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.

Systems and methods are disclosed for tagging and translating database objects and relationships into sentences. The successive composition of these sentences form hierarchies which encode contextual information about the objects. A virtual directory / context server functions using a common abstraction layer to access data from databases, applications, directories, Web Services, and other data sources within the enterprise. The virtual directory / context server includes a sentence / context builder module that enables the translation or relationships between data and from the plurality of data sources into a human-readable form, for example, an English language sentence. Thus, applications can view, access, and / or modify the data from the data sources of the enterprise through the virtual directory / context server, for example, using the sentences representative of the relationships between the data. The sentences are indexed, which allows for searches that bring information not only about objects, but also about the context in which those objects appear.

Providing a context-based service to a terminal, including: a) receiving a query from a service application, the query indicating that a context server should perform an action when a query condition is fulfilled, the query condition referring to one or more attributes of derived context information indicative of a context of the terminal; b) generating a query evaluation trigger indicating that the query condition should be evaluated; c) identifying raw context information to derive the derived context information; d) generating a calculation trigger indicating that the derived context information should be calculated when the raw context information is updated; e) receiving an update of the raw context information and, according to the calculation trigger, calculating a new value of the derived context information; and f) according to the query evaluation trigger, evaluating the query condition by using the new value and, if the query condition is fulfilled, performing the action.

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.

A system and method provides content to a mobile device in response to a marker received from the device and an associated context. A mobile device user initiates delivery of content or another action by entering the marker into the mobile device. The mobile device transmits the marker to a mobile network support system having a context server for supplying a context for the marker. The support system forms a message including the marker and context, and sends it to a content server. The content server uses the context to map the marker to a domain, retrieves from a content database the content identified by the marker and domain, and sends the content to the mobile network support system or performs another action with the content. The mobile network support system then transmits the content back to the mobile device.
