## Background
CROSS REFERENCE TO RELATED APPLICATION

BACKGROUND OF THE DISCLOSURE
Field of the Disclosure
Exemplary embodiments of the disclosure relate to a smart access point apparatus and a method for controlling an IoT (Internet of Things) apparatus using the smart access point apparatus.
Discussion of the Background
Internet of Things (namely, IoT) is a new form evolving from conventional USN (Ubiquitous Sensor Network) or M2M (Machine to Machine). A main object of conventional M2M is the communication of end-devices with humans. A main object of IoT is to enable communication of things such as telephones, books, thermometers with humans. Specifically, the IoT may mean a things-space internet network which cooperatively forms intelligent relations among three diverse environmental factors including people, things and services, without human explicit intervention.
Besides such IoT, various concepts and technologies such as WoT (Web of Things) and WoO (Web of Objects) are under study and development. With development and distribution of such concepts and technologies, it is expected that use of devices (e.g., gadget devices, sensor devices and actuators) giving users easy access to the internet will increase.
As the IoT environment has come, there is a growing need to introduce a service for controlling various IoT devices in a specific spatial environment. For instance, a user has to control setting for temperatures, ventilation, luminance, sound and the like based on a purpose of use, in case of a conference room in a smart building.
FIG. 1 is a diagram illustrating an IoT environment in a prior art. It is shown in FIG. 1 that various IoT devices are provided in a specific spatial environment. At this time, a user 120 can control special services after accessed to special services associated with a smart lightening through a device possessed by the user 120 to control an IoT device such as a smart lightening.
However, in the prior art, each of spatial environments are provided (e.g., a home, an office, a conference room and the like). Considering that various IoT devices are provided in each of the spatial environments, it is quite inconvenient for users to access to each of the special services provided to each of the IoT devices.
Moreover, there are only closed and vertical relations between the user's device and each of the IoT devices but insufficient information about the space of the devices. For instance, the prior art uses only a relation between a first IoT device and the user's device and a relation between a second IoT device and the user's device, failing to recognize whether the first IoT device and the second IoT device are provided in the same space (e.g., one of offices). However, the associated and/or integrated control for an air conditioner and a humidifier is required in one space, for instance.

Hereinafter, exemplary embodiments of the disclosed subject matter will be described in detail with reference to the accompanying drawings.
FIG. 2 is a diagram illustrating an IoT environment according to the exemplary embodiments of the disclosure. It is shown in FIG. 2 that various IoT devices are provided in a specific spatial environment 210. At this time, a user 220 may access a IoT device control master 230 further provided in the specific spatial environment 210, not accessing services provided in each of the IoT devices in the prior art, using a user's device.
The IoT device control master 230 may provide the user 220 with a service for controlling IoT devices provided in a corresponding space through the user's device. For that, the IoT device control master 230 shown in FIG. 2 can communicate with various IoT devices provided in a specific space environment 210.
A computing environment of things requires an access point for accessing a device of things provided in a specific space to access a device of things provided in a specific space to a computing environment of things. The access point has to support access of the various IoT devices. To support the access, a computing environment of things for controlling and virtualizing a device of things (or an IoT device) may be required in environments such as IoT (Internet of things), WoT (Web of Things) and WoO (Web of Objects), besides a network access device. For instance, the computing environment of things may mean an environment for virtualizing and driving each of the IoT devices.
The exemplary embodiments of the disclosure describe a method and a system for directly driving and controlling IoT devices accessed by a smart access point such as the IoT device control master 230 shown in FIG. 2. The access point needs to be converted into a smart access point apparatus as a service execution environment of accessed IoT devices, not simply as a network access passage. VO (Virtual Object) of various things (e.g., the IoT devices shown in FIG. 2) may be implemented on a smart access point and a user (e.g., the user 220 shown in FIG. 2) may control the IoT devices through interworking with a desired virtual object.
Accordingly, the user needs a method of how controlling a desired IoT after accessing a smart access point provided in a specific space.
As mentioned hereinabove, the smart access point may be a device for providing a service of accessing an IoT device at a one-hop distance and driving the IoT devices virtualized as virtual objects. Such the smart access point may include an interface for communicating with various IoT devices, using various interworking protocols such as WLAN (Wireless Local Area Network), Zigbee, Bluetooth, Z-wave, Ethernet, RS232 and the like.
