Abstract

A method and a system for handling real time charge for a concurrent call in an intelligent network are provided to handle charge for a service used by a prepaid subscriber even when the prepaid subscriber simultaneously uses two or more services among a voice call service, a packet data service and a message transmission service. If a first service provision request signal is received from a mobile terminal, first pre-subtraction costs, set to the first service in the communication balance of a prepaid subscriber, is allocated(S310.S330). By connecting a first call with the mobile terminal, the first service is provided(S340). If a second service provision request signal is received from the mobile terminal in a state when the call for the first service is connected, second pre-subtraction costs set to the second service in is allocated(S350,S352). By connecting a second call with the mobile terminal, the second service is provided(S354). According to a termination request for the first or second service, connection of the first or second call is released. After that, charge for the first or second service is accounted to be subtracted from the first or second pre-subtraction costs(S358,S380).

4 is a view for explaining a real-time charging processing method for a voice call and a data call simultaneously generated according to an embodiment of the present invention.

The present invention relates to a method and system for real time charging for a call simultaneously generated in an intelligent network. More specifically, when two or more calls among voice calls, data calls, and message calls occur simultaneously to a prepaid subscriber in an intelligent network system based on WCDMA, a real-time billing method for processing billing for each call respectively And thus a real time charging system.

Packet data that provides various information such as video, photo, music, news, traffic information in the form of text, voice, image, etc. using wireless network according to the rapid development of electronic and communication technology. In addition to services, various wireless communication services such as voice call service and message transmission service are provided.

In order to provide such a service, a mobile communication system has been developed through a first generation analog AMPS (Advanced Mobile Phone Systems) method and a second generation cellular / personal communication service (PCS) method. Recently, IMT-2000 (International Mobile Telecommunication-2000), a third generation high speed data communication, has been used. IMT-2000 was developed for personal mobility guarantee and high-speed data transmission to ensure mobility between countries by integrating systems of countries using different wireless access standards. It is asynchronous with Code Division Multi Access (CDMA) 2000, which is a synchronous method. It was developed separately from Wideband CDMA (WCDMA).

Since the WCDMA system uses a wider bandwidth than the CDMA method using a similar noise code unique to the subscriber's communication channel, the frequency selective fading is excellent, and the bandwidth is increased when the same data is transmitted, thereby increasing the processing gain. Therefore, the interference is reduced, which is suitable for transmitting a large amount of data. Accordingly, the Packet Data Service System (hereinafter referred to as 'GPRS') in WCDMA guarantees high speed transmission of packet data.

Meanwhile, general CDMA and WCDMA communication networks have provided uniform and simple services that are applied uniformly to all subscribers. Accordingly, call processing and billing principles have been mainly dealt with by the caller, and all call controls are fixedly identical by the exchange. Applied. Accordingly, the new service had to change the software of the exchange as a whole, thus providing the same service to all customers.

In order to solve this problem, to enable the application of new services developed without changing the software of the exchange, an IN (Intelligent Network) can be proposed to provide a variety of additional communication services directly to the CDMA network and WCDMA network Was applied. With the provision of such an intelligent network, service modification and supplementation can be processed quickly and accurately, and economical and efficient operation of the network becomes possible.

Voice call service, packet data service and message transmission service are provided to subscribers through WCDMA based intelligent network system. In providing such a service, a different billing system is operated for each service.

Voice call service, packet data service and message transmission service are typically provided one by one, but two or more services may be provided simultaneously. At this time, in the intelligent network system, the two or more services provided at the same time is assigned according to each billing system.

If the subscriber is a postpaid subscriber who later pays for the usage, no problem arises in the settlement of the cost for each of the services provided. However, in providing two or more services simultaneously to a prepaid subscriber who receives services only within the amount of the prepaid amount, the prepaid amount has been exhausted as a result of charging for the terminated service. If this is the case, there is a problem that the billing for other services that were used at the same time is not performed.

1A to 1D are signal flow diagrams illustrating a conventional charging method for a simultaneously generated call.

FIG. 1A is a signal flowchart illustrating a call processing step when receiving a data call while a voice call is in progress.

When a subscriber requests a voice call to an intelligent network system using a mobile terminal, a switch (MSC: Mobile Switching Center, hereinafter referred to as 'MSC') is a service control system (SCP) of an intelligent network system. After the voice call connection request signal is transmitted, a voice call is established through the received voice call connection signal, and a voice call is performed through the set voice call.

