An event-processing method and system are provided for efficiently re-delivering notification events stored by a Remote User Interface Server (RUIS), from the RUIS to remote user interface clients (RUICs), in a home network supporting an RUI. An RUIC transmits an information request to the remote user interface server, receives, from the RUIS, notification event information corresponding to the information request, transmits a notification event request based on the received notification event information to the RUIS, and receives, from the RUIS, at least one notification event corresponding to the notification event request.
