Phone Bell Sounds Providing System and Method in Mobile Communication Value-added Services}

The present invention relates to a system and method for providing a ringtone sound source for a mobile communication additional service, and more particularly, a user of a portable terminal automatically receives a plurality of ringtone sound source files having the same song name but different playback intervals at a time. The present invention relates to a system and method for providing a ringtone sound source for a mobile communication supplementary service suitable for use as a ringtone.

Recently, with the development of technology in the mobile communication field, the spread of mobile terminals such as mobile phones, PDAs, DMBs, notebooks, etc. is continuously expanding, attracting new subscribers among mobile communication providers that provide mobile communication services, In order to continuously attract subscribers, various additional services are provided except voice or video call service.

Among the additional services related to the portable terminal, a ringtone service that edits and processes popular pop songs is most actively used.

The following describes a general ringtone service in service.

A mobile communication service provider providing a ringtone service extracts a sound source of a specific section of about 60 seconds from a general sound source file in an MP3 format. For example, the recent trend of Wonder Girls' Nobody extracts the most popular part of a song by about 60 seconds.

Subsequently, the mobile operator converts the extracted sound source into a format that can be reproduced by a portable terminal. In the AEC / AAC + and MMF formats which are standard codecs of MPEC, the extracted sound source is converted to a specific frequency (for example, 64 Kbps) in the entire frequency band. 11Kbps) to process the ringtone.

The mobile operator stores the converted sound source in the ringer server of the mobile operator. At this time, the data capacity of one ringtone sound source stored in the ringtone server of the mobile communication service provider is about 500KB.

Subsequently, when a user of a portable terminal wants to receive a ring service, the user accesses a ringer server of the mobile communication provider using a wired / wireless internet (or ARS), selects a desired sound source, Download it.

At this time, the ringer sound source down to the portable terminal is automatically set as the ringtone for the incoming call, or the user operates the keypad of his portable terminal to set the desired sound source as the ringtone for the call.

Therefore, when a user of another portable terminal makes a phone call to his or her portable terminal, a predetermined sound source is played on the called party's portable terminal until the call starts.

However, in the above-described conventional ringtone service, the lyrics and / or music of a ringtone sound source made by editing a specific ringtone song are the same.

Therefore, when there are a large number of users of a portable terminal having the same ringtone source set as a ringtone for a call in a certain area, the same ringtone source is often heard here and there simultaneously at similar times.

In such a case, there was a situation in which the incoming ringtones being played now were not easily judged by one's own or someone else's, and people around them could feel somewhat embarrassed or irritated.

In order to improve the shortcomings of the conventional ringtone service, the server of the mobile communication service provider cuts a single sound source into 60 seconds in length and edits and processes 2-3 ringtone source files for each section such as the first half, the second half, and the popular section. Service to provide commercialization.

Therefore, when the user of the portable terminal downloads the ringtone sound source, even if the ringtone sound source of the same music is downloaded, the ringtone sound source file having a different playback section is downloaded and used as a ringtone for an incoming call. Accordingly, the ringtone sound source having the same song name is used according to the personality and taste of the user of the portable terminal, and the ring tone sound source having the different song name is used as the ring tone for the incoming call. Could be

However, in the case of using the conventional improved ring service, it was not possible to simultaneously download a ringtone sound source having the same song name but different playback periods in the same music, and had to follow a separate download procedure if necessary, and accordingly, separately use information fees. Was added.

For example, if the ringer server of the mobile service provider provides three ringtone sound source files divided into a first half, a second half, and a popular section, the user of the mobile terminal may download all three files. The user of the portable terminal must execute three download procedures, and the information fee accordingly is added separately.

The reason for providing the ringtone service in the manner described above is that the data capacity of one ringtone sound source stored in the ringtone server of the mobile communication service provider is about 500 KB. When three ringtone sound source files are simultaneously received, the user of the portable terminal at once This is because the data capacity of the ringtone sound source to be downloaded is about 1.5MB, which slows down the download speed, and accordingly, the information fee is excessively charged.

