According to the present invention, when the subscriber sets the video telephone 10 in the outing mode and the outsider invades the home, the fact that the outsider is invaded through the mobile communication terminal 80 and the telephone number of the video telephone 10 is attached. You will receive a short message (SMS). Accordingly, the subscriber makes a call to the video phone 10 through the mobile communication terminal 80 and then inputs a password to receive a video or picture obtained from the video phone 10 from the MMS center 70. Here, the video phone 10 transmits the video or photo obtained through the camera to the media server 60 after the successful password authentication, the media server 60 transmits the video or photo to the MMS center 70, The MMS center 70 transmits a video or picture to the mobile communication terminal 80 in the form of a callback message or a mail according to the type and specification of the mobile communication terminal 80. The above example is a service that allows subscribers to monitor the intrusion of outsiders when they go out.

On the other hand, if the subscriber wants to monitor the situation of the home at the time of going out, for example, to observe the behavior of the young child in the home, the subscriber calls the video telephone 10 preset in the outgoing mode through the mobile communication terminal 80 After dialing the password, a video or photo obtained from the video telephone 10 is received from the MMS center 70. Even in this case, the video phone 10 transmits the video or photo obtained through the camera to the media server 60 after the successful password authentication, and the media server 60 transmits the video or photo to the MMS center 70. In addition, the MMS center 70 transmits a video or photo to the mobile communication terminal 80 in the form of a callback message or a mail according to the model and specification of the mobile communication terminal 80. In such a service, it is desirable for the subscriber to go out after setting the video phone 10 to the outing mode and focusing the camera on a place where a young child frequently visits or a sleeping young child.

Hereinafter, each component of the present invention for implementing a service as described above will be described in detail.

The video telephone 10 is connected to a camera 11 for acquiring a video or a picture, a video encoder 12 for encoding a video or a picture obtained from the camera 11 according to a transmission standard, and a home gateway 30. The mode setting unit 14 in which the communication module 13 in charge of Internet communication, the outing mode, the basic mode, the sleep mode, etc. are set (the mode setting unit 14 may be implemented with a function such as a hot key).

In addition, the speaker 15 and the microphone 16 are provided. Is a basic component of the video telephone 10, but is not necessarily provided in view of the service characteristics of the present invention.

The video phone 10 is provided with a well-known SIP-based video call service, in particular, the video phone 10 is an Internet telephone service to make and receive calls from a terminal belonging to a heterogeneous network, such as a conventional public telephone network, mobile communication network Have a phone number assigned by the operator.

The telephone number of the video telephone 10 as described above is registered in the home management server 40 and the SIP system 50, and the IP address of the video telephone 10 (particularly the IP address of the home gateway 30) and the SIP URL and Phone numbers assigned by Internet phone service providers are mapped and registered.

Here, the SIP system 50 manages the voice gateway 51 for establishing call calls between terminals belonging to heterogeneous networks, and location information (or routing information, for example, IP address, SIP URL, and telephone number) of each subscriber. It will be made by the location server 52, it will be readily understood by those skilled in the art that the basic system such as a known SIP exchanger is provided in the SIP system 50.

As another example, the video phone 10 may be provided with a known H.323-based video call service. That is, the SIP system 50 may be replaced with an H.323 system composed of a gateway, an MC, a gatekeeper, and the like. The H.323 system is a video telephone from a specific mobile communication terminal. When a voice call connection request is received, a call is established between the specific mobile communication terminal and the video telephone. For reference, H.323 is a VOIP protocol established by the International Telecommunication Union (ITU), and SIP is a VOIP protocol established by the Internet Engineering Task Force (IETF) -MMUSIC WG. Hereinafter, a SIP system will be described as an example, and it will be easily understood by those skilled in the art that the H.323 system may be applied to the present invention.

On the other hand, the home gateway 30 has an Internet connection function of each home automation device (image telephone 10, security device 20, etc.) installed in the home, an addition / update / registration / deletion function of each home automation device, It is in charge of the function of managing / controlling each home automation device by the control communication of the home management server 40. FIG.

In addition, the home gateway 30 is assigned an IP address from an Internet service provider associated with the home management server 40 and is assigned a fixed IP address or a dynamic IP address, and through its own Plug & Play function. The home management server 40 performs home automation device addition / update / registration / deletion. That is, the home gateway 30 assigns a virtual IP address or a specific port number to the video telephone 10 through the DHCP function, and the home gateway 30 registers information of each home automation device with the home management server 40. At the time of update, the information of the video telephone 10 is registered.

