This is a data flow diagram illustrating a subscriber registration method in Mode.

First, if the customer management system 165 has an application for using an additional service (for example, providing sound source data) using the call waiting time of the mobile communication service subscriber, the customer management system 165 indicates that there is an application for using the additional service for the subscriber. In the database included in the).

Subsequently, in the case where the subscriber of the mobile communication service subscriber is in the form of A-Mode (ie, an additional service type in which the caller registers and the caller uses the service), the mobile communication service is performed through the steps as shown in FIG. 2A. If the subscriber is registered, but in the case of B-Mode (that is, an additional service form where the called party registers and the caller uses the service), the subscriber registers with the mobile communication service through the steps shown in FIG. 2B.

First, referring to FIG. 2A, referring to the registration process of a mobile communication service subscriber in A-Mode, in step 210, the customer management system 165 may include a home location register 135, an intelligent network switch 130, and an additional service control server ( In step 154, the subscriber information registration request (eg, subscriber information generation request, subscriber information deletion request, etc.) is transmitted.

At this time, the subscriber information registration request is transmitted according to the TCP / IP transmission method. In addition, the customer management system 165 operates as a client, and the home location register 135, an intelligent network (not shown), and the additional service control server 154 operate as a server. At 215, the home location register 135 applies for additional service use by the subscriber to the subscriber information of the subscriber stored in the home location register 135, corresponding to the subscriber information registration request received from the customer management system 165. Register that there was.

In step 220, the additional service control server 154 registers subscriber information of the mobile communication service subscriber corresponding to the subscriber information registration request received from the customer management system 165. Thereafter, the customer management system 165 through step 225. ) Receives the subscriber information registration result corresponding to the subscriber information registration request transmitted through step 210 from the home location register 135, the intelligent network switch 130, and the additional service control server 154.

The operation made through the steps 210 to 225 will be briefly described as follows.

In the case of the A-Mode service, the customer management system 165 transmits request information such as a subscriber's creation, deletion, and change to the home location register 135, the intelligent network switch 130, and the additional service control server 154. A response can be received.

Referring to the need for subscriber management for each system, the home location register 135 transmits an outgoing signal received from the user terminal 110 to the intelligent network switch 130, the outgoing signal is sent to the intelligent network through the intelligent network switch 130 The additional service control server 154 is a device for performing subscriber information management for transmitting sound source data, and the subscriber information is substantially transmitted to the subscriber management system (WIN-SCP). It is registered and managed by the additional service control server 154.

Next, referring to FIG. 2B, the registration process of the mobile communication service subscriber in B-Mode is performed. In step 250, the customer management system 165 transmits the subscriber information to the home location register 135 and the additional service control server 154. The registration request (eg, subscriber information generation request, subscriber information deletion request, etc.) is transmitted.

In step 255, the home location register 135 uses the additional service by the subscriber in the subscriber information of the subscriber stored in the home location register 135, corresponding to the subscriber information registration request received from the customer management system 165. Register that the application was made.

In step 260, the additional service control server 154 registers subscriber information of the mobile communication service subscriber corresponding to the subscriber information registration request received from the customer management system 165.

Thereafter, the customer management system 165 receives the subscriber information registration result corresponding to the subscriber information registration request transmitted through the step 250 from the home location register 135 and the additional service control server 154 through step 265.

The operation made through the steps 250 to 265 will be briefly described as follows.

In the case of the B-Mode service, the customer management system 165 may transmit request information such as a subscriber's creation, deletion, and change to the home location register 135 and the additional service control server 154 and receive a response accordingly. In this case, the home location register 135 performs a function of supporting call processing to the additional service providing apparatus 152 via the incoming mobile switching center 125, and the additional service control server 154 performs the B service. -Mode Subscriber to receive the subscriber information from the customer management system 165 to provide services and register and manage.

In addition to the A-Mode service or the B-Mode service described with reference to FIGS. 2A and 2B, the present invention may also be applied in the form of a K-Mode service (ie, an additional service using call waiting time generated by a new concept). In the case of using the present invention in the form of a K-Mode service, the data required for interworking with the additional service providing apparatus 152 as in the above-described case may include the home location register 135, the intelligent network switch 130, and the additional service control. The subscriber information for use of the supplementary service may be stored and managed by the supplementary service control server 154.

