Personal mobile communication system

摘要

With the advent of personal digital assistants (PDAs) having modems for information, e.g., facsimile and/or data, transmission over wireless connections, as well as the capability for voice communications, we have recognized that is possible to communicate with a person, wherever they are, in whatever form is desired. In order to do so in a manner that simulates the way a person at a fixed location having a separate telephone, fax machine and data modem would communicate, incorporate into a PDA is a) a receiver for a wireless actuation signal that indicates that a communication of some type is waiting for a called party; b) an outgoing connection origination unit that establishes a connection from the PDA to the waiting communication; c) a discriminator, which makes a determination as to the type of communication that is waiting; and d) a selection unit that routes the information signals received over the connection established by the PDA to an appropriate communication unit within the PDA, e.g., a fax modem, data modem, or voice communication unit, the appropriate communication unit being selected in response to the type of communication that was determined by the discriminator to be waiting. The PDA owner may optionally be alerted only when 1) an information transmission is successfully completed and the received information is waiting in the PDA for access by its owner, or 2) when a voice connection has successfully been established to the communication originator who continues to indicate a readiness to communicate.