During a voice call for a voice call, if there is a data call connection request for providing a packet data service from a mobile terminal through a Serving GPRS Support Node (SGSN), Set up a session for the transfer of the call and proceed with the data call. When the data call is terminated, the created data session is released and data charging is received by receiving charging information on data usage from a real-time data charging system (DSCP: DSCP). At this time, if the deduction is normally made for data charging, the deduction result is transmitted to the DSCP.

When the voice call according to the voice call ends, the voice call connection is released and the charge charged for the voice call is deducted.

However, when the prepaid subscriber uses the voice call and the data call at the same time, if the call balance of the prepaid subscriber is exhausted due to the deduction of data billing, there is a problem that the voice call charge cannot be deducted when the voice call ends.

FIG. 1B is a signal flowchart for explaining a call processing step when receiving a voice call while a data call is in progress.

If a voice call connection request is input during a data session establishment and packet data service in accordance with a data call connection request from SGSN, a connection for a voice call is established and a voice call is performed. When the voice call ends, the voice call is disconnected and the charge charged for the voice call is deducted.

If the data call is terminated after the voice call charging is subtracted, the created data session is released and data charging is received by receiving charging information from the DSCP.

However, in the existing intelligent network system, when the balance of the prepaid fee is changed due to the voice call of the prepaid subscriber, SCP does not have a function to notify the DSCP of the balance change. Accordingly, when the prepaid charge balance is exhausted through the voice call, there is a problem that the data charge cannot be charged when the data call ends.

This failure to charge does not only occur between voice call service and packet data service, but also between message transfer service.

1C is a signal flowchart illustrating a call processing step when receiving a message call while a voice call is in progress. Here, various message transmission services such as a short message, a multimedia message, and a voice message may be provided through the message call.

During the voice call through the voice call connection established between the MSC and the SCP, if there is a message call connection request to use the short message service (SMS), multimedia message service (MMS), and voice message service (VMS), the message Create a message call session for sending and receiving a message. At this time, a session is established between the SCP and a message service center (SMSC: Short Message Service Center, MMSC: Multimedia Message Service Center, VMSC: Voice Message Service Center) that processes the message. When the message is transmitted and received through the generated message call session, the charging information for the transmitted and received message is transmitted to the intelligent network billing host (INBH). INBH forwards billing information to the SCP, including the amount deducted from the message, and SCP deducts the message fee in accordance with the billing information. At this time, if the deduction is normally made for the message charging, the deduction result is transmitted to the INBH.

After the message charge is deducted, when the voice call according to the voice call ends, the voice call connection is released and the charge charged for the voice call is deducted.

However, when the prepaid subscriber uses the voice call and the message call at the same time, if the call balance of the prepaid subscriber is exhausted due to the subtraction of the message charge, there is a problem in that the voice call charge cannot be deducted when the voice call ends.

FIG. 1D is a signal flowchart for explaining a call processing step when receiving a message call while a data call is in progress.

If a message call connection request for SMS, MMS, or VMS is input while establishing a data session and performing packet data service according to a data call connection request from SGSN, a session for sending and receiving a message is established and a message is sent and received. do. When the transmission and reception of the message is finished, the billing information from the INBH is used to subtract the message charging from the SCP.

If the data call ends after the message charging is subtracted, the created data session is released and the charging information is received from the DSCP to deduct the data charging.

Even in this case, SCP does not have the ability to notify DSCP of any balance change due to message charging, so if the prepaid subscriber's call balance is exhausted due to the deduction of message charging, the voice call will not be deducted at the end of the data call. Problems that can not occur.

As described above, in an intelligent network system, when a prepaid subscriber uses two or more services simultaneously among voice call service, packet data service, and message transmission service, when the prepaid payment amount is exhausted as a result of performing the charging according to the termination of one service, the prepaid subscriber uses the same service simultaneously. There is a problem that the charging is not performed properly for other services that are used at the same time.

In order to solve this problem, the present invention provides a prepaid rate subscriber located in an intelligent network system based on WCDMA, when each subscriber uses two or more services among voice call service, packet data service, and message transmission service simultaneously. The present invention provides a real-time billing method and a real-time billing system for allocating a deductible cost and processing billing for each service from the allocated prepaid deductible cost.

