The generated message is transmitted to the calling side. The facsimile transmission is executed when there is no cancel request from the calling side after referring to the transmitted message. The facsimile transmission is suspended when there is a cancel request.

Description

  The present invention relates to a facsimile erroneous transmission preventing apparatus, a facsimile erroneous transmission preventing system, a method thereof, and a program thereof during facsimile transmission.

  In offices and general households, information is widely transmitted and received using a facsimile (facsimile).

  In a facsimile, transmission data is generated by reading information on a document on the transmission side or creating data on a computer in compliance with the facsimile standard. Then, the generated transmission data is subjected to signal processing such as data compression and modulation, relayed through a communication line, and information is restored by demodulating the signal on the receiving side.

  A public switched telephone network is often used as a communication line for facsimile, but an IP communication network that does not use a telephone switch such as an IP (Internet Protocol) telephone, a LAN (Local Area Network), or the Internet is used. It is also possible. An example of a standard that uses such an IP communication network is InternetFAX.

  A facsimile using an IP communication network such as Internet FAX can transmit and receive information as a facsimile on the IP communication network by conforming to a protocol called FoIP (Fax over IP).

  Also, by providing a gateway between the IP communication network conforming to FoIP and the public switched telephone network, general facsimiles connected to the public switched telephone network can transmit and receive information via the IP communication network. Is possible.

  Such technologies relating to FoIP are described in Patent Document 1 and Patent Document 2.

  Patent Document 1 discloses a technique for controlling the transmission order of faxes when using Internet FAX. Patent Document 2 discloses a technique for managing an address book recorded inside a copying machine with a built-in Internet FAX or Internet Fax function.

  As described above, by using the techniques described in Patent Document 1, Patent Document 2, and the like, facsimiles can transmit and receive information via the IP communication network. However, these technologies have the following problems.

  Explain the problem. Generally, at the time of fax transmission, the sender inputs the recipient's fax number and executes transmission. However, an input error may occur at the time of inputting a fax number. In such a case, information is transmitted to an undesired recipient, and as a result, information is leaked. The occurrence of such a situation should naturally be avoided, but since there is no confirmation information other than the fax number at the time of transmission, in most cases, the user is unaware of erroneous input. Therefore, it has been difficult to prevent input mistakes.

  In addition, as described in Patent Document 2, there is a method in which an address book is provided in the facsimile and a destination is selected while referring to the address book. In this case, the destinations are registered one by one. Or new additions at a later date. Furthermore, if the number of facsimiles becomes plural, this effort will increase. In addition, it may be possible to mistakenly register a fax number or transmission destination during registration.

  In addition, even if the address book is used, if the fax number on the recipient side changes, there is no means (such as an announcement or message) to notify that the fax number has been changed when sending a fax. Transmission fails. When the transmission fails, the user cannot recognize the cause on the transmission side. Therefore, it becomes necessary to confirm the new fax number by other means such as confirmation of the number by telephone between the calling side and the receiving side.

  Therefore, the present invention provides an apparatus for preventing erroneous transmission of a facsimile and a facsimile error that can prevent a situation in which a transmission destination is erroneously transmitted when performing communication by fax via an IP communication network. An object is to provide a transmission prevention system, a method thereof, and a program thereof.

  Next, embodiments of the present invention will be described in detail with reference to the drawings. In the following description, a facsimile via the IP telephone network is referred to as “Fax”.

  First, an outline of the present embodiment will be described. In this embodiment, at the time of fax transmission, the incoming side information (company name, organization name, user name, etc.) associated with the transmission number is searched on the network side, and is displayed as a fax message or notified by voice to the transmission user. To do. As a result, the user on the calling side can confirm whether or not information is being transmitted to the correct incoming user, and erroneous transmission can be prevented with high reliability.

  In addition, since the fax subscriber information is managed on the network side, even if there is a change in the number on the receiving side, the fact and the new number can be notified to the calling side.

