The currently proposed MIRS digital trunking system uses the message set shown in Figure 1. Arrows from the top indicate a'subscriber initiated message delivered through the infrastructure equip- ment to the digital trunking controller. Arrows from the bottom indicate messages originating from the trunking controller. Also, note that the horizontal distance is proportional to the processing time. This call set up scenario uses separate paging and group call grant message sets. It also delays the grant until a certain number of pages are received, or the page response timer expires. As you can see a large amount of time is spent identifying and sending page requests to trunking location areas, and waiting for a response.
