Abstract

PURPOSE:To prevent the communication disturbance by executing the service in the case the identification number from an outgoing subscriber coincides with one of the identification numbers of the incoming connecting service classification registered in accordance with an incoming subscriber. CONSTITUTION:In the case there is an incoming to a subscriber 3 from a subscriber 5, an exchange 4 executes a regular incoming connection processing, when the subscriber 3 is in a free state, but informs a fact that the incoming is impossible to the subscriber 5 by a busy tone, in the case the subscriber 3 is not in a free state. In this case, when the subscriber 5 sends out its identification number beforehand after knowing a fact that the subscriber 3 is a contracting party of the incoming connecting service, and the identification number of the service classification, an exchange 6 sets allowable conditions such as call waiting, camp-on, message recording, etc., and incoming transfer, forced connection, message recording, etc., and also, interrupting connection, etc., in the case of a state that a handset is hooked off, in accordance with its service classification data, after sending out a busy tone, by which its service is executed. In such a way, a communication disturbance by many and unspecific outgoing subscribers is prevented.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for connecting the terminating subscriber under the initiative control of the originating subscriber when the terminating subscriber cannot be connected to the originating subscriber for some reason. The present invention relates to a calling party-controlled call termination connection system in which the call connection service desired by the originating subscriber is provided to the calling subscriber.

[Prior Art] Until now, there are services that allow a call between another calling subscriber and the called subscriber when the called subscriber is in a state of talking with a third party. The so-called Camp-On (this is the service name of Nippon Telegraph and Telephone Corporation, and the general service name is call waiting) is known. If a called subscriber who is in a busy state receives a call from a new calling subscriber, the called subscriber is notified of this by an incoming call display tone,
If the called subscriber performs a hooking operation in response to this, the called subscriber will be able to make a call with the new calling subscriber while keeping the connection with the third party on hold. ing. If the user performs the hooking operation again after the call ends, the call with the third party will be resumed.

In addition to the above, an "interrupt connection method" described in Japanese Patent Laid-Open No. 173962/1982 is known. In this case, when a called subscriber who is currently communicating receives an incoming call, the originating subscriber is notified that the subscriber is currently communicating.

If the calling subscriber sends a PIN number in response, the exchange accommodating the called subscriber checks whether the PIN number matches the PIN number for the called subscriber; Only if there is a match, the originating subscriber is connected to the terminating subscriber.

[Problems to be Solved by the Invention] However, in the case of the above-mentioned conventional technology, only predetermined uniform services can be provided, and the originating subscriber side can freely select the desired service from among various services. It has become something that cannot be selected.

In addition, while some services are provided based on the PIN number provided by the calling subscriber, some services are not based on the PIN number. A receiving subscriber in this state is at risk of having his or her calls or communications frequently interrupted by incoming calls from an unspecified number of calling subscribers.

Furthermore, it is impossible for the originating subscriber to proactively notify the terminating subscriber that the terminating subscriber has disconnected from the handset by using an interrupt call.

Incidentally, to explain this interrupt call, generally speaking, an interrupt call can be made in any state, such as in a busy state or when the handset is disconnected. However, in order to maintain communication secrecy, at present, fault detection is only performed when there is a request from a customer at the fault reception department of the exchange, and general subscribers cannot use it. However, this is only an operational restriction and does not correspond to a technical restriction. Therefore, interruption is possible no matter what state the subscriber is in, such as during a call or when the handset is off the hook. However, the original purpose of the barge-in is not to page the called subscriber;
Currently, the line status is grasped by interrupting the call line, and if the telephone is not in use, it is determined that the handset is disconnected, and the handset is disconnected by sending a howler sound etc. to the subscriber. The purpose of this service is to notify subscribers that they are out of service.

An object of the present invention is to enable a calling subscriber to arbitrarily select any terminating connection service from among a plurality of service types when the calling subscriber cannot be connected to the terminating subscriber for some reason;
Further, it is an object of the present invention to provide a calling side controlled call termination connection system in which a calling subscriber who is in a state of talking or communicating is not interrupted by an unspecified number of calling subscribers.

