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 determining whether the communication device has been inactive for a predetermined first time period and, if so, causing the communication device to enter a control-hold mode, wherein the communication device maintains its dedicated traffic channel. The method further includes the steps of determining whether the communication device has been in the control-hold mode for a predetermined second time period and, if so, causing the communication device to enter a dormant mode, wherein the communication device releases its dedicated traffic channel. The method and apparatus further provides for causing the communication device to cache its service configuration state before entering the dormant mode.