FIG. 3 is a diagram illustrating one embodiment of a hardware configuration provided in a smart access point according to the exemplary embodiments of the disclosure. FIG. 3 shows MPU (Micro MPU(Micro Processor Unit), JTAG(Joint Test Action Group), SD/MMC(Secure Digital/Multi-Media Card), EEPROM(Electrically Erasable and Programmable Read-Only Memory), RS232 Serial, Zigbee/Bluetooth/Z-wave, USB PHY, USB Type A, DDR2/3, Mini PCI(Peripheral Component Interconnect) Express, PHY, RJ45, Clocking, Power Circuit, POR(Power On Reset), Cfg(Configuration) and POE(Power Over Ethernet). Each of elements is well-known in the art to which the disclosure pertains and detailed description thereof is omitted accordingly. FIG. 3 illustrates one embodiment of a hardware configuration provided in the smart access point. The smart access point may further include elements not shown in FIG. 2 or a predetermined number of elements may be omitted. Or, combination of two or more elements may be configurated or arranged.
FIG. 4 is a diagram illustrating one embodiment of a network configuration provided in the smart access point according to the exemplary embodiments of the disclosure. FIG. 4 shows a smart gateway S/W block 410 as the smart access point. The smart access point is arranged in the same position as a conventional wireless access point such that it may have two access properties of a public network 420 and a private network 430. When seen outdoors, the smart access point may be recognized as a subject of information management and access to a specific space (in other words, a space accessible to a smart access point). When seen indoors, it may be recognized as a bridge between accessed devices.
In case of a private network 430 connected with the IoT devices, the smart access point may provide various network interfaces and adaptor functions to access the IoT devices in a one-hop distance such that presence of corresponding IoT device access, an intensity of a signal for the corresponding IoT device can be explicitly recognized. Accordingly, the smart access point may provide a mutual network adaptation function when the IoT devices having different protocols loaded therein are in D2D (Device to Device) or P2P (Peer to Peer) communication with each other. Moreover, the smart access point may detect information about one-hop distances and implement a function of simultaneous interworking control. Each of specific IoT devices need not requires a high intelligence to provide a D2D function and the IoT devices can be controlled less expensively.
The smart gateway software block 410 may include an instance application service 440, an instance manager 450 and a network adaptor 460.
The instance application server 440 may be operated as WAS (Web Application Server) and provide web accessible devices of the public network 420 with services associated with the IoT devices, using a web interface.
The instance manager 450 may be a main module associated with generation and driving of instances and manage/schedule a life cycle of an instance. The instance manager 450 may include an instance engine 451 for providing an instance operation environment, an instance pool 452 for pooling the instance and a message router 453 for routing an input/output message associated with the IoT devices.
The network adaptor 460 may provide a function of a physical access to the IoT devices through a wire or wirelessly based on network interface specifications supported by the smart access point. For instance, the network adaptor 460 may provide an adaptor function for network interworking, using various communication protocols. Examples of the various communication protocols may include WLAN(Wireless Local Area Network), Zigbee, Bluetooth, Z-wave, Ethernet, RS232 serial and the like. The network adaptor 460 may further provide a message parsing function for processing a message based on each of the network interface specifications. In the IoT environment, the IoT devices use various message formats based on characteristics thereof. Accordingly, when using NF network interface technologies, the network adaptor 460 may further provide a function of structuralizing message data sent from the IoT devices based on a format for each instance according to the characteristic of the specific network interface.
FIG. 5 is a diagram illustrating one embodiment of an IoT list screen according to the exemplary embodiments of the disclosure. FIG. 6 is a diagram illustrating one embodiment of an IoT application implementation screen according to the exemplary embodiments of the disclosure. To access the smart access point to the IoT devices, a virtual object of the specific IoT device has to be deployed on an instance manager of the smart access point. The deployed virtual object may represent the specific IoT device. The virtual object may be divided into a device linkage type and a mesh up type. The device linkage type virtual object may mean a virtual object directly linked to one or more IoT devices. The mesh up type virtual object may mean a virtual object linked with one or more device linkage type virtual object. The virtual object provided on the instance manager may be an instance and instances may be managed on the instance manager. The user may use a service through a web or a private web to use and control various instances driven on the smart access point. At this time, the virtual objects shown in FIGS. 5 and 6 may be registered as icon types. In this instance, each of the IoT devices may be provided as an application icon. FIG. 5 shows one embodiment of a screen providing the user with a list of application (App.) icons. FIG. 6 shows one embodiment of a screen implementing an application associated with a humidifier by the user's selection of an icon associated with a humidifier.