[Means for solving the problem] The above purpose is to prevent incoming calls from being received to a called subscriber who is unable to communicate with the calling subscriber due to a telephone call or the like.
If it is found in an automatic exchange that accommodates the called subscriber, the calling subscriber is notified by the exchange that it cannot connect to the called subscriber; If the PIN number from the calling subscriber is found in the automatic exchange, it is assumed that the called subscriber is a registered subscriber with a contract for the terminating connection service by referring to the subscriber data for the called subscriber. As such, the PIN number from the calling subscriber is registered for the receiving subscriber,
The incoming call connection service that matches one of the PIN numbers compatible with the type of incoming call connection service (specifically, call waiting connection, camp-on, call forwarding, forced connection, interrupt connection, message recording, etc.), and that the incoming call connection service related to the match is permitted. This is achieved by providing the matching termination connection service to the terminating subscriber only if the

[Operation] For general subscribers accommodated in an automatic exchange, the subscriber data registration area provided inside the exchange
Various types of information such as the status and subscriber class of each subscriber are stored as updatable, but in addition to this information, various incoming call connection services (specifically, call waiting connection, camp-on, call forwarding, forced connection, interrupt connection,
Message recording, etc.) is a unique password that can be updated and is registered in advance by the subscriber as incoming call connection service control information. By registering incoming call connection service control information, it is possible to handle incoming calls while the subscriber is, for example, on the phone or communicating.

In other words, if an incoming call from a certain originating subscriber is received by the automatic exchange accommodating the terminating subscriber while the terminating subscriber is on the phone, the calling subscriber is automatically notified. The exchange notifies the called subscriber that it cannot be connected, for example, by using a busy tone.

At that time, if the calling subscriber knows in advance the PIN number corresponding to the type of incoming call connection service registered by the called subscriber, the calling subscriber can take necessary measures based on the notification. be. When a calling subscriber sends a PIN number for a certain incoming connection service to an automatic switch, the automatic switch refers to the subscriber data for the called subscriber and determines the necessary information to carry out the incoming connection service. It performs control processing. The automatic exchange identifies from the subscriber class that the called subscriber is a registered subscriber for an incoming call connection service contract, and then uses the incoming call connection service in which the PIN from the calling subscriber is registered for the called subscriber. Only when the PIN number matches one of the PIN numbers corresponding to the type and the terminating connection service related to the match is permitted, the terminating connection service related to the match may be provided to the called subscriber for the first time.

[Example] The present invention will be explained below with reference to FIGS. 1 to 3.

First, the relay system according to the present invention will be explained. FIG. 2 shows an example of the relay system. As shown, in this example, each subscriber 1.3.5 has an automatic exchange 2
, 4.6, and subscriber 1 and subscriber 3 are placed in a talking state via exchange 2.4, and it is assumed that subscriber 5 calls subscriber 3 in this state. It has become a thing.

When the telephone number of subscriber 3 is dialed from subscriber 5,
The exchange 6 identifies that the subscriber 3 is accommodated in the exchange 4, and then sends the telephone number to the exchange 4. The exchange 4 knows from the telephone number that the call is for subscriber 3, but when a call is received for subscriber 3, the exchange 4 first checks whether subscriber 3 is free. It has become so. If subscriber 3 is free, normal incoming call connection processing is performed to connect subscriber 3 to subscriber 5.

Moreover, if there is no vacant state, a busy tone is sent to the subscriber 5. The subscriber 5 who hears this busy tone sends a PIN number corresponding to a certain incoming connection service as necessary, and the exchange 4 processes the incoming connection service based on the PIN number and the subscriber data corresponding to the subscriber 3. When it is determined whether or not to perform the incoming call connection service and the incoming call connection service processing is performed, the process for performing the incoming call connection service is executed, and a series of these processes will be described in detail later.

Figure 3 shows the incoming call translation table (
Part 7 of the subscriber data is shown. As shown in the figure, the incoming call translation table 7 stores updatable subscriber data for all subscribers accommodated in the exchange 4, using their telephone numbers as addresses. ing. In the illustrated example, an incoming call control flag F (indicating whether the subscriber is a subscriber with an incoming connection service contract) and a 0;1 identification number PW 1-PW are provided for each subscriber.
n, and further service type data 5IDI to 5IDn corresponding to identification numbers PW1 to PWn and service permission/denial data S
T1 to STn are stored as states associated with each other by pointer area 8. subscriber 3
When receiving a call, only when the calling subscriber 5 sends the nn identification number, the subscriber data corresponding to the subscriber 3 is referred to, and the incoming call connection is controlled. .

Now, FIG. 1 shows the flow of the originating side controlled incoming call connection processing in the exchange 4 in an example according to the present invention.

Assuming that subscriber 3 is called by subscriber 5 while subscriber 3 is in a busy state, the processing flow will be explained as follows.

