Abstract
A method and device for improved audio intelligibility in a converged land mobile radio (LMR)/broadband (BB) communications system is provided. A converged portable radio operating as part of a talkgroup in the LMR/BB system checks for predetermined triggers during standby that could cause receive radios of the talkgroup to receive degraded audio. If such a trigger is detected then the converged portable radio switches from the LMR system to the BB system and transmits a notification including a change system message to the other converged portable radios of the talkgroup. The notification is transmitted prior to any push-to-talk audio being transmitted from the originating radio. The converged portable radio can transmit, via a push-to-talk switch, narrowband (NB) audio and wideband (WB) audio in parallel over the BB system to the talkgroup subsequent to the detection of triggers and the sending of the notification.
