METHOD AND SYSTEM FOR PROVIDING CONTENT-BASED ACCESS TO PRESENCE METHOD AND SYSTEM FOR PROVIDING CONTENT-BASED TO PRESENCE INFORMATION

摘要

A method and system for providing content-based access to presence information for an entity are described. The method, which may be implemented in a server, includes maintaining a plurality of state definitions for entities, each state definition including an expression of conditions to be met in data of presence information for an entity. The method further includes receiving presence information for an entity, evaluating in a computer-based application, the presence information for the entity with respect to the state definitions to determine if a state definition evaluates to true against the presence information, and providing results of a state definition. The results may be provided as a subscription to a state definition or in reply to a query request for a state definition.
