Abstract

A method and apparatus for reducing dormand-wakeup latency in a group communication network (100) provides for a significant reduction in the actual total dormant-wakeup time and the PTT{XE"PTT"} latency perceived by the talker through caching the network-initiated wakeup tiggers destined for target listeners, and delivering a wakeup trigger to a target mobile station (104, 1o6, 108) as soon as the target mobile station has re-established its traffic channel.

Claims

[c1] 1. A method for reducing latency in a group communication network, the method comprising:
receiving a dormant-wakeup trigger directed to a target communication device;
triggering the target communication device to re-establish its traffic channel; and storing the dormant-wakeup trigger for later transmission to the target communication device.

[c2] 2. The method of claim 1, further including:
transmitting the stored dormant-wakeup trigger to the target mobile as soon as the target mobile has re-established a traffic channel.

[c3] 3. 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 target communication device;
triggering the target communication device to re-establish its traffic channel; and storing the dormant-wakeup trigger for later transmission to the target communication device.

[c4] 4. The computer-readable medium of claim 3, wherein the method further includes:
transmitting the stored dormant-wakeup trigger to the target mobile as soon as the target mobile has re-established a traffic channel.

[c5] 5. An apparatus for reducing latency in a group communication network, comprising:
means for receiving a dormant-wakeup trigger directed to a target communication device;
means for triggering the target communication device to re-establish its traffic channel; and means for storing the dormant-wakeup trigger for later transmission to the target communication device.

[c6] 6. The apparatus of claim 1, further including:
means for transmitting the stored dormant-wakeup trigger to the target mobile as soon as the target mobile has re-established a traffic channel.

[c7] 7. 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 target communication device;
triggering the target communication device to re-establish its traffic channel; and storing the dormant-wakeup trigger for later transmission to the target communication device.

[c8] 8. The apparatus of claim 7, wherein the processor is further capable of:
transmitting the stored dormant-wakeup trigger to the target mobile as soon as the target mobile has re-established a traffic channel.
