Collaborative service device and providing method of the same}

The present invention relates to a cooperative service apparatus and a cooperative service providing method, and more particularly, when services from a plurality of devices are required to process a single service, services are more efficiently provided by designating an order or dependency therebetween. The present invention relates to a collaboration service device and a collaboration service providing method.

In order to process one service, several home appliances may need to work together. For example, a security service needs a surveillance camera, an infrared sensor, and a locking device to work together. In this way, multiple devices operate together in synchronization to provide a service.

Recently, home appliances have provided more and more various services according to various demands of consumers. In particular, a web service is also used to provide more various services. For example, when a recipe for a certain dish is not stored in an oven or a dish using another type of recipe is obtained from a web server, Can be set. Alternatively, there is a security camera that receives a photograph or montage data of a wanted person from the police station and compares it with a surveillance image obtained after storing it.

In order to perform such a diversified service, a service may be provided in one device such as an oven that receives data which is not stored through a network or the like and uses the same. However, in the case of the above-mentioned oven, if the recipes received from the web service are analyzed and other materials are needed, the data on the remaining materials stored in the refrigerator is transmitted, and if there is no material, the material is further requested. Complex services are in demand. There is a case that the entire service cannot be performed by a function that the device itself has in order to perform one service.

Therefore, in the case of services performed using multiple devices, it is necessary to know what other services or devices are needed, and to search for the availability of such devices, and there is no system in charge of such functions. If not, there is a problem that it is difficult to determine the order and dependencies between devices, so that efficient collaboration becomes difficult.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. However, embodiments of the present invention may be modified in various other forms, and the scope of the present invention is not limited to the embodiments described below. Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art.

1 is a block diagram of a collaboration service apparatus according to an embodiment of the present invention. The collaboration service apparatus 100 may include a collaboration service message receiver 110 which receives a collaboration service request message; A collaboration service dependency analyzer 120 for analyzing a dependency of the requested collaboration service; A collaboration service definition data generation unit 130 for generating definition data for the collaboration service to include the analyzed collaboration service dependency; A collaboration service definition data storage unit 140 for storing the generated collaboration service definition data; And an individual service request unit 150 for requesting an individual service to an external device connected to a network capable of providing a service defined in the definition data using the collaboration service definition data.

The collaboration service apparatus 100 includes a collaboration service message receiver 110 that receives a collaboration service request message. In the present invention, the 'collaboration service' refers to a service in which a plurality of devices cooperate with each other to provide one service. That is, the collaboration service is provided by combining individual services provided by an external device. For example, if the collaboration service is a security service, the external device may be a security camera, an infrared sensor, and a lock device. In other words, if the collaborative service of the collaborative service message is a security service, the collaborative service called a method service performs an object detection and image recording function service of a security camera, an infrared object detection function of an infrared sensor, and a door lock service of a locking device. It can be performed as a method service.

Once the request for the cooperative service is received, the cooperative service device 100 determines what the cooperative service is to provide the cooperative service.

The collaboration service dependency analysis unit 120 receives information on the collaboration service from the received collaboration service message and analyzes the dependency of the requested collaboration service. For example, a variety of services are defined on servers on the Internet, which can be serviced by a single device, or services that can be collaborated by multiple devices. Therefore, in order to determine a collaboration service that can be performed by several devices through collaboration, information such as the type of devices required for the collaboration service, a list of services required, dependency of each service, service providing order, and input / output relationship are needed. Therefore, the collaboration service dependency analysis unit 120 analyzes and determines the collaboration service in order to obtain information about the collaboration service.

It generates the definition data for the collaboration service by integrating various information including the analyzed collaboration service dependency. The collaboration service definition data is generated in the collaboration service definition data generator 130. The collaboration service definition data will be further described with reference to FIG. 2.

The collaboration service definition data storage 140 stores the generated collaboration service definition data. The collaboration service apparatus 100 is a network capable of providing a service defined in the collaboration service definition data through the individual service request unit 150 using the collaboration service definition data stored in the collaboration service definition data storage 140. Individual service can be requested from the connected external device. Alternatively, the collaboration service apparatus 100 requests the collaboration service definition data from another collaboration service definition data database (not shown) connected to the network in addition to the collaboration service definition data stored in the collaboration service definition data storage 140. This can be received and used. A description of the collaboration service definition data database connected to the network will be further described with reference to FIG. 3.

