Method and apparatus for reducing latency in waking up a group of dormant communication devices
First Claim
Patent Images
1. A method for reducing latency in a group communication network, the method comprising:
- receiving a dormant-wakeup trigger directed to a dormant target communication device;
triggering the dormant target communication device to re-establish its traffic channel;
temporarily storing the dormant-wakeup trigger for later transmission to the dormant target communication device; and
transmitting the stored dormant-wakeup trigger to the target communication device as soon as the target communication device has re-established its traffic channel.

Abstract
A method and apparatus for reducing dormant-wakeup latency in a group communication network provides for a significant reduction in the actual total dormant-wakeup time and the PTT latency perceived by the talker through caching the network-initiated wakeup triggers destined for target listeners, and delivering a wakeup trigger to a target mobile station as soon as the target mobile station has re-established its traffic channel.
