Description

Apparatus and method providing functions to scrap video information provided on a videophone screen during a call, and a method thereof, and a method thereof additional service system and method using its}

The present invention relates to an apparatus and method for scraping video information provided on a video telephone screen during a call, and an additional service system and method using the same. More specifically, a video telephone user can make a voice call with a voice-only telephone user. The present invention relates to a video information scrap service apparatus and a method for scraping video information (including subtitle information) provided as a substitute video during a voice call.

In addition, the present invention, when the video telephone user makes a video call with the video telephone user, it is possible to scrape the caption information provided with the counterpart image during the video call.

In addition, the present invention is to enable the additional services (e.g., replay, view detailed information, telephone connection, etc.) by accessing the information (video information / subtitle information) scraped during the voice or video call after the call ends .

In the present invention, 'video information that is subject to scrap' is video information that can be viewed while making a voice call with the other party when the video telephone user calls with a voice-only telephone user.

In addition, in the present invention, the "subtitle information to be scraped" is subtitle information that can be seen while making a video call with a counterpart when a video telephone user makes a video call with another video telephone user.

In addition, in the present invention, the 'video information / subtitle information to be scraped', the video information / subtitle information provided according to the user's taste (call type, customized, broadcast type, location-based, etc.) during the voice call or video call to be.

In the above, the video information (possibly including subtitle information) to be scraped is transmitted to the video telephone of one side during the voice call. Correspondingly, 'voice-only telephone' on the other side of the video telephone (one IP-based video telephone (multimedia terminal or video terminal) to be used in Internet or Broadband convergence network (BcN) environment) on one side Can be used for voice only (eg, 2G mobile terminals, public switch telephone network (PSTN) voice phones, etc.), or 'no voice support because the phone user does not want a video call. Voice call telephone (eg, SIP / H.323 / H.324 videophone, 3G mobile communication terminal, etc.).

In addition, 'subtitle information to be scraped' is transmitted to the video telephone of one side during the video call. Correspondingly, the 'video phone' on the other side of the call with the video phone on one side also supports the video and is set to the video mode (for example, SIP / H.323 / H.324 video phone, 3G mobile communication terminal, etc.). ) It is a video phone.

In addition, the form of providing 'video information' provided during a voice call may be provided as pure video information without sound due to the nature of a company advertisement / promotion and other information (life, region, hobby, news, weather, etc.) or a subtitle. Can be provided with information. In addition, in the form of 'subtitle information' provided during a video call, corporate advertisement / promotion and other information (life, region, hobby, news, weather, etc.) are provided as subtitle information.

Here, the pure video information is preferably provided to the video telephone during the voice call during the video telephone and the voice-only telephone period. However, it is desirable that the caption information is provided to the video phone together with the other party's video when the video call is made during the video call and the video call, or to the video phone when the video call is made during the video call and the voice-only call. Do. In particular, pure image information and subtitle information can provide location-based information.

Here, as the content type of 'video information / subtitle information,' call type video information / subtitle information provided by the other party on the call, its attributes (eg, home, SOHO) and time (eg, morning, evening , Festivals, admissions, graduation, etc.), or personalized video / subtitle information provided by selecting interests (e.g., life, region, hobbies, etc.) For example, broadcasting type image information / subtitle information provided to a user, location-based image information / caption information providing a location-based local advertisement / promotion, and the like. However, the location-based image information / subtitle information may be provided with broadcast type image information / caption information, call type image information / caption information, and customized image information / caption information. That is, for example, location-based video information / subtitle information may be location-based broadcast type video information / caption information, location-based call type video information / caption information, location-based customized video information / caption information.

Hereinafter, in the case where the image information and the subtitle information are not separately distinguished, the image information should be interpreted as a concept including pure image information and subtitle information.

Hereinafter, a video telephony service will be described mainly as a prior art of the present invention.

While voice-based services have been provided in conventional telephone networks (PSTNs) and mobile communication networks, IP-based video phones, video call phones, etc., which have been widely used in recent years, are multimedia services including video and data as well as voice. to provide.

Unlike the voice telephony service, the video telephony service can provide video information on the screen. The characteristics of the video telephony service have a great expectation in terms of utilization, scalability, and communication.

In general, a video telephony service exchanges video / audio codecs and channel information such as IP (Internet Protocol) addresses and ports during a connection. After the call connection process is completed, a call is made by transmitting a video / audio media packet to a channel of the other party. This process will be described in more detail with reference to FIGS. 1 to 3 below.

1 shows a case where the calling party is a video phone, and FIG. 2 shows a case where the called party is a video phone. 3 shows a video call procedure when both sides are video phones.

As shown in Fig. 1, when the calling party is the video phone A and the called party is the voice-only phone B, the video phone A uses the soft switch (SSW) to convert its voice channel and video channel information to the call connection request. To the voice-only phone B. Since the voice-only phone B does not support video, only the voice channel information is answered to the video phone A through the soft switch (SSW) when the call connection request is accepted. Only voice calls are made between them.

On the other hand, as shown in Fig. 2, when the calling party is a voice-only phone A and the called party is a video phone B, since the voice-only phone A does not support video, only the voice channel information of the user is soft when the call is requested. It sends the video phone B through the switch (SSW), and when the video phone B accepts the call connection request, it responds to the voice-only phone A through the soft switch (SSW). Only voice calls are made between incoming and outgoing phones.

In this case, when the called party is a video phone, there is no video channel information when a call is requested from the calling party. Even though the called party supports video, the called party includes video information when responding to a call request (accepting a call connection request). You may not. This is shown in parentheses for the image information.

1 and 2, the voice-only phone corresponds to a PSTN phone / 2G mobile communication terminal. However, since the PSTN telephone / 2G mobile communication terminal cannot be directly connected to the IP network, it is necessary to use a gateway that mediates the connection with the IP network. Therefore, in FIG. 1 and FIG. 2, when the voice-only telephone is a PSTN telephone / 2G mobile communication terminal, it has a configuration including a gateway for interfacing with an IP network.

In the current video telephony service, since video telephony has not yet been widely used, even when using a video telephony, as described in FIGS. 1 and 2, a voice-only telephone such as a PSTN telephone / 2G mobile communication terminal can only talk with a voice-only telephone. There are many cases.

However, there is a problem that the screen display device of the video telephone is not used during the call when the phone is connected to the voice-only phone that supports only the voice. Of course, the video phone itself performs an operation such as showing the user's screen during a voice call, but this is only a method of temporarily filling the screen, and is not a method of fully utilizing the video phone as a multimedia medium. Therefore, according to the configuration of Figures 1 and 2, not only the video call advertising service is possible, but also additional services (for example, view again, view detailed information, telephone connection, etc.) using the same.

On the other hand, as shown in Fig. 3, the basic video telephony service uses a terminal-to-terminal connection method focused on the concept of a call service.

As shown in Fig. 3, when the calling party and the called party are video phones, the calling party video phone A receives the video channel information of the called party through the soft switch (SSW) when the call connection request is made. In response, the called party's video phone B responds to the calling party's video phone A through the soft switch (SSW) when receiving the call connection request. Video call is made.

In FIG. 3, the video phone corresponds to a SIP / H.323 / H.324 video phone and a 3G mobile communication terminal.

However, in FIG. 3, since the video channel and the audio channel are made between the outgoing video phone A and the incoming video phone B, the service can be expanded in such a manner as to provide various contents by intervening with a third device. none.

That is, as mentioned in FIG. 3, when the video phone service is configured only by connecting the video / audio channel with one counterpart phone simultaneously, the video phone service can be separated from the video channel and the audio channel. It becomes difficult to create various value-added / application services. Therefore, according to the configuration of FIG. 3, not only the video call advertisement service is possible, but also additional services using the same (eg, replay, detailed information view, and telephone connection) are also impossible.

On the other hand, the voice call advertising service in the existing PSTN, etc. in advance in the form of voice announcements in advance causes inconvenience to users and has a problem that the user should spend a separate time. In addition, the provided advertisement does not reflect the user's taste and provides the advertisement indiscriminately. Therefore, there is a limitation in implementing a video call advertising service by introducing a voice call advertising service to a video phone service.

Therefore, there is an urgent need for a new video call advertising service plan suitable for video telephony services. Therefore, it would be more useful for the video telephony service if it could reflect the characteristics of the video telephony (using the screen display device of the video telephony not used during the voice call) and simultaneously provide useful information or advertisements while making a voice or video call. It is expected. In addition, by providing video information suitable for users' tastes (call type, customized, broadcast type, location-based type, etc.) during a voice or video call, it enhances the satisfaction of the video phone user and the utilization of the video phone, and expands the use of information contents. It is expected to generate various profits by expanding the advertising market.

In particular, the video information (possibly including subtitle information) provided as a substitute video during a voice call can be scrapped during a voice call (video information scrap service function), and the subtitle provided with the other party's video during a video call. Provides the ability to scrap information during a video call (caption information scrap service function) and after the call ends the scraped information (video information / subtitle information) during a voice or video call through the video information / subtitle information scrap service function. If you can access additional services (e.g., replays, view detailed information, telephone connections, etc.) by accessing it, it is expected that you will be able to create secondary revenue sources such as information usage fee, shopping mall connection, and agent connection.

Accordingly, the present invention provides a video information scrap service apparatus and a video information service for enabling a video telephone user to scrap video information (including subtitle information) provided as a substitute video during a voice call when making a voice call with a voice-only telephone user. The purpose is to provide a method.

The present invention also provides a caption information scrap service apparatus and method for enabling a video telephone user to scrape caption information provided with a counterpart image during a video call when making a video call with the video phone user. There is a purpose.

In this case, the location-based subtitle information may be provided with broadcast subtitle information, call type subtitle information, and customized subtitle information. For example, location-based subtitle information, location-based call subtitle information, location-based custom caption. Caption information is available. However, as described above, the caption information may be provided together with the pure video information during a voice call, or may be provided together with the counterpart video during a video call.

As such, the effect of the video information (/ subtitle information) provided to the video phone 30 is to provide the video information (/ subtitle information) according to the user's taste, thereby increasing the satisfaction of the video phone users and the utilization of the video phone, the information It is possible to generate various profits by expanding content usage and expanding the advertising market.

In order to provide such video information (/ subtitle information), the video information service device 10 must be implemented by using a Session Initiation Protocol (SIP) used as a communication means signaling protocol in an IP network. Servers (eg, video information management server 12, application server 11, media server 13, location information management server 15, etc.) and element descriptions within the server.

That is, for the telephone service in the IP-based network of the Internet and BcN, there must be a soft switch 20 corresponding to the switch 50, 70 of the CDMA mobile communication network, the telephone network (PSTN). The soft switch 20 connects a video call to an IP network such as BcN or the Internet. In other words, Voice over Internet Protocol (VoIP) video telephony uses an IP network to transmit video information. In a packet-based IP network, call routing is required for telephony services. Use In addition to basic call routing, an application server 11, a media server 13, and the like are required to control application services. At this time, the application server 11 manages the information of the subscribers and determines what video information to send to the media server 13, the media server 13 is a video session (video channel) with the video telephone 30 Open and sends the video information to the video phone (30). In order to provide the image information in such a structure, an image information management server 12 for uploading and managing content and a content DB 14 for storing image information are required. In this case, various image information is stored in the content DB 14, and the image information management server 12 manages the content DB 14 and transmits the corresponding image information to the application server 11.

Application services related to the video call should be linked with the soft switch 20, and the video information service device 10 should be linked with the application services. Therefore, in the video information service apparatus 10, a logic or a function necessary for providing video information should be added to the application server 11 that controls application services, manages subscriber information, and provides some video information to the media server 13. It decides whether to send. In addition, in the video information service apparatus 10, the media server 13 opens a video session with the video telephone 30 and transmits the video information to the video telephone 30. In this case, the media server 13 is normally provided. The function of extracting and transmitting only the video portion from the audio / video media should be added. In addition, the image information service device 10 requires a separate server, which manages the content DB 14 that stores the image information, and the image information that manages the content DB 14 and delivers the image information to the application server 11. A management server 12 and a location information management server 15 for a location-based video information service (eg, a location-based broadcast video information service, a location-based customized video information service, and a location-based call video information service). Is an example.

