An event notification system includes a data communications network (18), at least one event server (20) coupled to the data communications network and at least one subscriber (12) coupled to the data communications network. The subscriber is operable to send a subscribe message to the event server, the subscribe message containing information for specifying at least one application semantic. The event server is operable to generate a first notification to the subscriber upon the at least one application semantic being satisfied and to generate a second notification to the subscriber upon a change in the specified application semantic, thereby enabling an occurrence of a substitution of the specified application semantic with another application semantic.
A method to subscribe to an event server to be notified of an occurrence of an event through a data communications network, comprising:
An event notification system comprising a data communications network, at least one event server coupled to the data communications network, and at least one subscriber coupled to the data communications network, where said subscriber is operable to send a subscribe message to the event server, the subscribe message comprising information for specifying at least one application semantic;
An event server, comprising an interface for coupling to a data communications network and a control logic, responsive to receipt of a subscribe message from a subscriber that comprises information for specifying at least one application semantic, to generate a first notification to the subscriber upon the at least one application semantic being satisfied and to generate a second notification to the subscriber upon a change in the specified application semantic, enabling an occurrence of a substitution of the specified application semantic with another application semantic.
A subscriber unit, comprising an interface for coupling to a data communications network and a control logic for generating a subscribe message that is sent via the data communications network to an event server, the subscribe message comprising information for specifying at least one application semantic, said control logic being responsive to a receipt of a first notification from the event server of the at least one application semantic being satisfied, and being further responsive to a receipt of a second notification from the event server upon a change in the specified application semantic for enabling a substitution of the specified application semantic with another application semantic.
A computer program product embodied on or in a computer-readable data storage medium execution of which directs at least one data processor to subscribe to an event server so as to be notified through a data communications network of an occurrence of an event, comprising operations of:
