Description

Method and system for setting a personal ring back tone using a ring back tone of a party in real time}

The present invention uses the complex frequency code signal of the calling terminal in real time while the subscriber of the calling terminal managed by the exchange in the communication network listens to the ringback tone replacing tone set by the called terminal subscriber in real time. The present invention relates to a ringback tone replacement sound service providing method and system configured to set its own ringback tone replacement sound.

In general, a ring back tone is a ring tone sent from a switch to a subscriber of a calling terminal to inform a subscriber of a calling terminal that a calling signal is being transmitted to a subscriber of a called terminal in a general switched telephone network (PSTN) or a mobile communication network. . Recently, various ring back tone services have been developed and used to replace ringback tones using the existing simple tones. For example, user-selectable two-ring, coloring, and filling services are exploding in popularity as the ITU-T recommendation replaces the uniformly provided ringback tone. The ring back tone replacement sound service will be described in detail as follows.

1 is a diagram illustrating a ringback tone replacement sound service process in a conventional communication network.

Referring to FIG. 1, a conventional communication network includes a mobile switching center (MSC: 103, 104), a service switching point (SSP) 105, which manages at least one mobile communication terminal 101, 102. No.7 signaling network (SS7 Network) 107, which combines the exchanges 103 and 104, the service exchange 105, and an Intelligent Peripheral (109) server (hereinafter referred to as an IP server), and an IP server 109 And a sound source providing device (106) coupled to provide a ringback tone replacement sound. The sound source providing device 106 includes a sound source providing control server 108.

In addition, the conventional communication network includes a Service Control Point (SCP) server (hereinafter referred to as SCP server) coupled to the IP server 109, and an authentication and billing network (WISE or CS / BS (Customer Care & Service). Biling System) An authentication and billing server (WISE (CS); 115) coupled to the SCP server 111 via a network; 113, and an SCP server 111 coupled via a short message service network (SMSC Network 117). Short message service center (SMSC) 119.

In addition, a conventional communication network is coupled to a content provider (MCP) server (hereinafter referred to as an MCP server) coupled with an IP server 109 and an SCP server 111, and an MCP server 121. An external answering system (ARS) 127 is included. The MCP server 121 is coupled to the Internet user terminal 125 through the Internet 123. In addition, the ARS 127 is coupled to the mobile communication terminal 131 and the wired terminal 133 through a mobile communication network (MSC) or a public switched telephone network (PSTN) 129.

The ring back tone replacement tone service in the conventional communication network is, for example, when the mobile communication terminal 101 serving as the calling terminal attempts to connect to the mobile communication terminal 102 serving as the called terminal, and the calling terminal 101 is connected. ) Is made to receive the ringback tone replacement sound from the sound source providing device 106 coupled to the destination side exchange 104 via the IP server 109. The conventional ringback tone replacement sound service will be described in detail below.

2 is a signal flow diagram illustrating a signal flow of a ringback tone replacement sound service in a conventional mobile communication network.

Referring to FIG. 2, when the calling terminal subscribes to the ringback tone replacement service and requests a call connection to the called terminal managed by the called side exchange (MSC), the calling side exchange (MSC) is sent to the home location register (HLR). The caller requests location information (Location Request) (step 201). The HLR requests routing information from the originating exchange to the destination exchange in response to the request for the called location information from the originating exchange (step 203). The destination exchange sends the routing information (TLDN: Temporary Local Directory Number) to the HLR in response to the routing information request signal received from the HLR (step 205). The HLR then sends the called location information to the calling exchange using the received routing information (step 207).

The originating exchange requests the ISN (ISDN User Part) call connection to the called exchange based on the routing information (step 209). The called exchange reads the ringback tone replacement tone service setting information stored in the storage device in advance according to the ISUP call connection request signal transmitted from the calling exchange, and then a user corresponding to the called terminal subscribes to the ringback tone substitute tone service. In this case, the ISUP call connection request signal is transmitted to the sound source control device using the routing information corresponding to the previously stored sound source control device (step 211). At this time, the ISUP call connection request signal includes a called terminal identifier and a calling terminal identifier. As a result of this process, a call path is formed between the source exchange, the destination exchange and the sound source providing device.

