Abstract

Today's conventional data systems allow a sub- scriber to roam between channels at a site as well as between channels on different sites while maintain- ing all necessary connectivity. In an integrated voice / data environment the moment a subscriber roams to a different data channel it looses contact both with the voice infrastructure / console as well as with other members of its subscriber talk group. Unlike Trunking there is no control channel in a conventional system to command all voice users of a talk group to change to a common channel for each call.
