The numbers 010-444-4444, 010-555-5555, and 010-666-6666 are registered.

In the second step, the wired telephone terminal collects the location information of the registered mobile communication terminal, converts the information with its own number into a DTMF signal or a contract signal, and transmits the information to the database register of the wired telephone company. 21, 22 collects the registered mobile communication terminals 11, 12, 13, 14, 15, and 16 as RF signals, and DTMF or the number of the mobile communication terminals 12, 13, 15, and 16 detected therein. It converts into a contracted signal, connects it to a dedicated number for registration, and transmits it. That is, the wired telephone terminal 1 (21) is the number of the mobile communication terminals 12, 13 detected from the registered numbers of Figure 2 010-222-2222 and 010-333-3333, and the wired telephone terminal 2 (22) Among the registered numbers of FIG. 3, the numbers of the mobile communication terminals 15 and 16 are 010-5555-5555 and 010-666-6666, which are exclusive numbers for registration in the database 50 of the wireline communication company. It connects to 000-0000 and transmits. The wired telephone terminals 21 and 22 collect the numbers of the mobile communication terminals 11, 12, 13, 14, 15, and 16 detected as RF signals at predetermined time intervals, and compare the information with the information recorded in the storage unit. If there is, update the information by connecting to 080-000-0000.

Referring to the third step of storing the mobile communication terminal number for each wired telephone terminal in the database of the wired telephone company, the wired telephone terminals 21 and 22 are connected to 080-000-0000 through the wired telecommunications exchanger 30. It is stored in the database register 50 through the AD converter 40 which converts the DTMF or the contracted signal which is the transmitted analog signal into a digital signal. That is, the information transmitted from the wired telephone terminal 1 (21) and the wired telephone terminal 2 (22) is stored in the database register 50 in the form as shown in FIG. Here, the data of part B of FIG. 4 does not exist.

The fourth step, which is registered in the landline telephone terminal and calls the received number from the mobile communication terminal in the area to the landline telephone terminal, is described in the landline telephones 21 and 22 and the mobile communication terminal 12 in the area. , 13, 15, and 16) calls the receiving number through the keypad, the switching switch of the mobile communication terminal is activated and the communication with the base station is interrupted and the communication with the landline telephone terminals (21, 22) to be received by the landline telephone terminal. Call the number. For example, when the mobile phone 2 (12) calls the mobile phone 5 (15), the mobile phone 2 (12) is in the area of the landline telephone terminal 1 (21) to communicate with the landline telephone terminal 1 (21) and the number to receive Call 010-555-5555.

In the fifth step, the wired telephone terminal describes the step of calling the received number to the wire carrier communication switch, and the wired telephone terminal 21 hooks off and connects with the wire carrier communication switch 30 and calls the received request number DTMF signal. To make a call. That is, the DTMF signal of 010-555-5555 is transmitted.

Referring to the sixth step of retrieving the number of the landline telephone terminal associated with the received reception number, the information stored in the database register 50 before the landline telephone exchange 30 connects to the mobile telephone exchange 60. Search 010-555-5555 at (100) and extract 777-2222 of the wired telephone terminal 2 (22) associated with the retrieved 010-555-5555.

The seventh step is to connect to the number of the landline telephone terminal, if found, and to transmit the number to be received with the CID in the contracted form. It connects to 777-2222 of terminal 2 (22) and transmits a number to be received together with the CID in a contracted form.

In the eighth step, the step of wirelessly calling a reception number from the receiving landline telephone terminal is described. The landline telephone terminal 22 recognizes the CID transmitted and the number to be received at the same time as the call from the wireline communication switch 30. The mobile communication terminal 15, 010-555-555, is called with an RF signal that can communicate with the number to be received.

In the ninth step, the receiver performs a connection operation. The receiver of the mobile communication terminal 15 rings by the call of the wired communication terminal device 22 so that the receiver can be connected.

In the tenth step, when the wired telephone terminal device hooks off and transmits a communication between the mobile communication terminal and the wired communication company exchange period, the wired telephone terminal device 22 detects a connection operation of the receiver and hooks off the mobile communication. The communication between the terminal 15 and the wired communication company switch 30 transfers the voice analog signal by the RF signal to both sides.

It is connected to the 010-444-4444 through the mobile carrier switch 60. That is, this example is an example of the mobile phone 2 (12) and the mobile phone 4 (14) of Fig. 1 in which both the wireless communication of the transmitting side and the receiving side are converted into the one wireless communication.

If the called party is a landline telephone terminal, if the number called in the sixth step is a regular telephone, it is directly connected at the wired telephone exchange without searching. In other words, the mobile phone 2 (12) and the wired communication terminal 4 (24) is an example of converting one side wireless communication to both sides wire communication.

In the case where the transmitting side is a general telephone and the receiving side is a mobile communication terminal device in the area of the landline telephone terminal, the mobile telephone terminal device calls the mobile communication terminal apparatus. In other words, this is an example of the wired telephone terminal 3 (23) and the mobile phone 5 (15) has been converted from one side wireless communication to both sides wired communication.

Under the negotiation of the line transfer between the mobile communication company and the wired communication company, if the sending mobile communication terminal device is out of the area of the wired telephone terminal device, the recipient information is transmitted from the mobile communication operator switch to the wired communication exchange. Will be proceeded to. In other words, this is an example of the mobile phone 1 (11) and the mobile phone 5 (15) has been converted from both sides of the wireless communication to one side of the wireless communication.

In the above examples, the phone number of the mobile communication terminal device is used as it is, and in the form of conversion, a wired telephone number is given one-to-one using an idle virtual wired telephone number from a wire carrier and registered in the above-mentioned wired telephone terminal device. The same effect can be obtained by substituting all the numbers for the mobile communication terminal device such as the number to be stored in the database of the wired communication company, the number to be dialed, and the like. That is, the telephone number of the mobile communication terminal device has two numbers, a wireless communication telephone number and a wired communication telephone number. In this case, the wired communication company's database format includes a mobile communication terminal device which is not registered in the area of the wired telephone terminal device among the mobile communication terminals to which the virtual number is assigned, and is a database in which the virtual number and the number of the mobile communication terminal device are linked. As shown in Fig. 4, the storage format includes up to 200 pieces of data. By such a storage format, when the mobile communication terminal device calls a virtual number while the mobile communication terminal device is out of the area of the wired telephone terminal device, the wired telephone terminal connected in the sixth step is retrieved by the wired telephone exchange. Since the search is not possible, the phone number of the connected mobile communication terminal is searched and connected. That is, if 444-4444 is called, 010-444-4444 is searched and connected.

A mobile communication terminal device and a wired telephone terminal device are manufactured and used to achieve the above object. However, the mobile communication terminal device may be manufactured and used separately as a device connected to a connection part of an existing mobile communication terminal. In the terminal device can also be manufactured and used as a device connected in parallel to the wired network.
