DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication system, a method for restricting incoming calls thereof, and a recording medium on which a control program is recorded, and more particularly to a system for restricting incoming calls of mobile telephones belonging to the mobile communication system.

[0002]

2. Description of the Related Art Conventionally, in a mobile communication system, communication is possible even if a mobile telephone is moving within its service area. However, communication by a mobile telephone may be performed while driving a car or in a public vehicle, and such communication is becoming a social problem.

[0003] For example, the use of a mobile telephone while driving a car distracts the driver from driving, resulting in an increase in traffic accidents. In addition, the use of a mobile phone in a public vehicle causes annoyance in the form of radio waves and sounds to others riding in the vehicle.

In order to solve these problems, in a conventional mobile communication system, a mobile telephone subscriber registers himself / herself as "moving" with the system before starting operation of a car. Means are considered in which even if there is an incoming call when "moving" is registered, the subscriber is not allowed to receive an incoming call other than an emergency call.

Further, public vehicles and the like are calling for non-use of mobile telephones in their vehicles, and the methods of turning off the power of the mobile telephones and the above-mentioned incoming call control method are used.
This method of restricting incoming calls is described in Japanese Patent Application Laid-Open No. 56-4244.
No. 2 discloses this.

On the other hand, in the conventional mobile communication system, a method is adopted in which the incoming call to the mobile telephone is regulated and controlled in conjunction with a device provided in the vehicle according to the operation and speed of the vehicle. This regulation control method is disclosed in Japanese Patent Application Laid-Open Nos. 60-84032 and 3-198540.

[0007]

In the above-described conventional method for controlling a mobile communication system, the restriction of incoming calls and the like is left to the judgment of the mobile telephone subscriber, so that the mobile telephone subscriber must be careful and careless. There is no end to traffic accidents caused by the use of a mobile phone while driving a car, and inconvenience to other passengers when using a mobile phone in a public vehicle.

[0008] Further, the method of restricting and controlling the incoming call to the mobile telephone in accordance with the operation and speed condition of the vehicle in conjunction with the device provided in the vehicle is not effective unless the mobile telephone is connected to the vehicle.

Therefore, an object of the present invention is to solve the above-mentioned problems, and to solve the problem by using a mobile phone in a traffic accident or a public vehicle while driving a car, even if the mobile phone is not connected to a car. It is an object of the present invention to provide a mobile communication system capable of preventing inconvenience to other passengers, a method for restricting incoming calls, and a recording medium recording a control program therefor.

[0010]

A mobile communication system according to the present invention comprises a mobile telephone exchange, a plurality of radio base stations and a plurality of mobile telephones,
Storage means for storing the location registration time and the registered location by the location registration from the mobile telephone for a certain period of time or more; location registration of the mobile telephone per unit time based on the content stored in the storage means The mobile telephone exchange includes a calculating means for calculating the number of times, and a restricting means for restricting an incoming call to the mobile telephone when a result of the calculation by the calculating means is equal to or more than a predetermined value.

A method for restricting incoming call of a mobile communication system according to the present invention is a method for restricting incoming call of a mobile communication system comprising a mobile telephone exchange, a plurality of radio base stations, and a plurality of mobile telephones. Storing the position registration time and the registered position by a registration for a certain period of time or more; calculating the number of position registrations per unit time of the mobile telephone based on the stored contents; Restricting an incoming call to the mobile telephone when is greater than or equal to a predetermined value set in advance in the mobile telephone exchange.

The recording medium storing the incoming call restriction control program for the mobile communication system according to the present invention records the incoming call restriction control program for a mobile communication system comprising a mobile telephone exchange, a plurality of radio base stations, and a plurality of mobile telephones. In a recording medium, the incoming call restriction control program causes the mobile telephone exchange to store a time of the position registration and a registered position by a position registration from the mobile phone for a fixed time or more, and store the stored contents. Based on this, the number of location registrations per unit time of the mobile telephone is calculated, and when the calculation result is equal to or greater than a predetermined value, an incoming call to the mobile telephone is restricted.

That is, the mobile communication system according to the present invention comprises:
A function of storing the time and position at the time of position registration several times in a mobile telephone exchange using a position registration request function from a mobile telephone possessed in a conventional mobile communication system, and a predetermined time set in the mobile telephone exchange. And a function for calculating the number of location registrations within the server.

By using these functions, if the number of location registrations within a certain period of time exceeds a number set in advance as a reference for restricting incoming calls while moving, the mobile telephone exchange falls under the incoming call restrictions while moving. Then, the incoming call to the mobile telephone subscriber is restricted, and a message of the incoming call restriction during moving is automatically sent to the caller to connect to an answering service or the like.

If the number of location registrations of the mobile telephone falls below a predetermined number as a reference for restricting incoming calls while moving within a predetermined time, the mobile telephone exchange automatically switches to the mobile telephone attendant. Release the incoming call restriction for, and make a normal connection.

On the other hand, when a mobile telephone subscriber rides on a moving car as a driver other than the driver, the mobile telephone subscriber is informed of the mobile communication system that he or she is not driving the car before moving. Alternatively, the automatic registration restriction by the mobile communication system is avoided by performing the registration method set in advance while moving.

The registration for avoiding this problem is performed when the number of location registrations monitored by the mobile telephone exchange within a certain time period becomes equal to or less than a predetermined number as a reference for restricting incoming calls during movement. If it is determined that it is no longer inside, it is automatically released.

In the calculation of the number of location registrations, the radio base station area may overlap, for example, depending on the radio wave condition.
Since a so-called location registration flutter occurs and location registration may be repeated in a short time, location registration of the same location as the previously stored location (wireless base station area) is performed within a preset short time. Not considered in calculations.

As a result, the moving speed can be estimated based on the position, the time, and the number of times of the position registration, and depending on the estimated speed, other than when the person is stopped or walking, that is, in a car or a public vehicle. When it is determined that the mobile phone is moving, the mobile communication system can automatically regulate the incoming call to the mobile phone subscriber regardless of carelessness or omission of the mobile phone subscriber.

Thus, incoming calls to the mobile telephone subscriber while driving a car or traveling on a public vehicle or the like are regulated. It is possible to prevent inconvenience to other passengers from using the mobile telephone while traveling.
