2. Description of the Related Art Japanese Unexamined Patent Application Publication No. 9-46501 discloses a related document relating to a process of preventing a false incoming call, for example, when an incoming fax is received by an extension telephone connected to a PBX, the incoming call is erroneously received by a caller. Has been proposed. This device sets an extension telephone number in advance, and detects that there was an erroneous call other than the fixed telephone and the FAX.
X originator is transmitted by voice data stored in advance.

For example, Japanese Patent Application Laid-Open No. 7-84907 discloses a method in which a FAX server receives a fax, records the source and destination of the fax, and determines whether or not the LAN terminal connected to the FAX server is addressed to itself. By doing so, a facsimile server has been proposed in which document data is not lost even if there is an erroneous transmission to a LAN terminal that is not the original destination.

[0004] In these techniques, it is necessary to specially prepare a device for setting information on the called side, and it is only necessary to monitor erroneous calls to a PBX or the like, and it is difficult to apply it to a general fixed telephone. is there.

The above prior art has the following problems.

The first problem is that it is necessary to specially prepare a device for presetting information or data on the receiving side, which makes it difficult to apply to a general fixed telephone.
That's what it means.

The second problem is that erroneous calls to a PBX or the like are monitored, and it is difficult to apply the method to a general fixed telephone.

A third problem is that the notification of an erroneous incoming call to the calling side is voice guidance. The reason is,
When the voice guidance is issued from the receiving side, the voice is specially compressed in mobile communication, but is not compressed during non-telephone facsimile communication. This is because it is unlikely that the fax sender manually performs the communication even if the fax transmission is performed on a fixed network instead of the mobile fax communication.

[0013] Accordingly, the present invention has been made in view of the above-mentioned problems, and has as its object to provide a fixed telephone to a fixed telephone in the event of an incoming call to a general fixed telephone by mistake during a mobile fax communication. It is an object of the present invention to provide an erroneous incoming call processing method in mobile FAX communication that provides information on a voice and a transmission source and can notify the transmission source of information indicating an erroneous call.

Another object of the present invention is to control the provision of the information by a network-side ADP mounted on the exchange side, thereby eliminating the need for installing a special device on the transmitting / receiving terminal side.
An object of the present invention is to provide an erroneous incoming call processing method in X communication.

FIG. 1 is a diagram showing an erroneous incoming call control sequence according to an embodiment of the present invention, which is a control sequence when a general fixed telephone is erroneously received during a mobile fax communication. A control sequence according to the embodiment of the present invention will be described with reference to FIG. FIG. 4 is referred to for the configuration of the mobile FAX communication system.

When an erroneous call arrives at the fixed telephone 108, it is assumed that the fixed telephone can detect a voice such as "Yes, OO" or a surrounding noise. This voice is transmitted to a protocol control unit ("network-side AD") connected during non-voice communication in the exchange, particularly when the transmitting side is a facsimile.
P ”) 101, it is determined that an erroneous call is received, and the erroneous call information is transmitted to the CSI (Called Su).
bus identifier, and the CSI and a dummy DIS (Digita
l Identification Signal) to the transmitting FAX 103 via the mobile ADP 103.

At this time, when a voice is detected from the fixed telephone, a voice such as "I'm sorry."

On the transmission FAX 103 side, CSI and DIS
And receiving the TSI (Transmitting Subs
criber Identification) and D
CS (Digital Command Signa)
1) is sent out.

The network-side ADP 101 in the exchange receives this, reads source information (telephone number, etc.) from the TSI,
Following the “I ’m sorry” voice of the apologies above,
The sender's telephone number is guided by voice to the fixed telephone.

The TSI has data such as a telephone number and a sender, which are set on the transmitting fax side.

As a result, the operator of the landline telephone that has received an erroneous call can listen to the voice of the acknowledgment and obtain the transmission source information.

In the embodiment of the present invention, information indicating that the receiving side is a fixed telephone is also notified to the CSI to the transmitting FAX side by data so that the transmitting FAX side can confirm this. For example, data such as “ITE FAX Pear” is transmitted.

As a result, the operator at the transmitting FAX side can confirm that an erroneous incoming call has occurred.

However, since TSI and CSI are non-standard signals, they are limited to terminals conforming to these specifications.

For example, TSI has a maximum of 24 characters (underlined part)
ASCII code Is read and converted to speech,
Send to the landline that received the wrong call.

Also, the CSI is, for example, “FF 03 40 20
20 ・ ・ ・ 34 33 32 31 33 30 ”. When this is written as“ FAX ... ”, And send it to the sender.

The TSI and CSI are usually constituted by telephone number data. In the embodiment of the present invention, preferably, the transmitting FAX also reads and displays CSI other than the numbers from the receiving FAX. A fax terminal is used.

Therefore, for a FAX terminal that displays only numbers, a number that cannot be specified on the transmitting side, such as “99.”, is added after “FAX No.. Since the destination is "99.", it is expected that the sending FAX will have to check again.

FAX terminals that do not deal with TSI and CSI are considered to be rare, but in this case, call the landline phone, "I'm sorry. The sender is FAX and" unknown "."
Can be notified.

The mobile side ADP 104 and the network side ADP 1
01 performs ARQ control as described above,
The receiving side that normally receives the frame transmitted from the transmitting side returns an ACK.

Here, the network side A receiving the TSI and DCS
At the point where the DP 101 reads the TSI and outputs the voice to the fixed side, the network side ADP 101 causes the mobile side ADP 1
Returning the ACK to the ARQ frame from the ARQ 04 is stopped, and all NACKs are returned.

The mobile ADP 104 that has received the NACK enters retransmission control, repeats this, and ends abnormally, thereby terminating the erroneous incoming call control.

The timing of the abnormal termination depends on each FAX terminal and the mobile ADP, but is a timing at which this erroneous incoming call control can be performed at least.

As a result, in mobile fax communication,
In the case of an erroneous incoming call from a sending FAX to a fixed telephone, the receiving operator can recognize the voice of the apology and information on the other party
The operator on the transmitting side can also recognize that the receiving side is a fixed telephone or an erroneous call.
