How to include. The method of claim 17,
The generating step,
And generating the broadcasting information further including wireless signal strength. The method of claim 17,
Since the step of measuring,
The apparatus further comprising the step of uploading the fine dust information to the central server for the integrated collection of fine dust information distributed by region. A method for a central server device to collect fine dust information measured by network equipment and provide it to a mobile terminal,
Collecting atmospheric fine dust information measured by network equipment;
The collected fine dust information is divided into cell coverage units of the mobile terminal corresponding to the location of the network equipment and stored, and in the case of cell coverage in which fine dust information is not collected, the average fine dust information of adjacent cell coverage is calculated and stored. Managing the fine dust information; And
Receiving a connection request of a mobile terminal, searching for the stored fine dust information corresponding to the cell coverage of the received connection request, and providing it to the mobile terminal
How to include. The method of claim 20,
The collecting step,
And collecting the fine dust information measured by a fine dust measuring device installed in the network equipment including a base station, a telephone pole, and a public telephone booth. The method of claim 20,
After the collecting step,
When the fine dust information is collected from two or more network devices in the cell coverage, the fine dust information is calculated as the average calculated information of the fine dust information of the network devices,
When the fine dust information is collected from one network device in the cell coverage, if the previous measurement time and the current measurement time are less than the reference time, each measurement value is averaged, and if the previous measurement time and the current measurement time exceed the reference time And updating and calculating a current measurement value with fine dust information of the cell coverage. The method of claim 20,
After the collecting step,
And collecting the indoor fine dust information from a mobile terminal receiving indoor fine dust information through IoT communication. The method of claim 23,
Querying the atmospheric fine dust information corresponding to the cell coverage of the mobile terminal in which the indoor fine dust information is collected, and calculating a difference value between the indoor fine dust information and the retrieved atmospheric fine dust information; And
Calculating the indoor ventilation cycle and ventilation time according to the difference value, and transmitting the calculated ventilation information
Method further comprising a. In the method of receiving the fine dust information in the process of receiving a mobile terminal mobile communication service,
Receiving broadcast information including atmospheric fine dust information measured by the device after being connected to a device that transmits a signal of the mobile communication service; And
Outputting the received atmospheric fine dust information to a screen
How to include. The method of claim 25,
The receiving step,
And receiving the broadcasting information further including wireless signal strength. The method of claim 26,
The step of outputting,
When the antenna image according to the received wireless signal strength is displayed on the screen, a method of distinguishing the color of the antenna according to the size of the atmospheric fine dust information and outputting it to the screen. The method of claim 26,
The step of outputting,
And outputting the image of the atmospheric fine dust information to a screen at a position adjacent to a screen output position of the antenna image according to the received wireless signal strength. The method of claim 25,
In the receiving step, when the atmospheric fine dust information is not received,
And accessing a central server to receive atmospheric fine dust information measured by adjacent devices of the device. The method of claim 25,
After the step of outputting,
And receiving indoor fine dust information measured by a nearby Internet of Thing (IoT) terminal and transmitting it to a central server. The method of claim 30,
The step of outputting,
When the antenna image according to the Wi-Fi signal strength is displayed on the screen, a method of distinguishing the color of the antenna according to the size of the indoor fine dust information and outputting it to the screen. The method of claim 30,
And receiving ventilation notification information determined according to a difference value between indoor fine dust information and atmospheric fine dust information calculated by the central server for screen output.