The sound source providing apparatus requests a sound source code to the sound source providing control server based on the received called terminal identifier and the calling terminal identifier (step 213). In response to the sound source code request signal, the sound source providing control server searches for a sound source code stored in connection with the called terminal identifier or the calling terminal identifier and transmits the found sound source code to the sound source providing apparatus (step 215). Thereafter, the sound source providing apparatus transmits a ringback tone substitute sound corresponding to the sound source code received from the sound source providing control server to the calling terminal through the formed call path (step 217). If the called exchange recognizes that the called terminal responds while the ringback tone replacement tone is being transmitted to the calling terminal, it requests the ISUP call release from the sound source providing apparatus (step 219). The sound source providing apparatus releases the call path set as the calling terminal after receiving the ISUP call release request signal from the called side exchange. Thereafter, the called terminal performs a normal call using the call path set in the calling terminal (step 221).

The called terminal subscriber can use the above-described ring back tone substitute tone service to give the calling terminal subscriber a ring back tone substitute tone that replaces the existing uniform ring back tone selected by the calling terminal subscriber. The reason why such ringback tone replacement service is commercially successful may be that it satisfies the desire of modern people to express personality to some extent.

However, the conventional ringback tone replacement tone service has a limitation that a subscriber who wants to change the ringback tone replacement tone should be subscribed to the same network operator having the corresponding ringback tone replacement tone. In addition, in order to change the ringback tone replacement sound, it is necessary to access the homepage, the wireless Internet, or the ARS of a network operator providing the ringback tone replacement sound service, and the ringback tone replacement sound can be changed only by entering the subscriber's telephone number.

That is, the conventional ringback tone replacement sound service has a disadvantage in that it cannot set the ringback tone replacement sound in real time during a wired or wireless telephone call and its procedure is also cumbersome. That is, the subscriber who subscribes to the ringback tone replacement sound service of the specific service provider cannot listen to the ringback tone replacement sound of the called party and change it to his ringback tone replacement sound in real time. For example, the calling terminal subscriber may not know the sound source information such as the singer or the title of the ringback tone replacement sound or change it later even after listening to the ringback tone replacement sound of the other party who wants to use it as his ringback tone replacement sound. The ringback tone replacement was not changed because it was forgotten, did not know the telephone number or internet address of the content provider providing the ringback tone replacement, or because the procedure for changing the ringback tone replacement was cumbersome and complicated.

An object of the present invention is a ringback tone being listened in real time using a shortcut key or a complex frequency code signal of a calling terminal while a subscriber of an calling terminal coupled to an exchange in a communication network listens to a ringback tone replacement tone set by a called terminal subscriber. It is proposed a method and system that can instantly set a substitute sound as its ringback tone substitute sound.

Another object of the present invention is to provide a method for subscribing to a ringback tone replacement service or a telephone number, an Internet address, or a singer or sound source title of a content provider that provides a ringback tone replacement sound service or a desired ringback tone replacement sound. Even if you do not know the information, it is to propose a method and system that can easily set the ringback tone replacement sound of the other party as their ringback tone replacement sound.

It is still another object of the present invention to propose a method and system for easily subscribing to a ringback tone substitute sound service and setting a sound source for a ringback tone substitute sound by using a shortcut key while transmitting a mobile phone anytime and anywhere.

At this time, the IP server collects the information for the ringback tone replacement tone service of the called party and obtains the necessary information from the SSP server capable of recognizing the DTMF signal input to the originating exchange as the intelligent network service call (step 405). Thereafter, the IP server transmits the collected information for the ringback tone replacement tone service of the called party to the ringback tone replacement tone service providing apparatus according to the present invention according to the service information set according to the specific DTMF signal (step 407). Here, the ring back tone substitute sound service providing apparatus includes a gateway system (G / W). And the collected information includes at least customer information such as an originating terminal identifier corresponding to the calling terminal and a called terminal identifier corresponding to the called terminal, a network operator code related to the called party's ringback tone replacement tone, and a CP server related to the ringback tone replacement tone of the called party. Sound source information such as a code and a subscriber code / serial number related to the ringback tone substitute sound of the called party.