An object of the present invention is to solve the problems of the prior art and the improved prior art described above, when a user of a portable terminal downloads a specific ringtone sound source, a plurality of ringtones having the same song name but different playback periods in the same music The present invention provides a ringing sound source providing system and method for a mobile communication additional service that can simultaneously download a sound source file.

Another object of the present invention is to compare the data capacity of a plurality of ringtone sound source files to be downloaded from a ringtone server of a mobile carrier when the user of the portable terminal simultaneously downloads a plurality of ringtone sound source files having the same song name but different playback intervals. The present invention provides a system and method for providing a ringtone sound source for a mobile communication additional service that can be downloaded at a relatively faster speed than the related art and thus reduce information usage fee.

The ringtone sound source providing system for mobile communication additional service according to the present invention for achieving the above object,

Computer equipped with Digital Spectrum Sampler (11) which processes the frequency band and size of the ringtone sound source by varying the sampling rate of the ringtone sound source and compresses the processed ringtone sound source in MP3 or AAC / AAC + format. System 10;

The portable terminal is connected to the computer system 10 through the Internet 20, and stores a plurality of ringtone sound source files generated by the computer system 10 under the control of the digital sound source system 30, respectively. Ringer server 40 of the mobile communication provider to selectively provide the stored ringtone sound source file at the request of;

When connected to the Internet 20 or the mobile communication network 60, the download of the ringtone sound source having a specific song name, consists of at least one portable terminal 50 to download the ringtone sound source,

When the user of the portable terminal 50 accesses the ringtone server 40 through the Internet 20 or the mobile communication network 60 and selects and downloads a specific ringtone sound source, the ringtone server 40 is configured to perform the download. A ringtone sound source selected by the user and a ringtone sound source file identical to the file name of the selected ringtone sound source but different in playing period are also transmitted to the portable terminal 50.

In addition, a method for providing a ringtone sound source for a mobile communication additional service for achieving the above object, in a computer system with a built-in sound source editing program, a plurality of ringtones for each particular section so as to have a specific playback time length from a specific ringtone song stored in a storage medium Extracting sound sources (S101);

In a computer system in which a sound source editing program is embedded, editing and processing the extracted ringtone sound source by variably applying a sampling rate to match the playback characteristics of a playback device (S102);

Compressing each ringtone sound source in an AAC / AAC + format in a computer system in which a sound source editing program is embedded (S103);

An operation of the computer system storing the compressed plurality of ringtone sound source files in a ringtone server of a mobile communication operator (S104);

A user of an arbitrary portable terminal accessing the ringer server of the mobile communication company, selecting a ringtone sound source file of a specific song name, and executing a download (S104);

The mobile phone's ringer server may be configured to transmit the ringtone sound source selected by the user and a plurality of ringtone sound source files having the same song name but different playback intervals to the portable terminal (S105).

According to the above-described system and method for providing a ringtone sound source for a mobile communication additional service according to the present invention, a plurality of ringtone sound source files having the same song name but different playback periods in the same music in a ringtone server of a mobile communication company have relatively smaller data than before. When the user of the portable terminal downloads the ringtone sound source file of a specific song name, the user of the portable terminal downloads a plurality of ringtone sound source files having the same song name but different playback intervals through a single download procedure. Can be stored to improve usability.

In addition, when editing and processing each ringtone sound source stored in the ringtone server of the mobile communication operator, the sampling rate is variably applied in consideration of the playback characteristics of the portable terminal, thereby making the compressed data size relatively smaller than before. Since the user of the portable terminal downloads a plurality of ringtone sound source files having the same song name but different playback intervals in the same music through a single download procedure, they can be downloaded at a relatively faster speed than before. The fee for use can also be reduced than before.

