Description

Receiving confirmation device of mobile communication terminal {DESTINATION CONFIRMATION APPARATUS OF MOBILE PHONE}

The present invention relates to a mobile communication terminal, and more particularly, to an incoming confirmation device of a mobile communication terminal for confirming to a user that a call signal from a base station for information reception, that is, information, has reached the mobile communication terminal.

A mobile communication terminal, i.e., a mobile phone, is a kind of information and communication new media developed so that information can be transmitted anywhere and at any time.

1 is a block diagram schematically showing the configuration of a conventional cellular phone.

In the conventional mobile phone 10, an antenna 11 is formed in the main body (not shown) to radiate or absorb high frequency radio signals into a space, and the antenna 11 has a diplexer constituting a bidirectional communication path. (12) is connected. Transmitter 14 and receiver 15 are connected to diplexer 12, respectively. The transmitter 14 amplifies the voice signal input from the microphone 13, modulates the signal into a high frequency band, and transmits the signal to the antenna 11 via the diplexer 12. The receiver 15 receives the antenna 11 The amplified signal received from the high frequency via the diplexer 12 is amplified, and then demodulated to an audible frequency band and transmitted through the speaker 16. Transmitter 14 and receiver 15 exchange signals with a base station. The control unit 18 is connected via a logic circuit unit 17 that is responsible for audio exchange. The incoming call display unit 20 generally includes a light emitting diode for visually displaying the incoming call state, an audible call tone generator for audible display, a liquid crystal display panel for displaying a phone number of the other party, and the like. On the other hand, a keypad 19 connected to the control unit 18 is formed in the main body, and the keypad 19 is formed with a dial button and a function button.

On the other hand, when a call is received by the mobile phone or data is received, the mobile phone user can hear that the call is received by the incoming display unit 20 or watch the operation of the light emitting diode to know that the call is received.

By the way, according to the conventional mobile phone, since the mobile phone user can know that the call is received only by the display of the incoming call display unit, if the mobile phone is outside the area where the user can recognize the display of the incoming call display unit, such as the inside of the bag or handbag, There is a problem that the user of the mobile phone does not know that the call is received by not hearing the ringing tone or not seeing the operation state of the LED.

Thus, an auxiliary device for a mobile phone has been developed that enables a mobile phone user to know that a call is received even when the mobile phone is out of an area capable of recognizing a display of an incoming call display.

Such a mobile phone assistant is described in detail in Korean Patent 1998-034287 (1998. 08. 24).

Referring to FIG. 2, the mobile phone auxiliary device 40 includes an auxiliary antenna 42 for absorbing an incoming signal emitted from the main body 21 in one region of the auxiliary casing 41. The auxiliary signal antenna 42 is connected with an incoming signal receiver 43 for receiving and processing incoming signals. At the other end of the incoming signal receiving unit 43, an auxiliary incoming call display unit 44 for displaying a reception state of the incoming signal is connected. The auxiliary incoming call display unit 44 is a visual display means such as a motor driving unit, a vibration motor, a light emitting diode, and a ringing tone. It can be implemented using an acoustic display means such as a generator.

On the other hand, the mobile phone 20 has a selection key (not shown) that allows the user to select any one of the operations of the incoming signal transmitting unit 43 and the incoming display unit 44 in addition to the existing configuration, and when a call is received from the other party. The incoming signal transmitter 22 and the auxiliary antenna 23 are provided to generate an incoming signal having a predetermined frequency and to transmit the received signal to the space.

The cellular phone auxiliary device 40 generates an incoming signal having a predetermined frequency in the incoming signal transmitter 22 under the control of the control unit 29 when a call is made to the cellular phone 20 to generate the auxiliary antenna 23. When radiating through, the incoming signal reception unit 43 receives the incoming signal through the auxiliary antenna 42 so as to display the incoming call to the auxiliary incoming display unit 44.

However, such a conventional mobile phone auxiliary device does not operate independently, and it is not possible to operate in a state in which the mobile phone is turned off because the presence or absence of incoming calls can be confirmed through the incoming signal received through the mobile phone.

Therefore, an object of the present invention is to solve the above problems, by receiving a call signal transmitted from the base station irrespective of the mobile phone to indicate that the call signal is received by the independent operation regardless of the state of the mobile phone user always The present invention provides a convenience to a user by checking whether a call and data received by a mobile phone are received.
