Description

  The present invention relates to a network facsimile apparatus that establishes a communication path by session control based on a session control protocol and performs facsimile communication.

  As one of the communication methods of network facsimile, a session control protocol (SIP ... Session Initiation Protocol) is used, and image data is transmitted by connecting a transmitter and a receiver to a peer-to-peer via a network such as the Internet. There is. In SIP, identification information (for example, a public line) for specifying a facsimile machine on a server called a SIP server (actually configured by a proxy server, a registration server, a location server, a redirect server, etc.) arranged on a network. When the transmitter sends a request to the SIP server with the destination FAX number, the SIP server receives the FAX number received from the transmitter. The IP address corresponding to is searched, and the call connection between the transmitter and the destination receiver is performed using the IP address.

  In addition, the SIP server provides a function for temporarily changing the IP address registered in association with the FAX number to an alternative address (redirect address), and transmits to the FAX number for which the alternative address is set. When there is a connection request from the machine, the SIP server notifies the transmitter that a substitute address is currently temporarily set and the substitute address as a redirect response.

  Such an alternative address may be a destination contrary to the sender's intention. Therefore, there is a network-compatible facsimile apparatus that prevents facsimile transmission to a terminal unintended by the sender by automatically interrupting communication when a redirect response is notified (see, for example, Patent Document 1). . Furthermore, in this apparatus, a permitted address to be permitted as an alternative address is registered in advance on the transmitter side, and only when the alternative address notified by the redirect response matches the permitted address, the destination indicated by the alternative address is automatically set. It is supposed to transfer.

Japanese Patent Laid-Open No. 2005-94662

  In the above-described technique, when a redirect response is received, the address is not transferred to an alternative address except for a preset permission address, so that transmission to an unintended destination of the sender is prevented. However, since there is only one alternative address that can be registered in the SIP server in association with each FAX number, the selection that can be made on the transmitter side that has received the redirect response is only a determination of whether or not to forward to that alternative address. There wasn't. For this reason, even if there are multiple terminals on the network that can be used as substitutes for a certain FAX number, the user on the transmitter side cannot select a transfer destination from the multiple substitutes. It was.

  In addition, it is assumed that the information about the alternative device is not sufficient simply by notifying the alternative address from the SIP server as a redirect response, and it is impossible for the transmitter side to determine what the destination is, and a plurality of alternative devices are notified. However, it is not possible to select an appropriate one that matches the intention of the sender.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 shows a configuration example of a network facsimile system 5 according to an embodiment of the present invention. The network facsimile system 5 is a facsimile system configured to perform call connection using a session control protocol, and to transmit image information by connecting the transmitter and the receiver to the peer-to-peer via the network 2. The SIP server 10, the transmission side facsimile apparatus 20, the reception side facsimile apparatus 30, and the redirect destinations 40a to 40c are connected to the network 2 such as the Internet. The devices 10, 20, 30, 40 a to 40 c connected to the network 2 are not limited to the illustrated number, and many devices may be connected.

  The SIP server 10 is actually composed of a plurality of servers such as a proxy server, a registration server, a location server, and a redirect server. The transmission-side facsimile device 20, the reception-side facsimile device 30, and the redirect destinations 40a to 40c are each configured as a network-compatible facsimile device that performs session control based on a session control protocol. Although not shown in the drawings, these are all a control unit having a CPU as a main part, a scanner unit for optically reading a document to acquire image data, a printer unit for printing an image on a recording paper, an operation screen display, and the like. An operation display unit that accepts user operations, a hard disk device that stores image data, and the like, a communication unit that communicates via the network 2, and the like.

  In the network facsimile system 5, the receiving facsimile machine 30 identifies to the SIP server 10 the identification information for identifying the machine itself and the address information on the network 2 (here, the IP address of the machine). Information (destination information) is registered in advance (FIG. 1, P1). In the present embodiment, it is assumed that the identification information for specifying the own device is a FAX telephone number (FAX number) on the public line.

