A method for controlling a home network system including a plurality of devices in a home and an access point communicating with the plurality of devices based on an application in a user terminal, the method comprising:
receiving a plurality of reception sensitivities corresponding to each of the plurality of devices and indicating a sensitivity for receiving a signal from the access point;
determining at least one communication failure device placed in a communication failure condition among the plurality of devices by comparing the plurality of reception sensitivities; and
and inducing removal of an obstacle between the at least one communication obstacle device and the access point or displaying a message requesting resetting of physical characteristics of the access point on the user terminal. According to claim 1,
The step of determining the at least one communication failure device,
obtaining a plurality of relative receive sensitivities for the plurality of devices based on the plurality of receive sensitivities;
comparing the plurality of relative receive sensitivities to a threshold receive sensitivities; and
and determining that a device having a relative reception sensitivity lower than the threshold reception sensitivity among the plurality of devices is in a communication failure situation. 3. The method of claim 2,
Obtaining the plurality of relative receive sensitivities comprises:
searching for a maximum reception sensitivity corresponding to a largest value among the plurality of reception sensitivities; and
and obtaining the plurality of relative reception sensitivities by performing an operation of dividing each of the plurality of reception sensitivities by the maximum reception sensitivity. 3. The method of claim 2,
Obtaining the plurality of relative receive sensitivities comprises:
obtaining an average reception sensitivity by averaging the plurality of reception sensitivities; and
and obtaining the plurality of relative reception sensitivities by performing an operation of dividing each of the plurality of reception sensitivities by the average reception sensitivities. According to claim 1,
The step of displaying the message on the user terminal comprises:
Generates an obstacle removal inducing message for inducing removal of an obstacle between at least one device that is not placed in a communication obstacle state among the plurality of devices and an area in which the access point is placed in a home and the at least one communication obstacle device to do; and
Control method comprising the step of displaying the obstacle removal guidance message on the user terminal. According to claim 1,
The step of displaying the message on the user terminal comprises:
Antenna direction change requesting to change the direction of the antenna of the access point from an area in which at least one device that is not placed in a communication failure condition among the plurality of devices is placed in an area in which the at least one communication failure device is placed generating a request message; and
and displaying the antenna direction change request message on the user terminal. According to claim 1,
The control method is
receiving a registration request of a new device to the home network system from outside the user terminal; and
In response to the new device being connected to the access point, the method further comprising: requesting a server for reception sensitivities for the plurality of devices and the new device;
Receiving the plurality of reception sensitivities comprises:
and receiving, by the server, the plurality of reception sensitivities of the plurality of devices and the reception sensitivities of the new device, in response to a reception sensitivity request. According to claim 1,
inquiring through the user terminal whether to enter a reception sensitivity tracking mode for the at least one communication failure device;
receiving a response signal indicating whether the reception sensitivity tracking mode has been entered;
receiving the reception sensitivity of the at least one communication failure device at predetermined time intervals in response to receiving the response signal indicating the entry into the reception sensitivity tracking mode; and
The control method further comprising the step of displaying, through the user terminal, a change in the reception sensitivity of the at least one communication failure device over time. A program stored in a computer-readable recording medium for performing each step according to the method according to any one of claims 1 to 8. A home network system comprising:
an access point that communicates with the server through a first network;
a plurality of devices communicating with the access point through a second network;
a server corresponding to each of the plurality of devices, the server configured to request a plurality of reception sensitivities from the access point, the plurality of reception sensitivities indicating a sensitivity for receiving a signal from the access point; and
Comprising a user terminal for controlling the home network system based on the application,
The access point is
In response to the request from the server, transmit test data to the plurality of devices,
The user terminal is
In response to the plurality of devices receiving the test data, the plurality of devices receive the plurality of receive sensitivities from the plurality of devices, the access point, or the server, and compare the plurality of receive sensitivities to the plurality of devices. Determining at least one communication failure device placed in a communication failure situation, inducing removal of an obstacle between the at least one communication failure device and the access point, or displaying a message requesting resetting of physical characteristics of the access point A home network system, characterized in that.
