In the following detailed description of the preferred embodiments of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In the drawings, like reference numerals are used throughout the drawings.

In addition, in the entire specification, when a part is referred to as being 'connected' to another part, it may be referred to as 'indirectly connected' not only with 'directly connected' . Also, to "include" an element means that it may include other elements, rather than excluding other elements, unless specifically stated otherwise.

1 is a schematic diagram showing an intelligent network interworking call service system according to an embodiment of the present invention.

Referring to FIG. 1, an intelligent network interworking communication service system according to an embodiment of the present invention includes a service control point (SCP) 100, a service switching point (SSP) 10, a service database SDP A Service Database Point 20, a No. 7 signaling network 30, a local exchange 40, an originating terminal 1 and a terminating terminal 2. [

The intelligent network interworking call service system can provide the call service using the prepaid card. A prepaid card-based call service is a service that enables a card, a public telephone, or a mobile phone terminal to be assigned a card number of a prepaid card, , The usage fee of the call service may be paid in a manner that subtracts the amount charged to the prepaid card. However, according to the embodiment, instead of subtracting the charged amount, it is also possible to accumulate the usage fees used for a certain period of time, and charge the user to the usage fee on the predetermined settlement days. That is, the intelligent network interworking communication service system according to an embodiment of the present invention can provide a call service using a deferred charge card, which accumulates usage charges for a certain period of time and charges the settlement date. Here, since the call service using the prepaid card and the call service using the deferred card differ only at the time of payment of the usage fee, the following description assumes that the content of the call service using the deferred card is included in the call service using the prepaid card do.

The calling party can input the connection number to the calling terminal 1 and the local exchange 40 can collect the connection number inputted by the calling terminal 1 in order to receive the calling service using the prepaid card. Thereafter, the local exchange 40 may call the service switching exchange 10 via the No. 7 signaling network 30.

The service switching exchange 10 may call the service control switching center 100 to activate the call service corresponding to the access number. Here, the service control switching center 100 can provide different call services according to the connection number inputted by the calling terminal 1. [ Thereafter, the service control switching center 100 may request the service switching exchange 10 to collect the caller's prepaid card card number, destination number, etc. in order to provide the call service.

The service switching exchange 10 can transmit the card number input announcement broadcast using the predetermined call route and the caller who listens to the card number input announcement broadcast through the calling terminal 1 can receive the card of the prepaid card It is possible to input the number to the calling terminal 1. The card number input to the calling terminal 1 can be input to the service switching center 10 through the local exchange 40 and the No. 7 signaling network 30. [ Thereafter, the service switching exchange 10 can transmit the collected card number to the service control exchange 100, and the service control switching center 100 can exchange the prepaid card corresponding to the card number in the service database 20, Storage device. If the balance remains on the prepaid card as a result of the inquiry, and the normal state is found in which there is no theft or lost notification, the service controlling exchange 100 may request the service switching exchange 10 to collect the called number.

In this case, the service switching exchange 10 can broadcast the called party number input announcement broadcast to the calling terminal 1 together with the announcement of the inquiry result such as the balance using the preset call channel. Thereafter, the caller can input the called number corresponding to the called terminal 2 to which the call connection is to be performed in response to the incoming number input announcement broadcast, and the called number is inputted to the local exchange 40, 30 and the service switching exchange 10 to the service controlling exchange 100. [

The service control switching center 100 having received the called number can generate call data so that the call service between the calling terminal 1 and the called terminal 2 is connected using the called number, To the exchange 10. Thereafter, the service switching exchange 10 can provide a call service by making a call connection between the calling terminal 1 and the called terminal 2 using the received call data. Here, according to the embodiment, the service control switching center 100 can inquire the called number to a storage device in the service database 20 or the like to determine the connection of the call service, and only when the inquiry result is available , It is possible to generate the call data. Meanwhile, a call path can be connected between the calling terminal 1 and the called terminal 2 by the service switching exchange 10, and when the calling terminal 1 or the called terminal 2 terminates the call or the balance is exhausted The provision of the call service may be discontinued.

However, there is a problem in that it is difficult to provide various kinds of call services and the like when distinguishing the types of call services using only the connection numbers. For example, if you want to provide different types of call services such as different rates for different countries, different rates for different time zones, etc., you can set up a different access number for each country or type of call service. There is a problem such as an increase in cost due to the establishment of a connection number and waste of resources, and there may be inconvenience in terms of user convenience.

Here, the service control switching center 100 according to an embodiment of the present invention can provide different call services by distinguishing each call according to the card number of the prepaid card. That is, it is possible to distinguish and provide the call service without the addition of an additional connection number, so that it is possible to prevent an increase in cost and waste of resources due to the establishment of the connection number and the like.

