Abstract
Provided is a distributed system and method for enabling new and useful location dependent features and functionality to mobile data processing systems. Mobile data processing systems interact with each other as peers in communications and interoperability. Indirectly located mobile data processing systems are located relative other mobile data processing systems, and are automatically located using whereabouts data of directly located mobile data processing systems and/or whereabouts data of other indirectly located mobile data processing systems. A mobile data processing system may dynamically take on roles of being directly located or indirectly located, depending on the environment and capabilities available at a particular time. Reference whereabouts data is appropriately shared between mobile data processing systems to carry out automatic location techniques ensuring mobile data processing systems are kept up to date with their own whereabouts and whereabouts of others, regardless of the freely moving travels of any of the mobile data processing systems involved, and the location technologies that may or may not be available when needed. A confidence is associated to whereabouts data shared for facilitating selection of the best candidate data used in determining new whereabouts information.
