Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention sets up a call prior to the start of communication, and transmits user / user information between communication devices connected to a network when setting up the call. The present invention relates to a communication method in an ISDN network having a function and a communication device connectable to the ISDN network.

[Prior Art] Conventionally, after a call is established even for malicious calls such as telephone mischief, harassment, and facsimile mischief transmission,
Whether the other party is a malicious call or not is determined by confirming with a voice or determining an ID signal transmitted by a machine. Although different from the technical solution, some people take measures such as not disclosing a telephone number to avoid malicious calls.

[Problem to be Solved by the Invention] However, in the above-described conventional example, since a malicious call is determined after a call has been established, there is a disadvantage that the determination is performed after the receiver is once called. Furthermore, several steps of communication, such as waiting for a response from the other communication device to establish a call, must be performed. Even if the call is not a valid call, the inconvenience of occupying network resources for this call exists. did. Also, in the method of not disclosing the telephone number, since communication can be established by a normal operation for making a telephone call, malicious calls cannot be excluded due to accidental control.

The present invention has been made in view of the above problems,
A person who does not know the identification information of the called communication device by using user user information that can be transmitted between the calling communication device and the called communication device without providing the switching device with a special function. The purpose of the present invention is to allow an incoming call from a user to be rejected before a call is established, and, in the case of rejecting an incoming call, to transmit information according to the progress up to the incoming call rejection to the calling communication device. And

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a communication method in an ISDN network having a function of transmitting user user information between communication devices connected to the network when setting up a call. The calling communication device transmits address information specifying the called communication device and identification information of the called communication device using the user information, and the called communication device specified by the address information Determining whether the identification information included in the received user information corresponds to the identification information of the called communication device that is arbitrarily set and stored, and determines whether the received identification information is If it is determined that the stored identification information does not correspond to the stored identification information, the received identification information does not correspond to the stored identification information. ,Previous User transmits to the calling communication device using user information, and when it is determined that the received identification information corresponds to the stored identification information, the calling of the called communication device is performed. The call information transmitted to the calling communication device is transmitted to the network, and an operator is called. When the operator responds to the call of the operator, a communication state is set. If there is no response to the call of the operator despite notifying that the call of the calling communication device has been made, it indicates that the incoming call is rejected because there is no response of the operator to the call.
And transmitting the information to the calling communication device using the user information.

Also, in a communication method in an ISDN network having a function of transmitting user user information between communication devices connected to the network at the time of call setting, a called communication device designated by address information transmitted by a calling communication device. However, upon receiving the identification information transmitted by the calling communication device using the user user information, the received identification information, and the identification information of the called communication device is set and stored arbitrarily If the received identification information and the stored identification information do not correspond to each other, it is determined whether or not the received identification information corresponds to the stored identification information. First information indicating that the incoming call is rejected for not being transmitted is transmitted to the calling communication device using the user information, and the received identification information corresponds to the stored identification information. When it is determined that the calling communication device is called, the calling communication device notifies the calling communication device of calling information to the network and calls an operator. When a response is made, the communication state is set, and although the calling communication device is notified of the call of the called communication device, if there is no response to the call of the operator, the response of the operator to the call is returned. And transmitting, to the calling communication device, second information indicating that the incoming call is rejected because there is no call, using the user information.

Further, in a communication device connectable to an ISDN network having a function of transmitting user user information between communication devices connected to the network at the time of call setting, storage means for storing identification information arbitrarily set in the communication device And receiving means for receiving identification information transmitted by the calling communication device using the user user information, and identification information received by the receiving means,
Determining means for determining whether the stored identification information corresponds to the stored identification information of the communication device; and determining that the received identification information corresponds to the stored identification information by the determination means. Calling means for notifying the calling communication apparatus of calling the called communication apparatus to the calling communication apparatus to the network and calling an operator; and calling the operator by the calling means, Setting means for setting a communication state when an operator responds, and when it is determined that the received identification information does not correspond to the stored identification information, the received identification information and the stored identification information are stored. The first user information is transmitted to the calling communication device by using the user information, and the first information indicating that the incoming call is rejected because the call does not correspond to If there is no response to the call of the operator despite notifying the call of the side communication device, second information indicating that the incoming call is rejected because there is no response of the operator to the call is displayed in the user user information. And control means for controlling transmission to the calling communication device by using the communication device.

Here, if the identification information from the calling communication device is not received, third information indicating that the incoming call is rejected because the identification information is not received is transmitted using the user user information. To the local communication device.

[Operation] According to the present invention, an incoming call from a person who does not know the identification information of the called communication device can be rejected before the call is established, without providing the switching device with a special function. For example, it is possible to prevent a wrong call or a mischievous call from a person who does not know the identification information of the called communication device before setting up a call, and when rejecting an incoming call, the process until the call is rejected. Since the corresponding information can be transmitted to the calling communication device, if the operator does not answer the call despite notifying the calling communication device of the call of the called communication device, there is no response from the operator. Information indicating that the incoming call is rejected can be transmitted to the calling communication device, and if the identification information transmitted by the calling communication device does not correspond to the stored identification information, the received identification information is Corresponds to stored identification information Information indicating that the incoming call is rejected because the call is not received can be transmitted to the calling communication device. Further, when the identification information from the calling communication device is not received, information indicating that the incoming call is rejected because the identification information is not received can be transmitted to the calling communication device.

In this system, the first
The communication terminal 8 shown in FIG. 2 is used as the terminals 10 and 13. FIG. 4 (A) and FIG. 4 (A) show a protocol for executing a communication method for selective reception used between these two terminals.
It is shown in FIG. According to the present embodiment, the functions provided in the network transmitted end-to-end and transparent between the terminals prior to setting up a call between the terminals include, for example, a network relating to the INS network service. The "user-user" information element conveyed at the time of the supported call setup corresponds to this. The communication method of the present invention is not limited to the "user / user" information element of the present embodiment, but is transmitted to the end-to-end and transparent between terminals before setting up a call as a network. Any function can be used as long as the function is provided.

