The present invention relates to a real-time streaming on-demand bell service providing method and a real-time streaming on-demand bell service providing system for transmitting the content bell media information to the called terminal receiving the call request by the streaming method, and implements it as a call signal in the called terminal. will be.

Normally, when a call request is received by the called terminal from a calling terminal which has a request for a telephone call, the called terminal implements a preset ring tone to notify the user of the called terminal that there is a call request from a predetermined calling terminal.

The ring tone sets a material to be implemented as a call signal among music, sound effects, and songs supported by the user of the called terminal, and implements the set call signal in the called terminal as the call request is received by the called terminal. .

However, a method of setting a ringtone supported by a called terminal has a limitation in selecting a ringtone from a limited resource, and thus does not sufficiently satisfy a user's request of a called terminal for implementing various ring sounds as a call signal.

In order to remove the limitation of the ringtone, for example, a ringtone service for downloading a ringtone from the Internet to a called terminal has been provided in a generalized manner, whereby a user of the called terminal can set a ringer of a variety of genres and types as a call signal of the called terminal. have.

However, despite this improved form of ringtone, the ringtone is merely a call signal, and there is still a limitation that it does not contain any information other than that the call request has been received.

However, in order to overcome the limitation of the conventional ringtone service, in Korean Patent Application No. 10-2000-0045664 (hereinafter referred to as "advanced ringtone advertising model"), the user of the mobile communication terminal downloads the ringtone sound and characters for advertising, Whenever a call is received by the mobile communication terminal, a technology for displaying an advertisement character on the screen of the mobile communication terminal and outputting an advertisement telephone ring to perform an advertisement is disclosed. By using the preceding ringtone advertising model, by using the ringtone as an advertising means, it is possible to promote advertisements for advertisers every time a telephone call is requested, so that the advertisement information can be included in the ringtone previously existing in a simple call signal.

However, the preceding ringtone advertising model stays in a manner in which a user downloads and stores a specific ringtone including advertisement information in a terminal, and automatically stores a ringtone when a call request is received in the terminal. That is, the preceding ringtone advertisement model is a technology that merely implements a predetermined call signal automatically like a normal ringtone except for using advertisement information as a ringtone.

If it is possible to implement valuable information such as advertisement as a call signal, but the ringtone implemented in the terminal can be set to be different each time a call request is received, the user of the called terminal may have a continuous interest in the ringtone. Various information may be obtained by the call signal.

Therefore, by using the call signal as an information providing tool, there is an urgent need for an implementation model of a new call signal capable of providing advertisements, news, music, movies, and other useful information to users of the called terminal using only the call signal. . In addition, whenever a call request is received by the called terminal, a new content bell is transmitted to the called terminal, thereby requiring an implementation model of a call signal capable of continuously providing new information to a user of the called terminal.

The present invention has been made to solve the above problems, the bell information service providing method and real-time streaming to provide useful information using the call signal by implementing a variety of media information as the call signal at the time of the call request Its purpose is to provide a custom bell service provision system.

In addition, the present invention is to implement the content bell media information as a call signal in the receiving terminal receiving the call request, the real-time streaming on-demand ring service providing method and real-time streaming provided by the content bell media information to the receiving terminal by the streaming method Its purpose is to provide a custom bell service provision system.

In addition, the present invention, if there is a content bell rejection setting in the receiver terminal, receiving the content bell rejection request from the receiver terminal by limiting the transmission of the receiver terminal of the content bell media information by real-time streaming on-demand An object of the present invention is to provide a bell service providing method and a real-time streaming on-demand bell service providing system.

In accordance with an embodiment of the present invention for achieving the above object, a method for providing a real-time streaming on-demand bell service using a call server and a content bell server, the call server in response to a call request received from the calling terminal to the called terminal; Transmitting a content bell request message to the content bell server in response to a content bell request received from the called terminal in response to the call request message at the call server; and at the content bell server And transmitting content bell media information to the called terminal in response to the content bell request message.

In addition, as a configuration for achieving the above object, the real-time streaming on-demand bell service system transmits a call request message to the called terminal in response to a call request received from the calling terminal, and receives the call request message from the called terminal. A call server for generating a content bell request message in response to the content bell request, and a content bell server for transmitting content bell media information to the called terminal in response to the generated content bell request message from the call server, If the call server receives a content bell rejection request from the called terminal with respect to the call request message, the call server switches to the general call by preventing the content bell request message from being transmitted to the content bell server in response to the content bell rejection request. It features.