  When the SIP server 10 receives a connection request from the transmitting facsimile machine 20 using the FAX number of the receiving facsimile machine 30 (P2), the SIP server 10 searches for an IP address registered in association with the FAX number and uses the IP address. Thus, a call connection between the transmitting side facsimile apparatus 20 and the receiving side facsimile apparatus 30 is performed. The image data transmission method after the call connection is arbitrary, and for example, a protocol based on Recommendation T.38 of ITU-T (International Telecommunication Union-Telecommunication sector) is used.

  In addition, the receiving-side facsimile apparatus 30 associates with the FAX number of the own machine, and receives destination information (specific information of the other machine) including an IP address of another machine different from the own machine (for example, an alternative machine such as the redirect destinations 40a to 40c). ) Can be requested to the SIP server 10 (P1 in FIG. 1). When there is a connection request from the transmitting facsimile machine 20 to the FAX number for which the redirect setting has been made (P2), the SIP server 10 displays the destination information of the redirect destination currently temporarily set for the FAX number. As a redirect response, a notification is sent to the sender facsimile machine 20 as the connection request source (P3). The transmission side facsimile apparatus 20 performs facsimile transmission or the like to a destination selected from the redirect destinations notified by the redirect response (P4).

  The receiving facsimile machine 30 has functions as a communication unit 31, a destination setting registration unit 32, and an IP telephone 33. The communication unit 31 functions to communicate with the SIP server 10 and other facsimile apparatuses via the network 2, and the destination setting registration unit 32 accepts a redirect destination setting operation from the user, or sets the destination information of the redirect destination (other device) The specific information) is transmitted to the SIP server 10 and registered. Here, a plurality of redirect destinations (specific information of other devices) can be set for one FAX number (identification information). Further, as the destination information of each redirect destination, in addition to the IP address (redirect address) of the redirect destination, the communication type of the redirect destination (accompanying information indicating whether it is a telephone or a facsimile machine) is set and registered.

  The SIP server 10 has functions as a communication unit 11 and a destination information storage unit 12. The communication unit 11 functions to communicate with the facsimile machines 20 and 30 through the network 2. For each FAX number, the destination information storage unit 12 stores information indicating whether or not the FAX number is being redirected. For FAX numbers that are not redirected, the FAX number and the facsimile machine of the FAX number are not included. Destination information associated with the IP address (specific information of the receiving facsimile machine 30) is stored. In addition, for the FAX number set for redirection, a plurality of pieces of destination information (specific information of other devices such as redirect destinations 40a to 40c) in which the FAX number, the IP address (redirect address) of the redirect destination and the communication type are associated with each other. Serves to store the redirect destination.

  When the redirect setting is made for the FAX number for which the connection request has been received, the SIP server 10 uses the destination information of all redirect destinations registered in association with the FAX number as a redirect response, and the facsimile of the connection request source. Return to the device.

  The transmission-side facsimile apparatus 20 functions as a communication unit 21, a communication information acquisition / setting unit 22, a transmission destination setting unit 23, a redirect destination selection unit 24, and a redirect destination list display unit 25. The communication unit 21 performs a function of communicating with the SIP server 10 and the other facsimile apparatuses 30 and 40a to 40c through the network 2, and the transmission destination setting unit 23 receives a setting of a destination (transmission destination) for facsimile transmission from the user. Fulfill. Here, the destination designation is received by the FAX number.

  The communication information acquisition / setting unit 22 creates, manages, and stores information to be transmitted to other devices and manages and stores information received from other devices when communicating with the other devices 10, 30, 40a to 40c. It fulfills functions such as When receiving a redirect response from the SIP server 10, the redirect destination list display unit 25 functions as a display unit that displays destination information (specific information of other devices) of a plurality of redirect destinations included in the redirect response. . The redirect destination selection unit 24 functions as a selection unit that selects any one or more redirect destinations from among a plurality of redirect destinations whose destination information is displayed on the redirect destination list display unit 25.

