Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention improves the function and sophistication of a relay system of a communication network, so that a caller on the receiving side can make a simultaneous call to a plurality of numbers on the receiving side or a destination of the receiving side. The present invention relates to an incoming call connection method for a plurality of numbers that can be changed.

2. Description of the Related Art In a conventional telephone incoming call connecting method, a call line is provided between control system devices of an exchange and a dedicated signal line (common line signal system) is provided. this house,
As for the signal line, all required signals are transmitted and received in a data transmission format on a plurality of lines between both exchanges. In addition, as for the communication line, one input line can be connected to any one of a plurality of output lines, and this serves as a route for audio signals. The call path provided with the call line is a subscriber circuit that detects a call from the subscriber and activates the exchange, a switch that connects one input line to an arbitrary output line, and a call current is supplied to the call state (response , The end of the call) and a trunk device for monitoring the repeater ("New Easy Telecommunications Technology," 1977, March 3).
Published by Orm Co., Ltd. on March 15, pp.25-65). Also, in the conventional home telephone, the central line is usually connected to the automatic exchange, but when the power switch of the operation console is turned off, the idle line is immediately switched to the direct telephone, and the busy line automatically waits for the end of the call. There is a function of directly switching to a direct-dial telephone, that is, an automatic night-time switching function, and a transfer telephone function in which a call received in advance is set to be transferred to a specific number. However, these must be fixedly set in advance, and the switching destination number or the transfer destination number is a predetermined number. Furthermore, the transfer destination could only be changed from the telephone number with which the service contract was made.

[0003]

As described above, in the conventional telephone incoming call connecting method, since the relationship between the caller and the called party in the call connecting process is always one-to-one or many-to-one, one telephone number is used. If you call, the call will actually be made to only one number. That is, in the conventional incoming call method, one incoming call is made only for one outgoing call. Now, when making a call to a plurality of called numbers which are completely different on the called side, for example, a number of the regional network A, a number of the regional network B and a number of the mobile communication network, which are respectively owned by different operators, Had to make three calls with each number. That is, in the conventional incoming call connection method, when making a call to a plurality of numbers at the same time, it is necessary to make a call a plurality of times with each number. Further, there is a nighttime switching function and a forwarding telephone function, but these are for switching or forwarding to a specific telephone number and cannot be arbitrary numbers. Further, as conventional techniques, there are services such as a free dial and a dial Q. In these methods, a service control device is arranged in the network so that the originating exchange can control this service. The device is accessed, the service condition of the called number is searched, and the required service is performed. However, even with these methods, there is no function for processing incoming calls to multiple numbers in the regional network and relay network. An object of the present invention is to solve such a conventional problem, to enable incoming calls to a plurality of numbers on the called side with one call, and to change the called party regardless of where the called side subscriber is. It is to provide an incoming call connection method to multiple numbers that can be performed.

[0004]

In order to achieve the above object, a method of connecting a telephone call to a plurality of numbers according to the present invention is a communication network (2) in a public communication network composed of a plurality of communication networks.

0) and the relay exchange apparatus (100) receives the relayed telephone number, analyzes the telephone number and sends an inquiry signal to the service control apparatus (200), and the service control apparatus (200). 200) receives the inquiry signal, refers to the subscriber service file (201) and extracts a plurality of called numbers from the service conditions of the called number,
The relay exchange device (100) is notified, and the relay exchange device (100) that has received the notification performs incoming call control to a plurality of received call destination numbers.

[0005]

According to the present invention, a relay tandem switching device and a service control device are installed in the regional network, and the relay switching device mainly performs the incoming call processing to a plurality of numbers. Conversion processing from one number to a plurality of numbers is mainly performed. These two devices exchange necessary information via, for example, the common line signal network, so that incoming processing for a plurality of numbers can be performed. The subscriber registers a plurality of incoming numbers in the service file of the service control device in advance, but when changing these numbers, dial the special number for changing the service conditions or directly from the subscriber. By reporting the change, it can be changed automatically or by the maintainer. As a changing method, a service menu for number selection is prepared as a service condition of the service control device, and this menu is displayed on the calling side by the guidance so that the service can be selected. As a result, it is possible to make a call to a plurality of numbers on the called side by making one call. In addition, the call can be received by registering the change of the called party regardless of where the called party is.

