Abstract
A method and apparatus for reducing latency in a group communication network provides for a significant reduction in the actual total dormancy wakeup time and the PTT latency by exchanging group call signaling even when mobiles are dormant and no traffic channel is active. The method and apparatus provides for exchanging the group call signaling through the use of the short data burst (SDB) message signaling. The method and apparatus provides for re-establishing dedicated traffic channels for the talker mobile and the dormant listener mobiles advantageously in parallel.
Claims52
In a communication device, a method for reducing latency in a group communication network, the method comprising:
- receiving a floor-control request from a user of the communication device who wishes to initiate a group call;
- and
- transmitting the floor-control request on a reverse common channel of a wireless network to a controller.
In a communication device, a computer-readable medium embodying a method for reducing latency in a group communication network, the method comprising:
- receiving a floor-control request from a user of the communication device who wishes to initiate a group call;
- and
- transmitting the floor-control request on a reverse common channel of a wireless network to a controller.
A communication device for reducing latency in a group communication network, comprising:
- means for receiving a floor-control request from a user of the communication device who wishes to initiate a group call;
- and
- means for transmitting the floor-control request on a reverse common channel of a wireless network to a controller.
A communication device for reducing latency in a group communication network, the communication device comprising:
- a receiver;
- a transmitter;
- and
- a processor communicatively coupled to the receiver and the transmitter, the processor being capable of:
- receiving a floor-control request from a user of the communication device who wishes to initiate a group call;
- and
- transmitting the floor-control request on a reverse common channel of a wireless network to a controller.
