The existing mobile communication network (PLMN) and the public switched telephone network (PSTN) provide a voice call service, and the third generation mobile communication network (BcN: Broadband Convergence Network) provides a video call service. In addition, various additional services such as 1588 main phone number, 080 toll free number, 060 phone information, and 1541 toll free number are provided through these telephone networks. The existing intelligent network service uses only the telephone network.

On the other hand, with the emergence of international standard protocols such as Parlay API, it is possible to control calls by accessing various kinds of telephone networks from the Internet. For example, in a service called Click-To-Call, when a user clicks only a phone number displayed in a web browser, a server on the Internet sets up a call between the sender and the receiver to make a call easily. .

However, despite the interworking of the telephone network and the Internet, only the telephone service is provided through the telephone network and only services such as file transmission and reception are provided through the Internet. For example, there is no differentiated service in which a telephone network and the Internet are combined in providing a voice call service.

For example, the user may not be able to change the background sound at all during a call, or even if the user may change the background sound, there is an inconvenience of having to select from the limited background sounds of about two or three songs which are specified in advance. In addition, in the prior art as described above, it is not possible to provide contents such as a video, a document, etc., which are not sound-based background sounds or sound effects during a call. As another example, even if there is a record, a movie, a voice letter of another friend, etc. that you want to show or hear to the other party during a call, it cannot be played to the other party, and it is difficult to play multiple contents during one call.

In addition, in the background sound and effect sound providing service described above, only the sound set in advance by the caller corresponding to the subscriber of the service is provided to the receiver. Therefore, the receiver cannot select or stop the background sound suitable for his or her taste and taste. The service provided is not activated.

Therefore, any caller or receiver during a call can upload or stop the multimedia content by uploading it directly to the other person in real time or by designating content on the web regardless of the kind of content that the caller or receiver wants to show or hear to the other party. There is an urgent need for a service that can simplify content playback.

The present invention has been proposed in order to solve the above problems and to meet the above requirements, and the user directly selects the contents which he / she wants to show or hear to each other during the call in real time directly through the Internet [upload or A system for providing contents according to a caller's request in real time during a call, which is designated to be reproduced on a counterpart terminal by designating contents on the web, and a computer-readable recording medium having recorded thereon a program for realizing the method.

In the present invention, regardless of the type of content that the caller or receiver wants to show or hear to the other party during a call, for example, any multimedia content can be uploaded directly in real time through the Internet or designated on the web and played back to the other party through a telephone network. Provides services that make it easy to pause, pause, or play other content.

In order to be provided with the above service, information (eg, ID, IP address, etc.) that the user, preferably the caller, can be identified in advance while the user subscribes to the service through a web page, a customer call center, etc. In addition, it is preferable to register information (for example, a telephone number, etc.) and other subscription information, etc. which can be identified by the own phone 10 with the service providing server 30. Of course, this is the case in which the caller plays the content to the receiver. On the contrary, the receiver also subscribes to the service in order for the receiver to play the content to the sender or to request the suspension of the content provided from the caller. It is desirable to.

On the other hand, in the telephone connection between the sender and the receiver, upload the content or select any one of the content list on the web page operated by the service providing server 30, or to play or stop the content, the user It is preferable that a client program equipped with such a function be installed in the computer so that the computer 20, 70 can simplify the operation. Through such a client program, the service related request / response is performed using a protocol such as HTTP or FTP between the sender side computer 20 and the service providing server 30 and the receiver side computer 70 and the service providing server 30. do.

Each of the sender side and the receiver side is provided with computers 20 and 70, which may be replaced by a corresponding terminal conforming to the protocol of the Internet as a means (Internet access terminal) for Internet access. For example, in the wired Internet, the Internet access terminal may be implemented as a personal computer (PC), and in the portable Internet, it may be implemented as a WiBro terminal, a notebook computer, a PDA, an HSDPA phone, and the like. Hereinafter, the present invention will be described by taking a computer as an example of an Internet access terminal.

The caller side and the receiver side are provided with telephones 10 and 60, which are preferably replaced by a corresponding terminal complying with the protocol of the telephone network as a means [call terminal] for a call. For example, in a PSTN, a call terminal may be implemented as a wired telephone, a mobile communication network may be implemented as a mobile phone, and in a video call network, it may be implemented as a VoIP telephone. Hereinafter, in the present invention, as a call terminal, such a phone may be a phone equipped with a display (liquid crystal) function.

In addition, a PDA phone capable of both internet access and voice call may be a means to make the use of the service more convenient since the subscriber does not have to carry an Internet access terminal and a call terminal separately for the service.

As mentioned in the description of the subscriber terminal, the Internet for this service may follow any protocol such as wired internet, mobile wireless internet, and portable internet, and the telephone network for this service is also PSTN, mobile communication network, VoIP network. , BcN, etc. may be followed. In particular, such a telephone network is linked to an intelligent network for signal processing, data conversion, call control, etc. for the present service, which is based on AIN (Advanced Intelligent Network) or IMS (IP Multimedia Subsystem).

