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 for a device to provide emergency information is provided herein. During operation, an emergency responder will send out a wireless request for ICE information. Any device in the area will wirelessly respond to the request by providing ICE information, as long as a predetermined criterion is met. Because ICE information can be requested, and obtained wirelessly, a first responder does not need physical access to the device storing the ICE information. Thus, ICE information can be obtained from a device even when the device is not immediately accessible to the first responder.
