1, the U-City system 100 includes a system unit 120. The system unit 120 includes an information transfer unit 121, an information collection unit 122, A context inference unit 123, a linkage processing unit 124, a GIS information storage unit 125_1, and an object information storage unit 125_2. The system unit 120 may also interface with at least one device associated with an object in the U-City system 100. The at least one device may include an active device 111 such as a sensor, an RFID, and a passive device 112 such as a KIOSK, a wall, a mobile, and a PC. The U-City system 100 performs an operation of actually connecting an actual object with a service inside and outside the system. For example, when the system unit 120 connects with one or more internal and external services 131 and 132 Is shown in Fig. The services 131 and 132 are located in the U-City system 100 and provide services to the objects or services located outside the U- (For example, existing public institutions, etc.).

A situation indicates a state of an entity existing in the world, and a situation information indicates information defined by characterizing the situation. In a ubiquitous computing environment, context information represents the state of an object (e.g., a user / object) or information of an object, and includes, as main factors of context information, an identifier, a location / direction / (Status / Activity) and Time (Time). Using such contextual information, it is possible to deduce additional information, which enables a wider assessment of the situation. The U-City system 100 according to an exemplary embodiment of the present invention detects a change in a situation and performs active and passive responses thereto. As an example of an active response, a system can be configured to automatically perform an action when a new situation or situation changes, and as an example of a passive response, information related to the situation change can be provided to the user, So that the information can be kept available for use.

In the U-City system 100 shown in FIG. 1, the information delivering unit 121 receives status information from the devices 111 and 112 related to the object, processes the received status information, To the inside of the system 100. To this end, the information transmitting unit 121 receives the status information via the interface with the active device 111 such as a sensor or an RFID or transmits the status information via the interface with the passive device 112 such as KIOSK, Wall, . When the status information is received through the interface, the information processing operation can be performed prior to transmitting the status information to the system. As an example of the information processing operation, authentication is performed to verify the suitability of a device or an object, or only when context information is changed through a filtering operation, the context information is stored in the U- And the like can be performed. In addition, a data conversion operation is performed on the status information received from the various devices to convert the data into a format of a format used in the U-City system 100.

The information collecting unit 122 collects various information related to objects from the inside and / or the outside of the U-City system 100, and stores the collected information. In addition, in terms of information management such as collecting and storing the information, object management functions such as storing information for each object or loading stored information are performed. In addition, the information collecting unit 122 can perform a function of managing the time and the period when collecting information from the inside and / or the outside of the U-City system 100, To the GIS (Geographic Information System) information.

The situation inferring unit 123 may use the context information received through the information delivering unit 121 and at least one information related to the objects provided in the U- Lt; RTI ID = 0.0 > and / or < / RTI > That is, additional information is inferred using at least one piece of information related to the object and the object information. For example, by performing inference operations using previous and current context information of an object, it is possible to predict current and subsequent situations of the object, and to predict the current state and the subsequent state of the object, Or may provide services, and link services related to the services according to the prediction results.

In addition to the context information received through the information transfer unit 121, at least one piece of information is further used for the reasoning operation. As an example, the past state information of the object received may be used to analyze a history related to an object's status pattern. In addition to the specific history of the object, one or more objects can be defined as one object group, and the rule associated with the unique situation pattern of each object group can be analyzed. The context inferring unit 123 may perform the inference operation using at least one of the history information of the object and the general rule information of the object group to which the object belongs. As an example, using the context information received through the information transfer unit 121 and the history information related to the context pattern of the object, it is possible to infer the subsequent situation of the object, and according to the inference result, Or may perform a service linking operation so that the service according to the optimal information operates.

