Abstract: Fast channel deployment is achieved amongst subscriber devices (SDs) having an incident scene role at an incident scene. An SD detects an incident scene arrival trigger associated with arrival at an incident scene. Responsive to detecting the incident scene arrival trigger, the SD (i) tunes to a pre-configured incident channel or (ii) scans a plurality of channels for an incident channel and tunes to the incident channel once located. The SD receives, via the incident channel, an incident scene role to traffic channel mapping that maps a particular incident scene role associated with the subscriber device to a particular assigned traffic channel on which subscriber devices associated with a same incident scene role may communicate. The SD tunes to the particular assigned traffic channel as a function of the incident scene role to traffic channel mapping.
