Abstract
A method for remotely updating software code of personal handy phone system equipment. The present invention enables a remotely located control terminal to update stored software code within a distant portable station or cell station of the personal handy phone system. Specifically, by coupling a control terminal to the existing communication network of a personal handy phone system, the control terminal is able to communicate with portable stations and cell stations. To update the software code of a specific portable station or cell station, the control terminal first establishes communication with that particular device by sending an unique preparatory signal addressed to it. The addressed device receives the unique preparatory signal and checks the validity of it. If the addressed device determines the unique preparatory signal is valid, it transmits a unique verification signal addressed to the control terminal indicating that it is ready to receive the updated version of the software code. Once the control terminal receives the unique verification signal from the particular portable station or cell station, it proceeds to download an updated version of software code into the f…
