BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for providing video information on a video phone screen during a call and a method of displaying video information on the screen,

The present invention relates to an apparatus and method for providing image information on a video telephone screen during a call, and more particularly, to a video telephone system in which a video phone user connects a video channel of a video telephone with a media server during a voice call, The present invention relates to a video information service apparatus and a method thereof, which enable video information provided by a media server to be viewed while making a voice call with the other party.

In addition, the present invention relates to a video information service apparatus and a video information service method for enabling a video phone user to view a caption information while making a video call with the other party in a video call with a user of another video phone.

The present invention also provides a method and apparatus for providing image information / caption information suitable for users' tastes (currency, custom, broadcast type, location-based type, etc.) , An image information service apparatus and a method thereof.

The present invention transmits video information (including caption information) to a video telephone of one side during a voice call. In response to this, an IP-based video telephone (multimedia terminal or video terminal) to be used in one video telephone (Internet or broadband convergence network (BcN: Broadband convergence Network) environment) (Or a voice telephone) is a system that supports 'video only but not audio' (for example, a 2G mobile communication terminal, a PSTN (public switched telephone network) voice telephone or the like) (E.g., a SIP / H.323 / H.324 video phone, a 3G mobile communication terminal, etc.) that is set to voice mode and does not want to make a call.

In addition, the present invention transmits caption information to a video telephone on one side during a video call. In response to this, the 'video telephone' of the other side of the video call with the video telephone of one side is also connected to the 'video telephone set supporting the video and set to the video mode (for example, SIP / H.323 / H.324 video phone, Etc.).

The form of providing the 'video information' to be provided in the voice communication may be provided as pure video information with no sound due to the nature of the enterprise advertisement / publicity, other information (life, area, hobby, Can be provided with. In addition, the form of providing the 'caption information' provided in the video call can be provided as corporate advertisement / publicity, other information (life, area, hobby, news, weather, etc.).

Here, it is preferable that the pure video information is provided as a video telephone during a voice call during a video phone and a voice call. However, the caption information may be provided to the video phone along with the other party video during the video call during the video phone call and the video phone call, or may be provided together with the pure video information through the video phone during the voice call during the video phone and voice call desirable. In particular, pure video information and caption information can provide location based information.

Here, the content type of the 'video information / caption information' includes the currency type video information / caption information provided by the communicating party, own attributes (eg, assumption, SOHO) and time Customized video information / caption information provided by selecting an area of interest (eg, holiday, entrance, graduation, etc.), or a field of interest The broadcast-type image information / caption information provided to the user, and the location-based image information / caption information providing the local advertisement / promotion based on the location. However, the location-based image information / caption information may be provided together with broadcasting type image information / caption information, currency image information / caption information, and custom image information / caption information. That is, the location-based image information / caption information may be location-based broadcast image information / caption information, location based currency image information / caption information, and location-based custom image information / caption information.

Hereinafter, when the video information and the subtitle information are not distinguished from each other, the video information should be interpreted as a concept including pure video information and subtitle information.

Although voice-oriented services have been provided in the conventional telephone network (PSTN) and mobile communication network, IP-based video telephones and video call phones that have been popular in recent years are not limited to voice but multimedia services including video and data as main services to provide.

Unlike voice telephony service, video telephony service can provide video information on the screen, and the characteristics of this video provision can be said to be very effective in terms of utilization, scalability, and communication.

Normally, in a video telephone service, channel information such as a video / audio codec and an IP (Internet Protocol) address and port of a channel are exchanged while a call is connected. When the call connection process ends, the call is made by transmitting the media packet of the video / audio to the channel of the other party. This process will be described in more detail with reference to FIGS. 1 to 3. FIG.

In Fig. 1, the calling side is a video telephone, and in Fig. 2, the called side is a video telephone. And FIG. 3 shows a video call procedure when both sides are video telephones.

1, when the calling party is the video telephone A and the called party is the voice-only telephone B, the video telephone A transmits its voice channel and video channel information to the soft switch SSW Only the voice channel information is transmitted to the voice-only telephone set B via the soft switch SSW, so that the voice-only telephone set B does not support the video. Only a voice call is made.

