Abstract

PURPOSE: A collect-call service method is provided to resolve the call charge load of a recipient according to the use of a collect-call service. CONSTITUTION: If a collect-call request message is received from an origination-side terminal after a service subscription about each terminal subscriber is completed(S5), a service server confirms whether a subscriber enters the service using a communication number of the origination-side terminal and judges the validity of the origination-side terminal as to the collect-call service(S6). If the origination side previously enters the service and the service as to the collect-call service is valid, the service server transmits an affirmative acknowledge to the origination-side terminal(S7). The origination-side terminal provides a communication number of a termination-side terminal to the service server(S8). The service server pages the receipt-side communication number received from the origination-side terminal, and inquires whether the collect-call is received to the termination-side terminal(S9). If an acknowledge for admitting the receipt of the collect call from the termination-side terminal(S10), the service server connects a channel between the origination-side terminal and the termination-side terminal for performing a telephone conversation between two terminals(S11).

Description

Collect-call service method

The present invention relates to a call service through a communication network, and more particularly, to a collect call service method suitable for reducing a call cost burden of a receiver by using a collect call service.

Currently, wired and wireless network service providers provide collect call services.

A collect call service is a service that charges a call charge to a receiver, unlike a charge caller generally.

The procedure for using the current collect call service is as follows.

First, the caller issues a call to the designated number for the collect call service. The designated number is predetermined by the network service provider.

In a network service center, a caller is provided with a caller's number and a caller's identity to be called in a toll free manner.

The service center issues a call to the provided recipient number and, if there is a response from the receiver, informs the caller of his / her identity through the call with the recipient and also inquires whether to accept the toll free call.

The service center connects the caller with the caller when the caller accepts the call.

After the connected call is over, the service center updates the call charge for the call in the receiver's database.

Since the collect call service described above imposes a call charge on the receiver, it acted as a burden on the receiver.

An object of the present invention has been made in view of the above point, in particular, to provide a collect call service method for relieving the call charge burden of the receiver by using the collect call service.

A first aspect of the collect call service method according to the present invention for achieving the above object comprises: a first step of connecting a call between a calling terminal and a receiving terminal when a collect call call is requested; A second step of transmitting one or more advertisements to the receiving terminal as the call between the two terminals is terminated; Calculating a compensation amount according to a degree of transmission of the advertisement; And a fourth step of charging the subscriber of the receiving terminal by subtracting the calculated compensation amount from the service charge according to the call.

In the first step, as the collect call request message including the communication number of the calling terminal is received from the calling terminal, the caller determines whether the calling party subscribes to the service using the calling number of the calling terminal. Preferably, the validity of the calling terminal for the collect call service is determined.

The second step transmits, to the receiving terminal, one or more advertisements with a command sending portion inserted therein for automatically transmitting a rejection of transmissions for subsequent subsequent transmission sequences, and transmits an advertisement from the receiving terminal. As the rejection command is received, it is preferable to terminate the advertisement transmission.

A second aspect of the collect call service method according to the present invention for achieving the above object is, as the collect call between the calling terminal and the receiving terminal is terminated, the call charge for the collect call call to the receiving terminal Sending it to; Inquiring whether the receiving terminal receives the advertisement; Informing a degree of advertisement to be received for the collect call call to be free; As the advertisement corresponding to the call rate of the collect call call is transmitted to the receiving terminal, the advertisement transmission is automatically stopped.

A third aspect of the collect call service method according to the present invention for achieving the above object is, when a collect call call is requested from an originating terminal, at the same time querying the receiving terminal whether or not to receive the collect call; Sending one or more advertisements to the terminal; Stopping the advertisement transmission to the originating terminal and accepting a call between the calling terminal and the receiving terminal when the collect call reception is accepted from the receiving terminal; In the service charge for the connected call, a compensation amount corresponding to the transmission of the advertisement to the calling terminal is subtracted, and charging the subscriber of the receiving terminal.

