Voice Call Originating Method For Zone-Discount Service In WCDMA Network

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voice call origination method of a regional discount service, and more particularly, to a method for processing a voice call when providing a local discount service among intelligent network services in a WCDMA UMTS mobile telephone network.

In general, the regional discount service is one of the intelligent network services, which sets a zone as a discount zone, and allows the subscriber to register the set discount zone at the time of joining the service so that the call rate is applied differently from the discount zone registered by the subscriber. As a ZoneBased billing service, when a subscriber makes a call in this area, the subscriber can provide the subscriber with a specific tone or announcement so that the subscriber knows that it is a pre-registered discount zone call.

In general, regional discount service can be divided into service for specific subscribers such as youth and home subscriber service (HomePhone service). It is defined as an area of base station units that includes a large number of universities and neighborhoods with high activity.

The service for general subscribers is a service that allows subscribers to designate the area where they talk mainly in the late-night time zone, and applies the billing rate differently when calling from the region registered in the late-night time zone.

That is, a service for a specific subscriber always performs service when calling from a registered area regardless of time, but a service for a general subscriber manages the service time in the system only when the time condition and local condition are satisfied. There is a difference in performing the service.

The call processing process for providing a service to a specific subscriber is described as follows.

1 is an exemplary view illustrating a call processing process for providing a conventional regional discount service. As shown in FIG. 1, when a subscriber subscribes to a regional discount service, the customer information system / customer information distribution system (COIS / CDS) is a home location register. The local discount service is registered with (HLR), and the local discount service registration fact and the local discount zone information of the subscriber are registered with the service control point (SCP) (S100).

Thereafter, the HLR and the SCP respond to the result of the regional discount service registration processing to the COIS / CDS (SCP manages the regional discount zone information of the subscriber in the regional discount DB) (S101).

The HLR sets a local discount service field in the subscriber DB, sets an origination trigger as a K-digit trigger in the QualificationDirective Invoke, and transmits it to the MSC. In addition, the HLR adds a service access code (SAC) to be transmitted to the MSC in a local discount service operation in a routing number table (S102).

The MSC transmits qualdir to the HLR, and when the local discount service subscriber attempts to send, the MSC detects an Origination Trigger and transmits an OriginationRequest Invoke, which is a message, to the HLR (S103 to S104).

The HLR transmits a message OriginationRequestReturn Result to the MSC by adding a SAC to the front of the digits when receiving the message OriginationRequest Invoke to the local discount service subscriber (S105).

In the process of analyzing the received SAC, the MSC recognizes a service access code for processing a regional discount service and transmits an Analyzed Information Invoke to the SCP including the caller's location information (MSCID, LAID) (S106).

The SCP sends a PageRequest Invoke to the gateway HLR to determine the sender's exact current location. The gateway HLR delivers a PageRequest Invoke to the HLR accommodating the subscriber's station number, and the HLR transmits a PageRequest Invoke to the MSC roaming the subscriber (S107).

PageRequest Return Result including subscriber's current location information (MSCID, LAID) is transmitted to MSC-> HLR-> Gateway HLR-> SCP in reverse order (S108).

The SCP checks the location information of the subscriber received from the HLR in the DB and transmits an AnalyzedInformation Return Result to the MSC according to the result. In the case of a call in a regional discount zone, the SCP sets DMH_RedirectionIndicator to the regional discount, sets the announcement code corresponding to the successful regional discount service, and sets the actual called number in the Term List. If the call is not within the regional discount zone, only the actual called number is set in the Term List without DMH_Redlnd and the announcement code (S109).

The MSC attempts to receive the call while providing the caller with the announcement corresponding to the announcement received from the SCP. When the call is normally made and the billing data is generated, the DMH_Redlnd value received from the SCP is stored in the WinService field of the billing CDR as it is (S110).

However, the regional discount service is provided only in a synchronous second generation mobile communication network (2G network), and there is a problem that cannot be applied in a communication network in which an asynchronous third generation mobile communication network (3G network) is mixed.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the subscriber to use the intelligent network (CAP) trigger function at the time of transmission to query the originating location to the SCP, the SCP to the caller in the discount area The purpose of the present invention is to provide a method for notifying the discounted area and indicating the discounted area currency in the billing data (CDR) so that the COIS can be discounted.

