DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telecommunications service centered on a telephone service, and in a case where a caller cannot establish a connection of a communication line to a specific subscriber, the caller is sent from the specific subscriber. And a notification method of call occurrence information for retrying connection.

[0002]

2. Description of the Related Art Conventionally, when a large number of calls are simultaneously received by a specific subscriber having a plurality of lines, such as a customer support of a product, all the lines owned by the subscriber are received. It will be in use. Also, in the case of congestion in a telecommunications network, incoming calls to a specific subscriber cannot be made. In such a case, the caller may either try calling again or use the automatic recall (CC) provided by the telecommunications network.
BS: Completion of Call to
Using a Busy Subscriber service, a line is automatically connected by a function of a telecommunications network when the line becomes free, or there is only one method. However, it is clear that the former method cannot be connected no matter how many times a call is made during a congested state or when all the lines of a specific subscriber are used. Cannot be controlled by the will of a particular subscriber.

[0003]

As described above, in the conventional telephone service, a large number of calls are concentrated on a specific subscriber,
When congestion occurs in a telecommunications network, connection to a line has been impossible. An object of the present invention is to solve such a conventional problem and to provide a call origination information notification method that can be called back without re-calling even when line connection to a specific subscriber is impossible. It is in.

[0004]

In order to achieve the above object, according to the method for notifying call occurrence information according to the present invention, when a caller makes a call to a specific subscriber, but the line cannot be connected, the specific subscriber has By providing information to the computer and leaving the processing related to the line connection to a specific subscriber, re-calling of the caller becomes unnecessary, and the line is connected under the control of the specific subscriber. If the specific subscriber determines that the connection is unnecessary, it is possible not to call back. That is, when the caller cannot make a line connection, the information about the incomplete call including the caller identification information is stored in a database in the service control device in the telecommunication network, and the service control device is stored in the specific subscriber. By connecting to the computer, the specific subscriber is notified of the information at an occasion desired by the specific subscriber, and the subsequent processing is executed based on the will of the specific subscriber.

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a connection diagram of a notification system of call occurrence information according to an embodiment of the present invention. A plurality of switching devices 2 and 10 exist in the telecommunications network, and accommodate lines 8 and 9 connected to communication devices of a caller 1 and a specific subscriber 7 which are communication entities using the network. doing. The switching devices 2 and 10 transmit communication information to each other via the relay network 3. In addition, even if the switching device 2 that accommodates the line 8 and the switching device 10 that accommodates the line 9 are the same switching device,
Further, the present invention is applicable to different switching devices as shown here. The service control device 4 includes a database 11 capable of storing information on a caller whose line connection to a specific subscriber has become impossible. Also,
The switching device 2 and the service control device 4 in the telecommunications network are connected by transmission means 12, and the service control device 4 and the computer 5 of the specific subscriber are connected by another transmission means 13, and these transmissions are performed. Information can be transmitted and received via the means 12 and 13, and an information notification means based on the present invention can be realized. The computer 5 and the terminal 6 in the facility owned by the customer are connected by a transmission unit 14, and the computer 5 can transmit and receive information for controlling the operation of the terminal 6 via the transmission unit 14. Here, the transmission means 12 between the switching device 2 and the service control device 4 uses the common channel signaling system No. defined by the International Standards Organization ITU-T. 7 It is used on a daily basis to control services (for example, to specify a connection destination telephone number in a toll-free service). The transmission means 13 connecting the service control device 4 and the computer 5 is a means for connecting a user (specific subscriber) to a network, so that the Internet, which can be accessed by many users,
It comprises a packet switching network, a D channel of an ISDN network, a dedicated line, and the like. In recent years, there is a computer having a telephone function as a peripheral device, and in this case, the transmission unit 14 from the computer 5 to the terminal 6 is
It represents the wiring connecting the peripheral device and the computer.

