Description

Real-time location-based billing processing method and system for voice-video conversion service {METHOD AND SYSTEM FOR REAL-TIME CHARGE HANDLING BASED ON LOCATION ABOUT SCUDIF}

The present invention relates to a method and system for real-time location-based charging for voice-video switching services. In particular, the present invention relates to a method and system for performing real-time location-based billing processing for voice-video switching service in an intelligent network location-based billing discount service.

In general, wideband code division multimedia access (WCDMA) systems support not only voice but also video call services, which are high-definition video services.

With the development of mobile communication technology, data to be transmitted in wireless communication networks is gradually increasing in volume, and a necessity for transmitting large data at high speed without error is required. In response to these demands, a WCDMA system has been developed to improve the data transfer rate. WCDMA system was developed for the purpose of multimedia data transmission, and it is different from many existing systems such as high-definition video service and fast data rate. Currently, many organizations such as Korea, Europe, Japan, USA, and China have 3GPP It is a trend to develop technical specifications by forming a group.

In the WCDMA system, a voice call and a video call operation method select a voice or video call mode when an initial call is set up according to a user's request of the calling terminal, and the called terminal selectively connects depending on whether the video call mode is supported when the initial call is set up. Will be.

However, if the called terminal is in an environment where video calling is impossible or is not supported as a service, even if the calling terminal requests a video call, the called terminal may receive a service by a voice call or may not be serviced.

That is, when the called terminal is unable to make a video call, there is a function of setting a call between the calling terminal and the called terminal as a voice call by a mobile switching center (MSC) during call setup. There is no way to switch services at the request of the company. Therefore, even if a user does not need a video call, a relatively expensive video call fee is charged, and when a user wants to switch to a video or voice call during a call, the user needs to hang up and reconnect again. have.

On the other hand, mobile communication providers are providing a zone-based zone service as one of various services to expand their business network.

Zone service is a service to provide a separate service that is distinguished from other regions in a specific region (area), and it is free to determine whether it is located in a specific zone based on the subscriber's mobile phone location information. Or provide a service such as a discount rate.

That is, the use of the service provided in the zone service area may be applied to a differential fee such as free or a discount based on the fact that the subscriber is located in the zone service area during a signaling process for call setup.

However, as mentioned above, since the user does not have a video call service and a video call service, the billing processing method based on the subscriber's location information in the zone service area according to the voice-video switching service and the voice-video switching service is provided. This is required.

Accordingly, the present invention is to solve the above-mentioned requirements, the real-time location-based billing processing method for the voice-video conversion service that can be switched to the other party and the video call during the voice call processing, and, conversely, to the voice call during the video call processing and It is to provide a system.

In addition, another technical problem to be achieved by the present invention is a real-time for the voice-video conversion service that can be processed in real time for the voice charge rate and video charge rate when using the voice-video call transfer service in the intelligent network location-based charging discount service To provide a location-based billing processing method and system.

In order to solve the above technical problem, a method for processing a real-time location-based billing for voice-video switching service by the exchange interworking with the terminal of the intelligent network subscriber according to an embodiment of the present invention,

a) switching a connected call when the subscriber's calling terminal and the called terminal receive a service switching request from the calling terminal or the called terminal after setting up a call with voice or video; b) transmitting a message according to the service switch request to an intelligent network service controller supporting location based discount service of the intelligent network; And c) receiving charging information according to the charging discount processing result of the intelligent network service controller and generating separate charging data for each voice and video call service section.

On the other hand, the intelligent network service controller supporting the location-based discount service according to an embodiment of the present invention to process the real-time location-based billing for voice-video conversion service,

a) receiving a message according to the service switching request from the exchange after the calling terminal and the called terminal of the subscriber set up a call by voice or video; b) determining whether the location of the calling terminal exists in a service zone pre-registered for the subscriber's location-based discount service; And c) transmitting charging information according to the charging discount processing result based on the determination to the exchange.

On the other hand, a system for processing real-time location-based billing for voice-video conversion service,

A home location register reflecting information stored in the information on the mobile network service subscription and storing subscriber profile information for the voice-video switching service; A switch for switching a call according to a service switching request of an originating terminal or a called terminal and transmitting a message reporting the service switching to an intelligent network service controller; And an intelligent network service controller configured to determine whether a location of the calling terminal exists in a pre-registered location-based discount service zone when receiving a message reporting a service switch, and calculate a billing based on the determined result.