A fourth aspect of the collect call service method according to the present invention for achieving the above object comprises: a first step of continuously transmitting an advertisement to the calling terminal as the collect call request message is received from the calling terminal; A second step of delivering a free call time corresponding to the degree of continuous transmission of the advertisement to the calling terminal; A third step of informing the calling terminal of the total free talk time as the advertisement transmission to the calling terminal is terminated; Connecting a call between the calling terminal and the called terminal; And a fifth step of charging a service fee corresponding to the level of the connected call to the subscriber of the receiving terminal.

In the fourth step, when the call between the caller terminal and the receiver terminal is connected, the talk time is exceeded to the caller terminal to the receiver terminal as the talk time exceeds the total free call time. It is desirable to inform.

After the fourth step, as the call is terminated at the time when the total free call time is exceeded, it is preferable to calculate the toll charge for the terminated call.

The service server 10, which is a key element of the present invention, performs the operations listed below.

First, service registration for network subscribers. Through registration of the service, the basic personal information of each subscriber and the subscriber's communication number (mobile telephone number, landline telephone number and Internet identification account) are registered.

Second, with reference to the personal information about each subscriber registered in the service, among the various advertisements requested, it targets the advertisement suitable for the identity of each subscriber.

Third, when a collect call service request is generated from a specific subscriber, it is checked whether the service is subscribed to the subscriber who requested the service, and whether the subscriber uses the collect call service is determined.

Fourthly, when a call proceeds through a collect call service, an operation for selecting an advertisement field and a service mode to be provided to a subscriber is performed. To this end, the service server provides a driving environment that allows the subscriber to select a desired advertising field, and provides a driving environment that allows one service mode to be selected from a collect call service and a general communication service. When the subscriber selects the advertisement field and the service mode through the provided driving environment, the subscriber provides a collect call service according to the selected contents, and transmits the advertisement to the subscriber terminal (calling terminal or receiving terminal).

Fifth, the compensation information is calculated according to the advertisement transmission, and the compensation information is transmitted to the billing center so that the calculated compensation can be applied to the call charges according to the collect call currency. Then, the compensation details according to the advertisement transmission are transmitted to the corresponding calling terminal or receiving terminal.

In addition, the description of other operations of the service server 10 will be described in more detail through the service procedure described below.

Referring to FIG. 2, the service server includes an option selection module 11, a basic service module 12, an advertisement processing module 13, and a reward calculation module 14 for the operations already described above. do.

The option selection module 11 is operated so that subscribers (calling party or receiving party) can select the advertising field and service mode to be provided.

The basic service module 12 performs service registration for various terminal users, and through the service registration, basic personal information of each terminal user, a communication number used by the user (mobile telephone number, wired telephone number, and the Internet). ID account is registered. The caller terminal sending the collect call service request is checked for subscription, and the validity of the use of the collect call service is determined. The most basic terminal is connected to the call path, and before and after the call, the advertisement is sent to the calling party or the receiving party. In addition, the compensation details according to the advertisement transmission is transmitted to the calling terminal or the receiving terminal.

The advertisement processing module 13 registers and processes various requested advertisements, and targets an advertisement suitable for each subscriber's image by referring to the personal information about each subscriber registered by the service subscription. The advertisements are transmitted to the subscriber terminal, and the transmission time or the degree of transmission of the advertisements are checked.

The reward calculation module 14 calculates a reward to be paid to the subscriber according to the transmission time or the degree of transmission of the advertisement checked through the advertisement processing module 13. Then, the calculated compensation information is transmitted to the charging center.

The following describes a collect call service procedure using the system configuration and operation described above.

3 is a view illustrating a service subscription and a collect call call procedure in a collect call service of post-call advertisement transmission according to a first embodiment of the present invention, and FIG. 4 is a post-call advertisement transmission according to a first embodiment of the present invention. A diagram illustrating the procedure.

3 to 4 is a case of reducing the call charges of the receiving subscriber according to the use of the collect call service by providing a predetermined amount of advertisement to the receiving terminal after the collect call.

First, referring to FIG. 3, a service subscription and collect call call procedure is first performed.

The service subscription request of the present invention is received from the calling terminal (or receiving terminal) (S1).

Accordingly, the service server inquires the registration information for the service subscription to the terminal requested to subscribe, and also asks the subscriber (the sending side or the receiving side) the option information of the service to be provided (S2).

