The storage medium is assigned to a control program of a control unit 100, which will be described later, or is previously assigned to itself by the system. In addition to various control data such as ID data and various setting information, as a telephone directory data, a memory dial storage area 60a which stores dial data and data for identifying a ringing melody to be described later in association with a destination name, A melody data storage area 60b is provided for storing a plurality of incoming melody data, such as set incoming melody data and incoming melody data input by the user.

In response to an instruction from the control unit 100, the incoming call notification control unit 70 reproduces and outputs an incoming melody from the sounder 80, and controls driving of a backlight 90 described later. The backlight 90 is provided in the vicinity of the display unit 30 and the operation unit 50, and controls the incoming call notification control unit 70 or the control unit 1
00, the display unit 30 and the operation unit 5
0 is illuminated.

FIG. 2 shows the configuration of the incoming call notification control unit 70 and the backlight 90 in more detail. Incoming call notification controller 7
0 is a control circuit 71, a driving circuit 72, a frequency decoding circuit 73, a frequency classification circuit 74, and an AND circuit 75
1 to 75n. The backlight 90 includes light emitting elements 91 to 9n such as light emitting diodes.

The control circuit 71 sequentially receives the incoming melody data stored in the melody data storage area 60b read out by the control unit 100, and according to the instruction of the control unit 100, drives the drive circuit 72, The signal is input to one or both of the circuits 73.

The driving circuit 72 drives the sounder 80 based on the incoming melody data sequentially input through the control circuit 71 to output the incoming melody in a loud voice. The frequency decoding circuit 73 analyzes the scale (frequency) of the incoming melody data sequentially input through the control circuit 71 and notifies the frequency classification circuit 74 of the analysis result.

The frequency classification circuit 74 inputs "H" level signals to the AND circuits 751 to 75n corresponding to each musical scale based on the musical scale analysis result notified from the frequency decoding circuit 73.

The AND circuits 751 to 75n are respectively
The output from the control circuit 71 to the drive circuit 72 and the output from the frequency classification circuit 74 are input, ANDed between them, and inverted and output. Therefore, as shown in FIG. 3, only when both are at the “H” level, an “L” level signal is input to the cathode terminals of the corresponding light emitting elements 91 to 9 n.

Each of the light-emitting elements 91 to 9n has a voltage VDD higher than the above-mentioned "L" level applied to its anode end, and emits light when the above-mentioned "L" -level signal is input to its cathode end.

The control unit 100 includes, for example, a microcomputer as a main control unit, and controls each unit of the mobile radio terminal device in general. In addition to a control function for performing normal voice communication, the control unit 100 directly Or the incoming call notification control unit 7

Next, the operation of the mobile radio terminal having the above configuration at the time of an incoming call will be described. The control of the operation described below is performed by the incoming call notification control unit 70 and the control unit 10.
Done by 0. FIG. 4 shows a flowchart of the operation.

First, in step 4a, the occurrence of an incoming call is monitored, and when an incoming call occurs, the process proceeds to step 4b. In step 4b, it is determined whether or not the incoming signal includes information on the telephone number of the caller. Here, when the information of the telephone number of the caller is included, the process proceeds to step 4c.

On the other hand, if the information of the telephone number of the caller is not included, the process proceeds to step 4d, in which a preset melody is reproduced or a ring tone is emitted, and the backlight 90 is fully lit. Of the incoming call notification operation, and waits for a response.

In step 4c, it is determined whether or not the telephone number of the caller notified through the incoming signal is recorded in the memory dial storage area 60a of the storage unit 60. Here, if it is recorded, the process proceeds to step 4f.

On the other hand, if the notified telephone number is not recorded in the memory dial storage area 60a, the process proceeds to step 4e, where the notified telephone number is displayed on the display unit 3.
0 is displayed, and the process proceeds to step 4d.

In step 4f, the name information corresponding to the notified telephone number is stored in the memory dial storage area 60.
a and read out on the display unit 30, and read out the
Move to

At step 4g, the identification information of the incoming melody corresponding to the notified telephone number is read from the memory dial storage area 60a, and the data of the incoming melody corresponding to the read identification information is read from the melody data storage area 60b. Then, the read incoming melody data is input to the incoming call notification control unit 70.

Thus, in the incoming call notification control section 70, the control circuit 71 inputs the incoming melody data input from the control section 100 to one end of the AND circuits 751 to 75n, the frequency decoding circuit 73 and the driving circuit 72. Drives the sounder 80 to output an incoming melody.

At this time, the frequency decoding circuit 73 analyzes the scale (frequency) of the incoming melody data sequentially input through the control circuit 71 and notifies the frequency classification circuit 74 of the analysis result.

Then, based on the scale analysis result notified from the frequency decoding circuit 73, the frequency classification circuit 74 inputs the "H" level signal to the AND circuits 751 to 75n corresponding to each scale.

Thus, AND circuits 751 to 75n
Respectively, when the output from the control circuit 71 to the drive circuit 72 and the output from the frequency classification circuit 74 are both at the “H” level, the “L” level signal is output to the corresponding light emitting element 91 to
Input to the cathode terminal of 9n. That is, the light emitting elements 91 to 9n corresponding to the scale being output are turned on.

In step 4h, the operation of the operation unit 50 is monitored by the user. If the operation is not performed, the process proceeds to step 4g. On the other hand, if the operation on the operation unit 50 is detected, After terminating the process, a call process is executed.

As described above, in the mobile radio terminal having the above-described configuration, the backlight 9 has a pattern corresponding to the incoming melody corresponding to the telephone number notified by the caller at the time of an incoming call.
The lighting control of the light emitting elements 91 to 9n of 0 is performed.

That is, since the backlight 90 is driven and controlled by a lighting pattern corresponding to the caller, even in a situation where the user cannot recognize the ringtone, the lighting pattern of the backlight 90 makes it possible to determine the calling party. Can be identified.

The present invention is not limited to the above embodiment. It goes without saying that various modifications can be made without departing from the spirit of the present invention.

[0040]

As described above, according to the present invention, the incoming call is notified by controlling the driving of the light emitting means of the illuminating means with a light emitting pattern corresponding to the telephone number of the caller notified through the incoming signal. I have to.

Therefore, according to the present invention, at the time of an incoming call, a plurality of light emitting means are turned on in a pattern corresponding to the caller, so that the lighting pattern makes it impossible for the user to recognize the ring tone. Even so, it is possible to provide a mobile wireless terminal device capable of visually identifying a caller.
