SOLUTION: When a call is generated from a user 61 when all the receiving lines of a company 62 contracting the specific number call connection service are busy, a guidance control means 33 sends a guidance to the effect of queue- connecting from a guidance sending means 12 and the call is registered to the queuing register means 32 of a control station 30 to line-connect the user 61 and the company 62 when a dead line for receiving is generated within a prescribed time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a queuing connection system in a specific number call connection service of an intelligent network.

[0002]

2. Description of the Related Art Conventionally, in an intelligent network constituted by a local exchange (including a service access point (SAP)), a service control station (NSP), a service control supervision station (NSSP) and a common channel signaling network. There is a line connection service such as a toll-free service or a navi-dial service, which can connect to a plurality of telephone lines with one telephone number, a so-called specific number call connection service. It was possible to simultaneously receive all the telephone calls from the user with the one telephone number and provide various services such as information provision.

[0003]

However, in the above-mentioned conventional specific number call connection service, when a number of calls equal to or greater than the number of contracted reception lines occur simultaneously, an "overflow call", that is, an invalid call (BT connection) is made in the network. As a result, there is a problem that the opportunity to acquire the user (customer) who made the call is lost. Of course, if the number of reception lines is increased, it is possible to reduce such invalid calls, but it is necessary to increase the number of receiving telephones and other equipment, and the contract fee with the telecommunications carrier rises accordingly. There was a problem.

An object of the present invention is to have a network (telecommunications carrier) wait for a call exceeding the number of lines for reception, which has conventionally been an overflow call, and for the line for reception to be available within a predetermined time. In such a case, it is an object of the present invention to provide a queuing connection method that enables the user to be connected.

[0005]

In order to achieve the above object, the present invention provides a specific number call connection service in an intelligent network composed of a local exchange, a service control station, a service control control station, and a common channel signaling network. Then, the idle state of the telephone line of the specific number call connection is determined, and if there is no free line, the waiting guidance is transmitted to the destination telephone line and held, and thereafter, an idle line is generated within a predetermined time. In such a case, a queuing connection method is proposed in which the destination telephone line is connected to the empty line, and if not, the destination telephone line is disconnected.

According to the present invention, when a user makes a call to a specific number in which all reception lines are busy, a guidance to the effect that a queuing connection is made is transmitted, and the queuing time is measured. If the reception line becomes available, the line will be connected, so that the operator with the specific number can wait for a user who cannot connect to the line, and increase the chance of acquiring customers without increasing the number of reception lines. be able to.

FIG. 1 is a system configuration diagram showing an example of an embodiment of the present invention. In the figure, reference numerals 10 and 20 denote subscriber exchanges (including a service access point (SAP)) and 30. Is a service control station (NSP), 40 is a service control supervision station (NSSP), 50 is a common channel signaling network, 6
Reference numerals 1 and 62 are telephones and 63 is a control terminal.

[0008] The local exchange 10 accommodates a user, that is, a telephone set 61 of a caller via a subscriber line 71, and includes a call connection processing means 11, a guidance sending means 12, and a timer means 13. I have. Also, the local exchange 20
The telephone connection processing means 2 accommodates a service provider, that is, a receiver's telephone set 62 via a subscriber line 72 and a control terminal 63 via a subscriber line 73.
1 is provided.

The service control station 30 controls call processing of a specific number transmitted from a caller, and includes a call connection instructing means 31, a queuing registration means 32, and a guidance control means 33.
It has. The service control supervising station 40 processes call processing information of a specific number, and downloads data (specific number, waiting number upper limit value, etc.) relating to a service provider who has made a queuing connection contract to the service control station 30.

The local exchanges 10 and 20 and the control station 30 are connected to a common channel signaling network 50 via control lines 81, 82 and 83 for mutually transmitting and receiving control signals for information transmission. The control station 30 and the control control station 40 are connected via a line 84 for transmitting and receiving information signals.

The control terminal 63 is connected to the control supervising station 40, and sets and changes the upper limit of the number of waiting times registered in the control station 30 via the control terminal 63.

The telephone 62 and the control terminal 63 of the called party
Can be accommodated in different local exchanges, and are not limited to those accommodated in the same local exchange.