That is, when there is an incoming call from subscriber 5 to subscriber 3, exchange 4 checks whether the previous subscriber 3 is free (processing step 8). If subscriber 3 is free, normal incoming call connection processing is performed for subscriber 3. Furthermore, if the call is not available, it is generally impossible to receive a call to subscriber 3, so subscriber 5 is notified of a busy tone (processing step 9). ). By hearing this busy tone, the subscriber 5 knows that it is not possible to receive normal calls at this time.

If the caller at subscriber 5 is a general person who does not know that subscriber 3 is a subscriber to the incoming call connection service, -
There is no other way than to wait for a chance to be connected if subscriber 3 is in an empty household by first performing the disconnection process and re-dialing, or if subscriber 3 is a subscriber to an incoming call connection service contract. Moreover, when subscriber 5 connects to subscriber 3 after knowing the password, subscriber 5 can take the necessary measures to complete the incoming call to subscriber 3. This is because the subscriber 5 can send a password corresponding to the desired service type from among the passwords corresponding to the type of incoming call connection service that can be known in advance. When the subscriber 5 sends a personal identification number, processing unique to the present invention is performed. After the exchange 4 sends the busy tone, the subscriber 5
Is it being monitored whether the PIN number has been sent or not?
Processing step 10): If the PIN number is not sent within a certain period of time, a disconnection process is forcibly performed; however, if the PIN number is sent within a certain period of time, a process unique to the present invention is performed. This is what is being done. In this process, first, the incoming call control flag F in the subscriber data corresponding to subscriber 3 is referred to and determined (processing step 11). From the state of this flag F, it is possible to know whether subscriber 3 is a contracted subscriber of the incoming call connection service.If subscriber 3 is not a contracted subscriber, a disconnection process is performed under the initiative control of exchange 4. ing.

If it is determined that the subscriber is a contract subscriber, the PIN number from subscriber 5 is officially received (processing step 12), and the PIN number or PIN number PWI~PW
It is determined whether or not it matches any of n (processing step 13). If the password does not match any of the passwords PWI to PWn, a disconnection process is performed under the initiative control of the exchange 4, while if the password matches any of the passwords, it is further stored as a pair in the password associated with the match. The service permission data is referred to and it is checked whether the incoming call connection service desired by the subscriber 5 is available for connection (processing step 14). That is,
If the incoming call connection service desired by the subscriber 5 is in a connectable state, the disconnection process is performed under the initiative control of the exchange 4, while the incoming call connection service desired by the subscriber 5 is in a connectable state. In some cases, the service type data stored as a pair with the matching password is referenced and identified (processing step 15).

Thereafter, the process branches to a process corresponding to the incoming connection service indicated by the service type data (processing step 16), and call waiting incoming process, interrupt connection process, forced incoming call process, etc. are performed according to the service type data. (processing steps 17, 18.19)
. Incidentally, here, to give an example of a state in which it is possible to connect to the call connection service, the types of incoming call connection services that are allowed when subscriber 3 is in the busy state are call waiting, camp-on, and message. Possible types of incoming call connection services when the handset is disconnected include incoming call transfer, forced connection, and message recording. Furthermore, interrupt connection is possible by setting permission conditions that allow connection in all states.

Finally, a brief explanation of some of the incoming call connection services targeted by the present invention, namely message recording, is as follows.

Message recording: A service that records messages from the calling subscriber by dialing a special number after hooking when the called subscriber is busy and a busy tone is notified to the calling subscriber.

During the recording, a message U is sent to the incoming subscriber during the call.
Since the caller is notified of the message, the called subscriber can listen to the message by dialing the special number after the call ends.

[Effects of the Invention] As explained above, according to the present invention, when the originating subscriber cannot be connected to the terminating subscriber for some reason,
Any incoming call connection service can be arbitrarily selected from among a plurality of service types, and the incoming subscriber who is in the middle of a call or communication can be called or Communication is prevented from being interfered with.

Claims (1)

[Scope of Claims] 1. If an incoming call to a called subscriber who is unable to communicate with the calling subscriber due to a telephone call or the like is received by the automatic exchange that accommodates the called subscriber, In this case, after the calling subscriber is notified by the exchange that it cannot connect to the called subscriber, the PIN number sent from the calling subscriber based on the notification is sent to the automatic exchange. If so, by referring to the subscriber data corresponding to the called subscriber, the PIN number from the calling subscriber can be determined to be compatible with the called subscriber, assuming that the called subscriber is a subscriber registered with a contract for the incoming call connection service. The incoming call connection service related to the match will be provided to the incoming subscriber only if the PIN number matches one of the PIN numbers corresponding to the incoming call connection service type registered in , and the incoming call connection service related to the match is permitted.
