Abstract

PROBLEM TO BE SOLVED: To enable effective selection based on the communication ability at a transfer destination by selecting either a first transfer means for instructing transfer to an ISDN or a second transfer means for temporarily receiving data from the transmission source and then transmitting them based on the result of comparison between attribute data related to a party's telephone number matched with the call originating number of the transmission source and attribute data at the transfer destination. SOLUTION: The velocity consistency data of opposite equipment or the communication ability data such as G4/G3 are stored in a party's telephone number storage area. When a call is terminated, it is collated whether a caller number is matched with the stored party's telephone number or not. When they are matched, it is judged while referring to the attribute data related to the party, whether the transmission source is G4 or G3. When the transmission source is G4, 'incoming call transfer for each call' is selected as a transfer system. In the case of G3, it is judged while referring to the attribute data related to the destination to transfer, whether the transfer destination is G4 or G3, and when the destination is G4, 'transfer after call incoming' is selected, but in the case of G3, 'incoming call transfer for each call' is selected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a data communication apparatus such as a facsimile apparatus connectable to an ISDN.

[0002]

2. Description of the Related Art With the spread of ISDN in recent years, IT
In the U-T, standardization of a facsimile apparatus having a call transfer function provided by ISDN is being studied.

There are various types of call forwarding functions provided by the ISDN. Among them, each time a call to the telephone number of the own terminal is made, a call forwarding method (call-first call forwarding method) capable of forwarding a call according to the callee's will. 1 transfer means) is known.

There is also known a method (second transfer means) of receiving a call after identifying the other party using a caller number included in SETUP information at the time of an incoming call.

[0005] Then, by using such additional services in combination, a caller ID is registered in advance,
There is provided a facsimile apparatus having a function of performing transfer only when a calling number notified from a network matches a registered number, or performing transfer by changing a transfer destination for each calling number.

[0006]

However, in the above-described conventional example, when the state of the apparatus is shifted to the transfer mode by a user's operation or the like, the incoming call after that is included in the SETUP information at the time of the incoming call. If the caller ID matches the registered caller ID, the transfer is automatically instructed to the network. For example, when the transmission source is G3 facsimile and the transfer destination is G4 facsimile, the transmission from the transmission source is performed. When the transfer is instructed to the network in response to the incoming call, even if the transfer destination facsimile has the G4 communication capability, the source facsimile does not have the G4 communication capability, so that the original is transmitted by the G3 protocol.

In other words, the transmission time is longer due to transmission using the G3 protocol, which requires more time than G4, and the communication is charged in proportion to the transmission time. There was a problem that it would.

Accordingly, it is an object of the present invention to provide a data communication apparatus capable of effectively selecting a call transfer method based on the communication capability of a transfer destination and performing efficient call transfer using ISDN. .

[0009]

According to the present invention, there is provided a memory dial storing means for storing a destination telephone number in a memory dial, and a communication capability registering means for registering a communication capability of a destination communication device in association with the destination telephone number. Transfer destination telephone number storage means for storing a transfer destination telephone number; attribute data storage means for storing attribute data of a transfer destination communication device in association with the transfer destination telephone number; and instructing transfer to an ISDN network. A first transfer unit, a second transfer unit that once receives data from a transmission source, and transmits the data to a destination again.
Compare the attribute data of the destination communication device with the attribute data of the destination communication device associated with the destination telephone number that matches the calling number of the source communication device, and based on the comparison result,
By having the selection means for selecting the first transfer means and the second transfer means, communication can be performed with appropriate communication capability, communication time can be reduced, and communication charges can be reduced.

At the time of an incoming call, the attribute data of the destination communication device and the attribute data of the transfer destination communication device associated with the destination telephone number that matches the calling number of the source communication device are compared, and based on the result of the comparison. The first transfer method and the second
To select the transfer method. Hereinafter, the operation of the present embodiment will be described.

FIG. 2 is a flowchart showing the incoming call transfer processing of the facsimile apparatus in the present embodiment.

In this embodiment, when there is an incoming call request from the network in S201, a process of selecting a transfer operation is performed in S202. The selection here is a first transfer method for instructing the network to transfer to a desired transfer destination telephone number, a second transfer method for transmitting image data to the transfer destination telephone number once after receiving an incoming call, and not transferring. , Is automatically selected. Details of the processing here will be described later.

When "call transfer per call" is selected in S203 based on the selection process, a transfer instruction is issued to the network in S204. This is the first transfer method. In the transfer instruction, notification of the telephone number information of the transfer destination registered in advance by the user is also performed.