Referring to FIG. 3, the mobile station transmits a location registration request message including a subscriber number to a calling MSC (hereinafter referred to as 'OMSE-r') 250 to perform a location registration request (S201). The OMSC-r 250 transmits the location registration request message to the HLR 230 (S202). Accordingly, the HLR 230 determines whether the subscriber is currently located in another mobile telephone network (roaming), and if it is determined that the subscriber is in another mobile telephone network, if the subscriber subscribes to a local discount service, the service can be processed by the corresponding SCP 240. The service trigger information is transmitted through an insert subscriber data (ISD) message (S203). The OMSC-r 250 transmits a response message to the ISD message to the HLR 230 (S204). Accordingly, the HLR 230 transmits a response according to registration to the OMSC-r 250 (S205), and the OMSC-r 250 transmits a message according to the location registration response to the mobile terminal (S206).

After registration, when the originating subscriber attempts to originate (S210), the OMSC-r 250 transmits an Initial DP operation to the SCP address according to the service trigger information received from the HLR 230 in the location registration step. (S211). Parameters included in the above are the service key, the EventTypeBcsm and the location information (LocationInformation) of the calling subscriber.

Upon receiving the Initial DP operation, SCP 240 first determines whether the call is from a discount area registered by the subscriber based on the service key and the subscriber location information.

According to this determination, the SCP 240 transmits a EstablishTemporaryConnection operation, which is a message including an IP address to which an announcement is broadcasted if the discount area is transmitted from the subscriber's area, to the OMSC-r 250 (S212), and the IP (260). ) Includes a CorrelationID in the AssistingSSPIPRoutingAddress parameter that distinguishes the subscriber from the SCFid that is needed to make an announcement query to SCP.

The MSC 250 receiving the IP address for transmitting the announcement to the regional discount subscriber prepares to transmit the announcement by setting up a call path with the IP 260 using the ISUP.

The IP 260 transmits an AssistRequestInstruction operation to the SCP 240 determined from the SCFld, including a CorrelationID included in an Initial Address Message (IAM), and requests an instruction for announcement to be transmitted to the subscriber ( S213).

Accordingly, the SCP 240 transmits the PlayAnnouncement operation, which is the announcement code message including the announcement type in the ElementaryMessageID parameter, to the IP 260 (S214).

The IP 260 transmits the announcement through the connected communication channel, releases the connection with the MSC 250 in the communication, and transmits the SpecializedResourceReport operation, which is the announcement message, to the SCP 240 (S215). .

Subsequently, the SCP 240 that detects the completion of the announcement broadcast transmits a Continue operation to instruct the MSC 250 to continue the call signal processing procedure (S216).

After performing the general call processing procedure, when the local discount subscriber completes the call, the MSC 250 generates the CDR including the service key (S217 to S220).

Figure 4 is an exemplary view showing a discount area voice call origination call processing procedure of the regional discount service according to the origination in the mobile phone network of the present invention.

Referring to FIG. 4, the mobile station transmits a location registration request message including a subscriber number to a calling MSC (hereinafter referred to as 'OMSC') 250 to perform a location registration request (S301). The OMSC 250 transmits the location registration request message to the HLR 230 (S302). Accordingly, the HLR 230 determines whether the subscriber is currently located in the company's mobile phone network, and if the subscriber is determined to be in the company's mobile phone network and subscribes to a regional discount service, the service trigger information is related to the service so that the service can be processed by the HLR and SCP. It is transmitted through an (Insert Subscriber Data) message (S303).

The OMSC 250 receives the ISD message and transmits a response message to the HLR 230 (S304). Accordingly, the HLR 230 transmits a response according to registration to the OMSC 250 (S305), and the OMSC 250 transmits a message according to the location registration response to the mobile terminal (S306).

After registration, if the caller in the OMSC 250 attempts to make a call from the company's mobile telephone network (HPLMN) (S310), in accordance with the service trigger information received in the location registration step, Initial DP operation to the HLR 230 including the relevant parameters It transmits (S311). Accordingly, the HLR 230 confirms that the calling subscriber is a local discount service (TTL) subscriber, and then adds a TTL SAC to the called party dialed by the calling subscriber and transmits a Connect operation to the OMSC 250 (S312).

Then, the OMSC 250 determines the local discount service access code number when translating the incoming number received through the Connect operation, and transmits an Initial DP operation to the SCP address downloaded from the HLR 230 including the relevant parameters ( S313), and the SCP 240 receives the PlayAnnouncement, which is an announcement code message including the type of announcement in the ElementaryMessageID parameter so that the OMSC 250 can send the ConnectToResource operation that is a resource allocation request message and the announcement in the OMSC 250. The operation is transmitted (S314 to S315).

Accordingly, after transmitting the announcement, the OMSC 250 transmits the SpecialzedResourceReport operation, which is the announcement announcement result message, to the SCP 240 (S316).

The SCP 240 transmits the OMSC 250 to the OMSC 250 by including the number in which the SAC code is deleted in the Connect operation for the incoming call processing (S317).
