Abstract: A moving object data system having an index managing function for improving access speed to moving object data and a method for managing the index are provided to dynamically support insertion/search/deletion of a moving object by using the present index. A query processing component(200) inserts location information of the moving object by a location report of the moving object or processes a search/deletion request for the stored location information of the moving object. A data managing component(300) stores/manages the location information of the inserted moving object. An index managing component(400) includes more than one index component(500) differently applied to each moving object, and manages each index component according to the insertion/search/deletion request for the location information of the moving object. A disk managing component(600) stores the location information and the index information of the moving object. A screen outputting component(100) outputs location of the moving object or the information included by the searched object to a screen.

Abstract: PURPOSE: A location obtaining system of a moving object for minimizing a communication load is provided to reduce a frequency of obtaining future moving object location information by using past location information of a moving object in an LBS(Location Based Service), thereby minimizing a communication load. CONSTITUTION: A moving object location obtaining time checker(202) stores moving objects in a standby queue to maintain a standby state, checks time of each moving object by going round a loop, and removes a moving object whose obtaining time elapses from the standby queue. A location obtaining framework portion(204) receives information on the removed moving object to store the information in the standby queue, and assigns the information to an empty thread within a thread pool for obtaining location information of the multiple moving objects. A location obtaining device portion(206) accesses to various location obtaining sources, and obtains substantial location information. A location obtaining model portion(208) resets location obtaining time of the obtained moving object, and calculates the time by applying various location obtaining processes.