As described above, the video information service apparatus 10 includes an application server 11, a video information management server 12, a media server 13, a content DB 14, a location information management server 15, and the like. They provide the image information to the user (subscriber) through the interworking (in this case, can provide the location-based image information). Referring to this, a signal is transmitted from the video phone 30 to the soft switch 20 through the SIP, and the soft switch 20 transmits the video information to the application server 11 when the condition is met (for example, a service subscriber). The SIP message informs you that it should be provided. Thereafter, the application server 11 determines what image information to provide and delivers it to the media server 13, and the media server 13 transmits the corresponding image information (call-type image information and customized image) from the content DB 14. Information, broadcast video information, location-based video information, etc.), and forms and transmits a real-time transmission protocol (RTP) channel with the video telephone 30. In this case, the media server 13 may also provide caption information when providing image information. Here, the caption information is provided together with the pure video information provided to the video phone 30 of one side during the voice call between the caller / incoming phone, or provided to the video phone 30 of both sides during the video call between the caller / incoming phone It may be provided along with the counterpart image. In this case, the caption information may be separately allocated to the data channel and synthesized by the video phone 30 to the other party's video, or the media server 13 may insert the caption information into the video information.

Here, the soft switch 20 corresponding to the exchange on the IP domain checks a specific field (eg, SIP video terminal identification number (phone number)) of the packet (eg, an INVITE message defined in SIP) (number translation). Function), a video information service subscriber (caller / receiver capable) transfers the call to the application server 11 (call processing of SIP). In addition, the application server 11 defines the type of video information (call type, personalized type, broadcast type, location based type, etc.) to be provided for each subscriber. There is a function to control their call [call control]. In addition, the media server 13 should be able to play a video session by opening a video session with the video telephone 30 (replaying various video information in a stream form). In addition, the video information management server 12 should be able to update and manage the content DB 14 and deliver necessary video information to the application server 11.

As such, the video information service apparatus 10 for the video information service function utilizes the screen of the video telephone 30 when making a voice call or a video call through the video telephone 30, which is advantageous to a video telephone user during a call.

Information (/ caption information), broadcast type video information (/ caption information), location-based call type video information (/ caption information), location-based customized video information (/ caption information), location-based broadcast type video information ( / Subtitle information)], a content DB calling unit 132 for reading out, a media player 133 for playing the video information / subtitle information read out from the content DB 14, and several media channels (video channels). , An RTP channel management logic unit 134 for managing a voice channel), and a VoiceXML interpreter 135 for reproducing a menu-selectable scrap image information / subtitle information screen.

In addition, the image information management server 12 stores user-specific scrap DB 125 that stores scraped video information / subtitle information (ie, scrap video information / scrap caption information) for each user, and an account or information of an advertisement provider. The video information provider management logic unit 121 for management, the program organization management unit 122 for organizing the video information providing program regarding the type, time and content type of the video information, and the content DB 14, The content DB control unit 123 for recording and deleting the video information, the linking unit 124 for transmitting the configuration of the video information or the new video information to the application server 11, and the video information scraped during the call Menu screen generation unit 126 for configuring a menu selection screen (menu selection scrap image information / subtitle information screen) of the subtitle information and a scenario for the scraped menu service. New scenario providing unit 127 is included.

The content DB 14 is provided based on the form of providing the video information (pure video information, subtitle information) and the content type (call-type video information / subtitle information, customized video information / subtitle information, broadcast type video information / subtitle information, location-based It is for storing video information / subtitle information by call type video information / subtitle information, location-based customized video information / subtitle information, location-based broadcasting type video information / subtitle information, and in the form of Network Attached Storage (NAS). It may be configured or implemented as a component of the media server 13.

In particular, the following process is involved for the additional service function [third embodiment].

First, when the video telephone 30, which is the main subject of the scrap, presses an automatic connection or a specific access code according to a setting to view the scraped video information / subtitle information after the call, the INVITE message from the video telephone 30 to the soft switch 20 toward the soft switch 20. The soft switch 20 transmits the INVITE message to the application server 11 by recognizing the subscriber's connection request to the scrap image information / subtitle information through the service code in the message.

Thereafter, the application server 11 carries the VoiceXML document URL in the INFO message and transmits it to the media server 13.

Therefore, when the INFO message is received from the application server 11, the media server 13 extracts the VoiceXML document URL information from the INFO message, and uses the HTTP to execute the service script to display the VoiceXML document URL using the image information management server ( Subtitle information management server 12). That is, an HTTP request message is created with the VoiceXML document URL value and transmitted to the video information management server (subtitle information management server) 12 to request the VoiceXML document.

Then, when a VoiceXML document, which is a service script, is received in response to the HTTP request message from the video information management server (subtitle information management server) 12, the media server 13 generates the parsing, interpreted, and executed voice Voice document. Image files (menu-selected scrap image information / subtitle information screen) and sound source files are transmitted to the video phone 30 through a real-time transmission protocol (RTP).

Then, when the menu-selected scrap image information / subtitle information screen and the announcement broadcast transmitted through the real-time transmission protocol (RTP) are delivered to the user (sender), the media server 13 transmits the caller and the image information management server (subtitle information). The interaction between the management server 12 is relayed. That is, the menu-selectable scrap image information / subtitle information screen reproduced by the video telephone 30 through the real time transmission protocol (RTP) [for example, '1. Car advertising ',' 2. Chicken advertising ',' 3. Through the scrap list of movie advertisements] and announcements, when a user (sender) who wants to use the supplementary service sees a menu image and presses a menu number [for example, in the scrap list, the " 1. Car advertisement '], and the media server 13 receiving the menu number through the real-time transmission protocol (RTP) displays the menu number of the additional service that the caller wants through the DTMF signal extraction process through the VoiceXML script interaction process. The information management server (subtitle information management server) 12, and the video information management server (subtitle information management server) 12 to the menu number determined by the caller, re-view function, detailed information view function, telephone connection Corresponding VoiceXML document for function [For example, if No. 1 is selected, the submenu as' 1. Watch again ',' 2. Detailed description (price, etc.) ',' 3. Menu selection screen, such as 'calling counseling call'] to the media server 13 through the HTTP protocol, and the media server 13 interprets the VoiceXML document to display the menu-selected scrap image information / subtitle information screen and the sound source file. Transfer to 30.

Such a relay process is performed by the caller pressing a menu number (for example, replay selection, detail view selection, and telephone connection selection) at which the menu selection scrap image information / subtitle information screen selection process can be terminated. It is repeated until the final VoiceXML document is received from the management server (12). In other words, if the final VoiceXML document is not received, the step continues to receive the menu number from the sender. This assumes that the replay feature, the details view feature, and in particular the telephony feature, are in the final VoiceXML document (submenu).

If the caller presses a menu number (for example, selecting to make a phone call) where the menu selection type scrap image information / subtitle information screen selection process can be terminated, the media server 13 connects the incoming call of the corresponding VoiceXML document. The telephone number is obtained from the video information management server (subtitle information management server) 12, and a session control request message to which the incoming connection telephone number is added is sent to the application server 11. The application server 11 which receives this sends the session start request message (INVITE message) to the telephones (called telephones) 30, 60 and 80 of the final destination via the soft switch 20.

Subsequently, the destination telephones 30, 60, and 60 transmit a session start in progress message (180 ring message) to the application server 11 through the soft switch 20 for the session start request message (INVITE message). When the called party (eg, an agent) receives a call (hook-off) and responds, a session start response message (200 OK message) is transmitted to the application server 11 via the soft switch 20. .

Next, when the application server 11 receiving the session start response message (200 OK message) transmits the session start re-request message (RE-INVITE message) to the caller's video telephone 30 through the soft switch 20, The session start response message (200 OK message) is transmitted from the caller's video telephone 30 to the application server 11 through the soft switch 20.

Therefore, the application server 11 sends a session start acknowledgment message (ACK message) to the session start response message (200 OK message) from the caller video phone 30 via the soft switch 20 and the caller's video phone 30. ), And a session start acknowledgment message (ACK message) is transmitted to the called phones 30, 60, and 80 via the soft switch 20 for the session start response message (200 OK message) of the called phone.

Through this process, a direct call connection is made between a called party and a called party through a real-time transmission protocol (RTP).

Hereinafter, the video information / subtitle information service function [first embodiment], which is a prerequisite for the video information / subtitle information scrap service function [second embodiment] and the additional service function [third embodiment], will be described in detail. Next, the image information / subtitle information scrap service function [second embodiment] and the additional service function [third embodiment] will be described.

6 is a diagram illustrating an embodiment of a video call path and a voice call path used in the present invention.

As shown in FIG. 6, the video call path (video channel) of the video phone 30 is generated between the video phone 30 and the media server 12 in the IP network, and the voice call path of the video phone 30 ( The voice channel is generated between the video phone 30 and the voice-only phone (eg, PSTN phone, 2G / 3G mobile communication terminal, video phone) 30, 60, 80 through the gateway 40.

In particular, in the present invention, in the video telephone service environment, the video call path (video channel) and the voice call path (voice channel) are each made through independent channels, for example, data channels and voice channels, respectively. In a video call, the user may provide video information before, during or after a call.

'Video Information Service' can be used by selecting the video information suitable for one's taste (call type, customized type, broadcasting type, location based type etc.) after proper subscription procedure according to the server's connection guide through wired / wireless internet access or ARS. have.

'Call image information [see FIG. 12C]' is provided to the other party on the call. When the service subscriber selects the call type video information, the service subscriber can select a still image or a video to be provided during the call. The video information is provided to the other party (the called party's phone when the service subscriber is the caller and the calling party's phone when the service subscriber is the called party) during the call. As a call type video information subscriber, it can be used in a place where video information can be provided instead of a caller's / caller's video screen, such as a corporate call center, a telephone room business, or an in-house telephone. In this case, the calling / receiving terminal of the service subscriber may not necessarily be the video telephone 30. However, the called / outgoing terminal on the other side must be a video phone 30 so that the call-type video information service is possible.

However, customized video information [see FIG. 12B], broadcast video information [see FIG. 12A], location-based video information (eg, location-based broadcast video information, location-based customized video information, location-based call type) Video information) (see Fig. 12D), the service subscriber does not need to select the video. However, in the case of customized image information (see FIG. 12B), one's own attributes (eg, home, SOHO) and time (eg, morning, evening, holiday, entrance, graduation, etc.) or interests (eg, life , Region, hobbies, etc.), the image information is provided to the service subscriber during the call. In addition, when the service subscriber selects the broadcast type image information (see FIG. 12A), the same advertisement / promotion is provided to the same service subscribers similarly to the TV broadcast advertisement / promotion. In addition, when the service subscriber selects location-based image information (see FIG. 12D), location-based local advertisement / promotion is provided. At this time, the location of the subscriber (for example, the same unit) is determined based on the telephone number and the IP address of the video telephone 30.

On the other hand, the service setting time can also be arbitrarily designated / released by the service subscriber, and in particular, the method for serving video information in the present invention can be provided by changing the Session Description Protocol (SDP) information, the method for transmitting subtitle information below It is assumed that the method of using the "INFO" message of the SIP, but can be replaced in other ways, such as "NETANN".

12A to 12D are diagrams illustrating an embodiment of content types of video information according to the present invention. FIG. 12A shows a broadcast type video information screen, and FIG. 12B shows a customized video information screen. 12C shows a call-type video information screen, and FIG. 12D shows a location-based video information screen (for example, a location-based broadcast video information screen, a location-based customized video information screen, and a location-based call video information). Each of which may be a screen).

