≪ Desc / Clms Page number 1 > METHOD AND APPARATUS FOR SHARING GLOSSARY-BASED M2M DEVICES &

The present invention relates to a method and an apparatus for sharing functions of M2M (Machine to Machine) devices connected to a network. More particularly, the present invention relates to a method and apparatus for sharing a function of a plurality of devices connected to the same local gateway By collecting possible function information, processing input signal defined by user and calculating new data or performing a new function to share the functions of devices, it is possible to easily extend service with existing services and to develop various new services And more particularly, to a gateway-based M2M devices function sharing method and apparatus that can easily support a gateway-based M2M device.

BACKGROUND ART [0002] With the rapid development of mobile communication and wireless communication technologies in recent years, the area has been expanded by communication between persons and objects, and further by machine-to-machine communication. Accordingly, a variety of M2M services are being developed, and the central server collects the function calculation data of the M2M devices through a network, analyzes / processes the data, and intelligently controls and controls them remotely. In addition, techniques for replacing the role of a central server by sharing functional calculation data between devices through a local network are also proposed.

Most of the currently implemented M2M services are based on a central server platform. That is, the central server primarily collects the function calculation data of the devices through the network, and secondarily analyzes / processes the intelligent remote control and remote device control. For example, the home monitoring system collects and processes information of various home devices in a home, and provides services such as real time power control and gas meter reading. In this type of business, devices, OS, middleware, etc. are optimized for the service and thus it is possible to provide stable service provision. However, since the hardware of the devices is optimized for the specific service of the silo type from the beginning, it is very difficult to use it for linking and expanding with other businesses. For example, it is very difficult to link the developed CCTV device to traffic speed violation control service optimized for crime prevention service. In order to combine the devices classified by these services, the level of the functional requirements to be performed by the central server platform is higher than that of the conventional one, and thus the cost of constructing the platform becomes higher or the development period becomes longer.

In addition to these problems, data traffic issues in transmitting data of all devices to a central server may be controversial in the future. Currently, the M2M business is at its early stage, so the size of the devices is small. However, if the market is matured and the number is expanded to more than 10 billion, there will be many problems in the business based on the central server platform. In addition, it may be rather inefficient to construct a central server that requires a lot of functions for a service provider who wants to perform a service business through a combination of small-sized devices.

Korean Patent Application No. 10-2009-0077874 (a method and apparatus for sharing functions of an external device via a complex network), Korean Patent Application No. 10-2009-0078439 (a function sharing method via a network, Device). Each of these technologies suggests ways to create additional new functions by sharing functional data between devices in a way that collects and processes all function data from existing central server. However, Korean Patent Application No. 10-2009-0077874 (method and apparatus for sharing functions of external devices through a complex network) suggests Device to Device communication basically. The interworking between the devices is performed through a specific device serving as a repeater, and then the intrinsic function calculation data is shared between the devices. In order to perform such a method, it is necessary to develop a separate module or firmware so as to perform a process for combining functions that are created by sharing the function calculation data of other devices with respect to each device. However, since the hardware and firmware of the existing device are designed and developed in a state optimized for the unique service, there is a great difficulty in loading the firmware that executes the shared function command to all the devices. In order to solve such a problem, Korean Patent Application No. 10-2009-0078439 (a function sharing method and apparatus via a network) discloses a technique in which a gateway collects function calculation data of each device, processes it, and executes various function commands It plays all the roles of. However, these conventional techniques describe in detail the procedure for sharing the function calculation data coming from each device in detail, but there is little information on how to create an additional service function using the shared data.

There is also a need for a technique for storing and managing profiles of functions that can be shared and function setting data and operation setting profiles of devices. Currently, the European Telecommunications Standards Institute (ETSI) has proposed a standard technology (ETSI TS 102 690: "Ch 9. M2M Resource Management and Procedures") for data transmission / storage / management between devices. However, the proposed technology of ETSI does not deal with the sharing function profile and the management method of operation setting profile of devices. Therefore, there is a need for an additional technology for efficiently managing these technologies, and further, a technology that allows a user to easily configure and dynamically reflect the functions of the devices into desired combinations.

A variety of M2M devices 110 on the local network may be available for a variety of monitoring purposes, but may include, for example, a blood pressure monitor, a thermometer, a heart rate monitor, a fire alarm, an intrusion alert, A motion sensor, a temperature sensor, a humidity sensor, a wind direction sensor, a pressure sensor, a gyro sensor, and an acceleration sensor for acquiring information on the surrounding situation such as a shop monitor, a facility monitor, and the like. Such devices 110 may be equipped with a DA (Device Application) based on an M2M protocol for communicating with the gateway 100 and receiving control thereof or performing necessary operations to calculate data.

