Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention has a relay function, and the content of the information table of the international prefix number and country code set of the international gateway stored in advance and the information of the relay requesting station are provided. The present invention relates to a facsimile relay device that generates the number of a relay receiving station as seen from its own terminal by referring to the international prefix number and country code of the relay receiving station specified by the facsimile relay device.

[Prior Art] Conventionally, facsimile machines with a relay function have been put into practical use.

In this relay function, a relay requesting station transmits image information to be relayed and destination information specifying a relay receiving station to a relay station, and the relay station stores the received information and receives the specified relay station. The system calls the relay receiving station and transmits the accumulated image information to the relay receiving station.

At this time, the relay requesting station transmits the destination number as seen from its own terminal.
In order to notify as destination information specifying the relay receiving station,
The relay station needs to convert the received destination information into a telephone number seen from its own terminal.

For example, consider a network spanning countries A and B as shown in FIG.

In the figure, country A has two domestic networks DAI, DA2 and 1.
Two international gateways IGI have been constructed, and a facsimile terminal FXL is connected to the domestic network DAI, and a facsimile terminal FX2 is connected to the domestic network DA2.

In addition, one domestic network DB and one international gateway IG3 have been constructed in country B, and the domestic network DB has two facsimile terminals FX3. FX4 is connected.

The international gateway IGI and the international gateway IG3 are interconnected, and the facsimile terminals FXI, FX2 and facsimile terminals FX3. FX4 can call a facsimile terminal connected to the domestic network of the destination country by adding an international prefix number (international gateway access identifier) that calls the international gateways IGI and IG3 to the destination's international telephone number. can.

Now, for example, facsimile terminal FXI (relay request station)
When a request is made to facsimile terminal FX3 (relay station) to relay to facsimile terminal FX4 (relay receiving station), facsimile terminal FXI
3 and transmits the image information, and at the same time, the telephone number of the relay receiving station is notified by adding the international prefix number of the international gateway IG3 to the international telephone number of the facsimile terminal FX3. In addition, as for the phone number of the own terminal, international gateway 1G1 is added to the international telephone number of the own terminal.
will be notified with the international prefix number added.

The relay station accumulates received image information, stores the telephone numbers of the relay receiving station and the relay requesting station, and converts these telephone numbers into telephone numbers seen from its own terminal.

At this time, when converting the telephone number of the relay receiving station,
Since the telephone number has the country code and international prefix number appended to the domestic number, the relay station removes the country code and international prefix number from the telephone number, and
A domestic number is extracted and a call is made to the relay receiving station using the domestic number.

Also, when notifying the relay requesting station of the relay result, the international prefix number is removed from the relay requesting station's phone number, and
A telephone number is created by adding the international brief exchange number of the international gateway IG3 accessed by the own terminal, a call is made to the relay requesting station using the telephone number, and an image of the relay result report is transmitted.

In order to be able to convert the telephone number of a relay receiving station or relay requesting station to the number seen from the terminal itself, conventionally, data consisting of a pair of international prefix number and country code was registered on each facsimile terminal. This allows appropriate number conversion during relay processing. Also,
The contents of this registered data are known at the time of manufacturing the facsimile machine, and conventionally are stored in a fixed storage device such as a ROM (read-only memory).

[Problems to be Solved by the Invention] However, such conventional devices have the following disadvantages.

That is, in FIG. 5, if a new international gateway IG4 is constructed in country B and the facsimile machine FX4 changes its line to use this international gateway IG4, the facsimile machine FX4 will In order to use the international prefix number, for this international gateway IG4, unless the international prefix number and country code set data is registered in each facsimile machine FXI, FX2, and FX3, the phone number conversion process at the time of relay cannot be performed properly. In such a case, the relay function could not be applied.

Here, the international prefix number is the other phone number,
That is, unlike the country code, network identification number, and subscriber number, its format is set based on national regulations.

Regarding the country code, network identification number, and subscriber number, in accordance with the recommendations of CCITT, the country code is set to a unique value, and the other numbers are set to a format common to each country.

For this reason, it is not possible for each terminal to automatically determine the international prefix number to be assigned to a newly constructed international gateway, and it is necessary to register it in the device as in the conventional device described above.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a facsimile apparatus that can appropriately apply an international relay function.

