INFORMATION SERVICE AND METHOD

摘要

A server-based event-driven information notification system for a palmtop computer. A push server is programmed to provide selected information to a palmtop computer. The push server periodically queries the Internet or a service provider in order to cache information selected by a palmtop user. The push server attempts to push the information instantaneously to the palmtop computer. If the palmtop computer is off-line, the push server will fail to receive an acknowledgement of the pushed information and the information is stored. When the palmtop user goes on-line, the selected information is pushed to the palmtop computer. This provides the advantage of allowing the user of the palmtop computer to obtain up to the minute information which is pushed to the palmtop computer whenever it is on-line.