On the other hand, when the previous context information of the object is not sufficiently stored with respect to the context pattern of the object, the above reasoning operation may be impossible or its accuracy may be lowered. To this end, the U-City system 100 according to an embodiment of the present invention may use the history information of the object and general rule information of the object group for the reasoning operation by a hybrid method. If the previous context information of the object is not sufficiently stored, the object group to which the object belongs is determined, and the general rule information of the determined object group is used for the reasoning operation. The object group can be grouped by dividing each object by age, gender, location, etc., and the rule information is analyzed for each object group, so that more context information can be used for reasoning operation.

The linkage processing unit 124 performs an operation of linking the services 131 and 132 inside and outside the U-City system 100 using the speculation result of the context inferring unit 123. [ As an example, referring to the speculation result of the context speculation unit 123, it can be determined which service is to be provided currently or later, and providing information on the object according to the speculation result The object can be actively associated with the services 131 and 132 inside and outside the U-City system 100. [ To this end, the reasoning result may be provided to the service 131 or 132 related to the object besides being provided to the object. The object can easily select any of the optimal situations analyzed related to the object using the reasoning result. Also, the services 131 and 132 related to the object can grasp the access of an object related to the object by using the reasoning result and use it for a preparation operation for providing a corresponding service.

Meanwhile, the U-City system 100 may include a storage unit for storing at least one information. For example, the U-City system 100 may include a GIS information storage unit 125_1 for storing GIS information, And an object information storage unit 125_2. The location information of the object can be generated by linking the GIS information stored in the GIS information storage unit 125_1 with the context information of the object.

And detects whether a change has occurred in the context information related to the object through the filtering operation. And status information can be selectively provided to the data conversion unit 121_4 according to the detection result. For example, if no change is made to the situation information, the situation information is prevented from being provided to the data conversion unit 121_4. On the other hand, if a change is made to the situation information, . The data conversion unit 121_4 performs data conversion before transmitting the context information provided from the various devices to the context inference unit so that the context information from various devices can be converted into the same format data .

On the other hand, the device management unit 121_5 checks the status of various devices in the U-City system 100 and confirms whether there is an abnormality. If appropriate status information is not received from the devices, the active monitoring unit 121_6 requests information delivery to the devices, and receives and processes responses of the devices. When the screen conversion unit 121_7 needs to transfer various information generated in the U-City system 100 to the user's device, the screen conversion unit 121_7 converts various information in the U-City system 100 To the device. If the data formats of the various devices are different from each other, the screen conversion unit 121_7 may further perform a data conversion operation to provide the converted data to the devices.

The analyzed history information is provided to the inference engine unit 1233 and used for inference operation.

On the other hand, the situation information management unit 1231_2 controls deletion and / or additional operations of the previous situation pattern of the object. That is, when the previous status patterns of the objects used for analyzing the history information are stored unlimitedly, a problem of capacity increase of the storage unit arises. Therefore, the situation information management unit 1231_2 may update the status information And deletes or adds the situation information. As an example, it is possible to perform a deletion operation on situation information before a predetermined period or a small number of context information which largely deviates from a pattern of an object, while context information received at present and immediately before is additionally stored Can be performed. For the above operation, the result of the reasoning operation of the inference engine unit 1233 corresponding to the current situation information and / or the result of linking the system according to the reasoning result may be fed back to the situation information management unit 1231_2 .

Meanwhile, the rule management unit 1232 identifies object groups including at least one object, and manages general rule information of the object groups for each object group. For this, the rule management unit 1232 may include a profile management unit 1232_1 and a group rule management unit 1232_2. The profile management unit 1232_1 manages the profile of each object group. For example, the plurality of objects are classified into one or more object groups according to characteristics such as age, gender, and location, and the profile management unit 1232_1 manages profiles related to the characteristics of the object groups. Accordingly, the inference engine unit 1233 determines the object group to which the object belongs, and generates a signal according to the determination result. The group rule management unit 1232_2 analyzes the general rule information on the object group using the determined status information of the object group. As an example, general rules of an object group can be analyzed using the status information of the object group stored in the object information storage unit 125_2. The group rule management unit 1232_2 analyzes the general rule information of the object group to which the object belongs in response to the request of the reasoning engine unit 1233 and provides the analyzed rule information to the reasoning engine unit 1233.

