     According to an embodiment, when performing communication in a form in which each of the plurality of gateways  200 - 1  and  200 - 2  receives a communication signal periodically transmitted by the wireless communication terminal  300 - 1 ,  300 - 2 , or  300 - 3 , a range of the communicable areas RG 1  and RG 2  may be determined by a range within which a communication signal of the wireless communication terminal  300 - 1 ,  300 - 2 , or  300 - 3  may reach or a signal transmission level of the wireless communication terminal  300 - 1 ,  300 - 2 , or  300 - 3 . 
     For example, when communication is performed through a beacon included in the wireless communication terminal  300 - 1 ,  300 - 2 , or  300 - 3 , the communicable areas RG 1  and RG 2  may be determined by a range within which a Bluetooth signal transmitted by the beacon may reach.

     Each of the plurality of sound collecting devices  220 - 1  and  220 - 2  may communicate with the gateway  200 - 1  or  200 - 2  corresponding to each of the plurality of sound collecting devices  220 - 1  and  220 - 2 , and may transmit collected sound data to the corresponding gateway  200 - 1  or  200 - 2 . For example, the first sound collecting device  220 - 1  may transmit collected sound data to the first gateway  200 - 1 , and the second sound collecting device  220 - 2  may transmit collected sound data to the second gateway  200 - 2 . 
     According to an embodiment, the first sound collecting device  220 - 1  may collect sounds within the range of the communicable area RG 1  of the first gateway  200 - 1 , and the second sound collecting device  220 - 2  may collect sounds within the range of the communicable area RG 2  of the second gateway  200 - 2 . 
     Image data collected by the image collecting device  210 - 1  or  210 - 2  and sound data collected by the sound collecting device  220 - 1  or  220 - 2  may be used to determine an abnormal situation. 
     Each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may be implemented as various types of devices capable of wireless communication. 
     According to an embodiment, each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may be implemented as a portable wearable device in a form worn by a user. 
     Each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may collect sensing data from sensors included in each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3 . 
     According to an embodiment, each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may collect location data, motion sensing data, or sensing data regarding whether a user wears the wireless communication terminal. 
     According to an embodiment, each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may directly collect location data of each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  using various methods (e.g., Received Signal Strength (RSS), Time of Flight (TOF), angle of arrival, indoor geomagnetic field distribution pattern, etc.). 
     According to another embodiment, each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may transmit a communication signal (e.g., a Bluetooth signal) to the gateway  200 - 1  or  200 - 2  located within a communication range (e.g., RG 1  or RG 2 ). Location data of each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may be collected through the location of at least one gateway ( 200 - 1  or  200 - 2 ) that has received the communication signal (e.g., the Bluetooth signal) transmitted from each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3 . In this case, the location data may refer to the communication signal (e.g., the Bluetooth signal) transmitted from each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3 . 
     According to an embodiment, each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may include a sensor for collecting motion sensing data (e.g., accelerometer, gyro sensor, etc.). 
     According to another embodiment, each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may include a sensor capable of sensing a state of contact with an owner of each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3 .

The identification information of each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  may be stored in advance in a memory (not shown) in the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3 . 
     According to an embodiment, identification information of a wireless communication terminal may refer to various pieces of information for identifying the wireless communication terminal, for example, a media access control (MAC) address, international mobile equipment identity (IMEI), and the like. 
       FIG.  2    is a block diagram of the gateway shown in  FIG.  1   , according to an embodiment.  FIGS.  3  and  4    are conceptual diagrams illustrating a method of setting control that varies depending on the location of a wireless communication terminal in the control system of  FIG.  1   . 
       FIG.  2    shows only the first gateway  200 - 1  from among the gateways  200 - 1  and  200 - 2  shown in  FIG.  1   , but the second gateway  200 - 2  may have a structure substantially the same as that of the first gateway  200 - 1 , and may operate in substantially the same manner as that of the first gateway  200 - 1 . 
     Referring to  FIGS.  1  and  2   , the first gateway  200 - 1  may include a communication interface  210 , a memory  220 , and a processor  230 . 
     The communication interface  210  may interface communication between the server  100  and the first gateway  200 - 1 , communication between the second gateway  200 - 2  and the first gateway  200 - 1 , and communication between wireless communication terminals (e.g.,  300 - 1  and  300 - 2 ) and the first gateway  200 - 1 , and may process data or signals transmitted and received during the interfacing process. 
     The memory  220  may temporarily or permanently store data required to process the processor  230 , data generated during or after the processing of the processor  230 , or the like. 
     The processor  230  may include an abnormal situation determiner  232 , a settable area determiner  234 , and a setting controller  236 . 
     Each of the abnormal situation determiner  232 , the settable area determiner  234 , and the setting controller  236  may mean program code and a logical unit or set of hardware resources capable of executing the program code, and does not necessarily mean physically connected code or a single type of hardware. 
     The abnormal situation determiner  232 , the settable area determiner  234 , and the setting controller  236  may be functionally and logically separated from each other, and this does not necessarily mean that the components are divided into separate physical devices or written in separate codes. 
