Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mass call receiving method and system for a specific number call connection service of an intelligent network.

[0002]

2. Description of the Related Art Conventionally, in an intelligent network composed of a subscriber switching center (including a service access point (SAP)), a service control station (NSP), a service control general control station (NSSP) and a common line signaling network. There is a line connection service that allows you to connect to multiple telephone lines with a single telephone number, such as a free-dial service or a navigation dial service, a so-called specific number call connection service. It was possible to receive all the calls from the persons at the same telephone number at the same time and provide various services such as information provision.

[0003]

However, in the above-mentioned conventional specific number call connection service, when more calls than the number of contracted reception lines occur at the same time, an "overflow call", that is, an invalid call (BT connection) occurs in the network. Therefore, there was a problem that the opportunity to acquire the user (customer) who made the call was lost. Of course, it is possible to reduce such invalid calls by increasing the number of reception lines, but it is necessary to install additional equipment such as telephones for reception, and the contract fee with the telecommunications carrier also rises accordingly. There was a problem.

An object of the present invention is to have a network (communication carrier) once accept calls for more calls than the number of reception lines, which has hitherto been a flood call, and to store calling telephone numbers. It is intended to provide a mass call reception method and a system thereof that enable a return call.

[0005]

According to the present invention, in order to achieve the above object, a specific number call connection service in an intelligent network composed of a subscriber switching center, a service control station, a service control control station and a common line signaling network. In the above, the idle state of the telephone line for the specific number call connection is judged. If there is no free line, it is judged whether it is a calling ID notification call. If it is a calling ID notification call, the reception guidance is given to the called telephone line. delivery, then the processing information corresponding to the originating ID storage accumulate over accumulates outgoing ID, outgoing I
D If the call is not a notification call, determine the reason for non notification and perform caller operation
If it is not notified by
Non-delivery requesting and notifying that the calling ID will be stored
We propose a method for receiving a large number of calls that sends guidance for acquaintances .

According to the present invention, when a user makes a call with a notification of the ID to a specific number where the reception line is all busy, a guidance for making a call back is sent and the call is made. Since the IDs are stored, the business operator having the specific number can call back the user who could not connect, and the number of customer acquisition opportunities can be increased without increasing the number of reception lines.

Further, according to the present invention, in the intelligent network which is composed of a subscriber switching center, a service control station, a service control controlling station and a common line signaling network and performs a specific number call connection, a calling ID is given to the subscriber switching center. At least one of a means for transmitting / receiving and a means for transmitting guidance or a sound source device for guidance transmission is provided, and a service control station is provided with means for identifying a transmission ID and means for controlling guidance transmission, and for the service control station. , Means for accumulating caller ID and its processing information are provided,
The subscriber switching center is connected to the control terminal for collecting the call origination ID and the processing information accumulated in the service control central office ,
Furthermore, is the calling ID identification means a calling ID notification call?
It is judged whether or not it is a non-notification reason if it is not the outgoing ID notification call
And the guidance control means sends the non-notification reason.
In case of operator's operation, caller ID notification to the guidance sending means
Request to re-distribute by and store caller ID
We propose a mass call reception system that sends out a guidance for non-notifiers .

According to the present invention, when the user accommodated in the subscriber exchange sends a call to the specified number whose reception line is all busy with the notification of the ID by the sending ID sending / receiving means, the The ID is identified by the transmission ID identification means of the service control station, the guidance transmission means or the sound source device is driven by the guidance transmission control means, and the guidance for making a call back is transmitted, and the transmission is transmitted to the storage means of the service control station. Since the IDs are stored, the business operator having the specific number can call back the user who could not connect, and the number of customer acquisition opportunities can be increased without increasing the number of reception lines.

Is sent. It should be noted that the sound source device 63 and the guidance sending means 23 can be installed in combination with each other, or only one of them can be installed (however, one sound source device has only one guidance. Since it cannot be held, it is necessary to install multiple sound source devices that hold each guidance when sending multiple guidances.) Further, the guidance sending means 23 is not limited to being provided in the subscriber switching center 20, but may be installed in the subscriber switching center (including SAP) 10.

