Communication device for providing an efficient dormant mode for a group communication network
First Claim
1. In a communication device operating in a group communication network, a method for putting the communication device into a dormant mode, the method comprising:
- determining whether the communication device has been inactive for a predetermined first time period;
if it is determined that the communication device has been inactive for the predetermined first time period, causing the communication device to enter a control-hold mode, wherein the communication device maintains its dedicated traffic channel;
determining whether the communication device has been in the control-hold mode for a predetermined second time period; and
if it is determined that the communication device has been in the control-hold mode for the predetermined second time period, causing the communication device to enter a dormant mode, wherein the communication device releases its dedicated traffic channel.

Abstract
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.

7. A communication device for providing a dormant mode, comprising:
-
a receiver to receive information over the network;
a transmitter to transmit information over the network; and
a processor communicatively coupled to the receiver and the transmitter, the processor being capable of;
determining whether the communication device has been inactive for a predetermined first time period;
if it is determined that the communication device has been inactive for the predetermined first time period, causing the communication device to enter a control-hold mode, wherein the communication device maintains its dedicated traffic channel;
determining whether the communication device has been in the control-hold mode for a predetermined second time period; and
if it is determined that the communication device has been in the control-hold mode for the predetermined second time period, causing the communication device to enter a dormant mode, wherein the communication device releases its dedicated traffic channel. - View Dependent Claims (8)