In particular, the gateway 100 of the present invention collects each shareable function for a plurality of devices 110 connected thereto, and can operate a combination of functions desired by the user. Accordingly, it is possible for the devices 110 to calculate new data or to perform new functions, and to set detailed operation settings of the devices 110 (setting operation time of devices, setting operation order among devices , Operating conditions, etc.).

1, the gateway 100 includes a function request processing unit 101, a first storage 102, an inquiry setting processing unit 103, a second storage 104, a combination function module generation unit 105, An analysis unit 106, and an execution unit 107. [ In order to support the operation of the components of the gateway 100, a predetermined application (e.g., FunctionManager) is installed in the gateway 100. [ The basic concept of the operation of the gateway 100 will be described with reference to FIG.

The function request processing unit 101 requests the devices 110 communicating with the gateway 100 to send device state information including a function that can be shared among the devices (for example, a used application ID, a device ID, a function ID, a value type Data type), operation time, and the like), and stores a list of function information that each device can share in the first storage 102 (201). In addition, the function request processing unit 101 requests the devices 110 (for example, requesting function calculation data) according to the setting of the sharing function of the user or the like, collects resources for setting the sharing function operation from the devices 110, And stores it in the first storage 102.

3, the device status information (e.g., the used application ID, the device ID, the function ID, the value type (data type), the operation time and the like) including the above- eXtensible Markup Language (eXtensible Markup Language). 3, a device having a device ID 'motionsensor # 1' used by an application having an application ID 'motiondetection' is in a state of being able to be shared, and the device has a motion detection function corresponding to the function ID '# A1' . This function is '1' among various value types, and the operation time is '17:00 to 24:00'.

4 illustrates a container resource among resource tree structures in GSCL proposed by ETSI for data transfer and data storage and management between devices (gateway 100, device 110, and server 120) , A portion for managing a shared device state information resource (shareDevice) and a resource for setting a shared function operation (deviceSetting) in an existing resource type are added.

In accordance with the operation of the function request processing unit 101 as described above, the container of the first storage 102 stores device status information (e.g., used application ID, device ID, function ID, value type (Data type, operation time, etc.) (see FIG. 5) and a resource for setting a shared function operation corresponding to the shared function setting (for example, resources such as operation time, 6) is stored.

The inquiry setting processing unit 103 supports the sharing function setting and the combination function operation setting by the user as described above (202). The user can use the user interface such as a display device or a keypad provided in the inquiry setting processing unit 103 to display a list of shareable function information collected in the device 110 and stored in the first storage 102, (Operation time setting, operation requirement setting, transmission period setting, operation order setting, etc.) for making the device 110 perform a new operation by creating a new combination function combining the shared functions, Can be input.

The second storage 104 stores information on a combination function operation setting (e.g., operation time setting, operation requirement setting, transmission period setting, operation order setting, and the like) set in the container as described above.

The combination function module generation unit 105 refers to a list of shareable function information (device state information including a shareable function) stored in the first storage 102, and the like to the combination function operation setting defined by the user And determines the validation as to whether or not the actual execution is possible, and generates a corresponding combination function module (203).

The combination function analyzing unit 106 analyzes resources and the like for setting the shared function operation stored in the first storage 102 with respect to the combined function module thus created, and transmits the command to the executing unit 107 (204 ).

The execution unit 107 transmits the command of the combination function analysis unit 106 to the device 110 and controls the device 110 to operate according to the user's defined combination function operation setting. The device 110 performs commands according to commands for the corresponding combination function operation setting, for example, performs measurement, photographing, sensing, etc., and transmits the results to the service server 120 through the gateway 100, To the service server 120.

At this time, the GSCL container of the FunctionManager application installed in the gateway 100 has a URI (Uniform Resource Identifier), for example, 'http://m2m.kt.com/scls/kt_GSCL_001 / applications / FunctionManager / containers / motionSensor # 1 / shareFunction / '. Then, the device 110 targets the above URI, and the device ID, the application ID using the device, and the actual function calculation data are stored in the lower resource sharing function (shareFunction) of the GSCL container as the ' shareFunction id = "20110922120055"> 'Can be transmitted according to the standard as follows.

Hereinafter, the operation of the gateway 100 of the present invention will be described in more detail with reference to FIGS. 8 to 11.

FIG. 8 is a flowchart for explaining a process of requesting and collecting resources for sharing a function information list and a sharing function operation setting of the device of the present invention.

The function request processing unit 101 of the gateway 100 requests the devices 110 periodically or in response to a user's request through the inquiry setting processing unit 103 to perform a function 801/803 that can be shared among the devices (For example, a used application ID, a device ID, a function ID, a value type (data type), an operation time, etc.) from the respective devices 110 (802/804).