According to the above configuration, when using the voice-video call transfer service in the intelligent network location-based charging discount service, the voice charging rate and the video charging rate can be processed in real time. In addition, it is possible to generate a separate billing CDR for each section for the use of the voice-video call transfer service, and has an effect of separately processing the call history and billing settlement through the generated billing CDR.

In addition, the voice-video conversion service can be switched many times during call processing, and generates a CDR each time to handle billing separately, so that accurate billing can be processed based on the subscriber's call transfer and location. have.

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.

Now, a real-time location-based billing processing method and system for a voice-video switching service (Service Change and UDI Fallback, SCUDIF) according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram schematically illustrating a network configuration of a billing processing system according to an embodiment of the present invention.

Referring to FIG. 1, an audio-video switching service system according to an embodiment of the present invention includes a home location register (HLR) 100, an intelligent network service controller (Service Control Point, SCP) 200, and the like. A switch (Mobile Switching Center, MSC) 300 and the subscriber station (10).

First, the subscriber station 10 is a terminal capable of providing a WCDMA voice-video switching service to a subscriber subscribed to a mobile communication service and an intelligent network service. May be referred to.

In addition, although not shown in FIG. 1, the subscriber station 10 accesses a WCDMA network through a base station and a Radio Network Controller (RNC), and transmits a mobile station (MS), a mobile terminal (MT), and a subscriber station (Subscriber). Station (SS), Portable Subscriber Station (PSS), User Equipment (User Equipment, UE), Access Terminal (Access Terminal, AT), etc., may be referred to as a mobile terminal, subscriber station, portable subscriber station, It may also include all or part of the functionality of the user device.

The HLR 100 stores the intelligent network service subscription information in the mobile communication service subscriber (hereinafter, used in the same sense as the 'intelligent network service subscriber') information and stores the customer profile information for the voice-video conversion service. Manage.

In this case, CAMEL Subscriber Information (CSI) of the mobile communication service subscriber subscribed to the intelligent network service is set in the subscriber profile information. Here, the Camel reservation information includes an intelligent network service key (Service Key), a service type, and an address of the intelligent network SCP (200) for the subscriber's location-based discount service (zone service), and the service type includes voice call service and video. Call services and divert services.

Intelligent network SCP (200) is a system for performing a real-time location-based billing discount processing for voice-video switching service according to an embodiment of the present invention, and manages profile information on whether to provide a switching service according to the service type.

That is, the intelligent network SCP 200 provides the exchange 300 with the charging information according to the real-time location-based charging discount processing result by the service switching through the exchange 300. Here, the billing information includes at least one of a billing number, a billing discount type (location-based discount), a video or audio call processing type, a calling number, a called number, a discount / discount, and rate information.

The switch 300 serves as a WCDMA switch to serve as an originating switch 310 or a destination switch 320 according to the operation type of the subscriber station 10 in the management area, and has a voice, video, SMS call processing function and a subscriber station. Manage VLR (not shown) information for managing the location registration function and subscriber profile of (10).

The exchange 300 sets up a separate traffic channel for the subscriber terminal 10 and voice and video for the voice-video call conversion of the subscriber, respectively, and the originating or terminating subscriber terminal 10 uses the voice as the image and the image. If a request to switch to voice is made, the selected traffic channel is used for call transfer.

In addition, the exchange 300 interworks with the intelligent network SCP 200 to report the occurrence of an event corresponding to a service switching time point to the intelligent network SCP 200, and charge data according to the location-based charging discount processing result (Call Data Record, CDR). It generates a function to notify the WISE (Wireless Information System Environment) (not shown).

In this case, the exchange 300 may generate charging information (CDR) for each voice and video call service section by receiving charging information according to the location-based charging discount processing result from the intelligent network SCP 200.

Meanwhile, a location based discount service according to an embodiment of the present invention will be described with reference to FIG. 2.

2 is a conceptual diagram illustrating a location-based discount service according to an embodiment of the present invention.

Referring to FIG. 2, the location-based discount service according to an exemplary embodiment of the present invention uses a service in a corresponding zone (eg, campus zone) area while a subscriber of the calling terminal 11 is subscribed to the location-based discount service. In this case, it means that the location-based charging for the calling terminal 11 is differentially charged according to the preset location-based discount policy.