On the other hand, as shown in Fig. 2, when the calling party is the voice-only telephone set A and the called party is the video telephone B, since the voice-only telephone set A does not support the video, The video telephone B transmits the voice channel and (video channel) information thereof to the voice telephone A via the soft switch SSW when the voice telephone B accepts the call connection request, / Only the voice call is made between the incoming phone.

In the case where the called party is a video phone, since there is no video channel information at the call connection request from the calling party, even if the called party supports the video, the video information is included in the response to the call request It may not. These items are shown in parentheses for image information.

1 and 2, the voice-only telephone corresponds to a PSTN telephone / 2G mobile communication terminal. However, since the PSTN telephone / 2G mobile communication terminal can not be directly connected to the IP network, a gateway that mediates connection with the IP network should be used. Therefore, in FIG. 1 and FIG. 2, when the voice-only telephone is a PSTN telephone / 2G mobile communication terminal, it includes a gateway for mediating connection with the IP network.

In the current video telephone service, since the video telephone has not been widely used yet, even if the video telephone is used, as mentioned in FIG. 1 and FIG. 2, the user speaks with the voice only telephone supporting voice only like the PSTN telephone / 2G mobile communication terminal There are many cases.

However, there is a problem that the screen display device of the video telephone is not used for a call when talking to a voice-only telephone that supports only voice, so that the screen display device is not used during voice call. Of course, while the video phone itself displays the user's own screen during a voice call, this is merely a means of temporarily filling the screen, but it is by no means sufficient to fully utilize the video phone as a multimedia medium. Therefore, according to the configurations of FIGS. 1 and 2, the video call advertisement service is impossible.

On the other hand, as shown in FIG. 3, in a basic video telephone service, the terminal-to-terminal connection method is used based on the concept of a call service.

3, when the calling party and the called party are video telephones, the calling video telephone A transmits its voice channel and video channel information to the called video telephone through the soft switch (SSW) B, and in response to the call connection request, the destination video phone B responds to the originating video phone A via the soft switch SSW with its own voice channel and video channel information, A video call is made.

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

However, since a video channel and a voice channel are created between the source video phone A and the destination video phone B in FIG. 3, the third device is interposed in such a manner and the service can not be extended by providing various contents .

That is, as described above with reference to FIG. 3, if a video telephone service is configured only by connecting a video / audio channel to one counterpart telephone at the same time, flexibility of separating a video channel and a voice channel from a video telephone service Making it difficult to create various additional / application services. Therefore, according to the configuration of FIG. 3, the video call advertisement service is impossible.

On the other hand, the voice call advertisement service in the existing PSTN or the like causes the inconvenience to the users because the voice call announcement service proceeds to hear the advertisement in advance in the form of a voice message, and the user has to spend extra time. Also, the provided advertisement does not reflect the taste of the user and provides the advertisement indiscreetly. Therefore, there is a limit in implementing a video call advertisement service by introducing a voice call advertisement service into a video call service.

Therefore, there is an urgent need for a new video call advertisement service suitable for the video telephone service. Therefore, if it is possible to provide useful information or advertisement together with a voice or video call while reflecting the characteristics of the video phone (utilizing a screen display device of a video phone which is not used during a voice call), it will be more useful for a video phone service It is expected. In addition, by providing video information suitable for users' taste (call type, customized, broadcast type, location based type, etc.) during voice or video call, it is possible to improve the satisfaction of video phone users and utilization of video telephony, It is expected that it will be able to generate various revenue by expanding the advertisement market.

Accordingly, in the present invention, the video channel of the video phone is connected to the media server during the voice call so that the video phone user can view the video information provided by the media server while making a voice call with the other party, And to provide a video information service apparatus and method therefor.

Another object of the present invention is to allow a user of a one-way telephone to make a video call with a user of another video telephone while viewing a video call with the other party.