3 is a data flow diagram illustrating a subscriber service information and a sound source code registration method according to an embodiment of the present invention.

The subscriber service information and the sound source code registration method shown in FIG. 3 may be commonly applied in A-Mode, B-Mode, K-Mode, and the like. to provide.

In each step, transmission and reception of data is based on a TCP / IP socket transmission method, and the additional service control server 154 operates as a server and the content providing device 180 operates as a client.

In addition, the additional service control server 154 manages only the sound source code, and when the additional service providing device 152 processes the call with the sound source data file, it transmits the sound source data to the corresponding mobile communication service subscriber.

Referring to FIG. 3, in step 310, the additional service control server 154 and the content providing device 180 check a connection state between each system and a target system service operation state.

This is a procedure for connection state management (ie, TCP connection management) in TCP / IP socket transmission, which the additional service control server 154 and the content providing device 180 may request in both directions.

The additional service control server 154 and the content providing device 180 may transmit and receive a status request message from time to time, if necessary to secure the reliability of the additional service using the call waiting time, and, depending on the reliability of the service, The transmission period can be adjusted.

The standard of state management between the additional service control server 154 and the content providing device 180 is a connection with the target system, and for some reason (for example, system abnormality, connection abnormality, and time elapsed) -out), the connection with the target system can be released.

The criterion of the target system is defined as an IP address, and when there are a plurality of connections, step 310 may be performed for each connection state.

In operation 315, the content providing device 180 transmits a query about whether a function is registered and whether a sound source code is registered to the additional service control server 154 through a communication network.

The additional service control server 154 checks whether any function and sound source code requested from the content providing device 180 is already registered in the additional service control server 154 through step 320, and proceeds to step 325. In operation 320, the verification result data regarding the function registration check and the sound source code registration check, which are confirmed in step 320, is transmitted to the content providing device 180 through the communication network.

In other words, step 315 to step 325 is a service querying step, which transmits a query for subscriber authentication / service function registration and sound source code registration.

The additional service control server 154 may selectively transmit the partial information or the entire information of the subscriber information managed for each service in step 330. In step 330, the content providing device 180 moves. The additional service usage request information of the communication service subscriber and / or a request for updating the sound source code (that is, a request for generating a sound source code, a change request, a deletion request, etc.) are transmitted to the additional service control server 154 through a communication network.

The supplementary service control server 154 updates the supplementary service use request information and / or the sound source code of the mobile communication service subscriber to correspond to the service use request information and / or the sound source code update request received through the step 330 in the step 335, In step 340, the updated service usage request information and / or the update result of the sound source code updated in step 335 are transmitted to the content providing device 180 through the communication network.

In other words, step 330 to step 340 is a process of processing an application for additional service use of a mobile communication service subscriber and generating, deleting, or changing a sound source code, and the sound source code is also assigned to each mobile communication service subscriber. By defining as a service attribute of a subscriber, it can be processed in a similar manner to the method of registering subscriber information of the mobile communication service subscriber (see description in FIGS. 2A and 2B).

In addition, if there is no response (Time-out) in the target system after requesting the message in steps 315 to 340 described above, the retransmission algorithm may be performed through step 310. Of course, the stability of the entire system can be improved by limiting the number of connections between target systems.

In addition to the steps illustrated in FIG. 3, the mobile communication network may transmit information about a subscriber information change, a supplementary service use information change, a sound source code attribute change, and the like of the mobile communication service subscriber from the additional service control server 154 to the content providing device 180. And transmitting a response to the information from the content providing device 180.

4 is a data flowchart illustrating a method of registering a sound source data file in an additional service providing apparatus according to an exemplary embodiment of the present invention.

Referring to FIG. 4, in step 410, the additional service providing apparatus 152 and the content providing apparatus 180 confirm a connection state between each system and a target system service operation state.