FIG. 7 is a diagram illustrating one embodiment of a method for providing a service according to exemplary embodiments of the disclosure. FIG. 7 shows a method of providing a service to a user terminal 710 and a smart access point 720. At this time, a service providing method may be divided into two methods.
In one of the two methods, the user terminal may access the smart access point 720 and receives a list of virtual objects for useable IoT devices, so as to control the IoT devices individually. As shown in a first dotted box 730 shown in FIG. 7, the method may include a first step for the user terminal 710 requesting the smart access point 720 for information about a service, a second step for the smart access point 720 sending the service list to the user terminal 710 and a third step for the user terminal 710 using a corresponding service through the smart access point 720.
In the other method, the smart access point 720 requests the user terminal linked wirelessly for a service profile and provides services actively. As shown in a second dotted box 740 shown in FIG. 7, the method may include a first step for the smart access point 720 requesting the user terminal 710 for the user profile, a second step for the user terminal 710 responding to the user profile requested by the smart access point 720, a third step for the smart access point 720 providing services actively based on the user profile, a fourth step for the user terminal 710 transmitting a user intent to the smart access point 720 and a fifth step for the smart access point 720 providing services actively based more on the user intent.
FIG. 8 is a diagram illustrating one embodiment of a method for providing a service, using a service list, according to exemplary embodiments of the disclosure. FIG. 8 shows a user 810, a manger 820, a smart access point 830 (Smart AP) and an IoT device 840 (IoT Device). The user 810 and the manager 820 may be the same subject or different objects. Substantially, the user 810 and the manager 820 may be devices used to access the smart access point 830. A plurality of IoT devices 840 may be provided.
A device possessed by the user 810 accesses the smart access point 830 and checks presence of a service provided by the smart access point 830. In case that the smart access point 830 provides a service associated with the IoT devices 840, the user's device may be notice whether the service is usable. For instance, the access between the user's device and the smart access point 830 may be web-based.
In a step 851, the manager 820 may deploy a virtual object (VO) of an IoT device 840 accessible to the smart access point 830 in the smart access point 830. For instance, the manager 820 may approach the smart access point 830 and implement the deployment of the virtual object. The smart access point 830 may deploy the virtual object in a step 851-1.
In a step 852, the smart access point 830 may implement interworking with the IoT device 840. At this time, the IoT device 840 may interwork with a corresponding virtual object deployed in the smart access point 830.
In a step 853, the smart access point 830 may broadcast information on instance running of the virtual object and presence of a space IoT control function. For instance, the smart access point 830 may broadcast a message (or a space IoT controllable message which will be described later) containing information on providing of the functions mentioned above to linked terminals.
In a step 854, the user 810 may approach the smart access point 830 wirelessly. In a step 855, a wireless network may be connected between the user 810 and the smart access point 830.
In a step 856, the user 810 may receive a space IoT controllable message. Here, the space IoT controllable message may be corresponding to the message broadcasted by the smart access point 830 in the step 853.
In a step 857, the user 810 may request the smart access point 830 for a list of services useable on the smart access point 830.
In a step 858, the smart access point 830 may grasp the user's permissions and create a list of virtual objects which can be provided among operating virtual objects.
In a step 859, the smart access point 830 may transmit the list of the services useable on the smart access point 830.
In a step 860, the user 810 may request the smart access point 830 for a control service. For instance, in a step 9, the service list shown in FIG. 5 may be provided to the user 810 as an icon type representing the virtual objects of the IoT device 840. The user 810 may request the smart access point 830 for a control service to control the IoT device 840, using the provided icon shown in FIG. 6.
