Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a PDC according to an embodiment of the present invention.
FIG. 2 is a block diagram illustrating a configuration of a PHS-integrated mobile terminal. In FIG. 1, the PDC / PHS integrated mobile terminal is
An antenna 10 switched by a switch 20 and a PHS
A radio unit 30, a PDC radio unit 40, a control unit 50 for controlling the radio units, a key operation unit 60 connected to the control unit 50,
It comprises a liquid crystal display unit 70, a liquid crystal backlight control unit 80, and an LED control unit 90.

The control unit 50 includes a PHS control unit 51, a PD
The PHS control unit 51 includes a C control unit 53 and a memory unit 54.
The DC control unit 53 is connected to the CPU unit 55 via the mode switching means 52, and the CPU unit 55 further includes a key operation unit 60, a liquid crystal display unit.
The control unit 70 is connected to the liquid crystal backlight control unit 80 and the LED control unit 90 to perform control, and is connected to the memory unit 54 to store and retrieve necessary control data. The PHS control unit 51 and the PDC control unit 53 are connected to the PHS radio unit 30 and P
The DC radio unit 40 is controlled.

In the PHS mode, the PHS control unit
51 checks the reception electric field level input from the PHS radio unit 30, and when the reception electric field level falls below the reception electric field limit value, the mode switching unit 52 switches the operation to the PDC control unit 53 and the operation to the radio unit 40 to set the PDC mode. be able to. At this time, the liquid crystal display unit 70 displays that the mode is the PDC mode.

In the PDC mode, the PDC control unit
53 checks the reception electric field level input from the PDC radio unit 40, and if the reception electric field level falls below the reception electric field limit value, the mode is switched to the operation of the PHS control unit 51 and the radio unit 52 by the mode switching unit 52 to set the PHS mode. Can be. At this time,
The liquid crystal display unit 70 displays the PHS mode.

Next, the operation of the PDC / PHS integrated mobile terminal according to the embodiment of the present invention will be described with reference to the screen display of FIG. In FIG. 2, the communication pictogram shown on the first screen indicates that the standby mode is PHS and the office station 1 (OS1) is set. When the user presses the dial key "0" to make a call, the mobile phone is set to the priority setting of the outgoing call mode that has already been set. As shown in the above, "Keitai" is displayed on the upper right of the screen, and "0" input by dial is displayed on the screen.

Next, pressing the dial key indicates "45321123".
If you continue with "4", the screen shown in FIG. 2 will be displayed.
In this state, when the key for switching the transmission mode provided by the present invention, that is, the “SELECT” key operation is performed, the transmission mode of “PHS” is displayed at the upper left of the screen as shown in FIG. The selection is displayed, and then, when the "call" key is pressed, as shown in FIG. 2, a communication pictogram of ringing during connection is displayed at the lower left of the screen.
Here, when the other party answers, the elapsed time of the call is displayed at the lower right of the screen as shown in FIG. 2 to confirm that the call is in progress.

When the "end" key is pressed or a disconnection notification is received from the other party at the end of the call, the call is ended as shown in FIG. 2 and the screen returns to the first screen, that is, the standby screen.

On the other hand, if the "call" key is depressed without operating the "SELECT" key in FIG. 2, the call is transmitted by the mobile phone according to the priority setting in the original transmission mode, as shown in FIG. Then, a display in which the communication pictogram of the ringing sound during connection is turned on is displayed.

Then, as shown in FIG. 2, when the notification of the communication area of "Keitai" is received, a display indicating the notification is made at the upper right of the screen. Then, the process proceeds to a call, and the elapsed time of the call is displayed at the lower right of the screen as shown in FIG.

When the "end" key is pressed or the disconnection notification is received from the other party at the end of the call, the call is ended as shown in FIG. 2, and the screen returns to the first screen, that is, the standby screen.

It should be noted that how to display the screen at the time of standby can be performed at the time of initial setting. In the above description, the example in which the standby mode is PHS has been described. Even in the standby mode, the above description of the operation may be made by reading the PHS instead of the PDC, and it is possible to understand the operation.

As described above, in the embodiment of the present invention, the set transmission mode can be easily changed only by operating the key for switching the transmission mode, that is, the "SELECT" key provided by the present invention. Thus, an easy-to-use PDC / PHS integrated mobile terminal can be provided.

In the above description, the user can determine the transmission mode set without changing the color of the liquid crystal backlight or the LE without reading the communication pictogram.
It is convenient to be able to identify by the color of D. For example, if the color of the liquid crystal backlight or the color of the LED is "green", the mode is "PHS" mode, and if the color is "red", the mode is "mobile" mode. In such an operation, the CPU unit 55 in FIG. 1 controls the liquid crystal backlight control unit 80 and the LED control unit 90, and the liquid crystal backlight control unit 80 and the LED control unit 90 determine the color of the liquid crystal backlight and the color of the LED. Can be realized by controlling

It is needless to say that the mode discrimination based on the color can be applied to the "incoming mode" by using only the "outgoing mode" as described above. That is, in the display of the “incoming mode”, for example, if the color of the liquid crystal backlight or the color of the LED is “green”, “PHS”
Mode, or if it is "red", then it is "mobile" mode.

Further, the determination of the mode is not limited to the above-mentioned "color", but the CPU 55 of FIG. 1 may control the liquid crystal display 70 to display "character" on the display. LED is controlled by turning on / off the LED
The mode may be displayed by turning off the light.

[0031]

As is apparent from the above description, the present invention provides a key operation section, a liquid crystal display section, a PHS radio section and a PHS
PD including a DC radio unit and a control unit that controls them
In the C / PHS integrated mobile terminal, transmission mode display means for displaying a set transmission mode on the liquid crystal display unit, and when transmitting in a transmission mode different from the displayed transmission mode, switching between transmission modes. A transmission mode switching means for performing a key operation, and a telephone connection means for performing a telephone connection based on a key operation for switching a transmission mode and a subsequent dial key operation. This has an effect that the transmission mode of PDC and PHS can be switched with one touch.
