Abstract
A subscriber unit 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 determines that a first call is being initiated on the first channel. If the first call is not of interest, the subscriber unit ceases to monitor the first channel, and monitors a second channel that will serve as the rest channel for the system when the first call starts on the first channel. If the first call is of interest, the subscriber unit participates in the first call on the first channel, and before or after the first call ends, participates in a second call on a third channel or monitors a channel currently serving as the rest channel for the system when the subscriber unit becomes idle.