Hereinafter, a method for providing a real-time streaming on-demand bell service and a system for providing a real-time streaming on-demand bell service will be described with reference to the accompanying drawings.

The "content bell media information" continuously used in the present specification is a kind of call signal implemented in the called terminal according to a call request from the calling terminal, and the user of the calling terminal (hereinafter referred to as caller) requests a telephone call. For example, video, audio, and text information of advertisements, news, music, movies, and other useful contents for notifying the user of the called terminal (hereinafter referred to as called party) may be referred to. That is, the called terminal receiving the call request notifies the called party that the called terminal has a call request by implementing content bell media information such as video, audio, and text information as a call signal.

In addition, the content bell media information is multimedia data provided by a specific content providing server, and may be received from a content provider having a predetermined contract relationship with the system operator and maintained in, for example, a storage means of the content bell server.

In particular, the content bell media information according to the present invention may correspond differently to each called terminal, and the real-time streaming on-demand bell service providing system according to the present invention receives the content bell media information corresponding to the called terminal in response to the call request. Can be sent to the terminal. In addition, as another example, the real-time streaming on-demand ring service providing system of the present invention may randomly extract one of the one or more content bell media information and send it to the called terminal whenever a call request is received by the called terminal. .

1 is a diagram illustrating a service network configuration for providing a real-time streaming on-demand bell service, and is a view for explaining a schematic operation of an apparatus driven according to the control of a real-time streaming on-demand bell service providing system according to the present invention.

The real-time streaming on-demand bell service providing system sends the content bell media information of the content providing server to the called terminal in real time by streaming method whenever a call request is received by the called terminal. To be implemented as a call signal at the called terminal As described above, the real-time streaming on-demand bell service providing system can identify the called terminal receiving the call request and send specific content bell media information to the called terminal, or randomly whenever a call request reaches the called terminal. The extracted content bell media information may be transmitted to the called terminal.

First, the call server receives a call request from the calling terminal, identifies a called terminal requested by the calling terminal, and forms a call connection path between the calling terminal and the called terminal. In particular, the call server determines whether the identified called terminal (called subscriber) is subscribed to the real-time streaming on-demand bell service. At this time, when subscribed, the call server transmits a call request message relating to generation of a content bell request to the called terminal together with the call request, so that a call request received by the called terminal is related to the transmission of content bell media information. Can be recognized.

In addition, the call server checks whether the called party of the call request terminal is subscribed to the content bell service of the present invention, and to transmit the call request message only to subscribers subscribed to the content bell service, the system operator of the present invention The receiver may enter into a predetermined contract relationship related to the content bell service, and the real-time streaming on-demand bell service providing system may collect, for example, the personal information of the called party and a list of content bell media information to be provided. And data relating to the type of called terminal to be used. The process of signing the contract of the called party for the content bell service or checking whether any called party subscribes to the content bell service may be applied mutatis mutandis which can be devised by those skilled in the art and will not be described in detail herein. .

In addition, the call server may perform a determination process as to whether the content bell media information can be implemented in the called terminal. This determination process can be performed, for example, by analyzing data relating to the type of called terminal collected from the called party in contract with the system operator. As a result of the determination processing, when the call requesting terminal determines that the content bell media information cannot be implemented, the real-time streaming on-demand bell service providing system transmits only a general call request to the called terminal without a content bell call request message.

An application server is a system that provides an execution environment for service logic for a real-time streaming on-demand bell service, and may be operated as part of a call server. The call server is a system that provides functions such as call control, subscriber processing and management, number translation and routing, and additional services for call communication between terminals. In addition, H323, SIP, MGCP, MEGACO / H.248, SIGTRAN, RADIUS and other protocols are provided to guarantee connectivity to all existing networks.

The content bell server is a server device that can provide a multimedia streaming service in real time under the control of a call server / application server. The content bell server is a system capable of transmitting multimedia data stored in the server device or stored in another content server to the user terminal. . In addition, it can support protocol interfaces such as H323, SIP, MEGACO / H248, MGCP, SIGTRAN, RTP / RTCP, and if the media attributes such as the codec of the called terminal and the content bell and the bandwidth of the transmission means are different, It is a system that can provide coding function and real time packet forwarding function.

