Abstract

PURPOSE:To attain the application of incoming call reject control on each occasion in response to an opposite party recognized from a display content of an opposite subscriber number or the like during the arrival of a call by inputting a call arrival reject to allow the called party to apply interruption processing actively during the arrival of a call. CONSTITUTION:After an opposite party is confirmed while observing caller identification information displayed by a display section 5 during the arrival of a call, when the opposite party is a party not requiring the rejection of an incoming call, the call is replied via the operation such as hook-off and when the party is a party requiring incoming reject, an incoming call reject signal input section 7 inputs an incoming reject command. An incoming call reject processing section 8 prepares a line interrupt message by the incoming reject command and the message is sent to the line on each occasion to release the incoming call state. The incoming call reject command is regenerated actively as required from the called party side during the arrival of a call and the interrupt processing is applied without reply to the incoming call, then the registration of a subscriber number of a terminal equipment desiring the incoming call reject is not required, and it is not required to await the abort of the call by the opposite party.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to incoming call rejection control for communication equipment connected to an integrated digital service network.

(Prior Technology) Today, telephone and facsimile WAr! An integrated digital service network (hereinafter referred to as 15DN) is being put into practical use as a digital communication network that integrally handles communication services related to communication devices with different characteristics.

As is well known, L5DN has the additional function of notifying calling party identification information such as the subscriber number of the other party when receiving a call from the network, and on the receiving side, the calling party identification information is displayed to the operator. It is becoming known.

On the other hand, with regard to communication services using the I5DN, from the viewpoint of efficient operation, there is a demand for accepting only incoming calls from specific parties and restricting incoming calls from other parties.

In order to respond to this request, in conventional communication equipment compatible with I5DN, subscriber number 1 of a specific terminal that wishes to reject calls is registered in advance, and the subscriber number of the other party notified from the IsON upon receiving a call is registered. A call restriction method was adopted in which the incoming call was rejected only if the call matched the already accepted call.

However, with this method, all incoming calls from unregistered terminals are accepted, so if you want to achieve reliable incoming call control, be sure to register the subscriber numbers of many terminals that you wish to reject. However, due to the complexity of registration operations, efficient operation could not be expected.

In addition, if you receive an incoming call on a fusuma or are forced to recognize the calling party's subscriber number displayed on the called party and are forced to reject the call, either wait until the other party abandons the call, or Alternatively, there is a method of responding once and disconnecting immediately, but in the former method, the waiting time depends on the actions of the other party, and in the conventional method, the other party is forced to pay unnecessary charges.

(Problem to be Solved by the Invention) As described above, in the above-mentioned conventional communication equipment, in order to securely control incoming call rejection, it is necessary to register all the subscriber numbers of the other parties who wish to reject incoming calls. This resulted in complicated operations.

In addition, as an exceptional measure, after the call is incoming and the called party's identification information is displayed on the called party, if necessary, wait until the other party abandons the call, or - immediately after answering the call. Although it was possible to reject the incoming call by disconnecting, there were problems in this case, such as a considerable amount of waiting time and unnecessary charges being forced on the other party.

The present invention has been made in view of the above-mentioned circumstances, and allows you to freely check the displayed identification information of the other party while receiving a call, without having to register the subscriber number of the other party who wishes to reject the call. A communication device that can perform incoming call rejection control for each terminal on a case-by-case basis, and can efficiently release incoming calls without having to wait a long time until the other party gives up on the call or forcing the other party to incur unnecessary charges. The purpose is to provide

[Structure of the invention]

(Means for Solving the Problems) The communication device of the present invention provides W from an integrated digital service network.
an incoming call notification means for notifying that the call is on the line; a display means for displaying calling party identification information notified from the integrated digital service network in connection with the incoming call; , an incoming call rejection command input means for inputting an incoming call rejection command to refuse a response to the incoming call each time, and a disconnection message to the integrated digital service network based on the incoming call rejection command input from the incoming call rejection command input means. and an incoming call rejection processing means for sending out a call.

(Function) In the communication device of the present invention, when a call is being received, after recognizing the other party by looking at the displayed calling party identification information, if the other party does not require incoming call rejection, the communication device responds to the call through an operation such as hooking off. , if the other party requires incoming call rejection, the incoming call rejection command can be inputted from the incoming call rejection command input means.

In response to this incoming call rejection command, a line disconnection message is created by the incoming call rejection processing means, and this message is sent to the line each time to release the incoming call status.

In this way, while a call is being received, the called side can actively issue a call rejection command as necessary and disconnect the call without responding to the call, so that subscriber 1 of the terminal who wishes to reject the call can
Not only is there no need to register a number, there is no need to wait until the other party gives up on calling, and there is no need to force unnecessary charges on the other party.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 shows an embodiment of the communication separate device according to the present invention, in which 15 ON times 411, signal input terminal 2, communication control section 3, incoming call detection section 4, display section 5, communication section 6, communication It is configured to include a rejection command input section 7, a communication rejection processing section 8, and a main control section 9.

The operation of this communication device at the time of incoming and outgoing calls will be explained in detail by taking the telephone function as an example, with reference to the flowchart shown in FIG.

First, when there is a call from the 15ON line 1 while in the waiting state, the incoming signal at this time is taken in from the input terminal 2 and notified to the communication control ig3.