5) of the device state information (for example, the used application ID, the device ID, the function ID, the value type (data type), the operation time, etc.) including the shareable functions received in this way The list (shareable function information list) can be stored in the first storage 102 in association with the identifier of each device (S805).

In addition, the function request processing unit 101 periodically or in response to the user's sharing function setting request through the inquiry setting processing unit 103 and requesting the devices 110 (811/813) (812/814) and stores it in the first storage 102 (refer to FIG. 6) from the respective devices 110 (resources such as operation time, operation requirements, transmission period, 820).

The device state information including a function that can be shared among the devices (for example, a used application ID, a device ID, a function ID, a value type (data type), an operation time, etc.) in a container of the first storage 102 6) (see FIG. 6) of a list (shared function information list) and a resource (e.g., operation time, operation requirement, Is stored.

FIG. 9 is a flowchart for explaining a combination function operation setting and a process according to the present invention.

First, a user inquires a shareable function information list stored in the first storage 102, a resource for sharing function setting, etc. (901) through the user interface of the inquiry setting processing unit 103 as shown in FIG. 8, (For example, operation time setting, operation requirement setting, transmission period setting) for making one or more devices of the connected devices 110 perform a new operation by creating a new combination function composed of a combination of functions that can be shared , Operation order setting, etc.) (902).

At this time, rules for various functional operators (operators) as shown in FIG. 10 may be provided, and a user can input a combination function operation setting using such operator rules.

For example, when entering an operation sequence for a combination of functions that can be shared as a combination function operation setting, 'Equal (Device ID = # M1 -> (function ID = # A1, Value) Activation (Device ID = # S1 -> function ID = # C1) 'means' If the motion sensor senses motion, the CCTV camera should record the current scene'. In addition, when inputting the operation sequence for the combinations of the functions that can be shared as the combination function operation setting, 'Equal (Device ID = # M1 -> (function ID = # A1, Value) = 1) ID = # M1 -> (function ID = # A1, time), 20) -> Activation (Device ID = # S1 -> function ID = # C1) 'means that the motion detection sensor detects motion, When the detection time exceeds 20 o'clock, the CCTV camera may record the current scene.

When the user inputs the combination function operation setting and requests the execution of the combination function operation (910), the inquiry setting processing unit 103 sets the corresponding combination function operation (e.g., operation time setting, operation requirement setting, transmission period setting, In the second storage 104 (911).

The combination function module generation unit 105 first requests the combination function module generation unit 105 to the first storage 102 to execute a combination of the combination defined by the user Device state information (e.g., used application ID, device ID, function ID, value type (data type), operation time, etc.) including the shareable function of the device to perform the operation function included in the function operation setting (921), refers to it, determines validation as to whether or not actual execution is possible according to a predetermined rule (922), and determines whether or not the combination function module (for example, (930). ≪ / RTI >

It is determined that the received device state information is not valid when the currently disabled device, the data type, the operation time, etc. are incompatible with the performance of the operations according to the combination function operation setting, so that the combination function module may not be generated. For example, as shown in FIG. 11, when the operation time of the corresponding device is set to 15 o'clock in the combination function operation setting for a device having a working time of 17 o'clock to 21 o'clock, it becomes invalid.

If the combination function module generation unit 105 generates and transmits a corresponding combination function module for effective combination function operation setting (931), the combination function analysis unit 106 performs a combination operation function according to the combination function module (932) a resource (e.g., resources such as operation time, operation requirements, transmission period, and operation order) (see FIG. 6) for setting a shared function operation by requesting the first storage 102 for the first storage 102, (934), generates a corresponding command for a device to perform an operation function included in the combination function operation setting (combination function module) defined by the user, and transmits the command to the execution unit 107 (935).

The execution unit 107 transmits the command received from the combination function analysis unit 106 to the device 110 and controls the device 110 to operate according to the combination function operation defined by the user in operation 940. The device 110 performs commands according to commands for the corresponding combination function operation setting, for example, performs measurement, photographing, sensing, etc. and outputs the result to the service server (not shown) 120 or directly to the service server 120.

As described above, according to the method of sharing functions of M2M devices based on the gateway 100 of the present invention, by collecting each shareable function for a plurality of devices 110 and operating a combination of functions desired by the user, (Operation time setting of devices, operation order setting among devices, operation conditions, etc.) so that the device 110 can calculate new data or perform new functions, and can make additional functions , It can be easily extended to existing services and can expand the service and facilitate the development of various new services. For example, as described above, in order to generate an additional function of 'recording a video to a CCTV camera when motion (motion) is detected from a motion detection sensor', the user needs to set the operation time, Conditions and the like can be set in detail.

While the invention has been shown and described with reference to certain preferred embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