Here, the call connection processing means 11 and 21 transmit and receive call information such as a specific number transmitted from the telephones 61 and 62, respectively, and perform call connection, transmission of a busy tone, etc. according to an instruction of the call connection instruction means 31. I do. Further, the guidance transmitting unit 12 transmits a plurality of guidances prepared in advance, that is, “waiting guidance” or “cutting guidance” according to the instruction information transmitted from the guidance control unit 33. The guidance sending means 12 is not limited to being provided in the local exchange 10 (including the SAP), but may be provided in the local exchange 20. Further, the timer means 13 counts the elapsed time after the registration for each registered call.

The call connection instructing means 31 determines whether the connection destination telephone line corresponding to the specific number transmitted from the call connection processing means 11 or 21 is idle or not, and
And 20 are instructed for call connection. Further, the queuing registration means 32 performs queuing registration / deletion of a call for the specific number transmitted from the call connection processing means 11 and 21. Further, the guidance control unit 33 controls the guidance transmission based on the operation of the waiting registration unit 32.

FIG. 2 is a control flowchart in the present system. Hereinafter, the operation of the present system will be described in detail based on the flowchart.

A specific number (for example, 0AB0-****) is transmitted from the caller's telephone 61 (step s).
1), the specific number is received by the local exchange 10 via the subscriber line 71, and transmitted from the call connection processing means 11 to the control station 30 via the common line signaling network 50 (step s).
2).

The call connection instructing means 31 confirms the idle / busy state of the connection destination line from the received specific number (step s).
3). The connection destination line referred to here is not only the subscriber line 72 connected to the telephone set 62 of the called party, but also a line (not shown) representatively setting the subscriber line 72 in the local exchange 20 and control. A line (not shown) set in advance as a transfer destination of the subscriber line 72 by the station 30 is also included.

As a result of the check in step s3, if there is a free line (step s3: N), the call connection instructing means 3
1, the call connection processing means 11 makes a line connection with the connection destination line, that is, the caller's telephone 61 and the receiver's telephone 6
2 is connected to the line (step s4).

As a result of the check in step s3, if there is no free line or if there is a call registered for waiting (step s3: Y), it is determined whether the number of registered waiting calls is within the upper limit. (Step s
5). The upper limit can be arbitrarily set and changed by the control terminal 63 connected to the control control station 40.

If the result of determination in step s5 is that the number of registered registrations is not within the upper limit (step s5: N),
In response to the instruction from the call connection instructing means 31, the call connection processing means 11 transmits a busy tone (step s6).

If the result of determination in step s5 is that the number of registered registrations is within the upper limit (step s5: Y)
Performs the waiting registration by the waiting registration means 32 (step s7), and sends out the "waiting guidance" registered in the guidance sending means 12 according to the instruction of the guidance control means 33 (step s8).

The "waiting guidance" referred to here is a guidance for notifying that a call connection is currently impossible and a waiting connection is to be made. For example, "This is OO, , It's busy now. We will accept it as soon as it is available, so please wait as it is. The waiting time is up to x minutes (1 to 5 minutes). " Note that XX in the guidance enables transmission of arbitrary information such as the telephone number and name of the called party.

The registered waiting call is counted by the timer means 13 to determine whether or not a predetermined waiting time has elapsed (step s9), and to determine whether or not the connection destination line is free. Is determined (step s
10).

If there is a free space in the connection destination line within the waiting time (steps s9: N, s10: Y), the call connection processing means 11 makes a line connection with the connection destination line according to the instruction of the call connection instruction means 31. That is, the caller's telephone 61 and the receiver's telephone 72 are line-connected (steps s11, 1).
Along with 2), the registration of the corresponding waiting call is deleted by the waiting registration means 32 (step s13).

As a result of the determination in step s9, if there is no free space in the connection destination line even after the predetermined waiting time has elapsed (step s9: Y), the connection is registered in the guidance sending means 12 according to the instruction of the guidance control means 33. The "disconnection guidance" is sent (step s14), the line with the caller is disconnected (step s15), and the registration of the corresponding waiting call is deleted by the waiting registration means 32 (step s13).

The "disconnection guidance" referred to here is a guidance for notifying that a line currently in a waiting connection will be disconnected. For example, a message such as "I waited for a while, It's going to take some time yet. I'm sorry, but I'll cut it off. Please be patient. "

Although not shown in FIG. 1, when a line is connected to a called party or when guidance is transmitted, the local exchange 10 switches the local exchange 20 (or another subscriber provided with guidance transmitting means). It is needless to say that the local exchange is connected to the local exchange via a normal telephone line (however, another local exchange having guidance sending means is connected to the local exchange 10).
Unless it is itself. ).