Accordingly, the service server receives each subscriber's personal information and communication number from the calling terminal (or receiving terminal), and receives the advertisement field and service mode (service type) selected by the subscriber as option information (S3).

The service server registers the received personal information and communication number (mobile phone number, landline phone number and internet identification account) used by each subscriber, and subscribes to the service option (advertisement field and service type to be provided) selected by each subscriber. It is set separately (S4).

In FIG. 3, the service subscription process (S1 to S4) is expressed as being simultaneously performed for the calling party and the receiving party, but in practice, the service subscription of the calling party and the service subscription of the receiving party are considered separately.

If a collect call request message (message including a communication number of the calling terminal) is received from the calling terminal after the service subscription for each terminal subscriber is completed (S5), the service server requests the calling call. Using the communication number of the subscriber to confirm whether the subscriber subscribes to the service and at the same time determine the validity of the calling terminal for the collect call service (S6).

If the calling party is subscribed in advance and it is determined that the service is valid for the collect call service, the service server sends a positive response Affirmative_ACK to the calling terminal (S7).

Accordingly, the calling terminal provides the service server with the communication number of the called terminal to be called (S8).

The service server calls the receiving communication number provided from the calling terminal and inquires whether the called terminal receives the collect call (S9). When the service server inquires whether the collect call is received, the service server provides the receiving terminal with personal information stored in the database in association with the communication number of the calling terminal that requested the collect call. Helps to determine whether to receive.

If an acknowledgment (ACK) of accepting the collect call reception is received from the receiving terminal (S10), the service server connects a call path between the calling terminal and the receiving terminal to allow a call to be made between the two terminals (S11). .

4, after the call is terminated, the call path between the calling terminal and the receiving terminal is released (S12). The actual service server releases only the call route to the calling terminal and saves the call route to the receiving terminal. The service server calculates a call fee for the terminated call (S13). At the same time, the service server sends the calculated call rate to the receiving terminal, and transmits the calculated call rate to the charging center to update the receiving terminal subscriber database for charging.

In addition, the service server inquires whether the receiving terminal receives the advertisement (S14). If a response (ACK) for accepting the advertisement is received from the receiving terminal (S15), the service server transmits a plurality of advertisements to the receiving terminal (S16). At this time, each advertisement transmitted is inserted with a command sending portion for automatically sending a rejection of transmission of advertisements in subsequent transmission sequences.

Thereafter, if an advertisement transmission rejection command is received from the receiving terminal, the service server terminates the advertisement transmission (S17). And calculates a compensation corresponding to the transmission of the advertisement up to that time (S18). At the same time, the service server sends the calculated compensation to the receiving terminal, and also delivers the calculated compensation to the charging center to update the receiving terminal subscriber database for charging. To this end, the billing center is equipped with a database for each terminal subscriber. The database for each subscriber loads call charges for collect call calls and call charges for general voice calls and data transmission, and for each collect call call. It is composed of the part that loads the compensation amount corresponding to the advertisement receipt in connection with the call charge.

Compensation calculation according to the advertisement transmission is calculated in proportion to the degree of the transmitted advertisement (the number of advertisements transmitted or the length or time of advertisement transmission), or is calculated in proportion to the reproduction time of the transmitted advertisement.

The service server notifies the receiving terminal of a value obtained by subtracting the reward calculated thereafter from the calculated call rate (S19).

Separately, the service server sends a call charge to the receiving terminal after the call is terminated and also inquires whether to receive an advertisement, and tells how long or how long the advertisement should be viewed before the collect call is free. Therefore, the receiving terminal subscriber can know how much to receive the advertisement. In addition, the service server automatically stops the advertisement transmission when an advertisement corresponding to the call rate of the collect call call is transmitted to the receiving terminal.

5 is a diagram illustrating a call procedure after transmitting an advertisement according to a second embodiment of the present invention.

5 is a procedure for reducing a call charge of a receiving subscriber according to the use of a collect call service by providing an advertisement to a calling terminal before a collect call call.

Referring to FIG. 5, service subscription procedures S1 to S4 for each terminal of the calling party and the receiving party are performed in the same manner as in FIG. 3.