The G / W, which has received the collection information from the IP server, transmits a sound source setting request signal including at least the calling terminal identifier in the collection information and the sound source information to the CP server (step 409). Receiving the sound source setting request signal from the G / W, the CP server extracts the sound source code for the caller's ringback tone replacement sound from the sound source code for the ringback tone replacement sound of the called party using the ringback tone replacement tone code conversion table (step 411). The ringback tone substitute tone code conversion table is used when the ringback tone substitute tone service provider subscribed to by the caller and the called party is different. Therefore, if the ringback tone substitute tone service provider subscribed to by the caller and the called party is the same, step 411 may be omitted. On the other hand, when the calling terminal subscriber is the first subscriber to the ringback tone substitute tone service, the present invention sets up the ringback tone substitute tone service through a predetermined subscription procedure through the service notification process described later (see FIG. 8A). .

Thereafter, the CP server requests the SCP server to set the sound source to set the ringback tone substitute to be substantially the same as the ringback tone substitute of the called party as the ringback tone substitute of the caller (step 413). The SCP server sets a new or changed ringback tone substitute tone corresponding to the originating terminal identifier (step 415). Meanwhile, the apparatus for providing a service transmits data on a call detail record (CDR) of a ringback tone replacement tone setting service to an Internet Detail Recording System (IDR) server for billing settlement.

5 is a signal flow diagram illustrating a signal processing procedure for a ringback tone substitute tone service according to an exemplary embodiment of the present invention. In the present embodiment, in order to facilitate the distinction between the conventional ringback tone replacement tone service and the ringback tone replacement tone service of the present invention, the conventional ringback tone substitute tone is called a ring back tone.

Referring to Fig. 5, when a calling terminal subscriber requests a call connection to a called terminal managed by a called side exchange (MSC) by pressing a dial key of the calling terminal (step 501), the calling side exchange (MSC) is a home location register. (Location Request) is requested to (HLR) (step 503). The HLR requests routing information to the destination exchange for the called location information request from the originating exchange (step 505). The called side exchange managing the called terminal sends routing information (TLDN) to the HLR in response to the routing information request signal from the HLR (step 507). The HLR then sends the called location information to the calling exchange using the received routing information (step 509).

The originating exchange requests the ISDN user part (ISP) call connection to the destination exchange based on the routing information from the HLR (step 511). When the called terminal reads out the ringback tone replacement tone service setting information previously stored in the storage device based on the ISUP call connection request signal from the calling exchange, and the subscriber terminal subscriber subscribes to the ringback tone substitute tone service, The ISUP call connection request signal is transmitted to the sound source control device by using the routing information on the sound source control device (step 513). Here, the ISUP call connection request signal includes the called terminal identifier and the calling terminal identifier. The sound source control device is also coupled to the IP server.

As a result of performing the above process, a call path is formed between the calling exchange, the called exchange, and the sound source providing device. Thereafter, the sound source providing apparatus requests a sound source code to the sound source providing control server coupled to the SCP server based on the called terminal identifier and the calling terminal identifier (step 515). In response to the sound source code request signal, the sound source providing control server searches for a sound source code stored in connection with the called terminal identifier or the calling terminal identifier and transmits the found sound source code to the sound source providing apparatus through the IP server (step 517). Thereafter, the sound source providing apparatus transmits a ring back tone corresponding to the sound source code received from the sound source providing control server through the SCP server to the calling terminal through the formed call path (step 519).

Then, while the calling terminal subscriber listens to the ring back tone set by the called terminal subscriber, it is requested to press the dial key of the calling terminal to set the ringback tone currently being listened to as his ringback tone replacement tone (step 521). In response to the request of the calling terminal subscriber, the IP server detects and recognizes a specific DTMF signal by the calling terminal in the state of receiving the ring back tone of the calling terminal. In practice, DTMF signals are recognized by the SSP server and forwarded to the IP server.

Specific DTMF signals mentioned above include "#", "*", "# + *", "# 016", and the like. In addition, the IP server receives the collected information from the SSP server collected to service the ring back tone set by the current terminal subscriber. The collected information includes at least customer information such as an originating terminal identifier (originating Mobile Identification Number) corresponding to the originating terminal and a terminating terminal identifier corresponding to the called terminal, the ID of the content provider for the called party's ring back tone and the ring back tone. Sound source information such as serial number or sound source code.

