Abstract
A data message transmission system for a cellular radiotelephone system is disclosed. Data to be transmitted is converted into a format compatible with radio transmission prior to transmission. The data is reconverted to its original format following reception. Handoff is accomplished by halting the data transmission prior to handoff and resuming data transmission after handoff. Call supervision occurs via busy-idle bit coding.
