However, the present invention is not to be taken in a limiting sense for specific embodiments, it should be understood that the present invention includes all modifications, equivalents, and alternatives falling within the spirit and scope of the present invention. In the following description of the present invention, detailed descriptions of known functions and configurations which are deemed to make the gist of the present invention obscure will be omitted. Furthermore, the singular terms used in the specification and the claims should be generally interpreted to mean “one or more” unless otherwise stated. 
         [0016]    Hereinafter, preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings, wherein the same or corresponding components are denoted by the same reference numerals, and redundant description thereof will be omitted. 
         [0017]      FIG. 1  is a diagram of a system for configuring low-power wireless network according to an embodiment of the present invention. 
         [0018]    Referring to  FIG. 1 , the system for configuring low-power wireless network includes a mobile terminal  110 , a wireless device  120 , an apparatus  130  for managing a wireless device, and a network coordinator  140 . The mobile terminal  110  configures a new network identifier and a new device identifier to the wireless device. The wireless device  120  connects through a randomly connection with a managing target controlled by the apparatus  130  for managing a wireless device so that sensing information can be identified and control information for an operation can be transmitted. The apparatus  130  for managing a wireless device controls the operation of the managing target. The network coordinator  140  manages a low-power wireless network configured with the wireless device  120 . Hereinafter, the configuring low-power wireless network is described in detail with reference to the  FIGS. 2A to 2C . 
         [0019]      FIGS. 2A to 2C  are diagrams of explaining a configuring low-power wireless network according to an embodiment of the present invention. 
         [0020]    Referring to  FIG. 2A , a configuring network configured with the mobile terminal  110  and a wireless device is shown. A wireless device to configure a new network has an already known value through an initialization process using a certain method. The mobile terminal  110  becomes a known wireless network coordinator and searches for a wireless device existing around which is used in a low-power wireless network with a new wireless network setting value. In this case, the mobile terminal  110  identifies the searched wireless device using each device identifier. The mobile terminal  110  transmits a new network identifier, a new device identifier and a security setting value for security to be applied to each searched wireless device to the searched device. Here, the new network identifier is mutually same with the wireless device configuring a same low-power wireless network, but the new device identifier is mutually different from the wireless device configuring a same low-power wireless network. The wireless device  120  stores and reboots the new network identifier, the new device identifier and the security setting value transmitted from the mobile terminal  110 , applies the new network identifier, the new device identifier and the security setting value, and prepares to operate in the low-power wireless network. 
         [0021]    Referring to  FIG. 2B , a network registering a new identifier configured with the mobile terminal  110  storing the wireless network setting value which is newly set, the apparatus  130  for managing a wireless device, and the network coordinator  140  to a network coordinator is shown. The mobile terminal  110  transmits the new network identifier and the new device identifier applied to the wireless device to the apparatus  130  for managing a wireless device through a wireless LAN (WiFi). The apparatus  130  for managing a wireless device registers the new network identifier, the new device identifier and the security setting value received from the mobile terminal  110  to the network coordinator. In this case, the apparatus  130  for managing a wireless device may identify a managing target to be controlled using device identification information of the wireless device connected to the managing target. Furthermore, according to an embodiment, the mobile terminal  110  may directly register the new network identifier, the new device identifier and the security setting value to the network coordinator. Furthermore, according to an embodiment, the apparatus for managing a wireless device and the network coordinator may be physically implemented as a single apparatus. 
         [0022]    Referring to  FIG. 2C , a network configured with the wireless device  120  and the network coordinator  140  is shown. The network coordinator  140  configures a network according to the registered new network identifier by using wireless devices waiting to operate in the low-power wireless network applying the new network identifier, the new device identifier and the security setting value, and manages a network by identifying each wireless device using the new device identifier applied to each wireless device. 
         [0023]      FIG. 3  is a block diagram of a wireless device according to an embodiment of the present invention. 
         [0024]    Referring to  FIG. 3 , the wireless device  120  includes an initialization detecting unit  310 , an initial setting value storing unit  320 , a new setting value storing unit  330 , a system operating unit  340  and a wireless communication unit  350 . 
         [0025]    The initialization detecting unit  310  detects whether a network setting initialization command such as a network identifier and a device identifier is input from a user. In the following description, the network setting value means that the network setting value and the security setting value are included. 
         [0026]    The initial setting value storing unit  320  stores an initial network setting value such as a network identifier, a device identifier and a security setting value which are initially determined at a manufacturing stage of the wireless device. 
         [0027]    The new setting value storing unit  330  stores a new network setting value such as a new network identifier, a new device identifier determined by the mobile terminal. 
         [0028]    The system operating unit  340  controls an operation of the wireless device. Particularly, the system operating unit  340  stores in the new network setting value storing unit  330  when a new network setting value is received. The system operating unit  340  applies a new network setting value by rebooting the wireless device when a new network setting value is received. The system operating unit  340  initializes the applied new network setting value and applies an initial network setting value stored in the initial setting value storing unit  320 , when the network setting initialization command input is detected from the initialization detecting unit  310 . The system operating unit  340  transmits a control command for the managing target received from the apparatus for managing a wireless device to a managing target object. The system operating unit  340  transmits the information received from the managing target object to the apparatus for managing a wireless device. 
         [0029]    The wireless communication unit  350  connects the wireless device to the wireless network environment using the wireless communication method. 
         [0030]    Furthermore, the wireless device may include an input unit (not shown) receiving the network setting initialization command from a user. 
         [0031]      FIG. 4  is a diagram showing a wired connection for connecting a simple mobile terminal (which cannot provide a wireless coordinator function) to a wireless network module which can provide the wireless coordinator function, for a mobile terminal to provide the wireless coordinator function for providing a new wireless network setting function according to an embodiment of the present invention. 
         [0032]    Referring to  FIG. 4 , a mobile terminal  110  and a network coordinator  150  are connected through a wired cable  410 . The wired cable  410  connects the network coordinator  150  and the mobile terminal  110  through an OTG port (a micro USB) of the mobile terminal  110 . In this case, the mobile terminal  110  transmits the new network identifier, the new device identifier and the security setting value to be applied to the wireless device to the network coordinator  150 . The OTG port (the micro USB) is merely an example so that a communication port of the mobile terminal  110  capable of wired data communication may be used.

         [0037]    At step S 540 , the mobile terminal transmits the new network setting value including the new network identifier and the new device identifier applied to the wireless device to the network coordinator (SUN AP)  140  through a WiFi network using a wireless managing apparatus. The network coordinator  140  registers a new network setting value including a new network identifier and a new device identifier receiving from the mobile terminal for configuring a low-power wireless network. 
         [0038]    At step S 550 , the network coordinator  140  configures and manages a low-power wireless network configured with a wireless device to which the new network identifier is applied. In this case, the network coordinator  140  identifies each wireless device using the new device identifier applied to each wireless device. 
         [0039]    The embodiments of the present invention may be implemented in the mobile terminal and may be implemented as a mobile terminal readable recording medium. As shown in  FIG. 6 , a mobile terminal  600  may include at least one or more elements among one or more processor  610 , a memory  620 , a storage  630 , a user interface input device  640  and a user interface output device  650 , and they may communicate with each other through a bus  660 . Furthermore, the mobile terminal  600  may also include a network interface  670  for connecting to a network.
