Abstract

PROBLEM TO BE SOLVED: To provide a cost reduction system for a user making a group contract of a plurality of mobile phones. SOLUTION: The mobile phone service system is built up where one telephone number line is contracted by a group such as a family, a branch number or the like is provided to each terminal, each terminal is distinguished from each other and each terminal can make transmission reception. A plurality of terminals have one telephone number, the user makes a one-line contract and the user can reduce the base charge to be paid for.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable telephone service system including a simplified portable telephone.

[0002]

2. Description of the Related Art In a conventional mobile phone service including a simplified mobile phone, for example, when four family members own a mobile phone, it is necessary to obtain a telephone number individually, for example, there is a family discount. Even so, they had to pay each basic fee, which caused considerable disadvantages for users.

[0003]

In order to eliminate the disadvantages caused by the above users, one of the methods used in ISDN or the like has been proposed.
By assigning branch numbers to a plurality of terminals with one telephone number and managing them, it is possible to manage telephone numbers with registered branch numbers without having to make contracts for multiple lines, and the basic fee is also one basic contract This can reduce the burden on the user.

In this case, since one telephone number contract is made, for example, four family members cannot simultaneously make outgoing calls, and only one person can talk to the outside. However, in a call between family members, a call can be made by adding a branch number and dialing.

[0005]

In order to achieve the above object, a portable telephone capable of registering and recognizing a branch number, a base station capable of connecting to a radio line with a contracted branch number, and a computer controlling the base station are provided. It consists of a system.

[0006]

FIG. 1 shows an example of a cellular phone system. An embodiment of the present invention is shown in FIGS.

As shown in FIG. 2, according to the conventional system, each person is given an individual telephone number and a basic fee is charged for each. In the present invention, it is an object of the present invention to reduce a basic charge by having a plurality of persons having the same telephone number (registering in a group). However, in order to recognize each person's terminal, a branch number is added in addition to the telephone number and managed.

[0008] The operation of the terminal, base station and computer system having this function will be described with reference to FIG.
As shown in, the base station and the computer system receiving the call from the terminal recognize that the calling terminal is a terminal having a telephone number registered in the group, and the terminal registered in the group calls the terminal. If so, it is checked whether the telephone number registered in another group is busy, and if so, a busy tone or message is returned to the calling terminal. If it is not during a call, it recognizes whether a branch number is attached to the telephone number of the connection destination, and if the branch number is attached, calls the telephone number registered in the group + the branch number. If there is no branch number, the incoming call is made as a normal outside line. In this case,
By storing in a computer system whether the call is within a group or a normal outside line, separate charge systems can be provided.

FIG. 4 shows an operation when a terminal having this function receives a call. When an incoming call arrives, the base station and the computer system check whether the terminal having the telephone number is busy, and if so, return a busy tone or message to the calling terminal. If you are not on a call, the phone recognizes that it is a phone number with a branch number.
An incoming call is made to the terminal having the branch number. If there is no branch number, a call is made to the representative branch number of the group.

[0010] When registering in a group, it is necessary to individually assign a branch number to each terminal and each terminal, and to register a representative branch number.

[0011]

According to the present invention, as described above, the present portable telephone system is slightly modified to provide a portable telephone system as shown in FIG.
As shown in the above, there is an effect that the burden on the user when contracting for a plurality of devices in the conventional telephone number assignment system is reduced.