Upon detecting the specific DTMF signal, the IP server transmits the collection information to the ringback tone replacement sound service providing apparatus according to the present invention according to the service information set corresponding to the DTMF signal (step 523). In this case, the collection information transmitted to the service providing apparatus includes at least the calling terminal identifier and the sound source information. The service providing apparatus transmits a sound source setting request signal including the calling terminal identifier and the sound source information to the CP server (step 525).

The CP server uses the sound source code for the ring back tone in the sound source information (hereinafter referred to as 'first sound code') and the ring back tone substitute tone code conversion table to use as a sound source code for the ring back tone substitute sound for the calling terminal ( Hereinafter referred to as "second sound source code" (step 527). Here, the sound source code change comparison table refers to a table arranged for different sound source codes set for the same sound source when the ring back tone service provider and the ringback tone substitute sound service provider are different. On the other hand, in the present invention, when the ring back tone service provider and the ringback tone substitute sound service provider are the same, the first sound source code may be used as the second sound source code as it is.

Thereafter, the CP server sends a sound source setting request signal including at least the calling terminal identifier and the second sound source code to the SCP server (step 529). The SCP server sets the second sound source code as a ringback tone replacement sound service for the calling terminal according to the sound source setting request signal of the CP server.

6 is a signal flow diagram illustrating a signal processing procedure for a ringback tone replacement tone service according to a modification of the preferred embodiment of the present invention. In the following detailed description with reference to FIG. 6, detailed descriptions of the same parts of the first half of FIG. 5 will be omitted.

6, while the calling terminal subscriber listens to the ring back tone set by the called terminal subscriber (step 619), the calling terminal subscriber sets the ring back tone of the called terminal subscriber to his ringback tone replacement tone. When the dial key is pressed, the IP server detects a specific composite frequency code (DTMF) signal sent from the originating terminal to the originating exchange (step 621). In fact, the IP server receives a specific DTMF signal recognized by the SSP server. At this time, the SSP server collects information for servicing the ring back tone, and provides the collected information to the IP server. The collected information includes customer information and sound source information such as an originating terminal identifier, a called terminal identifier, an ID of a content provider providing a ring back tone, a serial number of the ring back tone, and the like.

The IP server detecting the specific DTMF signal transmits the collection information obtained from the SSP server to the service providing apparatus according to the ringback tone replacement tone service information set in the specific DTMF signal (step 623). The service providing apparatus processes the collection information received from the IP server. The processed collection information is stored in a database. Thereafter, the service providing apparatus that has received the collected information transmits a sound source basic information request signal including sound source information to an MCP (Master Contents Provider) server in order to obtain basic information about the ring back tone (step 625). At this time, the service providing device extracts the sound source information stored in the database in a first in, first out (FIFO) method and transmits it to the MCP server. The MCP retrieves the sound source title and artist name corresponding to the sound source code from the storage device based on the sound source information, reads the basic sound source basic information (step 627), and transmits it to the service providing device (step 629).

The service providing apparatus having obtained the sound source basic information transmits a sound source setting request signal including an originating terminal identifier and sound source basic information to the CP server (step 631). The CP server extracts a sound source code (second sound source code) to be used as a ringback tone replacement sound of the calling terminal subscriber based on the ringback tone replacement tone code conversion table based on the sound source basic information (step 633). Thereafter, the CP server sends a sound source setting request signal including the calling terminal identifier and the second sound source code to the SCP server (step 635).

7A is a flowchart schematically illustrating a ringback tone replacement sound service process according to whether a service is registered according to an exemplary embodiment of the present invention.

4 and 7A, the ringback tone replacement sound providing service according to the present invention includes a registration process for a service non-registered customer.

Recognize as an intelligent network service request and perform the service accordingly. When the CP server receives the sound source setting request signal for the calling terminal subscriber from the service providing system, the CP server determines whether the calling terminal subscriber is a registered customer in the ringback tone replacement tone service. (Step 701). If it is determined that the customer is not a registered customer, the CP server requests WISE (CS) for new customer registration for the calling terminal subscriber (step 703). Thereafter, the apparatus for providing a service notifies the user of the ringback tone replacement tone service by using a short message, and provides the ringback tone replacement tone service after confirming the user's intention to subscribe. This process is described below.

