Abstract

PURPOSE: An apparatus and method for reporting the establishment of a call in a mobile station is provided to use the vibration device of a mobile station in informing the user that a call has been established with the opposite party. CONSTITUTION: If a user executes dialing in a call standby state(300), a control part detects the dialing operation(310) and analyzes the dial data received from a data processing part(320). If a call establishment signal is generated as a call with a called subscriber has been established, the control part detects the call establishment signal(330) and makes a vibration device work for 2-3 seconds(340). The operation of the vibration device makes the user recognize that the call has been established. The user executes a call function with the opposite party as a voice traffic path is formed through an audio processing part(350).

DETAILED DESCRIPTION A detailed description of preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

The present invention relates to an apparatus and method for notifying a user that a call is formed when a call is made with a counterpart by using a vibration device in a mobile phone.

1 is a diagram showing the configuration of a telephone for a mobile phone according to an embodiment of the present invention.

Referring to FIG. 1, the keypad 100 includes keys for inputting numeric and text information and function keys for setting various functions.

The memory 110 may be composed of a program memory and a data memory. The program memory may store programs for controlling a general operation of the portable telephone, and the data memory temporarily stores data generated during the execution of the programs.

The display unit 120 displays the state being performed under the control of the controller and the key manipulation state of the user when the call function is performed. The vibration device 130 performs a vibration function under the control of the control unit 200 when in the incoming mode and when a call is formed with the other party.

The data processor 140 includes a transmitter for encoding and modulating the transmitted signal and a receiver for demodulating and decoding the received signal. That is, the data processor 23 may be configured of a modem and a codec CODDEC.

The audio processor 150 reproduces the received audio signal output from the data processor 140 or transmits a transmission audio signal generated from the microphone to the data processor 140. The first amplifier 160 amplifies the input and output signals of the microphone, the second amplifier 170 amplifies the input and output of the speaker.

The RF unit 190 performs communication of the portable telephone. The RF unit 190 includes an RF transmitter for upconverting and amplifying a frequency of a transmitted signal, and an RF receiver for low noise amplifying and downconverting a received signal. The third amplifier 180 amplifies the voice signal and the various data transmitted and received by the RF unit 190.

The controller 200 performs a function of controlling the overall operation of the portable telephone. In addition, the controller 200 may include the data processor 140. In addition, the control unit 200 has a built-in call notification function, and performs a function to control the vibration device 130 by detecting a call forming signal when forming a call with the other party.

Looking at the operation of the portable telephone with reference to Figure 1, when the user performs a dialing operation through the keypad 100 when the call is set, the dialing mode, the control unit 200 detects the dial information received through the data processor 140 After processing the RF signal through the RF unit 190 and outputs. Thereafter, when the counter subscriber generates a response signal, the counter subscriber detects the response signal through the RF unit 190 and the data processor 140. Thereafter, a user establishes a voice call path through the audio processor 150 to perform a communication function. In addition, in the incoming mode, the controller 200 detects the incoming mode through the data processor 140 and generates a ring signal through the audio processor 150. Thereafter, when the user responds, the controller 200 detects this, and a voice call path is formed through the audio processor 150 to perform a communication function. In the outgoing and incoming modes, voice communication is described as an example, but a data communication function for communicating packet data and video data may be performed in addition to the voice communication. In addition, when performing a standby mode or text communication, the controller 200 displays text data processed by the data processor 140 on the display 120.

2 is a flowchart illustrating a method for notifying that a call is formed in a cellular phone according to an embodiment of the present invention.

Embodiments of the present invention will now be described in detail with reference to FIGS. 1 and 3.

First, when the user performs a dialing operation through the keypad 100 to perform a call in step 300 in the call connection standby state, the controller 200 proceeds to step 310 to determine this.

In step 310, the controller 200 that detects a dialing operation of the user analyzes dial information received through the data processor 140.

In this case, if the received dial information is call request data, the MS (user) outputs the dial information through the access channel in step 400, and the MS (user) converts the signal of the access channel into an RF signal through the RF unit 190. It converts and outputs it to base station BS.

In step 410, the base station BS, which is requested to call the MS (user), allocates a traffic channel to the MS (user) through the paging channel. In step 410, the MS (user) assigned the channel responds to the channel assignment to the base station (BS) in step 420.

In step 430, the base station (BS) transmitting a response from the MS (user) transmits information of the calling party and the called subscriber to the MSC, and accordingly, the MSC performs step 440. Generates a message integrating the information of the called subscriber and transmits it to the mobile communication switch at the called party.

After the MSC transmits a message integrating the recipient's information to the MS on the called party's side, the MSC alerts the BS to the BS in step 450. Send it.

In step 460, the base station BS, which has received the ALERT from the MSC, turns on the ALERTING to the MS (user).

In the state in which the base station MS has turned on the ALERINGT to the MS (user), the mobile communication exchange of the called party is connected to the MSC in step 470. When notifying, the MSC notifies the base station BS that the call of the called subscriber is connected in step 480.

In step 490, the base station BS turns off the ALERTING of the MS (user) and forms a call with the called party.

In step 490, when an alarm tone is turned off and a call is made with an incoming subscriber and a call formation signal is generated, the controller 200 detects this.

In step 330, the control unit 200 that detects a call formation signal with the called subscriber controls the vibration device 130 to operate for 2 to 3 seconds in step 340.

In operation 340, the user may recognize that a call is made with the counterpart by the operation of the vibrator 130. In operation 340, a voice call path is formed through the audio processor 150 to perform a call function with the counterpart.

When the execution of the call function in step 350 is finished, in step 360, the controller 200 switches back to step 300 in the call connection standby state.

That is, as described above, when the user makes a phone call using a mobile phone having a vibration function, the user may know that the call is formed without listening to the speaker until the call is made with the other party. have.