At this time, the other party's phone (called terminal) 30, 60, 80 that makes a voice call with the calling service subscriber video phone (calling terminal) 30 is a voice-only telephone (i.e., (For example, a SIP / H.323 / H.324 video phone, a 3G mobile phone, a PSTN voice phone, etc.) or a ' Mobile communication terminal, etc.) voice call telephone] is sufficient.

In the case of the call type video information or the location-based call type video information, the pure video information set by the called service subscriber during the voice call is provided to the video telephone (calling terminal) 30 of the other party Can include caption information]. At this time, the telephone (receiving terminal) 30, 60, 80 of the service subscriber who makes a voice call with the video telephone (calling terminal) 30 of the other party may be a voice-only telephone.

7, the calling terminal (video phone) 30 attempts to make a call to any of the called terminals 30, 60, and 80 and transmits the call to the calling terminal 30 The calling soft switch 20 sets the SDP (Session Description Protocol) of the calling terminal (Caller A) to the calling soft switch (oSSW) 20 and sends an INVITE message (offer SDP A) (E.g., SIP video terminal identification information (telephone number, device number, IP address, MAC address, etc.)) as a code, recognizes that the caller is a video information service subscriber and sends an INVITE message (offer SDP A) (701). This corresponds to a case where the subscriber of the video information service originating service selects one of broadcasting type video information, customized video information, location based video information (e.g., location based broadcast type video information, location based customized video information). However, if the subscriber selects the call-type video information or the location-based call-type video information, the calling soft switch 20 checks the service code in the INVITE message and recognizes that the called party is a video information service subscriber.

Of course, in order to enable the outgoing soft switch 20 to smoothly perform the SIP call connection function in the intelligent network, the outgoing soft switch 20 requests connection from the calling terminal (video phone) 30 to the voice call via the INVITE message (Video phone) 30 to the service of the originating application server 11 so as to inquire the service of the calling terminal (video phone) 30 to follow the call processing procedure of the corresponding subscription service, for example, the video information service It may forward the call to the originating application server 11.

The originating application server 11 sends an INVITE message (offer SDP A) back to the originating softswitch 20 (702) and the originating softswitch 20 receives the originating terminal (Callee B) 30,60,80 703 to the place where the mobile terminal 100 is located, via the exchange 50, 70 or the incoming soft switch tSSW 20. Then, the callee B 30, 60, 80 transmits a 180 Ring message to the exchange 50, 70 or the incoming soft switch tSSW 20 (20) in response to the INVITE message (offer SDP A) The originating soft switch 20 sends a 180 Ring message to the originating application server 11 and relays 705 the originating application switch 11 to the originating application server 11 Transmits a 180 Ring message to the calling terminal (video phone) 30 via the outgoing soft switch 20 to inform the call waiting (706).

Thereafter, when the called party answers and the called party answers (Hook-off), the called terminal (Callee B) 30, 60, 80 responds with voice only because it is set to voice mode or does not support video, At this time, the 200 OK message is used (707). That is, the call terminals (Callee B) 30, 60, 80 set the SDP of the called terminal and send a message "200 OK (answer SDP B)" to the exchange 50, 70 or the incoming soft switch (tSSW) The originating soft switch 20 passes the message "200 OK (answer SDP B)" to the originating application server 11 (708) (Answer SDP B) message to the calling terminal (video phone) 30 via the calling soft switch 20 (709). In response, 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-only telephone) 30, 60, 80 via the exchange soft switch 20 via the exchange 50, 70 or the incoming soft switch tSSW 20 (713). At this time, the message "ACK" is for informing that a voice call (voice channel) is opened.

In the above, the source application server 11 transmits a "200 OK (answer SDP B)" message to the calling terminal (video phone) 30 (709) In transmitting the "ACK" message to the destination terminals (voice-only telephones) 30, 60, 80 (711, 713), the source application server 11 transmits the source number (or the IP address of the source terminal (For example, the same code) from the location information management server 15 (712), by inquiring the location information management server 15 on the basis of the location code (address). That is, acquisition of location information may be acquired before the "ACK" message is transmitted to the called terminal (voice-only telephone) 30, 60, or 80. This process is for location based image information (e.g., location based broadcast image information, location based currency image information, location based custom image information).