In addition, the home gateway 30 may be connected to each of the video telephone 10 and the security device 20 by wire or wirelessly. Preferably, the home gateway 30 performs a wireless communication function with ZigBee. Here, Zigbee is a standard technology for home automation and data networks having a low transmission rate, which is a dual physical layer type, and uses a frequency band of 2.4 GHz and 868/915 MHz, and the modem method is DSSS (Direct Sequence Spread Spectrum). The MAC uses CSMA / CA, and data rates can range from 20kbps to 250kbps.

On the other hand, the case of making a call to the video phone 10 from the mobile communication terminal 80 will be briefly described as follows.

When the mobile communication terminal 80 requests a voice call call connection to the telephone number of the video telephone 10, the mobile communication switch (not shown) recognizes that the telephone number is a SIP-based call service telephone number. The voice call call connection request of the terminal 80 is forwarded to a SIP system, preferably a SIP switch. Then, the SIP switch converts the voice call of the mobile communication terminal 80 into a video call and requests the video call connection to the video phone 10. Accordingly, in the video telephone 10, the telephone rings and the call is established by the subscriber's picking up the receiver. On the other hand, in the present invention, when the outgoing mode is set in the video telephone 10, the video telephone 10 will send a password input guide message when a call comes in like a conventional missed guidance without the subscriber picking up the handset.

On the other hand, video or photo obtained in real time from the camera 11 in the video phone 10 is encoded according to the specifications and models of the mobile communication terminal 80 of the subscriber or from the video phone 10 in the media server 60 The received video or photo may be converted to suit the specifications and model of the mobile communication terminal 80 of the subscriber. In addition, it is preferable that the video phone 10, especially the control unit 18, control the camera 11 to photograph the indoor situation in real time after the successful password authentication.

The security device 20 is a device that monitors whether an outsider invades the home, and is implemented as a sensor such as a magnetic sensor or a fuselage monitoring sensor. For example, when the magnetic sensor installed at the entrance of the home detects the departure of the magnet mounted on the door, it is determined that an outsider has entered the home. When the security device 20 detects an outsider's intrusion into the home, the security device 20 connects to the home management server 40 through the home gateway 30 and reports the outsider's intrusion. Accordingly, the home management server 40 is attached to the subscriber's mobile communication terminal 80 already registered through the MMS center 70 (or SMS center), and the intrusion of outsiders and the telephone number of the video telephone 10 are attached. Ask for a short message.

The home management server 40 remotely controls each home automation device while communicating with the home gateway 30 installed in each home. The home management server 40 is registered with the information of each premises, in particular, in the present invention, the telephone number of the subscriber's mobile terminal 80 and the telephone number of the video phone 10 is registered, the security device 20 If the intrusion is reported from the subscriber to the mobile communication terminal 80 to send a short message with the external intrusion facts and the phone number of the video phone 10 attached.

When the media server 60 receives the video or picture from the video phone 10, the media server 60 stores the video or picture in the DB 61 as a specific URL to be mapped to the information of the corresponding subscriber. Here, since the media server 60 cannot directly transmit a moving picture or a picture to the mobile communication terminal 80, it is preferable to request a moving picture or picture stored at a specific URL through the MMS center 70.

The MMS center 70 transmits a video or picture to the subscriber's mobile communication terminal 80 when the media server 60 receives a request for transmission of a video or picture stored in a specific URL. Here, when the mobile communication terminal 80 is a terminal that supports the MMS function, the MMS center 70 transmits a moving picture or a picture stored in a specific URL in a mail form by a push method. Meanwhile, when the mobile communication terminal 80 is a terminal (eg, a photo terminal) that does not support the MMS function, the MMS center 70 inserts URL information in which a video or a picture is stored into a callback message to insert the URL into a callback message. Send to 80. Accordingly, the mobile communication terminal 80 performs a response to the callback message and accesses the corresponding URL to play the video or picture.

2 is a flowchart illustrating a home monitoring method using a video telephone according to the present invention.

First, the go out mode is set in the video telephone 10 (200). Here, when the user goes out, the user presses a button of the video telephone 10 to set the outing mode or connects to the home management server 40 through a mobile communication terminal 80 or a computer (not shown). The indoor video telephone 10 can be set to the outing mode remotely. As another example, a user may call the video telephone 10 from the outside and directly set the outing mode.