The broadcast type video information shown in FIG. 12A is provided to the service subscriber's video phone 30 as a variety of beneficial advertisements, similar to a broadcast advertisement, when a subscriber who has agreed to the 'broadcast video information service' is in a voice call. In providing such broadcast type video information (hereinafter referred to as pure video information by distinguishing it from subtitle information), real-time news not related to the pure video information being provided (for example, '00 per 17th election result 00 And subtitle information such as "power-up". However, the caption information may be composed of contents related to pure image information. In addition, as described above, the caption information may be provided together with the counterpart image during the video call.

Such broadcast type video information provides subscribers with benefits such as discounts as well as substantial advertisements, and the advertisement provider has the advantage of providing various advertisements / publicity to subscribers of the broadcast type video information service.

The personalized video information shown in FIG. 12B is provided as an advertisement for a 'movie' of interest to the service subscriber's video phone 30 when the subscriber who has agreed to the 'custom video information service' is on the voice call. In providing such customized image information, for example, subtitle information, such as 'appearance of singer chant drama', which is not related to pure image information provided, may be provided together. In this case, the caption information may be composed of contents related to the pure video information, or may be provided together with the counterpart video during the video call.

Such customized video information allows subscribers to obtain information about their interests during voice calls, and the advertising provider has the advantage of providing various advertisements / promotions to the customized video information subscribers.

The call-type video information shown in FIG. 12C is applicable to a business operator or an individual using a voice-only terminal (video phone, 2G / 3G mobile communication terminal, PSTN phone, etc.) 30, 60, 80, and the like. If the phone of the calling party or the called party receiving the call supports video, the subscriber of the calling type ('calling type' It can provide the video phone 30 with subtitle information ('new product insurance', etc.) related to pure video information together with video information provided by service subscribers agreeing to 'video information service'. have. In this case, subtitle information irrelevant to the pure video information may be provided together. In addition, the caption information may be provided together with the counterpart image during the video call.

In the case of the call-type video information, the subscriber of the call-type video information has an advantage of advertising the video information that he / she wants to provide to the caller / receiver.

The location-based video information (which can be location-based broadcast video information, location-based customized video information, and location-based call-type video information) shown in FIG. 12D agrees to the location-based video information service. When a subscriber makes a voice call, the service subscriber's video telephone 30 is provided as an advertisement for 'local information (eg, chicken house)' based on the subscriber's location. Even in providing the location-based video information, it is possible to provide subtitle information ('new product olive oil chicken promotion', etc.) related to the pure video information provided to the video subscriber (30) of the service subscriber. In this case, subtitle information irrelevant to the pure video information may be provided together. In addition, the caption information may be provided together with the counterpart image during the video call.

Such location-based video information (e.g., location-based broadcast video information, location-based customized video information, location-based call-type video information, etc.) provides subscribers with local life information based on their location. It can be obtained, and provides the subscriber with benefits such as a discount rate as well as the actual advertisement provided, the advertisement provider has the advantage of providing a variety of location-based advertising / publicity to the location-based image information subscribers.

On the other hand, when a call is made between subscribers who subscribe to heterogeneous services such as 'call-type video information service' and 'custom video information service' (or 'broadcast video information service' or 'location-based video information service'). The problem of service conflicts can occur. In this case, priority may be given to the service method set by the calling subscriber, or the video information may be provided according to a policy (prior agreement) when the service is subscribed. For example, if you agree to the 'custom video information service' when you subscribe to the service, but you agree to receive 'call video information service' when you make a voice call with the subscriber of the video service, Is provided with the call type video information during a voice call with the call type video information service subscriber.

Of course, when a call is made between the same type of service or a heterogeneous service among 'customized video information service', 'broadcast video information service', and 'location-based video information service', the video is set in the manner set by each service subscriber. You just need to provide information.

In addition, when a call is made between service subscribers subscribed to the 'call-type video information service', the video information set by the other party's service subscriber may be provided.

In the above, since the 'call type video information service' is to provide video information set by the service subscriber to the counterpart, it may be considered to provide the counterpart's consent.

In particular, the location-based video information may be provided with broadcast video information, call video information, and customized video information. For example, location-based broadcast video information, location-based call video information, and location-based customization. Image information is possible.

As such, a voice channel is connected between the video phone 30 and the voice-only phones 30, 60, and 80 during a voice call, so that the video phone 30 can include video information (including subtitle information) or location-based video information (subtitle information). Or video channels are connected between the video phone 30 and the video phones 30 and 60 during a video call, and provide the video phone 30 with subtitle information or location-based caption information along with the other party's video. [See FIGS. 12A-12D].

Accordingly, the video information / subtitle information is sequentially displayed on the screen of the video telephone 30 (assuming that the video information 15a, 15b, and 15c are sequentially shown in FIG. 15), and the user is provided during the call. When the scrap input signal is pressed to scrape the video information / advertisement information (in FIG. 15, the video information 15c is selected), the video information / subtitle information is based on the telephone number (or IP address) of the video phone 30. The user is stored in the user-specific scrap DB (125) of the subscriber.

Thereafter, when the video telephone 30 ends the call and the user presses an automatic connection or a specific access code according to the setting to view the scraped video information / subtitle information, the menu-selectable scrap video information / subtitle information screen [for example, ' One. Car advertising ',' 2. Chicken advertising ',' 3. [Scrap list of movie advertisement]] 15d is displayed on the screen of the video telephone 30, and a user (sender) who wants to use the additional service presses the menu number while viewing the menu image [for example, ' One. Car advertisement '], the additional service usage screen of the corresponding video information / subtitle information (for example, if the first option is selected, the sub menu is' 1. Watch again ',' 2. Detailed description (price, etc.) ',' 3. Menu selection screen, such as 'consulting telephone call'] is displayed on the screen of the video telephone 30.

Thereafter, the user can use a desired additional service (eg, view again, view detailed information, call connection, etc.) on the additional service screen.

First, an image information service process [first embodiment] for an image information scrap service and an additional service according to the present invention will be described in detail with reference to FIGS. 7 to 10.

In the first embodiment [video information / subtitle information service function], pure video information [eg, broadcast type video information, customized video information, location-based video information (location-based broadcast type) to a video telephone of a calling subscriber during a voice call. Image information, location-based customized image information), etc.] [subtitle information can be included when providing pure image information] [see FIG. 7]. In addition, pure video information [eg, broadcast type video information, customized video information, location-based video information (location-based broadcast video information, location-based customized video information) to the video subscriber 30 of the called subscriber during a voice call. Etc.] [subtitle information can be included when providing pure video information] [see FIG. 8].

In Figs. 7 and 8, the other party's telephones (incoming or outgoing terminals) 30, 60, and 80 that make voice calls with the subscriber video telephone (originating or terminating terminal) 30 on one side are sufficient as voice dedicated telephones.

Of course, as described above, there may be a case where both the caller and the called party are subscribers of the video information service, and in this case, as described above, the video information is provided in the manner set by the service subscriber without service collision between the same type of service and heterogeneous services. Since it is possible to do this, it is assumed that the telephones (incoming or outgoing terminals) 30, 60, and 80 of the other party making a voice call with the subscriber video telephone (calling or receiving terminal) 30 on one side are assumed to be voice-only telephones.

However, in the case of telephony video information or location-based telephony video information, pure video information set by the calling subscriber is provided to the video phone (called terminal) 30 of the other party during the voice call (when providing pure video information). Caption information can be included] [see FIG. 8]. In addition, in the case of telephony video information or location-based telephony video information, pure video information set by the called subscriber is provided to the video phone (calling terminal) 30 of the other party during the voice call (when providing pure video information). Caption information may be included] [see FIG. 7].

In Figs. 8 and 7, the telephones (calling or receiving terminals) 30, 60, and 80 of the service subscriber making a voice call with the video telephone (receiving or originating terminal) 30 on the other side are sufficient as voice-only telephones.

Meanwhile, in the first embodiment [video information / subtitle information service function], subtitle information [eg, broadcast type caption information, customized caption information, location-based type] together with the other party's video to the video telephone 30 of the calling subscriber during the video call. Subtitle information (location-based broadcasting type subtitle information, location-based customized subtitle information), etc.] (see FIG. 9). In addition, during the video call, the video subscriber 30 of the called subscriber may use subtitle information together with the other party's video (eg, broadcast caption information, customized caption information, location-based caption information (location-based broadcast caption information, location-based caption). Customized subtitle information), etc.] (see FIG. 10).

9 and 10, the telephone (incoming or outgoing terminal) 30 of the other party making a video call with the subscriber video telephone (calling or receiving terminal) 30 on one side is a video telephone.

Of course, as described above, there may be a case where both the caller and the called party are subscribers of the video information service, and in this case, subtitle information is provided in the manner set by the service subscriber without service collision even between the same type of service and heterogeneous services as described above. Since it is possible to do this, it will be described assuming that the subscriber's video telephone (calling or receiving terminal) 30 on one side has a video telephone as the telephone (called or calling terminal) 30 on the other side.

However, in the case of call caption information or location-based call caption information, the caption information set by the calling service subscriber is provided to the video phone (called terminal) 30 on the other side during the video call (see Fig. 10). In addition, in the case of call caption information or location-based call caption information, the caption information set by the called service subscriber is provided to the video phone (calling terminal) 30 of the other party during the video call (see Fig. 9).

In Figs. 10 and 9, the telephone subscriber (originating or terminating terminal) 30 of the service subscriber making a video call with the video telephone (receiving or originating terminal) 30 on the other side is a video telephone.

In the above description, the location-based image information (/ subtitle information) may be provided together with broadcast type image information (/ subtitle information), call type image information (/ caption information), and customized image information (/ caption information). The location-based broadcast type video information (/ caption information), the location-based call type video information (/ caption information), location-based customized video information (/ caption information) is possible. Accordingly, the call type video information (/ caption information), the customized video information (/ caption information), the call type video information (/ caption information) may be provided independently, and the location-based broadcast type video information (/ caption information) It is also possible to provide location-based call type video information (/ caption information) and location-based customized video information (/ caption information).

Then, a process of providing video information and / or subtitle information according to the calling / incoming service subscriber during voice or video call will be described as follows.

FIG. 7 is a flowchart illustrating a procedure for providing video information to a calling videophone during a voice call during a video information scrap service and an additional service according to the present invention.

In FIG. 7, pure video information (eg, broadcast type video information, customized video information, location-based video information (location-based broadcast video information, location-based custom video information), etc.) is used as a video telephone of a calling subscriber during a voice call. ] [Subtitle information can be included when providing pure video information]. At this time, the other party's telephones (called terminals) 30, 60, and 80 that make a voice call with the calling subscriber's video telephone (calling terminal) 30 are voice-only telephones (i.e., 'supporting only voice without video' (eg 2G mobile terminals, PSTN voice phones, etc.) or 'supported video but set to voice mode because the phone user does not want a video call' (eg SIP / H.323 / H.324 videophone, 3G Mobile communication terminals, etc.).

In addition, in the case of telephony video information or location-based telephony video information, pure video information set by the called subscriber is provided to the video phone (calling terminal) 30 of the other party during the voice call (when providing pure video information). Caption information can be included]. At this time, the telephones (receiving terminals) 30, 60 and 80 of the service subscribers who make a voice call with the video telephone (calling terminal) 30 on the other side are sufficient as voice-only telephones.

As shown in FIG. 7, first, the calling terminal (video phone) 30 attempts to call any called terminal (voice dedicated phone) 30, 60, 80 to caller A (Caller A) 30. When the sender soft switch (oSSW) 20 sets the Session Description Protocol (SDP) of the caller terminal (Caller A) and sends an INVITE message (offer SDP A), the caller soft switch 20 sets the service in the received INVITE message. A code [for example, SIP video terminal identification information (telephone number, device number, IP address, MAC address, etc.)] is checked to recognize that the caller is a subscriber of the video information service, and an INVITE message to the calling application server (oAS) 11. (offer SDP A) is passed (701). This corresponds to a case where a subscriber of a video information service selects one of broadcast type video information, customized image information, and location-based image information (eg, location-based broadcast image information and location-based customized image information). However, when the subscriber selects the call type video information or the location-based call type video information, the originating soft switch 20 checks the service code in the INVITE message to recognize that the called party is the video information service subscriber.