7B is a flowchart schematically illustrating a process of notifying a ringback tone replacement tone service according to an exemplary embodiment of the present invention.

Referring to FIG. 7B, after appropriately performing a service request of an originating terminal subscriber who wants to set a ringback tone of a called terminal subscriber as his / her ringback tone replacement tone, the service providing apparatus transmits a ringback tone replacement tone setting service history to a calling terminal. Notify subscribers. Specifically, the service providing apparatus first checks whether the ringback tone replacement tone setting service history is set to notify the calling terminal (step 705). If it is confirmed that the service notification is set, the service providing device requests the SMSC to send a text message to the calling terminal (step 707). Here, the text message simply includes a message for notifying the setting or change of the ringback tone substitute sound. In addition, the text message may include a callback number or URL address for a new subscription of the calling terminal subscriber with a message indicating that the ringback tone replacement tone setting request has been received. In addition, the text message includes a callback number or URL address for allowing the calling terminal subscriber to access the CP ARS server and using an additional service together with a message for notifying the ringback tone replacement tone setting by the calling terminal subscriber. This process is described below.

8A is a flowchart schematically illustrating a process of joining and using an additional service of a ringback tone substitute sound service according to an exemplary embodiment of the present invention.

Referring to FIG. 8A, first, a calling terminal subscriber receives a short message received at a calling terminal (step 710). At this time, the calling terminal subscriber checks the ringback tone replacement tone setting service history requested by the user through a short message. The calling terminal subscriber then accesses the CP's ARS server using a Call Back phone number or URL address (step 712).

At this time, if the calling terminal subscriber is not a ringback tone replacement tone service registered customer, the calling terminal subscriber selects a subscription (step 714). Thereafter, the calling terminal subscriber proceeds with the membership registration procedure according to the guidance of the ARS server of the CP (step 716). The calling terminal subscriber uses the supplementary service of the ring back tone replacement tone service according to the present invention (step 718).

As such, the service providing apparatus according to the present invention notifies the calling terminal subscriber of new subscription contents such as the terms and conditions or sound source setting contents using a short message of the SMSC. In addition, the present invention allows the calling terminal subscriber to access the ARS server of the CP through the callback phone number or URL address included in the short message. By this process, the calling terminal subscriber can register, listen to the ringback tone replacement tone set by the ARS server, or use other additional services. In addition, the calling terminal subscriber accessing the ARS server may inquire additional service or other matters through the customer center. The additional service will be described below.

8B is a view for explaining an example of a process of using an additional service of a ringback tone substitute tone service according to an exemplary embodiment of the present invention.

Send to the calling terminal. For example, ARS sends out the phrase, "This is a catching service provided by K. Press 0 to inquire about joining the service, or press 2 to use additional services such as listening to music."

Then, if the user selects 0, the calling terminal is connected to, for example, the customer center of K company. On the other hand, if the user selects No. 2, the ARS sends the announcement about the additional service to the calling terminal. For example, ARS is an announcement about an add-on service that says, "1 to listen to the sound source, 2 to gift to a friend, 3 to set the time zone, 4 to set it by sender, and 4 to set an anniversary. Press 5 to make a comment.

When the user guided by the additional service selects a specific number, the ARS sends the announcement about the additional service to the calling terminal and performs the service according to the user's instruction. For example, when the user selects No. 1 of the supplementary service, the ARS immediately transmits the ringback tone replacement sound source set / modified by the user to the user's calling terminal. If the user selects No. 2 of the supplementary service, the ARS sends a message, for example, "Please press the mobile phone number of the person you want to present and then press the well sperm" and follow the user's input information. Perform. If the user selects No. 3 of the supplementary service, the ARS sends a message saying, "To set the selected sound source as the time zone, enter the start time and the end time. Perform the service according to the user's input information. If the user selects No. 4 of the supplementary service, the ARS sends a message to the user's input information, for example, "To set the selected sound source by calling party number, send the message" Press the dialing number and press the well sperm. " Perform the corresponding service accordingly. If the user selects No. 5 of the additional service, the ARS sends the anniversary setting announcement and then performs the service according to the user's input information.

