Abstract
Within a two way radio frequency communication system, a repeater transmits an identity of a rest channel when transmitting during an active communication call on a channel other than the rest channel. A subscriber unit communicating within the active communication, receives the identity of the rest channel, leaves the active communication; and initiates a new communication on the rest channel.
Claims18
A method of operation of a wireless communication device operating in a trunked radio system having a rest channel on which idle wireless communication devices reside and await new call notifications, the method comprising:
- participating in a first call on a first channel in the trunked radio system;
- periodically receiving an identity of the rest channel on the first channel while participating within the first call;
- responsive to detecting a request to begin a new second call, leaving the first call on the first channel, switching to the rest channel, and initiating the new second call on the rest channel.
A method of operation of a two way radio frequency communication system, the method comprising:
- within a repeater operating within the two way radio frequency communication system:
- transmitting an identity of a current rest channel within at least one of a Common Announcement Channel (CACH) message and a Control Signaling Block (CSBK) message during an active communication call on another channel;
- and
- within a subscriber unit operating within the two way radio frequency communication system:
- communicating within the active communication on the another channel;
- receiving the identity of the rest channel on the another channel within the at least one of the Common Announcement Channel (CACH) message and the Control Signaling Block (CSBK) message from the repeater;
- leaving the active communication;
- and
- initiating a new communication on the rest channel.
