Abstract:
A method for transmitting a facsimile between a code division multiple access (CDMA) cellular network having a mobile station and a base station having one of a CDMA cellular network and a different network, said method comprising the steps of:a. recognizing a modem command or modem configuration and call establishment using a data terminal in the mobile station comprising upper layer protocols including an application software, an application interface, a transport control protocol, an internet control message protocol, an internet protocol, and a point-to-point protocol, storing the modem command until a modem is acquired using the data terminal, and requesting a facsimile call using the data terminal with a modem dial command to a mobile terminal in the mobile station having a facsimile modem and lower layer protocols including a radio link protocol and a CDMA traffic channel;b. setting up a call connection between the base station and the mobile terminal following call processing and acquiring the facsimile modem from the base station;c. transmitting a facsimile image data encapsulated by the upper layer protocols from the data terminal to the mobile terminal;d. encapsulating and segmenting the facsimile image data using the lower layer protocols and transmitting the encapsulated and segmented facsimile image data from the mobile terminal to the base station; ande. recognizing the encapsulated and segmented facsimile image data at the base station, removing the upper and lower layer protocols from the encapsulated and segmented facsimile image data to reveal the raw facsimile image data, converting raw facsimile image data and transmitting the converted raw facsimile image data to a fax terminal.
