Method and apparatus for monitoring link activity to prevent system deadlock in a dispatch system |
摘要 |
Method and apparatus to prevent system deadlock in a dispatch system by monitoring link activity. The dispatch system is comprised of a set of remote units which communicate with each other by broadcasting one at a time to the group. A remote unit communicates with the other remote units through at least one base station. A communications manager grants a remote unit exclusive system talker status upon request through the base station servicing the requesting remote unit. The base station monitors a series of data from the remote unit designated as the system talker to detect voice activity. The base station sends a surrogate request to the communications manager to relinquish the system talker privilege if the voice activity falls below a predetermined threshold. |