Of course, in the intelligent network, so that the outgoing soft switch 20 can perform the SIP call connection function smoothly, the outgoing soft switch 20 requests the connection from the outgoing terminal (video phone) 30 to the voice call through the INVITE message. When receiving the INVITE message forwarded to the calling application server (11) to ask which service the calling terminal (video phone) 30 is subscribed to follow the call processing procedure of the corresponding subscription service, for example, video information service The call may be passed to the originating application server 11.

Accordingly, the originating application server 11 sends an INVITE message (offer SDP A) back to the originating soft switch 20 (702), and the originating soft switch 20 is the called terminal (Callee B) 30, 60, 80. ) Transmits the INVITE message (offer SDP A) via switch 50, 70 or incoming soft switch (tSSW) 20 (703). Then, the called terminal (Callee B) 30, 60, 80 sends a ring response (180 Ring) message in response to the INVITE message (offer SDP A) to the switch 50, 70 or the called soft switch (tSSW) 20. (704), the outgoing soft switch 20 relays a ring response (180 Ring) message to the outgoing application server 11 (705), and outgoing application server (11). ) Again notifies the call waiting by transmitting a ring response (180 Ring) message to the calling terminal (video phone) 30 through the calling soft switch 20 (706).

Thereafter, when the called party rings and the called party answers (Hook-off), the called terminal (Callee B) (30, 60, 80) is set to the voice mode or the terminal does not support video, and responds with voice only, In this case, a 200 OK message is used (707). That is, the called terminal (Callee B) 30, 60, 80 sets the SDP of the called terminal to communicate the "200 OK (answer SDP B)" message (50, 70) or the called soft switch (tSSW) 20 (707), the originating soft switch 20 relays the " 200 OK (answer SDP B) " message to the originating application server 11 (708), and the originating application. The server 11 again transmits a "200 OK (answer SDP B)" message to the calling terminal (video phone) 30 through the calling soft switch 20 (709). In response to this, the calling terminal (video phone) 30 transmits an "ACK" message confirming that the message has been received to the calling application server 11 through the calling soft switch 20 (711), and the calling application server 11 ) Transmits the " ACK " message to the called terminal (voice dedicated telephone) 30, 60, 80 via the switch 50, 70 or the incoming soft switch (tSSW) 20 via the outgoing soft switch 20. (713). At this time, the "ACK" message is to inform the opening of the voice call (voice channel).

In the above, the originating application server 11 transmits a "200 OK (answer SDP B)" message to the calling terminal (video phone) 30 (709), from the calling terminal (video phone) 30 In transmitting the " ACK " message to the called terminal (voice dedicated phone) 30, 60, 80 (711, 713), the calling application server 11 sends the calling number (or IP of the calling terminal) for the location-based video information service. The area code is inquired to the location information management server 15 based on the address (710), and the area code (for example, the same code) is received from the location information management server 15 (712). That is, the acquisition of the location information may be obtained before the " ACK " message is transmitted to the called terminal (voice dedicated telephone) 30, 60, 80. This process is for location-based video information (eg, location-based broadcast video information, location-based call video information, location-based custom video information).

Thereafter, a voice RTP channel (voice call path) is formed between the calling terminal (video phone) 30 and the called terminal (voice dedicated phone) 30, 60, 80 to make a voice call between the caller and the caller (714).

On the other hand, during a voice call, the calling application server 11 transmits a "RE-INVITE (no SDP)" message without SDP information to the calling terminal (video phone) 30 through the calling soft switch 20 to provide an image. (715). On the other hand, the calling terminal (video phone) 30 sets the SDP of the calling terminal and transmits a "200 OK (offer SDP A)" message to the calling application server 11 through the calling soft switch 20 (716). ).

Thereafter, the calling application server 11 loads the SDP information of the calling terminal (video phone) 30 to the media server 13 in a new INVITE (offer SDP video A) message and transmits the same to the media server 13 (717). The media server (MS) 13 responds (718) to the originating application server 11 via the SDP information of the media server through a "200 OK (answer SDP video MS)" message. In response, the originating application server 11 transmits an "ACK" message to the media server 13 (719), and in response to the "200 OK" message from the originating terminal (videophone) 30, "ACK". The message SDP is re-negotiated by transmitting a message to the calling terminal (video phone) 30 through the calling soft switch 20 (720).

When the negotiation is completed, the originating application server 11 is the video information to be reproduced (for example, broadcast video information, call video information, custom video information, location-based video information (location-based broadcast video information, location-based Call type video information, location-based customized video information), etc.] or the VXML-URL address in the " INFO " message and transmits it to the media server 13 (721). In response to the "INFO" message, the message "200 OK" is transmitted to the originating application server 11 (722). In addition, when the media server 13 receives the ID, the media server 13 queries the content DB 14 to retrieve the corresponding video information and plays the video information on the calling terminal (video phone) 30 through the video RTP channel (video call path) (725). . If the VXML URL information is received, the media server 13 requests the video information from the video information management server 12 to obtain the video information, and the calling terminal (video phone) through the video RTP channel (video call path). Play back at (30) (723-725).

Here, the media server 13 forms a dialogue with the video information management server 12 in the form of a request and a response through HTTP, and retrieves the video information and plays it through the video channel.

In this case, pure image information consisting of only images may be provided, or subtitle information may be provided together with pure image information. In addition, as described above, broadcast type video information (which may include subtitle information), call type video information (which may include subtitle information), and customized image information (which may include subtitle information) may be independently provided, and broadcasting may be performed based on location. Type image information (caption information may be included), location-based call type image information (caption information may be included), and location-based customized image information (caption information may be included) may be provided.

8 is a flowchart illustrating a procedure of providing video information to a called videophone during a voice call during a video information scrap service and an additional service according to the present invention.

In FIG. 8, pure video information (eg, broadcast type video information, customized video information, location-based video information (location-based broadcast video information, location-based custom video) to the video subscriber 30 of the called subscriber during a voice call. Information), etc. [caption information can be included when providing pure video information]. At this time, the other party's telephones (calling terminals) 30, 60, and 80 that make a voice call with the called subscriber's video telephone (called terminal) 30 are voice-only telephones (i.e., 'supporting only voice' without video) (eg 2G mobile terminal, PSTN voice phone, etc.) or 'supports video but is set up in voice mode because the phone user does not want to make a video call' (eg SIP / H.323 / H.324 videophone, 3G mobile) Communication terminals, etc.).

In addition, in the case of telephony video information or location-based telephony video information, pure video information set by the calling subscriber is provided to the video phone (called terminal) 30 on the other side during the voice call (when providing pure video information). Caption information can be included] [see FIG. 8]. At this time, the telephones (receiving terminals) 30, 60, and 80 of the service subscribers who make a voice call with the video telephone (receiving terminal) 30 on the other side may be a voice-only telephone.

As shown in FIG. 8, first, an arbitrary calling terminal (voice-only phone) 30, 60, 80 attempts to call the called terminal (video phone) 30 to caller A (Caller A) 30. Set the SDP of the calling terminal (Caller A) with the switch 50, 70 or the calling soft switch (oSSW) 20 (in this case, the calling terminal is set to voice mode or set to voice only because it does not support video). ], When sending an INVITE message (offer SDP A), the exchange 50 or 70 or the outgoing soft switch 20 may send a service code [eg, SIP video terminal identification information (telephone number, device number) in the received INVITE message. , IP address, MAC address)] to recognize that the called party is a subscriber of the video information service, and the INVITE message (offer SDP) to the called soft switch (tSSW) 20 where the called terminal (Callee B) 30 is located. A) is passed (801). In response, the incoming soft switch 20 transmits an INVITE message (offer SDP A) to the incoming application server (tAS) 11 (802). This corresponds to a case where a subscriber of a video information service selects one of broadcast type video information, customized image information, and location based image information (location based broadcast type image information and location based customized image information). However, when the subscriber selects the call type video information or the location-based call type video information, the incoming soft switch 20 checks the service code in the INVITE message and recognizes that the caller is the video information service subscriber.

Of course, in the intelligent network, the incoming soft switch 20 can perform the SIP call connection function smoothly. In the incoming soft switch 20, the INVITE message is transmitted from the calling terminal (voice-only phone) 30, 60, 80. When a connection request is received by a voice call, an INVITE message is forwarded to the destination application server 11 to inquire which service the destination terminal (video phone) 30 is subscribed to, and a call of the corresponding subscription service, for example, a video information service. The call may be passed to the destination application server 11 to follow the processing procedure.

Accordingly, the incoming application server 11 sends the INVITE message (offer SDP A) back to the incoming soft switch 20, and the incoming soft switch 20 sends the INVITE message (offer SDP) to the called terminal (video phone) 30. A) is passed (803). Then, the called terminal (video phone) 30 sends a ring response (180 Ring) message to the called application server 11 via the called soft switch (tSSW) 20 in response to the INVITE message (offer SDP A). Forward 804, the destination application server 11 forwards the ring response (180 Ring) message to the incoming soft switch 20 (805), and the incoming soft switch 20 sends back the ring response (180 Ring) message. The switch 50, 70 or the calling soft switch 20 communicates with the calling terminal (voice dedicated phone) 30, 60, 80 to notify the call waiting (806).

Thereafter, when the called ringer rings and the called party responds (hook-off), the called terminal (video phone) 30 responds to the video only because it is a terminal supporting video, using a 200 OK message (807). That is, the called terminal (Callee B) 30 sets the SDP of the called terminal and transmits a "200 OK (answer SDP B)" message to the calling called application server 11 through the called soft switch (tSSW) 20. (807), the destination application server 11 forwards a "200 OK (answer SDP B)" message to the destination soft switch 20 (808), and the destination soft switch 20 is again switched (50, 70) Alternatively, the message “200 OK (answer SDP B)” is transmitted to the calling terminal (voice dedicated phone) 30, 60, 80 via the calling soft switch 20 (809). On the other hand, the calling terminal (voice-only telephone) 30, 60, 80 sends an " ACK " message confirming that the message has been received via the switching 50, 70 or the calling soft switch 20 to the incoming soft switch 20. In step 811, the destination application server 11 transmits an "ACK" message to the destination terminal (video phone) 30 through the destination soft switch 20 (813). ). At this time, the "ACK" message is to inform the opening of the voice call (voice channel).

In the above, the destination application server 11 delivers a message "200 OK (answer SDP B)" to the calling terminal (voice dedicated telephone) 30, 60, 80 (808, 809), the calling terminal (voice dedicated telephone) In transmitting the " ACK " message from 30, 60 and 80 to the called terminal (video phone) 30 (811, 813), the called application server 11 receives the called number (for the location-based video information service). Alternatively, the area code is inquired to the location information management server 15 based on the IP address of the called terminal (810), and the area code (for example, the same code) is received from the location information management server 15 (812). ). That is, the acquisition of the location information may be obtained before the "ACK" message is transmitted to the called terminal (video phone) 30. This process is for location-based video information (location-based broadcast video information, location-based call video information, location-based customized video information).

Thereafter, a voice RTP channel (voice call path) is formed between the calling terminal (voice dedicated phone) 30, 60, 80 and the called terminal (video phone) 30 to make a voice call between the caller and the caller (814).

On the other hand, during the voice call, the incoming application server 11 transmits a "RE-INVITE (no SDP)" message without SDP information to the called terminal (video telephone) 30 through the incoming soft switch 20 to provide an image. (815). In contrast, the called terminal (video phone) 30 sets the SDP of the called terminal and transmits a "200 OK (offer SDP B)" message to the called application server 11 through the called soft switch 20 (816). ).

