Abstract

PROBLEM TO BE SOLVED: To evade the troublesomeness of key input operations and to improve the operability of a schedule book function by changing key input and LCD output in the schedule book function for reporting a set message at the set time to voice input/output in a portable telephone. SOLUTION: A voice message is stored in a memory 22 as signals compressed by a voice compressor 15 and the set time data are simultaneously stored in the memory 22. When a microcomputer 18 recognizes that the set time comes by a time recognition means 19, it is reported to a user by a reporting means 12. When the user requests the reproduction of the message from a key pad 13, the microcompuer 18 reproduces the message by transmitting the compressed voice message stored in the memory 22 by a voice expander 14.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a mobile terminal in a mobile communication system.

[0002]

2. Description of the Related Art In the field of mobile phones, in addition to the original call function, it is becoming more important to provide additional functions such as a function for storing voice during a call, a clock function, and a calculator function. . Focusing on the portability of a mobile phone, a mobile phone having a schedule book function for displaying a promised content and a message on an LCD at a set time has been released as a product.

[0003]

In the conventional schedule book function, time setting and message input are performed by key operation, so that key operation particularly when inputting a long message becomes complicated and time-consuming. .

[0004]

FIG. 1 is a block diagram showing the operating principle of the schedule function according to the first aspect of the present invention.

The voice signal input from the microphone 4 is A / D
The audio signal is converted into a digital signal by the converter 11, and the audio compressor 1
5 is sent. This compressed audio signal is stored in the memory 22.
And the time data is also stored in the memory 22.
When the time recognizing means 19 detects that the set time has been reached by the microcomputer 18, the notifying means 12 notifies the user. User plays message on keypad 1
When requested from 3, the microcomputer 18 transmits the compressed audio signal to the audio decompressor 14. The expanded digital signal is converted by the D / A converter 10 and supplied to the receiver 3 as an audio signal.

By changing the message input / output of the mobile phone having the schedule book function from the key input and LCD display to the voice input / output, the complexity of the key operation is avoided and the operability of the schedule book function is improved.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a block diagram of a TDMA digital mobile phone. The baseband circuit 1 surrounded by a dotted line in FIG. 2 will be described. Reference numeral 10 is a D / A converter, 11 is an A / D converter, 12 is a notification means, 13 is a key pad which is an interface with the user, 14 is a voice expander,
Reference numeral 15 is a voice compressor, 16 is a channel decoder, 17 is a channel encoder, 18 is a microcomputer for controlling a mobile phone, 1
9 is a time recognition means, 20 is a demodulator, 21 is a modulator, 22
Is a memory.

Reference numeral 2 is an RF circuit, 3 is a receiver, and 4 is a microphone.

Next, detailed operation of the circuit of the embodiment will be described.

In FIG. 2, during a normal call, the voice signal input from the microphone 4 is converted into a digital signal by the A / D converter 11 and supplied to the voice compressor 15. The audio signal compressed by the audio compressor 15 is added with control bits by the channel encoder 17 and transmitted to the modulator 21.
The signal modulated by the modulator 21 is transmitted to the RF circuit 2 and further wirelessly transmitted to the base station. The signal received by the RF circuit 2 is input to the demodulator 20 and demodulated. The demodulated signal is transmitted to the channel decoder 16,
The control signal is separated and transmitted to the voice expander 14. The signal expanded by the audio expander 14 is D / A converted by the D / A converter 10.
It is A-converted and transmitted to the receiver 3.

When the user requests storage of a voice message from the keypad 13 when using the schedule book function, the microcomputer 18 stores the compressed voice signal and the set time data in the memory 22. When the microcomputer 18 recognizes that the set time has come by the time recognition means 19, the notification means 12 is used to notify the user. When the user requests the reproduction of the message from the keypad 13, the microcomputer 18 transmits the compressed voice signal from the memory 22 to the voice expander 14, and the signal after the voice is expanded is passed through the D / A converter 10 to the receiver 3 Sent to and the message is played.

[0013]

According to the present invention, the complicated key operation in the conventional schedule function can be eliminated and the operability of the schedule book function can be improved.
