The home network server 200 may have one server representative telephone number 010-2738-0001. As a result, the mother's smartphone displays a message of returning the child from the above phone number 010-2738-0001.

FIG. 4 is a flowchart of an operation at the time of a return home event and a visit event according to FIG. 1;

Referring to FIG. 4, if the MIM service entry is performed in step S400, and if it is a return event in step S410, the corresponding search is performed in step S420. Here, the person in ears can be a child in the above example. After the ears have been searched for in step S430, it is checked whether the registration informant is out, and if it is out, the mobile instant message is transmitted in step S440. Here, the registration notifier can be a mother in the above example.

On the other hand, if the event is not a return event, in step S470, a visitor image is acquired in step S480, and it is checked in step S430 whether the registration notification is going out. If the user is out, the visitor image is transmitted in step S440 or a visitor notification message indicating that there is a visitor is transmitted as a mobile instant message. On the other hand, the judgment when the registration informant is going out can be recognized as being out of the house when it is detected that the household passes the same entrance or has passed through the parking exit using the vehicle. On the other hand, it is to be understood that the step of checking out is inserted, but it is not limited to this and it is to be understood that the checking step during outgoing can be omitted according to the case.

Therefore, a message such as 602 or 604 in the screen of FIG. 6 may be displayed on the registration informant, for example, the mother smartphone.

FIG. 6 is an exemplary view of a bidirectional communication message at a home event according to FIG. 1, and FIG. 7 is an exemplary view illustrating a bidirectional communication message at a visiting event according to FIG. 1;

In FIG. 6, a message 602 is in the form of a typical KakaoTalk text message. In this case, "I came home!" Is automatically displayed on the mother's smartphone only by the child's door opening operation. That is, the child does not send the above message by pressing the character key, but is automatically sent by the message sending server 200.

Meanwhile, a message such as 604 is a preset picture message and represents a return event in the form of an emoticon. Eventually, when the emoticon is displayed on the mother's smartphone automatically by the door opening operation of the child, the mother recognizes that the child has returned home.

In this case, the mother can send a response message, such as reference 610. For example, you can write a response saying "Have you been to my daughter 's school and have a snack in the refrigerator?" Accordingly, the home network server as the message sending server 200 receives the MIM response.

Accordingly, it is checked whether there is an MIM response reception in step S450, and if a response message is received, the reception message is transmitted to the corresponding month pad or door phone in step S460. Therefore, the above-mentioned response message may be displayed on the wall pad.

In FIG. 7, the message 701 is in the form of a typical KakaoTalk text message. In this case, the message "There is a visitor" is automatically displayed on the smartphone of the mom or dad (in case of registration setting) only by the appearance of the visitor. That is, the visitor does not send the above message by typing a character key, but sends it automatically at the event of a visit at the message sending server 200.

Meanwhile, a message such as the reference numeral 703 is a preset picture message and represents a visit event in the form of an emoticon. Eventually, when the emoticon is automatically displayed on the smartphone of the mom or dad by the appearance of the visitor, the visitor is recognized.

Also, in this case, a message such as 705 is displayed and the image of the visitor can be displayed on the smartphone of the mom or dad when the arrow is pressed.

Accordingly, the mother or father can send a response message such as reference numeral 710. For example, if you are a simple visitor or a courier, you can write and send a "Please visit tomorrow afternoon" response message. Accordingly, the home network server as the message sending server 200 receives the MIM response.

Accordingly, it is checked whether the MIM response is received in step S450, and if a response message is received, the received message is transmitted to the door phone in step S460. Thus, through the door phone speaker, the visitor will be able to hear a request to visit tomorrow afternoon.

FIG. 5 is a flowchart of a home facility control and security event at the time of a security event according to FIG.

Referring to FIG. 5, the MIM service entry is performed in step S500, and if the home appliance or the home appliance is in the control mode in step S510, it is checked whether the registration notification is going out in step S520. If the registration informant to be informed of the message is going out, the mobile instant message containing the status information is transmitted in step S530. Here, the registration notification can be a mother or a father.

If it is determined in step S570 that an intrusion has occurred, an image of the secure zone is acquired in step S580, and an image is transmitted in step S530.

On the other hand, the judgment when the registration informant is going out can be recognized as being out of the house when it is detected that the household passes the same entrance or has passed through the parking exit using the vehicle. On the other hand, it is to be understood that the step of checking out is inserted, but it is not limited to this and it is to be understood that the checking step during outgoing can be omitted according to the case.

Therefore, the smartphone of the registration informant can display the state information of the home appliance or the image of the invasion situation similarly to the screen of Fig. 6 or Fig.

If the condition of the home equipment is abnormal, for example when the temperature of the boiler is notified as overheating, the registration informer can send a response message. For example, you can send a message to the response message to bring down the boiler operating temperature. Accordingly, the home network server as the message sending server 200 receives the MIM response.

Accordingly, it is checked whether the MIM response is received in step S540, and if there is a response message, the home facility and the control message of the device are transmitted to the monthly pad of the corresponding lake in step S550. The control message is provided to a boiler or other home facility so that the registration notification can be controlled in a desired direction. On the other hand, the execution of the processing of the security situation can also be implemented when the response message is received. For example, a DVR installed within a household can record an intrusion situation or make an alarm siren ring.

As described above, there is an advantage in that the mobile device can automatically transmit the control of the home facility or the security situation to the home of the child or the home visit, or the mobile device via the home device. In addition, the other party receiving the mobile instant message can transmit the response message as a mobile instant message in reverse, so that two-way free communication can be performed when a free text service such as KakaoTalk is used.

On the other hand, although KakaoTalk has been described as a mobile instant message, the present invention is not limited thereto. For example, a mobile instant message may include a message service using a Social Networking Service (SNS) such as Twitter or Facebook. In addition to KakaoTalk, a mobile instant messenger having a friend auto registration function such as whatsApp, next MyPhone, Naver Line, etc. can be used.