In order to achieve the above technical problem, the billing processing method according to the present invention is a billing processing method for two or more calls simultaneously generated at a mobile terminal of a prepaid subscriber, and (a) a request signal for providing a first service from the mobile terminal. When receiving the, the first prepaid deducting cost set in the first service from the call balance of the prepaid rate subscriber, and connecting the mobile terminal and the first call to provide a first service; (b) When the call request for the second service is received from the mobile terminal while the call for the first service is connected, the second pre-payment cost set in the second service is allocated, and the mobile terminal is connected to the second call. Providing a second service; And (c) disassociate the first or second call according to the request for termination of the first service or the second service, and settle the charge for the first service or the second service to settle the first prepayment cost or the second line. Subtracting from the deduction cost.

In addition, the billing processing system according to the present invention is a system for processing billing for two or more calls simultaneously generated in a mobile terminal of a prepaid bill subscriber, the subscriber information storage system for storing information about the prepaid bill subscriber and the mobile terminal; A service transmission system for generating a call connected to the mobile terminal, transmitting and receiving various signals with the mobile terminal using the generated call, and simultaneously providing two or more services to the mobile terminal; A service providing system for providing service data for providing two or more services; A billing settlement system that processes billing for two or more services provided to a mobile terminal; And upon receiving a request for providing at least two services from the mobile terminal at the same time through the service transmission system, confirms the prepaid rate subscriber's call balance and the deductible expenses respectively set for the two or more services through the subscriber information storage system, and charges And a control system for overall control of the billing processing step of deducting the currency balance by using each prepayment cost after processing each billing according to the provision of two or more services through the settlement system.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

In addition, when a part is said to "include" a certain component, this means that it may further include other components, except to exclude other components unless otherwise stated.

In addition, the term module described herein refers to a unit for processing a specific function or operation, which may be implemented in hardware or software, or a combination of hardware and software.

2 is a schematic diagram of a system for processing charging in real time for a call simultaneously generated according to an embodiment of the present invention.

The intelligent network 20 that handles billing for calls simultaneously generated in accordance with the present invention is a wireless access network 200, MSC 210, home location register 220, SGSN 230, SCP 240, intelligent peripherals 250, DSCP 260, INBH 270, message service center 280, and customer care device 290.

Radio access network (RAN) (hereinafter referred to as "RAN") 200 is a base station transmitter (RTS: Radio Transceiver Subsystem, hereinafter referred to as "RTS") that accommodates the radio access standard of the 3GPP standard to support WCDMA 202 and a radio network controller (RNC: RNC) 204. The RAN 200 receives a voice call service request signal, a packet data service transmission request signal, a message transmission / reception request signal, and uploading data from the mobile terminal 10, and transmits the received data to the MSC 210 or the SGSN 230. A data packet is received from 230 and transmitted to the mobile terminal 10.

The RTS 202 performs a radio access termination function with the mobile terminal 10 according to the 3GPP radio access standard, and transmits and receives voice, message, and packet data in a WCDMA manner and information with the mobile terminal 10 through a transmit / receive antenna. Send and receive. Here, the RTS 202 may also be used as the name 'Node B'.

The RNC 204 manages wired and wireless channels, protocol matching of the mobile terminal 10, and protocol matching of the RAN 200. It handles soft handoff processing, protocol matching with Core Network, GPRS access, fault management, system loading, and more.

The MSC 210 is a service switching point (SSP) for providing an intelligent network service, and performs an incoming and outgoing call processing of a subscriber, a location registration procedure and a handoff procedure, and an interworking function with another network. Also, it checks voice calls and message calls transmitted from subscribers and transmits them to SCP 240 and establishes a session between SCPs 240 to provide voice call service and message transmission service to mobile terminal 10. Perform.

The home location register (HLR) 220 stores the subscription type information of the intelligent network service subscriber, the intelligent network service trigger information, and the address information of the SCP 240, and moves. It performs functions such as registration recognition, registration deletion, and location checking of the terminal 10. In addition, the HLR 220 requests the location information of the mobile terminal 10 for data packet transmission from the SCP 240, and searches the database to store the SGSN (which is responsible for the area where the mobile terminal 10 is located). Check the address information of 230) and forward it to SCP (240). Here, the HLR 220 may be configured as a dual stack HLR supporting both the CDMA method and the WCDMA method.

The SGSN 230 supports a mobility management of the mobile terminal 10, a call processing procedure, and a session management and authentication function for handling transmission and reception of data packets for the GPRS service. In addition, it checks the data call transmitted from the mobile terminal 10 of the subscriber and transmits it to the SCP (240), and establishes a session for data call transmission between the SCP 240 to provide a packet data service to the mobile terminal (10) It serves to provide.

