Abstract
A multi-system priority scan process including maintaining, at a mobile station (MS), a scan list including channels associated with talkgroups, the talkgroups including one or more trunked radio system talkgroups and one or more conventional radio system talkgroups. The MS negotiates, with a trunked radio system, a working channel for a particular trunked radio system talkgroup out of the trunked radio system talkgroups, the working channel being a traffic channel that the trunked radio system will first attempt to assign a call for that talkgroup. During a subsequent scan for talkgroup for activity associated with the particular trunked radio system talkgroup, the MS switches to the working channel and determines if a carrier is present on the working channel, without switching to a control channel of the trunked radio system to scan for activity associated with the particular trunked radio system talkgroup.
