A technique for transmission of wireless signals across CDMA radio links. Bandwidth is allocated dynamically within a session to specific CDMA subscriber unit based upon data rate determinations. Specifically, a dynamic bandwidth allocation algorithm operates from limits calculated based upon available ports per subscriber, expected user bandwidth, and parallel user bandwidth versus throughput. Provisions for priority service, unbalanced forward and reverse spectrum utilization, voice prioritization, and band switching are also made.

[ What is claimed is:] [1.] A method for providing wireless communication of digital data signals, the digital data signals being communicated between a plurality of wireless subscriber units, and a base station, the digital signals being communicated using at least one radio frequency channel via digitally modulated Code Division Multiple Access (CDMA) signals, the digitally modulated CDMA signals also having a given nominal data rate, the method comprising the steps of:a) making available a plurality of subchannels within each CDMA radio channel, wherein a data rate of each subchannel is much less than the nominal data rate of the digitally modulated CDMA radio signals;b) establishing a network layer session between terminal equipment connected to the subscriber unit through the base station to other terminal equipment connected to the base station; andc) during the network layer session, allocating available subchannels only on an as needed basis, with the number of subchannels allocated thereby changing during the duration of a given session and such that even when no digital signals are present during the session connection, subchannels are deallocated from the connection while maintaining the appearance of a continuous session connection at the network layer.