When the collect call request message (message including the communication number of the calling terminal) is received from the calling terminal that has completed the service subscription (S20), the service server uses the communication number of the calling terminal that requested the collect call to service the subscriber. At the same time, it is checked whether or not the subscription is made and the validity of the calling terminal for the collect call service is determined (S21).

If the calling party is subscribed in advance and it is determined that the service is valid for the collect call service, the service server sends an affirmative_ACK to the calling terminal (S22).

Accordingly, the calling terminal provides the communication server of the called terminal to be called to the service server (S23).

The service server calls the receiving communication number provided from the calling terminal and inquires whether the called terminal receives the collect call (S24).

The service server inquires whether or not the collect call is received by the receiving terminal and simultaneously transmits a plurality of advertisements to the calling terminal (S25).

Thereafter, if a response (ACK) is received from the receiving terminal to accept the collect call (S26), the service server stops transmitting the advertisement to the calling terminal (S27), and establishes a call path between the calling terminal and the receiving terminal. The connection is made between the two terminals (S28).

After the call is terminated, the call path between the calling terminal and the receiving terminal is released (S29). The service server calculates a call fee for the terminated call (S30). Here, the call charge is an amount obtained by subtracting a compensation amount due to the advertisement transmission to the calling terminal from the service use charge in proportion to the actual call time.

The service server notifies the receiving terminal of the calculated call rate (actual call rate-compensation) (S31). At the same time, the service server transmits the calculated call rate to the charging center to update the receiving terminal subscriber database for charging (S32).

6 is a flowchart illustrating a call procedure after transmitting an advertisement according to a third embodiment of the present invention.

6 is also a procedure for reducing the call charge of the receiving subscriber according to the use of the collect call service by providing an advertisement to the calling terminal before the collect call call.

Referring to FIG. 6, when a collect call request message (a message including a communication number of a calling terminal) is received from a calling terminal that has completed the service subscription (S40), the service server sends an advertisement to the calling terminal that requested the collect call. While continuously transmitting, a change in the free talk time according to a change in the degree of the transmitted advertisement is transmitted to the calling terminal (S41). In other words, the more advertisements you receive, the more free calls you get.

Each advertisement transmitted at this time is inserted with a command sending portion for automatically sending a rejection of the next advertisement.

Therefore, after receiving an advertisement transmission rejection command from the calling terminal (S42), the service server terminates the advertisement transmission and informs the total free call time finally calculated (S43).

Next, the service server calls the receiving communication number provided from the calling terminal (S44), and inquires whether the called terminal receives the collect call (S45). When the service server inquires whether the collect call is received, the service server provides the receiving terminal with personal information stored in the database in association with the communication number of the calling terminal that requested the collect call. Helps to determine whether to receive.

If an acknowledgment (ACK) of accepting the collect call is received from the receiving terminal (S46), the service server connects a call path between the calling terminal and the receiving terminal to allow a call to be made between the two terminals (S47). .

During the call between the two terminals, if the free call time according to the receipt of the advertisement is exceeded (S48), the service server informs the calling terminal or the receiving terminal that the free call time has been exceeded (S49). At this time, as a method of informing the free call timeout, a warning signal is transmitted to both terminals, so that an alarm sound is output from each terminal or an alarm message is displayed.

Then, if the call is terminated when the free call time is exceeded and the call is terminated (S50), the service server calculates the paid call fee for the terminated call (S51). At this time, the calculated call rate is an amount obtained by subtracting the free call rate according to the advertisement transmission to the calling terminal from the service use rate proportional to the actual call time, and the reduced amount is notified to both terminals (S52). In addition, the calculated call rate is transmitted to the charging center to update the receiving terminal subscriber database for charging (S53).

According to the method of the collect call service of the present invention described above, in the collect call service of the receiver charged the call charge according to the use of the call service, since the call charge is reduced as much as the advertisement received, the call charge burden of the receiver is significantly reduced. It has the effect of being resolved.

Therefore, when a collect call call is requested, the number of times a call is rejected by the receiver according to the charge of the call can be reduced, thereby increasing the service revenue and increasing the number of subscribers.

Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