2 is collaboration service definition data 240 stored in a collaboration service apparatus according to an embodiment of the present invention. In particular, in the drawing, the collaboration service may set its name to "security service for going out." Therefore, the collaborative service definition data in FIG. 2 includes various pieces of information for performing the security service, which is a collaboration service.

The collaboration service definition data 240 may include a type of external device, a list of required individual services, an order of providing between individual services, dependencies between individual services, and input / output relationships. In detail, the collaboration service definition data includes order data for an external device, location data of the external device, name of the external device, name of the individual service provided by the external device, function of the individual service, dependent services dependent on the individual service, and individual. It may include at least one of a main service, an input list, and an output list that are main services. Among these, the external device name may further include instance information for distinguishing external devices to provide individual services when there are a plurality of external devices.

Referring to FIG. 2, the collaborative service definition data 240 is set for a service providing order and local or local location information on whether an external device is connected to the same local network as the collaboration service device or connected to the Internet. Mark as Global. For example, a door or a lighting may be connected to a local network such as a home network, but a police station may be connected to a global network such as the Internet.

Since there may be a plurality of external devices having the same function, the name of the external device includes instance information or property information for identifying which device together with the external device name. For example, since there are several doors that are external devices in Step 1, the door information is the instance information.

In the function item, the function of each device is shown. For example, the lights in step 2 are serviced to turn off. When the dependent service is dependent on the current service, for example, when the security camera of step 2 provides a motion detection service, the recording service of the security camera of step 3 is performed accordingly. Therefore, the recording service may be referred to as a service dependent on the motion detection service. In contrast, the main service is a main service of the current service. For example, the infrared detection service of the infrared sensor of step 2 is a service that precedes the recording service of the security camera of step 3.

Since the input list is a list of input types and devices and services from which inputs are input, the input list lists information from outside required for the service or trigger information for starting the service. The output list is the output type and the target device and service of the output.

The input list and output list will be described using the following example. If the user wants to go out, close the door and enter the password. The password inputted from the user is input data that requires the lock function of the switch service of the door and door apparatus. This locks out all lights. At this time, the input data of all the lights is the lock result of the door, door and switch. The output list is a list of results of the service, such as whether the door is locked or whether the method camera detects motion.

If the location of the external device is global, search for external devices and services using a proxy server.

The cooperative service device 300 is connected to the external devices 1 to 5 through the local network 360 and the internet 370 (310, 320, 330, 340, 350). The collaboration service definition data may be provided as the collaboration service definition database databases 380 and 390 separately on the local network 360 and the Internet 370. Accordingly, the collaboration service apparatus 300 may use the collaboration service definition data stored in the collaboration service definition data storage, and receive the collaboration service definition data from the collaboration service definition database databases 380 and 390 separately connected to the network. This can be used.

The external devices 310, 320, 330, 340, 350 may provide individual services 11, 12, 21, 22, 31, 32, 41, 42, 51, 52, respectively. Service functions 111, 112, 121, 122, 211, 212, 311, 312, 411, 412, 511, 512. The collaboration service apparatus 300 may provide the collaboration service through a request for selecting an external device having a required service function according to the collaboration service definition data and providing a service of the external device.

The collaboration service apparatus 300 plays a role of searching for devices and services necessary for collaboration, creating a schedule for function invocation, and promoting collaboration by a schedule. Searching for devices and services is provided by general web services or middleware such as UPnP and DPWS. The collaboration service device 300, however, provides input data necessary for calling and executing the retrieved device and service in the collaboration service definition. It provides the order and execution dependency information. Create a schedule for calling the service functions in order. Of course, the input data required for the call is used to call the function.

4 is a flowchart provided to explain a method of providing a collaboration service according to an embodiment of the present invention. According to an embodiment of the present invention, upon receiving the collaboration service request message (S400), the collaboration service definition data storage unit is searched (S410). If the definition data of the collaboration service is stored in the collaboration service definition data storage unit and does not exist (S420: N), the dependency of the collaboration service is analyzed (S430). Of course, this step analyzes and collects the information to create the collaboration service definition data as well as the dependency of the collaboration service. If the definition data is stored in the collaboration service definition data storage unit, it requests an individual service directly to an external device (S420: Y).

The definition data of the collaboration service is generated according to the analyzed collaboration service dependency and stored in the collaboration service definition data storage unit (S440). The collaboration service device requests a service provision to an external device connected to a network capable of providing a collaboration service according to the collaboration service definition data (S450). When requesting service provision, an external device may be searched through a network, and the service may be requested to the external device according to the order of provision between individual services.