     The abnormal situation determiner  232  may determine whether an abnormal situation occurs based on sensing data related to the wireless communication terminals  300 - 1  to  300 - 3 . 
     According to an embodiment, the sensing data related to the wireless communication terminals  300 - 1  to  300 - 3  may be sensing data directly collected by the wireless communication terminals  300 - 1  to  300 - 3  or sensing data collected from an external device (e.g., the image collecting device  210 - 1  or the sound collecting device  220 - 1 ) communicatively connected to the first gateway  200 - 1 . 
     According to an embodiment, the abnormal situation may broadly mean a case where there is a problem in the operation of the wireless communication terminals  300 - 1  to  300 - 3 , causing an obstacle in additional authentication using the wireless communication terminals  300 - 1  to  300 - 3 , or the wireless communication terminals  300 - 1  to  300 - 3  may be possessed and abused by someone other than an initial owner. 
     According to an embodiment, the abnormal situation may correspond to a case in which authentication authority granted to an owner of the wireless communication terminals  300 - 1  to  300 - 3  in an initial authentication process has expired, or the wireless communication terminals  300 - 1  to  300 - 3  are out of the scope of the granted authentication authority. 
     According to an embodiment, the abnormal situation may be determined based on at least one of location data and sensing data (e.g., motion sensing data) received from the wireless communication terminals  300 - 1  to  300 - 3 . For example, when the wireless communication terminals  300 - 1  to  300 - 3  are located in an abnormal place (or outside the authentication authority) or when abnormal movement (e.g., staying in one place for a long time and there is no movement or abnormally rapid movement occurs) of the wireless communication terminals  300 - 1  to  300 - 3  is detected, it may be determined as an abnormal situation. 
     According to an embodiment, the abnormal situation may be divided into various types such as non-wearing, damage, loss, or theft of the wireless communication terminals  300 - 1  to  300 - 3 . 
     According to an embodiment, the abnormal situation may be determined based on at least one of image data collected by an image collecting device (e.g.,  210 - 1 ) and sound data collected by an sound collecting device (e.g.,  220 - 1 ). 
     The abnormal situation determined by the abnormal situation determiner  232  may be transmitted to the setting controller  236 , and the setting controller  236  may control setting of a wireless communication terminal (e.g.,  300 - 1 ) in which an abnormal situation occurs according to whether an abnormal situation occurs. 
     According to an embodiment, according to the type of abnormal situation transmitted from the abnormal situation determiner  232 , the setting controller  236  may control setting of a wireless communication terminal (e.g.,  300 - 1 ) in which the abnormal situation has occurred differently. 
     The settable area determiner  234  may determine a location of a wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) requiring control of the setting and determine whether the location of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) requiring control of the setting is located in a settable area. 
     Referring to  FIGS.  2  and  3    together, the first communicable area RG 1  of the first gateway  200 - 1  and the second communicable area RG 2  of the second gateway  200 - 2  are shown together. 
     When the first gateway  200 - 1  controls the setting of the second wireless communication terminal  300 - 2 , normal setting control may be possible only when the second wireless communication terminal  300 - 2  is located within the range of the communicable area RG 1  of the first gateway  200 - 1  for a certain period of time. However, the location of the second wireless communication terminal  300 - 2  is continuously changed, and in a situation where setting control is in progress, the second wireless communication terminal  300 - 2  may deviate from the first communicable area RG 1  of the first gateway  200 - 1 . Accordingly, in consideration of the normal walking speed of a person and the time required for controlling setting of a wireless communication terminal (e.g.,  300 - 2 ), even if the wireless communication terminal (e.g.,  300 - 2 ) moves after the setting control is started, an area in which the wireless communication terminal (e.g.,  300 - 2 ) does not deviate from a communicable area (e.g., RG 1 ) until the setting control is completed may be set as a settable area (e.g., RG 1 -S). 
     The settable area (e.g., RG 1 -S) may be set to be less than the communicable area (e.g., RG 1 ). 
     Similarly, a communicable area (e.g., RG 2 -S) may be set for the second communicable area RG 2  of the second gateway  200 - 2 . 
     The settable area determiner  234  may check a location of the wireless communication terminal (e.g.,  300 - 2 ) requiring setting control, and determine whether the location of the wireless communication terminal (e.g.,  300 - 2 ) requiring setting control is located in the settable area (e.g., RG 1 -S). The settable area determiner  234  may transmit a result of the determination to the setting controller  236 , and the setting controller  236  may start setting control when the wireless communication terminal (e.g.,  300 - 2 ) is located within the settable area (e.g., RG 1 -S). 
     Referring to  FIG.  4    together, when the wireless communication terminal (e.g.,  300 - 2 ) is within the communicable area (e.g., RG 1 ) of the gateway (e.g.,  200 - 1 ), but is outside the settable area (e.g., RG 1 -S), the gateway (e.g.,  200 - 1 ) may transmit data (e.g., control target information (signal transmission level, signal transmission period, target sensor, etc.), or set control value, etc.) necessary for controlling setting of the wireless communication terminal (e.g.,  300 - 2 ) to an adjacent gateway (e.g.,  200 - 2 ) based on a movement pattern of the corresponding wireless communication terminal (e.g.,  300 - 2 ). In this case, based on the movement pattern of the wireless communication terminal (e.g.,  300 - 2 ), the gateway (e.g.,  200 - 1 ) may select the adjacent gateway (e.g.,  200 - 2 ) that is expected to fall within the range of the settable area (e.g., RG 2 -S) according to the movement pattern from among a plurality of adjacent gateways and may transmit data necessary for setting control to the selected adjacent gateway (e.g.,  200 - 2 ). 
