ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention generally relates to the field of telecommunications and more particularly, is directed to a mobile telecomputing device which can automatically receive, transmit and relay telecommunications information and data.
SUMMARY OF THE INVENTION
The telecommunications system for the present invention makes it possible to cause the automatic unattended receipt of E-MAIL, facsimile, telex, telegrams, voice mail and two-way voice communications. The system includes a telecomputer device which is portable and operates from battery power or from an A/C power line when one is available.
The telecomputer has an electronic microprocessor circuit board that directly interfaces a numeric or alphanumeric paging radio receiver system having a port for downloading data and which is removable or non-removable from a portable computer that also internally contains a cellular telephone.
Specially coded control signals relayed through the pager by way of the interface microprocessor circuit board may be used to activate or turn on the electrically dormant or unpowered standby computer, data modem, facsimile modem, wireline modem, and cellular telephone transceiver sections of the telecomputer, thereby making it possible through special function control programming to cause the cellular telephone to automatically dial a local or (800) national or international telephone number. This number's phone system is connected to a data distribution center that upon receiving the pager induced looped call from the portable telecomputer's internal cellular transceiver, automatically transfers back to the portable machine's computer data storage section, an electronic data message such as E-MAIL, file archives, group level-3 facsimiles, telefax, telegram or when attended, voice mail or two-way voice calls.
The information received by the telecomputer can be stored on an electromagnetic storage medium such as tape, drum, floppy disc, hard disk drive, optical laser disc or other retention medium. The information may also be stored in volatile or non-volatile memory elements. In addition, the telecomputer can also be programmed to verify for the central paging mainframe computer the receipt of a high priority numeric or alphanumeric pager message. The device then shuts off all other systems of the telecomputer except the paging function while alerting the user by appropriate external audible or visual signal as to what is occurring.