Then, the destination application server 11 loads the SDP information of the destination terminal (video phone) 30 to the media server 13 in a new INVITE (offer SDP video B) message and transmits it to the media server 13 (817). In operation 818, the media server (MS) 13 responds to SDP information of the media server to the destination application server 11 through the message “200 OK (answer SDP video MS)”. In response, the terminating application server 11 transmits the "ACK " message to the media server 13 (819), and " ACK " in response to the " 200 OK " message from the terminating terminal (videophone) 30. The message is transmitted to the called terminal (video phone) 30 through the incoming soft switch 20 to negotiate the video SDP again (820).

When the negotiation is completed, the destination application server 11 is the video information to be reproduced (for example, broadcast type video information, call type video information, customized video information, location-based video information (location-based broadcast video information, location-based) Call type video information, location-based customized video information), etc.] or VXML-URL address in the " INFO " message and transmits it to the media server 13 (821). In response to the "INFO" message, the message "200 OK" is transmitted to the destination application server 11 (822). When the media server 13 receives the ID, the media server 13 queries the content DB 14 to obtain the corresponding video information and plays the video information on the called terminal (video phone) 30 through the video RTP channel (video call path) (825). . If the VXML URL information is received, the media server 13 requests the video information from the video information management server 12 to obtain the video information, and receives the video information through the video RTP channel (video call path). Playback at (30) (823 to 825).

Here, the media server 13 forms a dialogue with the video information management server 12 in the form of a request and a response through HTTP, and retrieves the video information and plays it through the video channel.

In this case, pure image information consisting of only images may be provided, or subtitle information may be provided together with pure image information. In addition, as described above, broadcast type video information (which may include subtitle information), call type video information (which may include subtitle information), and customized image information (which may include subtitle information) may be independently provided, and broadcasting may be performed based on location. Type image information (caption information may be included), location-based call type image information (caption information may be included), and location-based customized image information (caption information may be included) may be provided.

FIG. 9 is a flowchart illustrating a procedure of providing video information (/ subtitle information) to a calling videophone during a video call during a video information scrap service and an additional service according to the present invention.

9 shows subtitle information [eg, broadcast type caption information, customized caption information, location-based caption information (location-based broadcast caption information, location-based) with the other party's video to the video telephone 30 of the calling subscriber during the video call. Custom subtitle information). At this time, the calling party's video telephone (calling terminal) 30 and the other party's telephone (called terminal) 30, 60 making a video call support the video and set the video mode (eg, video telephone, 3G mobile communication). Terminal).

In addition, in the case of call caption information or location-based call caption information, the caption information set by the called service subscriber is provided to the video phone (calling terminal) 30 on the other side during the video call. At this time, the service subscriber's telephones (called terminals) 30 and 60 that make video calls with the video telephone (calling terminal) 30 of the other party support the video and are set to the video mode (eg, video telephone, 3G mobile). Communication terminals).

As shown in FIG. 9, first, the calling terminal (video phone) 30 attempts to call any called terminal (video phone) 30, 60 to make a soft call in the calling terminal (Caller A) 30. (OSSW) 20 If the Session Description Protocol (SDP) of the calling terminal (Caller A) is set, and an INVITE message (offer SDP A) is sent, the calling soft switch 20 sets the service code in the received INVITE message [Example SIP video terminal identification information (telephone number, device number, IP address, MAC address, etc.)] to recognize that the caller is a subtitle information service subscriber, and to the originating application server (oAS) 11 an INVITE message (offer SDP). A) (901). This is the case when the subscriber of the subtitle information service selects one of broadcast type subtitle information, customized subtitle information, and location-based subtitle information (location-based broadcast subtitle information and location-based custom subtitle information). However, when the subscriber selects the monetary caption information or the location-based monetary caption information, the originating soft switch 20 checks the service code in the INVITE message to recognize that the called party is the subtitle information service subscriber.

Of course, in the intelligent network, so that the outgoing soft switch 20 smoothly performs the SIP call connection function, the outgoing soft switch 20 requests connection from the outgoing terminal (video phone) 30 to the video call through the INVITE message. When receiving the INVITE message forwarded to the calling application server (11) to ask which service the calling terminal (video phone) 30 is subscribed to follow the call processing procedure of the corresponding subscription service, such as subtitle information service The call may be passed to the originating application server 11.

Accordingly, the originating application server 11 sends an INVITE message (offer SDP A) back to the originating soft switch 20 (902), and the originating soft switch 20 sends a caller terminal (Callee B) 30,60. The INVITE message (offer SDP A) is delivered (903) via the exchange 50 or the incoming soft switch (tSSW) 20 to the location. Then, the called terminal (Callee B) 30,60 sends a ring response (180 Ring) message in response to the INVITE message (offer SDP A) via the switch 50 or the incoming soft switch (tSSW) 20. Forwarding to the outgoing soft switch 20 (904), outgoing soft switch 20 relays a ring response (180 Ring) message to the outgoing application server 11 (905), outgoing application server 11 again outgoing The call waiting message is notified by transmitting a ring response (180 Ring) message to the calling terminal (video phone) 30 through the soft switch 20 (906).

Thereafter, when the called party rings and the called party answers (Hook-off), the called terminal (video phone) 30, 60 supports the video and is set to the video mode so that the answer is made for video only. Use an OK message (907). That is, the called terminal (Callee B) 30, 60 sets the SDP of the called terminal and sends a "200 OK (answer SDP B)" message through the exchange 50 or the called soft switch (tSSW) 20. Forwarding to the soft switch 20 (907), the outgoing soft switch 20 relays a "200 OK (answer SDP B)" message to the outgoing application server 11 (908), the outgoing application server 11 In step 909, the message “200 OK (answer SDP B)” is transmitted to the calling terminal (video phone) 30 through the calling soft switch 20. On the other hand, the calling terminal (video phone) 30 transmits an "ACK" message confirming that the message has been received to the calling application server 11 through the calling soft switch 20 (911), the calling application server ( 11 transmits the " ACK " message to the called terminal (video telephone) 30, 60 via the switching softener 20, via the switch 50 or the incoming soft switch (tSSW) 20 (913). . At this time, the "ACK" message is to inform the opening of the voice and video RTP call (voice and video channels).

In the above, the calling application server 11 transmits the message "200 OK (answer SDP B)" to the calling terminal (video phone) 30 (909), from the calling terminal (video phone) 30 In transmitting the " ACK " message to the called terminal (video phone) 30,60 (911,913), the calling application server 11 sends the calling number (or IP address of the calling terminal) for the location-based subtitle information service. As a reference, the location code management server 15 inquires the area code (910), and receives the area code (for example, the same code) from the location information management server 15 (912). That is, the acquisition of the location information may be obtained before the " ACK " message is transmitted to the called terminal (video phone) 30,60. This process is for location-based subtitle information (location-based subtitle information, location-based call subtitle information, location-based custom subtitle information).

Subsequently, a voice and video RTP channel (voice call path and video call path) is formed between the calling terminal (video phone) 30 and the called terminal (video phone) 30, 60 to establish a voice and video call between the called party and the called party. (914).

Meanwhile, during the voice and video call, the calling application server 11 transmits the caption information URL address to the "INFO" message to the calling terminal (video phone) 30 to provide the caption information (915). In response to this, the calling terminal (video phone) 30 transmits a "200 OK" message to the calling application server 11 in response to the "INFO" message (916). Then, the calling terminal (video phone) 30 forms a conversation with the video information management server (which is the subtitle information management server) 12 in the form of a request and a response through HTTP, and the caption information corresponding to the subtitle information URL information is formed. The video is mixed with the video of the other party and played.

In this case, the caption information may independently provide broadcast caption information, call caption information, and customized caption information along with the other party's video during the video call, and broadcast caption information based on location, call caption information based on location, and location. You can also provide customized subtitle information based on.

FIG. 10 is a flowchart illustrating a procedure of providing image information (/ subtitle information) to a called videophone during a video call during a video information scrap service and an additional service according to the present invention.

In FIG. 10, subtitle information [eg, broadcast type caption information, customized caption information, location-based caption information (location-based broadcast caption information, location-based) together with the other party's video to the video telephone 30 of the called subscriber during the video call is shown. Custom subtitle information). At this time, the other party's telephones (calling terminals) 30 and 60 that make video calls with the called subscriber's video telephone (called terminal) 30 support video and are set to a video mode (eg, video telephone, 3G mobile communication). Terminal).

In addition, in the case of the call type subtitle information or the location-based call type subtitle information, the subtitle information set by the calling service subscriber is provided to the video telephone (the called terminal) 30 on the other side during the video call. At this time, the telephone subscriber (calling terminal) 30, 60 of the service subscriber who makes a video call with the video telephone (called terminal) 30 of the other party supports the video and is set to the video mode (eg, video telephone, 3G mobile). Communication terminals).

As shown in Fig. 10, any caller terminal (video phone) 30,60 first attempts to call the caller terminal (videophone) 30 so that the caller terminal (Caller A) 30 switches 50. Or SDP of the caller terminal (Caller A) with the caller soft switch (oSSW) 20 (in this case, the caller terminal supports the video and is set to the video mode. When the offer SDP A) is sent, the exchange 50 or the outgoing soft switch 20 may display the service code in the received INVITE message (eg, SIP video terminal identification information (telephone number, device number, IP address, MAC address, etc.)]. The receiver recognizes that the called party is a subscriber of the subtitle information service, and transmits an INVITE message (offer SDP A) to the called soft switch (tSSW) 20 where the called terminal (Callee B) 30 is located (1001). In response, the incoming soft switch 20 transmits an INVITE message (offer SDP A) to the incoming application server (tAS) 11 (1002). This is the case when the subscriber of the subtitle information service selects one of broadcast type subtitle information, customized subtitle information, and location-based subtitle information (location-based broadcast subtitle information and location-based custom subtitle information). However, when the subscriber selects the monetary caption information or the location-based monetary caption information, the incoming soft switch 20 checks the service code in the INVITE message to recognize that the caller is the subtitle information service subscriber.

Of course, in the intelligent network, the incoming soft switch 20 smoothly performs the SIP call connection function. In the incoming soft switch 20, the video call through the INVITE message from the calling terminal (video phone) 30, 60 is performed. When a connection request is received, the INVITE message is forwarded to the destination application server 11 to inquire which service the destination terminal (video phone) 30 is subscribed to, and the call processing procedure of the corresponding subscription service, for example, a subtitle information service. The call may be passed to the destination application server 11 to follow.

Accordingly, the incoming application server 11 sends the INVITE message (offer SDP A) back to the incoming soft switch 20, and the incoming soft switch 20 sends the INVITE message (offer SDP) to the called terminal (video phone) 30. A) is passed (1003). Then, the called terminal (video phone) 30 sends a ring response (180 Ring) message to the called application server 11 via the called soft switch (tSSW) 20 in response to the INVITE message (offer SDP A). Forwarding (1004), the destination application server 11 forwards the ring response (180 Ring) message to the incoming soft switch 20 (1005), and the incoming soft switch (20) sends back the ring response (180 Ring) message The call is transmitted to the calling terminal (video phone) 30, 60 through the switch 50 or the calling soft switch 20 (1006).

Thereafter, when the called party rings and the called party responds (hook-off), the called terminal (video phone) 30 responds to the video only because it is a terminal supporting the video, at which time 200 OK message is used (1007). That is, the called terminal (Callee B) 30 sets the SDP of the called terminal and transmits a "200 OK (answer SDP B)" message to the calling called application server 11 through the called soft switch (tSSW) 20. (1007), the destination application server 11 forwards the "200 OK (answer SDP B)" message to the destination soft switch 20 (1008), and the destination soft switch 20 is again switched to the exchange 50 or originating. The soft switch 20 transmits the message “200 OK (answer SDP B)” to the calling terminal (video phone) 30 or 60 (1009). On the other hand, the calling terminal (video telephone) 30, 60 receives the " ACK " message confirming that the message has been received by the incoming soft switch 20 via the exchange 50 or the outgoing soft switch 20. Sending to the server 11 (1011), the destination application server 11 transmits an "ACK" message to the destination terminal (video phone) 30 through the incoming soft switch 20 (1013). At this time, the "ACK" message is to inform the opening of the voice and video RTP call (voice and video channels).

