The present invention relates to a method for providing a service provider designated sound source to a calling subscriber in a call waiting state, and more particularly, a called subscriber in a state in which a calling subscriber makes a call and attempts to call a called subscriber terminal. It relates to a method for providing to the calling subscriber a promotional sound source of the subscribed service provider. Furthermore, the present invention relates to an improvement of Korean Patent Application No. 2003-12535 (name of the invention: notification of wired and wireless communication service providers waiting for call connection) filed by the applicant of the present invention.

Here, the service provider designated sound source may be a melody or a voice for promoting a service provider, or may be a specific melody or a specific promotional comment. In other words, this refers to a sound source for providing in common to all outgoing subscribers who call subscribers who subscribe to their services.

Recently, with the explosive increase in the number of subscribers of mobile communication terminals, service providers are developing and providing various additional services to attract customers.

Among these additional services, a service that can express a subscriber's personality is becoming popular. For example, when a subscriber calls the other party, a call ring tone set by the other party instead of the general ring back tone is used for the calling subscriber. Coloring services, such as songs, sound effects, fun sounds, and comments, are popular.

1 is a block diagram of a general subscriber-based ring back tone providing system.

The system for providing a ring back tone communicates with the home location register (10) through a home location register (HLR) 10 and a common line signal (No. 7) network 20 based on a signaling transfer protocol. Switch (O_MSC / VLR, T_MSC / VLR) (31,32), sound source providing device 50 is connected to the No.7 network 20 and communicates with the switch (31,32) through a gateway 40, A sound source providing control server 70 in data communication with the sound source providing apparatus 50 through an IP network 60, a subscriber storage database 80 connected to the home location register 10 through the IP network 60, It is connected to the IP network 60 through the gateway 90 includes a web server 100 for communicating with the sound source providing apparatus 50 and the sound source providing control server 70.

The home location register (10) stores subscriber information, and stores first information on subscription to a ringback tone service and second information for routing to the sound source providing apparatus (50) as profile information on a called subscriber. The information is set and stored as supplementary service subscription information of the called party profile.

The exchanges 31 and 32 communicate with the home location register 10 when registering the location of the called party, receive and store the preset first and second information, and store the received first when requesting a call connection of the called party. And receiving a sound source for replacing a ringback tone by communicating with the sound source providing apparatus 50 based on the second information, and providing the received sound source as a ringback tone replacement sound to the caller.

The sound source providing device 50 stores various sound sources and communicates with the exchanges 31 and 32 through the gateway 40 to provide the stored sound sources to the exchange.

The sound source providing control server 70 communicates with the sound source providing apparatus 50 through the IP network 60, and the type of sound source to be provided by the sound source providing apparatus 50 to the switchboards 31 and 32. It determines by referring to the identification information of the called subscriber, the caller identification information corresponding to the call connection request.

The web server 100 is connected to the sound source providing device 50 or the sound source providing control server 70 through the IP network 60, to add the sound source stored in the sound source providing device 50, or to the sound source This is for changing the information for specifying the sound source of the provision control server 70 and the corresponding sound source code, which can be performed by a subscriber through a web page provided by the web server 100.

If any caller calls the called subscriber and requests a call connection, the calling switch 31 requests the home location register 10 for the location information of the called subscriber terminal.

The home location register 10 requests routing information from the destination exchange 32 according to the request, and accordingly, the destination exchange 32 transmits routing information, that is, a TLDN (Temporary Local Directory) to the home location register 10. Answer by giving a number).

The home location register 10 transmits routing information of the destination exchange to the originating exchange 31, and thus the originating exchange 31 trunks to the destination exchange 32 based on the routing information. Requests call connection to form mutual channel.

Subsequently, the destination exchange 32 receives the service setting information received from the home location register 10 at the time of registering the location and the subscriber is a subscriber of the service and activates the service based on routing information to the sound source providing device 50. If it is determined that the state, based on the routing information request the ISUP call connection to the sound source providing apparatus 50 to form a cross-trunk call path, at this time also provides the incoming telephone number and the outgoing telephone number. 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 based on the received incoming and outgoing telephone number information. The sound source providing control server 70 searches for a designated sound source code in association with the received incoming and outgoing telephone number according to the query of the sound source providing device, and transfers the found sound source code to the sound source providing device 50. do. The sound source providing apparatus 50 transmits a sound source corresponding to the received sound source code from the pre-stored sound source to the caller through the formed call path as a substitute sound instead of ringback tone.

On the other hand, the destination exchange 32, when the incoming subscriber receives a call while the replacement sound is being transferred instead of the ringback tone as described above, and requests the release of the ISUP call to the sound source providing device 50, the sound source providing device 50 To release the call. At the same time, the destination exchange allows a call to be made between an originating subscriber and a destination subscriber through a call path mutually formed with the originating exchange 31.

Meanwhile, in the related art, different identification numbers are provided for each mobile communication service provider (operator), so when a caller makes a call to the other party's mobile terminal, the service provider identification number is immediately known to know who the other mobile communication service provider has subscribed to. Can be. The same is true of landline phones.

