Abstract
Abstract A method for allocating communication resources within a communication system wherein communication resources are assigned only within critical sites and within non-critical sites containing critical users. A central controller checks the critical site list for allocating communication resources within the critical sites. No communication resources are allocated within non-critical sites that contain no critical users.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
170 words
A method for allocating communication resources within a communication system, wherein the communication system includes: a first communication site having a first coverage area; a second communication site having a second coverage area, wherein at least a part of the second coverage area is not coincident with the first coverage area; and a first group of communication units having a predetermined relationship with the first communication site, and wherein at least some of the first group of communication units have a predetermined status; the method comprising the steps of: when a communication is intended for the first group of communication units: (a) allocating communication resources within the first communication site to support the communication; (b) allocating communication resources to support the communication within the second site when at least one of the first group of communication units having the predetermined status is then being serviced by the second communication site, but not when only communication units not having the predetermined status are then being serviced by the second communication site.