  As the message notification means, a fax message or a voice reproduction message is used. Since the fax message reception and voice playback functions are standard functions of a general fax transmitter / receiver, there is an effect that it is not necessary to modify the fax transmitter / receiver or introduce a new model. The above is the outline of this embodiment.

  FIG. 1 is a diagram showing the entire facsimile erroneous transmission prevention system according to this embodiment.

  Referring to FIG. 1, the present embodiment includes a communication carrier IMS (IP Multimedia Subsystem) network 100, an access network 201, an access network 202, a fax transmission / reception device 301 and a fax transmission / reception device 302. Further, the carrier IMS network 100 includes a fax authentication server 110 and a signaling node 120.

  The fax transmission / reception device 301 and the fax transmission / reception device 302 can transmit and receive facsimiles to and from each other via the communication carrier IMS network 100, the access network 201, and the access network 202. At this time, the fax transmission / reception device 301 and the fax transmission / reception device 302 transmit and receive a facsimile via the signaling node 120.

  The telecommunications carrier IMS network 100 is a network provided by a telecommunications carrier, and can perform communication based on IP.

  The fax authentication server 110 is a server that implements functions specific to the present embodiment. The fax authentication server 110 manages fax subscriber information and notifies the user on the transmission side of the fax subscriber information. The fax authentication server 110 is realized by incorporating software unique to the present embodiment into one or a plurality of server devices.

  The signaling node 120 is a call control device for realizing communication by fax between the fax transmission / reception device 301 and the fax transmission / reception device 302, and manages location information that is position information of the fax transmission / reception device 301 and the fax transmission / reception device 302. Here, as the location information, an IP address corresponding to each of the fax transmission / reception device 301 and the fax transmission / reception device 302 is assumed. The signaling node 120 can be realized by a subscriber information management server generally called HSS (Home Subscriber Server). The signaling node 120 is installed by a telecommunications carrier that provides the telecommunications carrier IMS network 100.

  The access network 201 and the access network 202 are networks for connecting to the carrier IMS network 100, and may be the Internet, or may be a telephone line network or a LAN. . In addition, other relay devices may exist in the network.

  In addition, the functions of the fax authentication server 110 and the signaling node 120 may be realized by a single device.

  The Fax transmission / reception device 301 and the Fax transmission / reception device 302 are devices for performing Fax transmission / reception. Since the fax transmission / reception device 301 and the fax transmission / reception device 302 do not need to include functions specific to the present embodiment, they can be realized by general-purpose fax transmission / reception devices. Further, the Fax transmission / reception device 301 and the Fax transmission / reception device 302 may include a function of reproducing a voice message as a telephone in addition to a function of performing transmission / reception of a Fax, but may not include a function of reproducing a voice message. . In the following description, the Fax transmission / reception device 301 is described as the transmission side, and the other Fax transmission / reception device 302 is illustrated as the reception side. It is not intended to limit. As described above, in the present embodiment, the Fax transmission / reception device 301 and the Fax transmission / reception device 302 can transmit and receive each other. Therefore, both may be a transmission side or a reception side. In the following description, when not referring to a specific Fax transmission / reception device such as the Fax transmission / reception device 301 or the Fax transmission / reception device 302, all the Fax transmission / reception devices are collectively referred to as a Fax transmission / reception device 300.

  The network configuration and the number of devices shown in FIG. 1 are merely examples, and can be arbitrarily changed as long as the gist of the present embodiment is not changed. For example, the functions of both the fax authentication server 110 and the signaling node 120 may be realized by one server device.

  Next, functional blocks included in the fax authentication server 110 will be described with reference to FIG. Here, FIG. 2 is a block diagram showing functional blocks included in the fax authentication server 110.

  Referring to FIG. 2, the fax authentication server 110 includes a signal transmission / reception unit 111, a SIP (Session Initiation Protocol) message processing unit 112, a fax subscriber information management database 113, and a message creation unit 114.