However, once the phone number is given, the subscriber can choose the phone number, and if the service provider changes, a number portability system is introduced that can be maintained for a lifetime. will be. In this case, the service identification awareness by the current service provider identification number will disappear. Accordingly, even in such a case, there is a need for a method for allowing the caller to know who the service providers are subscribed to, so that the service provider can be unknowingly advertised.

Therefore, the present invention provides a sound source for the service provider subscribed to by the subscriber in the state in which the calling subscriber makes a call and attempts to make a call to the called subscriber's terminal, thereby providing discrimination and pride in selecting a service provider. And a method for improving the advertisement effect of the service provider.

A first embodiment according to the present invention for achieving the above object is a service provider-designated sound source in a system including an originating exchange, a destination exchange, a home location register, a visitor location register, a sound source providing device and a sound source providing control server. A method for providing a caller, the method comprising: a first step of analyzing a received call connection request message when the sound source providing apparatus receives a call connection request from the destination exchange; A second step of reproducing the sound source designated by the service provider and providing it to the caller when the called party subscribes only to the service provider designated sound source providing service as a result of the first step; And a third step of requesting a call release to the destination exchange when the reproduction of the sound source designated by the service provider of the second step is completed.

Preferably, in the first embodiment of the present invention, when the called party subscribes to the service provider-designated sound source providing service and the call connection sound providing service, the sound source providing device designates a sound source designated by the service provider. A fourth step of playing and providing the caller to the caller; A fifth step of, by the sound source providing device, querying the sound source providing control server for a sound source code registered and registered by the called party; And a sixth step of, if the response to the query is received, immediately playing the corresponding sound source and providing it to the caller as soon as the reproduction of the fourth step is completed.

Preferably, the sound source providing apparatus identifies the service subscription type of the called party through the routing number in the call connection request message received from the called exchange.

A second embodiment of the present invention provides a service provider-specific promotional sound source in a system including a calling exchange, a called exchange, and a home location register, wherein the calling exchange corresponds to a called party's location by a caller's call request. A first step of receiving routing information of the called exchange and information indicating whether the called party subscribes to a service; A second step of, when the called party subscribes to the service, the calling exchange sends the announcement announcement recorded by the service provider in advance to the calling party; And a third step of the originating exchange requesting an ISUP call connection to the destination exchange based on the routing information.

A third embodiment of the present invention provides a service provider-specific promotional sound source in a system including an originating exchange, a terminating exchange, and a home location register.

Hereinafter, with reference to the accompanying drawings for the embodiment of the present invention will be described in detail the configuration and operation.

2 is a process flow diagram according to a first embodiment of the present invention.

The first embodiment of the present invention is achieved by using a general subscriber-based ring back tone providing system.

When a call connection request is received by any caller, the calling exchange to which the caller belongs requests the location information of the called terminal to the home location register (HLR) where the called party requested by the caller is registered (101).

The home location register requests the routing information to the destination exchange in which the called terminal is location registered according to the location information request of the originating exchange (102). Accordingly, the visitor location register (VLR) of the destination exchange side assigns a temporary local directory number (TLDN) for the called terminal and responds to the home location register (103).

The home location register sends 104 routing information (TLDN) of the destination exchange to the originating exchange. Accordingly, the originating exchange requests an ISUP call connection to the destination exchange based on the routing information (105).

The called exchanger receives the service profile of the called subscriber from the home location register during the location registration process and stores it in the visitor location register (VLR). Accordingly, the destination exchange can know what services the called party has subscribed to and what operations should be performed to provide the services subscribed to by the called party. When the destination exchange receives an ISUP call connection request containing routing information (TLDN) from the originating exchange, it checks whether the service is active. If it is not activated, the destination exchange performs normal processing, and if it is activated, requests the ISUP call connection to the sound source providing apparatus using the stored routing information (106). At this time, the destination exchange transmits the ISUP call connection request message by including the routing number in the destination subscriber profile. For example, when the called party subscribes only to the coloring service, a routing number corresponding to the coloring service (for example, "1501") is included. If the called party subscribes only to the service provider designated sound source providing service of the present invention, the corresponding subscriber corresponds to the coloring service. A routing number (eg, "1502") is included, and a corresponding routing number (eg, "1503") is included when the called party subscribes to both the coloring service and the present invention service. Here, each subscriber does not have to go through a separate service subscription procedure for the service. However, only subscribers who have refused to provide the service need to confirm whether they agree to provide the service. The sound source for providing the service is provided from a sound source providing apparatus for providing a conventional coloring service.

The sound source providing apparatus performs a processing procedure as shown in FIG. 3 based on the routing number and the incoming and outgoing telephone number information in the ISUP call connection request message transmitted from the destination exchange, which will be described later. The flowchart shown in Fig. 2 is a processing flowchart in the case of subscribing to both the present service and the coloring service.

The sound source providing apparatus transmits the promotional sound source designated and registered by the service provider (business operator) to the caller based on the information provided from the destination exchanger (107). Here, the service provider-designated promotional sound source is preferably about 2 seconds in size. At the same time, the sound source providing apparatus queries the sound source code for the coloring service registered by the called subscriber to the sound source providing control server (108).

