The present invention relates to a ring tone selection of a mobile phone, and more particularly, to a method of selecting a ring tone of a mobile phone, which is suitable for enabling MP3 music to be selected as a ring tone of a mobile phone in an MP3 mobile phone having an MP3 player.

The mobile communication system is composed of a mobile station (hereinafter referred to as a mobile phone), a base station, a base station controller, and a mobile switching center, among which a mobile phone is a digital cellular network (DCN), a personal communication service (PCS). The base station changes the signal format between the mobile terminal and the base station controller so as to be suitable for the wireless link and the wired link. The base station controller serves as a means of access between each element of the base station and the cell operator. It performs monitoring functions such as base station operation management, service state management of hardware and software in base station, resource allocation and configuration for call traffic, information collection about base station operation, and sub-devices related to base station operation, monitoring and fixing. . The mobile switching center then configures an access point for user traffic between the base station controller management and the mobile communication network and the mobile switching center of the general telephone network or the same mobile communication system.

In general, a mobile phone is simply a bar-shaped bar shape, a flip type like having a lid on a bar-shaped keypad part, and a folding type to separate and fold the LCD (Liquid Crystal Display) part and the keypad part of the terminal. In recent years, there has been a watch phone that has a terminal in the form of a watch.

Such mobile phones were initially used only for voice communication, but recently, they are also used for data communication. Examples of such mobile phones are location information service using a mobile phone, and e-mail on the move using an Internet phone, which allows access to the Internet without a computer. It is also used for processing and electronic commerce (securities, tickets, train tickets, etc.).

In addition, recently, AM or FM radio broadcasts using a mobile phone or MP3 music (file extension mp3) downloaded from the Internet as an audio file format (file extension mp3) and stored in the mobile phone, and when necessary to play in various forms, such as Cell phones are being developed.

In such a mobile phone, when an incoming call is generated from an arbitrary counterpart, the mobile station modem of the mobile phone detects it and the mobile phone user recognizes it through a speaker or a buzzer.

Hereinafter, an apparatus for generating a ringing tone of a conventional mobile phone will be described with reference to the accompanying drawings.

Hereinafter, a configuration and an operation according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

Figure 2 is a block diagram showing a ring tone selection device of a mobile phone according to the present invention.

As shown in FIG. 2, the apparatus for selecting a ringing tone of a mobile phone according to the present invention includes a central processing unit (CPU), an encoder, an interleaver, a deinterleaver, and a Viterbi decoder. A mobile station modem 11 having a modulation / demodulation, vocoder function, and a first memory (e.g., a ringtone, etc.) required to operate the mobile phone. Flash memory) 12, a second memory (preferably SRAM) 13 temporarily storing data generated when the mobile phone is operated, and a speaker for outputting the voice of the other party ( 17) and a ringer 16 for generating a ringing tone when an incoming call occurs, a keypad 15 for transmitting a user's input command to the mobile station modem 11, and a display unit 14 for displaying the state and operation of the mobile phone to the user. )Wow, A memory device (for example, a multimedia card (MMC)) 22 storing an MP3 file, a decoder 23 for decoding an MP3 file of the memory device 22, and converting and amplifying the decoded signal And a signal converter (digital / analog converter (D / A converter)) 24 to be output to the speaker 17 and the MP3 file of the memory device 22 to the decoder 23. It is composed of a microcomputer (21). In this case, the microcomputer 21, the memory device 22, the decoder 23, and the signal converter 24 constitute the MP3 player 20.

At this time, MP3 is an audio file format created using audio data coding technology. It is a technology that can compress existing analog audio data into digital audio data of about one-twelfth without degrading the sound quality and is developed by the Motion Picture Experts Group (MPEG). Unlike digital CDs and cassette tapes, this digital music is the next generation of music produced in the form of computer files. You can listen to music through a computer instead of audio and copy it easily to a diskette or CD-ROM.

In terms of sound quality, it is comparable to existing CD recordings and has excellent compression ability, so it has the advantage of storing hundreds of songs on a single CD.

In order to use such MP3, we use exclusive software and portable player (hereinafter referred to as MP3 player) which is commercially available. Generally, dedicated software is developed by various software companies and distributed freely on the Internet. Anyone can easily operate the mouse.

MP3 players are about the size of a Walkman so you can carry MP3 files with you without a computer.

Recently, in order to store MP3 files in a mobile phone, a memory device is embedded in the mobile phone during the production of the mobile phone, and a MP3 file is downloaded and used in the Internet and PC communication using a receptacle.

Here, the receptacle is a cable for communicating with the Internet or PC using a mobile phone. One end of the receptacle is connected to the data communication terminal of the mobile phone (usually located at the bottom of the mobile phone), and the tile side is connected to the printer port of the computer. Or download MP3 music from PC communication to the memory device of the mobile phone.

In the mobile phone ring tone selection apparatus according to the present invention, the ring tone data stored in the first memory 12, which is the flash memory, is output to the ringer (or buzzer) 16 or the speaker 17 as in the related art. In the mobile phone with 3, MP3 music is output as ringtone data through the ringer 16 or the speaker 17, which will be described with reference to FIG.

FIG. 3 is a flowchart for explaining a ring tone selection method using the ring tone selection apparatus shown in FIG. 2.

If an incoming call is generated from a mobile phone having an embedded MP3 player from an arbitrary opponent, the MP3 mobile phone receives it (S0). At this time, the mobile station modem 11 detects the incoming call.

Subsequently, the mobile station modem 11 makes a bell selection determination for searching for a state of the ring mode of the current Amp3 mobile phone (S1).

If it is determined that the ringtone mode is selected as the ringtone stored in the flash memory of the first memory 12, the ringer 16 outputs the ringing sound through the ringer 16 or the speaker 17 in a conventional manner (S5).

However, if the MP3 music stored in the memory device S22 is selected (S1), the state of the MP3 player is determined (S2). At this time, the mobile station modem 11 transmits an instruction signal for determining the state of the MP3 player to the microcomputer 21.

Judgment result (S2) If the MP3 player is in the idle state (IDLE), since the current MP3 player is in operation (for example, the user is listening to music), the microcomputer transmits that the MP3 is in the idle state to the mobile station modem (S3). ).

The mobile station modem 11 then outputs the existing ringtone through the speaker. In this case, the MP3 mobile phone user may be listening to the MP3 music loudly, so that the mobile station modem 11 outputs the existing ringtone to the earphone 25 (S4).

However, if the MP3 player is in the sleep state (S2), the mobile station modem 11 notifies that the incoming call is received through the microcomputer 21 (S6).

Then, the microcomputer 21 reads the MP3 music data stored in the memory device MMC and transmits the MP3 music data to the decoder 23, and the decoder decodes the MP3 music data to the signal converter (D / A converter 24). Send it to)). Then, the signal converter converts the MP3 music data, which is a digital signal, into an analog signal, and then outputs the MP3 music to the earphone 25, the speaker 17, or the ringer 16 (S7).

Then, the user knows that the call has come (S8).

The ring tone selection method of the mobile phone according to the present invention as described above has the following effects.

First, since the user can download the music he wants and use the song as a ring tone, his music can be used as a ringtone.

Second, MP3 music is used as the ringtone, so you can change it at any time.
