       FIG. 6  is a block diagram for describing a second electronic device which is in charge of each section by dividing tables in a store into a plurality of sections according to an embodiment of the present disclosure. 
     First, as illustrated in  FIG. 6 , the table group section includes a plurality of sections in which the plurality of tables located in the store are divided into a single section having the number of tables set based on positions of the tables and the number of seats. Specifically, the sections are divided into a single section having the number of tables set based on the total number of seats of the tables located in the store, the position of each table, the number of staff working in the store, an operating time and the day of week and the like. 
     For example, a case, in which the total number of tables in a rectangular-shaped store is 28, wherein first to fourth tables capable of seating five customers are arranged in each of four corners, and a fifth table capable of seating eight customers is arranged in a center, will be described below. 
     First, in the above-described example, in weekday morning hours having a relatively small number of customers, the first and second tables may be set as a first section which is a single section, the third and fourth tables may be set as a second section which is another section, and the fifth table may be set as a third section which is the last section. 
     On the other hand, in the above-described example, in weekday evenings or weekends having a relatively large number of customers, the first to fifth tables may be set as the first to fifth sections, respectively. 
     In addition, the table sections may be set to be further subdivided when there are many staff working in the store, while setting of the table sections may be set not to be subdivided, when there are few staff working in the store. 
     For example, the setting of the table section may be a concept which can be changed based on the total number of seats of the tables located in the store, the position of each table, the number of staff working in the store, an operating time and the day of week and the like. 
     Also, the second electronic device may be a variety of electronic devices carried by at least one staff in charge of the table group section in which the first electronic device is located. For example, the staff in the store may provide the services to the customers with the second electronic device worn on a wrist in a form of a wearable device, respectively. 
     In an embodiment of the present disclosure, the plurality of tables in the store are grouped in a single section, respectively, as well as the second electronic devices carried by staff in the store are also grouped so that the staff are in charge of each section. 
     For example, as illustrated in  FIG. 6 , a case, in which the number of tables in the store is five, wherein a first table  611  and a second table  612  are set as a first section  610 , and third to fifth tables  621 ,  622  and  623  are set as a second section  620 , as well as a total of seven staff are in the store, and each staff provides the service to the customers with an electronic device worn on a wrist in a form of the wearable device, will be described below. 
     In the example described above, three second electronic devices  613  may be grouped to be in charge of the service of the customers in the first section  610 , and four third electronic devices  624  may be grouped to be in charge of the service of the customers in the second section  620 . 
     As described above, in the embodiment of the present disclosure, since the plurality of tables in the store are grouped in a single section, respectively, as well as the second electronic devices carried by staff in the store are also grouped so that the staff are in charge of each section, there is an advantage of being capable of providing the customers the customized service. 
       FIGS. 7A and 7B  are views for describing a group management method according to embodiments of the present disclosure. First,  FIG. 7A  is a view for describing contents of managing the group in a method of moving a table list according to an embodiment of the present disclosure. 
     In a manager electronic device, the tables in the store may be grouped into a single section, respectively, and the number of staff and the staff in charge of each group may be specified. 
     For example, as illustrated in  FIG. 7A , the manager electronic device may receive a command to perform a group modification from a manager, and may display a table window capable of performing the setting of sections for the tables in the store and a modification thereof, and a receiver window capable of performing the setting of staff in charge of each group and the modification thereof. 
     For example, the manager electronic device may receive a designation of the section and the table from the manager, and then may receive a selection of a shift key  710  to perform the setting of sections for the tables in the store and a modification thereof. 
     In addition, the manager electronic device may receive a designation of the staff from the manager, and then may receive the selection of a shift key  720  to perform the setting of staff in charge of a specific group and the modification thereof. 
     Thereafter, the manager electronic device may receive an input of a storage key  730  or a cancel key  740  according to the selection of the manager, and may store or cancel the input and modified contents, respectively. 
       FIG. 7B  is a view for describing contents of managing the groups in a drag and drop method according to an embodiment of the present disclosure. In a manager electronic device, the tables in the store may be grouped into a single section, respectively, and the number of staff and the staff in charge of each group may be specified. 
