For example, the BBA2.X (Q5312CDMA) one-chip manufactured by Qualcomm of the United States and the RF unit can be manufactured.

Meanwhile, the controller 120 analyzes a command provided from the key input unit 150 and generates control signals corresponding thereto to control the overall operation of the system. In addition, by analyzing the forward channel data message received through demodulation, deinterleaving and decoding, data signal processing and vocoding of the digital signal output from the RF transmitter / receiver 110 and controlling each unit and performing a reverse function thereof. do. For example, the decoded digital voice data is output to the voice signal processor 130, and the digital voice data output from the voice signal processor 130 is encoded to be transmitted to the reverse channel through the RF transmitter / receiver 110. do. In addition, when the received forward channel data message is a message related to the incoming call, the incoming alarm mode set in the internal memory is analyzed to alert the user to the incoming call state. The control unit 120 may use the "MSM3300" supplied in the form of a chip from the US Qualcomm (QUALCOMM).

The voice signal processor 130 converts the digital voice data output from the controller 120 into an analog signal and transmits it to the outside through the speaker SPK, and digitally converts the voice signal input through the microphone MIC. Output to the controller 120. The display unit 140 includes an LCD and an LCD driving unit, and displays various operation states, transmission and reception messages, and the number of incoming and outgoing calls of the mobile phone under the control of the control unit 120. The key input unit 150 includes a plurality of numeric keys and function keys for performing various functions. When the function keys are pressed, the key input unit 150 generates key data and outputs them to the controller 120.

The power supply unit 160 includes a battery for supplying the operating power of the portable wireless terminal, and a DC / DC converter for converting the output voltage of the battery into a plurality of voltage levels and supplying the respective voltage levels. The power supply path blocking unit 170 switches on / off the power supply path between the power supply unit 160 and the RF transmitter / receiver 110 under the control of the controller 120 to supply or cut power. The power supply path blocking unit 170 may be simply implemented as a transistor that is switched on / off according to the output level of the power supply blocking signal output from the controller 120.

The MP3 processing module 200 includes a CPU 220 for controlling music file reproduction, a memory 230 in which the music file is stored, and an MP3 decoder 210 for decoding the music file. The CPU 220 in the MP3 processing module 200 controls the reproduction of a predetermined music file by transmitting and receiving data with the control unit 120 in the mobile phone module 100.

Hereinafter, call blocking methods according to an exemplary embodiment of the present invention will be described with reference to FIGS. 2 and 3.

First, FIG. 2 illustrates a call blocking control flow chart according to an embodiment of the present invention. Referring to FIG. 2, the control unit 120 proceeds to step 310 if there is a menu key input through the key input unit 150 in step 300. To display the menu list on the display unit 140. When the menu list is displayed on the display unit 140 as described above, the user sets a desired function while sequentially changing menu items. Accordingly, the controller 120 checks whether the incoming call blocking mode is set in step 320, and if there is a setting of the incoming call blocking mode, the controller 120 proceeds to step 330. In step 330, the controller 120 checks whether there is an additional function execution input. In the embodiment of the present invention, the additional function execution input refers to a command for playing a music file. If there is no additional function execution input in step 330, the control unit 120 proceeds to step 340 to check whether there is a call blocking mode release command. If there is a release command, the flow proceeds to step 380 and the reception standby mode is terminated. Then, the call blocking control process according to the embodiment of the present invention is terminated. Go back to and check if there is additional function execution input again.

If there is an additional function execution input in step 330, the control unit 120 proceeds to step 360 and outputs a power supply cutoff signal. The power supply cutoff signal is applied to the power supply path blocking unit 170 to cut off the power supplied to the RF transmission / reception unit 110. Thereafter, the control unit 120 checks whether there is a call blocking mode release command in step 370, and returns to step 330 if there is no release command. In this case, if there is an additional function execution input, the control unit 120 continuously maintains the power-off state supplied to the RF transmitter / receiver 110 through step 360, as well as the CPU of the MP3 module 200 so that music files can be played. Control 220. As described above, when the additional function execution stop command is input in step 330 during call blocking mode setting, the controller 120 proceeds to step 340 to check whether there is a call blocking mode release command. If there is no release command, the process proceeds to step 350 and after returning to the receive standby mode, returns to step 330, and if there is an incoming call cancel mode command, proceeds to step 380. The reception standby mode in steps 350 and 380 indicates a state in which power is normally supplied to the RF transmitter / receiver 110.

As described above, in one embodiment of the present invention, by interrupting the power supplied to the RF transmitter / receiver 110 only during a period in which the additional function is executed under the incoming call blocking mode, the user can enjoy playing music without being disturbed by the incoming call. You can do it.

Meanwhile, FIG. 3 illustrates a call blocking control flowchart according to another embodiment of the present invention. Referring to FIG. 3, if there is a menu key input through the key input unit 150 in step 400, the controller 120 proceeds to step 410 and displays a menu list on the display unit 140. The controller 120 proceeds to step 420 and checks whether the incoming call blocking mode is set. If there is a setting of the incoming call blocking mode, the controller 120 proceeds to step 430 to switch to the incoming call blocking mode. In the incoming call blocking mode, incoming calls are not displayed to the outside. In other words, by keeping the silent and vibration-free state, the user can not know whether there is an incoming call. If there is an incoming call in the incoming call blocking mode, the controller 120 proceeds to step 450 and counts only the number of incoming calls, and displays only the number of incoming calls on the display unit 140 in step 460. The control unit 120 checks whether the incoming call blocking mode is released in step 470, and if there is a release input of the incoming call blocking mode, the control unit 120 switches to the reception standby mode in step 480, but if there is no release input of the incoming call blocking mode, the call is received until there is a release input. Only count the number of times and display the number of times.

That is, in the second embodiment of the present invention, even if the incoming call is made in the incoming call blocking mode, the incoming call warning is not issued, so that the user can listen to the music being played without being disturbed by the incoming call.

Meanwhile, the terms used herein are terms defined in consideration of functions in the present invention, which may vary according to the intention or custom of a person skilled in the art, and the definition should be made based on the contents of the present application. .
