摘要： A method and system for operational improvements in a dispatch console in a multi-source environment includes receiving (310) a plurality of audio streams simultaneously from a plurality of mobile devices, transcribing received audio streams by the means of speech-to-text conversion, presenting real-time transcriptions to the user and determining (320) if a first keyword is present in at least one of the plurality of audio and/or text streams. Upon determining the presence of the first keyword, the dispatch console automatically performs (330) at least one predefined dispatch console operation from a list of predefined dispatch console operations. The dispatch console further receives (340) a second keyword based on determining the presence of the first keyword and checks (350) for the presence of the second keyword within the audio and/or text streams thereby enabling additional automated dispatch console operations.

摘要： A wireless communication system (300) includes a wireless serving communication unit (322) serving a plurality of remote units (312-316) with a communication resource (318-320). The at least one wireless serving communication unit (322) includes a transmitter (421) for transmitting data on an outbound communication resource, and a receiver (422) for receiving a communication on an inbound communication resource, wherein said inbound and outbound communication resources have a variable communication resource offset.
