Abstract
A system for remote control of a mobile computer system from a base computer system, where the base system generates control command tokens which are broadcast over a pager system. A communicator including a pager receiver, which is normally in a standby state, is connected to the mobile computer, which is normally in an off state, and receives the command tokens. Stored in both the base computer and the mobile computer is a table of commands, cross-referenced with the command tokens. The command tokens are used to instruct the mobile computer to take a variety of actions, including telephoning the base computer, informing the base computer of the mobile computer's location, exchanging file update information and application version information, and other actions requiring communication between the base station and the remote station. The communicator includes a local CPU and SRAM, and powers up the mobile computer as necessary. Certain commands and information exchange may be carried out by the local CPU without powering up the mobile computer.