Since the detailed description associated with operation 410 is the same as that described with reference to operation 310 of FIG. 3, duplicate description thereof will be omitted. In operation 415, the content providing device 180 performs the additional service providing device 152 through a communication network. Sends a request to confirm whether the sound source data file has been registered. Of course, at this time, a confirmation request for additional information such as a registration time as well as whether the sound source data file is registered may be made together.

The additional service providing apparatus 152 confirms whether or not the sound source data file corresponding to the sound source data file registration request received in step 415 is registered, and proceeds to step 420 to confirm whether the sound source data file is registered. The data is transmitted to the content providing device 180 through a communication network.

Referring again to the process of confirming whether the sound source data file is registered through the steps 415 and 420, the content providing device 180 first registers the sound source data file with respect to all the additional service providing devices 152 in order to register the sound source data file. Sends a request for confirmation whether the data file has been registered.

Of course, in this case, if there is a mismatch between the supplementary service providing apparatuses 152 (that is, a mismatch of sound source data file registrations between the supplementary service providing apparatuses 152), a matching procedure is performed. In the case of operating the service providing device 152 by dividing the mobile communication service subscribers based on the telephone number basis (that is, by the subscribers, not by the service, in this case, the service may be jointly accommodated). Steps 415 and 420 may be performed only for the additional service providing device 152 classified for each subscriber.

In addition, the same may be applied to the process of registering the sound source data file or the process of deleting the sound source data file which will be described below.

In operation 425, the content providing device 180 transmits the sound source data file to the additional service providing device 152 through the communication network, and transmits the sound source data file to be registered in the additional service providing device 152. The registration request information of the file is transmitted to the additional service providing apparatus 152.

In operation 430, the additional service providing apparatus 152 stores the sound source data file received together with the database in response to the registration request of the sound source data file received in operation 425.

In operation 435, the additional service providing apparatus 152 transmits registration result data of the sound source data file performed in operation 430 to the content providing apparatus 180 through a communication network.

The sound source data file registration process performed through the steps 425 to 430 will be described once again, which means that the sound source data file registered through the mobile communication service subscriber interface of the contents provider is transferred to the additional service providing apparatus 152. This is a process for transmitting and registering the sound source data file. The method of transmitting the sound source data file is a method of applying only a socket message transmission method, and jointly combining a socket message and a file transfer protocol (FTP). The method of application may be applied.

In addition, when a large amount of sound source data file is transmitted, it may be transmitted using commercial FTP, and a method of requesting registration with a socket message may be applied when a mobile communication service subscriber has a choice.

In the case of applying only a socket message transmission method, the registration request information of the sound source data file and the sound source data file is transmitted through the same connection.

Of course, the sound source data file may be transmitted through a separate connection instead of the same connection with the registration request information of the sound source data file, but in this case, the matched data transmitted through each connection There is a need for an algorithm that ensures gender.

In addition to the sound source data file registration process described above on the data flow diagram shown in FIG. 4, the process of deleting a sound source data file already registered may be further included. However, the process of deleting the sound source data file may include the sound source data file described with reference to steps 425 to 435. Since the registration process is similar to that of the description thereof will be omitted.

FIG. 5 is a data flow diagram illustrating a call processing step from connection in an A-Mode to a supplementary service providing apparatus when a call is made using a user terminal according to an exemplary embodiment of the present invention.

Among the additional service types to which the present invention is applicable, A-Mode refers to an additional service type in which a caller registers an additional service and the caller uses the service.

Referring to FIG. 5, when an originator's user terminal 110 (hereinafter referred to as originating terminal) enters the jurisdiction of any originating mobile exchange 120, the originating mobile exchange 120 proceeds to step 511. The originating terminal registration request is transmitted to the home location register 135 to register the originating terminal.

In step 513, the home location register 135 transmits mobile communication service subscriber information (i.e., caller information) corresponding to the calling terminal registration request in step 511 to the calling mobile switching center 120 through the communication network. ) Stores the caller information received via step 513 in a Visitor Location Register (not shown).

