<p>A system (300) for processing context data comprising means for receiving context data (304,308,402,404,406) from a plurality of sources (302); means for producing context information (310,312,314,316) from the received context data according to a predetermined rule-set including a plurality of rules; and means for communicating (308,316,400,404,406) the context information to at least one application, wherein the system (300) includes means for permitting at least one protocol-source (302,304,404) to specify instructions and/or rules related to a communication protocol for communication between the protocol-source and the system, thereby updating the means for receiving (304,308,402,404,406) and/or the means for communicating (308,316,400,404,406). The system (300) further includes means for permitting at least one rule-source (302,304,402) to specify at least one rule thereby updating the rule-set, wherein the rule-source (302,304,402) specifies rules for filtering and/or formatting the context data and rules for producing context information from context data. The system (300) is used in a network (Fig. 4) for processing context data. One or more systems (300) are implemented on a wireless apparatus (102).</p> |
