Method of handling busy calls in a multiple zone communication system
First Claim
1. A method comprising the steps of:
- issuing a request to participate in a call to one or more participating zones of a plurality of zones in a communication system, wherein each of the plurality of zones is comprised of a plurality of communication sites;
concluding that at least one zone of the one or more participating zones is unable to grant the call, thereby resulting in a busy status for the call;
informing the one or more participating zones of the busy status;
obtaining, by a first zone of the one or more participating zones, at least one communication resource necessary to grant the call;
issuing, by the first zone, a resource available notification;
receiving the resource available notification from the first zone;
determining if a first predetermined number of the one or more participating zones have indicated ability to grant the call;
when a second predetermined number of the one or more participating zones has not indicated ability to grant the call, issuing a still busy notification to the first zone, which still busy notification indicates that the call still has a busy status;
upon receiving the still busy notification, returning, by the first zone, the at least one communication resource for possible allocation to another call.

Abstract
A method of handling busy calls, performed by a controlling entity (ZC1) in a multiple-zone system, includes the steps of issuing (201) a request to participate in a call to one or more participating zones (101, 103, and 105) and concluding (203) that at least one zone of the participating zones (101, 103, and 105) is unable to grant the call, thereby resulting in a busy status for the call. The controlling entity (ZC1) informs the participating zones (101, 103 and 105) of the busy status. A resource available notification is received (209) from a first zone, and the controlling entity (ZC1) determines (211) if a predetermined number of the participating zones (101, 103, and 105) have indicated ability to grant the call. When at least one zone of the one or more participating zones has not indicated ability to grant the call, the controlling entity (ZC1) issues (213) a still busy notification to the first zone, which still busy notification indicates that the call still has a busy status.
