A method and apparatus for obtaining context information from a context server maintaining a context for an object of interest in a telecommunication network. The context server receives raw context data from sensors associated with the object of interest. A request is received from a requesting party for refined context information with reference to the object of interest. Individual context data is collected for at least one individual entity of the requesting party. A customized rule is created on the basis of the received individual context data. The rule defines conditions in an adapted request for refined context information regarding the object of interest, which is sent, including the customized rule, to the context server of the object of interest. Context data refined according to the customized rule is then received from the context server.