As such, the ringback tone replacement tone setting method according to the present invention may further include informing the calling terminal subscriber of ringback tone replacement tone setting information as described above. For example, a short message service may be used to notify ringback tone replacement tone setting / change information, or a short message service and callback number in a short message may be used to transmit ringback tone replacement tone setting / change information. Use of additional supplementary services may be induced by the calling terminal subscriber. In addition to the short message service, a wireless Internet service through a WAP / Me push server and a WAP / Me server may be used. Through such a service, the ringback tone substitute sound service according to the present invention enables not only registered subscribers but also registered customers to easily subscribe to the ringback tone substitute tone service and set the ringback tone substitute tone in real time.

As described above, according to the ringback tone replacement sound setting method according to the present invention, a customer who subscribes to the first ringback tone replacement sound service immediately listens to the ringback tone replacement sound of the other party whenever an online telephone call is attempted, and then replaces his or her ringback tone replacement sound. It is possible to set. Second, in the case of a customer who does not subscribe to the ringback tone replacement sound service, it is possible to subscribe to the ringback tone replacement sound service immediately in real time after listening to the ringback tone replacement sound of the other party when attempting to dial online. Third, in the case of a mobile communication service provider, it is possible to induce new subscribers and create additional profits by increasing customer. Fourth, in the case of the mobile communication service provider and the CP, the customer may frequently change the sound source for the pre-produced sound source, thereby increasing the additional revenue by changing and reusing the sound source. Fifth, it is possible to easily induce new subscriptions for customers who do not subscribe because they do not know the method and procedure of ringback tone replacement.

15 is a flowchart showing a ringback tone replacement sound service process according to this preferred embodiment of the present invention. This embodiment describes a ringback tone replacement sound service process by interworking a network including at least two service providing systems.

Referring to FIG. 15, when the calling terminal subscriber requests to set / change the ring back tone of the called party to its ringback tone substitute tone using a dial key, the first IP server coupled to the called exchange exchanges the calling terminal subscriber. The specific DTMF signal of the specific shortcut key pressed is detected (step 1501). The first IP server that detects a specific DTMF signal during the ring back tone service recognizes it as a ringback tone replacement tone service request and provides the first service with customer information and sound source information in association with the first service providing G / W system of the present invention. Transmit to G / W system (step 1503). Here, the customer information includes the calling terminal identifier and the called terminal identifier. The sound source information includes a sound source code including a CP ID and a sound source serial number.

The first service providing G / W system receiving the information on the ringback tone replacement tone service request transmits sound source setting request information for the calling terminal subscriber to the second service providing G / W system in the mobile communication provider of the calling terminal subscriber. (Step 1505). The second service providing G / W system requests a sound source setting according to whether a customer is registered to the second MCP server coupled with the second service providing G / W system (step 1507).

The MCP server determines whether the calling terminal subscriber is a registered customer based on the received customer information (step 1509). As a result, if the calling terminal subscriber is not an existing subscription customer, the MCP server requests a new customer registration from the WISE (CS) (step 1511). The MCP server requests the SCP server to set the sound source based on the sound source information (step 1513). If it is determined in step 1509 that the calling terminal subscriber is a registered customer, the MCP server requests a sound source change directly from the SCP server (step 1515). In this case, the MCP server generates or extracts a sound source code suitable for the ringback tone substitute sound of the caller using a sound source code comparison table or mapping table received from a plurality of CP servers. Thereafter, the SCP server sets the called party's ring back tone to the caller's ringback tone replacement tone at the request of the MCP server (step 1517). Through this process, the calling terminal subscriber can conveniently and conveniently receive the ringback tone replacement sound service according to the present invention regardless of the communication service provider to which the called terminal subscriber subscribes.

16A and 16B are flowcharts illustrating a ringback tone replacement sound service process according to a modification of this preferred embodiment of the present invention. 17 is a diagram schematically illustrating a ringback tone replacement sound service process of FIGS. 16A and 16B.