Hereinafter, with reference to FIG. 2, a service control switching center 100 according to an embodiment of the present invention will be described.

2, the service control switching center 100 according to an embodiment of the present invention includes a service connection unit 110, a parameter collection unit 120, a routing generation unit 130, a call data generation unit 140, A buffer unit 150, an error processing unit 160, and the like.

First, the service connection unit 110 can receive a call service request of the calling terminal 1 from the service switching center 10. That is, when the calling terminal 1 enters the connection number, a call service request is input to the service switching center 10 through the local exchange 40. The service switching center 10 notifies the service connection unit 110 of the call A service request can be transmitted. Here, the service connection unit 110 receiving the call service request activates the control of the service control exchange 100 to process the call service request of the calling terminal 1. [

The parameter collecting unit 120 can collect the card number of the prepaid card inputted by the calling terminal 1 and the called number corresponding to the called terminal 2 to which the calling terminal 1 is to make a call connection. Here, the parameter collecting unit 120 may request the collection of the prepaid card number to the service switching exchange 10. That is, according to a request from the parameter collecting unit 120, the service switching exchange 10 can transmit a card number input announcement broadcast to the calling terminal 1 on a predetermined call basis, It is possible to input the card number of the prepaid card to the calling terminal 1. [ In this case, the service switching exchange 10 may receive an IAM (Initial Address Message) message including the card number through the local exchange 40 and the No. 7 signaling network 30. The service control switching center 100 can receive the IAM message including the card number from the service switching center 10, so that it can extract the card number from the IAM message.

In addition, the parameter collecting unit 120 can search for a balance or an accumulated usage amount corresponding to the received card number, and can determine whether or not the prepaid card can be used through the search result. For example, if the balance remaining on the prepaid card is equal to or greater than the predetermined minimum amount or the cumulative use amount is less than the predetermined maximum amount, it can be determined to be usable. In particular, in the case of a call service using a deferred payment card, it is possible to determine whether or not the deferred payment card can be used by checking whether the cumulative amount exceeds a predetermined maximum amount. In addition, depending on the embodiment, it is also possible to check whether the prepaid card is stolen, lost or not, and whether there is a payment stop request, in addition to the remaining amount corresponding to the card number or the cumulative amount of money. On the other hand, if it is determined that the prepaid card is usable, the parameter collecting unit 120 may request the service switching center 10 to transmit the called party number input announcement broadcast and collect the called number. Here, the collecting method of the called number is the same as the collecting method of the card number, so a detailed explanation will be omitted.

The routing generation unit 130 may set a routing identifier corresponding to the collected card number, and may add the set routing identifier to the called number. Specifically, the routing generation unit 130 may convert the card number into a decimal number, and may set a routing identifier corresponding to the group including the converted decimal number as the routing identifier of the card number. That is, the number of decimal digits corresponding to the number of digits of the card number can be set in advance as a plurality of groups by dividing the range, and the routing delimiter corresponding to each group can be set in advance. Therefore, after comparing the size of the decimal number corresponding to the card number, searching for a group having a range including the converted decimal number, and comparing the routing identifier corresponding to the retrieved group with the routing identifier of the card number . For example, 12 numbers 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2 and 3 may be sequentially input to the card number, You can convert the card number to the decimal number 234567890123. Here, a first group including 230000000000 to 239999999999, a second group including 240000000000 to 249999999999, and a third group including 250000000000 to 259999999999 may be preset. In addition, the first group of routing delimiters may be set to 100, the second group of routing delimiters may be set to 200, and the third group of routing delimiters may be set to 300, respectively. Therefore, when the size of the converted 234567890123 is compared with each of the groups, it can be determined that the converted group is included in the first group, and the routing identifier 100 corresponding to the first group can be set for the card number 234567890123. In the case where 2, 5, 1, 2, 3, 4, 5, 6, 7, 8, 9 and 0 are inputted as the card number, 251234567890, which is the number of decimal notation, , It is possible to set 300 as a routing delimiter.

Thereafter, the routing generator 130 may add the routing identifier set to the called number, and may be included in the form of a prefix before the called number. For example, if the called number is 01033335555, the routing identifier 100 can be added to generate 100-01033335555.

The call data generating unit 140 may generate call data including the called party number to which the routing identifier is added and transmit the generated call data to the service switching center 10. That is, it is possible to generate call data for connecting a call service between the calling terminal 1 and the called terminal 2, and by transmitting the call data to the service switching center 10, It is possible to connect the call service between the calling terminal 1 and the called terminal 2 by utilizing the call data. Here, since the call data includes the destination number to which the routing delimiter is added, the service switching center 10 having received the call data can distinguish each call using the routing delimiter. Thus, the service switching exchange 10 can connect the calling terminal 1 and the called terminal 2 to provide a corresponding call service for each call.