Thereafter, a voice RTP channel (voice call) is established between the calling terminal (video phone) 30 and the called terminal (voice dedicated phone) 30, 60, 80, and voice communication is performed between the calling party and the called party 714.

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

Thereafter, the source application server 11 transmits the SDP information of the calling terminal (video phone) 30 to the media server 13 in the new INVITE message (offer SDP video A) and sends it to the media server 13 (717) , The media server (MS) 13 responds 718 to the sending application server 11 via the message "200 OK (answer SDP video MS)" In response, the source application server 11 transmits an ACK message to the media server 13 (719) and sends an ACK message in response to the "200 OK" message from the calling terminal (video phone) And transmits the message to the calling terminal (video phone) 30 via the outgoing soft switch 20 to re-negotiate the video SDP (720).

When the negotiation is completed, the source application server 11 transmits the video information to be reproduced (for example, broadcasting type video information, currency type video information, customized video information, location-based video information (721), the media server 13 sends an ID or VXML-URL address of the video-type image information, location-based custom image information, etc. to the media server 13 in the "INFO" 200 OK "message to the originating application server 11 in response to the " INFO" message (722). When receiving the ID, the media server 13 queries the content DB 14 to fetch the corresponding video information and reproduce the video information through the video RTP channel (video call) to the calling terminal (video phone) 30 (step 725). If the VXML URL information is received, the media server 13 requests the video information management server 12 for the corresponding video information, fetches the corresponding video information, and transmits the video information to the calling terminal (video phone) through the video RTP channel (video call) (723 to 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 via HTTP, and obtains the video information and reproduces the video information through the video channel.

At this time, it is possible to provide pure video information composed of only video and provide the subtitle information together with pure video information. As described above, it is possible to independently provide broadcast-type video information (including caption information), currency-type video information (including caption information), and customized video information (including caption information) Type video information (including caption information), currency-based video information (including caption information) based on the position, and customized video information based on the position (caption information may be included).

8 is a flowchart illustrating a procedure of providing image information to a destination video phone during a voice call in the video information service method according to the present invention.

In FIG. 8, the video phone 30 of the called service subscriber can receive pure video information (e.g., broadcasting type video information, customized video information, location-based video information (location-based broadcasting type video information, Video information)], etc. [It is possible to include caption information when providing pure video information]. At this time, the telephone (calling terminal) 30, 60, 80 of the other party making a voice communication with the incoming service subscriber video telephone (the call receiving terminal) 30 can receive the voice only telephone (i.e., (For example, a SIP / H.323 / H.324 video phone, a 3G mobile phone, a PSTN voice phone, etc.) or a ' Mobile communication terminal, etc.) voice call telephone] is sufficient.

In the case of currency-type video information or location-based currency-type video information, pure video information set by the calling service subscriber during voice communication is provided to the video phone (called terminal) 30 of the other party ≪ RTI ID = 0.0 > 8) < / RTI > At this time, the telephones (incoming terminals) 30, 60, and 80 of the service subscribers who make a voice call with the video telephone (called terminal) 30 of the other party may be voice only telephones.

8, an arbitrary calling terminal (voice-only telephone) 30, 60, or 80 attempts to call the called terminal (video telephone) 30 and sends a call to the calling terminal (caller A) 30 The originating terminal sets the SDP of the calling terminal (caller A) to the voice switch or the outgoing soft switch (oSSW) 20 The exchange 50 or 70 or the originating soft switch 20 transmits the service code (for example, the SIP video terminal identification information (telephone number, device number, etc.) in the received INVITE message, IP address, MAC address, and the like), recognizes that the called party is a video information service subscriber, and transmits an INVITE message (offer SDP A) to the called soft switch (tSSW) 20 at the location of the called terminal (Callee B) (801). In response, the inbound soft switch 20 delivers an INVITE message (offer SDP A) to the incoming application server (tAS) 11 (802). This corresponds to the case where the subscriber of the video information service originating service selects one of broadcasting type video information, customized video information, location based video information (location based broadcasting type video information, location based customized video information). However, when the subscriber selects the call-type video information or the call-based video information based on the location, the in-coming soft switch 20 checks the service code in the INVITE message to recognize that the caller is a video information service subscriber.