The zone area can be set in units of cells covering a specific area such as a campus zone, and the intelligent network SCP 200 has a cell identification table corresponding to the zone area and cell identification information according to a service call request of the calling terminal 11. It may be determined whether the calling terminal 11 is located in the zone area by comparing the cell identification information table.

The location-based discount policy may be, for example, a voice or video call service, a text service, and a data usage fee between subscribers made in a zone, free of charge, or a discount rate.

In particular, the billing processing system according to an embodiment of the present invention determines whether the subscriber station 10 is located in the zone area when the subscriber station 10 transfers the voice-video call, and processes the charging discount for each section of the voice call and the video call. Can be determined.

Meanwhile, a real-time location-based billing processing method for the conversion service according to an embodiment of the present invention will be described with reference to FIG. 3.

3 is a flowchart illustrating a real-time location-based billing processing method for a switching service according to an embodiment of the present invention.

Referring to FIG. 3, in the real-time location-based billing processing method for the conversion service according to an embodiment of the present invention, a subscriber subscribed to a location-based discount service (eg, a campus zone) calls a call within a corresponding campus zone service area. Suppose you have tried.

(Calling) exchange 300 sets a separate traffic channel for call switching with the calling terminal 11 when the location-based discount service subscriber attempts to call through call originating terminal 11, and the call originating exchange 300 HLR (100) according to O-CSI (Originating-CSI), information for triggering to intelligent network SCP when sending intelligent network call processing, usually triggers when certain conditions (digit number, length, service, etc.) meet digital collection point A service request is made at S301. The O-CSI may include an intelligent network service key for a subscriber's location-based discount service (zone service), voice call / video call service request information, and the like.

The HLR 100 determines the service attribute for the service request received from the (sending) exchange 300 (S302). In addition, when the calling terminal 11 is subscribed to a location-based discount service (campus zone service), an Routing Number (INRN) and a TA (Termination Ack) corresponding to the location-based discount service in a Connect message are identified. ) Is transmitted to the (send) exchange 300 (S303).

The exchange 300 exchanges the intelligent network in the number translation step when the dialed-CSI (Intelligent Network Call Processing) originates from the INRN assigned to the destinationRoutingAddress of the connected message received from the HLR 100. Check that the trigger information is set to a specific Digit (set the trigger according to D-CSI registration for INRN here). When the INRN is set to the D-CSI, an IDP (Initial Detection Point) message is transmitted to the intelligent network SCP 200 for intelligent network processing (S304).

In this case, the IDP message includes service key information of an intelligent network location-based discount service and a BC1 (Bearer Capability) corresponding to a voice and a BC2 (Bearer Capability) corresponding to a video in the case of a voice-video call transfer call.

For example, the parameters included in the IDP message are as follows. If the Ext-BasicServiceCode value is H'11, the voice call processing scenario is executed. If Ext-BasicServiceCode is H'1F, video call processing scenario is executed.

The intelligent network SCP 200 compares the location information of the subscriber originating terminal 11 received from the IDP with the location (zone area) information registered in the intelligent network SCP 200 to process the location-based discount service, and then the originating terminal 11. Check whether this is in the registered same zone (S305). Then, according to the result of checking whether the same zone exists, whether or not the discount or discount is notified to the (send) exchange 300 (S306). Here, the intelligent network SCP 200 may notify the subscriber originating terminal 11 by generating whether the discount or non-discount in the form of voice announcement, USSD (Unstructured Supplementary Service Data) message or text message (SMS).

Next, the intelligent network SCP 200 transmits a request report BCSM event (RRBE) message to the exchange 300 to set an event necessary for reporting an event generated during the call processing. (S307). The event occurrence report request message includes a Service_Change DP (Detection Point) for reporting an audio-video transfer service event. The Service_Change DP means an event detection point that the exchange 300 will report to the intelligent network SCP 200 during the intelligent network call processing. Therefore, the intelligent network SCP 200 may receive a voice-video transfer event generated by the request of the subscriber terminal 10 from the originating / receiving exchange 300.

In addition, the intelligent network SCP (200) assigns the actual called number to the Connect (Connect) message to transmit to the (called) switch 300 to perform the incoming call processing.

Meanwhile, when the called terminal 12 responds to the service request, the (called) exchange 300 transmits an event report BCSM (oAnswer) message according to the response of the called terminal 12 to the intelligent network SCP 200. (S308).