In the above, the destination application server 11 delivers the message "200 OK (answer SDP B)" to the calling terminal (video phone) (30, 60) (1008, 1009), the calling terminal (video phone) ( In transmitting the " ACK " message from 30,60 to the called terminal (video phone) 30 (1011, 1013), the called application server 11 receives the called number (or called) for location-based subtitle information service. The area code is inquired to the location information management server 15 based on the IP address of the terminal (1010), and the area code (for example, the same code) is received from the location information management server 15 (1012). That is, the acquisition of the location information may be obtained before the "ACK" message is transmitted to the called terminal (video phone) 30. This process is for location-based subtitle information (location-based subtitle information, location-based call subtitle information, location-based custom subtitle information).

Thereafter, a voice and video RTP channel (voice call path and video call path) is formed between the calling terminal (video phone) 30 and 60 and the called terminal (video phone) 30 so that voice and video calls are made between the caller and the called party. (1014).

On the other hand, during voice and video calls, the destination application server 11 transmits the caption information URL address to the "INFO" message to the destination terminal (video phone) 30 to provide the caption information (1015). On the other hand, the called terminal (video phone) 30 transmits the message "200 OK" to the calling application server 11 in response to the "INFO" message (1016). In addition, the called terminal (video phone) 30 forms a conversation with the video information management server (which is a subtitle information management server) 12 in the form of a request and a response through HTTP, and the caption information corresponding to the caption information URL information is received. The video is mixed with the video of the other party and played.

In this case, the caption information may independently provide broadcast caption information, call caption information, and customized caption information, and provide broadcast caption information based on location, call caption information based on location, and customized caption information based on location. You may.

In the above, the scenario of providing a separate voice channel and a video channel to provide the video resource (/ subtitle information) for the efficiency of the network resources has been exemplified, but the MCU function such as the media server 13 and the voice / video switching technology / function It is also possible to provide video information (/ subtitle information) without separating the video / audio channel.

Now, the image information / subtitle information scrap service process [second embodiment] and the additional service process [third embodiment] according to the present invention will be described in more detail with reference to FIGS. 13 and 14.

In the embodiment 2-1 [video information scrap service function], through the first embodiment [video information service function], pure video information [for example, broadcast is provided to the video telephone 30 of the calling subscriber during a voice call]. Type video information, customized video information, location-based video information (location-based broadcast video information, location-based custom video information, etc.) (where subtitle information may be included when providing pure video information) during a voice call [See FIG. 13]. In addition, the pure video information (eg, broadcast type video information, customized video information, location-based video information (location-based broadcast video information, location-based customized) provided to the video subscriber 30 of the called subscriber during the voice call. Video information), etc. (at this time, subtitle information may be included in providing pure video information) during a voice call (see FIG. 14).

In FIG. 13 and FIG. 14, before the scrap, the other party's telephone (incoming or outgoing terminal) 30, 60, 80, which has a voice call with the subscriber video telephone (calling or receiving terminal) 30 on one side, is a voice-only telephone. It is enough. In addition, the secondary terminating terminal connected by the subscriber video telephone (calling or terminating terminal) (which becomes the calling terminal in case of an additional service function) 30 on one side may be a voice-only telephone (30, 60, 80).

Of course, as described above, there may be a case where both the caller and the called party are subscribers of the video information service, and in this case, as described above, the video information is provided in the manner set by the service subscriber without service collision between the same type of service and heterogeneous services. Since it is possible to do this, it is assumed that the telephones (incoming or outgoing terminals) 30, 60, and 80 of the other party making a voice call with the subscriber video telephone (calling or receiving terminal) 30 on one side are assumed to be voice-only telephones.

However, in the case of telephony video information or location-based telephony video information, since the pure video information set by the calling subscriber during the voice call is provided to the video phone (called terminal) 30 of the other party [pure video information is provided]. Caption information can be included at the time], the video phone (called terminal) 30 of the other party can be scrapped during a voice call (see Fig. 14). In addition, in the case of telephony video information or location-based telephony video information, since the pure video information set by the called subscriber during the voice call is provided to the video phone (calling terminal) 30 of the other party (when providing pure video information). Caption information can be included], the video phone (calling terminal) 30 on the other side can be scraped during a voice call (see Fig. 13).

14 and 13, if the telephones (calling or receiving terminals) 30, 60, and 80 of the service subscriber making a voice call with the video telephone (called or calling terminal) 30 on the other side before the scrap are voice-only phones, It is enough. In addition, if the secondary called terminal connected by the video telephone (incoming or outgoing terminal) 30 of the other side (which becomes the outgoing terminal in case of an additional service function) 30 is a voice-only telephone (30, 60, 80), It is enough.

On the other hand, in Example 2-2, subtitle information (eg, broadcast type caption information, provided with the other party's video to the video telephone 30 of the calling subscriber during the video call in the first embodiment [subtitle information service function]) is provided. Custom subtitle information, location-based subtitle information (location-based subtitle information, location-based custom subtitle information, etc.) may be scraped during a video call (see FIG. 13). In addition, subtitle information (eg, broadcast-type subtitle information, customized subtitle information, location-based subtitle information (location-based broadcast type subtitle information, location) provided to the subscriber's video phone 30 with the other party's video during a video call. Based customized subtitle information), etc.] can be scraped during a video call (see FIG. 14).

In Fig. 13 and Fig. 14, before the scrap, the other party's telephone (incoming or outgoing terminal) 30, which has a video call with the subscriber's video telephone (calling or receiving terminal) 30, is a video telephone. In addition, the secondary terminating terminal connected by the subscriber video telephone (calling or terminating terminal) (which becomes the calling terminal in case of an additional service function) 30 on one side may be a voice-only telephone (30, 60, 80).

Of course, as described above, there may be a case where both the caller and the called party are subscribers of the video information service, and in this case, subtitle information is provided in the manner set by the service subscriber without service collision even between the same type of service and heterogeneous services as described above. Since it is possible to do this, it will be described assuming that the subscriber's video telephone (calling or receiving terminal) 30 on one side has a video telephone as the telephone (called or calling terminal) 30 on the other side.

However, in the case of call type subtitle information or location-based call type subtitle information, since the subtitle information set by the calling service subscriber is provided to the other party's video phone (called terminal) 30 during the video call, the other party's video phone ( Incoming terminal) can be scraped during the video call (see Fig. 14). In addition, in the case of call caption information or location-based call caption information, the caption information set by the called service subscriber is provided to the video phone (calling terminal) 30 of the called party during the video call. Caller terminal 30 may be scraped during a video call (see FIG. 13).

In Fig. 14 and Fig. 13, before the scrap, the telephone subscriber (originating or terminating terminal) 30 of the service subscriber making a video call with the video telephone (incoming or originating terminal) 30 on the other side is a video telephone. In addition, the secondary terminating terminal connected by the video telephone (incoming or originating terminal) of the other party (which becomes the originating terminal in case of the additional service function) 30 may be a voice-only telephone (30, 60, 80).

In the above description, the location-based image information (/ subtitle information) may be provided together with broadcast type image information (/ subtitle information), call type image information (/ caption information), and customized image information (/ caption information). The location-based broadcast type video information (/ caption information), the location-based call type video information (/ caption information), location-based customized video information (/ caption information) is possible. Accordingly, the call type video information (/ caption information), the customized video information (/ caption information), the call type video information (/ caption information) may be provided independently, and the location-based broadcast type video information (/ caption information) It is also possible to provide location-based call type video information (/ caption information) and location-based customized video information (/ caption information).

Then, the procedure for scraping the video information and / or subtitle information provided during a voice or video call is classified according to calling / incoming service subscribers.

FIG. 13 is a flowchart illustrating a procedure of scraping image information (/ subtitle information) to a calling videophone and using an additional service of scrap image information (/ subtitle information) among the video information scrap service and additional service method according to the present invention. One embodiment flow diagram is shown.

As described above, according to the embodiments 1-1 to 1-4, during a voice call between the calling / calling terminal, one side terminal (assuming the calling terminal) connected to the media server 13 through the video channel. It has been suggested that image information (which may include subtitle information) or location-based image information (which may include subtitle information) may be provided. In this case, a voice channel is connected between the calling / calling terminal (1301) and the video server information of the media server 13 is transmitted to one terminal (calling terminal) of the calling / calling terminal, so that the media server 13 and one terminal ( The video channel is connected between the calling terminal (1302).

However, according to the embodiments 1-5 to 1-8, subtitle information or location-based subtitle information may be provided to one terminal (assuming a calling terminal) during a video call between the calling / calling terminals. In this case, although not shown in the figure, voice and video channels are connected between the calling / called terminal.

Therefore, the video information / subtitle information is continuously displayed on the screen of one terminal (assuming the calling terminal) (video telephone 30) among the calling / receiving terminals in the voice or video call (for example, Image information 15a, 15b, and 15c shown in FIG. 15 are sequentially shown).

If the user (sender) presses a scrap input signal (expression of scraping on the currently viewed video information / subtitle information) to scrap the video information / advertisement information provided during a call, the corresponding information (scrap request information) Is sent to the originating application server (oAS) 11 via the originating soft switch (oSSW) 20 via an INFO message [INFO (Scrap Now)] 1303. At this time, the outgoing soft switch 20 recognizes the scrap request information through the received INFO message and delivers an INFO (Scrap Now) message to the outgoing application server 11.

Accordingly, the calling application server 11 is a video information management server (caption information management server) 12, the scrap of the video information / caption information based on the telephone number and IP address of the caller terminal (Caller A) 30 Request (1304) and receive a response code from the video information management server (caption information management server) 12 (1305). At this time, the originating application server 11 transmits a message requesting to scrap the video information / subtitle information currently being played to the video information management server (subtitle information management server) 12 together with the phone number and IP address. The video information management server (subtitle information management server) 12 stores the scrap image information / subtitle information in the scrap DB 125 for each user based on the telephone number and the IP address. The originating application server 11 transmits a "200 OK" message to the originating terminal 30 in response to the INFO message from the originating terminal 30 (1306).

Steps 1303 to 1306 may be repeatedly performed during a call, and a user (sender) may selectively scrap desired information among video information / subtitle information provided during a call.

As described above, when the caller A 30 and the caller B 30, 60, 80 are in a voice or video call state, a call is terminated normally through a message transfer when a call termination request is received from one side. (1307-1312).

That is, as an example, when the call is terminated by the calling terminal 30, the calling terminal 30 transmits a call termination (BYE) message to the calling application server 11 through the calling soft switch 20. 1307, the originating application server 11 sends the " BYE " message again via the originating soft switch 20 via the switch 50, 70 or the terminating soft switch (tSSW) 20 to the called terminal (Callee B). Send to (30, 60, 80) to terminate the call (1308, 1309). In response, the called terminal 30, 60, 80 transmits a " 200 OK " message to the calling soft switch 20 via the switch 50,70 or the called soft switch 20 in response (1310). , The outgoing soft switch 20 relays the "200 OK" message to the outgoing application server 11 (1311), the outgoing application server 11 back to the outgoing terminal 30 through the outgoing soft switch 20 " 200 OK "message is sent (1312). At this time, the originating terminal 30 transmits an "ACK" message confirming that the message has been received to the originating application server 11 through the originating soft switch 20, thereby ending the call between the originating and receiving terminals (1313).

Subsequently, when the caller terminal 30 presses an automatic connection or a specific access code according to a setting in order to view the scraped image information / subtitle information after the call, the INVITE message is transmitted from the caller terminal 30 toward the caller soft switch 20. [INVITE (offer SDP A)], the outgoing soft switch 20 transmits the INVITE message to the outgoing application server 11 by recognizing the subscriber's connection request to the scrap image information / subtitle information through the service code in the message. (1314).

