Wide area trunked channel busy override
First Claim
1. In a trunked communication system having communication units that are arranged into communication groups, communication sites, communication resources, and a communication resource allocator, wherein each of the communication sites is assigned at least some of the communication resources, a method for overriding a communication site busy condition comprises the steps of:
- a) initiating, by a requesting communication unit of a communication group, a request for a group call;
b) establishing, by the communication resource allocator, the communication site busy condition when a communication resource is not available for allocation in at least one communication site; and
c) allocating, by the communication resource allocator, communication resources in the communication sites that have an available communication resource when a communication resource is available in the communication site that the requesting communication unit is located in and when a busy override signal is initiated.

Abstract
A typical multi-site trunked communication system comprises communication units that are arranged into talk groups, communication resources distributed among communication sites, and a communication resource allocator. In such a system, a methodology is incorporated that allows communication units to override communication site busy conditions, where the communication site busy conditions prohibits placement of group calls until all communication sites have an available communication resource. The communication site busy condition may be overridden by a communication unit by initiating a busy override signal. Once the busy override signal is initiated, the communication resource allocator allocates, in each site, a communication resource to the communication group of the requesting communication unit.

-
a) initiating a request for a group call; b) receiving a communication site busy signal from the communication resource allocator when a communication resource is not available for allocation in at least one communication site; and c) initiating a busy override signal when a communication resource has been allocated in the communication site that the requesting communication unit is located in and when the requesting communication unit is enabled to initiate the busy override. - View Dependent Claims (8, 9, 10, 11)