  In the signal transmission / reception unit 111, the fax authentication server 110 receives a request signal from the signaling node 120. Then, the SIP information included in the received request signal and the media reproduction capability information of the fax transmission / reception device 300 on the transmission side are acquired. Then, the acquired SIP information is input to the SIP message processing unit 112. On the other hand, the acquired media playback capability information is input to the message creation unit 114.

  The SIP message processing unit 112 analyzes the input SIP information and identifies the called fax number that is the fax number of the called fax transmission / reception device 300. Then, the incoming fax number is input to the fax subscriber information management database 113.

  The fax subscriber information management database 113 is a database that manages information of subscribers who subscribe to the information providing service using the fax authentication server 110. In the fax subscriber information management database 113, the fax number of the fax transmission / reception device 300 used by the subscriber and the called party information of the subscriber are stored in association with each other. Here, the receiving side information may be any information as long as it is useful information for the purpose of identifying the destination by the caller. The called party information is, for example, a company name, department name, organization name, and user name. In addition, for example, incidental arbitrary information such as a telephone number, an e-mail address, business days, business hours, and the like may be included.

  When the incoming call fax number is input from the SIP message processing unit 112, the fax subscriber information management database 113 searches the incoming call party information using the received incoming fax number as a search key. As a result, the callee information associated with the input callee fax number is acquired. The acquired called party information is input to the message creation unit 114.

  The message creating unit 114 creates a message for transmitting the input called party information to the calling party. In the present embodiment, two types of messages are assumed as messages: a fax message that is a message that conforms to FoIP and a voice announcement message that is a message that conforms to RTP (Real Time Protocol). The message creation unit 114 creates a fax message or a voice announcement message according to the media playback capability of the transmitting-side fax transmission / reception device 300 input from the signal transmission / reception unit 111. The notification of the media playback capability of the fax transmission / reception device 300 on the transmission side can be realized by a notification based on SDP (Session Description Protocol).

  In other words, if the calling fax transmission / reception device 300 has the ability to receive and play back a fax message, it creates a fax message, and the calling fax transmission / reception device 300 has the capability to receive and play a voice announcement message. If so, create a voice announcement message. In addition, when the fax transmission / reception device 300 on the calling side has the ability to receive and play back any message, both a fax message and a voice announcement message may be created, or either one set in advance may be created. You may make it do. In any case, the message creation unit 114 inputs the created message to the signal transmission / reception unit 111.

  The signal transmission / reception unit 111 transmits the message received from the message creation unit 114 to the fax transmission / reception device 300 on the transmission side via the signaling node 120.

  Next, functional blocks included in the signaling node 120 will be described with reference to FIG. Here, FIG. 3 is a block diagram showing functional blocks included in the signaling node 120.

  Referring to FIG. 3, the signaling node 120 includes a call control unit 121, a location information database 122, and a signal transmission / reception unit 123.

  The location information database 122 is a database in which location information is stored.

  The call control unit 121 performs call control within the communication carrier IMS network 100. Specifically, communication call control (IP address notification, user authentication, etc.) performed by the fax transmission / reception device 300 and the fax authentication server 110 is performed based on the location information stored in the location information database 122. The location information also includes information indicating whether the user of the fax transmission / reception device 300 is a subscriber who subscribes to an information providing service using the fax authentication server 110. When it is determined that the fax transmission / reception device 300 on the transmission side is a subscriber of the information providing service, the call control unit 121 transfers request information indicating that the fax is to be transmitted to the fax authentication server 110.

  The signal transmission / reception unit 123 is a communication unit for realizing transmission / reception of signals with the Fax authentication server 110 and the Fax transmission / reception device 300.

  Next, a method for operating information of subscribers who have subscribed to the information providing service using the fax authentication server 110, particularly a method for registering information in the fax authentication server 110 will be described. Note that the description of the registration described below is merely an example of a specific operation method of the present embodiment, and such an operation method does not necessarily have to be performed. That is, it is not an explanation for limiting the operation method of the present embodiment.

