摘要

A method and apparatus for circuit-switched and single-user traffic channel packet data communication in a cellular radiotelephone system, including a base station (10) and mobile data unit (5) both operable for establishing either a circuit-switched data call connection or a single-user connectionless packet data traffic channel via a radio channel (7), and communicating packet data over the established radio channel.
