Description

A method for billing time control based on AIN for next generation intelligent network service}

The present invention relates to a billing processing method in a next generation intelligent network service, and more particularly, to a method of controlling a billing time for a voicemail function.

Representative services that perform voicemail functions among the recently proposed next-generation intelligent network services include TMS service (Telephone Mail Service) and UPT service (Universal Personal Telecommunications). The TMS service is a service that notifies the subscriber later if the caller leaves a voice or number when the subscriber's status is busy or does not answer. The voicemail function is basically provided. In the UPT service, when a subscriber registers a voicemail box, the voicemail box function operates according to the registration condition.

However, as the charging method of the currently provided intelligent network service, if the user does not want to use the voicemail in the TMS and UPT service, for example, even if the user disconnects without leaving a voice message or number, there is a problem that the billing is unconditionally charged.

This is because it is not possible to adjust the timing of transmission of ANM message (Answer Message) transmitted from the transit switch to the single station exchange. In other words, when the ANM message is sent, the billing proceeds.

The present invention devised to solve the above problems is to provide a charging time control method in the next-generation intelligent network service that is properly charged according to the user's intention in providing the next-generation intelligent network service.

10: caller 20: calling station exchange

30: intelligent network service exchanger 40: intelligent network service controller

50: intelligent information providing device 60: destination station exchange

70: incoming contractor

In order to achieve the above object, the present invention includes the following three functions as the charging function.

Function 1. It transmits only ACM (Address Complete Message) message including billing information from SSP (Service Switching Point) to single station exchange.

Function 2. Adjust the timing of ANM message transmission to start charging from the SSP to the end exchange.

Function 3. Transmit ANM received from large station to single station exchange.

Of the above three functions, functions 1 and 2 are required to perform the billing process after listening to the user's use response when performing the voice mail function, and function 3 is required for the billing generally used in functions other than the voice mailbox.

The Intelligent Network Application Protocol (INAP) operation used in this billing method is FCI (FunishCharging Information) and requires additional parameters to distinguish FCI, FCI_ACM, and FCI_ANM to perform the above functions. This parameter distinguishes the above three functions and serves to direct SCP (Service Control Point) to SSP.

The FCI, FCI_ACM, and FCI_ANM used here are all the same FCI operation. In addition, this is classified according to the meaning of the added parameter, and has the following meaning.

. FCI_ACM: Charge information (charge, no charge) is sent to ACM and charging does not start. Subsequent ANMs are ignored and are not sent to the exchange.

. FCI_ANM: Sends ANM to single station exchange and starts charging from this time. As a precondition, the SSP should receive the FCI_ACM and send an ACM message to the terminal exchange.

. FCI: ACM and ANM transmitted from the large station are immediately transmitted to the single station exchange.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a structural diagram of an intelligent network service providing system to which the present invention is applied.

The intelligent network providing system according to the present invention includes a general or public telephone 10, an outgoing end station switch 20 (LE) to which the phone belongs, and a destination end station switch 60 (LE) to which the end station switch 20 and the destination contractor belong. It consists of an intelligent network service controller 40 (SCP), an intelligent information provider 50 (IP), and a terminating contractor 70, which are connected and switched through the intelligent network service exchanger 30 (SSP).

The calling party switching center 20 (LE) plays a role of relaying it to the intelligent network service exchange when a user attempts an intelligent network service call in a general or public telephone, and then collects and transmits the calling number from the calling user when the SSP requests the calling number. .

The intelligent network service switcher 30 (SSP) recognizes that the incoming call is an intelligent network call and performs the function of collecting and exchanging information necessary for the service through interworking with the SCP, and the intelligent network service controller 40 has service logic and data to process the service. Oversee the entire process.

The intelligent information provider 40: SCP performs a function of transmitting and recording a guide broadcast when providing a service. The destination switching center 60 (LE) displays <TMS Service Access Code (SAC) + Status Code (Calling S1 or No Answer S2) + Area Code + Contractor Number> when the destination contractor is busy / no answer when performing TMS service. Form and transmit to the SSP (30). When the SSP 30 receives this and recognizes the intelligent network call and transmits it to the SCP, a procedure corresponding to the TMS service is performed.

FIG. 2 is a process flow diagram of an embodiment of a method of providing a charging function in a TMS service according to the present invention, and will be described with reference to FIG. 1.

In Fig. 2, the caller attempts to receive a call by pressing the called number (arrow 1). However, when the called party is busy and does not answer (arrow 2), the caller recognizes that the TMS subscriber is in the called terminal exchange and recognizes the service identification number, status code value and area code. The contractor number is transmitted to the SSP 30 (arrow 3). The SSP 30 recognizes that it is an intelligent network and sends an IDP operation to the SCP to drive the TMS service logic (arrow 4).

SCP 40 transmits RRBE (RequestReportBCSMEvent) operation for status management, EstablishTemporaryConnection (ETC) operation for IP connection, and FCI operation for providing charging information to SSP 30 simultaneously or sequentially. At this time, the parameter in the FCI operation indicates the meaning of FCI_ACM in order to transmit only the charging information to the single station exchange (arrow 5). Receiving the FCI_ACM operation, the SSP 30 transmits an ACM message including charging information to the single station exchange (arrow 6). Receiving the ETC operation, the SSP 30 connects the bearer channel with the IP (arrow 7), and the IP waits for a command for performing the voicemail function (arrow 8).

SCP 40 collects a selection number for voice recording or leaving a number by sending a PromptAndCollectUserInformation (PCUI) operation to IP (arrow 9). At this time, the ANM message transmitted from the IP to the SSP 30 is ignored by the SSP 30 due to the already transmitted FCI_ACM operation (arrow 10), and the ANM message is transmitted to the end-station only when the FCI_ANM operation is received. (Arrows 14, 15). The FCI_ANM operation is sent from SCP 40 to SSP 30 only when the user selects a number to use voicemail (arrows 13 and 14).

After the number is selected, the SCP 40 transmits the FCI_ANM operation for charging start to the SSP 30, and the PromptAndReceiveMessage (PRM) operation for recording guidance (if voice recording is selected) to the IP (arrow 16). When the voice recording is completed (arrow 19), a call release procedure is performed (arrows 20, 21, 22, 23), and a billing record is generated after the call is completely terminated. At this time, the start time recorded in the charging record is the time when the ANM message is transmitted to the single station exchange by the FCI_ANM operation.

3 is a flowchart illustrating an embodiment of a method for providing a charging function in a UPT service according to the present invention, which will be described with reference to FIG. 1.

In FIG. 3, a function of an FCI operation for performing a general billing and a billing processing function for a voice mail function are simultaneously shown. For the UPT contractor number dialed by the caller, SCP 40 simultaneously or sequentially performs operations for requesting status report (RRBE), billing information provision (FCI), and CONNECT to SSP 30 after translation of the number. Transmit (arrow 28). In this case, the transmitted FCI operation means that the ACM and ANM are transmitted to the single station exchange as soon as they are received from the large station without the need of adjusting the ANM transmission timing. If you report the incoming caller's non-answering / calling to SCP (40) with ERB operation, the operation of the voicemail function afterwards proceeds in the same way as shown in the TMS service (arrows 34 to 52). The billing operation uses FCI_ACM and FCI_ANM.

As described above, the present invention improves the problem of not being able to freely control the time point at which charging such as voicemail function is made by the existing charging method. In the case of a voicemail, if the call is terminated without leaving a voice recording or a number, the disadvantages received by the customer are improved by charging only when the number is selected without charging.

On the other hand, the present invention is not limited only to the above-described embodiments, but may be modified and modified without departing from the scope of the present invention.
