Hereinafter, with reference to the accompanying drawings a preferred embodiment of a reception detection wireless signal transmission / reception apparatus of a mobile phone according to the present invention will be described.

Figure 2 is a block diagram of a mobile phone and an incoming call detection wireless signal receiving apparatus according to the present invention.

As shown in FIG. 2, when an incoming signal transmitted from a base station (not shown) is received, the bell output unit 20 or the vibrating unit 30 is selectively controlled according to the incoming mode, and at the same time, the radio signal transmission control signal is controlled. A wireless signal transmitter 40 for transmitting a signal indicating that an incoming signal is currently coming to the mobile phone 50 in response to a generated control unit 10, a control signal output from the control unit 10, and the wireless Receiving a wireless signal output from the signal transmission device 40 consists of a wireless signal receiving device 90 for notifying the user of the incoming call with visual and vibration.

FIG. 3 is a detailed block diagram of the wireless signal transmitter of FIG. 2.

As shown in FIG. 3, the radio signal transmitter 40 may include a code generation unit 40-1 that receives an incoming signal output from the controller 10 and generates a code corresponding to radio data; The modulator 40-3 receives the code outputted from the code generator 40-1 and modulates the analog carrier, and generates a frequency by receiving the carrier outputted from the modulator 40-3.
