In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference numerals in the drawings denote like elements.

1 is a diagram illustrating a network for providing a video call interworking service between a WCDMA terminal and a high speed Internet terminal according to an embodiment of the present invention.

The network shown in FIG. 1 includes a WCDMA terminal 112 and 114, a WCDMA network 120, a video call interworking system 130, a high speed internet network 142, and a high speed internet terminal 152 and 154.

WCDMA terminals 112 and 114 are third generation mobile communication terminals equipped with the 3G.324M protocol. Hereinafter, the WCDMA terminals 112 and 114 are referred to as 3G.324M terminals.

The WCDMA network 120 includes a mobile switching center (MSC) 122, a radio network controller (RNC) 124, a base station 126, and a home location register (HLR) 128. It includes.

The base station 126 performs functions such as baseband signal processing, wired / wireless conversion, and transmission / reception of a wireless signal, and is connected to the WCDMA terminals 112 and 114 through a wireless channel.

The base station controller 124 is located between the base station 126 and the mobile switching center 122 to control and manage one or more base stations, and performs call processing related traffic and signaling, mobility management, and user terminal management.

The home network location register is connected to the mobile network switch 122 to register and manage broadband mobile subscriber information.

The WCDMA network 120 may further include devices other than the above-described mobile network switch 122, the base station controller, the base station 126, and the home network location register.

The high speed internet network 142 includes an ADSL 144 and a VDSL 146.

The high speed Internet terminals 152 and 154 are terminals equipped with the H.323 protocol and are terminals capable of using high speed Internet services through the ADSL 144 or the VDSL 146. High-speed Internet terminals 152 and 154 are hereinafter referred to as H.323 terminals. A representative example of the H.323 terminals 152 and 154 is a personal computer (PC) equipped with the H.323 protocol.

The video call interworking system 130 is disposed between the WCDMA network 120 and the high-speed Internet network 142, the video interlocking device (132), the addresskeeper (134) and the video interlocking subscriber information register. 136.

The video interlocking device 132 performs a call conversion and control protocol conversion function and a media (codec) conversion function between the 3G.324M protocol and the H.323 protocol. The media conversion function refers to a conversion function between different codecs. For example, the 3G.324M terminal implements the AMR (Adaptive Multi-Rate) codec for voice and the H.263 codec for video, and the H.323 terminal (152, 154) implements the G.723.1 codec for voice. Assume that software such as Netmeeting with the H.263 codec is used for video and video. In this case, the video interlocking device 132 converts the AMR and the G.723.1 codec for the audio. If the audio and video codecs are the same between the 3G.324M terminals 112 and 114 and the H.323 terminals 152 and 154, the video interlocking device 132 performs only the protocol conversion function and omits the media conversion function. .

The address translator 134 performs a mutual translation function between an Internet Protocol (IP) address (hereinafter referred to as an IP address) of the H.323 terminals 152 and 154 and an E.164 number. E.164 numbers are a telephone numbering system standardized by the International Telecommunication Union (ITU-T). High-speed Internet users often use dynamic IP addresses, so the IP address changes every time they connect to the Internet.

Therefore, in order to provide a video call interworking service, a high-speed Internet user must first register his or her own IP address in the address translation apparatus 134, where the IP address is either a dynamic IP address or a static IP address. .

The video link subscriber information register 136 registers its Internet ID (ID) and E.164 number among unspecified high speed Internet users to subscribe to the video link service. To help. Here, the address translation apparatus 134 and the video-linked subscriber information register 136 of the present invention are functional classifications and may be included in one device in actual implementation.

FIG. 2 is a video call addressing method (FIG. 2A) and H.323 terminal 152 from 3G.324M terminals 112 and 114 to H.323 terminals 152 and 154 in the network shown in FIG. 154, a video call addressing method (3 (b)) from the 3G.324M terminals 112 and 114 to FIG.

2 (a) illustrates a video call addressing method from 3G.324M terminals 112 and 114 to H.323 terminals 152 and 154. Referring to FIG. 2A, a WCDMA subscriber dials a 3G.324M terminal 112 and 114 by attaching a predetermined prefix to the E.164 number of the H.323 terminals 152 and 154. Then, the mobile network switch 122 receives the prefix and the E.164 number and transmits the E.164 number of the H.323 terminal to the video interlocking device 132 excluding the prefix. For example, the predetermined prefix is "900", the Internet ID of the H.323 terminals 152, 154 (that is, the broadband Internet subscriber) is "kjbaek", the E.164 number is "02-3488-1388", and the IP Assume the address is "250.240.130.9". In this case, the WCDMA subscriber adds the prefix 900 in front of the E.164 number (02-3488-1388) of the H.323 terminals 152 and 154 in the 3G.324M terminal 112 and 114, and the " 900-2- " Dial in the order of 3488-1388 ". Here, "-" is inserted for convenience in order to distinguish numbers and is not used in actual dialing. The mobile switching center 122 then addresses "2-3488-1388" to the video interlocking device 132 except for "900". The E.164 number of "2-3488-1388" is converted into an IP address of "250.240.130.9" by the address translator 134, and the corresponding H.323 terminal (152,) using the IP address (250.240.130.9). 154).

