1 is a diagram showing the configuration of a system for providing a video catch call according to an embodiment of the present invention.

The system 100 for providing a video catch call according to an embodiment of the present invention is located between the mobile communication terminals 110a and 110b, the mobile communication terminals 110a and 110b, and the base station controller to be suitable for a wireless link and a wired link. A base station (Node-B, hereinafter referred to as Node-B) 120 for converting a signal format, and a base station controller (Radio Network Controller, hereinafter referred to as RNC) 130 for managing and controlling the Node-B 120. In response to the video catch call processing request, HLRs 140a and 140b transmitting the video catch call request message including the video call request information, and receiving the video catch call request message, the text transmission request message including the video call request information. Video catch call server (Catch Call System Server, hereinafter referred to as CCS) for transmitting the 150, SMC 160 for receiving a text transmission request message, and transmits a short incoming call request message containing the video call request information, short Incoming request message Receive MSC (170a, 170b) for receiving a video catch call message including the video call request information to the called terminal and history information on the video catch call generation and processing results from the CCS 150, and the history information It includes a customer management server to provide a subscriber.

Hereinafter, the configuration of the system 100 described above will be described in more detail.

First, the mobile communication terminals 110a and 110b generally include a cellular phone, a personal digital assistant (PDA), a personal communication services phone (PCS), and an IMT-2000 terminal (International). A mobile communication terminal according to an embodiment of the present invention includes a device that provides a communication function for making a call or exchanging data while moving, such as a Mobile Telecommunication-2000) and a Global System For Mobile Communication (GSM) terminal. 110a and 110b provide a video call function through a 3G communication network.

Here, 110a denotes an outgoing mobile communication terminal, and 110b denotes an incoming mobile communication terminal.

The Node-B 120 performs a wireless modem function consisting of an antenna and a transmission / reception modem.

For reference, a channel from the mobile communication terminals 110a and 110b to the Node-B 120 is referred to as an uplink channel or a reverse channel, and a channel from the Node-B 120 to the mobile communication terminals 110a and 110b is downlinked. Or Forward channel.

In the present invention, a case where a channel is connected to a Node-B 120 from the mobile communication terminals 110a and 110b, that is, an uplink channel, is used to transmit / receive.

The RNC 130 instructs the Node-B 120 to allocate a radio channel to the mobile communication terminals 110a and 110b with about 10 to 40 Node-Bs 120, and the mobile communication terminals 110a, Control the transmission output of 110b).

And a handover for the mobile communication terminal (110a, 110b) that connects the voice and video communication path between the mobile communication terminals (110a, 110b) connected to the Node-B 120, and moves between the Node-B (120) It is a kind of small exchange that supports it.

In addition, the RNC 130 may include a location area identifier (LAI), which is a unique location area identification number assigned to each RNC 130, so that the mobile communication terminals 110a and 110b know which location area they are. Note that the configuration of the Node-B 120 and the RNC 130 is referred to as one base station subsystem (Radio Access Network, RAN) for periodic broadcasting.

The MSCs 170a and 170b are a kind of telephone exchange having multiple RNCs 130 and providing a connection with an external landline or a mobile communication terminal elsewhere.

Of course, compared to a general telephone, since the mobility of the terminal needs to support a function such as transmitting a paging message for searching the receiving terminal, the MSC (170a, 170b) according to an embodiment of the present invention is a 3G communication network Provide video call function.

For reference, in the configuration of the system of the present invention, 170a is the originating MSC, 170b means the destination MSC, out of the originating MSC and the destination MSC, in the detailed description of the present invention will be described with respect to the destination MSC (170b).

Detailed description of the incoming MSC 170b will be described later.

The HLRs 140a and 140b may include fixed information such as a terminal's telephone number (MSISDN), an international mobile station identification number (IMSI), subscriber information, service type, authentication information, and current dynamic location information (VLR address of the current location, HLR may be installed in the MSC or installed separately.

The HLRs 140a and 140b according to an embodiment of the present invention provide a video call function through a 3G communication network.

For reference, in the configuration of the system of the present invention 140a is the originating HLR, 140b means the incoming HLR, out of the outgoing HLR and the destination HLR, in the detailed description of the present invention will be described centering on the destination HLR (140b).

If the video call connection with the called party is not established, the HLR 140b requests the video catch call processing, and transmits the video catch call request message including the video call request information to the CCS 150.

Here, the video call request information may include a voice / video identifier and may indicate that the corresponding call is a video call by allocating a predetermined bit.

For reference, the video catch call request message including the video call request information according to an embodiment of the present invention uses Information Directive2 (INFO_DIR2) defined in the international standard IS41D.

The CCS 150 receives the aforementioned video catch call request message from the HLR 140b, extracts the video call request information, and then transmits a text transmission request message including the video call request information to the SMC 160.

In this case, the text transmission request message SUBMIT includes a video catch call short message to be displayed on the receiver's mobile communication terminal 110b, and includes the receiver's mobile phone number, the caller's mobile phone number, and the above-mentioned video call request information. .

For reference, the CCS 150 manages subscriber information. The subscriber information managed by the CCS 150 includes a terminal identification number (MSID), subscriber telephone number (MDN), service activation, subscriber registration time, and recent SMS transmission. Include the time and the subscriber's telephone number where the latest SMS transmission occurred.

Here, the 'recent SMS transmission occurrence time' is the time of the last SMS transmission to the subscriber, and the 'recent SMS transmission occurrence subscriber's phone number' is the outgoing information of the last SMS transmission to the subscriber.

The reason why the CCS 150 manages the 'recent SMS transmission occurrence time' and 'recent SMS transmission occurrence subscriber's phone number' is that if multiple incomplete calls from the same sender occur in succession, the first call is not sent every time. This is to minimize the inconvenience of subscribers by notifying SMS only for the completed call.

In addition, the CCS 150 manages the subscriber information and the history information on the image catch call generation and the processing result as described above to the customer management server 180, so that the subscriber accesses a predetermined information providing site in a web environment. Video catch call history can be inquired.

The SMC 160 receives the text transmission request message from the CCS 150, extracts the video call request information, and then transmits a short incoming call request message including the video call request information to the MSC 170b.

In addition, the SMC 160 transmits the destination terminal location request message to the HLR 140b, because the SMC 160 does not know information about the location of the destination terminal, and thus, the destination terminal of the destination terminal through the HLR 140b. To determine the location.

For reference, the short incoming call request message including the video call request information transmitted from the SMC 160 to the MSC 170b according to an embodiment of the present invention uses MT_FORWARD_SM defined in the international standard 3GPP, and the SMC 160. ), The location request message of the called terminal transmitted to the HLR 140b uses SRI_FOR_SM defined in International Standard 3GPP.

Meanwhile, the MSC 170b receives the short call request message from the SMC 160, extracts the video call request information, and transmits a video catch call message including the video call request information to the called mobile communication terminal 110b.

For reference, the video catch call message including the video call request information according to an embodiment of the present invention uses SMS_CP_DATA defined in the international standard 3GPP, and the MSC transmits the text to the mobile terminal in the international standard. Is the standard used when.

The incoming mobile communication terminal 110b receives a video catch call message from the MSC 170b.

Then, when the call button is selected, the incoming mobile communication terminal 110b checks whether the video catch call message includes the video call request information, that is, whether the video separator is included, and attempts to make a video call if the video separator is included.

For reference, names and operation names of messages transmitted and received between configurations of the system referred to in the present invention may have the same effect by using different messages or specified in different standards according to various embodiments of the person skilled in the art. It is not limited to the embodiment of the invention.