SCP 240 is a component that performs core functions in providing an intelligent network service, and is a data system in which program and subscriber data necessary for service control are concentrated.

SCP 240 may be configured as a dual stack SCP supporting both CDMA and WCDMA schemes, and may be a request signal of a voice call service or a message transmission service received from MSC 210 or SGSN 230. Analyze the request signal of the packet data service received from the system. The received packet data service request signal is transmitted to the intelligent peripheral device 250 or a separate content server that provides the packet data service, and the received message transmission service request signal provides various message services (SMS, MMS, VMS). Message service center (SMSC, MMSC, VMSC) 280 is delivered to.

In addition, SCP 240 stores billing information of subscribers who receive voice call service, packet data service, and message transmission service. In particular, when the subscriber is a prepaid fee subscriber, the balance information of the subscriber is stored, and the stored balance information is provided according to the balance inquiry request from the DSCP 260 or the INBH 270.

When a voice call, data call, or message call is generated according to a request for providing a service from a subscriber, the subscriber checks the usage time or usage of the service for the provided service, and the DSCP ( 260) or to the INBH 270.

If the billing information is received from the DSCP 260 or the INBH 270 as a settlement result for the service, the balance information is updated by deducting the balance of the prepaid rate subscriber, and the DSCP 260 or It serves to provide to the INBH (270).

In addition, according to the present invention, when the two-way service request signal of the voice call service, the packet data service, or the message transmission service is simultaneously received from the prepaid fee subscriber, the SCP 240 receives the prepaid and deductible cost previously set for the service. It checks and assigns each deduction fee to the requested service. The method of calculating the pre-tax deduction cost will be described in detail with reference to FIGS. 3 and 4.

Intelligent Peripheral (IP) 250 is difficult to implement through the MSC 210, or is expensive to impose specific functionality on all MSCs 210 located in the intelligent network 20. If this is consumed a lot, it is a device that can be configured to economically configure the MSC (210) by giving a corresponding function only to a specific MSC and by allowing a plurality of MSCs connected through the IP (210) to share the function. That is, the IP 250 may support voice services such as voice guidance, voice synthesis, voice recognition, and voice database information, and data services such as protocol conversion and connection to a data network.

The DSCP 260 is a part that performs real-time billing processing for the packet data service provided to the subscriber. The DSCP 260 calculates the amount to be subtracted using the subscriber's billing rate, the subscriber's service usage time, or the usage amount transmitted from the SCP 240, and the request for deducting the balance including the calculated amount as the billing information. 240).

In addition, the DSCP 260 is a data billing analysis function that performs an analysis on data charges imposed on the subscriber, the time the subscriber used the packet data service, the amount of data packets transmitted and received, the hourly / daily / monthly usage time or the packet amount. Or a system that performs data billing analysis.

The INBH 270 is a part for billing for the message transmission service provided to the subscriber in the form of SMS, MMS, VMS. The INBH 270 calculates the amount to be subtracted using message charge deduction information, such as the billing rate of the subscriber, the message usage of the subscriber, and the type of message used, delivered from SCP 240, and the balance deduction including the calculated amount. It performs the function of forwarding the request to the SCP 240 as billing information.

The message service center 280 is a system that provides a message transmission service to subscribers through SCP 240 and MSC 210. The message service center 280 provides various message transmission services such as SMS, MMS, and VMS to the mobile terminal 10. The message service center 280 stores the message received from the transmitting mobile terminal and transmits the message to the receiving mobile terminal through the SCP 240 and the MSC 210. At this time, if the message is not transmitted because the power of the receiving mobile terminal is turned off or is located in a shadowed area, the message is stored until a predetermined time set in advance or until the receiving mobile terminal becomes available for reception. When the message is transmitted to the receiving mobile terminal, the stored message is deleted.

Here, the message service center 280 may be one of an SMSC supporting SMS, an MMSC supporting MMS, and a VMSC supporting VMS, or may exist separately. In the following description, the message service center 280 will be described based on the MMSC, and it will be described on the assumption that the MMSC supports various message transmission services of SMS, MMS, and VMS.

The customer management device (WISE) 290 is a part for storing subscription information such as whether to subscribe / cancel service of an intelligent network service subscriber and a service registration state. To this end, the customer management device 290 is linked with the HLR 220 that stores the subscription type information of the subscriber. The mobile communication service provider inputs and manages subscriber terminal information, rate discount information, billing method, billing rate, etc. through the customer management device 290.