The number of calls that can be registered in the queuing registration means 32 is determined in advance for each called party (contractor). For example, as shown in FIG. The value is held as (holding means) 34. At this time, it is necessary to manage the number of connections to the queuing guidance (the number of queuing connections) so as not to exceed the upper limit value. Therefore, as shown in FIG. And the counter 3
If 5 exceeds the upper limit 34, the BT connection is not performed instead of the waiting guidance connection. However, the waiting number upper limit value 34
Can be arbitrarily set by the contractor in accordance with an instruction from the control terminal 63 connected to the control control station 40. Also, the waiting time can be arbitrarily set according to an instruction from the control terminal 63 connected to the control control station 40. Next, a specific operation when the above-described system of the present invention is used in a free dial service or a navigation dial service will be described.

FIG. 4 shows waiting guidance transmission when the operator's line can be confirmed to be all busy only by NSP access, in this case, SAP (service access point)
1 shows how a guidance transmission unit (not shown) mounted on the system transmits a waiting guidance.

(1) The user (caller) dials the specific number "0AB0-D ~ J" of the business operator, (2) performs NSP (service control station) access, (3) the operator's line If the call is busy or the NSP already has a waiting call, register the waiting and instruct the SAP to wait. (4) Send the waiting guidance to the caller (after that, send BGM if necessary) and wait for the waiting. Do.

FIG. 5 shows waiting guidance transmission in the case where it is not possible to confirm that the line of the business operator is busy during NSP access only, in this case, guidance transmission means (not shown) mounted on an SAP (service access point). FIG. 7 shows how to send a waiting guidance.

(1) The user (caller) dials the specific number "0AB0-DJ" of the business operator, (2) Performs NSP (service control station) access, (3) NSP vacancy management If there is a free space, notify the SAP of the connection destination physical number,
(4) Connect using the connection destination physical number; (5) Return all SAP busy to the SAP when the operator's line is busy at the destination exchange.
(6) NSP that SAP could not connect due to busy
(7) If there is no other place to be connected in the NSP, register the waiting and instruct the SAP to wait. (8) Send the waiting guidance to the caller (if necessary, then use the BGM Is sent out) and a meeting is performed.

FIG. 6 shows how a waiting call is connected.

(0) Sending BGM (Guidance) During Waiting (1) NSP (Service Control Station) issues an instruction to connect a waiting call in response to the following trigger, such as a call termination notification from SAP.
Instructs the AP.-When the NSP idle / busy management becomes free from busy, instructs the connection of a call that is already waiting.-A new call when a call that is already waiting is registered at the NSP. Is issued, a connection instruction for a call already waiting is issued. However, the condition of the connection instruction to the operator of the waiting call is when there is a vacancy in the management of the NSP, and when there is no space in the management of the vacancy, the connection instruction is not performed. If the call that instructed the connection to the party was notified from the SAP that the connection was successful,
Next, a connection instruction for the waiting call is issued. However,
The condition of the connection instruction to the operator of the waiting call is that the NSP has an empty space management, and if there is no empty space management, no connection instruction is given. (2) SAP is BGM (Guidance) (3) Returns the connection result, (4) SAP performs the following operations based on the connection result, and notifies the NSP of the connection result. In such a case, stop sending the BGM (or guidance) and connect the caller and the called party. ・ If the called party is busy or becomes congested at the relay node, leave the BGM (or guidance) sent.
(5) The NSP performs the following operations according to the connection result.-When the operator answers, deletes from the waiting state management (instructs the SAP to connect the next waiting call to the SAP). (6) The SAP manages the timer for the set waiting time. If the waiting time is exceeded, the SAP gives the caller a guidance to the effect that a timeout has occurred. Send and disconnect the line with the caller. Further, the SAP notifies the NSP of the disconnection, and the NSP deletes the corresponding waiting call from the waiting state management.

[0035]

As described above, according to the present invention,
When the user makes a call to a specific number where the reception line is all busy, the user is notified of the waiting connection and the waiting time is measured, and if the reception line becomes available within the predetermined time, Because of the line connection, the contracted operator of the specific number call connection service can make a user who cannot connect to the line stand by, thereby increasing opportunities for acquiring customers without increasing the number of reception lines.
