DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention provides services such as connection to an absence guidance device and call forwarding that are executed when a called user is absent or out of service area (in the case of a mobile body). Subscribers).

[0007] That is, the calling user rejects services such as connection to the absence guide device and call forwarding by dialing with a special number added before the telephone number of the called user (the party to call). (Busy Tone (Bus
y Tone)) and talkies (voice guidance such as out-of-service talkies).

FIG. 1 shows a configuration example of an embodiment of a communication network system to which the present invention is applied. The telephones 1 and 5 are fixed telephones (including facsimile (FAX)),
The telephones 2 and 6 are mobile phones such as mobile phones. However, the telephones 1 and 2 are telephones used by the calling subscriber, and the telephones 5 and 6 are telephones used by the called subscriber.

The originating network 3 and the terminating network 4 each include an exchange, and the exchanges of the terminating network 4 can access the absence guidance device 7. The absence guidance device 7 records a message from the subscriber of the transmission source (telephone 1, 2) when the destination (telephone 5, 6) subscriber is absent or the telephone 5, 6 is out of service area. It is a device to do.

FIG. 2 shows, in the present embodiment, for example,
The calling subscriber uses the telephone 1 to give the telephone number of the telephone 5 used by the called subscriber a special number indicating that connection to the absence guidance device 7 and rejection of call forwarding will be refused. 9 is a flowchart showing an operation from dialing, actually connecting to the absence guide device 7 and rejecting call forwarding.

Hereinafter, the operation of the present embodiment will be described in detail with reference to FIG. 1 and FIG. In this case, the calling subscriber uses the telephone 1 and uses the telephone 5 of the called subscriber.
The operation in the case of making a call to is described.

First, the calling subscriber uses the telephone 1 to send a special number to the destination subscriber's telephone 5 for rejecting the connection to the absence guide device 7 and the transfer of the incoming call. The telephone number is added to the head of the telephone number and dialed, and the dialed telephone number is transmitted (step A1 in FIG. 2).

The exchange of the originating network 3 is such that the originating subscriber is
In order to determine whether connection to the absence guidance device 7 or call transfer is desired, the dialed telephone number is
It is checked whether a special number indicating that the absence connection and the call transfer are rejected is given.

Based on the result of the check, information indicating whether or not a special number indicating that the absence guidance connection and the call transfer are rejected is added to the additional information. While transmitting, the call from the source is transferred to the receiving network 4. The exchange of the terminating network 4 terminates the call from the source to the telephone 5 of the destination subscriber.
(Step A2 in FIG. 2).

Next, the exchange of the receiving network 4 determines whether or not there is a response from the telephone 5 of the called subscriber (step A3 in FIG. 2). The response from the telephone 5 is transmitted to the receiving network 4 via the telephone line.

If there is a response from the telephone 5 of the called party (Yes in step A3), the processing is terminated.

On the other hand, if there is no response from the telephone 5 of the called subscriber (No in step A3), it is determined whether the connection of the calling subscriber to the absence guide device 7 and the possibility of forwarding the call are determined. (Step A4 in FIG. 2). That is, it is determined whether or not the destination subscriber has set the telephone 5 to perform the absence guidance connection or the call forwarding.

As a result of the determination, the destination subscriber does not set the telephone 5 to perform the absence guidance connection or the call forwarding, and the telephone 5
If the connection to the telephone or the call transfer is not permitted (No in step A4), the exchange of the terminating network 4 continues to call the telephone 5 until the telephone 1 disconnects the call (step A5).

On the other hand, as a result of the determination, the destination subscriber is set to perform the absence guidance connection or the call forwarding to the telephone 5, and the telephone 5 is connected to the absence guidance device 7, Or, if call forwarding is permitted (step A
4), the exchange of the terminating network 4, based on the additional information set by the exchange of the originating network 3, connects the missed call connection and call forwarding to the telephone number transmitted by dialing the telephone 1 by the calling subscriber. It is determined whether or not a special number indicating that the request is rejected is given (step A6 in FIG. 2).