1 is a block diagram of a ringtone sound source providing system for a mobile communication additional service according to the present invention. Referring to FIG. 1, a ringtone sound source providing system for a mobile communication additional service according to the present invention processes a frequency band and a size of a ringtone sound source by applying a sampling rate to a ringtone sound source, and converts the processed ringtone sound source to an MP3 or AAC. A computer system (10) having a Digital Spectrum Sampler (11) for compressing in / AAC + format;

The digital sound source system 30 is connected to the computer system 10 through the Internet 20, and controls the upload, deletion, or management of the ringtone sound source file created by the computer system 10 under the control of the operator. and;

It is connected to the computer system 10 through the Internet 20, and stores a plurality of ringtone sound source files made by the computer system 10 under the control of the digital sound source system 30, respectively, according to the request of the authenticated portable terminal A ringtone server 40 of a mobile communication provider for selectively providing a stored ringtone sound source file;

When connected to the Internet 20 or the mobile communication network 60, and downloads the ringtone sound source having a specific song name, it is composed of at least one portable terminal 50 to download the ringtone sound source.

Here, the digital spectrum sampler 11 of the computer system 10 uses a built-in sound source editing program (for example, SoundForge, etc.) to record about 60 seconds of a ringtone song stored in a storage medium (for example, CD, USB). The ringtone sound sources are extracted for each section (eg, first half, second half, popular section, etc.) by length.

The digital spectrum sampler 11 of the computer system 10 compiles and processes a variable sampling rate for each of the extracted ring tone sources. That is, the frequency region in which the portable terminal is difficult to reproduce the ringtone sound source is edited and processed by using a variable sampling method that reduces the sampling degree as much as possible and increases the sampling degree in the well reproduced region.

In addition, the digital spectrum sampler 11 of the computer system 10 compresses the processed ringtone sound source in the MP3 or AAC / AAC + format, respectively, for playback on the portable terminal 50.

The digital sound source system 30 manages a plurality of ring sound sources stored in the ringer server 40 of the mobile communication company as a file name. The file name indicates a playback section using parentheses or an extension.

For example, in the case of a Wonder Girl's nobody song, the nobody (first half) .mp3, nobody (second half) .mp3, nobody (population) .mp3, etc., simultaneously display a playback section in the file name and parentheses that indicate the name of the song.

Therefore, when the user of the portable terminal 50 accesses the ringer server 40 of the mobile communication service provider through the Internet 20 or the mobile communication network 60, and searches for a specific song name to receive the ringtone service, the digital sound source system 30 ) Shows all ringtone music files with the same song name but different playback periods.

In addition, when a user of the portable terminal 50 selects a ringtone sound source file of a specific song name and executes a download procedure, the ringer server 40 of the mobile communication company may have a ringtone sound source file having the same song name but different playback period. If present, all of the ringtone sound source files selected by the user are transmitted to the portable terminal 50.

Hereinafter, a ringtone sound source service procedure for a mobile communication additional service according to the present invention will be described in detail with reference to FIGS. 1 to 3.

The ringtone sound source service procedure for the mobile telecommunication supplementary service according to the present invention is largely (1) a procedure for creating and storing a plurality of ringtone sound sources in a ringtone server of a mobile carrier, and (2) a user of a specific portable terminal downloads a specific ringtone sound source file. It is divided into procedures.

(1) ringtone sound production procedure (see Fig. 2)

In general, a ringtone song stored on a storage medium is a source file sampled at 44.1 KHz. Using the sound source editing program, the operator of the computer system 10 cuts a specific ringtone song stored in a general storage medium into specific sections (for example, first half, second half, popular section, etc.) to have a length of about 60 seconds, and then, by section. Each cut ringtone sound source is extracted (S101).

Subsequently, the extracted ringtone source is edited and processed by variably applying a sampling rate so as to be optimal for the reproduction characteristics of the portable terminal 50 such as a mobile phone, a PDA phone, a DMB phone, a notebook computer, and the like (S102).

In general, since the portable terminal is designed to reproduce the human voice best, the portable terminal performs well in the 10Hz to 1KHz band, which is a frequency corresponding to the voice of a universal user.

However, a typical melody song contains relatively wide frequency components of about 20Hz to 10KHz, as well as songs from human voices, as well as performances from various instruments.