FIG. 2 is a sequence chart of information exchange between a caller and a service control device according to an embodiment of the present invention. When the caller 1 calls a specific subscriber (specific subscriber 7 in this case), but the line connection fails because the call is rejected by the relay network 3, information on the call including the caller identification information is transmitted to the service control device. Database 11 in 4
Is stored according to the procedure shown in FIG. Alternatively, when the line connection becomes impossible, the same information as described above is stored in the database 11 in the service control device 4 according to the procedure of FIG.
First, the caller 1 transmits a call signal 15 through the line 8 to request a line connection to a specific subscriber. The switching device 2 which has detected the calling signal 15 should recognize the identification number information of the specific subscriber in the calling signal 15 and notify the service control device 3 when the line connection is impossible. Recognize that there is. The switching device 2 transmits a line connection request signal 16 to the relay network 3. The relay network 3 tries to connect based on the specific subscriber identification information in the line connection request signal 16, but recognizes that a line cannot be established due to reasons such as line busy, network busy, congestion, etc. A line release signal 17 is transmitted to the switching device 2. Since the connection to the line requested by the caller could not be established, the switching device 2 sends a storage request signal 18 including the identification information of the caller 1 and the identification information of the specific subscriber to the service control device 4 through the transmission means 12. Send.

[0007] The service control device 4 stores the received caller identification information, the specific subscriber identification information, and additional information such as the current date and time in the database 11. Also, when the caller 1 transmits the call signal 19 and it is determined from the information in the switching device 2 that the line cannot be established, the storage request signal 20 is transmitted from the switching device 2 to the service control device. 4, and the service control device 4 stores the same information in the database 11. The service control device 4 transmits the information stored in the database to the computer owned by the specific subscriber. It should be noted that when a specific subscriber makes a service contract, a notification contract (for example,
Requesting notification every three minutes), and the service control device determines the timing of each notification. FIG. 4 is a configuration diagram of data stored in a database of a service control device according to an embodiment of the present invention. In FIG. 4, the transmission means 1
As an example, assuming that the Internet is used, an IP address is adopted as information for identifying the computer 5 connected to the transmission unit 13. Data 1 in FIG. 4A is data input at the time of a service contract with a specific subscriber, and holds an IP address to be notified when the telephone number of the specific subscriber is reached, and a notification trigger. . 4B is a storage request signal 1
It is updated by 8, 20 and records the telephone number of the caller and the date and time when the call was attempted but was not connected. Data 1 and data 2 of FIG. 4 are stored in the database 11 of the service control device 4.

FIG. 3 is a sequence chart of information exchange between a service control device and a specific subscriber terminal according to an embodiment of the present invention. Continuing with FIG. 2, the information including the caller identification information stored in the database 11 in the service control device 4 is notified to the computer 5 of the specific subscriber by the procedure of FIG. 6 calls the caller. Alternatively, the connection to the caller is prevented from being determined by the computer 5. First, the service control device 4 recognizes that it is time to notify the information stored in the database 11 to the specific subscriber based on the request condition from the specific subscriber, and
3, a call occurrence notification signal 21 is transmitted. The computer 5 of the specific subscriber recognizes the necessity of the line connection to the caller based on the received information, and transmits a call request signal 22 to the specific subscriber terminal 6 through the transmission means 14. The specific subscriber terminal 6 performs a line connection process to the caller based on the received information, and performs a connection process between the specific subscriber 7 and the caller 1. In addition, the computer 5 of the specific subscriber receives the call occurrence notification signal 23, and the line connection is not established due to, for example, a difference between the time information of the caller calling and the current time exceeding a reference value. If it is determined that it is necessary, the subsequent processing may not be performed. For example, if the computer 5 is set in advance so as not to call back a malicious caller based on the judgment of the specific subscriber, unnecessary connection can be avoided.

[0009]

As described above, according to the present invention,
Even if the line connection to the specific subscriber is not possible, it is not necessary to repeat the call of the caller and the call can be returned under the control of the specific subscriber, so that the possibility of establishing the connection is improved.
In addition, since it is possible not to make a call back according to the judgment of the specific subscriber, unnecessary connection such as a malicious call can be avoided.
