Abstract

PURPOSE:To stop the incoming call in an unsuitable time zone to a subscriber waiting for an incoming call by referring to a storage device which displays the propriety of the incoming call acceptance of the subscriber when a center device calls the subscriber for connection. CONSTITUTION:A voice message accumulator 6 is provided in a center device 10 and a controller 5 controls a line circuit 4 and the accumulator 6. When the center device 10 calls a subscriber 2 waiting for an incoming call for connecting the call of an originating subscriber 1, the accumulator 6 which displays the propriety of the acceptance of incoming call of the subscriber 2 is referred to. When the subscriber 2 can accept an incoming call, the center device 10 connects the call from the originating subscriber 1 to the incoming call waiting subscriber 2 after calling the subscriber 2. When the subscriber 2 cannot accept the incoming call, the device 10 informs the subscriber 1 of the communication impossible state. Thus the incoming call in a time zone during which the incoming calling waiting subscriber cannot accept a call can be stopped.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a communication network in which when a subscriber selects a partner, information corresponding to the communication purpose is provided regardless of the number corresponding to the partner subscriber. Regarding a communication connection method in which a device called the other party intervenes and this device calls the other party as necessary and mediates the connection to achieve the purpose of communication, the time period during which incoming connections are possible for users who wish to receive calls in particular. The present invention relates to a communication network connection control system that provides an interface that allows the user to specify a bandwidth, thereby providing an easy-to-use service.

Conventionally, in this type of communication connection system, a plurality of subscribers who wish to receive a call register their desired purpose of communication in the form of a voice message, etc. in a center device, and a calling subscriber who searches for the voice message receives the voice message. When a subscriber listens to a call and wishes to make a call with a subscriber who meets the conditions, a connection is established with the desired subscriber who has been registered in advance and is waiting for an incoming call.

[Problem to be solved by the invention]

Multiple subscribers who wish to receive a call register their desired purpose of communication in the form of a voice message, etc. in the center device, and the originating subscriber who searches for the voice message listens to the voice message and determines that it meets the conditions. When you want to make a call, even if you are a subscriber who has registered in advance and is waiting for a call, there may be circumstances where you are unable to accept the call, or you may be in trouble if the call is received. With this method, even in such a case, it was not possible to stop outgoing connections from the center.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned drawbacks and provide a method for stopping incoming calls at times that are inconvenient for the subscriber desiring to receive calls.

[Means for Solving the Problem] In order to achieve the above object, the present invention registers the subscriber numbers of a plurality of subscribers who wish to receive calls, code information indicating whether or not to accept incoming calls, and a message indicating the purpose of communication. A center device equipped with a storage device for voice messages is connected to a 1ffl communication network, and a calling subscriber connected to said communication network connects to said center device, and then sends a call to a subscriber who wants to receive a call connected to said communication network. By searching for registered messages,
A connection control system for a communication connection system that sets up a communication path between the originating subscriber and a subscriber desired to receive a call designated by the originating subscriber, wherein the center device makes a call to the subscriber desired to receive a call. When making a connection, refer to a storage device that displays whether or not the incoming call of the desired subscriber can accept the call, and if the incoming call can be accepted, make an outgoing connection to the desired incoming subscriber, and then connect the calling subscriber and the desired incoming subscriber; This is a connection control method characterized by reporting the call-disabled state to the originating subscriber when the incoming call cannot be accepted.

[For production]

In order to stop incoming calls at times that are inconvenient for the subscriber who wants to receive calls, the present invention provides a function for the subscriber who wants to receive calls to stop calls from the center by his own operation, and a function to specify the stop time period. and to the originating subscriber.
Since the center equipment is equipped with a function to notify the time when calls will be available, subscribers who wish to receive calls can stop or cancel the service at their own will, even if they do not want to receive a call from the center. For subscribers who wish to receive calls, they can control the service and use it flexibly to suit their convenience. Examples will be described below based on the drawings.

〔Example〕

FIG. 1 is a system configuration diagram that realizes this service.

As shown in FIG. 1, 1 is a calling subscriber and 2 is a subscriber who wants to receive a call, both of which are telephone terminals.

3 is a public telephone network; 4, 5, and 6 are main components of the center device 10 according to the present invention; 4 is a telephone line line circuit; 6 is a voice message storage device; and 5 is a line circuit 4. Accumulation′! This is a control unit that controls the A position 6. In the storage device 6, the content of the purpose of communication is registered in advance in the form of a voice message by a user, such as the subscriber 2 desiring to receive a call. A user, for example, a calling subscriber 1, dials into the center device 10 through a normal telephone connection, and
It is configured to listen to voice messages sent from a storage device 2, and to make a direct call via a line circuit 4 to a subscriber 2 who wishes to receive a call, who is a registrant of the voice message, if necessary.

Figure 2 shows 1 of the communication sequence when implementing a service.
This is an example.

As shown in FIG. 2, the originating subscriber connects to the center device (hereinafter referred to as the center) by making a call and dialing the telephone number I1 in the usual way. After confirming the response from the center, the originating subscriber sends a search request signal consisting of a specific predetermined code string to the center using a telephone (hereinafter abbreviated as PB), and then the center registers the subscriber. The received voice messages are sent out sequentially from number 1 to number 0.

The originating subscriber listens to all or part of the information, and when he or she determines that voice message No. 4 best matches his or her conditions, and voice message No. 7 is the next best information, The originating subscriber will wish to communicate with the subscriber of the voice message. First, in order to talk to the registrant of voice message No. 4, a call request interrupt signal consisting of a predetermined code string and information about voice message No. 4 are sent to the center using PB. The center receives the call request signal and the information on number 4 of the voice message, looks up a table for indexing the subscriber address, and refers to the call acceptance/rejection indication bit of the destination station. In the example shown in Figure 2, the incoming call indication bit for voice message number 4 is 1, meaning that incoming calls are stopped, so based on the specified stop time, it is currently not possible to make a call to the originating subscriber line. This system uses audio guidance to report the time it takes to pass.

(3rd member Susumu learns that he is unable to communicate with voice message registrant No. 4, and wishes to talk to the deputy colonel's voice message registrant No. 7. As shown in Figure 2, he tries PB again. The center uses the above-mentioned call request interrupt signal and the information of voice message No. 7 to be sent to the center.As mentioned above, the center also retrieves the incoming acceptance indication bit of registration # of voice message No. 7 from the subscriber index table. Since 3 incoming calls are allowed, the sequence is to retrieve the subscriber's address and make an outgoing connection from the center.

The present invention described above is a voice message search method in which an interrupt signal indicating a call request is sent out while the originating subscriber is listening to a registered voice message, and when the center receives the signal, It goes without saying that the same structure can be applied to a method of subtracting the subscriber address of the registrant from the voice message number being sent.

In addition, in the above method, at the time when the calling subscriber searches, registered information for which the subscriber who wishes to receive calls does not want to receive calls is not included in the search target, or when the calling subscriber searches, the information is not included in the search. There are various ways to use f+, such as how to notify the caller of the IJI who is the searcher using voice guidance or busy tone.

Note that it is obvious that the present invention can be applied not only to telephone networks but also to data exchange 114 in exactly the same way, just by changing the media type from voice to data code information, so a detailed explanation will be omitted. .

〔Effect of the invention〕

As described above, the present invention provides a connection control system that allows i-hop subscribers to stop/cancel the service at their own will, even when they do not want to receive a call from the center. Compared to conventional technology, this method has the effect of improving the man-machine interface for providing services from the user's perspective and making it easier to use. .

Therefore, subscribers who wish to receive calls have the advantage of being able to control the service and use it flexibly according to their own convenience.