Then, each component of the present system shown in FIG. 1 will be described in detail.

The subscriber DB 50 stores subscriber information such as personal information of the service subscriber, computer identification information (eg, subscriber ID, IP address, LAN card MAC address, etc.) and telephone identification information (eg, phone number, etc.). It is managed by the providing server 30. Such subscriber information is used as information for subscriber authentication when the service providing server 30 receives a request for providing the service from a sender or the like.

The call information DB 40 stores call information of a current call state where the service is provided and is managed by the service providing server 30. Such call information includes an outgoing telephone number, an incoming telephone number, a call state, a call ID in a telephone network, whether content is played, and a content play server ID.

The content temporary DB 80 temporarily stores the content to be played by the content playback server 110 in a call path connected between the caller-side telephone 10 and the receiver-side telephone 60. Can be uploaded to the service providing server 30 via a computer or content on the web designated by the URL presented by the subscriber (Note: the service providing server downloads the content indicated by the URL and stores it in the content temporary DB). Can be.

The service providing server 30 performs overall control of the service, and is connected to the service exchanger 100 and the content reproduction server 110 through the gateway 90 for interworking with the telephone network on the intelligent network.

The service exchanger 100 collects additional call information and functions such as signal processing, call path management, etc. so that an intelligent network service such as this service is provided to a call connected between the caller-side telephone 10 and the receiver-side telephone 60. The service providing server 30 performs a function of notifying.

The content reproduction server 110 performs a function of reproducing the content commanded from the service providing server 30 in a call path set between the caller-side telephone 10 and the receiver-side telephone 60, that is, played on the counterpart terminal. It is preferable to implement the specification according to the protocol of the telephone network. For example, in the case where the telephone network is a PSTN, the content reproduction server 110 mixes the user voice and the content (preferably audio) and provides it to a call path, and the telephone network is a VoIP network (commonly called a video call network). In the present invention, the audio content is mixed with the audio stream and the video content is mixed with the video stream between the calling party and the receiving party, and the audio content is reproduced on the call path. That is, playback is performed on the opposite terminal.

Meanwhile, the service providing server 30 performing overall control of the service will be described in more detail.

In order to perform the service, the service providing server 30 needs to obtain control of a call on a call route connected between the calling party's telephone 10 and the called party's telephone 60. There are two types of call control right acquisition methods depending on the telephone connection method between subscribers.

In the first method, when a caller makes a call to his / her telephone 10 directly on his / her telephone 10, the caller's call is triggered as in the general intelligent network call processing procedure, and the service providing server 30 is provided through the service switch 100 on the telephone network. ) Control is taken over the call. Accordingly, the service providing server 30 performs the service processing procedure in the state in which the information on the call between the caller-side telephone 10 and the callee-side telephone 60 is stored in the call information DB 50. This triggers a call originating from the telephone network and passes the call control right to the service providing server 30 on the service network.

In the second method, the caller connects to the service providing server 30 through a client program installed in his computer 20 and requests a telephone connection. Such a call connection request message includes an outgoing call number, an incoming call number and computer identification information. Therefore, when the service providing server 30 receives the call connection request, after the subscriber authentication is performed based on the subscriber information stored in the subscriber DB 50, the caller side telephone 10 is transmitted to the service exchanger 100 on the telephone network through the gateway 90. And open the call path between the receiver 60 and the telephone. Accordingly, when the call path between the calling party's telephone 10 and the called party's telephone 60 is opened by the service exchanger 100, the service providing server 30 stores information about the call in the call information DB 50. This service process is performed in the state. This means that the service providing server 30 on the service network starts a call from the beginning and has the call control right.

In addition, the service providing server 30 processes the content playback request received from the subscriber computer. The content reproduction request message includes the subscriber's telephone number, computer identification information, and the content itself (file upload) or a URL indicating the content location (content location information selected by the subscriber on the web).

In the case of receiving the content reproduction request from the subscriber as described above, the service providing server 30 after the subscriber authentication based on the subscriber information stored in the subscriber DB 50 [Note; If the call is requested from the caller and the call is opened, it is not necessary to separately authenticate the content playback request.], The call information corresponding to the corresponding phone number stored in the call information DB 40 is obtained. Based on this, the content is played on the corresponding channel.

On the other hand, the type of content requested to be reproduced by the subscriber may be multimedia data in various formats such as voice, video, text, and PDF document. The various types of formats should be able to be reproduced in a call path, and the service providing server 30 performs a function such as proper format conversion according to the call path protocol.

For example, if the call path between the calling party's telephone 10 and the called party's telephone 60 belongs to the PSTN, the service providing server 30 extracts only text from the PDF document when receiving a request for providing a PDF document from the subscriber. (TTS) to convert the audio content. The audio content converted in this way is stored in the content temporary DB (80), the content playback server 110 receives a content playback command from the service providing server 30, the user retrieves the audio content from the content temporary DB (80) It mixes voice and audio content and provides it to the channel. In addition, the content reproduced by the content reproduction server 110 is preferably deleted from the content temporary DB (80).

