The present invention relates to a method for providing a multimedia ring back tone service instead of a ringback tone to a calling terminal. More particularly, when a called party registers a service, the ringing tone is pre-registered as a calling terminal. By delaying the call notification for a certain time, when the calling subscriber attempts to access the call, the call connection sound is transmitted to the calling terminal for the time set by the called subscriber, and then the ring signal is transmitted to the called terminal. The present invention relates to a method for providing a ring back tone service through a call notification delay.

In general, in order to make a call connection between the calling terminal and the called terminal, when the dialing terminal attempts to dial, the calling exchange and the called exchange exchange messages to each other, and then the ringback tone signal is transmitted to the calling terminal. A ring signal is transmitted to the called terminal. As such, when the ring signal is transmitted to the called terminal and the call is received from the subscriber side, the ringback tone signal of the calling terminal is cut off and a call path is formed to enable a call between the called / calling terminals.

Recently, the telecommunications company has developed and serviced a variety of sound sources such as music and advertisements while developing and servicing a product to service a ring back tone instead of the ringback tone delivered to the calling terminal, but the ring back tone and the called terminal delivered to the calling terminal. When the hook-off signal is transmitted from the called terminal, because the ring signal transmitted to the call is simultaneously transmitted, the call path is disconnected while the call connection sound transmitted to the calling terminal is cut off.

However, when initiating the RBT service using the calling terminal as in the prior art, the called party receives the call notification without knowing how much the ringing subscriber has heard the RBT even if he wants to deliver the RBT to the calling party for a predetermined time. Since the call is received, the subscriber has difficulty in delivering the ring back tone for the desired time to the subscriber even when the advertisement or notification message or the general ring back tone using the multimedia ring back tone is provided.

Referring to the drawings, the present invention is to provide a method for providing a predetermined multimedia ring back tone instead of a ringback tone signal to the calling terminal, when the dialing signal is transmitted from the calling terminal, the receiving subscriber registered to the calling party's terminal The present invention discloses a method of transmitting a predetermined ring back tone signal (ring back tone signal) for a predetermined time and then transmitting a call notification signal (ring signal) to a called terminal.

Referring to FIG. 1, reference numeral 10 denotes an originating terminal, 20 an originating exchange, 30 an incoming exchange, and 40 an incoming terminal.

The present invention is a service system using a general telephone switching network consisting of the source exchanger 20 and the destination exchange 30, when the originating terminal 10 dials to the destination terminal and attempts to make an outgoing call. Retrieves the stored information of the called subscriber registered in the subscriber information storage server 70 based on the outgoing call transmitted from the subscriber, and if the called subscriber is registered in the service, the ring tone uploaded by the called subscriber instead of the usual ringback tone signal The service controller 50 for controlling the system to be provided to the calling terminal 10, and stores the ring back tone uploaded by the called subscriber in its own local storage medium, and in the call originated from the calling terminal 10 Based on the analyzed called party information (telephone number) under the control of the service controller 50, a ring back tone signal mapped to the subscriber ID Include; (Intelligent Peripheral 60) via the originating exchange (20) IP system that allows play to the calling terminal 10.

The subscriber information storage server 70 stores information according to individual subscribers, for example, information such as subscriber ID, subscriber name, subscriber telephone number, call notification delay time and ring back tone ID in a storage table as shown in FIG. The service controller 50 analyzes the outgoing call of the calling terminal, searches whether the same called number is registered in the storage table of the subscriber information storage server 70, and controls the IP system 60 when the same telephone number exists. The ring back tone stored in the local storage medium is transmitted to the calling terminal 10 through the calling exchange 20, wherein the subscriber's telephone number is at least one telephone number, a number band, a representative number, and a softphone. It is good to enter address.

According to the present invention, when the client, that is, the called subscriber, accesses the service management server 80 through the Internet network and uploads the call ring tone for the information about the information stored in the subscriber information storage server 70, the service management server 80 Mapping the ring back tone uploaded from the called subscriber with the ring back tone ID and storing it in the IP system 60, and storing other subscriber ID, subscriber name, subscriber phone number, call notification delay time and ring back tone ID, etc. 70) to start the service.

In addition, when a subscription procedure for using a service is requested by the client (90) by accessing the service management server (80), the service management server (80) inputs subscription information necessary for subscription to the called party. When a request is made and subscriber information is input in response, a service subscription for the present invention is made. Subscriber information provided during the subscription procedure is stored in the subscriber information storage server 70 in the form of a table as shown in FIG. 2, and the ring back tone is mapped to the subscriber ID and stored in the database DB of the storage medium of the IP system 60. Stored.

