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.

Abstract: A method and apparatus are provided by which a radio communication device relays emergency signals across different channels using dual-watch. A dual-watch primary receiver of the radio communication device is allocated to a user selected home channel, while a dual-watch secondary receiver continually scans a pre-stored list of secondary channels for the purpose of detecting a possible emergency signal. The radio communication device upon detecting an emergency signal in either the home channel or any of the scanned secondary channels, relays the emergency signal to all the channels present in the radio communication device's channel list, except for the originating channel.

Abstract: A device, method and system for scanning communication systems of different types is provided. A mobile device comprises: first and second transceivers to communicate first and second communication systems of different types; a memory storing first and second scan lists for scanning first and second channels on the first and second communication systems; and a controller configured to: communicate, using the first transceiver, an indication of the first and second scan lists to a gateway device configured as a proxy for the mobile device to communicate with the first communication systems; receive, using the first transceiver, from the gateway device, a reply indicating that the gateway device is capable of scanning the first communication systems using the first scan list, but is not capable of scanning the second communication systems; and control the second transceiver to scan the one or more second communication systems using the second scan list.

Abstract: Some example communication systems include a fixed network equipment (FNE) operable to receive a talk group call from a first radio. The FNE is operable to transmit the talk group call to a second radio. The FNE is operable to receive a request for a high priority call. The communication system includes a gateway operable to transmit an interrupt signaling message through a broadband channel to the first radio. The interrupt signaling message includes instructions to de-key from the talk group call. Some example communication systems include a first radio operable to communicate with a second radio in a talk group call. The communication system includes a gateway operable to receive a request for a high priority call. The gateway is operable to transmit an interrupt signaling message through a broadband channel to the first radio. The interrupt signaling message includes instructions to make a high priority call decision.