In a step 861, the smart access point 830 may request the IoT devices 840 for IoT control. In a step 862, the IoT devices 840 may respond to the smart access point 830 for the IoT control. For instance, when the IoT device 840 is a boiler or a device for controlling a boiler, the control service requested by the user 810 may be a control service for heightening a setting temperature of a boiler. At this time, the smart access point 830 may request the IoT device 840 to heighten a setting temperature of the boiler (the IoT control request). The IoT device 840 may heighten a setting temperature of the boiler based on the IoT control request and respond to the smart access point 830 (IoT control response) in a step 862.
In a step 863, the smart access point 830 may renew or log an instance state. For instance, when the IoT device 840 heightening the setting temperature of the boiler from 15° C. to 18° C. based on a request, the smart access point 830 may renew a state of an instance corresponding to the IoT device 840 and change a current setting temperature into 18° C., such that such change of the setting temperature can be recorded for logging.
In a step 864, the smart access point 830 may respond to the user for the control service. For instance, the smart access point 830 may notice to the user 810 that the setting temperature of the boiler is changed into 18° C.
FIG. 9 is a diagram illustrating one embodiment of an operation process for a method for providing a web-based service according to exemplary embodiments of the disclosure.
In a step 911, a smart access device may broadcast information on instance running (information on whether an instance is implementing) and information on usage of a space IoT control function.
In a step 912, the smart access point checks whether a user terminal is linked to a wireless network. When the user terminal is linked, the smart access point may implement a step 913. When the user terminal is not linked, the smart access point may re-implement the step 911.
In a step 913, the user terminal may request a list of services useable on the smart access point. For instance, the user terminal is linked to a wireless network and then it may request a service list of the smart access point through a redirection function.
In a step 914, the smart access point may grasp the user's permissions and implement a step, once the user's permissions are grasped.
In a step 915, the smart access point may create a list of virtual objects which can be provided based on a web and respond (create a web page). For instance, the smart access point may provide an URL accessible to the created web page to the user terminal.
In a step 916, the user terminal may request the smart access point for user control. Such the request of the user terminal may be generated through a web page on the web directly.
In a step 917, the smart access point may implement a step 918 or a step 921 based on the permissions of the user's service implementation. For instance, when the user's permissions for running the service are certified, a step 918 may be performed. When the user's permissions for running the service are not certified, a step 921 may be performed.
In the step 918, the smart access point may request the IoT device for control. For instance, the smart access point may generate a request message for controlling the IoT device based on the user control requested from the user terminal and send the generated message to the IoT device.
In a step 919, the IoT device may respond to the request of the smart access point. For instance, the IoT device may perform an operation according to the request of the smart access device and send a responding message containing the result of the operation to the smart access point.

FIG. 10 is a diagram illustrating one embodiment of a method for providing an intent-based service according to exemplary embodiments of the disclosure. FIG. 10 shows a user 1010, a manager 1020, a smart access point (Smart AP, 1030) and an IoT device (IoT Device, 1040). The user 1010 and the manager 1020 may be the same subject or different subjects. Substantially, the user 1010 and the manager 1020 may mean the device used in accessing the user 1010 and the manager 1020 to the smart access point 1030. A plurality of IoT devices 1040 may be provided.
A method for providing services according to this embodiment may interpret and process the user's intent for a device possessed by the user 1010 or a space IoT environment on the services. The user's device access the smart access point 1030 and receive a list of accessible intents from the smart access point 1030. When intent is generated in the user device based on list of the intents, the user device may send a service control request to the smart access point 1030. The smart access point 1030 may process the user's service control request, with interworking with the IoT devices 1040. As mentioned hereinabove, “intent” used in the specification may mean the data including attributes, actions, types and/or values for identifying and/or controlling the IoT devices based on the users' intents.
In a step 1050, the manager 1020 may deploy a virtual object (VO) of an IoT device 1040 accessible to the smart access point 1030 in the smart access point 1030. For instance, the manager 1020 may approach the smart access point 1030 to progress the deployment of the virtual object. The smart access point 1030 may deploy the virtual object in a step 1051-1.
In a step 1052, the smart access point 1030 may progress the interworking with the IoT device 1040. At this time, the IoT device 1040 may interwork, corresponding to the virtual object deployed on the smart access point 1030.
