A flexible and extensible context server for collecting, maintaining, and disseminating context information is disclosed. The context server receives requests from requesters for context information via a secure context server interface (SCS API). Communication between the requesters and the context server is conducted by means of predetermined forms. The requests received at the SCS API are passed to a mediator, which collects data from various context drivers. Each context driver is coupled to the mediator, and collects predetermined type of context information from at least one context information source. The mediator determines the appropriate context driver which can handle the request, based on its type. Operation of the context server is also controlled by a set of context utilities, including a context cache for storing recently obtained context information, a privacy engine for storing privacy preferences and an event engine for event handling.

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.

A source device includes various sensors, such as a GPS receiver. The source device provides operation context data to a server that indicates movement of the source device. The source device may also provide a movement context. The server also evaluates usage of data from the device by other applications or devices to determine a usage context. Based on the movement, operation, and usage contexts, the server selects a frequency at which data is collected for a sensor and a frequency at which the data is transmitted to the server. For example, where the device is not moving or is indoors, less location data is collected. Where no user is tracking the device, location data may be transmitted less frequently and may also be collected less frequently.