[Means for Solving the Problems] The present invention includes a rewritable storage device that stores an information table, and a registration device that adds items to the information table stored in the storage device. Moreover, this registration means prevents the content of the registration operation from being additionally registered if the set of international prefix number and country code that has been registered has already been registered in the storage device.

[Operation] Therefore, since the set of the international briefing number and country code of the newly constructed international gateway can be registered as appropriate, the international relay function can be appropriately performed. Furthermore, if the registered content has already been registered, that content will not be additionally registered, so that inconveniences such as double registration can be prevented.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In this way, when a new international gateway is constructed, its international briefing number IP and country code CC can be input as appropriate, so that telephone number determination at the time of relay can be appropriately performed.

FIG. 4 shows an example of a telephone number shaping process executed when forming a telephone number of a relay receiving station during relay.

When making a relay request, the relay requesting station sends the relay image information to the relay station, the relay receiving station's international telephone number (including the international prefix number of its own terminal) as seen from the relay requesting station; hereinafter referred to as the relay receiving station. The relay requesting station number) and the international telephone number of the relay requesting station (including the international prefix number of the own terminal; hereinafter referred to as the relaying requesting station number) are transmitted.

The relay station stores the received image information, the international phone number of the relay receiving station, and the international phone number of the relay requesting station, selects one specified relay receiving station, and calls that relay receiving station. Execute this process before

First, refer to the contents of the international prefix number table to extract the international prefix number IP and country code cc included in the own terminal telephone number information, and then The country code CC5, that is, the country code CCa of the own terminal telephone number is extracted from (process 2o1).

Next, with reference to the contents of the international prefix number table, the set of international prefix number IP and country code CC included in the relay request station number notified from the relay request station is extracted, and the extracted international prefix number is The country code CC5, that is, the country code CCb included in the relay request station number is extracted from the set of the number IP and the country code cc (processing 2o2).

Then, compare the two country codes CCa and CCb,
It is checked whether the relay requesting station is installed in the same country (determination 203).

Next, refer to the contents of the international brief ex number table,
By processing similar to the above, the country code CCc included in the target relay receiving station number is extracted, and the country code C
Cc is compared with the country code ccb of the relay requesting station to check whether the call to the relay receiving station is an international call from the perspective of the relay requesting station (determination 204).

When the result of judgment 204 is YES, since the call is an international call from the same country as the relay station, the received relay reception number is used as is as the destination telephone number (process 205).
.

Also, when the result of judgment 204 is NO, it is because the relay receiving station is installed in the same country as the relay station.
The international prefix number IP and country code CC are removed from the relay reception number to format it into a domestic number, and the domestic number is used as the destination telephone number (process 206). At this time, if necessary, enter the long-distance prefix number (in Japan,
"0") is added.

When the result of judgment 203 is NO, the same process as above is used to extract the country code CCc included in the target relay receiving station number, and compare the country code CCc with the country code ccb of the relay requesting station. The relay requesting station then checks whether the call to the relay receiving station is an international call (determination 207).

When the result of judgment 207 is YES, the country code CCc of the relay receiving station is compared with the country code CCa to check whether the relay receiving station is installed in the same country as the relay station (
Judgment 208).

When the result of judgment 208 is YES, the international prefix number IP and country code CC are removed from the relay reception number, the number is formatted into a domestic number, and the domestic number is used as the destination telephone number (process 209).

When the result of judgment 208 is No, the international prefix number IP of the relay station is added to the relay receiving station number by removing the international prefix number IP, and the relay receiving station number is formatted into an international number as seen from the own terminal. and uses that international number as the destination telephone number (process 210).

When the result of judgment 207 is NO, the international prefix number IP of the relay station is added to the relay receiving station number by removing the international prefix number IP, and the relay receiving station number is formatted into an international number related to the own terminal. Then, the international number is used as the destination telephone number (process 211).

In this way, by converting the relay receiving station number notified from the relay requesting station into the telephone number seen from the own terminal, an appropriate calling operation can be performed.

Furthermore, when transmitting a relay result report to a relay requesting station, the relay requesting station number is converted to a telephone number seen from the own terminal in the same manner as described above.

As described above, in this embodiment, the contents of the international prefix number table used in the telephone number formatting process of the relay receiving station and the relay requesting station can always be updated, so that the telephone number formatting process can be performed appropriately. It can be carried out.

By the way, in the embodiment described above, the international prefix number and country code are manually input from the operation display section.