When "transfer after incoming call" is selected in S203, an incoming call is received in S205 and a transmission message is received. After the reception is completed, a call is made to the transfer destination telephone number in S206, and the transmission message is transmitted. This is the second transfer method. S2
If it is determined in S03 that transfer is not to be performed, an incoming call is made in S207, and the process ends.

FIG. 3 is a flowchart showing the above-described transfer method selection processing.

In this embodiment, not only the telephone number but also the speed consistency data for the inter-network connection of the facsimile machine is stored in the area for storing the destination telephone number as the destination of the one-touch / abbreviated dialing of the facsimile machine. And G
4 or G3 is stored in association with the communication capability data. This is attribute data.

When there is an incoming call, the facsimile apparatus returns to S3.
At 01, it is checked whether the caller number included in the SETUP information matches the stored destination telephone number.

As a result of this collation, if there is a matching destination telephone number in S302, the attribute data associated with the destination telephone number is referred to in S303.

Based on the attribute data referred to, S3
04, the communication capability of the source facsimile is "G4" or "G
3 ". If the transmission source facsimile has the communication capability of "G4" as a result of the determination, in step S305, "call transfer per call" is selected as the transfer method.

If it is determined in step S304 that the communication capability of the source facsimile is "G3",
In S306, the attribute data associated with the transfer destination telephone number is referred to.

Then, based on the referenced attribute data, the communication capability of the destination facsimile is set to "G" in S307.
4 ”or“ G3 ”. If it is determined that the transfer destination facsimile has the communication capability of “G4”, “transfer after incoming call” is selected as the transfer method in S308.

If it is determined in step S307 that the communication capability of the transfer destination facsimile is "G3", the flow advances to step S305 to select "call transfer per call" as the transfer method.

If the result of the collation in S302 shows that the caller number included in the SETUP information does not match the stored destination telephone number, "transfer by call" or "transfer after call" is selected as the transfer method. If this happens, unnecessary direct mail or the like will be transferred, and there will be problems such as being charged.

Therefore, in the facsimile apparatus of this embodiment, when a transfer method is selected to solve these problems, it is determined in advance by the user whether or not to transfer an incoming call whose caller number is unknown. Has a function that can be set.

First, in S309, according to the setting of whether or not to transfer when the caller number is unknown, if it is determined not to transfer, "not transfer" is selected as the transfer method in S310. On the other hand, when the transfer is performed in S310, the process proceeds to the node 1 (S305).

As described with reference to FIG. 3, the communication capability of the transmission source facsimile needs to be registered in advance as attribute data when the user registers the destination telephone number. In some cases, such as when a terminal is replaced, a terminal having a different communication capability is changed. In consideration of such a situation, as a means for determining the communication capability of the transmission source facsimile without depending on the registered attribute data, a configuration using a bearer service or a teleservice provided by ISDN is also possible.

In step S404, it is determined whether the communication capability of the transmission source facsimile is “G4” or “G3” based on the referenced attribute data.

If it is determined that the source facsimile has the communication capability of "G4", in step S405, the information notified by the service provided by the network is referred to. Determine whether it is G4 facsimile or not.

If it is determined that the transmission source is a G4 facsimile, the flow advances to S407 to select "call transfer".

If it is determined in S406 that the source terminal is other than G4 facsimile, the node 3 (S
Proceed to 410).

If it is determined in step S404 that the communication capability of the source facsimile is "G3", information notified by a service provided by the network is referred to in step S408. Terminal is G4 facsimile or not.

In the case of G4 facsimile, S4
07, but if it is other than G4 facsimile, S41
0 refers to the attribute data associated with the transfer destination telephone number. Then, based on the referenced attribute data,
In step S411, it is determined whether the communication capability of the destination facsimile is “G4” or “G3”.

As a result of the judgment, if the destination facsimile has the communication capability of "G4" in S411,
Select "Transfer after incoming call" as the transfer method. Also, S4
If it is determined in step 11 that the communication capability of the destination facsimile machine is "G3", the flow advances to step S407 to select "call-by-call transfer" as the transfer method.

Also, as a result of the collation in S402,
If the caller number included in the P information does not match the stored destination telephone number, the process proceeds to S413. here,
Since the user has a function to set in advance whether or not to transfer an incoming call whose caller number is unknown, this S413
, Refer to the setting of whether or not to transfer when the caller ID is unknown. If it is determined that the transfer is not performed, S414
"Transfer method" is selected as the transfer method. On the other hand, S4
When the transfer is performed at step 13, the process proceeds to node 2 (S405).