     For example, as illustrated in  FIG. 7B , the manager electronic device may receive a command to perform a group modification from a manager, and may display an entire electronic device  750  carried by an entire staff in the store and respective sections  760 ,  770 ,  780  and  790  in a user interface (UI) manner. 
     Thereafter, the manager electronic device may receive selection of one of the electronic devices  750  according to the selection of the manager, and drop the selected electronic device in a section region to be designated in the dragged state, then the selected electronic device may be grouped into the designated section. 
     According to some exemplary embodiments of the present disclosure, the manager may easily set and modify the section and the staff by using the shift key, or the drag and drop method, thus there may be an advantage of improving the convenience of the user. 
       FIGS. 8A and 8B  are flowcharts for describing methods for transmitting and processing a group message in a store using a system, when a operation server is a socket server according to embodiments of the present disclosure. First, as illustrated in  FIGS. 8A and 8B , the second electronic device performs a connection step ( 811 ) with the socket server.

Then, when the verification is completed, pairing between the second electronic device and the socket server may be completed to connect with each other. 
     Thereafter, at the step ( 812 ), the first electronic device may receive an input of a service request from the customer. For example, the first electronic device may receive an input of a service request from the customers, such as service requests, inquiries, calls and orders. At this time, the first electronic device may include a call bell and an electronic menu, which are placed on the table, and a customer&#39;s own electronic device. 
     At the step ( 813 ), the first electronic device may transmit a service request signal to the AP. For example, the first electronic device may convert the service request received from the customer who uses the table into a service request signal corresponding to the service request, and may transmit the converted service request signal to the AP. 
     At the step ( 814 ), the AP may transmit the table group section information, the table number information and the service request signal of the table in which the first electronic device is located to the message server. For example, a specific frame of the service request signal received from the first electronic device by the AP may include the table group section information and the table number information of the table in which the first electronic device is located. Thereby, the AP may transmit the table group section information, the table number information and the service request signal to the message server. 
     At the step ( 815 ), the message server may detect the serial number information or login information of the second electronic device and may analyze the service request signal to generate a service message. For instance, the message server may detect the serial number information or login information of the second electronic device in order to identify the electronic device of the staff in charge of the section to which the table of the customer who has input the service request belongs. 
     At the step ( 816 ), the message server may transmit the serial number information or login information of the second electronic device, the table number information and the service request signal of the table in which the first electronic device is located to the socket server. For instance, the message server may request the socket server to transmit the serial number information or login information of the second electronic device carried by at least one staff in charge of the table group section in which the first electronic device is located, the table number information and the service request signal of the table in which the first electronic device is located to the socket server, and simultaneously transmit the service message to the second electronic device. 
     If it is determined to be a preset urgent message as a result of analyzing the service request signal by the message server, the message server may request the socket server to transmit the table number information of the table in which the first electronic device is located, and simultaneously transmit the urgent message to the electronic devices carried by all the staff in the store in a group. 
     According to an embodiment of the present disclosure, when the service request of the customer is urgent, the message server may transmit the urgent message to the electronic devices of all staff in the store, such that there is an advantage that the safety of the customer may be improved and negligence may be prevented. 
     In the message server, if it is determined that there is one second electronic device carried by at least one staff in charge of the table group section in which the first electronic device is located, the message server may detect the serial number information or login information of the one second electronic device, and serial number information or login information of at least one third electronic device which is in charge of the preset section among the remaining sections other than the table group section in which the first electronic device is located. Then, the message server may transmit the serial number information or login information of the detected one second electronic device, the serial number information or login information of the third electronic device, and the table number information and the service message of the table in which the first electronic device is located to the socket server. 
     The reason is that, if it is determined that the service message has failed to be transmitted in the socket server later on as a result of transmitting the service message to the one second electronic device, the message server may transmit the table number information and the service message of the table in which the first electronic device is located to the manager electronic device and the third electronic device in charge of other sections. 
     According to an embodiment of the present disclosure, when there is only one staff in charge of one section, it may prepare for a case in which the service message cannot be transmitted due to a network problem, a power problem, and a staff who does not wear the electronic device, thereby achieving an advantage of improving the safety. 
