PURPOSE: A method for confirming a sound source in a subscriber-based ringback tone service is provided to confirm the sound source of a subscriber or other subscriber without the occupation of an unnecessary trunk resource and a telephone call. CONSTITUTION: If the random first subscriber mobile terminal connects to an ARS(Automatic Response System)(55) through an origination MSC(Mobile Switching Center)(31)(S401), the ARS(55) performs an inquiry according to a predetermined scenario and the first subscriber answers to the inquiry through the key input of the first subscriber mobile terminal(S402). The ARS(55) acquires telephone number information of the second subscriber selectively inputted from the first subscriber mobile terminal and a telephone number of the first subscriber mobile terminal(S403). The ARS(55) inquires code information corresponding to telephone number information of the second subscriber to an IP server(70) on the basis of telephone number information of the second subscriber, and requests a corresponding sound source code(S404). The IP server(70) searches code information corresponding to the telephone number of the second subscribe from a database according to the request, and provides searched code information to the ARS(55)(S405). The ARS(55) searches a sound source corresponding to code information from the database, and transmits the searched sound source to the first subscriber mobile terminal through the origination MSC(31) for confirming the sound source of the second subscriber(S406). The ARS(55) judges whether the change of the sound source is requested from the first subscriber mobile terminal on the basis of the inquiry/response according the scenario(S407,S408). If the change of the sound source is requested, the ARS(55) requests the change of the sound source code to the IP server(70) on the basis of the first subscriber telephone number and the second subscriber telephone number(S409). The IP server(70) changes code information corresponding to the first subscriber telephone number to code information corresponding to the second subscriber telephone number, and stores changed code information(S410).

Description

Sound source confirmation method in subscriber-based ringback tone service {Method for confirming RBT Source in Subscriber-based Ring-Back-Tone Service}

The present invention relates to a method for identifying a sound source in a subscriber-based ringback tone service, and more particularly, to improve a conventional uniform ringback tone method by providing a specific sound desired by a called subscriber as a ring back tone. In implementing a subscriber-based ringback tone service, the present invention relates to a method for identifying a sound source of one or another as the specific sound.

In general, when a caller attempts to make a phone call in an existing mobile communication network, the receiver of the called subscriber adopts a method of giving a uniform ringback tone to the caller. However, such a conventional ringback tone method uses a uniformly identical tone. Since the caller cannot determine whether there is a misconnection until the answer of the called party, there is also a problem that can not provide a variety of ringback tone replacement service to meet the characteristics of the user.

On the other hand, in recent years, a method of listening to various advertisement sounds instead of the uniform ringback tone has been proposed, but this also gives a caller a specific advertisement sound selected by a network operator without a subscriber's option and then a predetermined time. Since it is a way to make a free call for a while, the caller cannot determine whether there is a misconnection until the answer of the called party, and furthermore, there is a problem in that it cannot provide various ringback tone services that match the characteristics of the user.

In order to solve such a problem, a subscriber-based ringback tone service method has been proposed by the applicant of the present invention to provide a caller instead of an existing ringback tone to a specific sound registered or selected by a called subscriber. The description is as follows.

1 is a flowchart of a subscriber-based ringback tone service method previously proposed by the applicant of the present invention. Refer to National Application No. 10-2002-0010006 (Application Date: 2002.02.25).

First, when an arbitrary caller calls a service subscriber (hereinafter referred to as a called subscriber) according to the proposal and requests a call connection, the calling exchange 31 requests the called location information from the home location register 10 ( Location Request) (S101).

The home location register 10 requests routing information from the destination exchange 32 according to the request (Routing Request) (S102), and accordingly, the destination exchange 32 sends routing information to the home location register 10. (Ie, provide a TLDN: Temporary Local Directory Number) and respond (S103).

The home location register 10 transmits the routing information to the originating exchange 31 and responds to the step S101 (S104). Accordingly, the originating exchange 31 transfers the destination exchange based on the routing information. 32) requests a trunk (hereinafter referred to as ISUP) call connection to form a mutual call path (S105).

