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.
Claims4
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.
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.
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.
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.