  The Fax authentication server 110 exists in the telecommunications carrier IMS network 100 and is managed by a network management carrier or a company that implements an information providing service. Thus, one of the features of this operation method is that the fax authentication server 110 is hidden from the user of the fax transmission / reception device 300 as an end user.

  That is, the end user cannot directly access the registered contents of the fax authentication server 110 to change or add information registered without permission. Further, the end user does not need to be aware of the fax authentication server 110. The end user can receive the receiving side information without being aware of the Fax authentication server 110 by attempting Fax transmission using the Fax transmission / reception device 300.

In the Fax subscriber information management database 113 of the Fax authentication server 110, data is registered in the server by the following procedure.
1. When the end user wants to use the fax information providing service, the end user makes a use application and makes a contract with a network management carrier or company.
2. When applying for a contract, the applicant decides information to be displayed as incoming side information for the Fax transmission side. As described above, the called party information includes a telephone number, a called party name, a company name, and the like.
3. The network management carrier or the person in charge of the company has The information applied in step 1 is registered in the fax subscriber information management database 113 of the fax authentication server 110 in association with the fax number.
4). Thereafter, when the fax number is changed, the fax number before the change and the fax number after the change are linked and registered in the fax subscriber information management database 113. In addition, the fact that the fax number has been changed is added as information on the receiving side.
5. Regardless of whether the fax number has been changed or not, the callee side information is corrected according to the application from the user. For example, when the department name or telephone number is changed, the receiving side information is corrected according to the application from the user.

  Here, when the Fax authentication server 110 is managed under the telecommunications carrier that provides the telecommunications carrier IMS network 100, the Fax authentication server 110 cooperates with the signaling node 120 that is a server that manages subscriber information. It is also possible to acquire and register user information. In other words, the application for using the fax information providing service may be made together with the network use application so that one telecommunications carrier registers or changes both the subscriber information of the fax authentication server 110 and the location information of the signaling node 120. .

  Further, registration information may be exchanged between the fax authentication server 110 and the signaling node 120 as necessary. For example, when a user of a certain fax transmission / reception device 300 has a contract renewal or a user has moved, the fax number may change. In such a case, the telecommunications carrier providing the telecommunications carrier IMS network 100 changes the location information in the signaling node 120. When such a change is made, this fact may be transmitted from the signaling node 120 to the fax authentication server 110.

  Since the normal role of the signaling node 120 is call control, it is not necessary to grasp the subscriber information itself for providing Fax information, and it is sufficient to grasp the location information. Therefore, in the present embodiment, load distribution is achieved by causing the signaling node 120 and the fax authentication server 110 to share roles. Further, by performing the role division in this way, it is possible to cope with a business operator that provides the communication carrier IMS network 100 and a business operator that provides the fax information provision service.

  Further, for example, when a certain company installs the fax authentication server 110 for its own company, it is possible to provide the fax information only when the fax is exchanged within the certain company.

  Subsequently, the operation of the present embodiment will be described with reference to the flowcharts of FIGS.

  First, the normal operation of the present embodiment will be described with reference to FIGS. Here, the normal time is a case where the fax subscriber information management database 113 of the fax authentication server 110 stores the fax number of the called fax transmitting / receiving device 300 and the called party information. FIG. 4 illustrates a case where the user on the transmission side does not cancel the fax transmission. On the other hand, FIG. 5 demonstrates the case where the transmission side user performs the cancellation operation | movement of Fax transmission.

  FIG. 6 illustrates an operation when subscriber information is not registered in the fax authentication server 110 and retrieval of the called party information fails. Furthermore, FIG. 7 illustrates an operation when the fax number on the receiving side is changed.

  In the following description, it is assumed that the Fax transmission / reception device 301 is the transmission side and the Fax transmission / reception device 302 is the reception side, regardless of the drawings. In each drawing, the same reference numerals are assigned to the same processes.