2B illustrates a video communication call addressing method from H.323 terminals 152 and 154 to 3G.324M terminals 112 and 114. Referring to (b) of FIG. 2, a high speed Internet subscriber (ie, an H.323 terminal) directly dials (enters) an MSISDN (Mobile Station ISDN) number of a WCDMA subscriber. Then, the address translation device 134 transmits the incoming MSISDN number to the video interlocking device 132. As an example, assume that the MSISDN number of the WCDMA subscriber is "010-2910-0100". The broadband Internet subscriber dials "010-2910-0100" at the H.323 terminals 152 and 154. The address translator 134 recognizes the WCDMA service identification number "010", determines that the called number is a subscriber of the WCDMA network, and addresses it to the mobile switching center 122 through the video interlocking device 132. The mobile network switch 122 addresses the corresponding 3G.324M terminals 112 and 114 using " 010-2910-0100. &Quot;

3 is a flowchart illustrating a subscriber information registration and IP address registration method of a high speed Internet subscriber according to an embodiment of the present invention.

In order to receive the video call interworking service of the present invention, the broadband subscriber must first subscribe to the video call interlocking service of the present invention and register subscriber information.

Referring to FIG. 3, the high-speed Internet subscriber transmits a video call interworking service subscription request message to the video interlocking subscriber information register 136 to subscribe to the video call interworking service (300). At this time, the video link subscriber information register 136 registers the subscriber's Internet ID and the E.164 number to be used for the video call interworking service. The subscriber's Internet ID and E.164 number may be included in the video call interworking service subscription request message and transmitted to the video linked subscriber information register 136. In addition, the subscriber's Internet ID is included in the video call interworking service subscription request message and transmitted to the video linked subscriber information register 136, and an E.164 number may be automatically assigned. When the subscription request is processed, the video-linked subscriber information register 136 transmits a subscription completion notification message to the video call interworking service subscriber (H.323 terminal) (310). The video link subscriber information register 136 may further include a subscriber's address and contact information.

Subsequently, the video link subscriber information register 136 transmits a subscriber information registration request message to the address translation apparatus 134 (320). Subscriber information registered in the address translation device 134 preferably includes the subscriber's Internet ID and E.164 number. The subscriber's Internet ID and E.164 number must be registered in the address translator 134 so that the IP address of the H.323 terminals 152 and 154 can be registered later and the E.164 number and IP address can be correctly converted. Because. The address conversion apparatus 134 registers the subscriber information and then transmits a registration completion notification message to the video-linked subscriber information register 136 (330).

Process 300 to 330 described above is a procedure that must be performed in order to subscribe to a video call interworking service as a subscriber information registration step (S10). In addition, when the subscriber wants to change the subscription information (for example, the E.164 number) of the high-speed Internet subscriber, the subscriber may send a request for information correction to the video subscriber information register 136 according to the same procedure. Accordingly, the video link subscriber information register 136 automatically updates the modified subscription information (for example, the E.164 number, etc.) in the address conversion apparatus 134.

In the case of ADSL or VDSL-based high-speed Internet, most subscribers use dynamic IP address, so the IP address changes every time they connect to the Internet. Therefore, in order to receive the video call interworking service, the subscriber must be connected to the Internet before attempting the video call, and the subscriber's IP address (that is, the IP address of the H.323 terminal) must be registered in the address conversion apparatus 134. . At this time, the IP address can be used regardless of whether it is a dynamic IP address or a static IP address.

Processes 400 and 410 of FIG. 3 are IP address registration steps 420 of the H.323 terminals 152 and 154. The H.323 terminals 152 and 154 send an H.323 registration request message including their Internet ID, E.164 number, IP address, etc. to the address translation apparatus 134 (400). The address conversion apparatus 134 processes the H.323 registration by determining whether the content of the H.323 registration request message is the same as the message content of step 320 and, as a result, the H.323 registration confirmation message. And transmits to 152 and 154 (410). That is, the address translation device 134 is the subscriber ID and E.164 number transmitted at the IP address registration request 400 of the H.323 terminal 152, 154 has already registered in the subscriber information registration step 320 Check if the ID and E.164 number of the subscriber are the same, and register the IP addresses of the H.323 terminals 152 and 154 only if they are the same. The IP address of the H.323 terminals 152 and 154 must be registered in the address translation apparatus 134 before the call attempt, so that the video call interworking service can be provided.

4 is a flowchart illustrating an embodiment of a video call setup method when a WCDMA subscriber (3G.324M terminal) sends a video call to a high-speed Internet subscriber (H.323 terminal).

Here, it is assumed that the subscriber information registration and the IP address registration of the H.323 terminals 152 and 154 described above with reference to FIG. 3 are already completed.