     At the step ( 817 ), the socket server generates a service message. For example, the socket server may receive a request from the message server to transmit the service message to the second electronic device, and may generate a service message. 
     At the step ( 818 ), the socket server may transmit the table number information and the service message of the table in which the first electronic device is located to the second electronic device. At this time, the socket server may transmit the service messages to all the second electronic devices in charge of the section to which the first electronic device belongs, or may transmit the service message to any one of the second electronic devices. 
     For example, when the customer is a customer who needs for the staff to pay them particular attention, such as a VIP, elderly and the infirm, children, pregnant women, and disabled persons, the socket server may transmit the service message to all the second electronic devices in charge of the section to which the first electronic device belongs. 
     When the socket server receives a request to transmit an urgent message to all the electronic devices carried by the staff in a group from the message server, the socket server may transmit the urgent message to all the electronic devices carried by all the staff in a group. 
     On the other hand, when the socket server receives the serial number information or login information of the second electronic device that has performed first another service request from another customer among the second electronic devices from the message server, the socket server may transmit the table number information and the service message of the table in which the first electronic device is located only to the second electronic device that has performed first another service request from another customer. 
     According to an embodiment of the present disclosure, when the customer is a customer who needs to be paid particular attention, there is an advantage that the service message may be transmitted in a group to the electronic devices of all the staff in charge of the section, thereby providing a more particular service. 
     In addition, according to an embodiment of the present disclosure, since a service response time of the staff is considered by allowing a staff who has responded first to the customer among the staff who are in charge of one section to perform a new service request, there may be an advantage that the customer may receive the best service, and the staff may respond to the customer in an unhurried manner. 
     At the step ( 819 ), the socket server transmits a processing result to the message server, and then at the step ( 820 ) the message server receives the processing result from the socket server to transmit it to the AP. 
     At the step ( 821 ), the second electronic device may notify the staff, which is a user, of a reception of the service message, and then receives selection of the notification. 
     At the step ( 822 ), when at the step ( 822 ) the second electronic device may request a call list to the message server according to the selection of the staff who is the user, at the step ( 823 ) the message server may transmit the call list to the second electronic device. Herein, the call list may refer to, for example, but not limited to, a list in which various service requests received from the customers are recorded. 
     At the step ( 824 ), the second electronic device may receive selection of an accept button according to the selection of the staff who is the user. For instance, the second electronic device may receive the call list transmitted from the message server, and may receive selection of an accept button after displaying the call list. 
     Then, when at the step ( 825 ) the second electronic device transmits the processing result to the message server, at the step ( 826 ) the message server may process the request. 
     Thereafter, the second electronic device may recognize the service message at the step ( 827 ), and may transmit the processing result to the first electronic device at the step ( 828 ), then the first electronic device may transmit a beacon signal to the second electronic device at the step ( 829 ). 
     Thereafter, the second electronic device may complete the recognition at the step ( 830 ) and may transmit the recognition result to the message server at the step ( 831 ), then the message server may process the request at the step ( 832 ), and may transmit the processing result to the second electronic device at the step ( 833 ). 
       FIGS. 9A and 9B  are flowcharts for describing methods for transmitting and processing a group message in a store using a system, when an operation server is a message push server according to embodiments of the present disclosure. First, as illustrated in  FIGS. 9A and 9B , at the step ( 911 ), the first electronic device may receive an input of a service request from a customer. For example, the first electronic device may receive an input of a service request from customers, such as detailed service requests, inquiries, calls and orders. For instance, the first electronic device may include the call bell and the electronic menu, which are placed on the table, and the customer&#39;s own electronic device. 
     Thereafter, at the step ( 912 ), the first electronic device may transmit a service request signal to the AP. For example, the first electronic device may convert the service request received from the customer who uses the table into a service request signal corresponding to the service request, and may transmit the converted service request signal to the AP. 
     Then, at the step ( 913 ), the AP may transmit the table group section information, the table number information, and the service request signal to the message server. For instance, a specific frame of the service request signal received from the first electronic device by the AP may include the table group section information, and the table number information of the table in which the first electronic device is located. The AP may transmit the table group section information, the table number information, and the service request signal to the message server. 