The content bell server stores the content bell media information provided by the content providing server, and when receiving the content bell request message from the call server, extracts the stored content bell media information and transmits the content bell media information to the called terminal. That is, the content bell server transmits the content bell media information to the call requesting terminal while maintaining the content desired by the content providing server, such as advertisements, news, and other useful contents as the content bell media information. In particular, the content bell server may randomly (randomly) transmit content bell media information to be sent to the called terminal at the time of receiving the content bell request message, and send the selected content bell media by identifying the called terminal requested for the call. You can also select and send information.

In the present exemplary embodiment, the content bell server selects the content bell at the time of receiving the content bell request message. However, the present invention is not limited thereto and the content bell request message is transmitted from the application server or the call server to the content bell server. Of course, the content bell may be selected and implemented to send a content bell request message.

In addition, the content bell server may extract and transmit a part or all of the content bell media information to correspond to a predetermined size or a predetermined playing time among the content bell media information in consideration of the called terminal for transmitting the content bell media information. Can be. The size or the playing time can be flexibly selected by a system operator. For example, the content bell media information can be extracted in consideration of the size and the playing time that can be optimally implemented in the called terminal. have. For example, if the content bell media information is real time sound information, the content bell server extracts real time sound information corresponding to a size '100 Kbyte' or a playing time '30 seconds' that can be optimally implemented in the called terminal. Can be sent out.

In addition, the content bell server may repeatedly transmit the extracted content bell media information to the called terminal under a predetermined condition. The above condition may refer to a case in which all of the extracted content bell media information is transmitted, but continuous transmission of content bell media information is required because a transmission stop request is not transmitted from the call server / application server. That is, the content bell server may repeatedly transmit the extracted content bell media information until a transmission stop request is received from the call server / application server.

In the present exemplary embodiment, the content bell server repeatedly transmits the extracted content bell media information. However, the present invention is not limited thereto, and the content bell media information is transmitted to the called terminal and each called party sets the called terminal. The content bell media information may be extracted or repeatedly implemented according to an implementation environment.

The calling terminal is a device for transmitting a call request to the call server for a telephone call with the called terminal, and can generate a call request by, for example, inputting a telephone number for specifying the called terminal on the calling terminal.

The called terminal has the ability to implement the received content bell media information as a call signal, and by generating an incoming signal in response to the incoming call request (eg, the caller inputs a call button of the called terminal), It can form a call route of.

In addition, the called terminal may limit the media information of the content bell to be received by including the currently-implementable media attribute set by the called party in the content bell transmission request message. For example, when the called party sets the terminal to the vibrate mode, the receiver may receive content bell media information excluding sound from the content bell server by transmitting the content bell except for the sound information.

The real-time streaming on-demand bell service providing system stores the content bell media information provided by the content providing server, and transmits the content bell media information to the called terminal requested in real time by calling the content bell media information from the called terminal. To be implemented.

2 is a flowchart illustrating a method of providing a real-time streaming on-demand bell service according to the present invention in detail.

First, the real-time streaming on-demand bell service providing system transmits a call request message to the called terminal in response to the call request received from the calling terminal in the call server (S210). This step (S210) is a process of receiving a call request generated in the calling terminal at the call server, and transmitting a call request message relating to generation of a content bell request to the called terminal according to the reception of the call request. In particular, the real-time streaming on-demand bell service providing system in this step (S210) confirms whether the receiving terminal or the receiver subscribes to the content bell service of the present invention, the content bell service call request only for the called terminal or the called party that the subscription is confirmed Send a message. In addition, the real-time streaming on-demand bell service providing system determines whether the destination terminal can implement the content bell media information, and transmits the content bell service call request message only to the destination terminal that is determined to be implemented.

In addition, the real-time streaming on-demand bell service providing system in the step (S210) identifies the called terminal that the call request was made by the calling terminal, and the call server to transmit the call request with the call request message to the identified called terminal By controlling later, a call connection path is formed between the calling terminal and the called terminal.

In addition, the real-time streaming on-demand bell service providing system transmits the content bell request message to the content bell server in response to the content bell request received from the destination terminal for the call request message in the call server (S220). This step (S220) receives the content bell request from the destination terminal requesting the reception of the content bell media information to be implemented as a call signal, the content bell associated with the transmission of the content terminal media information from the content bell server in connection with the content bell server Send the request message to the content bell server.