Referring to FIGS. 16A, 16B, and 17, when the calling terminal subscriber requests to set / change the ring back tone of the called party to his / her ringback tone substitute tone using a shortcut key, the first IP coupled to the called side exchange may be connected. The server detects a specific DTMF signal of a specific hot key pressed by the calling terminal subscriber (step 1601). The first IP server that detects a specific DTMF signal during the ring back tone service to the calling terminal subscriber recognizes it as a request for ringback tone replacement tone service, and interoperates with the first service providing G / W system of the present invention to provide customer information and sound source. The information is transmitted to the first service providing G / W system (step 1603). Here, the customer information includes the calling terminal identifier and the called terminal identifier. In addition, the sound source information includes a sound source code including a CP ID (ID) and a sound source serial number.

The first service providing G / W system receiving the ringback tone replacement tone service request transmits the sound source information to the first MCP server in order to know the sound source detailed information set by the called terminal subscriber (step 1605). The first MCP server is coupled to the first IP server and the first service providing G / W system. Thereafter, the first MCP server retrieves the sound source detailed information of the called party's call connection sound from the storage device, reads the sound source detailed information, and transmits the same to the first service providing G / W system (step 1607). Here, the detailed information of the sound source may include location information of the CP server that provides the call connection tone of the called party.

The first service providing G / W system that prepares the necessary information for the ringback tone replacement tone setting request of the calling terminal subscriber is transmitted to the second service providing G / W system in the mobile communication service provider subscribed to with the transmission of the prepared information. A sound source setting for the ringback tone substitute sound is requested for the calling terminal subscriber (step 1609). The second service providing G / W system requests whether the calling terminal subscriber is subscribed to the second MCP server and basic sound source information based on the information received from the first service providing G / W system. At this time, the second service providing G / W system transmits the sound source information on the calling terminal identifier and the called party's ring back tone to the second MCP server (step 1611).

The second MCP server reads the artist name and title to be used for selecting a ringback tone substitute sound source of the calling terminal subscriber from the storage device according to a request of the second service providing G / W system, and then uses the second service providing G / W Send to system (step 1613). In this case, the second MCP server may further transmit the location information of the specific CP server providing the call connection tone of the called party.

The second service providing G / W system transmits to the CP server basic information about the sound source including customer information such as a calling terminal identifier and a CP ID and a singer name and title received from the second MCP (step 1615). This is to obtain a sound source code to be used for ring back tone replacement tone service requested by the calling terminal subscriber. Receiving the basic information of the sound source, the CP server selects the sound source code to be used as the ringback tone replacement tone of the calling terminal subscriber using the ringback tone substitute tone code conversion table and transmits it to the second service providing G / W system. (Step 1617).

In order to perform the ringback tone replacement tone service according to the request of the calling terminal subscriber, the second service providing G / W system requests a sound source setting according to whether a customer is registered in the second MCP server (step 1619). The second MCP server determines whether the calling terminal subscriber is a registered customer based on the received customer information (step 1621). As a result, if the calling terminal subscriber is not a registered customer, the second MCP server requests a new customer registration from the WISE (CS) (step 1623). The second MCP server requests the SCP server to set the sound source (step 1625). On the other hand, if it is determined in step 1621 that the calling terminal subscriber is a registered customer, the second MCP server requests a change of sound source immediately from the SCP server (step 1627). Thereafter, the SCP server sets the sound source code received from the CP server as a ringback tone substitute sound of the calling terminal subscriber at the request of the second MCP server.

Thereafter, the second service providing G / W system optionally notifies the calling terminal of the new subscription contents or the sound source setting details using the SMSC short message service (step 1629). The second service providing G / W system optionally transmits service description data for the ringback tone replacement tone service to the IDR server (step 1631). At this time, the calling terminal subscriber may access the ARS system through the callback telephone number or URL address included in the short message to use an additional service such as listening to a set sound source or to use the guidance of the customer center (step 1633). Meanwhile, in the present invention, an additional service providing method using a WAP / Me push server and a WAP / Me server may be selectively adopted in addition to an additional service providing method using an SMSC and an ARS system.

As a result of performing the above process, the calling terminal subscriber can conveniently and conveniently provide a ringback tone replacement sound service, which can be called a catch ring service according to the present invention, regardless of the network operator to which the called terminal subscriber subscribes. have.
