DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a telephone, a facsimile,
(Facsimile) <br/> Ru relates to a suitable receiving terminal by using the like.

[0002]

2. Description of the Related Art In conventional telephones and fax machines,
For example, it is connected to an analog line (analog line network) having a 3.4 kHz frequency band, and in an in-channel system,
Call information (for example, "hello") and control information (for example, a telephone number of a partner for setting up a call, etc.) (hereinafter referred to as call control information) are transmitted. That is, as shown in FIG. 6, the call information and the call control information are transmitted without being distinguished physically or logically.

In such a telephone or a facsimile,
By personal identification information (for example, company name, department, name, etc. printed on the top of FAX paper output from FAX) for identifying the individual sender transmitted from the calling telephone or FAX after receiving the incoming call It is possible to confirm who is calling or faxing.

[0004] By the way, with the advent of, for example, the videotex system and the voice mail system due to the advance of information processing technology, a digital communication (line) network for integrating a communication system such as a telephone and a facsimile into these systems has been developed. For example, ISDN networks are becoming widespread. The ISDN network transmits call information and call control information in an out-channel manner. That is, in the ISDN network, as shown in FIG. 7, an information channel for transmitting call information (hereinafter referred to as B channel) and a signal channel for transmitting call control information (hereinafter referred to as D channel). Are logically separated.

[0005] Further, in the ISDN network, one line is composed of two B channels having a transmission rate of 64 kb / s and one D channel having a transmission rate of 16 kb / s, for example, so that call control information is transmitted. Since the capacity of the D channel is sufficiently large, in addition to the minimum necessary control information such as the other party's telephone number in the analog network,
For example, the subscriber (telephone) number (caller number) of the caller,
Arbitrary information of a predetermined length (hereinafter, referred to as user-user information) can be transmitted as call control information.

Note that the call control information is transmitted before the called party (the called party) answers.

In a telephone which can be connected to such an ISDN network, a telephone number of a caller stored in a built-in memory in advance and a call transmitted by a D channel before the called party answers. A response can be made only when the caller ID matches.

[0008]

However, since the caller number does not always correspond one-to-one with the individual caller, it is not possible to prove that the caller is himself at the time of calling. Therefore, there is a problem that the called party knows the calling party number (subscriber number) of the calling party, but cannot determine who the phone is from.

Therefore, as described above, it is confirmed who the telephone (or FAX) is from by the personal authentication information transmitted from the telephone (or FAX) of the calling side after receiving the incoming call to identify the individual sender. There is a way.

However, according to this method, the personal authentication information cannot be confirmed unless the called party has answered the call (after the incoming call has been answered), that is, since it is not known from whom, the incoming call ( Or FAX), for example, a call from a recruiter or a prank call (or FA
X) or a wrong telephone (or FAX), there is a problem that makes the user feel troublesome.

The present invention has been made in view of such circumstances, and it is an object of the present invention to confirm a caller before answering an incoming call.
