SERVER AND METHOD MANAGING LOCATIONS OF MULTIPLE COMMUNICATION TERMINALS

PROBLEM TO BE SOLVED: To reduce a load of a server and accurately grasp locations of communication terminals.SOLUTION: A server receives a terminal ID and terminal information from each communication terminal and manages the received terminal information corresponding to the received terminal ID as terminal management information. The terminal information is information related to the communication terminal which has transmitted the terminal information and includes location information which is information indicating a location of the communication terminal. The server specifies a communication terminal which exists in a specified area among a plurality of communication terminals on the basis of the terminal management information, and executes control so that a frequency to receive the terminal information from the terminal within the specified area which is the specified communication terminal becomes higher than a frequency to receive the terminal information from terminals outside the specified area which are communication terminals existing outside the specified area.