The sound source providing control server searches for a designated sound source code in association with the provided incoming and outgoing telephone number according to the query of the sound source providing device, and transfers the found sound source code to the sound source providing device (109). The sound source providing apparatus transmits a sound source corresponding to the received sound source code from the pre-stored sound source to the caller through the formed call path as a substitute sound replacing the existing ring back tone (110).

On the other hand, when the incoming subscriber receives a call while the sound source is being transferred instead of the ringback tone as described above, it requests the release of the ISUP call to the sound source providing apparatus (111). Accordingly, the sound source providing apparatus terminates the sound source reproduction. At the same time, the destination exchange allows the call to be made between the calling party and the called party through the call path interworked with the calling exchange (112).

3 is a process flowchart of a sound source providing apparatus according to the present invention.

When the sound source providing device receives a call connection request including a routing identifier and information of an incoming and outgoing subscriber from the destination exchange (201), it analyzes the received request message (202). Through the analysis, the sound source providing apparatus may check a service type subscribed to by the called subscriber (203). The sound source providing apparatus plays the promotional sound source designated by the service provider (operator) when the called subscriber subscribes only to the service (204), and when the reproduction is completed, transmits the ISUP call release request to the called exchange (205). Accordingly, the terminating exchange releases the ISUP call with the sound source providing apparatus, and transmits the ringback tone provided by the conventional exchange to the sender. When the called party subscribes only to this service, the difference from the general coloring service is that the sound source providing device sends an ISUP call release request to the called exchange as soon as the playing of the sound source is completed. Of course, the sound source providing device may be to continue to provide a promotional sound source as in the existing coloring service.

On the other hand, when the called subscriber subscribes to both the service and the coloring service, as described above, the promotional sound source designated and registered by the service provider (operator) is transmitted to the caller (206). At the same time, the sound source providing apparatus queries the sound source code for the coloring service registered by the incoming subscriber to the sound source providing control server (207).

The sound source providing control server searches for a designated sound source code in association with the received incoming and outgoing telephone number according to the query of the sound source providing device, and transfers the found sound source code to the sound source providing device (208). The sound source providing apparatus transmits a sound source corresponding to the received sound source code from the previously stored sound source to the caller through the formed call path as a substitute sound replacing the existing ring back tone (209).

On the other hand, when the called subscriber subscribes only to the coloring service, step 207 or less for providing a general coloring service is performed.

4 and 5 illustrate second and third embodiments for providing the service.

FIG. 4 is a broadcaster designation announcement broadcast from the originating exchange, and FIG. 5 is a broadcaster designation announcement broadcast from the destination exchange. Let's look at this in detail.

When a call connection request is received by any caller, the call exchanger to which the caller belongs requests the location information of the called terminal to the home location register (HLR) to which the called party requested by the caller is registered (301, 302).

The home location register requests routing information from the destination exchange to which the destination terminal is located in accordance with the location information request of the originating exchange (303). Accordingly, the visitor location register (VLR) at the destination exchange side allocates a temporary location directory number (TLDN) for the called terminal and responds to the home location register (304).

The home location register transmits routing information (TLDN) of the destination exchange to the originating exchange (305). At this time, the home location register notifies the calling subscriber whether the subscriber subscribes to the service so that the service can be provided. Accordingly, the originating exchange sends the announcement to the caller, which the operator designated and recorded in advance (306). In this case, the announcement broadcast may be a recorded broadcast or may be a specific sound source. The originating exchange then requests an ISUP call connection to the destination exchange based on the routing information (307). Accordingly, a call path is established between the calling exchange and the called exchange (308), and the called subscriber and the calling subscriber can talk.

5 is a processing flowchart for providing the service at the destination exchange. If the service providers of the originating exchange and the destination exchange are different, the service should be provided at the destination exchange. For example, if a landline subscriber calls a mobile subscriber, the service provider will be different. Take a look at this.

When a call connection request is received by any caller, the call exchanger to which the caller belongs requests the location information of the called terminal to the home location register (HLR) to which the called party requested by the caller is registered (401, 402).

The home location register requests routing information from the destination terminal to which the destination terminal is location-registered according to the location information request of the originating exchange (403). Accordingly, the visitor location register (VLR) on the destination exchange side allocates a temporary location directory number (TLDN) for the corresponding destination terminal and responds to the home location register (404).

The home location register sends (405) routing information (TLDN) of the destination exchange to the originating exchange. The originating exchange requests the ISUP call connection to the incoming communication based on the routing information (406). Accordingly, the destination exchange transmits a response according to the ISUP call connection request to the originating exchange (407). At the same time, the destination exchange retrieves the service profile of the called party and, when the called party subscribes to the service, transmits an announcement or a specific sound recorded by the operator in advance through the established call path to the caller (408). On the other hand, the destination exchange performs only conventional call processing procedures when the called subscriber does not subscribe to the service.

As described above, according to the present invention, by providing information of the service provider (operator) to which the called party subscribes to the calling party until the caller attempts to access the call to the called party's terminal, the called party joins the called party. Information about who can be notified to the sender, and by providing this information to the user can give a differentiation and pride to the operator selection, it can provide an indirect advertising effect.
