First, FIG. 2 is a diagram illustrating a process of downloading a background sound from a background sound storage server. The user selects a desired background sound by using an input unit 180 such as a keypad and an output unit 170 such as an LCD. The processor 110 embedded in the mobile communication terminal 100 accesses the background sound storage server 400 via the mobile communication base station 300, downloads the desired background sound, and stores the desired background sound in the sound source storage unit 130. Here, the background sound storage server 400 is a server that stores sound content for use as a background sound during a call, and the sound source can be continuously updated by a server administrator.

3 is a diagram illustrating a background sound transmission method according to the present invention. The mobile communication terminal includes a transceiver 120 for communicating with the mobile communication base station 300, a sound source storage unit 130 for storing sound sources such as a background sound, an effect sound, a ringtone, and a melody IC for reproducing a sound source coded in a specific manner. 140, a speaker 150 for converting an electric voice signal from the receiving side into a sound, a microphone 160 for converting a voice of a talker into an electric signal, an output unit 170 such as an LCD, an input unit 180 such as a keypad, and the like. ), And a central processor 110 connected thereto. The processor 110 performs overall processing for mobile communication functions such as protocol, voice coding, and data processing of the mobile phone. To this end, the processor 110 receives a voice signal and also includes a data processor 112 for digital data calls in addition to the voice processor 111 including a codec module for transmitting and receiving voice, such as EVRC, AMR, etc. according to a mobile phone standard. Include. In the alternative, the data processor 112 may be implemented separately from the processor 110 to transmit the background sound from the sound source storage 130 to the data channel.

3 and 5, the background sound transmission method according to an embodiment of the present invention will be described.

In step 510, the mobile communication terminal waits until there is a predetermined input in the standby mode. If any input is given through the input unit 180, it is determined in step 520 whether the input is a background sound transmission (transmission) command. If it is not a background sound transmission command, the process returns to the standby mode. In the case of a background sound transmission command, in step 530, the user selects a desired background sound from the sound source storage unit 130 through the input unit 180 and the output unit 170 of the mobile communication terminal 100. For example, the user selects a desired background by combining keys of the keypad with reference to the information displayed on the LCD. In operation 540, the central processor 110 receives background sound setting state information for confirming whether the background sound is set by the receiving terminal 200 before transmitting the selected background sound. The transmitting terminal 100 transmits the background sound setting state confirmation request signal to the receiving terminal 200 via the mobile communication base station 300, and the receiving terminal 200 transmits the background sound setting state information in response thereto. It may be made by transmitting to the side mobile communication terminal 100. In step 550, the central processor 110 determines whether the background sound is set in the receiving terminal 200 from the background sound setting state information transmitted from the receiving terminal 200. If the background sound is not set in the receiving terminal 200, in step 560, the central processor 110 performs mobile communication through the transceiver 120 of the selected background sound stored in the sound source storage unit 130. The data channel is transmitted to the base station 300. In addition, the mobile communication base station 300 transmits the background to the receiving terminal 200 through the data channel. If it is determined in step 550 that the background sound is set by the receiving terminal 200 itself, the process ends without transmitting the background sound to the receiving terminal 200.

Here, the background sound may be transmitted at the same time that the processor 110 transmits the user's voice through the voice channel. Alternatively, the background sound may be first transmitted to the receiving terminal 200 at a high speed and then received when the user calls. The side terminal 200 may be implemented to reproduce itself.

Meanwhile, the receiving terminal 200 decodes and reproduces the digital sound source transmitted through the data channel by a melody IC, and then synthesizes the reproduced digital sound source and the voice call sound source and outputs it to the speaker.

Here, the communication between the mobile communication base station 300, the transmitting terminal 100 and the receiving terminal 200 is made according to international standards of mobile phones such as IS-95, CDMA-2000, WCDMA.
