Description

CONTROL METHOD AND CONTROL APPARATUS FOR PROVIDING COLLABORATIVE SERVICE}

The present invention relates to a collaboration service, and more particularly, to a control method and a control apparatus for a collaboration service.

Collaboration systems that provide collaboration services include master controllers and subcontrollers. The sub-controller generates unit collaboration service using the primitive service provided through the controlled controller, and the main controller generates the final collaboration service using the unit collaboration service provided through the sub-controller.

An example of a collaboration service is a home network. According to the home network, a server provides a user interface, and the user controls other devices in the home through the server's user interface. As the home network technology develops, an environment in which many controllers capable of controlling other devices in the home may exist in the home is being created. Such middleware technology defines that many devices can act as controllers. The user may control other devices in the home through a user interface provided by a plurality of devices.

Meanwhile, in order to provide a collaboration service suitable for a user, it is necessary to consider user preferences in a process of controlling the collaboration service. For example, one family member wants to listen to music while exercising. When the user operates the treadmill, the music player in the house is searched for. If there are several music playback devices in the house, a music playback device that provides the user's favorite music needs to be selected. However, it is technically difficult to automatically select a device preferred by the user without a separate operation of the user.

The technical problem to be solved by the present invention is to provide a control method and a control apparatus for a collaboration service that satisfies user preferences.

In a cooperative system including a master controller, a sub-controller, and a plurality of controlled controllers according to an aspect of the present invention, a method of controlling a sub-controller may include acquiring user information to be provided with a cooperative service, and each of the plurality of controlled controllers is provided. Generating a plurality of coordination instances by combining a plurality of primitive services, calculating a correlation with the user information for each coordination instance, and providing the coordination instance with the highest correlation to the main controller. Include.

The control device for providing a collaboration service according to an aspect of the present invention is a control unit for generating a plurality of coordination instances by combining a user recognition unit for obtaining user information to be provided with the collaboration service, a plurality of primitive services, the plurality of A selection unit for selecting a coordination instance having the highest correlation with the user information from the coordination instance, and an output unit for transferring the selected coordination instance to a controller of a higher layer.

Custom collaboration services can be provided without user intervention. A service suitable for a user who receives a collaboration service may be provided based on owner information of a controlled controller.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. In the drawings, parts irrelevant to the description are omitted in order to clearly describe the present invention, and like reference numerals designate like parts throughout the specification.

Throughout the specification, when a part is said to "include" a certain component, it means that it can further include other components, without excluding other components unless specifically stated otherwise.

1 is a structural diagram of a collaboration system according to an embodiment of the present invention.

Referring to FIG. 1, the cooperative system includes a main controller 100, at least one sub controller 110, and at least one controller 120.

The controller 120 is a device that provides a primitive service (PS). For convenience, the controller 120 is represented by PS1 to PS9 in the drawings. The sub-controller 110 configures the unit cooperative service by combining the primitive services provided by the control unit 120. The master controller 100 configures the final collaboration service using the unit collaboration service provided by the sub-controller 110.

The sub controller 110 searches for and executes the primitive service of the controller 120 through L1 through L9. The master controller 100 searches for and executes the unit cooperative service of the sub-controller 110 through C1 to C3. Here, C1 to C3 and L1 to L9 are networking interfaces.

On the other hand, the sub-controller 110 generates at least one coordination instance (Coordination Instance) to configure a unit collaboration service. That is, the sub-controller 110 generates at least one coordination instance performing the same function by using a combination of primitive services. The sub-controller 110 stores the generated coordination instance, selects one of the stored coordination instances, and provides the selected coordination instance to the main controller 100.

For example, the controller 5 providing the primitive service 5, the controller 6 providing the primitive service 6, and the controller 7 providing the primitive service 7 are all music reproduction devices. The sub-controller 110 configures the controller 4 and the controller 5 as the coordination instance A, configures the controller 4 and the controller 6 as the coordination instance B, configures the controller 4 and the controller 7 as the coordination instance C It may store and provide a unit collaboration service of one selected from the coordination instance A, the coordination instance B, and the coordination instance C to the master controller 100.

Here, the sub-controller 110 may select which coordination instance from among a plurality of coordination instances to provide to the main controller 100. When the sub-controller 110 selects the coordination instance in consideration of user preferences, the user can be provided with a satisfactory collaboration service.

For example, controlled device 5, controlled device 6, and controlled device 7 are all music playback devices, each music playback device is owned by each family member, and each music playback device provides a media player service and a media server service. If a son, one of the family members, wants to exercise while listening to music, the treadmill and the music player may provide a cooperative service. At this time, if the music reproducing apparatus owned by the son provides the music file, a cooperative service suitable for the son's taste may be provided.

Hereinafter, a method in which the sub-controller 110 selects a coordination instance through user recognition will be described.

2 is a block diagram of a sub controller participating in a collaboration service according to an embodiment of the present invention.

Referring to FIG. 2, the sub controller 200 includes a sensor unit 210, a user recognition unit 220, a control unit 230, a storage unit 240, a selection unit 250, and an output unit 260. .

