A METHOD AND APPARATUS FOR PREVENTING DEADLOCK IN A PUSH TALK DISPATCH SYSTEM

摘要

The present invention relates to a method and apparatus for preventing deadlock in a push talk system in order to prevent deadlock in a dispatch system wherein a set of remote units communicate with each other by broadcasting one at a time to the group, a base station receives a request to be system talker from a remote unit. The base station receives a grant to be system talker for the remote from a communications manager. The base station monitors a series of data from the remote unit to detect voice activity. The base station sends to the communications manager a surrogate request to desist as the system talker for the remote unit if the voice activity falls below a threshold.
