Abstract:
1. A method for searching for one or more mobile devices having location information in a searchable range within an arbitrary geographical boundary, the method comprising: generating a referential index pair in relation to one or more location points of the one or more mobile devices, wherein generating further includes generating a one-dimensional spatial index and generating a temporal index, where generating a temporal index is performed using a location report processor which determines a location-by-time index value in relation to location information of the one or more mobile devices, wherein the location report processor executes: receiving a location report having location information of the one or more devices; calculating a z-value from a latitude and longitude of the received location information for at least one of the one or more mobile devices; and calculating a time slot from a location timestamp associated with at least one of the one or more mobile devices.