  The display contents of the redirect destination list display means 25 are controlled based on various attribute information included in the destination information. For example, only a plurality of redirect destinations indicated by the redirect response received from the SIP server 10 that are matched with a predetermined condition are extracted and displayed, or those that match the predetermined condition are displayed in different display formats. Or display.

  FIG. 2 shows a flow of processing when the receiving facsimile apparatus 30 performs redirect setting, and FIG. 3 shows an example of transition of an operation screen displayed on the operation display unit of the receiving facsimile apparatus 30 in the processing. ing. First, the destination facsimile apparatus 30 sets destination information related to a redirect destination (step S101). Specifically, at least one redirect destination is set by the user on the redirect destination setting screen 50 as shown in FIG. The user can set a plurality of redirect destinations.

  When the detailed setting button 51 is operated in a state where any one redirect destination is selected on the redirect destination setting screen 50, a detailed setting screen 53a shown in FIG. 3B is displayed. The user sets the IP address of the redirect destination in the destination input field 54 of the detailed setting screen 53a. Also, as attribute information related to the redirect destination, position information (transmission destination information) is set in the transmission destination information input field 55, a communication type is set in the number type input field 56, and a receivable time is set in the receivable time input field 57. Can be set. In the transmission destination information input field 55, information indicating where the receiver corresponding to the destination set in the destination input field 54 is installed is input. For example, enter your home, company name, etc.

  In the number type input column 56, the communication type of the receiver corresponding to the destination set in the destination input column 54 is input. For example, a facsimile apparatus with a telephone, or a telephone facsimile apparatus having both a facsimile function and a telephone function. Enter information such as In the receivable time input column 57, a time zone in which the user is likely to be near the receiver corresponding to the destination set in the destination input column 54 is input. These inputs may be directly input by the user from the operation display unit, or the number type may be selected from options prepared in advance. For example, when the change button 58 is pressed while the number type input field 56 is selected on the detail setting screen 53a, an option field 59 shown on the detail setting screen 53b in FIG. Select the communication type from the displayed information.

  When the setting related to the redirect destination is completed and the OK button 52 on the redirect destination setting screen 50 is pressed, the destination information related to the set redirect destination is transmitted to the SIP server 10 as a redirect setting request, and the destination information storage of the SIP server 10 is performed. Registered in the means 12 (step S102).

  FIG. 4 shows the flow of processing in the transmitting facsimile machine 20. When the FAX number of the transmission destination is designated by the transmission destination setting means 23 and the facsimile transmission start button (not shown) is operated in a state where the original is set in the scanner unit (not shown), the transmission side facsimile apparatus 20 is operated. An inquiry about the IP address corresponding to the FAX number of the transmission destination is made to the SIP server 10 (request for connection to the receiving facsimile machine 30 corresponding to the FAX number) (step S201, P2 in FIG. 1).

  Here, when the redirect setting is made for the FAX number of the transmission destination, a redirect response is received from the SIP server 10 as a response to the connection request (step S202, P3 in FIG. 1). The transmission side facsimile apparatus 20 displays a list of all redirect destination address information included in the redirect response received from the SIP server 10 on the redirect destination list display unit 25 (step S203).

  The user selects a desired destination from one or a plurality of redirect destinations displayed on the redirect destination list display means 25 with reference to destination information of each redirect destination (step S204). When the redirect destination is selected, the image information that should have been transmitted to the transmission destination initially designated by the transmission destination setting means 23 is transmitted to the selected redirect destination (step S205), and the processing is terminated (step S205). End).