Then, the destination exchange 32 receives a call from the home location register 10 when registering a location, and the called party receives the present invention based on service setting information for the present proposal and the routing information to the sound source providing device 50. If it is determined that the subscriber is a service and the service is activated, the ISUP call connection is made to the sound source providing apparatus 50 based on the routing information to form a trunk trunk path, and the caller ID and the outgoing telephone number are also provided. S106). As a result, the call exchanger 31, the call exchanger 32, and the sound source providing device 50 are in a state in which a call path is formed. For reference, the service setting information and the routing information are provided in a location registration response message provided from the home location register 10 to the destination exchange 32 when the location is registered.

The sound source providing device 50 queries the sound source providing control server 70 by requesting a sound source code based on the received incoming call number and the outgoing call number information (S107), and the sound source providing control server 70. Search for a designated sound source code in association with the provided incoming / outgoing telephone number according to the request, and transfers the found sound source code to the sound source providing device 50 in response to step S107 (S108), wherein the sound source providing device 50 transmits the sound source corresponding to the received sound source code from the pre-stored sound source to the caller through the formed communication path as a substitute sound for the ring back tone (S109).

Finally, the destination exchange 32, when the incoming subscriber receives a call while the replacement sound is being transmitted instead of the ringback tone as described above, requests the sound source providing device 50 to release the ISUP call, and the sound source providing device. 50 to release the call (S110). At the same time, a call is made between the caller and the called subscriber through the call path mutually formed with the calling exchange 31 (S111).

By the way, in the subscriber-based ringback tone service described above, in order to check what the sound source of the self or another person is, call the corresponding subscriber of the desired sound source and listen to the ringtone tone as the replacement sound of the ringback tone as in the step S109. There was only a way to listen to it.

Therefore, even when the user does not want to make a call and only wants to check the sound source, an unnecessary trunk resource is occupied from the network point of view, the trunk resource is wasted, and an unnecessary call is made from the subscriber point of view.

The present invention has been created to solve the above problems, the purpose of the subscriber-based ringback tone service in the subscriber-based ringback tone service, so that it is possible to identify what is the source of their own or others without occupying trunk resources and calls It is to provide a sound source confirmation method in the ringback tone service.

Register (HLR) 10; Switchboards (O_MSC / VLR, T_MSC / VLR) (31,32) that communicate with the home location register (HLR) 10 via a No.7 network (20) based on a Signaling Transfer Protocol (STP). ; A sound source providing device (Intelligent Peripheral: IP) 50 connected to the No. 7 network 20 and communicating with the exchanges 31 and 32 via a gateway (CGS) 40; A sound source providing control server (IP server) 70 for data communication with the sound source providing apparatus 50 via the Internet network 60; A subscriber database (80) connected to the home location register (10) via the internet network (60); A sound source providing device 50 connected to the Internet network 60 through a gateway 90; And a web server 100 communicating with the sound source providing control server 70.

The home location register 10 has all of the functions of the existing network components, and receives the first information on the presence or absence of ringback tone replacement and the second information for routing to the sound source providing device 50. A function which has a preset function as profile information for is newly added, and the information is set and stored as additional service subscription information of the called party profile.

The exchanges 31 and 32 have all functions as existing network components, and communicate with the home location register 10 when registering a destination subscriber to receive and store the predetermined first and second information. Receiving a sound source for replacing a ringback tone by communicating with the sound source providing apparatus 50 based on the stored first and second information when a call connection request of a called subscriber is received, and replacing the received sound source with the caller. It also has a negatively provided feature.

The sound source providing device 50 stores various sound sources and is connected to the exchanges 31 and 32 via the gateway 40 to communicate with the exchange sources 31 to provide the stored sound sources to the exchanges 31 and 32. Has characteristics.

The sound source providing control server 70 communicates with the sound source providing device 50 via the Internet network 60, so that the sound source providing device 50 is provided to the switchboards 31 and 32. The type is specified based on a combination of identification information of the called subscriber who is requested to make a call connection, identification information of the caller corresponding to the call connection, and / or call connection request time zone information (e.g. By age, gender, occupation, and / or calling time zone, respectively). For example, a code is assigned to various sound sources stored in the sound source providing apparatus 50, and when the called party joins or When changing the information, select the sender, sender group, calling time zone, etc., and specify the corresponding sound source, and have the information about this as a table and then based on the table information. The sound source and controls the sound source providing device 50 to be provided to the heat exchanger 32 side.

