摘要：A method and apparatus for providing an efficient dormant mode for push-to-talk communication devices in a group communication network provides for determiningwhether the communication device has been inactive for a predetermined first timeperiod and, if so, causing the communication device to enter a control-hold mode,wherein the communication device maintains its dedicated traffic channel. The methodfurther includes the steps of determining whether the communication device has been inthe control-hold mode for a predetermined second time period and, if so, causing thecommunication device to enter a dormant mode, wherein the communication devicereleases its dedicated traffic channel. The method and apparatus further provides forcausing the communication device to cache its service configuration state before enteringthe dormant mode.
