The EY 12 is connected and has a function of controlling a corresponding sounder, microphone, speaker, LCD, and KEY.

Next, the processing of the present invention will be described. FIG. 2 shows a flowchart of the embodiment of the present invention. This flowchart shows how the transmission mode is determined in the processing from when the user performs the transmission operation to when the mobile terminal device performs the transmission operation. The mobile terminal device is registered in the public mode and the office mode, and is set in the simultaneous standby mode. When the simultaneous standby mode is not set, or when only one of the public mode and the office mode is registered, the processing shown in FIG. 2 is not performed.

First, when the user performs a call operation (step 101), the portable terminal device determines whether the telephone number of the call destination is a telephone number of a public telephone network (step 102). Here, the public telephone network telephone number is a public telephone number generally used,
It also includes the telephone number of the portable terminal device (for example, PHS or the like). In the mobile terminal device, for example, when the first number of the telephone number of the call destination is “0”, the determination is made by processing of recognizing the telephone number as a telephone number of a public telephone network. Also, depending on the setting of the business establishment, the first number of the destination telephone number may be other than "0". To be able to set.

Next, if the destination telephone number is a telephone number of a public telephone network, an outside line transmission number is added to the telephone number (step 103), and a calling operation is performed in the office mode (step 105). At this time, the outside line calling number can be set in advance by the user or before the calling operation (step 1).
(Before the processing of step 03). If you do not need to add an outside line number in your business settings,
Step 103 can be omitted.

If the destination telephone number is not the telephone number of the public telephone network, the calling operation is performed in the office mode with the destination telephone number as the telephone number of the extension telephone (step 104).

Next, it is determined whether or not communication has been established as a result of performing a calling operation in a business office mode to a telephone in a public telephone network (step 106). If the communication is established, the communication mode is established in the office mode (step 107). If communication cannot be established due to congestion of the office network or the like, transmission is performed again in the public mode (step 10).
8). The telephone number when this calling operation is performed again is a number obtained by removing the external line calling number added (in step 103).

When an appropriate transmission mode is automatically selected by the above processing, the user can perform a transmission operation without being conscious of the transmission mode. When making a call to the public telephone network, communication costs are generally lower in the office mode than in the public mode. Therefore, when a call cannot be established by making a call in the operator mode as in the present embodiment, it is economical to make a call in the public mode.

Next, a first embodiment of the present invention will be described. FIG. 3 shows a flowchart of the first embodiment.
In the first embodiment, a step (step 202) for determining whether or not automatic transmission destination selection is selected (hereinafter, referred to as “ON”) is added to the embodiment. In the above-described embodiment, the transmission mode is always automatically selected. However, in the present embodiment, when the automatic transmission destination selection is ON, the above-described selection is performed. If the automatic transmission destination selection is not selected (hereinafter, referred to as "OFF"), the transmission operation is performed in the transmission mode specified when the transmission operation is performed (step 204). In the transmission mode, either the public mode or the office mode is specified as the transmission mode in the simultaneous standby mode.

The ON / OFF information for automatic selection of the destination is set by the user from the portable terminal device. In this embodiment, since the user can select whether or not to select the transmission mode according to the user's will. This is convenient because it is possible to set the time other than the above to the public mode and separate accounting (communication charges) between public and private use.

Next, a second embodiment of the present invention will be described. FIG. 4 shows a flowchart of the second embodiment.
In the second embodiment, steps 305, 310, 312, 313, and 315 are added to the first embodiment described above. These steps are performed before the call operation
If the outgoing call mode is out of the service area, the process is for canceling the outgoing call operation.

Referring to FIGS. 3 and 4, before adding an outside line calling number to a telephone number (step 205), it is determined whether the telephone number is within the business office mode (step 305). If it is within the business office mode, processing is performed in the same manner as in the above-described embodiment. If the business mode is out of the service area, it is determined whether the business mode is in the public mode (step 310). In the case of being within the public mode, the calling operation is performed in the public mode (step 31).
1) If it is out of the public mode area, the transmitting operation is stopped (step 312).

Before the transmission operation in the office mode (step 206), it is determined whether the office mode is within the service area (step 313). If the area is in the office mode, the transmitting operation is performed in the office mode (step 314). If the area is out of the office mode, the transmitting operation is stopped (step 315).

When the transmission mode is out of the service area as in the second embodiment, the transmission operation is not performed in the transmission mode, so that useless transmission operation can be prevented.

Next, a third embodiment will be described. FIG. 5 shows a flowchart of the third embodiment of the present invention.
In the third embodiment, when the user performs data transmission,
The transmission mode is selected with priority given to the data communication speed.

First, when a data transmission operation is performed (step 402), it is determined whether to give priority to the data communication speed (step 402). Whether to give priority to the data communication speed can be preset by the user by turning on / off the portable terminal device. When priority is given to the data communication speed (when ON), the CS waiting in the office mode is 64 kbps.
It is determined whether the communication is supported (step 403). If the communication is supported, the data transmission operation is performed as in the above-described embodiment (steps 404 to 409).
If the data communication speed is not prioritized (OFF), the process proceeds to the next process.

If the CS in the office mode does not support the 64 kbps communication, the CS waiting in the public mode
Is determined to support 64 kbps communication (step 411). If the CS in the public mode supports 64 kbps communication, the transmission operation is performed in the public mode with priority given to the data communication speed (step 412). Public mode CS
Does not correspond to 64 kbps communication, a data transmission operation is performed in the same manner as in the above-described embodiment (step 404).
Step 409). According to the third embodiment, when performing the data communication, the transmission operation with priority given to the data communication speed can be performed by performing the transmission operation preferentially in the mode of waiting at 64 kbps. For data communication,
Although the case of 64 kbps has been described, the present invention is not limited to this.

In the present invention, the office mode is generally selected first as the transmission mode because the communication cost is lower and the radio wave condition is more stable. If the communication mode is lower in the public mode because of the setting of a charge plan or the like, the public mode can be first selected as the transmission mode.

[0032]

According to the present invention, in the portable terminal device in the simultaneous standby mode in the public mode and the office mode,
Since the transmission mode is automatically selected, there is an effect that the user can perform an appropriate transmission operation without being conscious of the transmission mode. In addition, it is more economical to send a call in the office mode than in the public mode, because communication costs are generally lower.

In the present invention, the transmission mode selection is
Since the user can select F from the portable terminal device, there is an effect that convenience of use can be achieved.

Further, according to the present invention, when the selected transmission mode is out of the service area, the transmission operation in the transmission mode is stopped, so that there is an effect that useless transmission operation can be prevented.

Further, according to the present invention, when performing data communication, the transmission operation is preferentially performed from the mode waiting at 64 kbps, so that the transmission operation can be performed with priority given to the data communication speed.