  FIG. 5A is an example of a list display screen 70 for displaying destination information of all redirect destinations included in the redirect response. The list display screen 70 includes, for each redirect destination, a registration number 71, an IP address (redirect destination 72 in the figure), position information (transmission destination information 73 in the figure), and a communication type (type 74 in the figure). And the receivable time 75 are displayed in a horizontal row in association with each other. As shown in FIG. 5B, when the user presses a line 76 in which destination information of a desired redirect destination is displayed, the display color of that line is inverted and a selected state is entered. When the transmission button 77 is pressed in a state where one or more redirect destinations are selected, image information is transmitted by facsimile to the selected redirect destination.

  If there is no redirect destination to be transmitted, the transmission can be canceled by pressing the cancel button 78.

  As described above, when a plurality of redirect destinations are set for one FAX number, the display of the IP address alone determines where each redirect destination is and what device it is. Although it is difficult, attribute information such as transmission destination information, type, and receivable time is displayed, so that the user can select an optimum redirect destination with reference to these pieces of information.

Next, redirect destination mask processing will be described.
In FIG. 5, the destination information of all redirect destinations received from the SIP server 10 is displayed as a list. However, by performing the mask process shown in FIG. 6 in step S203 of FIG. Different redirect destinations can be displayed.

  In the mask process of FIG. 6, it is determined whether the transmitting facsimile machine 20 is attempting to perform facsimile transmission or making a telephone call, and the display contents are controlled according to the determination result.

  Specifically, the destination information of any one redirect destination is acquired from the plurality of redirect destinations received from the SIP server 10 (step S301). Next, it is determined whether or not the transmission side facsimile apparatus 20 is going to perform facsimile transmission (step S302), and if it is going to perform facsimile transmission (step S302; Y), the previously acquired redirect is performed. It is checked whether or not the communication type included in the destination address information is facsimile (may include a telephone) (step S303). If the communication type is not facsimile (step S303; N), the redirect destination is set as a mask target (shaded) (step S305). If the communication type is facsimile (step S303; Y), the redirect destination is not masked.

  On the other hand, when the transmission side facsimile apparatus 20 does not perform facsimile transmission (step S302; N), whether or not the communication type included in the destination information of the redirect destination acquired in step S301 is a telephone (or a facsimile with telephone). If it is not a telephone (step S304; N), the redirect destination is set as a mask target (step S305). If the communication type is a telephone (step S304; Y), the redirect destination is set. Is not masked.

  After performing the above mask determination, it is checked whether or not there are any redirect destinations for which mask determination has not been performed among a plurality of redirect destinations received from the SIP server 10 (step S306). Step S306; Y), the next redirect destination is acquired from among them (step S307), the process returns to step S301, and mask determination is executed for the redirect destination.

  For determining whether the transmitting-side facsimile apparatus 20 is about to perform facsimile transmission or to make a telephone call, the information set and input on the operation setting screen of the transmitting-side facsimile apparatus 20 may be used. The determination may be made using information on the job mode (for example, FAX mode) in the transmission side facsimile apparatus 20.

  When the mask determination is completed for all redirect destinations (step S306; N), a list of redirect destinations is displayed based on the data after the mask determination (step S308).

  FIG. 7 is an example of a list display screen 80 that displays a list of destination information of redirect destinations based on the data after mask processing. In this screen 80, the masked redirect destination is shaded. Further, this example is a case where the transmitting-side facsimile apparatus 20 is about to perform facsimile transmission, and the redirect destination of the communication type is set as a mask target and displayed by shading. On the other hand, a redirect destination whose communication type is facsimile (may be with a telephone) is not a mask target and is not shaded. The user cannot select a redirect destination that is masked (shaded) as a transmission destination, and can select a transmission destination only from redirect destinations that are not masked (shaded).

  In this way, the redirect destination that matches the initial communication purpose (facsimile transmission or telephone) and the redirect destination that does not match are identified and displayed, and the redirect destination that does not match cannot be selected as the transmission destination, so that the facsimile transmission can be performed. It is possible to prevent execution to a telephone redirect destination.