The incoming call detection section 4 analyzes the contents of the incoming signal notified to the communication control section 3, and performs a capability check to see whether the device can receive the signal (step 201).

Specifically, this incoming signal has a format as shown in FIG. 3, and is usually called a call setup message.

It should be noted that although FIG. 3 is divided into four parts due to the relationship between the information groups of the call setting message, they should be viewed as one in view of their original nature.

The call setup message in Figure 3 includes a protocol identifier (A), message type (B), transmission capability (C), channel identifier (D), calling number (E), and calling subaddress (F).
), dish number (G), dish sub-address (H), low layer consistency (1), high layer consistency LJ), etc., and each of these information elements consists of 1 to 5 octets. The calls are received from the calling party in the order shown on the left side of the diagram.

The capability check performed in step 201 is a process of searching for whether or not the transfer capability information element, higher layer compatibility information element, etc. in the call setup message are added to the functions of the device itself.

In this process, if it is recognized that the call cannot be received due to the different additional functions, the main control unit 9 sends a release completion message to the 15DN 111 through the communication control unit 3 in response to the incoming call (step 202); Return to standby state.

On the other hand, in the process of step 201, if it is recognized that the call can be received due to the matching of the additional functions, the main control unit 9 sends a paging message to l5DN number a1 through the communication control unit 3 in order to accept the incoming call. In step 203), the li caller is notified that the device is in a calling state.

Subsequently, the main control unit 9 determines whether or not the call setup message retrieved in step 201 contains information that can identify the calling party (calling number and calling subaddress) (step 204), and if so, the The contents are displayed on the display section 5 (step 205).

For example, taking the call setup message in FIG. 3 as an example, both the address information "O35222000" in the calling number information element and the address information "111" in the calling subaddress information element are used as information that can identify the terminal on the other end. exists, so both of these are '03522200
The information is displayed on the display section 5 in a format such as 0-111''.

At the same time, the main control section 9 drives a ringing means (not shown) to generate a ringing tone and notifies the operator of the @ signal (step 206).

If it is recognized in step 204 that the calling party identification information (optical number and calling subaddress) is not included in the call setup message, the main control unit 9 immediately returns to step 20.
6 incoming call notification.

Now, in step 204, Q with notification of calling party identification information.
It is assumed that an incoming call notification is issued in step 206 while fi is made and this is displayed on the display 8115 in step 205.

Through these processes, the operator on the receiving side can know which party the call is currently receiving and whether it should answer the call depending on the party.
(ΔYou can choose whether to reject it or not.

In the case of the communication VI device of the present invention, during the above-mentioned communication, especially when attempting to reject an incoming call, the communication rejection command input section 7
A communication rejection command can be input by operating a predetermined key.

During this time (after step 206), the main control unit 9 monitors whether the calling party has disconnected the line, and whether or not a call rejection command has been input from the called party, or whether a call rejection command has been input. Whether or not the incoming call is answered without being received is monitored in order (steps 207 to 209).

First, when it is recognized in step 207 that the calling party has disconnected the line, the ringing tone is immediately stopped (step 210), and a release message is sent to the 15DN line 1 through the communication control unit 3, and the calling party After notifying the user that the line has been disconnected (step 211), it returns to the standby state @
do.

It is also assumed that the process reaches step 208 without going through the line disconnection process, and that it is recognized here that a communication rejection command has been input.

In this case as well, the main control unit 9 immediately stops the ringing sound (step 212), but thereafter sends an incoming call rejection disconnection message in a format different from the release message in step 211 (step 213), and then returns to the standby state. do.

A specific example of this incoming call rejection disconnection message has a format as shown in FIG.

The incoming call rejection disconnection message shown in Figure 4 includes a protocol identifier (K), message type (L), and reason indication (M).
Each of these information elements is configured into octets and is transmitted to the calling party in the order shown at the left end of the figure.

In the communication device of the present invention, the A-call rejection processing unit 8 performs processing such that user communication rejection is used as the reason type in octet 4 in the reason display information element in this incoming call rejection disconnection message, and the incoming call rejection created thereby. A disconnection message is sent back to the calling party through the communication control unit 3.

The calling party receives this incoming call rejection disconnection message and is disconnected without the line being connected, so the call can be played without incurring any charges.

In addition, when a call is being received, a command to reject the call is input according to the other party displayed on the display unit 5, and the called party actively disconnects the call. There is no need to wait until you give up.

Furthermore, when the above process is viewed from the network side, it leads to the resolution of ringing calls that are not answered, and therefore it is possible to significantly reduce the number of faulty lines on hold.

Note that the process reaches step 209 without inputting the incoming call rejection command in step 208, and the operation to answer the call (
If the hook-off, etc.) is not performed, the main control unit 9 further repeats the processing from step 207.

Furthermore, if a call response operation is performed in step 209,
The main control unit 9 immediately stops the ringing sound in step 21.
4) After sending a response message indicating that the incoming call has been answered to the SDN line 1 (step 215), the communication section 6 shifts to a state in which the call is in progress.

〔Effect of the invention〕

As explained above, according to the communication device of the present invention, when a call is being received, a call rejection command is input and the call recipient actively disconnects the call. Even if you do not set up a call, you can activate call rejection control each time you recognize the other party from the display contents such as the other party's subscriber number while receiving a call. It has the excellent advantage of being able to resolve incoming calls extremely efficiently without forcing charges.