Referring to FIG. 4, a video call setup request message is transmitted from the 3G.324M terminals 112 and 114 to the mobile network switch 122 (500). At this time, the numbers dialed by the 3G.324M terminals 112 and 114 are given a prefix (e.g., "900") and an E.164 number (e.g., "02-3488") of a high-speed Internet subscriber (called party). -1388 "). Eventually, the WCDMA subscriber dials in the order "900-2-3488-1388".

When the mobile network switch 122 receives the video call setup request from the 3G.324M terminals 112 and 114, the mobile network switch 122 sets the video call including the incoming E.164 number (“2-3488-1388”) except the prefix (“900”). The request message is transmitted to the video interlocking device 132 (510). The video interlocking device 132 transmits a video interworking call setup request message to the address conversion device 134 (520). At this time, the incoming E.164 number ("2-3488-1388") is included in the video interlocking call setup request message. The address conversion device 134 converts the incoming E.164 number (“2-3488-1388”) into an IP address corresponding to the corresponding E.164 number (eg, “250.240.130.9”) to correspond to the corresponding H.323 terminals 152 and 154. In step 530, the H.323 video call setup request message is transmitted. That is, the address translation apparatus 134 sets the video call to the H.323 terminals 152 and 154 using the IP addresses already registered by the H.323 terminals 152 and 154. The H.323 terminals 152 and 154 transmit a video call setup response message to the address translation apparatus 134 (540). The address translation apparatus 134 transmits a video interworking call setup response message to the video interlocking device 132 in response to the video call setup response message from the H.323 terminals 152 and 154 (550). Subsequently, the video interlocking device 132 transmits a video call setup response message to the mobile switching center 122 (560). Subsequently, the mobile switching center sends a 3G.324M call setup response message to the 3G terminal (570). Accordingly, a video call channel is connected between the 3G.324M terminals 112 and 114 and the H.323 terminals 152 and 154 (580).

After the video call channel is connected, if necessary, the video interlocking device 132 performs codec conversion for audio signals and / or video signals between the 3G.324M terminals 112 and 114 and the H.323 terminals 152 and 154. .

5 is a flowchart illustrating an embodiment of a video call setup method when a high-speed Internet subscriber (H.323 terminal) sends a video call to a WCDMA subscriber (3G.324M terminal).

Here, it is also assumed that the subscriber information registration and the IP address registration of the H.323 terminals 152 and 154 described above with reference to FIG. 3 are already completed.

Referring to FIG. 5, the video call setup request message is transmitted from the H.323 terminals 152 and 154 to the address translation apparatus 134 (600). At this time, the H.323 terminal 152, 154 is a called number, the MSISDN (Mobile Station ISDN) number (for example, "010-2910-0100") registered as a video telephone subscriber of the WCDMA network 120 use. That is, the H.323 terminals 152 and 154 attempt a video call by inputting a mobile station ISDN ("010-2910-0100") of the 3G.324M terminals 112 and 114. Here, "010" is a WCDMA service identification number (ie, IMT2000 service identification number).

The address translation apparatus 134 recognizes the WCDMA service identification number "010" in the called number and transmits a video interworking call setup request message to the corresponding video interlocking apparatus 132 (610). When the video interworking call setup request is made, the incoming MSISDN number ("010-2910-0100") is also included and transmitted. The video interlocking device 132 sends a video call setup request message to the mobile network switch 122 corresponding to the incoming MSISDN number ("010-2910-0100") in response to the video interworking call setup request from the address translator 134. Transmit (620). Subsequently, the mobile network switch 122 transmits a video call setup request message to the 3G.324M terminals 112 and 114 corresponding to the called MSISDN number (" 010-2910-0100 ") (630).

If the WCDMA subscriber responds to the video call setup request of the mobile switching center 122 (for example, presses a call button), the 3G.324M terminal 112, 114 sends a video call setup response message to the mobile switching center 122. (640). In response to the video call setup response messages of the 3G.324M terminals 112 and 114, the mobile network switch 122 transmits the video call setup response message to the video interlocking device 132 (650). Subsequently, the video interlocking device 132 transmits the video call interworking call setup response message to the address conversion device 134 (660). The address translation apparatus 134 transmits the H.323 video call setup response message to the H.323 terminals 152 and 154 (670). Accordingly, a call channel is connected between the H.323 terminals 152 and 154 and the 3G.324M terminals 112 and 114 (680).

After the video call channel is connected, the video interlocking device performs codec conversion for audio signals and / or video signals between the 3G.324M terminals 112 and 114 and the H.323 terminals 152 and 154, if necessary.

In this embodiment, the video call interworking between the WCDMA network 120 and the high-speed Internet network has been described. However, the present invention can be applied to interworking between a CDMA network having a same protocol as that of a high-speed Internet network, that is, an H.323 protocol or a wireless Internet network and a WCDMA network. Therefore, the video call interworking system and method of the present invention can be applied to any network to which the H.323 protocol is applied. Examples of networks to which the H.323 protocol can be applied include commercial wireless Internet networks such as "Netspot" and wireless-LAN networks.