  FIG. 8A is an example of a list display screen 90a in which only redirect destinations that are not mask targets are extracted and displayed. FIG. 8B is a sort based on the receivable time (FIG. 8A). It is an example of the list display screen 90b when the (sorting) process is performed. In FIG. 8A, redirect destinations whose communication type is telephone are excluded from display targets, and only redirect destinations whose communication type is facsimile are extracted and displayed in a list. In this way, only the redirect destinations that match the initial communication purpose (facsimile transmission) are displayed on the list display screen 90a, so that the user recognizes whether or not the selection is possible based on the presence or absence of shading as shown in FIG. This eliminates the need for the transmission destination selection and selection operation by the user.

  In FIG. 8B, the current time is compared with the receivable time of each redirect destination, and the redirect destination corresponding to the receivable time for which the current time is set is displayed with the highest priority (displayed at the top of the list). ing. Among redirect destinations that do not have a current time within the receivable time, those with a current time close to the receivable time are displayed with higher priority. In the example of FIG. 8B, since the current time is “7:30”, the redirect destination (company B) 91 whose receivable time is “7:00 to 12:00” is at the top of the list. No. 001 is displayed. Further, the redirect destination (company A) 92 whose receivable time is “24:00 to 7:00” has a difference of 30 minutes from the current time, and the receivable time “20:00 to 24:00”. The redirect destination (home) 93 that is “” has a difference of 7 hours and 30 minutes from the current time, so the former 92 with a small time difference is displayed higher than the latter 93.

  In this way, redirect destinations that are likely to be nearby are preferentially displayed at the top of the list, so that the user can easily select an appropriate redirect destination.

  In addition, it may be configured to automatically transmit to a redirect destination whose current time is within the receivable time regardless of whether or not the user has selected.

  The embodiment of the present invention has been described with reference to the drawings. However, the specific configuration is not limited to that shown in the embodiment, and there are changes and additions within the scope of the present invention. Are also included in the present invention.

  For example, in facsimile transmission, when the user operates the send button without selecting any redirect destination, the following operations [1] to [3] can be performed.

[1] Transmit to all redirect destinations whose communication type is facsimile among the redirect destinations received in the redirect response.

[2] The current time is compared with the receivable time of the redirect destination for each redirect destination whose communication type is facsimile among the redirect destinations received by the redirect response, and the current time is within the receivable time. If there is a redirect destination, it is automatically sent to that redirect destination. If there is no redirect destination that has the current time within the receivable time, the registration number is the highest among the redirect destinations whose communication type is facsimile. Send to an early redirect destination.

[3] Among the redirect destinations received by the redirect response, the registration number having the communication type of facsimile is transmitted to the redirect destination with the earliest.

  Here, the registration number may be the order after sorting by the receivable time or the like, or may be the order in which the registration time in the SIP server 10 is early, or may be set according to an appropriate standard. By variously using the attribute information of the redirect destination, it is possible to automatically select the redirect destination in the transmission side facsimile apparatus 20 without waiting for the user's selection.

  In addition, in the embodiment, the location information, the communication type, and the receivable time are exemplified as the redirect destination attribute information. However, any other attribute items may be used as long as they can serve as an index for selecting the redirect destination. . For example, it may be redirect destination capability (maximum paper size, etc.). Moreover, although the home, the company, etc. were illustrated as position information, the floor, department, branch name, etc. in a company may be sufficient. In the communication type, for example, when there are a plurality of transmission forms as network facsimiles (compliant with ITU-T T.37, T.38, etc.), they may be distinguished.

  In the embodiment, the sort process is performed based on the receivable time. However, the sort process may be performed based on other attribute items, or a plurality of items to be used as the sorting reference may be set. For example, when there are a plurality of redirect destinations that are first sorted by the receivable time and the current time is within the receivable time, they are further set as the second reference (for example, the destination information is a company that is a home. You may sort and display by criteria).
