Management system for handling geographical location data from localizable objects, e.g. mobile phones, and answering user requests for location data, so that direct location requests and consequently network loading are reduced

摘要

System comprises a location memory (18) containing location and time data from the localizable objects; calculation means (16) for determining the quality of position data based on the current time and stored time-date positional data; and comparison means (16) for determining if the quality of stored position data is sufficient for the interrogating object or application. If not, a localization source or server (3) is interrogated directly.
