Description

Description: TECHNICAL FIELD The present invention relates to a communication terminal device for performing caller identification in an ISDN (Integrated Services Digital Network).

(Prior Art) (1) It is impossible for a telephone connected to a conventional analog telephone network to identify and notify a caller before a response due to the nature of the analog telephone network. In this case, a response is made once, and the PB signal is transmitted to the other party as a personal identification number.

(2) In the ISDN network, the dialing number is displayed in a visual display using the information of the calling number or calling sub-address. There is no example in which the numbers set in advance are compared, and when they match, a PB signal corresponding to the calling number or calling sub address is broadcast to distinguish the calling party.

The called subaddress is used to individually receive a call to a plurality of terminals that can be connected to one ISDN line. The called subaddress is used as a personal identification number, and the called subaddress of the calling side at the time of receiving a call, There is no device for notifying the PB signal corresponding to the called sub address when the called party compares and compares the called sub address set in advance.

(Problems to be Solved by the Invention) As described above, when a conventional analog telephone network is used to connect and use a telephone to identify a caller and notify a specific ringing tone at the time of receiving a call, the incoming call is After receiving a response, it is necessary to receive a special signal to identify the caller.
There is a drawback that the caller needs to perform operations such as pressing the push button every time a call is made and transmitting a PB signal.

In an ISDN network, a caller is not identified at the time of an incoming call and is not reported by PB sound.

In addition, it is not used to identify the caller at the time of an incoming call and to notify by a PB sound when the call is used as a destination subaddress password of the ISDN network.

(Means and Actions for Solving the Problems) In order to solve the above-described problems, the present invention identifies a calling number or calling sub-address at the time of an incoming call, notifies a PB signal corresponding to the calling number or calling sub-address, The caller is identified by distinguishing it from the ring tone in the case of (1).

Also, when a call arrives, the destination sub-address is identified, a PB signal corresponding to the destination sub-address is transmitted, and distinguished from the ring tone in other cases, so that a specific caller is notified of the destination sub-address as a personal identification number. It is possible to notify that an incoming call has been received.

Embodiment An embodiment of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a functional block diagram of a communication terminal device according to an embodiment of the present invention. A driver / receiver 101, a layer 1.2 control unit 102, a layer 3 control unit 103, a man-machine control unit 104, a man-machine input / output unit 105 , PB oscillator 106, B channel selector 10

0, a handset 111, a speaker 112, a display unit 113, dial keys, and function keys 114.

In an ISDN network, a calling number, a calling subaddress, and a called subaddress are sent from a calling side when receiving a call.

The calling number, calling subaddress, and called subaddress transmitted by the caller are sent to the man-machine control unit 104 via the driver / receiver 101, the layer 1.2 control unit 102, the layer 3 control unit 103, and the man-machine control unit 104. Reportedly. The man-machine control unit 104 sends the calling party's calling number or calling sub-address
The number set in advance by the dial key and the function key 114 is compared with the man-machine control unit 104, and when the numbers match, the man-machine control unit 104 uses the path of the PB signal transmitter 106-analog signal processing circuit 109-speaker 112. A PB signal corresponding to the calling number or calling subaddress is transmitted to distinguish the calling party.

If an arbitrary number (four digits in the ISDN network) is set as the destination sub-address in the man-machine control unit 104, the destination sub-address sent by the calling side is identified by the man-machine control unit 104, and if it matches the preset number. The man-machine control unit 104 sends out a 4-digit PB signal corresponding to the destination sub-address on the path of the PB signal transmitter 106, the analog signal processing circuit 109, and the speaker 112, and knows the destination sub-address as a password. Notify that the call has been received from the caller.

(Effect of the Invention) As described above, the PB signal corresponding to the calling number, the calling subaddress and the called subaddress at the time of an incoming call is notified by the calling number, calling subaddress and called subaddress identification according to the present invention, so that the incoming call can be answered before the incoming call is answered. The identification of the caller and the identification of the limited caller who knows the personal identification number become possible, and the practical effect is extremely large.

Note that the PB signal transmitter is used in digital communication terminals to enable access to existing analog telephone services.
It generally has a signal transmission function (in-channel PB signal transmission function), and the PB signal transmitter used in this function can be shared with the function of the present invention, so that the equipment price does not increase. realizable.

Claims (2)

(57) [Claims] (1) connecting to an ISDN network (integrated digital communication network);
When the calling party's calling number or calling subaddress is compared with the number set in the called party on the terminal device that can determine the other party's number by calling number notification (calling number + calling subaddress) before answering the incoming call, and they match. A communication terminal device having an identification reception function characterized in that a plurality of digits of a PB signal corresponding to a calling number or a calling sub address are notified when a call is received and a caller is distinguished. 2. Connected to an ISDN network (integrated digital communication network),
In a terminal device capable of discriminating the called number notification (called sub address) before answering the incoming call, a called sub address that can be arbitrarily set by the user of the terminal device is used as a password between the calling side and the called side. When the subaddress information sent from the calling side at the time of the incoming call is compared with the destination subaddress set in advance on the called side, if there is a match, a PB signal of multiple digits corresponding to the destination subaddress is notified at the time of the incoming call and the call is made. A communication terminal device having an identification incoming call function characterized by distinguishing persons.