The real-time billing processing system configured as described above can be largely divided into a control system, a billing settlement system, a subscriber information storage system, a service providing system, and a service transmission system.

At this time, the control system is composed of SCP (240), the billing settlement system is SCP (240) to perform billing for voice calls, DSCP (260) to handle billing for data calls, billing for message calls It consists of an INBH 270 that processes. The subscriber information storage system consists of the HLR 220, the customer management device 290 and the SCP 240, the service providing system is composed of the IP 250 and the message service center 280, the service transmission system is RAN 200, the MSC 210, and the SGSN 230.

Through the real-time billing processing system configured as described above, billing processing for each service of a prepaid fee subscriber using two or more services among a voice call service, a packet data service, and a message transmission service can be performed.

To this end, the present invention uses a pre-deduction method that calculates a pre-deduction cost for voice calls, data calls, and message calls, and processes them.

Here, the pre-deduction method is to manage the balance for the prepaid subscriber in the form of a database, and when the simultaneous call (two or more calls among voice calls, data calls, and message calls) occurs, the amount that can be used for each call is used. It is set in advance so that the call can be made only for a predetermined amount. At this time, the available amount of money set in advance for each call is referred to as a deduction cost.

Such a pre-sensing scheme can be used in various cases, such as when a data call or message call is set up with a voice call set up, when a voice call or message call is set up with a data call set up, or when a voice call or data call is set up with a message call set up. In the following description, a description will be made based on a billing processing method when a packet call for a packet data service is set in a state where a voice call for a voice call service is set.

3 is a flowchart illustrating a billing processing method when a data call is received while a voice call is connected according to an embodiment of the present invention.

When the voice call service request signal is received from the mobile terminal 100 of the prepaid subscriber through the MSC 210 (S310), the SCP 240 confirms the subscriber information through the HLR 220 and the customer care device 290. . If the subscriber information is confirmed, the subscriber's call balance is stored. At this time, the subscriber checks the pre-deduction cost set for each call (S320).

SCP 240, which has confirmed the cost set by the subscriber in advance for the voice call, allocates the voice call deduction cost from the subscriber's call balance (S330), and within the limit of the allocated voice call deduction cost, the voice call. To perform (S340).

While the voice call is set up and the voice call is being performed, when the packet data service request signal is input from the mobile terminal 100 through the MSC 210 (S350), the data call deduction cost set for the data call is checked. . Then, after allocating the data call deduction cost from the call balance from which the voice call deduction cost is subtracted (S352), a data call is set up and a packet data service is provided. At this time, the packet data service is executed within the limit of the allocated data call deducting cost. SCP 240 provides data charge deduction information to DSCP 270 while packet data service is provided.

The packet data service is terminated after the transmission of the data packet is completed, or is provided up to a limit of a preset data call deducting cost (S354).

When the transmission of the data packet is completed and the packet data service is terminated (S356), the set data call is released and charging information for the packet data service used from the DSCP 270 is received. Then, the amount according to the received billing information is subtracted from the allocated data call deduction cost (S358).

At this time, the remaining amount after deducting the amount used for the packet data service from the data call deduction cost is returned to the call balance of the prepaid subscriber (S360).

However, when the transmission of the data packet is completed in step S356 and the data call service is not terminated, and if the packet data service corresponding to the preset pre-decrease cost is provided, the packet is first transmitted at the allocated data call deduction cost. The remaining amount is changed to 0 won by subtracting the amount used for the data service (S362).

In operation S364, it is checked whether a call balance of a prepaid subscriber exists. At this time, if there is a call balance of the prepaid subscriber, after the step S354 of further allocating a data call deduction cost from the call balance and continuously providing a packet data service using the allocated data call deduction cost. do. Such a packet data service is terminated after the transmission of the data packet is completed, or is provided up to the limit of the additional pre-decrease cost (S366).

However, if it is confirmed in step S364 that the call balance of the prepaid subscriber does not exist, the set data call is released to terminate the packet data service (S368).

When the packet data service is terminated through the step S360 or S368 or when there is no input of the packet data service request signal in the step S350, the SCP 240 checks whether the voice call service termination request has been received (S370).

