Abstract

PROBLEM TO BE SOLVED: To decide a detailed call charge even when a rate plan is set to vary the call rate. SOLUTION: When a call is started in call mode, the current time is shown and the duration of the call is repetitively counted until the call is over (S10). When the call is over, the charging rates are selected (S12, S13, S14) according to the current time that is stored when the call is started (S11). When an charging rate is selected, this charging rate is multiplied by the duration of the call for calculating the call charge (S16).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone capable of confirming an accurate telephone charge even with a telephone charge plan that varies depending on a time zone.

[0002]

2. Description of the Related Art A conventional portable telephone is disclosed in
No. 1-177725 describes that time-based charge information is acquired from a network at the start of a call, and a call charge is calculated based on the charge information. Here, the table shown in FIG. 1 discloses the number of seconds during which a call can be made for 10 yen per time slot. When a call is started based on this table, the date / time information of the mobile phone, the time zone The charge addition seconds are obtained from the information of the separate charge addition information storage unit, and the notification timing (seconds) is calculated from “(charge addition seconds) − (notification time number of notification timing information storage unit)”, and at each interval. To notify the charge addition by sound or vibration.

[0003]

As described above, even in a conventional portable telephone, the charge calculation is automatically performed based on the time-based charge information transmitted from the network. However, recently, the rate plans offered by each mobile phone company have various plans such as increasing the standard fee payment at the time of contract and lowering the call fee, or reducing the standard fee payment and relatively increasing the call fee. Due to the ease of the plan, information transmitted from the network is no longer covered as before.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems. In a portable telephone used in a communication system having different call charges depending on a call time zone, a standard telephone call is provided for each call time zone. By registering a charging rate in proportion to a charge in a memory, a mobile phone is provided in which a call charge is obtained by multiplying a charging time used in each call time zone by a charging rate.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a mobile phone according to the present invention, FIG. 2 is a diagram illustrating a storage device used in the mobile phone according to the present invention in detail, and FIG. 3 is a charging rate storage used in the mobile phone according to the present invention. FIG. 4 is a flowchart for setting a charging rate in an area, and FIG. 4 is a flowchart for explaining the operation of the mobile phone of the present invention.

In FIG. 1, an antenna 17 for transmitting and receiving voice or data from a not-shown telephone is provided on a portable telephone 10, and a radio device 12 for modulating and demodulating voice or data received by the antenna 17 is provided. Is provided. A keypad 15 for inputting data to the telephone 10 is provided, and data input from the keypad 15 is stored in the storage device 16 and displayed on the display unit 13. Further, a CPU 11 that controls a series of these processes is provided.

FIG. 2 explains the contents stored in the storage device 16 shown in FIG. 1. The call start time storage area 21 is an area for storing the current time at the start of the call. The charging information storage area 22 is an area for storing charging information received from a network (not shown).
This area stores the unit talk time for a standard rate plan. The charge rate storage areas 1 to n store a charge rate 26 for a standard charge plan, and a start time and an end time indicating an effective time for the charge rate 26.

Referring to FIG. 3, a method for setting the charging rate described with reference to FIG. 2 will be described. When a function key of the keypad 15 shown in FIG. 1 is pressed, a message for setting a call charge is displayed (S1). Here, if 0 is selected, the call charge processing is stopped. When 1 is selected, a message for setting a call charge is displayed in the charging rate storage areas 1 to 3 (S2). When 1 is selected, a message for setting a charging rate is displayed in the charging rate storage area 1 (S3). Here, when 1.5 is input, 1.5 times is displayed on the display unit 13 (S4). Further, the call start time 7:00 and the end time 1 satisfying this condition are satisfied.
When 7:00 is input, the start time area 27 shown in FIG.
And the input time in the end time area 28 are stored.

The operation will be described with reference to FIGS. When a call is made from the mobile phone 10, the current time is acquired at the start of the call, and a call charge of a standard rate plan is received from the network at the start of the call. When a call is started, the call time is counted every second on the assumption that such information has already been acquired (S1).
0). This count is repeated until the end key is pressed or the other party ends the call (S10).

When a call termination event occurs, the billing rate storage shown in FIG. 2 in which the billing information is stored according to the current time (S11) stored at the time of the call start and the set range of each billing rate. The charging rates stored in the areas 1 to n are selected (S12, S13, S
14). If the current time does not fall within the set time range, the charging rate transmitted from the network is used without using the charging rate set by the user (S1).
5).

When the billing rate is selected as described above, the billing rate is multiplied by the talk time to calculate a talk charge (S1).
6).

[0012]

As described above, according to the present invention, since the charging rate proportional to the reference telephone charge is registered in the memory for each communication time zone, the communication time and the charging rate used in this communication time zone are registered. By multiplying by, a detailed call charge can be calculated.
