Abstract
In a mobile radio communications system, critical signaling messages, e.g., handoff messages, transmitted on a fast associated control channel and/or a slow associated control channel belonging to a digital traffic channel, are more heavily data protected than speech using convolutional coding and interburst interleaving. The coding and interburst interleaving are carried out so as to maintain compatibility with an exiting frame structure.