In a step 1053, the smart access point 1030 may broadcast instance running of the virtual object and information on the presence of the space IoT control function. For instance, the smart access point 1030 may broadcast a message containing the information on the presence of the functions mentioned hereinabove (a space IoT controllable message which will be described later) to the linked terminals.
In a step 1054, the user 1010 may access the smart access point 1030 wirelessly. In a step 1055, a wireless network may be connected between the user 1010 and the smart access point 1030.
In a step 1056, the smart access point 1030 may allow the user 1010 to access the wireless network and identify and certify the user information.
In a step 1057, the smart access point 1030 may send information for space IoT control to the user 1010. The information for the space IoT control may be a list of information associated with the IoT device 1040 and intents including addresses and authenticators.
In a step 1058, the user 1010 may receive the information for controlling the space IoT from the smart access point 1030 and register the intents.
In a step 1059, the user 1010 may respond to the smart access point 1030 with respect to the reception of the information for controlling the space IoT.
In a step 1060, the smart access point 1030 may wait for the response from the user.
In a step 1061, the user 1010 may perform matching based on the user's intent. For instance, for the user's intent to heighten a stetting temperature of a boiler, the user 1010 (substantially a device possessed by the user 1010 as mentioned hereinabove) may search for an intent matching the user's intent out of registered intents. At this time, the user's intent may be determined based on the user's current input or the user's former input (e.g., schedule information).
In a step 1062, the user 1010 may request for a space IoT control service. For instance, the user 1010 may send a message for requesting the space IoT control service (e.g., message containing information of “heighten a setting temperature of the boiler managed by the IoT device 1040 by 3° C.) to the smart access point 1030, using the control information including the intent matched in the step 1061, the addresses and the authenticators.
In a step 1063, the smart access point 1030 may request the IoT device 1040 for IOT control. In a step 1064, the IoT device 1040 may respond to the IoT control of the smart access point 1030. For instance, when the IoT device 1040 is a boiler or a device for controlling a boiler, the smart access point 1030 may request the IoT device 1040 to heighten a setting temperature of the boiler in the step 1063. After heightening the setting temperature of the boiler according to the IoT control request, the IoT device 1040 may respond to the smart access point 1030 in the step 1064 (IoT control response).
In a step 1065, the smart access point 1030 may perform renewal and logging of an instance state. For instance, when the IoT device 1040 heightens the setting temperature of the boiler from 15° C. to 18° C., the smart access point 1030 may renew a state of an instance corresponding to the IoT device 1040 and change a current setting temperature into 18° C. Such change in the setting temperatures may be recorded and logging may be performed.
In a step 1066, the smart access point 103 may send a response to a IoT control service to the user 1010. For instance, the smart access point 1030 may notice to the user that the setting temperature of the boiler is changed into 18° C. according to the user's request.
FIG. 11 is a diagram illustrating one embodiment of an operation process for a method for providing an intent-based service according to exemplary embodiments of the disclosure.
In a step 1111, a smart access point may broadcast instance running and information on usage of a space IoT control function.
In a step 1112, the smart access point may check access of the user terminal to a wireless network. When the user terminal is linked to the wireless network, a step 1113 may be performed. When the user terminal is not linked, the step 1111 may be re-performed.
In a step 1113, the smart access point may certify the user permissions. At this time, the access point may perform a step 1114 when the user permissions are certified and may re-perform the step 1112 when the user permission is not certified.
In a step 1114, the smart access point may transmit information for the space IoT control, corresponding to an individual user permission certification to the user terminal.
In a step 1115, the user terminal may request the smart access point for the space IoT control. For instance, the user terminal may identify various users' intents based on the IoT control information transmitted from the smart access point and send a message for the space IoT control request to the smart access point to control the IoT device.
In a step 1116, the smart access point may certify the permissions for the user's implementation and perform a step 1117 or a step 1020 based on presence of the permission certification for the user's implementation. For instance, when the permissions for the user's implementation are certified, the step 1117 may be performed. When the permissions are not certified, the step 1120 may be performed.
In a step 1117, the smart access point may request the IoT device for control. For instance, the smart access point may generate a message for requesting the control of the IoT device based on the space IoT control requested by the user terminal and send the generated message to the IoT device.
In a step 1118, the IoT device may respond to the request of the smart access point. For instance, the IoT device may perform operations according to the request of the smart access point and send a message to the smart access point in response to the result of the performance.
