In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic diagram of a network configuration of a system for providing a discount service for an IN charging prepaid subscriber according to an embodiment of the present invention. Referring to FIG.

1, the system according to the present embodiment includes mobile terminals 110 and 130, a communication network 150, a service switching point (SSP) 170, and a service control point (SCP) do. The mobile terminal 110 will be described as the calling terminal 110 that originates the call and the mobile terminal 130 will be described as the called terminal 130 that receives the incoming call.

The mobile terminals 110 and 130 are terminals provided with a function of transmitting / receiving a voice / video call function, a text message (including a short message and an MMS message), and can be applied to any terminal providing a voice or / do.

The communication network 150 is a communication network for providing mobile communication services. The communication network 150 includes a base station for managing radio resources, a base station controller for controlling the base station, an exchange for performing an incoming call and outgoing call processing, And a home location register (HLR) for storing and managing the location information and the subscriber profile of the subscriber.

When the communication subscriber is subscribed to the service according to the present invention, the home location register (HLR) is configured such that when the terminal of the communication subscriber tries to register the location so that the call processing of the communication subscriber is guided to the intelligent network system and processed It provides trigger information about intelligent network system with exchange. Accordingly, when the communication subscriber sends a call, the outgoing call is directed to the intelligent network system and processed in the intelligent network system.

The SSP 170 is an intelligent network node that performs an intelligent network service switching function. When the prepaid subscriber makes a call, the SSP 170 downloads information related to the call processing of the prepaid subscriber from the SCP 190, And provides a call service between the prepaid subscriber and the called subscriber and reports a call processing result including the subscriber's carrier information to the SCP 190 during and / or after the call. The SSP 170 may be integrated into the exchange, or may be implemented in the form of a separate device from the exchange.

For example, in the 2G communication standard, the SSP 170 transmits a analyzedinfo message to the SCP 190 when an outgoing call of the prepaid subscriber is input, and prepares the prepaid balance of the prepaid subscriber, Download subscription information, and make a call connection to the called subscriber. At this time, the SSP 170 confirms the carrier information to which the called subscriber is subscribed based on the exchange information included in the call setup response received from the receiver side exchange. After the SSP 170 provides a call service between the calling subscriber and the called subscriber within the prepaid subscription range, the SSP 170 transmits a CRR (Call Result Report) message including the confirmed subscriber's carrier information and the call termination result To the SCP (170).

As another example, in the 3G communication standard, the SSP 170 provides a call service between the prepaid subscriber and the called subscriber by receiving an outgoing call to the called subscriber when an outgoing call of the prepaid subscriber is inputted. At this time, the SSP 170 transmits a service request message (Initial DP) to the SCP 190 as an initialization process before receiving the call, and receives a call information request message (CIRQ: CallInformationRequest) from the SCP 190 do. The call related information includes the call attempt time, the call end time, the call set time, the call termination cause, and the SSP 170 reports the call related information to the SCP 190 when the call termination is completed.

In addition, the SSP 170 downloads and stores a list of events to be reported in association with outgoing call processing from the SCP 190 in the initialization process, and when an outgoing call is processed, whenever the event corresponding to the event list occurs SCP (190). The event list is shown in [Table 1]. At this time, when the called subscriber answers the call and reports the event to the SCP (190), the SSP (170) checks the subscriber's subscription information and reports together.

The SSP 170 stores a mapping table in which the exchange information and the carrier information are mapped to identify the carrier information of the called subscriber as described above, and uses the destination exchange information included in the call response received from the destination exchange And confirms the carrier information to which the called party is subscribed in the mapping table.

The service control point (SCP) 190 is an intelligent network node that performs intelligent network service logic in cooperation with the SSP 170. The SSP 170 controls the prepaid subscriber's call in response to a service request of the SSP 170 The prepaid subscriber's balance, the total available time information, and the like, and subtracts the call charge from the balance of the prepaid subscriber in real time according to the call processing information of the prepaid subscriber reported from the SSP 170.

In the present invention, the SCP 190 stores and manages the profile of the prepaid subscriber. In addition to the existing prepaid service subscription information field, the subscription information field of the prepaid subscriber is additionally added to the profile, The related service code is recorded in the call discount service subscription information field. In the call discount service, a plurality of commodities exist, and a service code corresponding to a product of the call discount service to which the prepaid subscriber is subscribed is recorded in the call discount service subscription information field.

In addition, the SCP 190 stores and manages a discount rate table for each call discount service code. FIG. 4 shows an example of a discount rate table according to a discount rate table for each discount rate code. As shown in FIG. 4, discount rate tables are provided for each discount rate code 410 (e.g., ID = 1) Discounts the prepaid subscriber's call charge by referring to the discount rate table corresponding to the call discount service code to which the prepaid subscriber belongs. 4, the discount rate table includes a field (OMTC: OperatorMyTypeCode) 430 for identifying a communication carrier, and fields 450 and 470 in which a discount rate is recorded for each communication carrier . The SCP 190 retrieves the discount rate from the discount rate table using the information OMTC of the communication carrier to which the called subscriber is subscribed, reported from the SSP 170, and deducts the balance according to the retrieved discount rate.

