Description

[Detailed Description of the Invention] The present invention makes it possible to restrict outgoing calls by region for outgoing calls from a mobile phone, and also allows the registration and deletion of outgoing outgoing restriction information to be arbitrarily and easily performed from the mobile phone. This relates to a mobile phone calling regulation system.

Mobile telephones such as car telephones can be used to make calls anywhere in the country, just like landline telephones. Generally, subscriber telephones can be freely used by parties other than the subscriber, but the subscriber is always responsible for paying the telephone charges.
Subscribers are required to manage their services appropriately to avoid unexpected damage caused by unauthorized use by related parties.
However, compared to general fixed-line telephones, mobile telephones have a problem in that it is difficult for subscribers to manage their outgoing calls. For example, even if an employer intends to permit an employee (car driver) to make calls only to a designated area (for example, local calls) and restrict calls to other areas, under the conventional system, this is not possible. It cannot be expected that such transmission regulations will be guaranteed by physical strictness.

The present invention has been made in view of the above-mentioned drawbacks of the conventional system, and its first object is to provide a call restriction system that allows calls from mobile telephones to be restricted by region.

A second object of the present invention is to provide a call restriction system that allows only a specific person to freely and easily register and delete the call restriction service using the mobile telephone.

The details of the present invention will be explained below with reference to the drawings.

Reference numeral 8 designates a control line for interface between the outgoing call restriction reception device 7 and the control circuit 5, 9 a talk announcement generator for informing that incoming calls are restricted, 10 a general fixed telephone network, and 11 a general fixed telephone set. .

FIG. 2 is an explanatory diagram of a dialing sequence from a car telephone for receiving call restriction service. (a) is the call restriction service registration procedure, and (b) is the same cancellation procedure. 12 is the call restriction service number, 1
3 is a warning sound that notifies that preparations are made to receive instructions for registration/cancellation of the call restriction service from the mobile telephone exchange, 14 is a call restriction service registration/cancellation display section, and 15 is a call restriction for cancellation by another person. /
The password number 16 is used to prevent registration, the number 16 is the local area number for which calls are permitted, and the number 17 is the acceptance completion tone from the mobile phone exchange.

The operation of one embodiment of the present invention illustrated in FIGS. 1 and 2 will be described below.

Registration and Deregistration Operations The mobile phone subscriber first dials the call restriction service number 12 in order to receive the call restriction service. The car telephone exchange 3 that received the call restriction service number 12 connects the calling car phone 1 and the call restriction reception device 7 via the switch network 4 and the wireless base station 2, and the call restriction reception device 7 registers/receives the call restriction reception device 7.
A forecast sound 13 is sent to notify the completion of preparation for cancellation acceptance. After confirming the forecast tone 13, the car phone subscriber dials according to the procedure (a) if the call restriction is registered, or according to the step (b) if the call restriction is canceled.

The control circuit 5 of the mobile telephone exchange 3 monitors the call control reception device 7 via the interface line 8, and when dialed numbers are sent from the mobile device, the dialed numbers are transferred to the storage device 6. Make me remember. When it is determined that all the digits have been received, the control circuit 5 compares the password 15 sent from the vehicle phone with the PIN pre-stored in the storage location of the storage device 6 that corresponds to the vehicle phone, and determines whether the numbers are different. In this case, the call regulation acceptance device 7 sends an acceptance rejection tone to the car telephone.

If the password is verified, it is determined whether it is registration or cancellation based on the registration/cancellation display section 14 of the received dial digits. In the case of registration, the control circuit 5 stores information indicating that incoming calls are being restricted and the call-permitted destination area number 16 dialed from the car phone in a memory location corresponding to the car phone in the storage device 6. In the case of cancellation, the control circuit 5
The information indicating that outgoing calls are restricted and the calling area number 16 stored in the storage location corresponding to the car phone are cleared.

When the incoming call restriction service registration or cancellation operation is completed according to the above-described procedure, the outgoing call restriction reception device 7 sends out an acceptance completion sound 17. For car phone subscribers,
When the user turns on the phone after hearing the acceptance completion tone 17 from the mobile telephone exchange 3, the registration/cancellation of the call restriction service is completed.

Call restriction operation When the car telephone exchange 3 detects a call from the car phone 1 and completes receiving the dialed digits from the car phone 1, it stores a message indicating that the call is being restricted in a memory location corresponding to the car phone in the storage device 6. Check whether the information is remembered. If stored, the dialed area number is compared with the separately stored calling permission destination area number. If call restriction is not registered, or even if it is registered, if the dialed number is the same as the dialed number, a normal connection is made.

If call regulation has been registered and the dialed area number and the call-permitted local area number are different, the talkie announcement generator 9 notifies the car phone that call restrictions are being implemented.

In the above embodiment, the call restriction service number 12 and the registration/cancellation display section 14 are provided separately, but the service number 12 can be substituted or used in combination with the display section 14, or both can be integrated. It can also be configured. This also applies to the password number 15. Furthermore, the order in which the display unit 14, password 15, and call permission destination station number 16 are sent can be changed as appropriate.

As explained above, according to the present invention, by registering call permission destination information in a mobile telephone switching center such as the car telephone switching center 3, calls to destinations other than the call permission destinations will not be made unless this registration is canceled. Due to the regulation, there is no risk of accidental damage to the owner of the mobile phone. In addition, since the predetermined password information is compared with the password information sent from the mobile phone, and only if there is a match, the calling permission destination information is registered or deleted.
Only a specific person, such as the owner of a mobile phone, will be able to register or cancel the registration.