Further, the call connection instructing means 31 determines whether or not the connection destination telephone line corresponding to the specific number transmitted from the transmission ID transmitting / receiving means 11 and 21 is in the open / closed state, and calls the subscriber exchange stations 10 and 20. Make a connection instruction. The calling ID identifying means 32 identifies whether the calling ID information transmitted from the calling ID transmitting / receiving means 11 and 21 is a calling ID notifying call or a calling ID non-notifying call. The guidance control means 33 controls guidance transmission based on the identification result of the transmission ID identification means 32.

The storage means 41 stores the transmission ID and the processing information thereof.

FIG. 2 is a control flow chart in this system, and the operation of this system will be described in detail based on this.

A specific number (for example, 0AB0-*****) is transmitted from the caller's telephone 61 (step s).
1) and the specific number are received by the subscriber switching center 10 via the subscriber line 71 (step s2). In the transmission ID transmitting / receiving means 11, the specific number and the telephone number of the sender (hereinafter,
It is called "Calling ID". ) Or, the caller ID non-notification reason information is sent to the control station 30 via the common line signaling network 50 (step s3).

The caller ID non-notification reason information is in advance of the caller's operation (for example, dialing a number indicating refusal of notification before dialing a specific number) or constant non-notification information to the subscriber exchange. Notification refusal information due to registration (hereinafter referred to as "P (Privacy)") and notification refusal information due to calling from a public telephone (hereinafter referred to as "C (Coin & Card T
ele-phone) ". ) And notification refusal information due to the circumstances of the network side originating from an analog exchange (hereinafter, “O
(Out of Area) ". ) And three.

The call connection instructing means 31 confirms the idle state of the connection destination line from the received specific number (step s).
4). 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 the line (not shown) and the control which representatively set the subscriber line 72 in the subscriber exchange 20. It also includes a line (not shown) preset as a transfer destination of the subscriber line 72 in the station 30.

As a result of the confirmation in step s4, if there is a free line (step s4: N), the call connection instructing means 3
The call connection processing means 12 makes a line connection to the connection destination line according to the instruction No. 1, that is, the caller's telephone 61 and the callee's telephone 6
2 is connected to the line (step s5).

As a result of the confirmation in step s4, if there is no available line (step s4: Y), the guidance control means 33 determines whether the guidance sending function is in operation (step s6). The start and stop of the guidance sending function is performed by the control terminal 64 connected to the control control station 40.
Can be arbitrarily set and changed.

If the result of determination in step s6 is that it is not active (step s6: N), call connection instructing means 31
In response to the instruction, the call connection processing means 12 sends a busy tone (step s7). On the other hand, when the call is being started (step s6: Y), the caller ID identifying unit 32 identifies the caller ID or caller ID non-notification reason information received from the caller ID transmitting / receiving unit 11 to determine whether the call is a caller ID notification call. Is determined (step s8).

As a result of the judgment in step s8, the transmission I
When the call is not the D notification call (step s8: N), the calling ID identification means 32 determines the reason for non notification (step s).
9). As a result of the judgment, when the reason for non notification is other than P (Privacy) (step s9: N), that is, C (Coin & Card Tele-
phone) or O (Out of Area), the busy tone is transmitted (step s7).

Further, as a result of the judgment in step s8,
If the call is an outgoing ID notification call (step s8: Y) or as a result of the determination in step s9, the reason for non notification is P (Priv
acy) (step s9: Y), the accumulating unit 4
It is determined whether the number of caller IDs stored in the control station 40 is within the upper limit (1) (step s10). The upper limit value can be arbitrarily set and changed by the control terminal 64 connected to the control control station 40.

As a result of the judgment in step s10, if the number of accumulated outgoing IDs is not within the upper limit value (step s10:
N) confirms whether "overflow guidance" is registered in the guidance sending means 23 by the guidance control means 33 (step s11). As a result of the confirmation in step s11, if the "overflow guidance" is not registered (step s11: N), the busy tone is transmitted (step s7).

If the "overflow guidance" is registered (step s11: Y), it is determined whether the call is an outgoing ID notification call (step s12). If it is not the outgoing ID notification call (step s12: N), That is, the reason for non notification is P
If it is (Privacy), the busy tone is transmitted (step s7). On the other hand, if the call is an outgoing ID notification call (step s
12: Y) sends the "overflow guidance" registered in the guidance sending means 23 according to an instruction from the guidance control means 33 (step s13).