Hereinafter, with reference to FIG. 2 to FIG. 3, a method of discounting a call charge of an intelligent network prepaid service subscriber in the system of FIG. 1 will be described in detail.

FIG. 2 is a signal flow diagram illustrating a method of discounting a call charge of an INC prepaid subscriber according to an embodiment of the present invention, and is an example of a call processing procedure according to the 2G communication standard.

As shown in FIG. 2, the intelligent network prepaid subscriber who subscribes to the discount service according to the present invention transmits a call call from his / her calling terminal 110. When a call is originated at the calling terminal 110, the calling signal is inputted to the SSP 170 (S201).

For example, when a call is originated at the calling terminal 110, an outgoing call is transmitted to a calling side exchange through a radio access network, and the calling side exchange checks the subscriber profile of the caller stored in the visiting location register, . At this time, as the trigger information of the caller, the trigger information for the home location register, which accommodates the caller's information, is set, and therefore, the caller-side switching center has a home location register And receives routing information for the SSP 170 connection from the home location register. The originating exchange exchanges calls to the SSP 170 according to the received routing information.

In response to the incoming call, the SSP 170 transmits the analyzedinfo message to the SCP 190 (S203). The analyzedinfo message includes the identification information of the calling terminal 110 and the identification information of the called terminal 130. [

The SCP 190 receiving the analyzedinfo message searches the prepaid service subscription information of the caller using the identification information of the calling terminal 110 included in the analyzedinfo message, and transmits a response message including the retrieved prepaid service subscription information to the SSP (Step S205). The prepaid service subscription information includes prepaid balance, total available time information, and the like.

Upon receiving the response message, the SSP 170 sets a call to the called terminal 130 using the identification information of the called terminal 130 (S207). Specifically, the SSP 170 queries the home location register for receiving destination location information and sets up a call with the destination terminal 130 based on the received destination location information. In this process, the SSP 170 confirms the carrier information to which the called party is subscribed (S209). The SSP 170 confirms the communication carrier information of the called party based on the exchange information included in the call response message received from the destination exchange. The SSP 170 can confirm the information of the called party exchange and check the information of the carrier to which the called party is subscribed since the call is received through the exchange of the communication carrier to which the called party is subscribed.

The call between the calling terminal 110 and the called terminal 130 is established and the call is initiated and the SSP 170 transmits the call between the calling terminal 110 and the called terminal 130 in the range of the prepaid balance of the caller To provide a call service. The SSP 170 can send a warning message to the calling terminal 110 when the prepaid balance falls below a predetermined threshold value and can terminate the call if the balance is exhausted.

Thereafter, when the call between the calling terminal 110 and the called terminal 130 is terminated (S211), the SSP 170 transmits a Call Result Report (CRR) message including information on the terminated call to the SCP (Step S213). The information included in the call result report message includes identification information of the caller and the called party, the call start time (CallStartTime), the call end time (CallEndTime), and the business information (OMTC) to which the called party is subscribed.

Upon receiving the call result report message, the SCP 190 subtracts the prepaid balance of the caller based on the information included in the call result report message, and first searches the profile of the caller for the discount code of the call service to which the caller subscribes S215). Subsequently, the SCP 190 searches the discount rate table corresponding to the searched discount service code (S217).

Then, the SCP 190 retrieves the discount rate corresponding to the carrier information to which the called party is subscribed in the searched discount rate table (S219), calculates the final call charge according to the searched discount rate, (S221). Specifically, the SCP 190 first calculates a call rate based on the talk time included in the call result report message, and then discounts the calculated call rate according to the searched discount rate. And subtracts the discounted call rate from the prepaid balance of the caller.

As described above, the subscriber of the intelligent network prepaid service does not receive a collective discount for all calls, but receives discounts at different rates depending on the communication carrier to which the other party is subscribed. According to the present invention, the intelligent network prepaid service subscribers can also subscribe to various discounted commodity discount products when the communication subscribers join the intelligent network prepaid service. However, according to the present invention, The telecommunication service can be used for the fee and the telecommunication company can attract more subscribers.

FIG. 3 is a signal flow diagram illustrating a method for discounting a call charge of an INC prepaid subscriber according to another embodiment of the present invention, and is an example of a call processing procedure according to the 3G communication standard.

Referring to FIG. 3, the intelligent network prepaid subscriber who subscribes to the discount service according to the present invention transmits a call call at his / her calling terminal 110. When a call is originated at the calling terminal 110, the calling signal is input to the SSP 170 (S301). Generally, in the 3G communication standard, the function of the SSP 170 is integrated into the exchange. Thus, upon receiving an outgoing call at the originating exchange, the originating exchange connects to the caller's home location register according to the trigger information of the originator registered in the visited location register and receives routing information for connection to the SCP 190. The SSP (170) of the originating side switch connects to the SCP (190) according to the received routing information.