Subsequently, when an invasion of an outsider is detected in the home security device 20 (201), the security device 20 reports the outsider intrusion to the home management server 40 through the home gateway 30 (202). .

Then, the home management server 40 is a DB (not shown in the figure) of the telephone number of the subscriber mobile communication terminal 80 of the home belonging to the security device 20 and the telephone number of the video phone 10 of the indoor home. Check through (203).

Then, the home management server 40 transmits an external intrusion fact and a short message (preferably a callback message with a phone number inserted) to which the telephone number of the video telephone 10 is attached, to the mobile communication terminal 80. The MMS center (or SMS center) 70 is requested (204).

Then, the MMS center 70 transmits to the mobile communication terminal 80 a callback message in which the external intrusion fact and the telephone number of the video telephone 10 are inserted (205). In this case, the mobile communication terminal 80 receives a callback message, and the subscriber makes a call to the telephone number of the video telephone 10 while recognizing that an outsider is invaded in his or her home.

Accordingly, the mobile communication terminal 80 requests a voice call connection to the video telephone 10 to the SIP system 50 through the mobile communication exchange, the SIP exchange, or the like (206).

Then, the SIP system 50 processes the voice call connection request of the mobile communication terminal 80 appropriately for the SIP and notifies the video telephone 10 that there is a video call connection request from the mobile communication terminal 80 ( 207).

Accordingly, the video phone 10 responds to the video call connection request to the SIP system 50 without lifting a specific person's handset according to the outgoing mode setting (208). Here, the video phone 10, when receiving a video call connection request should ring the phone ring according to a known SIP call processing procedure, but when the outgoing mode is set to answer without ringing the phone so that outsiders do not recognize that a call It is preferable.

Then, in a state where a call is established between the mobile communication terminal 80 and the video telephone 10 by the SIP system 50, the video telephone 10 sends a password input guide message to the mobile terminal subscriber. Ask for input (209).

Accordingly, the mobile terminal subscriber enters the password (210). Then, the video phone 10 recognizes the normal password and authenticates the input password, and recognizes the normal subscriber to drive the camera 11 to capture the situation of the home in real time and encode it into a video or a picture (211). Here, the video phone 10 can encode a moving picture or a picture in accordance with the model and specifications of the mobile communication terminal 80 of the subscriber.

Then, the video phone 211 transmits the encoded video or picture to the media server 60 and requests the subscriber to send it to the mobile communication terminal 80 of the corresponding subscriber (212).

Then, the media server 60 stores the received video or photo as a specific URL (213). Here, the media server 60 may encode and store the video or photo received from the video phone 10 into a video or photo according to the model and specification of the mobile communication terminal 80.

Thereafter, the media server 60 requests the MMS center 70 to transmit a specific URL in which a video or photo of the home is stored to the subscriber's mobile communication terminal 80 as a callback message (214).

Then, the MMS center 70 inserts a specific URL in which a video or photo of the home is stored in the callback message and transmits the specific URL to the subscriber's mobile communication terminal 80 (215).

Accordingly, the mobile communication terminal 80 receives the callback message, and the subscriber recognizes the URL where the home video or the picture is stored and accesses the URL in response to the callback message to watch the home image (216).

As another example, when the MMS center 70 is a terminal (eg, photo terminal, etc.) that does not support the MMS function by determining the type, specification, etc. of the mobile communication terminal 80 of the subscriber to receive the video or picture as described above In the case of a terminal supporting the MMS function, the terminal may be directly transmitted to the mobile communication terminal 80 by attaching a video or photo to a mail by a push method rather than a callback message. The mobile communication terminal 80 may directly receive a video or picture without a URL connection.

On the other hand, in another embodiment of the present invention, that is, when the subscriber wants to monitor the situation of the home when the user goes out, for example, to observe the behavior of the young child in the home, the security device 20 is not necessarily provided, The subscriber may set the mode of the video telephone 10 to the outing mode at the time of going out. In other words, when the subscriber wants to check the home situation remotely while setting the video phone 10 in the outing mode, the subscriber may call the video phone 10 as described above and proceed with the subsequent process. Here, it is preferable that the subscriber knows the telephone number of the video telephone 10 in advance.

Although the above has been described with reference to the preferred embodiment according to the present invention, those skilled in the art to which the present invention pertains can be carried out by other specific forms of example without changing the technical spirit or essential features of the present invention.
