Abstract
A digital radio network having a first single random access for packet data is enhanced by providing a second access which includes a second random access channel for controlled short data messages and a polled data channel for larger data messages. All mobiles operating within the system can access the first channel but only dual-mode mobiles can connect to the second access.