The operation of each functional block will be described below.
FIG. 7 and FIG. 8 are connection sequence charts when a plurality of numbers are received by a regional network subscriber according to the present invention. Now
It is assumed that a subscriber of the regional network A receives a call to a subscriber of the regional network B. After the terminal off-hooks, the subscriber of the regional network A dials the telephone number of the destination subscriber, that is, the number to which the destination subscriber belongs to the regional network B. This dial number is transferred as an address signal to the switching device 300 of the regional network A, the switching device 100 of the relay network, and the switching device 300 of the regional network B. Up to this point, the operation is the same as the conventional connection operation. Next, the relay exchange apparatus 100 of the regional network B
When the address signal is received, the received dial number is analyzed. For example, it is determined whether or not it is a dial number registered in the service implemented in the present invention. Then, the relay exchange apparatus 100 sends an inquiry signal (subscriber data inquiry signal) to the service control apparatus 200 together with the dial number and the calling ID number. The inquiry is made in the inquiry unit 101 of the relay exchange apparatus 100, and at the same time, the calling ID number is transferred from the ID transfer unit 105. When the service control device 200 receives the inquiry signal from the repeater exchange device 100, the subscriber service file 2 in which the service conditions of the subscriber, the connection destination number, etc. are stored.
01, and the connection destination designating unit 205 determines whether or not the connection is possible and the designation of the connection destination based on the calling ID received from the relay exchange apparatus 100. For example, service file 20
Since calling ID information for refusing the connection, connection destination information, etc. are stored in 1 as service conditions, the above operation is executed by accessing them. It should be noted that the connection destination information is information that specifies which one of the terminals and mobile terminals in the regional network to connect to when the called subscriber has a terminal or a mobile terminal.

The operation examples of FIGS. 7 and 8 show the connection when the called subscriber has a plurality of terminals in the same regional network. First, the calling subscriber turns off the hook and turns the dial so that the address signal is transmitted from the subscriber switching device 300 to the relay switching devices 100 and then to the server.
The data is transferred to the relay exchange apparatus 100 connected to the service control apparatus 200, and the relay exchange apparatus 100 sends a subscriber data inquiry signal to the service control apparatus 200. In the service control device 200, the destination determination unit 20
In step 2, the service file 201 is accessed based on the connection destination determined by the connection destination designation unit 205, and the dial numbers of a plurality of call destinations are determined. Here, the dial numbers of a plurality of terminals in the regional network B are determined. Then, when the service control device 200 determines a plurality of call destinations, the notification unit 2
The subscriber data inquiry response signal is returned to the relay exchange apparatus 100 via 03 together with connection information (connection type, number of destination numbers, destination number) and billing signal request flag. Upon receiving this information, the repeater switching apparatus 100 returns a ringback tone (RBT) to the originating side, and at the same time, sends an address signal to the plurality of subscriber switching apparatuses 300 of the connection destinations and simultaneously calls a plurality of terminals. I do. When any one of the called terminals goes off-hook, the response signal is returned to the calling side via the relay exchange apparatus 100 and the call is started. After the call, the disconnect sequence is shown when the calling party first goes on-hook and when the called party goes on-hook first. That is, when the calling side first goes on-hook, a disconnection signal is sent to the called side to let the called-side subscriber hear a business tone, and if the called-side subscriber goes on-hook, a recovery completion signal is sent to the calling side. Send out. When the called party first goes on-hook, it sends an interruption signal to the calling party to let the calling subscriber hear a business tone, and when the called party goes on-hook, sends a disconnect signal to the called party. Then, the restoration completion signal is returned from the receiving side to the calling side. These procedures are the same as conventional ones.

FIGS. 9, 10 and 11 are sequence charts showing the procedure when the calling side dials the dial number of the area B, but the subscriber designates the terminal of the mobile communication network as the called terminal. -It is. As in the case of FIGS. 7 and 8, when the repeater switching apparatus 100 sends a subscriber data inquiry signal to the service control apparatus 200, the service control apparatus 200 receives the call at the terminal of the mobile communication network. Send back a response to control. As a result, the relay exchange apparatus 100 performs incoming call connection control via the gateway exchange apparatus 500. When the mobile terminal goes off-hook, a response signal is sent back to the calling side. Since this incoming call control is the same as the normal incoming call control, the description of the operation is omitted. When the call ends, the sequence differs between the first call and the first call. At the time of calling to the destination, when the calling subscriber goes on-hook, a disconnection signal is sent to the called party, the called party hears the business tone, and if the called party goes on-hook, recovery is completed. Send a signal to the originating side. On the other hand, at the time of destination call, when the called subscriber goes on-hook, an interruption signal is sent to the calling party, the calling party hears the business tone, and if the calling party goes on-hook, Send a disconnection signal to the receiving side. The destination side returns a restoration completion signal to the calling side. The billing information signal and the billing response signal are transmitted / received in the disconnection process sequence when the billing signal request flag is indicated in the subscriber data inquiry response signal, that is, when the incoming billing is requested. Is shown. This request is controlled by the charging unit 206 of the service control device 200.

