The service quality assurance system 220 may be performed, for example, by a home gateway that provides an IoT platform / service. The service quality assurance system 220 may control device management and communication to provide a mashup service to a specific area in an environment where a plurality of IoT devices are connected to the Internet 210. [

A plurality of IoT devices may be connected to the Internet 210 through a wired or wireless network. The IoT device 230 may include a sensor or an actuator. The IoT device 230 may include, for example, a lamp installed in each room, a living room, and the like, a standby power cutoff switch, a refrigerator, a boiler shutoff switch, and the like,

The service quality assurance system 220 can monitor whether the service processing time and the response time of the IoT device 230 are delayed according to the load of the central processing unit or the network. At this time, the quality of service guarantee system 220 can measure the percentage of the central processing unit usage, the percentage of the memory usage, the usage percentage of the message / request / event queue of the system, and the increase rate of the usage of the message / have. The service quality assurance system 220 may periodically set a load level.

The service quality assurance system 220 can set a blocking level for blocking the request or message of the IoT device 230 according to the increased load level as the load level is increased beyond a certain reference level. At this time, if the request or message transmitted from the IoT device 230 is lower than the set blocking level as the load level increases by a predetermined reference or more, the request or message transmitted from the IoT device 230 may be blocked.

The service quality assurance system 220 can set a blocking level for blocking the request or message of the IoT device 230 according to the reduced load level as the load level decreases below a certain reference level. At this time, the request or message transmitted from the IoT device 230 can receive the request or message transmitted from the IoT device 230 when the load level is higher than the set blocking level as the load level decreases below a certain standard. For example, the IoT device 230 may receive a request or a message if the cutoff level is lowered or released below a certain criterion.

For example, the service class category of the IoT device that sets the priority can be set in units of devices. If there are various kinds of sensors and actuators in one device, the service class settings of the IoT devices may be different have. Suppose an AooT device, a B IoT device, and a C IoT device.

The service quality assurance system 220 may block the request or message sent from the IoT device 230 if the request or message sent from the IoT device 230 is lower than the set blocking level as the load level increases above a certain reference level have. The service quality assurance system 220 receives the request or message transmitted from the IoT device 230 when the request or message transmitted from the IoT device 230 is higher than the set blocking level as the load level is reduced to a certain level or less can do. For example, suppose you have an IoT device, a B IoT device, and a C IoT device. The service quality assurance system 220 can control the A-IoT device, the B-IOT device, and the CIoT device so that a message related to crime prevention / disaster prevention or a message related to a high priority crime prevention / disaster prevention can be performed first.

The blocking unit 330 may block the request or message transmitted from the IoT device when the request or message transmitted from the IoT device is lower than the blocking level. The blocking unit 330 may block a request or a message transmitted from the IoT device when a request or a message transmitted from the IoT device is lower than a blocking level set as the load level increases beyond a certain reference level. The blocking unit 330 may receive the request or message transmitted from the IoT device when the request or message transmitted from the IoT device is higher than the blocking level set as the load level decreases below a certain level.

The blocking unit 330 can identify the profile of the IoT device that has transmitted the request or the message, classify the profile of the IoT device according to the predefined profile-based priority, and classify it according to the pre- It is possible to determine whether to block the IoT device. At this time, the information about the IoT device can be automatically generated by the IoT device or a profile can be generated through input and search of the user.

4 is a flowchart illustrating a method of ensuring quality of service according to service class category information of an IoT device in an IoT environment according to an exemplary embodiment.

The service quality assurance system can classify the IoT devices to be preferentially processed according to the service class category of the IoT device. The service class category that sets priorities can be set in units of devices, and when there are a plurality of sensors and actuators in a single device, the service classes can be set differently.

In step 410, the service quality assurance system may monitor whether the service processing time and the response time of the IoT device are delayed according to the load of the central processing unit or the network. For example, a service quality assurance system can measure the percentage of central processing unit usage, the percentage of memory usage, the percentage of usage of the system's message / request / event queue, and the rate of increase in usage of the system's message / request / event queue .

In step 420, the service quality assurance system may periodically set a load level. The load level is based on an entry having a maximum value among the percentage of the central processing unit usage, the percentage of the memory usage, the percentage of the system's message / request / event queue usage, Can be set.

In step 450, the quality of service assurance system may set the cutoff level as the load level decreases below a certain criterion.

In step 460, the service quality assurance system may receive the request or message sent from the IoT device if the request or message sent from the IoT device is higher than the set blocking level as the load level drops below a certain criterion.

5 is a flowchart illustrating a method of ensuring quality of service according to the type of IoT device in the IoT environment according to an exemplary embodiment.

The service quality assurance system can classify the IoT devices to be prioritized according to the types of IoT devices. The information of the IoT device can be automatically generated from the IoT device. If the IoT device does not support automatic registration, the profile can be manually generated through user input and search. For example, if the IoT device includes a motion sensor, a proximity sensor, and an illuminance sensor, the user can directly register a sensor included in the IoT device.

In step 510, the service quality assurance system may monitor whether the service processing time and the response time of the IoT device are delayed according to the load of the central processing unit or the network. For example, a service quality assurance system can measure the percentage of central processing unit usage, the percentage of memory usage, the percentage of usage of the system's message / request / event queue, and the rate of increase in usage of the system's message / request / event queue .

For example, the IoT device may include an actuator for comfortably maintaining an indoor environment such as heating, cooling, humidification, etc., and may generate a profile for an actuator and a sensor included in the IoT device.

In step 550, the service quality assurance system may classify the profile of the IoT device according to a predefined profile priority, and determine whether to block the IoT device according to the classified profile. For example, if requests and messages related to cooling maintenance and cooling maintenance during heating and cooling have a higher priority than requests and messages related to heating maintenance, an IoT device that includes a heating function than an IoT device that includes a cooling function There is a high probability of being blocked.

In step 560, the service quality assurance system may block a request or a message transmitted from the IoT device when the request or message transmitted from the IoT device is lower than the set blocking level as the load level increases beyond a certain reference level.

In step 570, the quality of service assurance system may set the cutoff level as the load level decreases below a certain criterion.

In step 580, the quality of service assurance system may receive the request or message sent from the IoT device if the request or message sent from the IoT device is higher than the set blocking level as the load level drops below a certain criterion. For example, a low level message or device message can be received if the level of interception is low or released.
