Method and apparatus for trunking radio frequency resources

摘要

A subscriber unit in a two-way radio frequency communications system monitors a first channel currently serving as a rest channel for the system, wherein the channel currently serving as the rest channel for the system is monitored by subscribers that are idle in the system. The subscriber unit transmits a first call on the first channel if the first channel is idle at the start of the first call. Once the first call ends, the subscriber unit receives an identity of a second channel that is currently serving as the rest channel for the system when the call ends. If the first subscriber unit becomes idle after the first call ends, then it monitors the second channel.
