Abstract

Communication between tasks within repeaters of a communication system can be improved in the following manner. Each repeater determines its repeater configuration which includes identifying any peripheral devices affiliated with the repeater. Next the repeaters establish which repeater will be the master repeater based on a predetermined protocol. A predetermined number of tasks is allocated among the repeaters based on which repeater is established as the master repeater and each repeater configuration. Finally, message routing tables are created based on the allocated trunking tasks, peripheral devices, and communication system configuration. The message routing tables are used in routing messages between tasks in the communication system.

Claims

1. In a communication system that includes a limited number of repeaters, a plurality of peripheral devices, and a local area network, LAN, wherein each of the limited number of repeaters are operably coupled to one another via the LAN, a method for establishing communication between the limited number of repeaters, the method comprises the steps of:

a) determining, by each of the limited number of repeaters, repeater configuration information, wherein the repeater configuration information includes information pertaining to which peripheral devices of the plurality of peripheral devices are affiliated with the repeater;

b) establishing a master repeater of the limited number of repeaters at power up or after a failure based on a predetermined protocol; and

c) allocating a predetermined number of tasks among the limited number of repeaters based upon which repeater is established as the master repeater and the repeater configuration information of each of the limited number of repeaters.

2. The method of claim 1 further comprises, when a repeater is added to the communication system, activating at least one predetermined task within the added repeater based on the peripheral devices affiliated with the added repeater.

3. The method of claim 1 further comprises, when one of the limited number of repeaters becomes inactive to produce an inactive repeater,

determining whether the inactive repeater was allocated at least one system wide task of the predetermined number of tasks;

and

when the inactive repeater was allocated at least one system wide task, allocating the at least one system wide task to at least one of the other limited number of repeaters based on a second predetermined protocol.

4. In the method of claim 1, step (c) further comprises allocating a call processing task of the predetermined number of tasks to the master repeater.

5. The method of claim 1 further comprises modifying, for a particular repeater of the limited number of repeaters, allocation of peripheral device tasks of the predetermined number of tasks based upon addition or deletion of a peripheral device to the particular repeater.

6. The method of claim 1 further comprises, when the communication system is coupled into a network of communication systems, wherein the network includes a zone controller, activating, within one of the limited number of repeaters, a peripheral device task of the predetermined number of tasks to interface the communication system with the zone controller.

7. In a communication system that includes a limited number of repeaters, a plurality of peripheral devices, and a local area network, LAN, wherein the limited number of repeaters are operably coupled to one another via the LAN, a method for communicating information throughout the communication system, the method comprises the steps of:

a) receiving, by a particular repeater of the limited number of repeaters, a message generated by a peripheral device that is affiliated with the particular repeater;

b) determining, by the particular repeater, whether the message contains information that requires the particular repeater to perform at least one predetermined task;

c) when the message contains information that requires the particular repeater to perform the at least one task, performing the at least one predetermined task by the particular repeater;

d) when the message does not contain information that requires the particular repeater to perform the at least one task, transmitting the message on the LAN; and

e) upon receiving the message from the LAN, determining, by at least a second repeater of the limited number of repeaters, whether the message contains information that requires the second repeater to perform at least one predetermined task.

8. In the method of claim 7, step (c) further comprises, after the at least one predetermined task is performed to produce tasked information, determining whether to route the tasked information to the LAN or to a peripheral device affiliated with the particular repeater.

9. The method of claim 7 further comprises, when the message contains information that requires the second repeater to perform the at least one predetermined task, performing, by the second repeater, the at least one predetermined task to produce tasked information.

10. The method of claim 9 further comprises determining whether to route to tasked information to the LAN or to a peripheral device affiliated with the second repeater.

11. An improved repeater that is used in a communication system, wherein the communication system includes a limited number of improved repeaters, a plurality of peripheral devices, and a local area network, LAN, wherein the limited number of improved repeaters are operably coupled to one another via the LAN, wherein the improvement comprises:

task means for storing and executing at least one task of a predetermined number of tasks;

interface means for coupling the repeater to the local area network;

receiver means for receiving messages from peripheral devices that are affiliated with the repeater; and

task determination means, operably coupled to the task means, the receiver means, and the interface means, for determining whether messages on the LAN or messages received by the receiver means contain information that require the task means to perform one of the at least one task.