The "overflow guidance" referred to here is a guidance for notifying that a call connection is impossible and a redial request is made. For example, "Thank you for calling. Click here." Is ○○. It is crowded right now, so please wait for a while and try again. " It should be noted that XX in the guidance can send any information such as the telephone number and name of the called party.

As a result of the judgment in step s10, if the number of accumulated outgoing IDs is within the upper limit value (step s10:
Y) determines whether the call is a calling ID notification call (step s14). If it is not the outgoing ID notification call (step s1)
4: N), that is, when the reason for non-notification is P (Privacy), it is confirmed whether or not "guidance for non-notifier" is registered in the guidance sending means 23 (step s15).
When the "non-notifier guidance" is not registered (step s15: N), the busy tone is transmitted (step s).
7) If the "non-notifier guidance" is registered (step s15: Y), the "non-notifier guidance" registered in the guidance sending means 23 is sent (step s16).

The "non-notifier's guidance" referred to here is a guidance for requesting re-calling by calling ID notification and notifying that the calling ID is to be accumulated. The phone is busy right now, but if you notify us of your phone number and call back, you can record your phone number to the other party. "

If the result of determination in step s14 is that the call is an outgoing ID notification call (step s14: Y), the guidance sending means 2 is instructed by the guidance control means 33.
3 or the "reception guidance" registered in the sound source device 63 is transmitted (step s17), and then the accumulating unit 4
In step 1, the transmission ID is stored in the control station 40 and the transmission end time of the "reception guidance" is stored (step s18).

The "reception guidance" mentioned here is a guidance for notifying that the call connection is impossible and the calling ID is registered. For example, "Thank you for calling. Is ○○. I have registered my phone number, so I will contact you later. " It should be noted that XX in the guidance can send arbitrary information such as the telephone number and name of the called party, as in the case of the "overflow guidance".

Although not shown in FIG. 1, the subscriber switching center 10 is provided with a subscriber switching center 20 (or is equipped with a guidance transmitting means, or a sound source device) when the line is connected to the called party or when the guidance is transmitted. It is needless to say that it is connected via a normal telephone line to another subscriber exchange station that accommodates the Except when it is the subscriber exchange station 10 itself).

As described above, the call connection cannot be established and the call origination ID and the "reception guidance" stored in the control station 40 are stored.
Regarding the transmission end time, the called party collects information from the control terminal 64 via the common line signaling network 50, and based on the information, makes a return line connection to the calling party. The control station 4
The calling ID and the “reception guidance” transmission end time accumulated in 0 can be deleted by the control of the control terminal 64.

The number of caller IDs that can be stored in the storage means 41 is determined for each called party (contractor) in advance (usually at the time of contract). For example, as shown in FIG. Will be stored as BOX size 42 in
It is necessary to manage the number of connections to the reception guidance (the number of notification of the transmission ID to the control station 40) so as not to exceed the size (the number of accumulations).

Therefore, as shown in FIG. 3, an upper limit value (holding means) 34 of the number that can be stored (notified) by the control station 40 in the control station 30 and a counter of the number of stored (notified) transmission IDs. 35 is held for each contractor, and when the counter 35 exceeds the upper limit 34, the reception guidance connection is not made,
"Overflow guidance" connection or BT connection. However, it is assumed that the ID notification number upper limit 34 can be arbitrarily set within the BOX size 42 that can be stored by the contractor according to an instruction from the control terminal 64.

At this time, when the number of accumulated outgoing call IDs reaches the upper limit value, the notification of outgoing call IDs is stopped. However, by deleting the outgoing call IDs accumulated by the instruction of the control terminal 64, notification of a new outgoing call ID ( Accumulation) is possible.

As a method of deleting the stored caller ID,
There are two types of "inquired ID deletion" and "all ID deletion". That is, the control terminal 64 is used for the "inquired ID deletion".
Only the calling ID inquired by is deleted, and the counter 35 is decremented by the instruction of the control station 40. Also, "All IDs
"Delete" deletes all the stored caller IDs, and initializes (clears) the counter 35 according to an instruction from the control station 40 (however, for "delete all IDs", the counter 35 is unmatched. Only possible while stopped.).

Next, a concrete operation when the free dial service or the navigation dial service is carried out by using the system of the present invention described above will be described.