As described above, the history information of the object may be analyzed first, and the analysis result may be combined with the context information of the object to perform the inference operation. If the past state information of the object is not sufficiently stored and analysis of the object's history information is impossible or error probability is high, a reasoning operation is performed using general rule information of the object group to which the object belongs . In the reasoning operation as described above, history information of at least one other object related to the object may be further used.

The linkage management unit 1233_3 receives the speculation result of the speculation unit 1233_2 and generates a signal for linking with the services inside and outside the U-City system 100 in response thereto. The signal is provided to the linkage processing unit 124 so that the object and the service of the inside and the outside are linked with each other in accordance with the change of the situation of the object. The reasoning result of the reasoning unit 1233_2 and the system linkage result of the linkage management unit 1233_3 may be fed back to the history management unit 1231 or the rule management unit 1232, May be used for operations to manage information or manage group rules.

Meanwhile, as described above, the situation inferring unit 123 may further include a risk management unit 1234 for detecting a risk of objects in addition to the reasoning operation related to the object and processing the objects. 4, the risk management unit 1234 is described in the contextual reasoning unit 123, but the present invention is not limited thereto.

The service linkage unit 124_2 performs the linkage data and the communication function for performing the actual service. When the linkage monitoring unit 124_3 performs the service in the form of convergence of the various services, the linkage monitoring unit 124_3 monitors the result of one service, And performs functions for calling different services according to the result values. On the other hand, the external organization interface unit 124_4 performs data communication with an external organization when the desired service is a service external to the U-City system 100. [

6 is a flowchart illustrating an operation method of a U-City system according to an embodiment of the present invention. According to the operation method of the U-City system as shown in FIG. 6, a step of receiving status information generated from at least one device related to an object is performed (S11). Processing of status information related to device authentication, filtering, and data conversion with respect to the received status information is performed (S12).

On the other hand, in addition to the reception and processing of the situation information, the U-City system manages information about objects in the U-City system and also manages information related to objects to be managed from devices inside and outside the system A collecting step is performed (S13). Although steps S11 to S13 are sequentially shown in Fig. 6, the step S13 may be performed prior to the reception and processing of status information S11 and S12.

Thereafter, in order to perform the context inference operation on the object on which the context information is received, the step of analyzing the history information of the object is performed (S14). In analyzing the history information, various previous and / or current context information of the objects stored in the U-City system is used. For example, when an identifier of an object is determined by the processing of the context information, history information related to a previous context pattern of the object is analyzed using context information related to the object. In addition, the objects may be classified into at least one group, and general rule information of the object group to which the object belongs is analyzed (S15). It is possible to detect a group to which an object belongs from an identifier of the identified object and to analyze general rule information corresponding to the object group using context information related to the object group.

The steps S14 and S15 may be used in accordance with the hybrid scheme. As an example, the history information of the object may be analyzed first to perform the contextual reasoning operation of the object. If the previous and / or current status information of the object is sufficiently included in the system, the history information of the object is analyzed. On the other hand, if the previous and / or current status information of the object is not sufficiently included in the system, the object group to which the object belongs is analyzed and the general rule information of the determined object group is analyzed.

When the analysis of the history information and / or the analysis of the general rule information is completed, the object inference operation is performed (S16). The analyzed history information and / or general rule information is used in performing the context reasoning operation. In addition to the above information, history information of at least one other object substantially related to the object or general rule information of an object group to which other objects belong may be further used.

When the above situation inference operation is performed and the result is generated, an operation of associating an actual service according to the inference result is performed (S17). According to the inference result, the service that the object is currently needed can be inferred, and an operation of associating the actual service with the object using the inference result is performed. Since the actual service is not a single service, but a fused service type in which a plurality of services are linked, an operation for controlling the service can be further performed.