     Thereafter, at the step ( 914 ), the message server may detect the serial number information or login information of the second electronic device, may analyze the service request signal, and may generate a service message. For example, the message server may detect the serial number information or login information of the second electronic device in order to identify the electronic device of the staff in charge of the section to which the table of the customer who input the service request belongs. 
     Thereafter, at the step ( 915 ), the message server may transmit the serial number information or login information of the second electronic device, the table number information and the service message of the table in which the first electronic device is located to the message push server. For example, the message server may request the message push server to transmit the serial number information or login information of the second electronic device carried by at least one staff in charge of the table group section in which the first electronic device is located, the table number information and the service message of the table in which the first electronic device is located, and may simultaneously push the service message to the second electronic device. 
     If it is determined to be a preset urgent message as a result of analyzing the service request signal by the message server, the message server may request the message push server to transmit the table number information of the table in which the first electronic device is located, and simultaneously transmit the urgent message to the electronic devices carried by all the staff in the store in a group. 
     If it is determined that there is one second electronic device carried by at least one staff in charge of the table group section in which the first electronic device is located, the message server may detect the serial number information or login information of the one second electronic device, and serial number information or login information of at least one third electronic device which is in charge of the preset section among the remaining sections other than the table group section in which the first electronic device is located. Then, the message server may transmit the serial number information or login information of the detected one second electronic device, the serial number information or login information of the third electronic device, and the table number information and the service message of the table in which the first electronic device is located to the message push server. 
     The reason is that, if it is determined that the service message has failed to be transmitted in the message push server later on as a result of transmitting the service message to the one second electronic device, the message server may transmit the table number information and the service message of the table in which the first electronic device is located to the manager electronic device and the third electronic device in charge of other sections. 
     Then, at the step ( 916 ), a message push server may push the table number information and the service message of the table in which the first electronic device is located to the second electronic device. At this step, the message push server may transmit the service messages to all the second electronic devices in charge of the section to which the first electronic device belongs, or may transmit the service message to any one of the second electronic devices. 
     For example, when a customer needs for the staff to pay them particular attention, such as a VIP, elderly and the infirm, children, pregnant women, and disabled persons, the message push server may transmit the service message to all the second electronic devices in charge of the section to which the first electronic device belongs. 
     When the message push server receives a request to transmit an urgent message to all the electronic devices carried by the staff in a group from the message server, the message push server may transmit the urgent message to all the electronic devices carried by all the staff in a group. 
     On the other hand, when the message push server receives the serial number information or login information of the second electronic device that has performed first another service request from another customer among the second electronic devices from the message server, the message push server may transmit the table number information and the service message of the table in which the first electronic device is located only to the second electronic device that has performed first another service request from another customer. 
     Thereafter, at the step ( 917 ), the message push server may transmit a processing result to the message server, and then at the step ( 918 ) the message server may receive the processing result from the message push server to transmit it to the AP. 
     Substantially, at the step ( 920 ), the second electronic device may notify the staff, which is a user, of a reception of the service message, and then may receive a selection of the notification. 
     Thereafter, when the second electronic device requests a call list to the message server according to the selection of the staff who is the user at the step ( 921 ), the message server may transmit the call list to the second electronic device at the step ( 922 ). 
     Thereafter, at the step ( 923 ), the second electronic device may receive a selection of an accept button according to the selection of the staff who is the user. For instance, the second electronic device may receive the call list transmitted from the message server, and may receive a selection of an accept button after displaying the call list. 
     Then, when the second electronic device transmits the processing result to the message server at the step ( 924 ), the message server may process the request at the step ( 925 ). 
     Thereafter, the second electronic device may recognize the service message at the step ( 926 ), and may transmit the processing result to the first electronic device at the step ( 927 ), then the first electronic device may transmit a beacon signal to the second electronic device at the step ( 928 ). 
     Thereafter, the second electronic device may complete the recognition at the step ( 929 ), and may transmit the recognition result to the message server at the step ( 930 ), then the message server may process the request at the step ( 931 ), and may transmit the processing result to the second electronic device at the step ( 932 ).
