Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
72 words
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.
Claim 2
Independent Claim
72 words
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.
Claim 3
Dependent Claim
76 words
A computer-readable medium embodying 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.
Claim 4
Dependent Claim
76 words
A computer-readable medium embodying 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.
Claim 5
Independent Claim
81 words
The apparatus of An apparatus for reducing latency in a group communication network, comprising: means for receiving a dormant-wakeup trigger directed to a dormant target communication device; means for triggering the dormant target communication device to re-establish its traffic channel; means for temporarily storing the dormant-wakeup trigger for later transmission to the dormant target communication device; and means for transmitting the stored dormant-wakeup trigger to the target communication device as soon as the target communication device has re-established its traffic channel.
Claim 6
Independent Claim
81 words
The apparatus of An apparatus for reducing latency in a group communication network, comprising: means for receiving a dormant-wakeup trigger directed to a dormant target communication device; means for triggering the dormant target communication device to re-establish its traffic channel; means for temporarily storing the dormant-wakeup trigger for later transmission to the dormant target communication device; and means for transmitting the stored dormant-wakeup trigger to the target communication device as soon as the target communication device has re-established its traffic channel.
Claim 7
Independent Claim
99 words
An apparatus for reducing latency in a group communication network, the communication device comprising: a memory unit; a receiver; a transmitter; and a processor communicatively coupled to the memory unit, the receiver, and the transmitter, the processor being capable of: 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.
Claim 8
Independent Claim
99 words
An apparatus for reducing latency in a group communication network, the communication device comprising: a memory unit; a receiver; a transmitter; and a processor communicatively coupled to the memory unit, the receiver, and the transmitter, the processor being capable of: 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.
