Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone device, and more particularly to a portable telephone device of a PHS type.
The present invention relates to switching of display between a public communication mode and a private communication mode of a simple portable telephone.

[0002]

2. Description of the Related Art A handset (PH) of a simple PHS portable telephone device
S-type mobile phones) are used in public places such as outdoors and connected to a public base station (hereinafter referred to as public mode), and digital cordless telephones used as private base stations used in homes and the like. Has a self-service communication mode (hereinafter referred to as a home mode) which is used by being connected to the parent device.

The conventional PHS portable telephone has a problem that it is necessary to switch between the public mode when going out and the home mode when at home.

In order to avoid this, there is a method of automatically switching between the public mode and the home mode using a mode called an auto mode or a dual mode. In the auto mode, the radio wave from the base unit is monitored, and when the radio wave from the base unit is within the range, the mode is automatically switched to the home mode, and when out of the range, the mode is automatically switched to the public mode.

In the dual mode, both the radio wave from the base unit and the radio wave from the public base station are monitored, and as long as the radio wave has arrived, transmission and reception can be performed from either of them. Give priority to the higher priority, usually the home mode, that is, the call from the base unit,
Incoming calls are received from both the home mode and the public mode. If the incoming calls come from the same source, the incoming call from the base unit has priority.

However, even when such a method is used, there are differences in the types of functions that can be used when connected to the base unit and when connected to a public base station, and cannot be used at this time. It is desirable that the function buttons are not displayed to the user. For example, a function button not used in the public mode may be used in the home mode. For example, there is an "extension" button that calls another PHS simplified mobile phone or parent device in the home, and a "catch" button that responds to an incoming call from an outside line when there is a call from an outside line during an extension call. This is the case.

However, since the size and weight of a simple PHS mobile phone are limited, the number of buttons is also limited. Therefore, one button has two or more functions, and this button is pressed depending on the state of the device. It is common to switch the operation when the operation is performed. For this reason, a method is employed in which one button indicates two functions in small characters, or another function is displayed on the side of the button.

FIGS. 7 and 8 show such a conventional PHS.
It is an example of a display of a button function in a simple type mobile phone. 7 and 8 show examples of the display when the hold button is shared with the extension call button and the registration button is shared with the catch button. In FIG. 7, "extension" and "catch" are displayed outside the fields of the hold button and the registration button. FIG. 8 shows a case where “extension” and “catch” are displayed together with the display of the hold button and the registration button. In any of these methods, there is a problem that the display is small and difficult to see, and the display on the operation panel screen is congested.

As described above, in the conventional method, the buttons are commonly used, and the display of the functions not used is also displayed depending on the connection destination. Therefore, there is a problem that the display is complicated and difficult to understand.

[0010]

As described above, in the conventional simple type portable telephone, the functions that can be specified depending on whether or not the portable telephone is within the home mode are different, and the function buttons are commonly used for a plurality of functions. Since functions that cannot be used are displayed in the same place, there is a problem that the display is inevitably complicated and the display characters are small and difficult to understand.

An object of the present invention is to solve the above-mentioned problem, and to provide a simplified portable telephone in which only functions that can be used by a relatively simple method are displayed in a large size and a panel surface can be clearly viewed.

[0012]

To achieve the above object, the present invention provides a transmitting means, a receiving means, a displaying means,
A public communication mode comprising dial input means and a function selecting means and wirelessly connected to an outdoor public base station for communication, and a private communication mode for wireless communication and communication to an indoor self-operating base station. In the portable telephone having, when the self-service communication mode is selected, the display means displays a display of a function used only in the self-service communication mode by attaching the function to the corresponding function selection means. I do.