The web server 100 is connected to the sound source providing apparatus 50 or the sound source providing control server 70 via the Internet network 60, to add the sound source stored in the sound source providing apparatus 50 or In order to change the information (specific caller, caller group, call time zone, etc.) and the corresponding sound source code for the sound source specification of the sound source providing control server 70, which is provided by the subscriber in the web server 100 This can be done via a web page.

The operation of FIG. 2 will be described.

When a called subscriber who wants to use a specific sound transmission service applies to a service provider to which he / she belongs, it is registered in the service provider subscriber database 80 and registered in the service provider subscriber database 80 as a home location register 10 which is an element in the network. , The home location register 10 sets the corresponding service in its subscriber database, and service information when the location registration procedure occurs from the home location register 10 to the corresponding switching service (Serving switch) 31 or 32 that is currently moving. And routing data that can be set to a call source providing device (IP) 50, and the switch 32 sets the received service information and routing data in the corresponding subscriber service data. Therefore, when the calling subscriber requests a call setup from the called subscriber, the called exchange 32 detects that a specific sound source transmission service is set based on the set service information, and uses the routing data to transmit the call to the sound source providing apparatus 50. At the same time as the call connection, the called subscriber is informed that the incoming call is introduced (Paging). In this case, the sound source providing apparatus 50 interoperates with the sound source providing control server (IP Server) 70 and inquires about which sound source is set by the corresponding subscriber. The sound source providing control server 70 transfers a code for a particular sound source from the subscriber to the sound source providing apparatus 50. The sound source providing apparatus 50 transmits the sound source for the corresponding code in place of the existing ringback tone so that the caller can listen to the sound source until the called subscriber responds. When the called party receives the incoming call, the called exchange 32 disconnects the call route set by the sound source providing device 50 and connects the called party and the calling party to perform telephone communication.

3 is a basic configuration diagram of an apparatus for implementing a sound source identification method in a subscriber-based ringback tone service according to an embodiment of the present invention. Since the construction is based on the apparatus of FIG. It demonstrates by adding a code | symbol.

As shown in the figure, the switches 31 and 32 as constituent nodes of a mobile communication network; The sound source providing control server 70; And the same as the sound source providing apparatus 50 of Figure 2 is equipped with a variety of sound sources corresponding to the code information, and the subscriber mobile terminal (not shown) connected through the switch (31, 32) and a preset automatic response scenario Communication information in accordance with the above to obtain the promised information (e.g., the outgoing telephone number, the telephone number of the corresponding subscriber as information about any subscriber having the corresponding sound source to be listened to, the selection information on whether to change the sound source, etc.), On the basis of the obtained information, authentication of the connected subscriber is performed and communication with the sound source providing control server 70 is performed through the Internet network 60 to request and obtain a desired code, and the connection according to the scenario. It is composed of an automatic response service (ARS) device 55 for requesting a code change for the connected subscriber to the sound source providing control server 70 according to the selection of the subscriber. There.

4 is a flowchart of a sound source confirmation method in a subscriber-based ringback tone service according to an embodiment of the present invention, which will be described in parallel with its operation since it is applied to the apparatus of FIG. 3.

First, if any first subscriber mobile terminal (not shown) is connected to the ARS device 55 via the originating exchange 31 (or 31. 32 or less) (S401), the ARS device 55 Inquiry according to the set scenario, and the first subscriber responds to the query through key input of the mobile terminal (S402), and through such a query / response process, the ARS device 55 provides the necessary information as the promised information. Obtains telephone number information of an optional second subscriber (which may be the same as the first subscriber) selectively inputted from the first subscriber mobile terminal, and also the outgoing telephone number from the first subscriber mobile terminal, that is, the first subscriber mobile terminal. 1 The subscriber mobile terminal also obtains the phone number (S403).