  First, a description will be given with reference to FIG.

  1. The transmitting-side fax transmission / reception device 301 receives a transmission destination number input from the user and executes transmission (step S1). Along with this, a message indicating that Fax is being transmitted is displayed (step S2).

  2. The calling Fax transmission / reception device 301 transmits an INVITE message to the signaling node 120 (step S3). The SDP of this INVITE message body includes the presence / absence of two capabilities, ie, the presence / absence of voice reception capability and the presence / absence of fax reception capability, as the media playback capability of the fax transmission / reception device 301. The signaling node 120 that has received the INVITE message returns 100 Trying indicating that processing is in progress (step S4).

  3. Based on the location information, the signaling node 120 determines that the user of the fax transmission / reception device 301 that is the transmission side of the INVITE message received in step S3 is a subscriber of the fax information providing service (step S5).

  4). The signaling node 120 transfers the INVITE message to the fax authentication server 110 (step S6).

  5. The fax authentication server 110 performs the following operation on the received INVITE message.

  5.1. First, the Fax authentication server 110 that has received the INVITE message returns 100 Trying indicating that processing is in progress (step S7). Then, the media playback capability of the fax transmission / reception device 301 described in accordance with SDP included in the INVITE message is analyzed. Then, the media transmission capability corresponding to the media playback capability of the fax transmission / reception device 301 is set as an SDP answer to the 183 Session Progress message and returned to the fax transmission / reception device 301 on the transmission side. That is, if the fax transmission / reception device 301 has a voice reception capability, the fax authentication server 110 returns a message indicating that a voice message can be transmitted as the media transmission capability. On the other hand, if the fax transmission / reception device 301 has the fax reception capability, the fax authentication server 110 replies that the fax message can be transmitted as the media transmission capability. These replies are made through the signaling node 120 (steps S8 and S9). When receiving the 183 Session Progress message, the fax transmission / reception device 301 transmits PRACK to the fax authentication server 110 as a delivery confirmation (step S12 and step S13). The fax authentication server 110 that has received PRACK returns 200 OK.

  5.2. The fax authentication server 110 obtains the called party number contained in the received INVITE message, and searches the called party information management database 113 for the called party information of the called fax transmission / reception device 302 (step S10).

  5.3. 5.2. From the information retrieved in (1), a message is generated as in the following “5.3.1.” Or “5.3.2.” (Step S11). Creating a message according to the reception media type corresponding to the media playback capability of the fax transmission / reception device 301 on the transmission side, such as the following “5.3.1.” Or “5.3.2.” This is one of the features of the embodiment. Here, steps S12 to S15 are common regardless of the media playback capability of the fax transmission / reception device 301, and will be described in advance. When receiving the 183 Session Progress message, the fax transmission / reception device 301 transmits PRACK to the fax authentication server 110 as a delivery confirmation (step S12 and step S13). The Fax authentication server 110 that has received PRACK returns 200 OK (Steps S14 and S15).

  5.3.1. If it is determined from the analysis result of 5.1 above that the transmitting-side fax transmission / reception device 301 can receive only a fax, a fax message including information on the receiving-side fax transmission / reception device 302 is created and conforms to the FoIP protocol. The data is sent to the fax transmission / reception device 301 on the transmission side (step S16). The sent message is reproduced by the fax transmission / reception device 301 (step S17).

  5.3.2. On the other hand, if it is determined from the analysis result in 5.1 above that the transmitting-side fax transmission / reception device 301 has the voice reception capability, a voice message including information on the receiving-side fax transmission / reception device 302 is created and RTP (Real In accordance with Time Protocol, the data is sent to the fax transmission / reception device 301 on the transmission side (step S16). The sent message is reproduced by the fax transmission / reception device 301 (step S17).

  6). If the message is transmitted in step S16, the Fax authentication server 110 activates a Cancel waiting timer (step S18). Although the length of the Cancel waiting timer is arbitrary, it is sufficient for the user using the fax transmission / reception device 301 to refer to the message reproduced in step S17 and to confirm that the destination of the fax is the correct incoming side. Try to be length.

