Method and apparatus for moving primary control of a call in a multiple site communication system
First Claim
Patent Images
1. A method comprising the steps of:
- receiving, by a communication resource controller in a first site of a plurality of sites that comprise a communication system, a communication service request from a communication unit;
determining, by the communication resource controller, that the communication service request requires use of a communication resource in a second site of the plurality of sites;
initiating, by the communication resource controller while acting as a primary controller, a call to support the communication service request;
determining, by the communication resource controller, that primary control of the call should be moved from the first site; and
moving, by the communication resource controller, primary control of the call to the second site to continue supporting the call.

Abstract
Resource controllers (14) within a multisite communication system (20) selectively and automatically assume primary (45) and secondary (53) control modes of operation in order to ensure that adequate communication resources are assigned throughout the system at necessary sites in order to include talk group members that are dispersed throughout the system.

1. A method comprising the steps of:
-
receiving, by a communication resource controller in a first site of a plurality of sites that comprise a communication system, a communication service request from a communication unit; determining, by the communication resource controller, that the communication service request requires use of a communication resource in a second site of the plurality of sites; initiating, by the communication resource controller while acting as a primary controller, a call to support the communication service request; determining, by the communication resource controller, that primary control of the call should be moved from the first site; and moving, by the communication resource controller, primary control of the call to the second site to continue supporting the call. - View Dependent Claims (2, 3, 4)

5. A communication system that includes a plurality of communication resource controllers, comprising:
-
a) a first communication resource controller that controls allocation of communication resources in a first site, wherein the first communication resource controller selectively supports calls as a primary controller and as a secondary controller; b) a second communication resource controller that controls allocation of communication resources in a second site, wherein the second communication resource controller selectively supports calls as a primary controller and as a secondary controller, and wherein when the first communication resource controller is supporting a call as a primary controller, the second communication resource controller is supporting the call as a secondary controller; and c) a communication link coupling the first communication resource controller and the second communication resource controller, wherein the communication link provides a medium through which the first communication resource controller instructs the second communication resource controller to allocate a communication resource in the second site to support the call. - View Dependent Claims (6)

7. In wide coverage area, multiple site radio communication system, a method comprising the steps of:
-
at a firs communication resource controller in a first site within the communication system; receiving a service request from a communication unit seeking to make a call; determining that the service request requires use of communication resources in at least a second site of the radio communication system in order to include at least one target communication unit; while acting as a primary controller, initiating a call to support the service request by at least causing a second communication resource controller at the second site to allocate a communication resource to support the call; determining that primary control of the call should be moved to the second communication resource controller in the second site to continue supporting the call; moving primary control of the call to the second communication resource controller in the second site to continue supporting the call. - View Dependent Claims (8)

9. A method comprising the steps of:
-
receiving, by a communication resource controller in a first site of a plurality of sites that comprise a communication system, a communication service request from a communication unit; determining, by the communication resource controller, that the communication service request requires use of a communication resource in a second site of the plurality of sites; initiating, by the communication resource controller while acting as a primary controller, a call to support the communication service request; determining, by the communication resource controller, that primary control of the call should be moved from the first site; and moving, by the communication resource controller, primary control of the call to a third site of the plurality of sites to continue supporting the call. - View Dependent Claims (10, 11)