As a result of the determination, a special number for rejecting connection to the absence guidance device 7 and call transfer is given.
In other words, if it is determined that the calling subscriber has indicated that he / she wants the absence notification connection and call forwarding not to be performed (No in step A6), BT (Busy Tone) Or a connection to a talkie (out of service talkie) is made (step A7).

On the other hand, as a result of the determination, a special number for rejecting connection to the absence guidance device 7 and call transfer is not given.
That is, when it is determined that the calling subscriber has indicated that the absence guidance connection and the call forwarding may be performed (Yes in step A6), the absence subscriber performs the absence guidance. When the call is forwarded, the call is transferred to the transfer destination telephone set as the call transfer destination. To
(Step A8). When the connection to the absence guide device 7 is established, the calling subscriber can record and store a message for the called subscriber.

As described above, the absence guidance connection, the ISDN
(Integrated services digi
A call transfer service, which is a typical service of a tal network, can be regulated by the subscriber (caller) of the caller. Therefore, it is possible to prevent the out-of-office connection or the transfer of the incoming call from being executed at the will of the caller, so that unnecessary billing can be prevented. In addition, the information of the caller can be protected without the caller's caller being notified of the caller's calling number.

Also, when the telephone is a facsimile, the call transfer service is regulated similarly to the case of the telephone,
Unintended operation of the caller can be prevented.

Further, as described above with reference to FIG. 2, the same special number is used for rejection of the absence guidance connection and rejection of the call transfer service, and the special number is appropriately replaced with the telephone number according to the will of the caller. Not only rejects or allows both the missed call connection and call forwarding service, but also separates the special code for rejecting the missed call connection and the special code for rejecting the call forwarding service. Depending on the caller's will, one of the special numbers can be added to the telephone number to selectively reject only one of the missed call connection and the call forwarding service. .

The case where a call is made from the telephone set 1 to the telephone set 5 has been described above. The case where a call is made to the telephone set 6 which is a mobile telephone is the same as that described above with reference to FIG. Is performed. However, in that case, the call from the terminating network 4 is transferred to the telephone 6 via the base station 9. Further, the response from the telephone 6 is transmitted to the exchange of the terminating network 4 via the base station 9.

When a call is made from the mobile telephone 2 to the fixed telephone 5 or the mobile telephone 6, the same processing as described above with reference to FIG. Is performed. However, in this case, the call from the telephone 2 is transmitted to the transmission network 3 via the base station 8.

As described above, according to the present embodiment, the following effects can be obtained. In other words, since the caller's will can reject the absence guidance and call forwarding, the telephone line (call path) is not connected to the absence guidance device or the transfer destination telephone contrary to the will. Unnecessary charges can be prevented from being generated.

Further, it is possible to prevent the originating subscriber from being connected to the absence guidance device when he / she does not intend to register the answering machine message.

Further, by using the special number, this function can be used in an existing terminal.

The configuration of the above embodiment is an example, and the number of telephones and the number of transmission networks are not limited to the above embodiment.

Further, in the above-described embodiment, a case has been described where the rejection of the absence guidance connection and the rejection of the call transfer service are controlled by the caller's will. However, the present invention is not limited to this. The present invention can also be applied to the case where the denial of service is controlled by the sender.

[0032]

As described above, according to the communication network control method and the communication network system according to the present invention, the exchange sets the telephone number dialed by the calling telephone to the telephone number of the called telephone. Judge whether the special number is added, judge whether or not the call from the calling side has answered the call from the called side. It is determined whether or not it is set to perform a predetermined service for the telephone of the called side, and it is determined that the predetermined service is set to be performed for an incoming call to the called side, When it is determined that the telephone number dialed by the calling telephone is a telephone number of the called telephone with a predetermined special number added, the service is provided to the calling telephone. Since so as to control the strange,
Using an existing terminal, services such as an absence connection and a call transfer can be easily performed based on the intention of the caller.