FIG. 12 and FIG. 13 are sequence charts showing another embodiment of the present invention. In the case where there are a plurality of callees, a procedure for allowing the caller to select a dialed number for the callee is shown. Shows. In this case, for example, the service file 201 of the service control device 200
This can be realized by preparing a service menu for selecting a number as the service condition. For the guidance method and the like, the conventional method can be used as it is. That is, the calling subscriber goes off-hook and dials the dial number, whereby the address signal is sent to the relay exchange apparatus 100. By transmitting a subscriber data inquiry signal from the repeater exchange device 100 to the service control device 200, the subscriber control device 200 sends the subscriber data to the calling subscriber via the relay exchange device 100.
Send back the inquiry response signal. When the guidance (for selection) is sent from the relay exchange apparatus 100 to the calling subscriber, the calling subscriber selects a numeral, and the selected numeral is returned to the relay switching apparatus 100. Next, the guidance (for confirmation) is sent from the relay exchange apparatus 100 to the calling subscriber. The calling subscriber returns the selected number to the repeater exchange apparatus 100 again. At the time of calling to the destination, the calling subscriber goes on-hook to send a disconnection signal to the repeater switching device 100. When a billing response signal is received from the service control device 200, a restoration completion signal is returned to the calling subscriber. To be done. At the time of first-arriving, when the called-side subscriber goes on-hook, an interruption signal is sent to the calling-side subscriber through the transit switching device 100, and the calling-side subscriber hears the business tone. When the switch is on-hook, a disconnection signal is sent to the repeater exchange device 100, and then a recovery completion signal is returned from the repeater exchange device 100 to the calling subscriber.

FIG. 4, FIG. 5 and FIG. 6 are state transition diagrams when the relay exchange apparatus of the present invention makes simultaneous incoming calls to a plurality of incoming call destinations. In the figure, the title of each status block (empty, inquired, etc.) indicates one state of the device, and in the figure, the switch section in the device and the connection control state between the trunks via the switches are shown. . First, when the incoming signal is received by the incoming trunk while the switching device is in the empty state 11, the switching device captures the trunk for the service control device through the switch section, and the service control device 20
Communicate with 0. The exchange apparatus enters the inquiry state 12 by sending a subscriber data inquiry signal to the service control apparatus 200. The * 1 trunk is a virtual memory trunk used for exchanging information with the service control device 200. Service control device 20
When a subscriber data inquiry response signal is received from 0,
There are a calling state 13 (see claim 2) and a calling state 15 (see claim 3). First, in the calling state 13, after capturing the corresponding outgoing trunk, the path (dotted line) from each outgoing trunk to the incoming trunk is reserved, and then each trunk is put into the calling state and the ringback tone ( RBT) is returned. When the first response signal is received, the call state 14 is entered. In the call state 14, the corresponding outgoing trunk and incoming trunk are put into a calling state, the actual path is connected, and the other outgoing trunks are released. In the call state 15,
The incoming trunk is once connected to a special trunk in which a plurality of outgoing trunks and real paths can be set, and the outgoing trunk is put into a calling state via the special trunk. Then, the trunk for the service control device is released. Next, when the first response signal is received, the call state 16 is entered. In the call state 16, the corresponding outgoing trunk, incoming trunk, and special trunk are put into a calling state. Other exit trunks are released.

The above is the description of the operation sequence of the repeater exchange apparatus 100. The service conditions registered in the service control device 200 can be easily changed by each subscriber. When changing the service conditions, the subscriber dials a special number for changing the service conditions, or the subscriber declares the service conditions to the station,
It is realized by a method such as changing by the maintenance person based on the declaration. The present invention can use either method. When the relay exchange apparatus 100 receives the connection destination change request information by direct dialing from the subscriber, for example, the relay exchange apparatus 10
The information transfer unit 104 in 0 transfers the information to the service control device 200. The service changing unit 204 of the service control device 200 changes the service user file 201 according to the received information. In this way, signals transmitted and received between the respective devices may be transmitted in a designated format via, for example, the common line signal network. Further, when the service condition is changed, it can be easily realized by instructing an input method using a normal guidance function.

[0014]

As described above, according to the present invention,
Since it is possible to reach a plurality of numbers on the called side by one call, the called party can change the called party wherever it is. Also, a subscriber who has a lot of opportunities to move will not miss an incoming call as long as he / she is near the telephone having the number registered as the destination.
