Abstract

A method for providing a plurality of ring-back tones based on subscribers is provided to allow a caller to selectively enjoy a sound source suitable for his/her situation after listening to a guidance announcement. When an HLR(Home Location Register) receives a termination location information request message from an originating MSC(Mobile Switching Center), it includes ring-back tone service information from a callee and routing information received from a terminating MSC in a response message and provides it to the MSC(S101-S104). When the originating MSC requests a call connection to a corresponding MSC and sound source reproducing unit, the sound source reproducing unit requests sound source setting information of a corresponding termination subscriber from a DB server(S105-S107). The DB server transmits announcement sound source code information to the sound source reproducing unit(S108). The sound source reproducing unit transmits an announcement sound source to a caller(S109). When a particular DTMF(Dual Tone Multi-Frequency) is received from the originating MSC, the sound source reproducing unit transmits a corresponding ring-back tone sound source to the caller(S110,S111).

Stores and manages the guide sound source code information for the announcement set by the subscriber for selection guidance.

The sound source reproducing apparatus 210 receives ringback tone sound source code information and guide sound source code information for each address number set for each subscriber from the DB server 220, and transmits the guide sound source to the calling exchange 30. Detecting the DTMF signal transmitted from the source exchanger 30 transmits the ringback tone sound source according to the ringback tone source code information for each address number to the source exchanger 30.

In addition, the ringback tone service apparatus 200 is also connected to the PSTN network 70, which is a general wireline telephone network, detects DTMF signals transmitted from a wireline switching center (not shown) to ring the wireline telephone terminals 300 and 310. Send back tones.

On the other hand, the home location register 40, which manages the subscriber's additional service information, manages the subscriber's ringback tone service information including whether the subscriber uses the ringback tone service and an activation state, and when a call is attempted from the originating exchange 30, In the case of a ringback tone service user according to the subscriber ringback tone service information, IP information of a sound source reproducing apparatus is provided to the originating exchange 30. Accordingly, the call exchanger 30 connects a call with the sound source playback device 210 according to the received IP information of the sound source playback device 210.

The DB server 220 stores the information on the designation relationship between ringback tone source codes for each speed number and the guide sound source code information corresponding to the announcement set by the subscriber as service information for each subscriber. ) Transmits the information to the sound source playback device 210 according to the request. The ringback tone sound source file and the guide sound source file may be stored in the DB server 220, the sound source reproducing apparatus 210, or a separate storage device.

The sound source reproducing apparatus 210 performs a guide sound source transmission, DTMF recognition, and ringback tone transmission function according to the information received from the DB server 220.

On the other hand, a ringback tone service subscriber uses a mobile communication terminal (100) (110) to the sound source playback device 210 through a packet data service node (50) (51) and a data core network (60) (61). Access to the sound source reproducing apparatus 210 by using the computer terminal 400 and other wired / wireless internet communication terminals through the wired / wireless Internet 80 to obtain sound connection information of ringback tones for the guide sound source and the speed dial number. When the external CP 221 provides a plurality of sound source and guidement setting function menus, the external CP 221 may perform the external CP 221.

In addition, the subscriber should set a sound source for each address number corresponding to the announcement.

On the other hand, in case the caller does not input the speed dial number, the subscriber may set a representative sound source among the plurality of ringback tone sound sources. At this time, the DB server 220 should have more information of the representative sound source code of the plurality of sound source codes, the sound source playback device 210 should transmit a sound source corresponding to the representative sound source code when the DTMF is not received.

2 is a flowchart illustrating a subscriber-based multiple ringback tone service method according to the present invention.

As shown, when any caller calls the ringback tone service subscriber of the present invention (hereinafter referred to as the called subscriber) to request a call connection, the calling side exchange 30 sends a call location to the home location register 40. Request information (Location Request) (S101).

The home location register 40 requests routing information from the called side exchange 31, and accordingly, the called side exchange 31 responds by providing routing information to the home location register 40. (S102).

The home location register 40 transmits the routing information to the originating exchange 30 and responds to step S101. In particular, the home location register 40 checks the subscriber profile in response to the service of the present invention, that is, a ringback tone service. After confirming whether the subscriber (S103), if not the subscriber includes only the routing information to the destination exchange in the response message for the incoming location information request to the originating exchange 30, and if the subscriber within the response message Routing information including service setting information and routing information to the sound source reproducing apparatus 210 (for example, a number that can be routed to the sound source reproducing apparatus 210: CRBT-RoutingDigits) is given to the source exchanger 30 ( S104).

The calling side exchange 30 requests a call connection only to the called side exchange 31 based on the response message provided from the home location register 40 to form a mutual call path (S105), or at the same time. A call connection is also selectively requested to the sound source reproducing apparatus 210 to form a mutual call path (S106).

Subsequently, when a call path is established with the call exchanger 30 in step S106, the sound source reproducing apparatus 210 requests the subscriber server sound source setting information from the DB server 220 based on the called phone number information. In operation S107, the DB server 220 transmits the guide sound source code and the ringback tone sound code for each address number set by the called party to the sound source reproducing apparatus 210 (S108).

The sound source reproducing apparatus 210 transmits the guide sound source corresponding to the received guide sound source code to the caller through the call exchanger 30 (S109), and the caller calls a specific shortcut number according to the announcement after listening to the guide sound source. If the input is received and recognized DTMF from the source exchange (30) (S110), out of a plurality of ringback tone source set by the called subscriber transmits the ringback tone source for the corresponding shortcut number to the calling side exchange (30). (S111).

On the other hand, although not shown in the figure, when the caller does not enter any shortcut number, the sound source playback device 210 is preferably to transmit the ringback tone source set by the called party as the representative sound source, in this case, DB server 220 may further store the representative sound source code information among the plurality of ringback tone sound source codes, and transmit the representative sound source code information in step S108.

Subsequently, the calling party exchange 30 requests call release from the sound source reproducing apparatus 210 when the called subscriber picks up the phone while the caller select sound is being transmitted to the ringback tone as described above (S112). The sound source reproducing apparatus 210 releases the call, and at the same time, a call is made between the caller and the called subscriber through the call path mutually formed with the called side exchange 31 (S113).

Therefore, according to the subscriber-based multiple ringback tone service method of the present invention, the ringback tone service subscriber can set more various sound sources according to the situation, and the caller does not listen to the sound source set by the called subscriber uniformly regardless of their will. After listening to the guidement, you can select the appropriate sound source according to your situation.
