTMF detector 202 is transmitted to the speaker unit 10d so that the user can hear the sound source.

When the sound source providing server 30 transmits a DTMF command code for terminating recording of the selected sound source, the DTMF detector 202 again disconnects the switch 206 between the encoder 201 and the sound source storage unit 205. To end the storage of the selected sound source.

The encoder 201 may directly transmit the sound source received from the sound source providing server 30 to the speaker unit 10d and / or the DTMF detector 202 in the user terminal 10, but the exchanger ( When a signal is received from 30a), a sound source, which is already stored in the sound source storage unit 205, may be transmitted to the speaker unit 10d to replace the ring tone.

The DTMF command code may be implemented in various ways. For example, "1,2,3,4,5,6,7,8,9,0, #, *, A, B, C, D", or the like may be adopted as the DTMF command code. May be adopted. In particular, DTMF, such as "A, B, C, D" is a DTMF that can not be input in a normal telephone, so it is preferable to use such DTMF when delivering a very important command. For example, it may be used as a storage command code used when storing a predetermined sound source from the sound source providing server 30 to the user terminal 10.

The data structure to which the selected sound source is transmitted may be in the form of "DTMF meaning storage start + selected sound source + DTMF meaning storage ending". Therefore, when the user terminal 10 detects "DTMF meaning storage start", the "selected sound source" is stored in the sound source storage unit 205, and the user terminal 10 indicates "save storage." DTMF "is detected and the save is completed. That is, when the DTMF detector 202 detects a specific DTMF commanding the start of storage among the signals coming into the ringtone converter 20, the DTMF detector 202 transmits a predetermined command to the control program 203. Accordingly, the control program 203 connects the switch 206 located between the encoder 201 and the sound source storage unit 205 to receive the sound source coming into the encoder 201 from the sound source storage unit 205. ).

On the other hand, the DTMF detector 202 detects a specific DTMF commanding the 'end of storage' of the signal coming into the ringtone converter 20 or operates a timer at the start of storage, when the predetermined time is completed, the DTMF detector 202 ) Transmits a predetermined command to the control program 203 so that the control program 203 blocks the switch 206 so that the sound source coming into the encoder 201 is stored in the sound source storage unit 205. Stop it.

If the user wants to record his / her voice and use it as the ring tone for the user terminal 10, his voice through the terminal by sending a specific DTMF along with a message to record the sound source transmitted through the terminal. You can program to deactivate the DTMF detection mode during recording and to activate the DTMF detection mode after recording is complete.

The method for storing the sound source including the above-described advertisement, music, message, etc. in the user terminal 10, the Internet in place of the sound source providing server 30 when the user terminal 10 is used in the Internet mode The desired sound source and the like may be selected from the sound source database unit 30a of the server and stored in the user terminal 10. In this case, instead of storing the selected sound source using the DTMF command code or frequency combination, a method of downloading the selected sound source through an internet browser may be used.

FIG. 2 is a diagram illustrating a step by step method of storing a sound source or the like to be used as an incoming call ring instead of a telephone ringing tone in a user terminal.

Hereinafter, each step will be described in detail.

When the user dials using the dialing unit 10a of the user terminal 10, the control program 203 checks whether the telephone number dialed by the user is the telephone number of the sound source providing server 30. . If the phone number is a general phone number other than the phone number of the sound source providing server 30, the user is sent to a destination, and if the phone number is the phone number of the sound source providing server 30, the control. The program 203 executes the DTMF activation program 204.

When the call is connected to the sound source providing server 30, the sound source providing server 30 pops up a message asking whether or not to record to the terminal that is currently making the call. The sound source providing server 30 terminates the call after sending the SMS to the sound source providing server 30 when the user sends a positive message to the sound source providing server 30 and the sound source providing server 30 is connected to the user terminal (30). 10) prompts you to enter the number.

When the user enters the number of his user terminal 10, the sound source providing server 30 by contrasting this number and information about the user already recorded in the member information database unit 30b the user terminal It is determined whether the terminal 10 is a serviceable terminal. If it is determined that the terminal is not available for service, the sound source providing server 30 terminates the call. ) Prompts the user again to record the voice.

If the user sends a message that the user will record their voice, the sound source providing server 30 deactivates the DTMF detection mode of the DTMF detector 202, so that the user can record his or her voice during this time. After this is completed, the sound source providing server 30 activates the DTMF detection mode of the DTMF detector 202 again and transfers the recorded voice sound source to the sound source database unit 30a of the sound source providing server 30. Bring.

If the user sends a message not to record his or her voice, the sound source providing server 30 presents the user with various types of sound sources stored in the sound source database unit 30a so that the user can select one of them. Bring up a message asking you to select.

When the user records his or her sound source or selects a random sound source, the sound source providing server 30 activates the DTMF detection mode of the DTMF detector 202, and then " DTMF command code indicating the start of storage + storage. A DTMF command code consisting of a "sound source + DTMF command code indicating the end of storage" is transmitted to the ringtone converter 20.

At this time, when the DTMF detector 202 detects a specific DTMF commanding the start of storage among the signals coming into the ringtone converter 20, the DTMF detector 202 transmits a predetermined command to the control program 203. Accordingly, the control program 203 connects the switch 206 located between the encoder 201 and the sound source storage unit 205 to receive the sound source coming into the encoder 201 from the sound source storage unit 205. ). On the other hand, the DTMF detector 202 detects a specific DTMF commanding the 'end of storage' of the signal coming into the ringtone converter 20 or operates a timer at the start of storage, when the predetermined time is completed, the DTMF detector 202 ) Transmits a predetermined command to the control program 203 so that the control program 203 blocks the switch 206 located between the encoder 201 and the sound source storage unit 205. The sound source coming into the 201 stops being stored in the sound source storage unit 205.

When the user finishes recording the sound source or the like in the user terminal 10, the sound source providing server 30 ends the call.

3 is a diagram illustrating a step-by-step method of storing a sound source or the like to be used as an incoming call ring instead of a telephone ringing tone to a user terminal of another person through a sound source providing server.

When the sound source providing server 30 calls another user's user terminal 10, the sound source providing server 30 may select a predetermined DTMF that is activated in advance to activate the DTMF detector 202. When the DTMFs exchange with each other, the DTMF detection mode of the DTMF detector 202 is activated. After the DTMF detection mode is activated, the method of storing the sound source in the user terminal 10 is the same as that of FIG. 2, and the method shown in FIG. 3 can be used for additional service operations such as operating a membership service and sending a ringtone to another person.