When the intelligent network SCP 200 receives the response event (ERB (oAnswer)) message, the billing information (billing number, billing type (location-based discount), call processing type (video call), origination number) according to the location-based billing discount processing result In order to reflect the charge number, charge discount, etc.) in the billing data (CDR), it is assigned to a Furnish Charging Information (FCI) message and transmitted to the (send) exchange 300 (S309).

At this time, the FCI message is generated at the time of service change (Service Change) or transmitted to the (calling) exchange 300 in response to the destination terminal 12, and the FCI for each bearer after the service switching process, respectively Assign.

Subsequently, the (send) exchange 300 generates billing data (CDR) based on billing information for each service section after receiving the FCI according to a service change, and billing data for each section in a wireless information system environment (WISE). Based on CDR).

On the other hand, when a voice-video call transfer occurs by the receiving terminal 12, the (called) exchange 300 generates and transmits a service change event (ERB) message according to the transfer to the intelligent network SCP (200) (S310) ).

The (incoming) exchange 300 transmits a service change event (ERB) message at the completion of a service change (start of a new call after the termination of an existing call), and the existing call (ERB) message is transmitted to the service change event (ERB) message. Video) end time and new call (voice) start time.

The intelligent network SCP 200 analyzes the received call transfer event (ERB) message to calculate billing based on the existing call end time and the new call start time, and assigns the received time to the FCI. At this time, the intelligent network SCP (200) is processed to exclude the new call setup (Setup) time required until the new call start time after the end of the existing call from the billing.

In addition, intelligent network SCP (200) according to the service transition event (ERB) billing number, billing type (location-based billing discount), call processing type (video call), call number, called number, discount / non-discount information, etc. In order to reflect the information on the charge data (CDR), the information is allocated to the FCI (BC1-voice) message and transmitted to the (send) exchange 300 (S311).

On the other hand, if the voice-video transfer occurs again by the terminating terminal 12, similar to the steps S310 and S311 described above (singing) switch 300 is a service switching event for the transfer to the intelligent network SCP (200) ( ERB) generates and transmits a message (S312).

And, intelligent network SCP (200) according to the service transition event (ERB) billing number, billing type (location-based billing discount), call processing type (voice call), billing number, called number, discount / non-discount information, etc. In order to reflect the information to the charge data (CDR), it is assigned to the FCI (BC1-voice) message and transmitted to the (send) exchange 300 (S313).

As described above, when a new service change occurs by the called subscriber, the intelligent network SCP 200 repeats the procedure of allocating the FCI after receiving the ERB (Service Change).

Then, the intelligent network SCP (200) receives the service termination event (ERB (Disconnect)) message from the exchange 300 is terminated call processing (S314), by sending a Release message to the exchange 300 to terminate the call processing End the call (S315).

Although the embodiments of the present invention have been described above, the present invention is not limited only to the above embodiments, and various other changes are possible.

For example, in the exemplary embodiment of the present invention illustrated in FIG. 3, the voice-video transfer is performed by the called terminal 12. However, the present disclosure is not limited thereto, and the voice-video transfer may be performed by the calling terminal 11. Can be.

Therefore, the WCDMA network provides a service capable of converting a video call with a counterpart during voice call processing and, conversely, converting to a voice call during video call processing.

In addition, according to the exemplary embodiment of the present invention shown in FIG. 3, in step S305, whether the calling terminal 11 is in the registered same zone is checked, but not limited thereto. However, the present invention is not limited thereto. By checking the existence of the same (11), it is possible to determine whether the billing discount or non-discount for the service converted call.

As described above, according to the present invention, when the voice-video call transfer service is used in the intelligent network location-based charging discount service, the voice charging rate and the video charging rate can be distinguished in real time.

In addition, it is possible to generate a separate billing CDR for each section for the use of the voice-video call transfer service, and has the advantage that the call history and billing settlement can be separately processed for each service converted section through the generated CDR.

That is, the voice-video switching service can switch several times during the call processing, and generates a CDR each time the service is switched, thereby having an effect of separately charging.

The embodiments of the present invention are not limited to the above-described apparatuses and / or methods, but may be implemented through a program for realizing functions corresponding to the configuration of the embodiment of the present invention, a recording medium on which the program is recorded And such an embodiment can be easily implemented by those skilled in the art from the description of the embodiments described above.