For example, the ARS device 55 obtains an outgoing telephone number provided from the originating exchange 31 at the same time as the connection in step S401, that is, the telephone number of the first subscriber mobile terminal, and in step S402. Send a voice message, such as "Please enter the phone number of the subscriber you want to check the sound source" to the connected first subscriber mobile terminal. In response, when the first subscriber listens to the transmitted voice message through his mobile terminal and inputs the telephone number of the second subscriber mobile terminal, the ARS device 55 enters the key input in step S403. Receive and obtain phone number information.

Subsequently, the ARS device 55 uses the sound source providing control server based on the phone number information of the second subscriber among the phone number information of the first subscriber and the phone number information of the second subscriber as the obtained information. 70, ask the code information corresponding to the telephone number information of the second subscriber to request the corresponding sound source code (S404).

The sound source providing control server 70 searches for stored code information corresponding to the telephone number of the second subscriber in its database configured as shown in FIG. 5 in response to the request of step S404, and the searched code information. Is provided to the ARS device 55 and responds to step S404. For example, if the telephone number of the second subscriber is '293-XXXX', the stored code information '07' corresponding to the telephone number is recalled. Provided to the ARS device 55 (S405).

The ARS device 55, based on the code information '07' provided from the sound source providing control server 70 in step S405, the code information '07' in its database configured as shown in FIG. Search for the sound source # 7 as the stored sound source, send the searched sound source # 7 to the mobile terminal of the first subscriber through the exchange 31, and allow the first subscriber to listen. It is possible to check what the sound source (S406).

The ARS device 55 inquires according to the scenario with the first subscriber mobile terminal while the corresponding sound source # 7 is being transmitted as described in step S406 or after the transmission is completed repeatedly for a preset time or number of times. On the basis of the / response (S407), it is determined whether there is a sound source change request from the mobile terminal of the first subscriber (S408).

For example, while the corresponding sound source # 7 is being transmitted in step S406, a specific key promised for changing the sound source is selected from the mobile terminal of the first subscriber in step S407, or repeated for a predetermined time or number of times. After the transmission is completed, the ARS device 55 transmits a guide voice message, such as "If you do not want to change the sound source, press 2 to exit", to the mobile terminal of the first subscriber. If the first key is selected from the mobile terminal of the first subscriber in response, the ARS device 55 determines that there is a sound source change request in step S408.

If the ARS device 55 determines that there is a sound source change request as a result of the determination in step S408, the first subscriber telephone number (e.g., 294-0000) and the second subscriber telephone number (e.g., obtained in step S403) are determined. 293-XXXX), the sound source code change request is made to the sound source providing control server 70 (S409).

The sound source providing control server 70 stores the code information '17' stored in correspondence with the first subscriber telephone number '294-0000' in its database as shown in FIG. 5 in response to the request of step S409. 2 Change and store the stored code information '07' corresponding to the subscriber's telephone number '293-XXXX'. That is, the code information stored corresponding to the subscriber telephone number '294-0000' is changed and stored from '17' to '07' (S410).

As a result of step S410, the ringback tone substitute sound source for the outgoing call to the first subscriber mobile terminal is shown in FIG. 6 as the sound source # corresponding to the changed code '07' in the sound source # 17 corresponding to the previous code '17'. Is changed to 7. That is, the sound source listened to in step S406 is made into its own sound source.

On the other hand, if it is determined that there is a sound source change request as a result of the determination of step S408, the ARS device 55 determines whether termination is selected (S411), and if the termination is selected (S412), all processes are terminated (S412).

Further, the ARS device 55, upon trunk connection with the switchboard 31 in step S401, based on the first subscriber mobile terminal telephone number as the outgoing phone number provided from the switchboard 31, the connected first telephone number. Authentication of the subscriber may be performed, and it may be determined whether to perform the subsequent process of step S401 according to the authentication result.

As described in detail above, according to the method and apparatus for identifying a sound source in a subscriber-based ringback tone service according to the present invention, the subscriber-based ringback tone service can identify what a sound source of itself or another person does not occupy unnecessary trunk resources and calls. In addition to this, the effect of allowing the identified sound source to be its own sound source is created.