     Returning to  FIG.  2   , the setting controller  236  may control setting of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) based on identification information of the first gateway  200 - 1 , identification information of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ), and sensing data related to the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ). 
     According to an embodiment, the setting controller  236  may control a signal transmission level or a signal transmission period of a transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ). 
     According to an embodiment, the setting controller  236  may control power setting of at least one sensor included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ). 
     According to an embodiment, identification information of the gateway (e.g.,  200 - 1 ) may include information about an area in which the gateway (e.g.,  200 - 1 ) is installed. For example, the information about the area in which the gateway (e.g.,  200 - 1 ) is installed may be classified according to the security level of the area. In this case, the identification information of the gateway (e.g.,  200 - 1 ) may be directly stored in the memory  220  or may be received by requesting the server  100 . 
     According to an embodiment, the setting controller  236  may set the signal transmission period of the transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) to be relatively short as the security level of the area in which the gateway (e.g.,  200 - 1 ) is installed is relatively high. 
     According to an embodiment, the setting controller  236  may set the signal transmission level of the transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) to be relatively low as the security level of the area in which the gateway (e.g.,  200 - 1 ) is installed is relatively high. 
     According to an embodiment, the setting controller  236  may determine a management level of an owner of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) based on the identification information of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ), and may control the setting of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) according to the determined management level. In this case, the management level of the owner of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) may be directly stored in the memory  220  or may be received by requesting the server  100 . 
     According to an embodiment, the management level of the owner of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) may be the severity of the patient in the hospital facility, or the risk of the prisoner in the correctional facility. 
     According to an embodiment, the setting controller  236  may set the signal transmission period of the transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) to be relatively short as the management level of the owner of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) is relatively high. 
     According to an embodiment, the setting controller  236  may set the signal transmission level of the transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) to be relatively low as the management level of the owner of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) is relatively high. 
     According to an embodiment, the setting controller  236  may control the setting of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) according to the abnormal situation determined by the abnormal situation determiner  232 . When an abnormal situation occurs, the setting controller  236  may set the signal transmission period of the transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) to be relatively short, or set the signal transmission level of the transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) to be relatively low. 
     According to an embodiment, the setting controller  236  may control the setting of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) differently according to the type of abnormal situation determined by the abnormal situation determiner  232 . According to the severity of each type of abnormal situation that has occurred, as the severity is relatively high, the setting controller  236  may set the signal transmission period of the transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) to be relatively short, or set the signal transmission level of the transmitter included in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) to be relatively low. 
     According to an embodiment, the setting controller  236  may control power setting of a sensor of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) according to the type of abnormal situation determined by the abnormal situation determiner  232 . For example, in the case of an abnormal situation in which additional authentication using the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) is obstructed due to a problem such as a lack of battery in the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ), the setting controller  236  may control the setting so that the power of some sensors in the corresponding wireless communication terminal is turned off. 
       FIG.  5    is a flowchart of a method of operating a gateway according to an embodiment. 
     Referring to  FIGS.  1  to  5   , in operation S  510 , the method of operating a gateway according to an embodiment may receive identification information of the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) and sensing data related to the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ). 
     The sensing data related to the wireless communication terminal (e.g.,  300 - 1  to  300 - 3 ) may be collected from sensors included in each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3 , or may be collected from an external device (e.g., the image collecting devices  210 - 1  and  210 - 2 , and the sound collecting devices  220 - 1  and  220 - 2 ) communicatively connected to a gateway (e.g.,  200 - 1  or  200 - 2 ). 
     According to an embodiment, the sensing data may be location data of each of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3 , motion sensing data, or sensing data regarding whether a user wears the wireless communication terminal. 
     In operation S 520 , the method of operating the gateway according to an embodiment may control the setting of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  based on the identification information and sensing data of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  received in operation S 410 , and the identification information of the gateway (e.g.,  200 - 1  or  200 - 2 ) that received the identification information and sensing data of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  received in operation S 410 . 
     According to an embodiment, the setting of the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3  controlled by the gateway (e.g.,  200 - 1  or  200 - 2 ) may be the signal transmission level of the transmitter included in the wireless communication terminals  300 - 1 ,  300 - 2 , and  300 - 3 , the signal transmission period of the transmitter, or the power setting of the sensor. 
     The method of operating a gateway according to an embodiment may be implemented as a program including program code for performing operations S 510  and S 520  and stored in a medium, and a processor may be combined with the medium to execute the program. 
     Methods and apparatuses according to an embodiment may optimize a wireless communication terminal to a control situation by controlling setting of the wireless communication terminal possessed by a user based on identification information of the wireless communication terminal, sensing data related to the wireless communication terminal, and identification information of a gateway.
