[0033]
FIG. 3 is a flow chart for illustrating a method for controlling background music play device according to a first preferred embodiment of the present invention. [0034]
As shown in FIG. 3, once the mobile station equipped with the background music play device is requested to make a communication channel establishment at step [0035] 301, the microcomputer 207 determines if music is being played or not at step 302. If no music is being played, a normal communication channel establishment process is performed. If music is being played, it is determined whether to stop the music during the voice communication according to the user's button manipulation or a preset algorithm at step 303.
If it is determined to continuously play music during the voice communication, it is determined whether the mobile station transmits the music to the counterpart mobile station together with the voice at step [0036] 304. In music play mode, whether the music to be transmitted or not can be determined automatically or by the button manipulation.
If it is determined not to transmit the music, sound volume is lowered to a predetermined level during the voice communication without transmitting the music at step [0037] 305. While, if it is determined to transmit the music to the counterpart mobile station, the sound volume is lowered to the predetermined level and the music is transmitted to the counterpart mobile station in the lowered volume level during the voice communication at step 305 a.
Consequently, it is determined whether the voice communication is finished at step [0038] 306, and the sound volume is recovered if the voice communication is finished at step 307.
At step [0039] 303, if it is determined to stop playing music, the microcomputer 207 records information on a point in time where the music is stopped on starting the voice communication or the music itself into a memory at step 303 a and then stop playing music at step 303 b. Consequently, the voice communication continues without playing music at step 305 b and then it is determined whether the voice communication is finished or not at step 306 a. If the voice communication is finished, the music is replayed from the position where the music stopped or from the beginning of the music on the basis of the information recorded in the memory at step 307 a.
At step [0040] 303 a, it is preferred that the point where the music is stopped is the time when the phone rings.
In this way, it is possible to have a conversation while listening to the background music. [0041]
The background music playing method according to a second preferred embodiment of the present invention will be described with reference to FIG. 4 hereinafter. [0042]
In the second preferred embodiment of the present invention, the background music play device can be set in such a way that the background music is played only when communicating with a mobile station having one of preset phone numbers. [0043]

[0044]
FIG. 4 is a flow chart for illustrating a background music play method according to another preferred embodiment of the present invention. [0045]
Firstly, specific phone numbers are preset for playing the background music only when the mobile station is requested to make a communication channel with the mobile station having one of the preset phone numbers at step [0046] 401. After the preset is finished, if the mobile station is requested to make the communication channel at step 402, it is determined if the phone number of the counterpart is one of the preset numbers at step 403. If it is determined that the number of the counterpart is not one of the preset numbers, the voice communication is performed without the background music at step 404 a. While, if it is determined that the number of the counterpart is one of the preset numbers at step 403, the mobile station plays the background music and transmit the music to the counterpart at step 404.
The background music play device can be installed to and uninstalled from the mobile station and can download and play music files provided by service providers. [0047]
Also, the music can be selectively played among the music files stored in the memory, and the background music can be automatically selected according to the phone number of the counterpart user. As explained above, the background music can be selectively played according to the phone numbers when the mobile station required to make a communication channel establishment and the background music can be selected among the music files stored in the memory by the user, and the background music can be randomly selected according to the phone number of channel establishment requester. Also it is possible to set so as to select and play a music file as a background music during the voice communication when the input number for requesting the communication channel establishment is one of the preset numbers. The point to begin playing the background music is when the communication channel is established. [0048]
As described above, in the mobile station equipped with the background music play device, the background music can be heard during the voice communication by the two communicators such that the background music help the conversation to be smooth and comfort, resulting in enhancing communication quality. Also, since the background music play method for mobile station of the present invention can play background music automatically, make possible to have conversation while the music is being played, and keep playing music after the communication channel is released, it can satisfy the various user requirements.
