Automatic control channel acquisition method and apparatus in a trunked communication system
First Claim
1. A method for automatically acquiring, at least in part, a system resource for a trunked communication system having a limited number of system resources, a plurality of communication units, at least one primary communication control resource having a first geographic communication coverage area, and at least one secondary communication control resource, wherein at least two system resource listings are utilized, the method comprising the steps of:
- A) a first searching for a system resource in a first listing of system resourceswherein the first searching comprises at least the steps of;
1A) first seeking a system resource on a first listing;
1B) second seeking a next system resource on the first listing when a system resource previously sought on the first listing is not available;
1C) reiterating steps (1A) and (1B) above until one of;
finding at least one available system resource on the first listing; and
finding that all system resources in the first listing are not available;
B) a second searching for a system resource in a second listing of system resources when no system resource is available in the first listingwherein the second searching comprises at least the steps of;
2A) first seeking a system resource on a second listing;
2B) second seeking a next system resource on the second listing when a system resource previously sought on the second listing is not available;
2C) reiterating steps (2A) and (2B) above until one offinding at least one available system resource on the second listing; and
finding that all system resources in the second listing are not available; and
C) automatically acquiring at least one system resource relative to searching in at least one listing.

Abstract
A trunked communication system automatic system resource acquisition method and apparatus provide for utilizing dual system resource listings to monitor for priority communications within a primary geographic communication control area. System resources on a second listing have secondary geographic coverage areas substantially within a primary geographic communication control area, allowing communication units to receive priority transmission preferentially from secondary control system resources in a first listing and secondarily from primary control system resources in a second listing when secondary control system resources are not available.