The buffer unit 150 may perform a function of temporarily storing a card number, a called number, a routing identifier, and the like. That is, the parameter collecting unit 120, the routing generating unit 130, the call data generating unit 140 and the like respectively store the parameters such as the card number, the called number and the routing identifier in the buffer unit 150, The parameter stored in the memory 150 can be called up for utilization.

The error processing unit 160 can perform processing for an error occurring in each configuration included in the service control switching center 100. [ That is, the card number, the call number, and the like extracted by processing or processing performed in the service connection unit 110, the parameter input unit 120, the routing generation unit 130, the call data generation unit 140, the buffer unit 150, , A routing delimiter, etc., does not match the predetermined format, it can be determined that an error has occurred. For example, although the card number is set to a 12-digit number, the card number collected by the parameter collection unit 120 is a 10-digit number, or the routing identifier is a format that is incremented by 100, If the delimiter is set to 101, it can be determined that an error has occurred. Therefore, the error processing unit 160 detects the occurrence of an error such that the format of the parameters such as the card number, the called number, the routing delimiter, etc. does not conform to a predetermined format, and if an error is detected, Specific control can be performed.

On the other hand, the service control switching center 100 according to another embodiment of the present invention can receive a calling number set in advance for the calling party, instead of directly receiving the card number. That is, when the caller first uses the prepaid card using the call service, the calling party can set the card number of the prepaid card and his / her caller's number. Thereafter, when a call service using the prepaid card is used, it is possible to omit the input of a separate card number, and to substitute the input of the card number into the own calling number.

Specifically, the service connection unit 110 can receive a call service request of the calling terminal from the service switching center 10, and the parameter collecting unit 120 collects the calling number input to the calling terminal 1, It is possible to collect the called number corresponding to the called terminal 2 which is connected to the called terminal 2. Thereafter, the routing generating unit 130 may search for a card number corresponding to the collected origination number, and may set a routing identifier corresponding to the searched card number. Here, the card number corresponding to the collected calling number may be stored in advance in the service database 20 or the like. Therefore, the routing generator 130 can find the card number corresponding to the calling number by searching the service database 20, and after setting the routing identifier corresponding to the card number, the routing identifier May be added to the called number. The call data generating unit 140 may generate call data including the called party number to which the routing delimiter is added and transmit the call data to the service switching center 10 and the service switching center 10 may exchange call data including the calling party 1, (2) can provide a call service using the prepaid card.

3 is a flowchart illustrating an intelligent network interworking call service method according to an embodiment of the present invention.

Referring to FIG. 3, an intelligent network interworking call service method according to an embodiment of the present invention includes a service request receiving step S100, a parameter gathering step S200, a routing identifier setting step S300, and a service providing step S400. . ≪ / RTI >

Hereinafter, an intelligent network interworking method according to an embodiment of the present invention will be described with reference to FIG.

In the service request receiving step S100, a service control point (SCP) can receive a call service request from a calling terminal through a service switching point (SSP). That is, when the calling terminal inputs the connection number, a call service request is input to the service switching exchange through the local exchange, and the service switching exchange can transmit the call service request to the service connection. The service control switching center which has received the call service request can activate the control for providing the call service and can process the call service request of the calling terminal.

In the parameter gathering step (S200), the service controlling exchange can collect the card number of the prepaid card from the calling terminal and the called number corresponding to the called terminal to which the call connection is made. Here, the service control switching center may request the service switching exchange for announcement for collection of the prepaid card number, and the caller may input the card number and the called number to be input in response to the announcement.

Specifically, the parameter collecting step S200 includes a card number request step S210, a card number collecting step S220, a destination number requesting step S230 and a destination number collecting step S240, And the called number.

First, in the card number request step (S210), the service control switching center may request the service switching exchange to transmit a card number input announcement broadcast to the calling terminal on a predetermined call route. In this case, the service switching exchange can transmit the card number input announcement broadcast to the calling terminal on the basis of the preset call upon the request of the service control exchange, and the calling party can send the card number input announcement broadcast to the calling terminal, Can be input. Thereafter, the service controlling exchange receives the IAM message including the card number from the service switching exchange, and extracts the IAM message and collects the card number.

In the card number collection step (S220), the service control exchange can search for the balance or accumulated use amount corresponding to the received card number to determine whether or not the prepaid card can be used. For example, if the balance remaining on the prepaid card is equal to or greater than the predetermined minimum amount, it is determined that the card is usable. If the accumulated amount of the post-paid card is less than the preset maximum amount, the card can be used. Depending on the embodiment, in addition to the balance or cumulative amount of money corresponding to the card number, it may further be confirmed whether the prepaid card is stolen, lost or not, and whether there is a payment stop request.