When the outgoing mobile exchange 120 receives a call connection signal for a telephone call with any called party transmitted from any caller's user terminal 110 via step 515, the flow proceeds to step 517 to the intelligent network exchange 130. Send setup request (ISUP IAM) to the call. At this time, the location information of the subscriber of the mobile communication service is transmitted together. In step 519, the intelligent network switch 130 checks whether the caller is an A-Mode Supplementary Service User through an intelligent network subscriber management system (WIN-SCP). The service routing information request (Routing Request) is transmitted to the Wireless Intelligent Network-Service Control Point (510).

In step 521, the intelligent network subscriber management system 510 determines whether the caller is an A-Mode supplementary service user, and proceeds to step 523 in order to route information to the supplementary service providing apparatus 152 (for example, a prefix ( Prefix, Routing Digit, etc.) is transmitted to the intelligent network switch 130 through the communication network. In step 525, the intelligent network switch 130 uses the service routing information received through step 523 to determine the communication network (i.e., No). Transmits a voice channel setting request to the additional service providing apparatus 152 through a network.

The supplementary service providing apparatus 152 selects a sound source data file to be transmitted to the calling terminal in association with the supplementary service control server 154 in step 527, and proceeds to step 529 to provide the intelligent network switch 130 with a channel setup response ( For example, an address complete message (ACM), an answer message (ANM), and the like may be included, and a CON message may be used to simplify the message. This will be described in detail later with reference to FIG. 7.

In step 531, the intelligent network exchange 130 transmits a channel establishment response to the originating mobile exchange 120 through the communication network.

Thereafter, in step 533, the additional service providing apparatus 152 transmits the sound source data file selected in step 527 to the caller terminal through the communication network, and in the caller terminal, the substitute sound corresponding to the sound source data file received in step 533 is received. It becomes Ring-Back Tone.

At the same time, the intelligent network switch 130 transmits a location information request of the called terminal to connect to the called terminal (that is, the called user's user terminal) in step 535.

In step 537, the home location register 135 transmits a Temporary Local Directory Number (TLDN) request for establishing a call to the called mobile switching center 125 where the called terminal is registered.

The incoming mobile switch 125 checks the idle call line and transmits the temporary channel number (TLDN) to the home location register 135 through the communication network in step 539. In step 541, the home location register 135 In step 539, the temporary channel number (TLDN) received from the terminating mobile switcher 125 is transmitted to the intelligent network switch 130 through the communication network.

In step 543, the intelligent network exchange 130 transmits a voice call channel establishment request to the incoming mobile exchange 125 through the communication network.

(ANM: Answer Message), etc.).

Referring again to the destination terminal confirmation operation performed in steps 545 to 547, the destination mobile switch 125 is a base station controller (BSC), a base station coupled with the destination mobile switch 125 through a communication network. The base station transmits a message for searching for a called terminal through a base transceiver station (BTS). When the called terminal responds to the message, the called mobile switch 125 transmits an intelligent network switch 130 through the communication network. When the called party responds to the incoming request, the called mobile switcher 125 transmits an acknowledgment message (ANM) to the intelligent network switch 130.

In step 549, the intelligent network switch 130 transmits a voice channel release request for transmitting the sound source data file to the calling terminal to the supplementary service providing apparatus 152 through the communication network.

The additional service providing apparatus 152 releases the voice channel transmitting the sound source data file to the calling terminal, and transmits the sound source data transmission channel release response message to the intelligent network switch 130 through the communication network in step 551.

Thus, the voice channel for transmitting the sound source data set between the calling terminal and the supplementary service providing apparatus 152 is released, and a call path is formed between the calling terminal and the called party terminal to make a call between them (step 553). Although not shown in the drawing as a step after step 553, when a telephone call between the caller and the called party is terminated, a call for disconnection is transmitted from the originating mobile switch 120 to the intelligent network switch 130 by a disconnect message (REL: Release Message). The method may further include transmitting a truncation message REL from the intelligent network switch to the destination mobile switch 125 to make a truncation request.

Then, the subsequent steps may further include transmitting a Release Complete Message (RLC) from the intelligent network exchange 130 to the originating mobile exchange 120 and from the terminating mobile exchange 125 to the intelligent network exchange. have.

However, when an incoming call to another provider network is required, steps 535 to 541 may be omitted, and may be processed by requesting channel setting from an exchange of another provider network.