Then, the originating application server 11 loads the VoiceXML document URL in the INFO message [INVITE (offer SDP A)] and transmits it to the media server 13 to make a connection request for the scrap image information / subtitle information (1315). In response, the media server 13 transmits the message “200 OK (answer SDP MS)” to the calling application server 11 in response to the “INFO” message (1316), and the calling application server 11 sends the message. The message “ACK” is sent to the media server 13 acknowledging receipt (1317). In addition, the originating application server 11 transmits a "200 OK (answer SDP MS)" message to the originating terminal 30 through the originating soft switch 20 in response to the "INVITE" message of the originating terminal 30. In operation 1318, the originating terminal 30 transmits an "ACK" message to the originating application server 11 through the originating soft switch 20 confirming that the message has been received (1319).

Subsequently, when the "ACK" message is received from the calling terminal 30, the calling application server 11 carries the VoiceXML URL information necessary for providing the scrap menu to the "INFO" message to the media server 13 (1320). The media server 13 forwards the "200 OK" message to the calling application server 11 in response to the "INFO" message (1321), and the calling application server 11 confirms that the message has been received. Message is sent to the media server 13 (1322). The media server 13 extracts the VoiceXML document URL information from the received INFO message and transmits the VoiceXML document URL to the video information management server (subtitle information management server) 12 using HTTP to execute the service script. (1323) That is, an HTTP request message is created with the VoiceXML document URL value and transmitted to the video information management server (subtitle information management server) 12 to request the VoiceXML document.

Subsequently, when a VoiceXML document (sound file and video file), which is a service script, is received in response to the HTTP request message from the video information management server (subtitle information management server) 12 (1324), the media server 13 receives the received information. An image file (menu-selected scrap image information / subtitle information screen) and a sound source file generated by parsing, interpreting, and executing a VoiceXML document are transmitted to the calling terminal 30 through a real time transmission protocol (RTP) (1325).

At this time, when the menu-selected scrap image information / subtitle information screen and the announcement broadcast transmitted through the real-time transmission protocol (RTP) are transmitted to the user (sender), the media server 13 transmits the caller and the image information management server (subtitle information). The interaction between the management server) 12 is relayed (1325). Looking at this in detail.

Menu-selected scrap image information / subtitle information screen reproduced in the videophone 30 via a real-time transmission protocol (RTP) [for example, '1. Car advertising ',' 2. Chicken advertising ',' 3. Through the scrap list of movie advertisements] and announcements, when a user (sender) who wants to use the supplementary service sees a menu image and presses a menu number [for example, in the scrap list, the " 1. Car advertisement '], and the media server 13 receiving the menu number through the real-time transmission protocol (RTP) displays the menu number of the additional service that the caller wants through the DTMF signal extraction process through the VoiceXML script interaction process. The information management server (subtitle information management server) 12, and the video information management server (subtitle information management server) 12 to the menu number determined by the caller, re-view function, detailed information view function, telephone connection Corresponding VoiceXML document for function [For example, if No. 1 is selected, the submenu as' 1. Watch again ',' 2. Detailed description (price, etc.) ',' 3. Menu selection screens such as 'calling consultation call' and 'returning to the previous menu'] are transmitted to the media server 13 through the HTTP protocol, and the media server 13 interprets the VoiceXML document to select menu-type scrap image information / subtitles. The information screen and the sound source file are transmitted to the calling terminal (video phone) 30.

The relay process 1325 is a video information management server by pressing the caller to the menu number (for example, replay selection, detail view selection, telephone connection selection) that can end the menu selection scrap image information / subtitle information screen selection process It is repeated until the final VoiceXML document is received from the (caption information management server) 12. In other words, if the final VoiceXML document is not received, the step continues to receive the menu number from the sender. This assumes that the replay feature, the details view feature, and in particular the telephony feature, are in the final VoiceXML document (submenu).

If the caller presses a menu number (for example, selecting to make a phone call) where the menu selection type scrap image information / subtitle information screen selection process can be terminated, the media server 13 connects the incoming call of the corresponding VoiceXML document. The telephone number is obtained from the video information management server (subtitle information management server) 12, and a session control request message to which the incoming connection telephone number is added is sent to the calling application server 11 (1326). The originating application server 11 receiving this transmits a session control response message to the media server 13 (1327), and sends a session start request message (INVITE message) through the originating soft switch 20 to the switch 50 and 70. Or, via the incoming soft switch 20, it transmits to the telephones (secondary terminating terminals) 30, 60, and 80 of the final destination (1328).

Subsequently, the secondary destination terminal (Callee C) 30, 60, 80, which is the final destination telephone, sends a session initiation in progress message (180 Ring message) to the exchange 50, 70 or the session initiation request message (INVITE message). Via the outgoing soft switch 20 to the outgoing application server 11 via the outgoing soft switch 20 (1329), outgoing application server 11 through the "RE-INVITE" message for the ring back tone processing. The media information is renegotiated (1330 and 1331). That is, the calling application server 11 transmits a "RE-INVITE (no SDP)" message without SDP information to the calling terminal (video phone) 30 through the calling soft switch 20 for processing the RBT ( 1330, the calling terminal (video phone) 30 sets the SDP of the calling terminal and transmits a "200 OK (offer SDP A)" message to the calling application server 11 through the calling soft switch 20. (1331).

When the called party rings and the last called party (e.g., an agent) receives a call (hook-off) to answer the call, a session start response message (200 OK message) passes through the soft switch 20 to the application server ( 11) (1333). That is, the secondary called terminal (Callee C) 30, 60, 80 sets the SDP of the called terminal and sends a "200 OK (SDP C)" message via the switch 50, 70 or the called soft switch 20. To the outgoing application server 11 through the outgoing soft switch 20.

Then, the originating application server 11 again transmits the message "200 OK (SDP C)" to the calling terminal (Caller A) 30 through the calling soft switch 20 (1334). In response, the originating terminal 30 transmits an "ACK" message confirming that the message has been received to the originating application server 11 through the originating soft switch 20 (1335), and the originating application server 11 sends an "ACK" message. Message is transmitted to the secondary terminating terminal (30, 60, 80) via the exchange (50, 70) or the terminating soft switch (20) via the outgoing soft switch (1336).

As a result, a voice or video RTP channel (voice call or video call) is formed between the calling terminal 30 and the second called terminal 30, 60, and 80 to make a voice or video call between the calling party and the called party (1337). .

14 is a view illustrating a procedure of scraping image information (/ subtitle information) to a called-party video telephone and using an additional service of scrap image information (/ subtitle information) in a video information scrap service and an additional service method according to the present invention; It is a flow chart.

As described above, according to the embodiments 1-1 to 1-4, during the voice call between the calling / calling terminal, one terminal connected to the media server 13 through the video channel (assuming the called terminal, It has been suggested that image information (which may include subtitle information) or location-based image information (which may include subtitle information) may be provided as a "first called terminal." In this case, a voice channel is connected between the calling / calling terminal (1401), and transmits the video channel information of the media server 13 to one terminal (called terminal) of the calling / calling terminal to the media server 13 and one terminal ( The video channel is connected between the primary destination terminal (1402).

However, according to the embodiments 1-5 to 1-8, subtitle information or location-based caption information may be provided to one terminal (assuming the primary destination terminal) during a video call between the calling / calling terminals. have. In this case, although not shown in the figure, voice and video channels are connected between the calling / called terminal.

Therefore, the video information / subtitle information is continuously displayed on the screen of one terminal (assuming the primary receiving terminal) [video telephone 30] among the calling / calling terminals in the voice or video call (eg As shown in FIG. 15, the image information 15a, 15b, and 15c are sequentially shown.

If the user (recipient) presses a scrap input signal (expression of scraping on the currently viewed video information / subtitle information) to scrap the video information / advertisement information provided during a call, the corresponding information (scrap request information) Is transmitted to the destination application server (tAS) 11 via the incoming soft switch (tSSW) 20 via the INFO message [INFO (Scrap Now)] 1403. At this time, the incoming soft switch 20 recognizes the scrap request information through the received INFO message, and delivers an INFO (Scrap Now) message to the destination application server 11.

Accordingly, the incoming application server 11 sends the video information / subtitle information scrap to the video information management server (subtitle information management server) 12 based on the telephone number and IP address of the called terminal (Callee B) 30. In response to the request (1404), a response code is received from the video information management server (subtitle information management server) 12 (1405). At this time, the incoming application server 11 transmits a message requesting to scrap the video information / subtitle information currently being played to the video information management server (subtitle information management server) 12 together with the phone number and IP address. The video information management server (subtitle information management server) 12 stores the scrap image information / subtitle information in the scrap DB 125 for each user based on the telephone number and the IP address. In addition, the terminating application server 11 transmits a "200 OK" message to the primary terminating terminal 30 through the terminating soft switch 20 in response to the INFO message from the primary terminating terminal 30 (1406). ).

Steps 1403 to 1406 may be repeatedly performed during a call, and a user (called party) may selectively scrape desired information from the image information / subtitle information provided during the call.

As described above, the caller A (Caller A) (30, 60, 80) and the caller (Callee B) 30 is in a voice or video call state, the call is terminated normally through a message transfer when a call termination request is received from one side (1407-1412).

That is, as an example, when the call is terminated by the calling terminal 30, 60, 80, the calling terminal 30 is the destination application server 11 through the switch 50, 70 or the calling soft switch 20 Send a call termination (BYE) message (1407), and the terminating application server 11 sends the " BYE " message again via the exchange 50 or 70 or the outgoing soft switch 20 (tSSW). The call is sent to the primary called terminal (Callee B) 30 through 20 to terminate the call (1408, 1409). In response, the primary terminating terminal 30 transmits a "200 OK" message in response to the exchange 50 or 70 or the originating soft switch 20 via the terminating soft switch 20 (1410). 50, 70 or the outgoing soft switch 20 relays a "200 OK" message to the destination application server 11 (1411), and the destination application server 11 again switches to the exchange 50, 70 or outgoing soft switch ( 20, and transmits the message "200 OK" to the calling terminal (30, 60, 80) (1412). At this time, the originating terminal (30, 60, 80) transmits an "ACK" message confirming that the message has been received to the destination application server 11 through the switch (50, 70) or the originating soft switch 20, The call is terminated between the called terminals (1413).

Thereafter, after the call ends, when the primary terminating terminal 30 presses an automatic connection or a specific access code according to a setting to view the scraped image information / subtitle information, the primary terminating terminal 30 is directed to the terminating soft switch 20. The INVITE message is transmitted [INVITE (offer SDP B)], and the incoming soft switch 20 recognizes the subscriber's connection request to the scrap image information / subtitle information through the service code in the message and then sends the INVITE to the incoming application server 11. Send a message (1414).

Then, the destination application server 11 loads the VoiceXML document URL in the INFO message [INVITE (offer SDP B)] and sends it to the media server 13 to request a connection for the scrap image information / subtitle information (1415). In response, the media server 13 sends a message "200 OK (answer SDP MS)" to the destination application server 11 in response to the "INFO" message (1416), and the destination application server 11 sends the message. The message “ACK” is sent to the media server 13 acknowledging receipt (1417). The destination application server 11 transmits a "200 OK (answer SDP MS)" message to the destination terminal 30 through the destination soft switch 20 in response to the message "INVITE" of the destination terminal 30. In operation 1418, the destination terminal 30 transmits an "ACK" message to the destination application server 11 through the destination soft switch 20 confirming that the message has been received (1419).