In particular, the real-time streaming on-demand bell service providing system in this step (S220), when a content bell rejection request is received from the called terminal for the call request message, the content bell request to the content bell server in response to the content bell rejection request You can control not to send a message. For example, if the called terminal has a content bell blocking setting, the called terminal generates a content bell rejection request for blocking the implementation of the content bell and transmits it to the real-time streaming on-demand bell service providing system, or directly to a general call without a rejection request message. Can be switched to work.

Subsequently, the real-time streaming on-demand bell service providing system transmits the content bell media information to the called terminal in response to the content bell request message from the content bell server (S230). The content bell media information may include, for example, one or more of video, audio, and text formats of advertisements, news, music, images, and useful content registered in the storage device by the content providing server. That is, in particular, the real-time streaming on-demand bell service providing system in this step (S220) may extract the content bell media information from the storage device in association with a random or called terminal to repeatedly send to the called terminal.

In addition, the real-time streaming on-demand bell service providing system receives an incoming signal from the called terminal (S240). This step (S240) is a process of receiving, at the call server, an incoming signal generated when the called party inputs a call button to a called terminal embodied by the content bell media information. The incoming signal may be generated by a caller who wants to make a phone call with the caller, for example, by inputting a call button of the called terminal on which the content bell media information is implemented.

Subsequently, the real-time streaming on-demand bell service providing system transmits a request to stop content bell media information from the call server to the content bell server in response to receiving an incoming signal, and content bell media information from the content bell server according to the request to stop transmission. The sending of the called terminal is stopped (S250). This step (S250) is a process of transmitting the content bell media information, that is, the implementation of the call signal in the called terminal to stop the formation of the call connection between the calling terminal and the called terminal.

In addition, the real-time streaming on-demand bell service providing system forms a call connection path between the calling terminal and the called terminal (S260). This step (S260) is to make a telephone call between the calling terminal of the caller and the called terminal through the call server, and thus the caller and the called party can make a phone call.

Therefore, according to the present invention, the receiver terminal receiving the call request to implement the content bell media information associated with the content providing server as a call signal, so that the content bell media information is provided to the receiver terminal in various ways by the streaming method. Can be.

3 is a flowchart illustrating a schematic operation of a call server driven under the control of a system for providing a real-time streaming on-demand bell service according to the present invention.

The call server receives the call request from the calling terminal, identifies the called terminal of the call, and determines whether the identified called terminal (or subscriber) is a subscriber of the content bell service.

As a result of the determination, if the terminal (or subscriber) is not subscribed to the service, the call server proceeds with the subsequent call proceeding like a general call.

On the contrary, if the terminal is subscribed to the service, the call server transmits a content bell service call connection request to the called terminal.

Subsequently, the call server receives the content bell request message from the called terminal, and determines whether the called terminal rejects the content bell.

If the called terminal rejects the content bell request, the call server waits for a call connection response message from the called terminal as in the general call.

On the other hand, when receiving a content bell request from the called terminal, the call server sends a content bell transmission request message to the content bell server, and waits for a call connection response message from the called terminal.

Subsequently, upon receiving the call connection response message from the called terminal, the call server determines whether the content bell service is in progress, and if so, sends the content bell transmission stop request message to the content bell server.

Thereafter, the call server forms a call connection path between the calling terminal and the called terminal.

4 is a flowchart illustrating a schematic operation of a content bell server driven under the control of a system for providing a real-time streaming on-demand bell service according to the present invention.

When the content bell server receives the content bell request message from the call server, the content bell server selects the called party request content bell based on the information selected from the called terminal (or subscriber) or randomly selects the content bell.

The content bell server compares the media property of the selected content bell with the media property of the called terminal to determine whether to convert the media.

Subsequently, the content bell server converts the selected content bell when it is needed for media conversion and repeatedly sends it to the called terminal.

The sending of the content bell continues until the content bell stop request message is received from the call server.

When the content bell server receives the content bell stop request from the call server, the content bell server stops transmitting the content bell to the called terminal.

5 is a block diagram showing a system for providing real-time streaming on-demand bell service according to an embodiment of the present invention.

The real-time streaming on-demand bell service providing system 500 of the present invention may include a call server 510 and a content bell server 520.

The call server 510 transmits a call request message to the called terminal in response to the call request received from the calling terminal, and generates a content bell request message in response to the content bell request received from the called terminal in response to the call request message. . That is, the call server 510 searches for a called terminal requested by the calling terminal and transmits a call request message relating to generation of a content bell request to the found called terminal. Here, the call request message is transmitted as a content bell call message only when the called terminal or the called party subscribes to the content bell service of the present invention or when the called terminal can implement the content bell media information. A general call message may be sent to the called terminal. The called terminal receiving the content bell call request message may transmit a content bell request to the call server 510, and the call server 510 may receive a content bell request from the content bell server, and may transmit the content bell media information to the content bell server. Sends content bell request message related to transmission.

In particular, the call server 510 does not transmit the content bell request message to the content bell server 520 in response to the content bell rejection request when the content bell rejection request is received instead of the content bell request from the called terminal. can do. That is, when the content bell rejection request is generated by the called party who does not want to implement the content bell media information in the called terminal, the call server 510 transmits the content bell media information from the content bell server 520 to the called terminal. It can be prevented at the source. The content bell rejection request may be generated by setting, for example, 'content bell reception rejection' in the called terminal, and may be generated in conjunction with the call request message being transmitted to the called terminal. In addition, the content bell rejection request may be generated according to the selection of the called party while the content bell media information is driven in the called terminal. In this case, the call server 510 receiving the content bell rejection request is the content bell server 520. ), The content bell media information can be stopped immediately. In the called terminal that has generated the content bell rejection request, instead of the content bell media information, the ringtone preset by the called party may be implemented.

In addition, the call server 510 searches for a called terminal for which a call request has been made by the calling terminal, and transmits the call request to the found called terminal. In the called terminal receiving the call request, a call signal (content bell media information or a ringtone of the present invention) is implemented, and as the called party inputs a call button, the called terminal may form a call connection path with the calling terminal.

In addition, the call server 510 analyzes the call request and determines whether the called party of the received call request is a subscriber of the content bell service of the present invention. As a result of the determination, if the received call request is a call request to a non-subscriber, the call server 510 may allow, for example, a ring tone supported by the called terminal to be implemented as a call signal. In addition, if it is determined that the call request to the subscriber of the content bell service, the call server 510 transmits a call request for generating a content bell request from the called terminal to the called terminal to the content bell server 520 later in the content bell Media information can be sent out.

Subsequently, when the incoming signal (for example, generated as a call button of the called terminal is input) is received from the called terminal, the call server 510 controls the content bell server 520 to control the content bell server 520. Media information transmission can be stopped. In addition, the call server 510 forms a call connection (phone call connection) between the calling terminal and the called terminal according to the reception of the incoming signal.

The content bell server 520 transmits the content bell media information to the called terminal in response to the content bell request message generated from the call server 510. That is, the content bell server 520 includes storage means 525 for storing one or more content bell media information. When the content bell request message is received from the call server 510, the content bell server 520 stores the content in the storage means 525. The bell media information is extracted and sent to the called terminal.

In particular, the storage means 525 according to an embodiment of the present invention may store the content bell media information in association with the called terminal or the called party having a contract related to providing the content bell service. To this end, the content bell server 520 provides a content list regarding the content bell media information registered by the content providing server to the called terminal or the called party, and provides the provided content list (for example, a list sorting the names of the content bell media information). Receives a selection signal of the called terminal or called party; Thereafter, the content bell server 520 may store the content bell media information corresponding to the selection signal in the storage means 525 in association with the called terminal or the called party. Accordingly, when the content bell request is received from the call server 510, the content bell server 520 identifies the called terminal associated with the occurrence of the content bell request, and stores the content bell media information associated with the identified called terminal. It can be extracted from the means 525 and sent to the called terminal.

In addition, whenever the content bell request message is received from the call server 510, the content bell server 520 may randomly extract the content bell media information to be sent to the called terminal from the storage means 525. By the extraction method of the content bell media information, the content bell server 520 can extract all content bell media information stored at equal probability, and accordingly, the specific content bell media information is transmitted to the called terminal which is biased. Can be suppressed.

In the present specification, the content bell media information is produced by the content providing server and stored in the storage means 525, and useful content such as advertisements, news, music, movies, and the like, which are transmitted in real time to the destination terminal by a streaming method, such as video, Multimedia information that includes one or more in audio and text format. The production of the content bell media information or the content bell media information registration process to the content bell server 520 may be applicable to those that can be flexibly devised by those skilled in the art, detailed description thereof will be omitted.

Therefore, according to the present invention, the useful information transfer effect using the call signal can be obtained by implementing various content bell media information of the content providing server as the call signal at the time of the call request.
