Real-time call processing method and system for voice-video switching service {METHOD AND SYSTEM FOR REAL-TIME CALL TERMINATION CHARGE HANDLING ABOUT SCUDIF}

The present invention relates to a method and system for processing real-time incoming billing for a voice-video switching service. In particular, the present invention relates to a method and system for performing real-time incoming billing processing for voice-video switching service in intelligent network incoming billing 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 (3rd Generation Project). It is a trend to develop technical specifications by forming groups.

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, telecommunications operators are one of a variety of services to expand their business, and provides a billing service.

Incoming billing service refers to a service that allows a caller to make a call free of charge by paying a charge incurred for an incoming call.

For example, the telecommunication service provider assigns a representative number (for example, 080) for the billing service separately to an existing phone number of the billing service subscriber, and charges the caller a charge of a call received through the subscriber's existing phone number or the caller. Charges for calls received through the representative number can be charged to the subscriber as the called party.

However, as mentioned above, since the user does not have a video call service and a voice call service, there is a demand for a subscriber billing method according to the voice-video switching service and the voice-video switching service.

Accordingly, the present invention has been made to solve the above-mentioned requirements, and a method and system for processing real-time incoming billing for a voice-video switching service capable of converting a video call to a counterpart and a video call during voice call processing and, conversely, converting to a voice call during video call processing. It is to provide.

In addition, another technical problem to be achieved by the present invention is a real-time incoming billing processing method and system capable of real-time separate processing for voice billing rates and video billing rates when using the voice-video call transfer service in the intelligent network incoming billing service It is to provide.

In order to solve the above technical problem, a method for processing a real-time incoming charge for the voice-video conversion service by the exchange interoperating with the destination terminal of the intelligent network subscriber according to an embodiment of the present invention,

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

a) receiving a message according to service switching from an exchange after establishing a call with voice or video between a calling terminal and a called terminal of a subscriber registered to the voice-video switching service; And b) calculating the incoming charge based on the existing call end time and the new call start time obtained through the message according to the service switching, and transmitting the called charge information according to the calculated result to the called exchange.

On the other hand, the system for processing the incoming call charge for the voice-video conversion service according to an embodiment of the present invention,

And service switching have the same meaning.

Now, a method and a system for processing real-time incoming billing for a voice change video 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 an incoming billing processing system according to an exemplary 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, and transmits the call to the calling terminal 11 and the called terminal 12 according to the calling party or called party type. 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 incoming billing service, and the service type includes a voice call service, a video call service, and a switching service. And the like.

Intelligent network SCP (200) is a system for performing real-time incoming billing 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.

In other words, the intelligent network SCP (200) provides the exchange charge information according to the result of the real-time incoming charge processing by the service switching through the exchange 300 and the exchange 300. Here, the incoming billing information is required information for the incoming billing processing in the exchange 300, the billing number, billing type (called billing), video or audio call processing type, caller ID, called number, incoming billing service information, rate At least one of the 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 the service switching time point to the intelligent network SCP 200, and transmits incoming charging data (Call Data Record, CDR) according to the incoming charging processing result. Creates and notifies WISE (Wireless Information System Environment) (not shown).

At this time, the exchange 300 may receive the charge information according to the incoming charge processing result from the intelligent network SCP (200) to generate a separate charge billing data (CDR) for each voice and video call service interval.

Meanwhile, a method of processing real-time incoming billing for the switching service according to an embodiment of the present invention will be described with reference to FIG. 2.

2 is a flowchart illustrating a real-time incoming billing processing method for a switching service according to an exemplary embodiment of the present invention.

Referring to FIG. 2, it is assumed that a real-time call charging processing method for a switching service according to an exemplary embodiment of the present invention attempts to call a callee's call forwarding number subscribed to a call forwarding service.

The called billing number may be distinguished by a representative number such as 080, but is not limited thereto and may be another representative number promised in advance in order to provide a called billing service.