The SSP 170 transmits an Initial DP message, which is a service request message, to the SCP 190 in the call connection to the SCP 190 (S303). The service request message includes identification information of the calling terminal 110 and call type information of the outgoing call.

The SCP 190 performs user authentication, balance check, validity period check, status check (pause, etc.) based on the identification information and call type information of the calling terminal 110 included in the service request message, If not, perform initialization process for prepaid service.

Specifically, the SCP 190 transmits a call information request message (CIRQ: CallInformationRequest) to the SSP 170 for reporting the call related information from the SSP 170. The call related information includes a call attempt time, a call end time, a call set time, and a call termination cause. Also, the SCP 190 transmits a call management message (AC: ApplyCharging) to the SSP 170 for managing the call duration (S305). The call management message includes information such as a talkable time, a response period for a call management message, a connection termination at the lapse of a talkable time, and a tone generation time of 30 seconds. Of these, whether or not to terminate the connection when the talkable time elapses and whether to generate the tone 30 seconds before are included when the call management message is last sent.

In addition, the SCP 190 sends an event list (RRB: RequestReportBCSMEvent) to be reported in association with call processing to the SSP 170 (S307). The event list is the same as the example of Table 1 above. Then, the SCP 190 transmits a connect message for the continuous progress of the outgoing call to the SSP 170. In the initialization process as described above, steps S305 to S307 may be performed simultaneously or in a different order without being performed in the order shown in the drawings.

When the initialization process is completed, the SSP 170 sets a call between the calling terminal 110 and the called terminal 130 by performing an incoming call processing of an outgoing call of the calling terminal 110 according to a normal procedure (S309). In this process, when a call response (Answer) for call set-up is received from the receiver-side switching center, the SSP 170 uses the identification information of the called-party exchange included in the call response, Check. The SSP 170 can confirm the carrier information to which the called party is subscribed by using the information of the called party exchange.

In response to receiving the call response, the SSP 170 refers to the registered event list in the initialization process and reports a call response event (ERB: EventReportBCSM) according to the reception of the call response to the SCP 190 (S311) . At this time, the SSP 170 inserts the communication service provider information (OMTC) of the called party identified in step S309 in the call response event and transmits the same.

Upon receiving the call response event, the SCP 190 prepares for deduction of the prepaid balance of the caller, and first searches the profile of the caller for the discount code for the discounted call service (S313). Then, the SCP 190 searches the discount rate table corresponding to the searched discount service code (S315). Then, the SCP 190 retrieves the discount rate corresponding to the information of the communication carrier to which the called party is subscribed in the retrieved discount rate table (S317).

Meanwhile, the SSP 170 transmits the call response (T) after reporting a call response event based on the response period T recorded in the call management message AC received from the SCP 190 in the initialization process (step S305) (ACR: ApplyChargingReport) to the SCP 190 (S319).

The SCP 190 calculates the talk time of the caller upon receiving the call management response message (ACR). That is, since the call management response message is received for the first time after the call setup, the call time is calculated by the transmission period T of the call management response message. Then, the SCP 190 calculates a call charge based on the calculated talk time, applies a discount according to the discount rate searched for the call charge, calculates a final call charge, and subtracts the call charge from the prepaid amount of the caller (S321 ).

Then, the SCP 190 transmits a call management message (AC) to the SSP 170 again (S323). Then, the SCP 190 receives the call management response message (ACR) again from the SSP 170 according to the cycle recorded in the call management message AC, calculates the call charge according to the above procedure, Repeat the process of deducting the charge from the balance.

The SSP 170 reports the call termination event to the SCP 190 in step S327 and the SSP 170 transmits the call management response message ACR to the SCP 190. In step S325, (Step S329). At this time, the call management response message sent after the call termination is not sent according to the transmission period but is transmitted immediately after the call termination to notify the call termination. SCP 190 receives the call management response message (ACR) to confirm call termination and deducts the final charge from the user's prepaid balance.

In response to the call related information request message (CIRQ) transmitted to the SSP 170 in the initialization process, the SCP 190 receives from the SSP 170 a call attempt time, a call end time, a call setup time, Related information response message (CIRPT) including the CIRPT and the like (S331). The SCP 190 transmits Furnish Charging Information (FCI) including the information recorded in the call related information response message and the detailed information (e.g., calling number, destination number, service type, billing amount) ). The SSP 170 generates billing data based on the information included in the FCI, and transmits the billing data to the billing server. The billing server creates billing statements and provides the billing information to the users.

As described above with reference to FIG. 3, the intelligent network prepaid subscriber does not receive a collective discount on all calls but receives the discount in real time at different rates according to the communication provider to which the other party is subscribed. According to the present invention, the intelligent network prepaid service subscribers can also subscribe to various discounted commodity discount products when the communication subscribers join the intelligent network prepaid service. However, according to the present invention, The telecommunication service can be used for the fee and the telecommunication company can attract more subscribers.