FIGS. 4 (A) and 4 (B) show the operation and replacement procedure of each node in the system of FIG. First, a normal line connection procedure will be described with reference to FIG. When the originating terminal 10 is off-hook and a call is set to the originating exchange 11 (20), the originating exchange 11
Returns the call setting acceptance to the originating terminal 10 (21) and transmits the call to the terminating exchange 12 so that the terminating exchange 12
Call setting is performed for (22). Once the call setup is made,
Perform normal phone line connection procedures. That is, the called terminal 13 makes a ringing tone, and this call is made to the called exchange.

On the other hand, as shown in FIG. 4 (B), when a malicious call is determined in the call setup, the receiving terminal 13 requests a line disconnection (2
8), the receiving side exchange 12 releases the receiving side terminal 13. At the same time, the originating exchange 11 disconnects the originating terminal (29) and ends the call.

FIG. 5 shows the format of the message shown in FIGS. 4 (A) and 4 (B). Among the information contents in FIG. 5, only the "user / user" information element is transmitted between terminals in a transparent manner.

FIG. 6 (A) is a flowchart showing the operation of the user at the transmitting terminal, FIG. 6 (B) is a flowchart showing the operation of the transmitting terminal 10 in FIG. 3, and FIG. A flowchart showing the operation of the called terminal 13 in the figure is shown, and the operation of the present embodiment will be described accordingly.

In FIG. 6 (A), first, the calling user 9 shown in FIG. 3 turns off the handset of the terminal 10 (S10).
Thereafter, it is determined whether the ID needs to be pressed (S11).
If necessary, the user presses the ID key (S12), and then dials the other party's telephone number (S13). The terminal 10 does not operate on the network when the telephone number is dialed.
After dialing the telephone number of the other party, the user 9 presses the ID key again (S14), and then the ID of the called terminal to be communicated with.
Is input (S15). Finally, by pressing the ID key again (S16), the terminal 10 sends a call setup message shown in FIG. 4 to the network. As shown in FIG. 5, the other party's telephone number is inserted in the term of the called number in the column of call setting 20, and the other party's terminal
The ID is inserted in the User section.

In this communication device terminal, in the case of normal telephone communication that does not require an ID, dialing the other party's telephone number without pressing the ID key (S17) and pressing the # key (S18)
This establishes a call.

Note that the ID is a transparent user information element, so any ID can be used as long as it is a code that can be collated instead of a number, and is an item arbitrarily determined between devices. or,
It is obvious that the ID does not have to be one for one terminal, and various applications are conceivable. The above-mentioned operation is only an example, and it is conceivable to use the * and # keys and other keys to separate the telephone number ID number input.

As shown in FIG. 6 (B), the transmitting side terminal 10 is connected to the terminal shown in FIG. 6 (A).
ID in user / user information element corresponding to user's operation
It is determined whether or not a number is to be transmitted (S20). If it is to be transmitted, an ID number is entered in the user / user information element (S2).
1). After transmitting the call setting message (S22), it is determined whether a call setting accepting message has been received (S23).
If D is different, a disconnection message is sent from the network and received (S24). Since the user / user information can be added to this disconnection message, by examining this part, the communication terminal according to the present invention can determine whether the ID is different due to a preset disconnection reason code or not. It is possible to display to the calling user whether the call was disconnected for the reason (S25, S26, S27). Thereafter, the line is released (S28, S29).

On the other hand, if the call setting is accepted in step S23, a call message is received (S30), and it is displayed that the call is being called until the called party goes off-hook (S31).
Confirm the response of the called party by receiving the response message (S32)
The call display is stopped (S33), and the call state is set thereafter (S34).

FIG. 7 shows the flow of the receiving terminal. First, the call setting message is received (S40), and the operation is started.
The call setup then has user / user information,
Further, whether or not there is a code for identifying whether or not an ID number has been input to the user / user information element (S41), the user / user information element check is started (S42), and the predetermined ID is determined. If there is, an incoming ringing tone is sent out and a calling message is returned to the exchange (S43). After that, if it is hooked off (S44), a response message is sent (S45),
After receiving the response confirmation message (S46), enter the call (S4
7). If the IDs do not match or do not match, the reason is sent in the disconnection message and sent (S48). If not off-hook, the disconnection message without the user information element is sent out (S49), and the release message thereafter. Is received (S50), a release completion message is sent (S5).
1).

It should be noted that the procedure shown in the present embodiment is an example, and when message exchange is different, for example, even in abnormal communication, there is no problem as long as a predetermined message can be delivered at the time of establishing a call of this method. Further, as another embodiment, not only voice communication but also malicious communication can be eliminated before setting a call to a terminal of facsimile communication.

[Effect of the Invention] According to the present invention, an incoming call from a person who does not know the identification information of the called communication device can be rejected before the call is established, without providing the switching device with a special function. Therefore, for example, a wrong call or a mischievous call from a person who does not know the identification information of the called communication device can be prevented before setting up the call. Information according to the progress can be transmitted to the calling communication device.
That is, if the operator does not respond to the call despite notifying the calling communication device of the call of the called communication device, information indicating that the incoming call is rejected because there is no response from the operator is transmitted to the calling device. If the identification information transmitted by the calling communication device does not correspond to the stored identification information, the received identification information does not correspond to the stored identification information. Information indicating that the incoming call is rejected can be transmitted to the calling communication device. Further, when the identification information from the calling communication device is not received, information indicating that the incoming call is rejected because the identification information is not received can be transmitted to the calling communication device.