In the called party number request step (S230), the service control switching center can request the service switching exchange to send the called party input announcement broadcast to the calling terminal on the preset call channel. That is, when it is determined that the prepaid card or the like is available in the card number collection step (S220), the caller can collect the called number of the called terminal to which the caller wants to make a call connection. To this end, in the called party number request step (S230), the service control switching center may request the service switching exchange to transmit the called party number input announcement broadcast. In this case, the service switching exchange can transmit the call destination number input announcement broadcast to the calling terminal on the preset call line, and the caller can input the called number to the calling terminal.

Thereafter, in the called party number collecting step (S240), the service controlling exchange may receive the called number from the service switching exchange. That is, the service controlling exchange can receive the IAM message including the called number from the service switching exchange, and collect the called number by extracting the called number from the IAM message.

In the routing delimiter setting step S300, the service controlling exchange can set a routing delimiter corresponding to the collected card number, and add the set routing delimiter to the called number. That is, it is possible to distinguish the connection of the call according to the card number by setting each routing delimiter according to the inputted card number. Specifically, the routing delimiter setting step S300 may include a converting step S310, a searching step S320, and a setting step S330.

First, in the conversion step S310, the card number can be converted into the corresponding decimal number. That is, it is possible to set the attribute of the inputted card number to a decimal number, and to make a size comparison with other numbers. On the other hand, according to the embodiment, it is also possible to extract only the digits of predetermined digits from the inputted card numbers without converting the entire card number into a decimal number, and convert the digits into a decimal number. For example, it is also possible to extract only 1234 corresponding to the first four digits of the card number 123456789012 and convert it to 1234, which is a decimal number.

In the searching step S320, a group having a range including the converted decimal number among a plurality of groups may be searched by comparing the sizes of the converted decimal numbers. For this purpose, it is possible to divide the range of decimal numbers corresponding to the number of digits of the card number into a plurality of groups in advance, and to compare the sizes of the converted decimal numbers corresponding to the card numbers, Group can be searched. For example, when the card number is a 12-digit decimal number, a first group including 230000000000 to 239999999999, a second group including 240000000000 to 249999999999, a third group including 250000000000 to 259999999999, . In this case, when the card numbers 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2 and 3 are sequentially inputted, the first group including the number 23 of decimal numbers 234567890123, As shown in FIG.

In the setting step S330, the routing delimiter corresponding to the searched group can be set as the routing delimiter of the card number. Here, a corresponding routing identifier may be set in advance for each of the groups, and a routing identifier of the group corresponding to the card number may be set as a routing identifier of the card number. For example, the first group of routing delimiters may be set to 100, the second group of routing delimiters may be set to 200, and the third group of routing delimiters may be set to 300. If the card number is 234567890123, The routing delimiter of the card number can be set to 100. In addition, in the setting step S330, the routing identifier of the card number may be added to the called number, and in some embodiments, it may be added in the form of a prefix included before the called number. For example, if the called party number is 01033335555 and the routing identifier is 100, the called party number can be changed to 100-01033335555.

In the service providing step S400, when the service controlling exchange transmits the called number to which the routing identifier is added to the service switching center, the service switching center distinguishes the call according to the routing delimiter, Can be provided. Here, the service controlling exchange may generate call data for connecting a call service between the calling terminal and the called terminal, and the service switching exchange may connect the call service between the calling terminal and the called terminal by utilizing the call data . Since the call data includes the called number added with the routing delimiter, the service switching exchange receiving the call data can distinguish each call using the routing delimiter, and different call services are provided for each distinguished call can do.

According to another embodiment of the present invention, instead of directly inputting the card number, the calling number is inputted to the subscriber, and then the card number is searched based on the inputted calling number It is also possible. Specifically, in the parameter gathering step (S200), the service controlling exchange can collect the calling number of the subscriber set by the subscriber from the calling terminal and the called number corresponding to the called terminal to which the subscriber wishes to make a call connection. The parameter gathering step S200 may include a calling number request step S210 and a calling number receiving step S230 instead of the card number request step S210 and the card number receiving step S220. Here, the originating number request step (S210) may request the service switching exchange to send outgoing call number input announcement broadcast to the calling terminal by the service control switching center on a predetermined call, and the originating number collecting step (S220) When the exchange receives the calling number from the service switching center, it searches for the card number corresponding to the received calling number, checks the remaining amount of the prepaid card or the cumulative amount of money by using the card number, It is possible to determine whether or not it is usable. The rest of the configuration is the same as the above-described intelligent network interworking call service method, and a detailed description thereof will be omitted.

The present invention is not limited to the above-described embodiments and the accompanying drawings. It will be apparent to those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