  7). If the user of the calling fax transmission / reception device 301 does not press the Cancel button before the canceling waiting timer ends (Time out), the fax authentication server 110 transfers the INVITE message to the receiving fax transmission / reception device 302 ( In step S20, normal fax transmission / reception is performed (steps S21 to S24). Specifically, the INVITE message is transmitted from the fax authentication server 110 to the signaling node 120 (step S20). The signaling node 120 that has received the INVITE message returns 100 Trying indicating that processing is in progress to the fax authentication server 110 (step S21). Next, an INVITE message is transmitted from the signaling node 120 to the fax transmission / reception device 302 (step S20). The signaling node 120 that has received the INVITE message returns 100 Trying indicating that processing is in progress to the signaling node 120 (step S21). Finally, normal fax transmission / reception is performed between the fax transmission / reception device 301 and the fax transmission / reception device 302 (step S24).

  8). On the other hand, a case where the Cancel button is pressed down by the user of the transmitting-side fax transmission / reception device 301 before Time out will be described with reference to FIG.

  Up to step S18, the operation is the same as that described above with reference to FIG. As described above, the fax authentication server 110 activates the cancel waiting timer (step S18). And before it becomes Time out, the fax transmission / reception device 301 on the transmission side accepts pressing of the Cancel button from the user (step S31).

  Then, the Fax transmission / reception device 301 that has received the pressing of the Cancel button transmits a CANCEL message to the signaling node 120 (step S32). The signaling node 120 that has received the CANCEL message returns 200 OK to the fax transmission / reception device 301 (step S33) and transfers the received CANCEL message to the fax authentication server 110 (step S34). The Fax authentication server 110 that has received the CANCEL message returns 200 OK to the signaling node 120 (step S35). Further, the fax authentication server 110 stops the Cancel waiting timer and discards the INVITE message received in step S6 (step S36). Subsequently, the fax authentication server 110 transmits 487 Request Terminated indicating that the request has been terminated by CANCEL to the fax transmission / reception device 301 via the signaling node 120 (step S37 and step S38).

  Finally, the Fax transmission / reception device 301 transmits ACK to the Fax authentication server 110 via the signaling node 120, whereby Fax transmission / reception is stopped (Step S39 and Step S40).

  Next, with reference to FIG. 6, an operation in the case where the retrieval of the incoming side information of the incoming fax transmission / reception device 302 has failed will be described. First, the operation up to step S9 is the same as the operation described with reference to FIG. 4 and FIG.

  1. In the processing of FIG. 4 and FIG. 5, when the incoming side information is searched in step S10, the search is successful. That is, the incoming side information of the incoming fax transmission / reception device 302 is stored in the fax subscriber information management database 113. On the other hand, in the operation shown in FIG. 6, although the user of the fax transmission / reception device 301 on the transmission side can be determined as a subscriber of the fax information providing service in step S5, the fax subscriber information management is performed. It is assumed that the incoming side information is not stored in the database 113 and the search has failed.

When retrieval of the Fax transmission / reception device 302 information from the Fax subscriber information management database 113 fails (step S51), the Fax authentication server 110 makes an inquiry in accordance with the Diameter protocol to make the incoming call to the signaling node 120. The location information of the fax transmission / reception device 302 is inquired (step S52).
2. The signaling node 120 responds with the location information of the recipient in response to the request from the fax authentication server 110 (step S53).
3. The fax authentication server 110 generates a message including a warning message and location information (step S54). Here, the warning message is information for notifying the user that the callee side information could not be acquired, and may be any information. Examples of the location information include a provider name that can be specified from an IP address, an area where the incoming fax transmission / reception device 301 is installed, and the like. In addition, the name of the provider that provides the communication provider IMS network 100 may be included. In addition, a company name or a school name may be included.
