Abstract

Disclosed is a method for replicating information from a computer system (such as a personal computer) onto a cellular phone. This invention may be used to upload data streams into a cellular phone for a variety of purposes, such as upgrade of firmware, address book data, emergency contact information, synchronization of the internal clock, and so forth. According to the present invention, a simple low cost way is provided to (preferably) medium function cellular phone devices (i.e., those not implementing TCP/IP, Bluetooth or other advanced communication protocols), by establishing a dedicated point-to-point connection between a cellular phone and a computer system. This is accomplished by establishing a dedicated connection over the public switched telephone service, and then entering a transfer protocol between a computer and a cellular phone.

Method and apparatus for replicating information onto a cellular telephone

Disclosed is a method for replicating information from a computer system (such as a personal computer) onto a cellular phone. This invention may be used to upload data streams into a cellular phone for a variety of purposes, such as upgrade of firmware, address book data, emergency contact information, synchronization of the internal clock, and so forth.

In prior art, three methods have been used for transfer of data between a computer and a cellular phone: dedicated cabling between a computer and the cellular phone (e.g., a proprietary protocol or USB), a communication protocol such as infrared ports, or Bluetooth protocol wireless LAN, or Internet protocol communication (TCP/IP) provided over the cellular phone service,

These prior art methods for information transfer have a number of disadvantages, such as the need for expensive high function service (TCP/IP), expensive high function hardware (e.g., Bluetooth equipped computer and cellular phone, or IR ports, or cabling terminals and IO chips), or the need for establishing and manipulating special purpose cabling.

According to the present invention, a simple low cost way is provided to (preferably) medium function cellular phone devices (i.e., those not implementing TCP/IP, Bluetooth or other advanced communication protocols), by establishing a dedicated point-to-point connection between a cellular phone and a computer system. This is accomplished by establishing a dedicated connection over the public switched telephone service, and then entering a transfer protocol between a computer and a cellular phone.

In an optimized embodiment, the service protocol selected is comp...