After that, when the "ACK" message is received from the called terminal 30, the called application server 11 carries the VoiceXML URL information necessary for providing the scrap menu to the "INFO" message to the media server 13 (1420). The media server 13 forwards the message "200 OK" to the destination application server 11 in response to the "INFO" message (1421), and the destination application server 11 confirms that the message has been received. Message is sent to the media server 13 (1422). The media server 13 extracts the VoiceXML document URL information from the received INFO message and transmits the VoiceXML document URL to the video information management server (subtitle information management server) 12 using HTTP to execute the service script. (1423). That is, an HTTP request message is created with the VoiceXML document URL value and transmitted to the video information management server (subtitle information management server) 12 to request the VoiceXML document.

Subsequently, when a VoiceXML document (sound file and video file), which is a service script, is received in response to the HTTP request message from the video information management server (subtitle information management server) 12 (1424), the media server 13 receives the media server 13. The image file (menu-selected scrap image information / subtitle information screen) and the sound source file generated by parsing, interpreting and executing the voiceXML document are transmitted to the primary terminating terminal 30 through a real-time transmission protocol (RTP) (1425). .

At this time, when the menu-selected scrap image information / subtitle information screen and the announcement broadcast transmitted through the real-time transmission protocol (RTP) are delivered to the user (the called party), the media server 13 manages the called party and the image information management server (subtitle information management). The interaction between the server) 12 is relayed (1425). Looking at this in detail.

Menu-selected scrap image information / subtitle information screen reproduced in the videophone 30 via a real-time transmission protocol (RTP) [for example, '1. Car advertising ',' 2. Chicken advertising ',' 3. Through the scrap list of movie advertisements] and announcements, when a user (recipient) who wants to use the supplementary service looks at the menu image and presses the menu number [for example, in the scrap list, '1. Car advertisement '], and the media server 13 receiving the menu number through the real-time transmission protocol (RTP) displays the menu number of the additional service that the caller wants through the DTMF signal extraction process through the VoiceXML script interaction process. The information management server (subtitle information management server) 12, and the image information management server (subtitle information management server) 12 for this, the menu number determined by the called back function, the detailed information view function, telephone connection Corresponding VoiceXML document for function [For example, if No. 1 is selected, the submenu as' 1. Watch again ',' 2. Detailed description (price, etc.) ',' 3. Menu selection screens such as 'calling consultation' and 'returning to the previous menu'] are transmitted to the media server 13 through the HTTP protocol, and the media server 13 interprets the VoiceXML document to select menu-type scrap image information / The caption information screen and the sound source file are transmitted to the called terminal (video phone) 30.

In this relay process 1425, the receiver presses a menu number (for example, replay selection, detail view selection, and telephone connection selection) at which the menu selection scrap image information / subtitle information screen selection process can be terminated. It is repeated until the final VoiceXML document is received from the (caption information management server) 12. That is, if the final VoiceXML document is not received, the step of continuously receiving the menu number from the called party is performed. This assumes that the replay feature, the details view feature, and in particular the telephony feature, are in the final VoiceXML document (submenu).

If the called party presses a menu number (for example, selecting to make a telephone call) where the menu selection type scrap image information / subtitle information screen selection process can be terminated, the media server 13 connects the incoming call of the corresponding VoiceXML document. The telephone number is obtained from the video information management server (subtitle information management server) 12, and a session control request message to which the incoming connection telephone number is added is sent to the terminating application server 11 (1426). The receiving application server 11 receives the session control response message to the media server 13 (1427), and sends the session start request message (INVITE message) to the incoming soft switch 20 or the exchange 50 or 70. Through the transmission to the telephone (secondary destination terminal) (30, 60, 80) of the final destination (1428).

Subsequently, the secondary destination terminal (Callee C) 30, 60, 80, which is the final destination telephone, sends a session initiation in progress message (180 Ring message) to the exchange 50, 70 or the session initiation request message (INVITE message). Transmit to the incoming application server 11 through the incoming soft switch 20 (1429), the destination application server 11 renegotiates the media information through the "RE-INVITE" message for the ring back tone processing (1430,1431) ). That is, the terminating application server 11 receives a "RE-INVITE (no SDP)" message without SDP information for processing the ring back tone through the terminating soft switch 20 or the exchange 50 or 70. Telephone) (now the primary called terminal becomes the calling terminal) 30 (1430), and the primary called terminal (i.e., the calling terminal) 30 sets the SDP of the calling terminal to " 200 " The message "OK (offer SDP A)" is transmitted to the destination application server 11 through the exchange 50 or 70 or the incoming soft switch (which becomes the outgoing soft switch) (1431).

When the called party rings and the last called party (e.g., an agent) receives a call (hook-off) to answer the call, a session start response message (200 OK message) passes through the soft switch 20 to the application server ( 11) (1333). That is, the secondary called terminal (Callee C) 30, 60, 80 sets the SDP of the called terminal and sends a "200 OK (SDP C)" message through the switch 50, 70 or the called soft switch 20. The call is sent to the destination application server 11.

Then, the destination application server 11 transmits the message "200 OK (SDP C)" to the primary destination terminal (calling terminal) 30 again through the exchange 50 or 70 or the incoming soft switch 20 ( 1434). In response to this, the primary called terminal (sending terminal) 30 transmits an " ACK " message confirming that the message has been received to the called application server 11 through the switch 50, 70 or the called soft switch 20. 1435, the terminating application server 11 transmits the " ACK " message to the secondary terminating terminal 30,60,80 through the exchange 50,70 or the terminating soft switch 20 (1436).

Thus, a voice or video RTP channel (voice call or video call) is formed between the primary called terminal (sending terminal) 30 and the secondary called terminals 30, 60, and 80, so that voice or A video call is made (1437).

FIG. 11 is a flowchart illustrating a video information service process and a scrap service process for a video information scrap service and an additional service according to the present invention, in providing video information (including subtitle information) to a caller and / or a called party; , Subscription information of the service subscriber, for example, broadcast type video information, customized image information, call type video information, location based type video information (location based type broadcasting video information, location based type customized video information, location type calling type) Based on which image information is desired to be serviced, the procedure for providing the corresponding image information will be described. Then, the video information / subtitle information scrap service function that can scrape the video information / subtitle information during the voice or video call.

The video information service may include a video telephone (SIP video terminal) 30 and a voice-only telephone (that is, 'support only voice without video' (eg, 2G mobile communication terminal, PSTN voice telephone, etc.), or 'video'. Voice call phone] (eg, SIP / H.323 / H.324 videophone, 3G mobile terminal, etc.) During a voice call or during a video call between a video phone (SIP video terminal) 30 and a video phone (video phone supporting video and set to a video mode, 3G mobile communication terminal, etc.) 30,60 Set broadcast type video information (/ caption information), call type video information (/ caption information), customized video information (/ caption information), location-based video information (/ caption information) [For example, location-based broadcasting Type video information (/ caption information), location-based call type video information (/ caption information), location-based customized Video information (/ caption information)] on the subscriber's video phone screen [in this case, broadcast type video information (/ caption information), customized video information (/ caption information), location-based broadcast video information (/ caption) Information), providing location-based customized video information (/ subtitle information)], and providing it to the counterpart's video phone screen (in this case, call-type video information (/ caption information) and location-based call video information (/ caption information) )].

Therefore, when video information (/ subtitle information) can be provided, when a call connection attempt is made from a video telephone (calling terminal) 30 to a voice-only telephone (calling terminal) 30, 60, 80, or voice only When a call is attempted from the telephone (calling terminal) 30, 60, 80 to the video telephone (called terminal) 30, the video telephone (calling terminal) 30, 60 is a video telephone (called terminal) (30, 60). ) Can be divided into three cases when attempting a call connection.

Therefore, when the calling terminal attempts to connect to the called terminal (delivering an INVITE message as a dialing signal) (1101), the soft switch 20 determines whether the user of the calling / called terminal is the subscriber of the video information service (1102). )). Of course, as described above, the soft switch 20 forwards the INVITE message received from the calling terminal to the application server 11 through the intelligent network when the voice call connection request or the video call connection request is included in the INVITE message. Based on the caller information and the called party information, it is possible to inquire whether or not to subscribe to the service and perform the call processing procedure according to the result of the inquiry.

As a result of determination 1102, when the user of the calling / called terminal is not a subscriber of the video information service, the soft switch 20 performs a voice call or a video call procedure between the calling / called terminals according to a general call processing procedure ( 1103).

As a result of the determination 1102, when the user of the calling / receiving terminal is a video information service subscriber, the soft switch 20 transmits the corresponding information to the application server 11 of the video information providing apparatus 10, and the application server ( 11) classifies video information (/ subtitle information) to be provided according to the service subscription type of the calling / called terminal user (video information service subscriber).

If the calling / incoming video information service subscriber is the subscriber of the call type video information (/ caption information) service (1104), the application server 11 determines whether the call type video information (/ caption information) is set based on the location. In step 1105, the call-type video information (/ subtitle information) subscriber or the location-based call-type video information (/ subtitle information) subscriber is set (1106, 1107).

On the other hand, when the calling / incoming video information service subscriber is a customized video information (/ subtitle information) service subscriber (1108), the application server 11 determines whether the customized video information (/ subtitle information) is set based on location. (1109), it is set as the customized image information (/ caption information) subscriber or the location-based customized image information (/ caption information) subscriber (1110, 1111).

On the other hand, when the calling / incoming video information service subscriber is not a subscriber of the call-type video information (/ subtitle information) service and the customized video information (/ subtitle information) service subscriber (1108), the application server 11 is broadcast type. It is regarded as a subscriber of video information (/ subtitle information). In this case, since the broadcast type video information (/ caption information) can be provided based on location (1112), the broadcast type video information (/ caption information) subscriber or the location-based broadcast video information (/ caption information) subscriber is set. (1113,1114).

Subsequently, the application server 11 transmits the image information providing form and content type information (call-type image information (/ caption information), customized image information (/ caption information), broadcast type to the media server 13). Video information (/ caption information), location-based call-type video information (/ caption information), location-based customized video information (/ caption information), location-based broadcast video information (/ caption information)], The media server 13 provides corresponding image information (/ subtitle information) to the calling / calling terminal based on the image information providing form and content type information transmitted from the application server 11 (1115).

Then, the application server 11 continuously monitors whether the voice call or the video call between the calling / called terminal is terminated (1116), and when the voice call or the video call between the calling / called terminal is terminated, the application server 11 receives the media. The server 13 transmits a signal to stop providing image information (/ subtitle information) to the calling / calling terminal (1117), and thus the media server 13 stops providing image information (/ subtitle information). (1118).

In particular, when video information / subtitle information is sequentially displayed on the screen of the calling or receiving terminal (video phone) 30 during a voice or video call, the user (sender or called party) receives the video information / advertisement information provided during the call. Can scrap. In other words, when a scrap input signal (speech expression that you want to scrap with respect to the currently viewed video information / subtitle information) is pressed during an audio or video call, the corresponding information (scrap request information) is applied through the soft switch 20 through the INFO message. The server 11 transmits a message to the video information management server (subtitle information management server) 12 to transmit a message requesting to scrap the video information / subtitle information that is currently being played (1119). By transmitting along with the IP address, the video information management server (caption information management server) 12 stores the scrap image information / subtitle information in the scrap DB 125 for each user based on the telephone number and the IP address (1120). .

The video information / subtitle information scrap service function may be repeatedly performed during a call, and the user (sender) may selectively scrap desired information from the video information / subtitle information provided during the call.

Thereafter, after the call ends, the user presses an automatic connection or a specific access code to select a menu-selectable scrap image information / caption information screen [for example, '1. Car advertising ',' 2. Chicken advertising ',' 3. [Scrap list of movie advertisements]] (15d of FIG. 15), a menu number may be selected, and an additional service of corresponding video information / subtitle information may be used (for example, '1. Watch again ',' 2. Detailed description (price, etc.) ',' 3. Call, etc. '(15e in Fig. 15).

On the other hand, the method of the present invention as described above can be written in a computer program. And the code and code segments constituting the program can be easily inferred by a computer programmer in the art. In addition, the written program is stored in a computer-readable recording medium (information storage medium), and read and executed by a computer to implement the method of the present invention.