In a step 1119, the smart access point may perform renewal and logging of an instance state.
In a step 1120, the smart access point may respond to the user's space IoT control request. For instance, the smart access pint may send to the user terminal the information showing that the user's space IoT control request is performed normally and the information about the instance state changed based on the result of the performance. Alternatively, the smart access point may send to the user terminal the information showing that there are not permissions for the user's implementation, when the certification of the permissions for the user implementation is failed in the step 1116.
In the present embodiment, the permission certification and the running certification may be identified, using a security certification of a general wireless router or registration of MAC provided in the user terminal. In addition, the space IoT control information may be provided, with a web internet type.
FIG. 12 is a diagram illustrating another embodiment of a method for providing an intent-based service according to exemplary embodiments of the disclosure. FIG. 12 shows a user 1210, a manager 1220, a smart access point (Smart AP, 1230) and an IoT device (IoT Device 1240). The users 1210 and the manager 1220 may be the same subject or different objects.

In a step 1257, the smart access point 1230 may send information for a space IoT call to the user 1210. Different from the space IoT control information shown in FIG. 10 including the control information associated with the IoT device 1040 and the list of the intents having the addresses and the authenticators, the space IoT call information shown in FIG. 12 may include call addresses (information on the addresses used in calling a web intent) and schemas (e.g., parameters required by the calling of the web intent). The user 1010 shown in FIG. 10 may identify an intent matching the user's intent from the list of the intents and request the space IoT control based on the identified intent. In contrast, the user 1210 shown in FIG. 12 may send the user's intent to the smart access point 1230 as it is, simply using the space IoT call information. For that, in a step 1258, the user 1210 may receive the information for the space IoT calling. A step 1259 may mean a process that the user 1210 identifies an idea of the user's intent. When the user's intent is generated, the user 1210 may transmit the user's intent to the smart access point 1230 in the step 1260.
In a step 1261, the smart access point 1230 may interpret the user's intent and match the interpreted intent with a virtual object. For instance, the smart access point 1230 may search and match a corresponding virtual object to the IoT device 1240 the user desires to control, using the information including attributes, actions, types and/or values contained in the user's intent. At this time, the smart access point 1240 may understand the user's intent based on ontology and/or semantic schema proper to characteristics of the user's intent and progress mapping with a virtual object providing a corresponding service.
In a step 1262, the smart access point 1230 may request the IoT device 1240 for IoT control. In a step 1263, the IoT device 1240 may respond to the IoT control of the smart access point 1230.
In a step 1264, the smart access point 1230 may perform renewal and logging of an instance state.
In a step 1265, the smart access point 1230 may send a response to the processing of the user's intent to the user 1210.
In the embodiment, the user's permission certification may be grasped, using security certification of a general wireless router or presence of MAC registration of the user terminal.

In a step 1359, the smart access point 1330 may analyze the user profile.
In a step 1360, the smart access point 1330 may request the IoT device 1340 for IoT control. In a step 1363, the IoT device 1340 may send a response to the IoT control to the smart access point 1330.
In a step 1361, the smart access point 1330 may perform renewal and logging of an instance state.
According to the present embodiment, the smart access point 1330 provides services according to the profile for an individual profile actively, even without an auxiliary instruction from the user 1310. For instance, when determining that the corresponding user are sensitive to heat based on the result of the user profile analysis (based on a history of sensing or actions for an existing boiler or air conditioner recorded in association with the corresponding user), the smart access point 1330 may control related IoT devices to turn on an air conditioner or lower a setting temperature of a boiler automatically based on the current temperature (based on temperature information provided from a temperature sensor). Alternatively, the smart access point 1330 may expect a possibility of generating a special event for each device based on a history of events. For instance, when determining that the user 1310 turns on the lightening at about 19:35 hours (1310) everyday based on the event history after the user 1310 approaches at 19:35, the smart access point 1330 may turn on the lightening even without the user's auxiliary instruction.
In a step 1362, the smart access point 1330 may receive a user's intent. At this time, the step 1362 may correspond to the step 1060 shown in FIG. 12 and the smart access point 1330 may interpret the user's intent to match the user's intent with a virtual object, such that services according to the user's intent may be further provided.
