A communications system including one or more alert gates and an alert controller. Each alert gate is configured to detect a different type of alert feed corresponding to a particular kind of alert. The alert controller is connected to the alert gates and operable to receive detected alerts from the alert gates and to deliver the detected alerts to a user of the communications system.

An event notification matching system, including an event matching table forming a plurality of nodes. Each node is assigned a subscriber request value and contains identifiers for one or more subscribers to be notified at the occurrence of an event relating to the subscriber request value. The event notification matching system may also include a table index. The table index receives input values from an event processing module and selects one or more of the nodes that have subscriber request values corresponding to the received input values. The event processor receives event data from a predetermined source, and formats the input values to simplify the operations performed by the event matching table. The event notification matching system is configured such that the event data need not be compared to non-matching nodes in the event matching table.

Providing an electronic notification to an intended recipient includes communicating an electronic notification directed to an intended recipient, determining a lifespan related to a duration of relevance of the electronic notification, and providing the electronic notification to the intended recipient when the lifespan has not expired. The duration of relevance describes a time period during which information of the electronic notification reasonably may be expected usefully to inform an action or interest of the intended recipient. After the lifespan expires, provision of the electronic notification to the intended recipient may be prevented.

Delivery of an electronic communication using a lifespan

Delivering an electronic notification to an intended recipient may include communicating an electronic notification directed to an intended recipient, and determining presence information associated with the intended recipient before attempting to deliver the notification to the intended recipient. A cascaded delivery instruction also may be resolved based on notification information. The presence information and the cascaded delivery instruction may be used to select among several delivery mechanisms potentially available for the intended recipient based on the presence information, and to deliver the electronic notification to the intended recipient at the selected delivery mechanism. The presence information may include an online presence and/or a physical presence of the intended recipient.