In addition, the service providing server 30 processes the content playback stop request received from the subscriber computer. The content reproduction stop request message includes a subscriber's telephone number and computer identification information, and content information to be played back is not necessarily required. For example, the service providing server 30 issues a content playing stop command to the content playing server 110 playing the content on the corresponding call path based on the call information DB 40.

The service processing flow performed in the present system as described above will now be described with reference to FIG.

2 is a flowchart illustrating a method of providing content according to a caller's request in real time during a call according to the present invention.

First, a call path between the caller side telephone 10 and the receiver side telephone 60 is connected (set up) (201). Here, in the call path connection method, as described with reference to FIG. 1, a caller makes a call by directly calling his / her telephone 10 to the receiver side phone 60, and a call path is set accordingly. The control of the call is passed to the service providing server 30 through the service switch 100 (202). In FIG. 2, the first call setting method will be described as an example.

Then, the service providing server 30 stores the call information set between the caller-side telephone 10 and the receiver-side telephone 60 in the call information DB 40 based on the obtained call control right (203), and the present service. Perform the process.

On the other hand, the call path setting method according to another embodiment, as described with reference to Figure 1, the caller is connected to the service providing server 30 through its computer 20 to request a telephone connection, the service providing server After the subscriber 30 authenticates the subscriber, the call switch between the caller side telephone 10 and the receiver side telephone 60 is established by the service switchboard 100. Here, the service providing server 30 obtains this call control right in accordance with the telephone connection request processing.

In the state in which the service providing server 30 obtained the call control right as above [Note; Of course, at this time, a call is started between the caller and the receiver]. If the service providing server 30 receives the content play request message from the subscriber (sender or caller) computer (204), the content play request message is included. Information is compared with the subscriber information stored in the subscriber DB 50 to authenticate the subscriber, for example, to accept a content playback request (205). Here, the content reproduction request message includes the subscriber's telephone number and the computer identification information, as well as the content itself (file upload) or a URL (content location information selected by the subscriber on the web) indicating the content location.

Upon successful subscriber authentication [consent content playback request] as above, the service providing server 30 obtains the call information corresponding to the subscriber's telephone number from the call information DB 40 and based on this, the process as follows. Allow content to be played on the channel.

That is, the service providing server 30 may receive a multimedia content reproduction request from a subscriber in various formats, and the reproduction request content may be reproduced in a call path set between the caller-side telephone 10 and the receiver-side telephone 60. The conversion is performed to the content and stored in the content temporary DB 80 (206). At this time, if the service providing server 30 inquires the call information obtained from the call information DB 40, the content playback is stopped if the content is already being played on the corresponding channel by the content playing server 110. Afterwards, it is preferable to load the uploaded content included in the content reproduction request message or the content indicated by the URL to perform a content conversion process.

For example, if the call path between the calling party's telephone 10 and the called party's telephone 60 belongs to the PSTN, the service providing server 30 extracts only text from the PDF document when receiving a request for providing a PDF document from the subscriber. (TTS) to convert the audio content. The audio content converted as described above is stored in the content temporary DB 80.

Then, the service providing server 30 issues a content playback command to the content playback server 110, accordingly the content playback server 110 retrieves the corresponding content stored in the content temporary DB (80) and the caller Playback is made in the call path set between the telephone set 10 and the telephone set 60 (207). For example, the content playback server 110 receiving the content playback command from the service providing server 30 retrieves the corresponding audio content from the content temporary DB 80 and mixes the user's voice and audio content to the call path on the PSTN. Play it.

As described above, when the caller and the receiver share the multimedia content with each other with a call and receive a content stop request message (or other content play request message) from the subscriber (sender or receiver) computer, If you are an unauthenticated subscriber (e.g., if the recipient requested to stop playing the content while it was being requested by the sender), make sure that the content playback is stopped by performing the subscriber authentication process. In the case of an authenticated subscriber, playback of the content is stopped without performing a separate subscriber authentication process.

In the above-described service, any caller or receiver can make a content play request, a content play stop request, another content play request, and the like easily through their own computer regardless of the number of times during the call.

As described above, the method of the present invention may be implemented as a program and stored in a recording medium (CD-ROM, RAM, ROM, floppy disk, hard disk, magneto-optical disk, etc.) in a computer-readable form. Since this process can be easily implemented by those skilled in the art will not be described in detail any more.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

In the present invention as described above, regardless of the type of content that the caller or the receiver wants to show or hear to the other party, for example, any multimedia content is directly uploaded in real time or selected on the web and played to the other party, There is an effect that can easily stop, play other content.

In addition, the present invention can create a more intimate feeling by sharing the content that matches the hobbies and preferences with the other party during the call from the user's point of view, and the service provider separately to the audio data, video data, etc. on the server for each subscriber There is an effect that the service can be operated inexpensively because it does not have to be stored.
