Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a portable radio telephone having a function of setting an outgoing call possible time and / or an upper limit of a charge.

[0002]

[Prior art]

 Current portable radio handsets, such as PHS, are mainly targeted at young teens to middle-aged and senior workers. In the future, as the market for mobile radiotelephones expands, it is expected that a wide range of users, including children and the elderly, will become users.

[0005] However, in the case of the above-mentioned users, there is a case where a person in a guardian's position contracts and lends the contract. In that case, the monthly fee will be paid by the parent, and the actual user, such as a child or the elderly, will be less aware of the charge burden, the monthly call fee will be higher, and the parent will have to pay more. You will not be able to grasp it. Therefore, it is conceivable to set upper limits for monthly call time and charges in order to prevent such a situation.

[0004] However, currently implemented methods include (i) dialing restriction (only dialing abbreviated dialing is possible and restricting international dialing), and (ii) dialing restriction (change of abbreviated dialing contents). Regulations), (iii) Restrictions on incoming calls (only total incoming calls are restricted). On the network side, for example, there is a service with a call fee of 10,000 yen / month.

[0005]

[Problems to be solved by the invention]

 However, in the conventional method described above, the call destination is limited, and the upper limit of the call charge is fixed at $ 10,000 / month depending on the service on the network side, and lacks flexibility, and is not sufficiently practical. Missing.

[0006] Therefore, an object of the present invention is to provide a portable radio telephone with a function for setting an available call time and / or an upper limit of a charge so that the call charge can be regulated with sufficient practicality.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, the portable radio telephone according to the present invention has an outgoing call time setting means for setting an upper limit of an outgoing call available time and / or a charge, and when the outgoing call time and / or the charge reaches the above upper limit, The gist of the invention is to provide an outgoing call stopping means for stopping the outgoing call.

[0008] In the present invention, at least one specific key may be provided, and only the transmission by the specific key may be performed.

[0009] Alternatively, means for displaying the total time of the outgoing call at the end of the outgoing call or when the power is turned on is provided, or an alarm is generated to generate an alarm when the outgoing call available time and / or the charge reaches a predetermined value smaller than the upper limit. Means may be provided.

[0010] Furthermore, a reset means for resetting the upper limit by inputting a password or an initializing means for initializing the total number of outgoing calls on a predetermined date every month may be provided.

[0011]

[Embodiment of the invention]

 FIG. 1 shows an embodiment of the portable radio telephone of the present invention. In the figure, 1 is a control circuit (CPU), 2 is a ROM, 3 is a RAM, 4 is a display, 5 is a keypad, 6 is a speaker, 7 is a microphone, 8 is a modulation circuit, 9 is a demodulation circuit, and 10 is a power supply. A switch, 11 is a transmitting / receiving antenna, and 12 is an alarm signal generator.

As shown in FIG. 2, the ROM 2 includes a basic software area 2a, a telephone memory area 2b, an operation control software area 2c relating to the outgoing communication time and the call charge, and a directory file area 2d (for the telephone and the An operation instruction area for operation control) is provided. A telephone number, frequency information, a password, and the like necessary for connection are written in a telephone memory area 2b of the ROM 2, and necessary information is called from this area at the time of outgoing / incoming calls to perform a function as a telephone. There is no difference in this point from the conventional mobile radiotelephone.

Next, the portable wireless telephone of the present invention performs the following functions based on the information in the operation control software area 2c. That is, first, means for setting the upper limit of the outgoing call possible time by operating the function keys and numeric keys of the keypad 5, and when the outgoing call time reaches the upper limit under the control of the control circuit 1, the outgoing call is stopped. A means is provided to make it impossible. However, while it is possible to make a call by inputting at least one specific key in the keypad 5 such as an auto dial, it is not possible to rewrite the auto dial during the setting.

At the end of the outgoing call and when the power is turned on, the remaining time is displayed on the screen of the display 4 in order to confirm the remaining available time of the outgoing call. In addition, when the remaining time is less than 5 minutes, for example, the alarm signal generator 12 generates an alarm signal according to a command from the control circuit 1 and sounds an alarm from the speaker 6.

The upper limit can be set as appropriate, such as every 10 minutes from 10 minutes to 1000 minutes. In addition, the cumulative outgoing call time can be set to be reset to the specified date every month, and when that date comes, the cumulative total will be automatically reset and a new total will be started. .

Further, it is preferable that the upper limit of the outgoing call possible time is set so that it cannot be reset unless a password is input so that the upper limit of the outgoing call possible time cannot be changed without permission. It is desirable that the upper limit of the outgoing call possible time and the total sum of the outgoing call time are displayed on the screen of the display 4 so that they can be confirmed.

Further, in the above-described example, the upper limit of the outgoing call possible time is set. However, not the time but the charge or the upper limit of the time and the charge may be set. This charge can be easily set using the call charge information provided by the network side (telephone company).

FIG. 3 is a flowchart showing an example of the operation of the device of the present invention of FIG. In this figure, in step S1, for example, the function key F55 of the keypad 5 is pressed to set the outgoing call available time setting state. In this state, if the ten key T1 is pressed, the process proceeds to step S3, and if the ten key T3 is pressed, the step is performed. The personal identification number is displayed in S2. When the PIN is entered in step S3, the upper limit of the outgoing call possible time previously set is reset. In step S4, the upper limit of the outgoing call available time is set. Displays the cumulative time. Next, when the memory key is pressed, the upper limit time set in the RAM 3 in step S5 is stored. When the memory key is pressed again, it is determined in step S6 whether or not the accumulated time is cleared. If yes, if the numeric keypad T1 is pressed, the keypad is cleared and the process returns to S5. If no, the numeric keypad T3 is pressed. Return to S4 without clearing.

FIG. 4 is a flowchart showing an operation example of the upper limit time and the cumulative time. For example, when the function key F56 in the keypad 5 is pressed, the cumulative time is displayed on the display 4 in step S7. At the end of the outgoing call and when the power switch 10 is turned on, the remaining talkable time is displayed on the display 4 in step S8, and when an appropriate clear key is pressed, the display is cleared and the screen returns to the standby screen in step S9.

[Effect of the invention]

 As described above, according to the present invention, it is possible to flexibly set the upper limit of the outgoing call possible time and / or the charge, and even after reaching the upper limit, it is possible to make a call to the emergency contact using a specific key. . In addition, if the remaining time and / or the charge of the outgoing call can be displayed at the end of the outgoing call and when the power is turned on, the practical effect, such as allowing the user to strongly recognize the usable range of the mobile radio telephone, is not achieved. It is enormous.