When a voice call service termination request is received, SCP 240 terminates the voice call to disconnect and settles the cost used for the voice call. Then, the voice call charge used for the voice call is subtracted from the allocated voice call deduction cost (S380).

If a balance exists as a result of subtracting the voice call charge used for the voice call from the voice call deduction cost, the refund is made to the call balance of the prepaid subscriber (S390).

However, in step S370, when the voice call service termination request is not received, SCP 240 checks whether or not the voice call has been provided up to a preset voice call deduction cost (S372).

If it is determined that the voice call has not been provided to the limit of the preset voice call deduction cost, the voice call is continuously performed using the allocated voice call deduction cost. However, if it is confirmed that the voice call has been provided to the limit of the preset voice call deduction cost, it is checked whether the subscriber's call balance exists (S374).

At this time, if the subscriber's call balance is present, a step after S340 in which the voice call deducting cost is additionally allocated from the call balance to continue the voice call is performed (S376). However, if it is confirmed that the subscriber's call balance does not exist, SCP 240 terminates the voice call to terminate the voice call service.

As described above, in the billing processing method when a data call is received during a voice call, one data call may be received during the voice call, but a plurality of data calls may be received.

4 is a diagram illustrating a real-time charging processing method for a voice call and a plurality of data calls simultaneously generated according to an embodiment of the present invention.

4 is a billing processing method when a call balance of a prepaid subscriber is 1000 won, a voice call deduction cost is set to 500 won, and a data call deduction cost is set to 200 won.

When a voice call is initiated in response to a voice call service request, a predetermined 500 won is allocated as a voice call deduction cost. At this time, the first data call, the second data call, the third data call and the fourth data call are respectively started while the voice call is in progress.

When performing the prepayment method for the data call, the remaining currency balance of 500 won is allocated as the data call deduction cost for each data call. That is, 200 won for the first data call, 200 won for the second data call, and 100 won for the third data call are allocated to the respective data call deduction cost. At this time, since the call balance is allotted to the first to third data calls, the fourth data call cannot be connected and is rejected.

Since the data call deduction cost for the third data call is 100 won, the third data call ends after receiving 100 won worth of data. Accordingly, the actual call balance of the prepaid subscriber is changed to 900 won.

In connecting the second data call, if the reception of the second data is completed and the connection of the second data call is released before all of the 200 won, which is the data call deduction cost allocated to receiving the second data, is completed, the data call Only the amount used to receive the second data is subtracted from the prepayment cost. If 150 won is consumed to receive the second data, 150 won is deducted from 200 won, which is a data call deduction cost, and the remaining amount of 50 won is returned to the prepaid subscriber's call balance. Accordingly, the subscriber's call balance is changed to 750 won.

In the connection of the first data call, when 200 won worth of data, which is the data call deduction cost allocated to the first data call, is received, the 200 won of the data call deduction cost is subtracted from the subscriber's call balance. Accordingly, the subscriber's call balance is changed to 550 won. In order to continuously receive the first data, an additional allocation of the data call deduction cost is requested, and 50 won except for the 500 won allocated as the voice call deduction cost from the call balance of 550 won does not receive the first data. It is additionally allocated as a data call deduction cost. Accordingly, after additionally receiving the first data of 50 won worth, the first data call is disconnected and the data call service is terminated.

At this time, the voice call service is terminated when all the 500 won, the voice call deduction cost is exhausted. If the voice call service is terminated before the voice call deduction cost of 500 won is exhausted, the remaining balance is refunded to the call balance of the prepaid subscriber.

In the above, only the case where the data call is received while the voice call is set is described. However, when the message call is received while the voice call is being set, when the voice call or the message call is received while the data call is set, the message call is set. It is also possible to apply when a voice call or a data call is received during the operation.

The embodiments of the present invention described above are not implemented only through the apparatus and the method, but may be implemented through a program for realizing a function corresponding to the configuration of the embodiment of the present invention or a recording medium on which the program is recorded. Implementation may be easily implemented by those skilled in the art from the description of the above-described embodiments.

Although the embodiments of the present invention have been described in detail above, the scope of the present invention is not limited thereto, and various modifications and improvements of those skilled in the art using the basic concepts of the present invention defined in the following claims are also provided. It belongs to the scope of rights.

As described above, according to the present invention, in the intelligent network system, even if a prepaid subscriber uses two or more services simultaneously among a voice call service, a packet data service, and a message transmission service, the prepaid subscriber clearly performs the charging for the used service. You can expect the effect to work.