The sensor unit 210 detects a user. For example, the sensor unit 210 may be at least one of a camera, a biosensor, a radio frequency identification (RFID) reader, and a voice recognizer. That is, the sensor unit 210 may detect a user's face through a camera or detect a user's fingerprint through a bio sensor. The sensor unit 210 may detect an RFID card possessed by a user through an RFID reader or detect a user's voice through a voice recognizer.

The user recognition unit 220 extracts data of the user sensed through the sensor unit 210 and recognizes the user using the extracted data. For example, the user recognizer 220 may compare previously stored user information with data of the user sensed through the sensor 210 and select user information having the highest correlation with the user's data.

The controller 230 generates at least one coordination instance by combining a plurality of controlled units controlled by the sub-controller 200.

The storage unit 240 stores at least one coordination instance generated by the controller 230 and transmits the stored at least one coordination instance to the selection unit 250.

The selector 250 selects a coordination instance suitable for the user by using the user information received from the user recognizer 220 and the information included in the coordination instance received from the storage 240.

The output unit 260 provides the main controller with the coordination instance selected by the selector 250.

3 is a flowchart illustrating a control method of a sub-controller participating in a collaboration service according to an embodiment of the present invention.

Referring to FIG. 3, the sub controller acquires user information (S300). For example, a user may be detected by using a sensor, and the user information for receiving a collaboration service may be extracted by comparing with the previously stored user information. The user information may be, for example, a user ID.

The sub-controller generates at least one coordination instance (S310). The coordination instance may be generated by a combination of a plurality of controlled units controlled by the sub-controller. The coordination instance includes at least one primitive service list. For example, when the sub-controller controls the control unit 1, the control unit 2, the control unit 3, the coordination instances that can be created are {PS1, PS2, PS3}, {PS1, PS2}, {PS1, PS3}, etc. Can be.

The coordination instance may perform some same function. Each coordination instance is actually a list of available primitive services, how each primitive service runs, the IP address of the device that provides each primitive service, the universal unique identifier (UUID) of each primitive service, and the device that provides each primitive service. Owner information, a weight of each primitive service, and the like.

The sub-controller calculates a correlation between the user information and the coordination instance (S320). For example, the coordination instance may include owner information of a device providing a plurality of primitive services constituting each coordination instance. Therefore, the sub-controller can compare the user information and owner information for each coordination instance, and reflect the comparison result in the score.

The sub-controller selects the coordination instance having the highest correlation with the user information (S330), and transmits the selected coordination instance to the main controller (S340).

Hereinafter, a method in which the subcontroller calculates a correlation between the user information and the coordination instance and selects the coordination instance based on the calculation result will be described in detail.

4 illustrates a method of selecting a coordination instance suitable for a user by a selection unit of a sub-controller participating in a collaboration service according to an embodiment of the present invention.

Referring to FIG. 4, each coordination instance is a unique identifier (UUID) of each primitive service, an IP address of a device providing each primitive service, a name of each primitive service, and an owner of a device providing each primitive service. Information (for example, owner ID) and the like.

On the other hand, the selection unit 400 of the sub-controller includes a calculation unit 410 and the selection unit 420. The calculation unit 410 calculates a correlation using user information recognized by the sub-controller and owner information (1, 2) of a device providing a plurality of primitive services included in each coordination instance. The selection unit 420 selects the coordination instances ③ and ④ having the highest correlation calculated by the calculation unit 410, and transfers them to the main controller through the output unit.

In detail, the calculation unit 410 may calculate a correlation using the following equation.

Here, n is the number of primitive services constituting each coordination instance. The calculation unit 410 compares the owner information and the user information of the device providing the primitive service for each coordination instance. If the owner and user information match, the score is 1; if not, μ is added, and the scores for all the primitive services included by the coordination instance are summed. The calculation unit 410 informs the selection unit 420 of the coordination instance with the highest summed score.

The selection unit 420 selects the coordination instance with the highest total score and transmits the selected coordination instance to the main controller.

5 illustrates a method of selecting a coordination instance suitable for a user by a selection unit of a sub-controller participating in a collaboration service according to another embodiment of the present invention. Hereinafter, the description overlapping with the description of FIG. 4 will be omitted.

Referring to FIG. 5, each coordination instance is a unique identifier (UUID) of each primitive service, an IP address of a device providing each primitive service, a name of each primitive service, and an owner of a device providing each primitive service. In addition to the information (e.g., owner ID), it further includes the weight ratio of each primitive service.

The calculation unit 510 of the sub-controller 500 may calculate the correlation using the following equation.

Here, n is the number of primitive services constituting each coordination instance. The calculation unit 510 compares the owner information and the user information of the device providing the primitive service for each coordination instance. If the owner information and the user information match, 1 is scored, and if they do not match, the score is given as μ, and the weighted score of each primitive service is summed. The calculation unit 510 delivers the coordination instance with the highest sum score to the selection unit 520, and the selection unit 520 delivers the coordination instance with the highest summed receipt to the main controller.

Therefore, the coordination instance having the most primitive service related to the user of the collaboration service can be selected, and the user can be provided with a satisfactory collaboration service.
