At this time, if a new mobile device requests registration in the area 920, the central web server 910 sends the group 930 to two sub-services (not shown) so that the number of subscribers in the group 930 does not exceed the predetermined maximum number of subscribers. Group 930 and 940, respectively. After finishing the division, the central web server 910 selects the leader terminals 931 and 941 among the subscribers of the respective subgroups, and notifies each of the leader terminals 931 and 941 of the group management.

According to one embodiment, the central web server 910 may send a group leader and a group leader terminal using a reader terminal selection algorithm based on a subscriber's message sending capability or other criteria (signal strength, battery level, number of cell towers, etc.) Select. The central web server 910 transmits the message to all subscribers by using the leader terminal of the group and subgroup as a relay node.

10 is a view for explaining a method of managing a group by the leader terminal 1011 of the group and the leader terminals 1021 and 1031 of the subgroup.

According to one embodiment, the leader terminal 1011 of the group and the leader terminals 1021 and 1031 of the subgroup receive information on group management and message distribution from the central web server to maintain the group related information. The database relating to group management includes information indicating the phone number of all the mobile devices belonging to each group, information indicating whether the terminal is a member terminal (a terminal other than a leader terminal) and a leader terminal, and when the mobile terminal is a leader terminal, Can also be stored. The leader terminal of the group and the subgroup continuously updates the database associated with the group through the control message of the central server.

The member terminals 1012, 1013, 1014, 1015, 1022, 1023, 1032, and 1033 can confirm whether the leader terminal connected to the member terminals 1012, 1013, 1014, 1032, and 1033 is in the active state through the confirmation message. If the mobile device fails to receive a message for a predetermined period of time or a predetermined period of time, the mobile device may check the activation status of the reader terminal associated with the mobile device via the confirmation message and send an error message directly to the central web server . When the central web server receives an error message more than a predetermined number of times to mobile devices in the same group, the central web server can confirm application installation, operation of mobile communication network, etc., A new leader terminal can be selected.