Of course, in order to allow the incoming soft switch 20 to smoothly perform the SIP call connection function in the intelligent network, the incoming soft switch 20 receives the INVITE message from the calling terminal (voice dedicated telephone) 30, 60, When receiving a connection request by voice call, the INVITE message is forwarded to the destination application server 11 to inquire which service the subscriber terminal (video phone) 30 is subscribed to, It may pass the call to the terminating application server 11 to follow the processing procedure.

The incoming softswitch 20 sends an INVITE message (offer SDP A) to the called soft switch 20 and the incoming soft switch 20 sends an INVITE message (offer SDP A) to the called terminal (video phone) A) (803). Then, the called terminal (video phone) 30 sends a 180 Ring message to the incoming application server 11 via the incoming soft switch tSSW 20 in response to the INVITE message (offer SDP A) The incoming application server 11 transmits a 180 Ring message to the incoming soft switch 20 in step 805 and the incoming soft switch 20 sends a 180 Ring message again (Voice-only telephones) 30, 60, and 80 through the exchanges 50 and 70 or the outgoing soft switch 20 to notify the call waiting (806).

When the called party rings and the called party answers (Hook-off), the called terminal (video phone) 30 responds to the video only because the terminal supports the video. At this time, the 200 OK message is used (807). That is, the callee B 30 sets the SDP of the called terminal and transmits a message "200 OK (answer SDP B)" to the calling incoming application server 11 via the incoming soft switch (tSSW) The incoming application server 11 transmits a message "200 OK (answer SDP B)" to the incoming soft switch 20 (808), and the incoming soft switch 20 returns to the exchanger 50, (Answer SDP B) "message to the calling terminal (voice-only telephone) 30, 60, 80 via the calling soft switch 20 (809). On the other hand, the calling terminal (voice-only telephone) 30, 60, 80 transmits an "ACK" message confirming that the message has been received to the incoming soft switch 20 (811), and the called application server 11 transmits an "ACK" message to the called terminal (video phone) 30 via the incoming soft switch 20 (813 ). At this time, the message "ACK" is for informing that a voice call (voice channel) is opened.

The incoming application server 11 transmits a "200 OK (answer SDP B)" message (808, 809) to the calling terminal (voice dedicated telephone) 30, 60, (811, 813) to the destination terminal (video phone) 30, the destination application server 11 transmits the "ACK" message from the destination terminal 30, 60, The IP address of the called terminal) to the location information management server 15 (810) and receives the corresponding area code (e.g., code) from the location information management server 15 (812) ). That is, acquisition of the location information may be acquired before the "ACK" message is transmitted to the destination terminal (video phone) This process is for location based image information (location based broadcast image information, location based currency image information, location based custom image information).

Thereafter, a voice RTP channel (voice call) is established between the calling terminal (voice-only phone) 30, 60, 80 and the called terminal (video phone) 30 to make a voice communication between the calling party and the called party 814.

During the voice call, the incoming application server 11 transmits a "RE-INVITE (no SDP)" message without SDP information to the called terminal (video phone) 30 via the incoming soft switch 20 (815). In response, the destination terminal (video phone) 30 sets the SDP of the destination terminal and transfers the message "200 OK (offer SDP B)" to the destination application server 11 via the destination soft switch 20 (816 ).

The incoming application server 11 transmits the SDP information of the called terminal (video phone) 30 to the media server 13 in a new INVITE message (offer SDP video B) , The media server (MS) 13 responds 818 the SDP information of the media server to the receiving application server 11 via the message " 200 OK (answer SDP video MS) ". In response, the terminating application server 11 transmits an "ACK" message to the media server 13 (819) and transmits an "ACK" message in response to the "200 OK" message from the called terminal (video phone) And transmits the message to the called terminal (video phone) 30 through the incoming soft switch 20 to re-negotiate the video SDP (820).