According to a preferred embodiment of the present invention, the ring tone information stored in the IP system 60 includes a voice, a video, a still image, and can be made of a combination thereof to increase the advertising effect.

Hereinafter, a method for providing a ring back tone service according to the present invention will be described with reference to the procedure of FIG. 3.

In the method of providing a ring back tone service according to the present invention, when a called subscriber requests a soft ring tone service to a communication service provider and the information of the called subscriber is registered in the subscriber information storage server 70, the called subscriber registers with the calling terminal prior to providing the service. The procedure for providing the ring back tone is as described above. Therefore, the following description assumes that the incoming subscriber is already registered with the service.

Referring to FIG. 3, when the called party registers the service to the communication service provider as described above, when the calling subscriber tries to connect to the call by dialing the called number using the calling terminal 10, the calling terminal ( The originating call of 10) is transmitted to the originating exchange 20 through a wired / wireless / VoIP network, and the originating exchange 20 delivers the originating call received from the originating terminal 10 to the service controller 50 (S31). -S32).

The service controller 50 analyzes the outgoing call transmitted from the originating exchange 20, extracts the called number, and inquires whether the incoming subscriber stored in the subscriber information storage server 70 subscribes to the service based on the called number. . If the called party is registered in the ring back tone service with the call notification delay time set, the service controller 50 requests the call leg separation from the calling switch 20, and the calling switch 20 calls the call leg. The originating leg and the receiving leg are separated by the call leg separation request of the service controller 50. On the contrary, when the service is not registered, the originating call is transferred to the terminating exchange 30 according to a normal procedure. (S33-S36).

On the other hand, when the step S35 is completed, the service controller 50 controls the originating exchange 20 and the IP system 60 to form a call path, and at the same time of the incoming subscriber stored in the subscriber information storage server 70 The call ring tone ID is transmitted to the IP system 60, and the call ring tone mapped to the ID is based on the call ring tone ID provided by the service controller 50 through the call exchanger 20. Instead of the ringback tone signal, it is transmitted to the calling terminal 10 (S37).

 At this time, since the call exchanger 20 has already formed a call path with the IP system 60 under the control of the service controller 50 and is performing a service corresponding to the call ring tone ID, the call exchanger 20 receives the call exchanger ( The ringback tone signal transmitted from 30) is not connected to the calling terminal 10, and thus, the calling terminal 10 hears a ring back tone registered by the called subscriber instead of the ringback tone.

As such, the call controller 10 checks the call notification delay time while the call connection tone registered by the called subscriber is provided to the calling terminal 10 instead of the ringback tone. If so, the service controller 50 requests the originating switch 20 to connect the calling leg and the called leg, and when the incoming / outgoing leg is connected, a call alerting signal is transmitted to the called terminal 40. The receiving terminal 40 starts to ring a call notification sound (ring tone or ring signal) (S38-S41).

In this way, the call is made from the calling terminal 10, the call notification signal is transmitted to the called terminal 40 in a state in which a call connection sound is provided to the calling terminal 10 according to the call notification delay for a predetermined time, and then the called terminal ( 12) when the call is received, a call response signal is transmitted to the destination exchange 30, and the destination exchange 30 transmits the response signal to the source exchange 20, and the source exchange 20 to the service controller 50. Transfer the call response of the called terminal (S42-S43).

Subsequently, the service controller 50 transmits a call ring tone stop message to the IP system 60 according to the call response signal transmitted from the originating exchange 20, and at the same time, the originating terminal 10 and the IP system 60 By cutting off the connected call path, the ringing tone transmitted to the calling terminal 10 is interrupted and a call path is formed between the calling exchange 20 and the called exchange 30 so that a call can be made between the calling subscriber and the called party. (S44).

Subsequently, when the called subscriber disconnects the call, the called terminal 40 sends a REL (Release) message to the called exchange 30, and the called exchange 30 sends an REL message to the calling exchange 20. The exchange 20 disconnects the call with the originating terminal 10 and sends the RLC message to the destination exchange 30 to complete the call disconnection (S45-S47).

The above-described embodiments are intended to help the understanding of the present invention, and the present invention is not limited to the above-described embodiments and can be variously modified and implemented by those skilled in the art without departing from the technical spirit of the present invention. .

As described above, according to the present invention, since the called party can set the call notification delay time for the ring back tone, the call notification can be received after the call ring tone is transmitted to the caller as much as the delay time. This allows the caller to answer the call after the caller wants to receive the ringtone for as long as he or she wants.Then, the caller can hear the caller for the time set by the caller for the advertisement or notification message. have.

In addition, the present invention because the incoming subscriber can change or delete the information on the ring back tone through the service management system has the effect that the incoming subscriber can be promoted by delivering new information to the calling party.
