Abstract: A system for transmitting, to a mobile device, responsive to presence-based filtering, a notification of data received by at least one information repository identified by a user of the mobile device includes at least one notification agent, a presence agent, a notification service, and a communications agent. The at least one notification agent monitors at least one information repository identified by a user and receiving an identification of a modification to the at least one information repository. The presence agent provides presence-related data associated with the user. The notification service, in communication with the at least one notification agent and with the presence agent, applies a filter to the presence-related data and generates a message including the identification of the modification, responsive to the application of the filter to the received presence-related data. The communications agent transmits the generated message to a mobile device associated with the user.

Abstract: A system for transmitting, to a mobile device, a notification of newly-received personal information manager data associated with a user of the mobile device, responsive to presence-based filtering, includes a notification agent, a presence agent, a notification service, and a communications agent. The notification agent receives an identification of data received for a user of a personal information manager. The presence agent provides presence-related data associated with the user. The notification service, in communication with the notification agent and with the presence agent, applies a filter to presence-related data and generates a message including the identification of the received data, responsive to the application of the filter to the received presence-related data. The communications agent transmits the generated message to a mobile device associated with the user.

Abstract: A system for transmitting, to a mobile device, a consolidated notification of updated personal information manager data associated with a user of the mobile device includes a notification agent, a notification service and a communications agent. The notification agent receives a first identification of received event data associated with a user of a personal information manager. The notification service receives the first identification of received event data, delays transmission to the user of the first notification of the identification of received event data, receives a second identification of received event data, determines that the second identification of received event data and the first identification of received event data relate to a single event, and selects one of the second identification of received event data and the first identification of received event data after the predetermined period of time elapses.