Upon completion of the negotiation, the incoming application server 11 transmits the video information to be reproduced (for example, broadcasting type video information, currency type video information, customized video information, location-based video information (E.g., currency type video information, location-based customized video information, etc.) or VXML-URL address in an "INFO" message to the media server 13 (821). In response to this, the media server 13 transmits a "200 OK" message to the receiving application server 11 in response to the "INFO" message (822). If the ID is received, the media server 13 queries the content DB 14 to fetch the corresponding video information and reproduce the video information through a video RTP channel (video call) to the destination terminal (video phone) 30 (825). If the VXML URL information is received, the media server 13 requests the video information management server 12 for the corresponding video information, fetches the corresponding video information, and transmits the video information to the destination terminal (video phone) through a video RTP channel (video call) (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 via HTTP, and obtains the video information and reproduces the video information through the video channel.

At this time, it is possible to provide pure video information composed of only video and provide the subtitle information together with pure video information. As described above, it is possible to independently provide broadcast-type video information (including caption information), currency-type video information (including caption information), and customized video information (including caption information) Type video information (including caption information), currency-based video information (including caption information) based on the position, and customized video information based on the position (caption information may be included).

9 is a flowchart illustrating a procedure of providing video information (/ caption information) to a calling video phone during a video call in the video information service method according to the present invention.

9, the video phone 30 of the originating service subscriber transmits the caption information (e.g., broadcasting type caption information, customized caption information, location-based caption information (location-based broadcast type caption information, Based customized subtitle information)). At this time, the telephone (receiving terminal) 30, 60 of the other party making a video call with the calling service subscriber video telephone (calling terminal) 30 is connected to a video telephone (video telephone, Communication terminals, etc.).

Further, in the case of the currency type caption information or the location-based currency type caption information, the caption information set by the called service subscriber during the video call is provided to the video telephone (calling terminal) 30 of the other party. At this time, the telephones (called terminals) 30 and 60 of the service subscribers who make a video call with the video telephone (calling terminal) 30 of the other party are connected to a video phone (video phone, Communication terminals, etc.).

9, the calling terminal (video phone) 30 first attempts to call any of the called terminals (video telephones) 30 and 60 and sends a call to the calling soft switch the calling soft switch 20 sets the SDP (Session Description Protocol) of the calling terminal (Caller A) to the oSSW 20 and sends an INVITE message (offer SDP A) The SIP server 11 identifies the SIP video terminal identification information (telephone number, device number, IP address, MAC address, etc.)] and recognizes that the caller is a caption information service subscriber. Then, the originating application server oAS 11 transmits an INVITE message A) (901). This corresponds to a case where the subscriber of the caption information service originating service selects one of broadcasting type caption information, customized caption information, location based caption information (location based broadcast type caption information, location based custom caption information). However, when the subscriber selects the call type caption information or the call type caption information based on the location, the calling soft switch 20 confirms the service code in the INVITE message and recognizes that the called party is the caption information service subscriber.

Of course, in the intelligent network, in order for the outgoing soft switch 20 to smoothly perform the SIP call connection function, the outgoing soft switch 20 requests connection from the calling terminal (video phone) 30 to the video call through the INVITE message (Video phone) 30 to the service of the originating application server 11 so as to inquire the service of the calling terminal (video phone) 30 to follow the call processing procedure of the corresponding subscription service, for example, the caption information service in the case of receiving the INVITE message It may forward the call to the originating application server 11.

The originating application server 11 sends an INVITE message (offer SDP A) back to the originating softswitch 20 (902) and the originating softswitch 20 returns to the originating terminal (Callee B) 30,60 And transmits an INVITE message (offer SDP A) via the switch 50 or the incoming soft switch (tSSW) The callee B 30,60 then sends a 180 Ring message to the exchange 50 or the inbound soft switch tSSW 20 in response to the INVITE message (offer SDP A) (904) the originating softswitch 20 and the originating softswitch 20 relays 905 the ringing 180 ring message to the originating application server 11 and the originating application server 11 returns (180 Ring) message to the calling terminal (video phone) 30 through the soft switch 20 to inform the call waiting (906).

When the called party answers and the called party answers (Hook-off), the called terminals (video telephones) 30 and 60 support the video and respond to the video only by the terminal set in the video mode. At this time, OK message is used (907). That is, the call terminals (Callee B) 30 and 60 set the SDP of the called terminal and send a message "200 OK (answer SDP B)" to the caller via the exchange 50 or the incoming soft switch (tSSW) (907) the softswitch 20 and the originating softswitch 20 relays (908) the message "200 OK (answer SDP B)" to the originating application server 11 and the originating application server 11 200 OK (answer SDP B) "message to the calling terminal (video phone) 30 via the outgoing soft switch 20 (909). In response, 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), and the calling application server 11 Transmits the message "ACK" to the destination terminals (video telephones) 30 and 60 via the source soft switch 20 via the exchange 50 or the destination soft switch tSSW 20 (913). At this time, the message "ACK" is for informing that the voice and video RTP call (voice and video channel) is opened.

The source application server 11 transmits a "200 OK (answer SDP B)" message to the calling terminal (video phone) 30 (909) In transmitting the "ACK" message to the destination terminals (video telephones) 30, 60 (911, 913), the source application server 11 transmits the origination number (or the IP address of the originating terminal) (910), and receives a corresponding area code (e.g., code) from the location information management server 15 (912). That is, the acquisition of the positional information may be acquired before the "ACK" message is transmitted to the destination terminals (video telephones) 30 and 60. [ This process is for location-based caption information (location based broadcast type caption information, location based currency type caption information, location based customized caption information).

Thereafter, a voice and video RTP channel (voice call and video call) is formed between the calling terminal (video phone) 30 and the receiving terminal (video phone) 30 and 60 so that voice and video calls between the calling / (914).

Meanwhile, the source application server 11 transmits the subtitle information URL address to the calling terminal (video phone) 30 in the 'INFO' message during the voice and video communication (step 915). In response, 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 dialog with the video information management server (the subtitle information management server) 12 via HTTP in the form of request and response, and fetches the subtitle information corresponding to the subtitle information URL information It is mixed with the other video and reproduced.

At this time, the caption information may independently provide the broadcasting type caption information, the currency type caption information, and the customized caption information together with the counterpart video during the video call, or may include broadcasting-type caption information based on the position, To provide customized caption information based on the caption information.

10 is a flowchart illustrating an exemplary procedure of providing video information (/ caption information) to a destination video phone during a video call in the video information service method according to the present invention.

In FIG. 10, in the video call, the video telephone 30 of the receiving service subscriber transmits the caption information (e.g., broadcasting type caption information, customized caption information, location based caption information (location based broadcast type caption information, Based customized subtitle information)). At this time, the telephone (calling terminal) 30, 60 of the other party making a video call with the incoming service subscriber video telephone (the call receiving terminal) 30 is connected to a video telephone (for example, a video telephone, Communication terminals, etc.).

Also, in the case of the currency type caption information or the location-based currency type caption information, the caption information set by the originating service subscriber during the video call is provided to the video telephone (the call receiving terminal) 30 of the counterpart. At this time, the telephone (calling terminal) 30, 60 of the service subscriber who is in video communication with the video telephone (called terminal) 30 of the other party supports a video telephone (for example, a video telephone, Communication terminals, etc.).

10, an arbitrary calling terminal (video telephone) 30,60 attempts to call the called terminal (video telephone) 30 and the calling terminal 30 (caller A) ) Or an outgoing soft switch (oSSW) 20 to set the SDP of the calling terminal (in this case, the calling terminal supports the video and sets the video mode to the terminal set for video only), the INVITE message the exchange 50 or the outgoing soft switch 20 sends the service code (for example, SIP video terminal identification information (telephone number, device number, IP address, MAC address, etc.) in the received INVITE message) Recognizes that the called party is a caption information service subscriber and transmits an INVITE message (offer SDP A) to the called soft switch (tSSW) 20 at a location where the called terminal (Callee B) 30 exists (1001). In response, the inbound soft switch 20 delivers an INVITE message (offer SDP A) to the incoming application server (tAS) 11 (1002). This corresponds to a case where the subscriber of the caption information service originating service selects one of broadcasting type caption information, customized caption information, location based caption information (location based broadcast type caption information, location based custom caption information). However, if the subscriber selects the call type caption information or the call type caption information based on the location, the incoming soft switch 20 checks the service code in the INVITE message to recognize that the caller is a caption information service subscriber.