Is transmitted to the destination mobile switching center (125) via a communication network.

This allows the destination mobile switcher 125 to store the additional service type and routing information of the mobile communication service subscriber in the visitor location register.

If the outgoing mobile exchange 120 receives a call connection signal for a telephone call with the called party transmitted from any caller's user terminal 110 through step 617, the flow proceeds to step 619 to the home location register 135. A terminal location information request (that is, information on the destination mobile switch in which the called terminal 610 is located) is transmitted.

The home location register 135 searches for an incoming mobile exchange corresponding to the incoming terminal location information request received in step 617, and proceeds to step 621 to transmit a temporary channel number request to the retrieved destination mobile exchange 125.

The destination mobile switch 125 checks the idle call line and then transmits the temporary channel number (TLDN) to the home location register 135 through the communication network in step 623.

In step 625, the home location register 135 transmits the temporary channel number received from the destination mobile switcher 125 to the calling mobile switcher 120 through the communication network.

In step 627, the originating mobile exchange 120 transmits the voice channel establishment request to the terminating mobile exchange 125 through the communication network.

The destination mobile exchange 125 transmits an address complete message (ACM) corresponding to the voice channel establishment request received from the originating mobile exchange 120 to the originating mobile exchange 120 through the communication network in step 631, and through step 633. The call establishment and alerting message is transmitted to the called terminal 610. In addition, the called mobile switching center 125 transmits a voice channel setting request for transmission of the sound source data file to the additional service providing apparatus 152 in step 635.

In step 637, the additional service providing apparatus 152 responds to the voice channel setting request received through step 635 (e.g., an address complete message (ACM) and an answer message (ANM)). ) May be used, and a CON message may be used to simplify the message) to the destination mobile switching center 125 through the communication network.

In step 639, the additional service providing apparatus 152 transmits a sound source data file designated by the called party to the caller terminal so that a substitute sound corresponding to the sound source data file is output instead of a ring-back tone. When the mobile switch 125 receives the incoming connection signal from the called terminal 610 in step 641, the mobile switch 125 transmits a release message (REL: Release Message) to the supplementary service providing apparatus 152 in step 643 to request the disconnection.

In addition, when the incoming mobile exchange 125 receives a Release Complete Message (RLC) from the supplementary service providing apparatus 152 through the communication network in step 645, the incoming mobile exchange 125 proceeds to step 647 and responds to the originating mobile exchange 120. Send a message (ANM).

As a result, the voice channel for transmitting the sound source data set between the calling terminal and the additional service providing apparatus 152 is released, and a call path is formed between the calling terminal and the called party terminal to make a call (step 649).

Referring to FIG. 7, in step 710, the additional service providing apparatus 152 and the additional service control server 154 check a connection state between each system and a target system service operation state.

Since the detailed description associated with the step 710 is the same as the description of the step 310 of FIG. 3, duplicate description thereof will be omitted.

In operation 720, the additional service providing apparatus 152 transmits a sound source data file transmission information request to the additional service control server 154 through a communication network. The additional service control server 154 determines a sound source code corresponding to the sound source data file transmission information request received from the additional service providing apparatus 152 in step 730, and proceeds to step 740 to transmit to the caller's user terminal 110. Transmission information of the sound source data file to be transmitted is transmitted to the additional service providing apparatus 152 through a communication network.

Operation 720 to step 740 will be described in detail as follows.

The additional service providing device 152 receives a call from a switching system (that is, the intelligent network switch 130, the originating mobile switch 120, the incoming mobile switch 125, and a gateway switch (PGS: PCS Gateway System, etc.)). To determine a suitable supplementary service control server 154 using key information, such as key information (for example, calling number, called number, terminal location information (based on a base station unit), CDR-ID (Call Detailed Record-ID) (that is, Call resource ID of the supplementary service providing apparatus 152) to the supplementary service control server 154. The supplementary service control server 154 performs a service mode and a service subject in a manner similar to that of the supplementary service providing apparatus 152. FIG. After determining the number (refer to the description of FIG. 1), a service logic (ie, sound source code determination logic) corresponding to the corresponding service mode is performed to determine a sound source code to be transmitted to the user terminal 110.