(Calling) exchange 300 sets up a separate traffic channel for call switching with the calling terminal 11 when the caller attempts a call through a call forwarding number (eg, 080-123-XYXY) for the call charging service. In addition, the called billing number is set to N-CSI (Number-CSI, triggering according to a specific number (here, N-CSI is registered for 080 representative numbers) as intelligent network trigger information in the number translation step when transmitting an intelligent network call processing). Check that it is set. When the called billing number is set to N-CSI, an IDP (Initial Detection Point) message is transmitted to the intelligent network SCP 200 for intelligent network processing (S201).

At this time, the IDP message has service key information of the intelligent network incoming billing service and BC1 (Bearer Capability) corresponding to voice and BC2 (Bearer Capability) corresponding to 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.

Intelligent network SCP (200) retrieves the actual incoming number assigned to the incoming billing number (080 representative number) to process the incoming billing service (S202), the event generated during the call processing process for the retrieved actual called number (Event) A request report BCSM event (RRBE) message is transmitted to the exchange 300 to set an event necessary for the process report to the exchange (S203).

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 service switching request of the subscriber station 10 from the originating / receiving exchange 300.

In addition, the intelligent network SCP 200 assigns the actual called number to the Connect message and transmits it to the (called) switch 300 to perform incoming call processing, thereby making a new call between the calling terminal 11 and the called terminal 12. Is set (S204).

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. (S205).

When the intelligent network SCP 200 receives the response event (ERB (oAnswer)) message, the charging information required for the charging processing (charge number, charging type (incoming charging), call processing type (video call), call number, incoming call) Number, incoming billing service information, etc.) is assigned to a Furnish Charging Information (FCI) message in order to be reflected in the incoming billing data (CDR) and transmitted to the (called) exchange 300 (S206).

At this time, the FCI message is generated at the time of service change (Service Change) when the call is connected or responded to by the destination terminal 12 is transmitted to the (called) exchange 300, and after the service switching process FCI for each bearer respectively Assign.

Thereafter, the (incoming) exchange 300 generates incoming billing data (CDR) based on incoming billing information for each service section after receiving the FCI according to the service change, and the incoming call for each section in the WISE (Wireless Information System Environment) Use this to settle incoming charges based on your billing data (CDR).

On the other hand, when a voice-video call transfer occurs by the called terminal 12, the (called) exchange 300 generates and transmits a service change event (ERB) message according to the call transfer to the intelligent network SCP (200) (S207). ).

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 service switching event (ERB) message, calculates the incoming charge 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, the intelligent network SCP (200) according to the received service switching event (ERB), the billing number, billing type (incoming billing), call processing type (video call), call number, called number, incoming billing service information, etc. In order to reflect the information on the incoming billing data (CDR), the information is allocated to the FCI (BC1-voice) message and transmitted to the (called) exchange 300 (S208).

On the other hand, if the voice-video transfer occurs again by the terminating terminal 12, similar to the steps S207 and S208 described above (singing) switch 300 is a service switching event for the transfer to the intelligent network SCP ( ERB) generates and transmits a message (S209).

And, intelligent network SCP (200) according to the received service transition event (ERB) charge number, charge type (incoming charge), call processing type (voice call), incoming number, incoming number, incoming charge service information, etc. In order to reflect the information on the incoming billing data (CDR), it is assigned to the FCI (BC1-voice) message and transmitted to the (called) exchange 300 (S210).

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 (S211), and transmits the Release message to the exchange 300 to terminate the call processing End the call (S212).

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 caused 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.

As described above, according to the present invention, when the voice-video call transfer service is used in the intelligent network incoming billing service, there is an effect of enabling the real-time division processing for the voice billing rate and the video incoming billing rate.

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 the billing settlement can be separately processed for each service converted section through the generated CDR.

That is, the voice-video switching service can handle multiple service conversions during call processing, and generates a CDR each time the service switches to handle incoming call charges separately, thereby processing accurate incoming charges according to the subscriber's service change. You can expect the effect.

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.