Of course, in order for the incoming soft switch 20 to smoothly carry out the SIP call connection function in the intelligent network, the incoming soft switch 20 may transmit a video call through the INVITE message from the calling terminal (video phone) When the connection request is received, the INVITE message is forwarded to the destination application server 11 to inquire which service the subscriber terminal (video phone) 30 is subscribed to and the call processing procedure of the subscription service, for example, the subtitle information service It may forward the call to the terminating application server 11 to follow.

The incoming softswitch 20 sends an INVITE message (offer SDP A) to the called soft switch 20 and the incoming soft switch 20 sends an INVITE message (offer SDP A) to the called terminal (video phone) A) (1003). Then, the called terminal (video phone) 30 sends a 180 Ring message to the incoming application server 11 via the incoming soft switch tSSW 20 in response to the INVITE message (offer SDP A) The incoming application server 11 transmits a 180 Ring message to the incoming soft switch 20 in step 1005 and the incoming soft switch 20 sends a 180 Ring message again (Video telephones) 30 and 60 through the switch 50 or the outgoing soft switch 20 to notify the call waiting (1006).

Then, when the called party rings and the called party answers (Hook-off), the called terminal (video phone) 30 responds with video only because the terminal supports the video, and then uses the 200 OK message (1007). That is, the callee B 30 sets the SDP of the called terminal and transmits a message "200 OK (answer SDP B)" to the calling incoming application server 11 via the incoming soft switch (tSSW) (1007), the terminating application server 11 transfers the message "200 OK (answer SDP B)" to the terminating soft switch 20 (1008), and the terminating soft switch 20 returns the terminating soft switch 20 to the exchanger 50 200 OK (answer SDP B) "message to the calling terminal (video telephone) 30, 60 via the soft switch 20 (1009). In response to this, the calling terminal (video telephone) 30, 60 transmits an "ACK" message confirming that the message has been received to the called application software switch 20 via the exchange 50 or the outgoing soft switch 20, The receiving application server 11 transmits the message "ACK" to the called terminal (video phone) 30 via the incoming soft switch 20 (1013). At this time, the message "ACK" is for informing that the voice and video RTP call (voice and video channel) is opened.

The incoming application server 11 transmits a "200 OK (answer SDP B)" message to the calling terminals (video telephones) 30, 60 (1008, 1009) (1011, 1013) to the destination terminal (video phone) 30, the destination application server 11 transmits the "ACK" message from the destination terminal 30 (E.g., an IP address of the terminal) 1010 to the location information management server 15 (1010), and receives the area code (e.g., code) from the location information management server 15 (1012). That is, acquisition of the location information may be acquired before the "ACK" message is transmitted to the destination terminal (video phone) This process is for location-based caption information (location based broadcast type caption information, location based currency type caption information, location based customized caption information).

Thereafter, voice and video RTP channels (voice call and video call) are formed between the calling terminals (video telephones) 30 and 60 and the called terminal (video phone) 30, so that voice and video calls between the calling / (1014).

Meanwhile, the incoming application server 11 transmits the caption information URL address to the called terminal (video phone) 30 in the "INFO" message during the voice and video call (1015). In response, the destination terminal (video phone) 30 transmits a "200 OK" message to the originating application server 11 in response to the "INFO" message (1016). Then, the called terminal (video phone) 30 forms a dialog with the video information management server (the subtitle information management server) 12 via HTTP in the form of request and response, and fetches the subtitle information corresponding to the subtitle information URL information It is mixed with the other video and reproduced.

At this time, the caption information may independently provide the broadcasting type caption information, the currency type caption information, and the customized caption information, or may provide the broadcasting type caption information based on the location, the currency type caption information based on the location, and the customized caption information based on the location You may.