Accordingly, in the preferred embodiment of the present invention, when the operator edits and processes the ringtone sound source, the frequency region in which the portable terminal is not played well decreases the sampling degree, and the frequency region in which the portable terminal plays well increases the sampling degree. Use a variable sampling method.

Therefore, it is made of a ringtone sound source having a better sound quality even with a relatively small data capacity than the conventional MP3, AAC / AAC + format.

For example, in the step of extracting a sound source from a specific ringtone song to edit and process it as a ringtone sound source, conventionally, a specific ringtone song was processed into a ringtone sound source by applying a fixed sampling rate of 64 Kbps to 80 Kbps in all frequency bands.

However, in the embodiment of the present invention, the frequency band of the ringtone song is reproduced at 128 Kbps at 100 Hz to 1 KHz, 32 Kbps at 50 Hz to 10 Hz, 8 Kbps at 50 Hz or less, 64 Kbps at 1 KHz to 3 KHz, 32 Kbps at 3 KHz to 5 KHz, and 8 Kbps at 5 KHz or higher. Edit and process by applying variable sampling rate of optimal state to characteristic

In the step of editing and processing the ringtone song by applying such a variable sampling method, when a popular song of about 60 seconds is sampled in the AAC format, it has a data capacity of about 500 KB or more, but in the embodiment of the present invention, it is variable. By applying the sampling method, it has a data capacity of about 400KB smaller than the conventional one.

Subsequently, the ringtone sound source is compressed into a format such as AAC / AAC + that can be reproduced by the portable terminal (S103).

Subsequently, the operator of the computer system 10 controls the digital sound source system 30 to store the compressed ringtone sound source files in the ringtone server 40 of the mobile communication operator, respectively (S104).

At this time, the digital sound source system 30 manages a plurality of ringtone sound source files having the same song name but different playback periods by the file name indicated by the playback section, and when the user of the portable terminal 50 searches for a specific song name, Shows all ringtone source files with the same song name but different playback intervals.

Therefore, when the user of the portable terminal 50 selects a ringtone sound source file of a specific song name and executes the download (S105), the ringer server 40 of the mobile communication company has the same song name as the ringtone sound source selected by the user but has a different playback section. A plurality of ringtone sound source files are also transmitted to the portable terminal 50 (S106).

At this time, if the user of the portable terminal simultaneously downloads three ringtone source files in which a specific ringtone song is divided into three playback sections, the total data capacity of the three sections is about 1.2MB. Even if executed, the ringer server 40 of the mobile communication provider can transmit the entire data of three sections at once.

(2) ringtone sound source download procedure (see Fig. 3)

Hereinafter, a case in which the user of any portable terminal 50 shown in FIG. 1 uses the ringtone sound source service for mobile communication additional service according to the present invention will be described.

First, a user of an arbitrary portable terminal 50 connects to a ringer server 40 of a specific mobile communication provider (for example, Nate, Magic N, Easy Eye, etc.) using his portable terminal (or computer) ( S201).

When the user of the portable terminal 50 searches for the desired ringtone sound source, the ringtone server 40 of the mobile communication operator shows the ringtone sound source searched by the user and the ringtone sound source having the same file name but different playback intervals (S202). .

Subsequently, the user of the portable terminal 50 selects a desired ringtone sound source (S203).

In this case, the ringer server 40 of the mobile communication service provider includes a ringtone sound source selected by the user and a plurality of ringtone sound source files having the same song name but different playback intervals in the same music through the mobile communication network 60 (or the Internet 20). The mobile terminal 50 transmits the data to the portable terminal 50 (S204).

Therefore, even when the user of the portable terminal 50 executes one download procedure, the user of the portable terminal 50 simultaneously stores two or three ringtone sound source files having different playback sections such as the first half, the second half, and the popular section (S205).

In this case, the portable terminal 50 automatically sets the ringtone sound source file (for example, a popular section file) to be stored as the ringtone for the incoming call, and the user may set a new ringtone for the incoming call if necessary.

Therefore, when a user of another portable terminal makes a call to his portable terminal 50, the called party's portable terminal 50 is played until the ring tone sound source set as the incoming ring tone is started.
