Abstract

PURPOSE:To prevent the wrong use by giving two peculiar numbers, namely, a dial number and a terminal number to a mobile terminal and collating these numbers to identify whether a call is correct or not when call originating and terminating are controlled. CONSTITUTION:When receiving a subscriber number D of a mobile terminal 1, which is found distinctly on a telephone directory or the like, from the fixed network side, a mobile communication exchange 5 identifies a home memory station 7, where the device number of the mobile terminal 1 is stored, in accordance with the subscriber number D and transmits the subscriber number D through a common line signal path 6. The home memory station 7 reads out a device number X corresponding to the subscriber number D of the mobile terminal 1 and returns the subscriber number D and the device number X to the mobile communication exchange 5 through the common line signal path 6. When the mobile communication exchange 5 transmits the received device number X through a control line 4, a radio base station 3, and a radio channel 2, the regular mobile terminal 1 receives the device number X and transmits a subscriber number ID stored in the mobile terminal 1 to the exchange 5 through the radio channel 2, the radio base station 3, and the control line 4. The exchange 5 checks whether the subscriber number D and the subscriber number ID coincide with each other or not.

Traditionally, in this type of mobile communication, each mobile subscriber (
A unique dial number (hereinafter also referred to as subscriber number) is given to each mobile terminal, and the caller dials this subscriber number and transmits this subscriber number wirelessly from the wireless base station via the mobile exchange. Broadcasts are made within the base station area via lines, and incoming calls are connected to mobile terminals. In this way, mobile terminals are only connected to the network via wireless lines, and unlike regular telephones, there is no physical wired connection.

As mentioned above, in mobile communications, mobile terminals are connected to the network via wireless lines, so even if the mobile terminal is lost or used by a third party, the conventional subscriber number will not be broadcast. Although the incoming connection is made by using the network, the disadvantage is that such unauthorized use cannot be detected by the network.

Furthermore, in order to prevent such unauthorized use, it is necessary to abolish the subscriber number of the lost mobile terminal and assign a new number as soon as the loss is discovered, which may cause problems in terms of subscriber number capacity. Its shortcomings were also terrible.

In addition, when making an outgoing connection from a mobile Gs terminal, the subscriber number of the calling mobile terminal is simultaneously sent from the terminal to the network together with the subscriber number of the other party, but in this case as well, it can be used illegally (for making calls) by a third party. In order to prevent this, it was necessary to make the mobile terminal's subscriber number obsolete.

Furthermore, since there is only one unique number for a mobile terminal, which is the subscriber number that is open to the public, if a call is made with a subscriber number set on a forged mobile terminal, it will not be able to be checked by the network, and the original subscriber number will be lost. There was a drawback that the person was charged a fee. Furthermore, since the subscriber number is used for incoming calls, even counterfeit mobile terminals can respond.

The purpose is to provide such a signaling procedure.

That is, in the present invention, a unique dial number and a separate unique terminal number (hereinafter also referred to as aircraft number) are assigned to a mobile terminal, and a correspondence table of the two unique numbers is provided in the network. When a mobile terminal makes an outgoing call, if the two unique numbers sent from the mobile terminal match the correspondence table set up in the network, the outgoing connection is established, and when the mobile terminal receives a call, the network connects the originating side. The dialed number from the mobile terminal is converted into a terminal number and sent to the mobile terminal, and the dialed number returned from the mobile terminal is checked to see if it matches the dialed number from the calling party. In the prior art, only one unique dial number was assigned to a mobile terminal, but the present invention provides a mobile terminal with a dial number and a terminal number. This system differs from conventional systems in that it assigns two unique numbers, 1 and 2, and checks these numbers to determine whether the call is a valid call or not, when controlling incoming and outgoing calls.

If this mobile device becomes unused due to theft or discontinuation, the correspondence table between subscriber number and device number will be rewritten at the home memory station, so Since a different machine number will be sent to the subscriber number called from the fixed side, the mobile machine will not be able to receive this number and will not be able to connect. Since the correspondence relationship between the two terminals is different, the subscriber number from the mobile terminal and the subscriber number from the fixed side do not match, so the exchange considers this mobile terminal to be an unauthorized user and does not connect it.

In mobile communications that enable communication with mobile terminals via telephone networks and wireless lines, a dial number unique to the mobile terminal and a terminal number unique to the mobile terminal are assigned to the mobile terminal. means for storing a correspondence table between the dialed number and the terminal number for each mobile terminal, and in the control of incoming calls to the mobile terminal, when the network receives the number dialed by the caller, the dialed number is Based on the correspondence table, it is converted into a terminal number and sent to the mobile terminal, and the mobile terminal that receives this returns its own dialed number, and the network uses this dialed number and the dialed number received earlier from the caller. The incoming call is connected only if there is a match.On the other hand, when making an outgoing call from the mobile terminal, the mobile terminal sends its dialed number and terminal number together with the destination number to the network, and the above-mentioned correspondence is applied within the network. A mobile terminal identification method is characterized in that a calling request from a mobile terminal is accepted only when there is a matching dial number and terminal number by checking a table.