In addition, the sound source data file transmission information transmitted to the additional service providing apparatus 152 through step 740 may include a sound source code, a repetition number of transmission of the sound source file, a performed service logic ID, a call ID (ie, additional service). Call resource ID) and CDR-ID (Call Detailed Record-ID) _ in the control server 154 may be included.

 The number of repetitive transmissions of the sound source file means the number of times that the sound source file is repeatedly transmitted when the subscriber does not respond even after the sound source data file has been transmitted in the additional service providing apparatus 152 and thus continuous transmission is required.

After the repeated transmission of the sound source file is completed, the additional service providing apparatus 152 requests the resource release to the switching system (ISUP-REL).

 Even if the service logic IDs performed are different in the same service mode, when different service logics are executed internally, different service IDs are allocated and transmitted.

 The CDR-ID 'is retransmitted without modification in operation 720 and used by the supplementary service providing apparatus 152 to check the correlation of the message.

 The call ID 'Call ID' is a call resource ID managed by the additional service control server 154 and is transmitted to receive a sound source transmission result. That is, if there is a call ID parameter, the additional service providing apparatus 152 transmits a confirmation message for the ongoing call after the call ends to the additional service control server 154, and does not transmit a confirmation message if there is no call ID parameter. The transmission of is determined by the service logic defined in the service mode. As an abnormal case, when the sound source data file transmission information request is transmitted in step 720, but if there is no response (Time-out) or an error response is received, the additional service providing apparatus 152 may transmit the basic sound source data to ensure the continuity of the service. The file is sent to the user terminal 110.

Referring to FIG. 7 again, in step 750, the additional service providing apparatus 152 transmits the sound source data file corresponding to the sound source data file transmission information received in step 740 to the user terminal 110 through the communication network.

Transmit to device 152.

That is, the additional service control server 154 transmits the sound source data file transmission information to the additional service providing apparatus 152, and then adds a confirmation request for the ongoing call to determine the validity of the current call after a predetermined time elapses. In this case, the progress call confirmation request may include a CDR-ID, a call number, and a call ID '.

 The calling number is auxiliary information for finding a call that matches the requested call, and the requested call can be found using the call resource ID of the call resource ID of the additional service providing apparatus 152 and the call service ID of the additional service control server 154. have.

In operation 790, the additional service providing apparatus 152 may determine whether the corresponding call proceeds or stops, and transmits response information (that is, an advanced call confirmation response) to the additional service control server 154 through the communication network.

Through this, the additional service control server 154 periodically checks the progress of the call by sending a confirmation request for the ongoing call to the ongoing call to perform call resource management of the additional service control server 154 according to the message loss. Will be.

After the transmission of the sound source data file is completed in step 750, the additional service providing device 152 proceeds to step 780 and transmits service performance report information to the additional service control server 154 through the communication network. The service performance report information transmitted to the service control server 154 may include a calling number, a called number, a starting time, an ending time, a call ID, a sound source code, and the like.

 Caller ID and Caller ID are supplementary information for checking the correspondence of call resources, start time and end time are data for calculating actual sound transmission time, and call ID is service request step (ie, step 720 to step 760). This data is for correlation with).

 The sound source code is a sound source code corresponding to the sound source data file transmitted from the actual supplementary service providing apparatus 152, and the supplementary service control server 154 may check whether the sound source data file has been normally transmitted.

If there is a mismatch between the sound source code transmitted from the additional service control server 154 through the step 740 and the sound source code transmitted from the additional service providing device through the step 760, it may be separately stored in the statistical data of the system and used when operating the system. .

The additional service control server 154 performs additional service logic according to the service mode by using the service performance report information received from the additional service providing apparatus 152, and proceeds to step 770 to return a response to the service performance report information to the communication network. Through the additional service providing device 152 through.

In this case, the additional service control server 154 generates a Call Detailed Record (CDR) if necessary and transmits it to the billing processing system 160. The generated CDR extracts information necessary for a service business such as service statistics in addition to the billing performance. The present invention is not limited to the above embodiments, and many variations are possible by those of ordinary skill in the art within the spirit of the present invention.
