Retaining traffic channel assignments for satellite terminals to provide lower latency communication services
First Claim
Patent Images
1. A wireless communications method comprising:
- assigning a traffic channel for use by a terminal to transmit data traffic to a satellite for relay to a satellite base station; and
retaining the traffic channel assignment for use by the terminal while the terminal is idle between data traffic transmissions to the satellite in response to a type of service designation that is associated with the terminal and indicates that the terminal is to be provided reduced latency push-to-talk (PTT) protocol service.

Abstract
A traffic channel is assigned for use by a terminal to transmit data traffic to a satellite for relay to a satellite base station. The traffic channel assignment is retained for use by the terminal while the terminal is idle between data traffic transmissions to the satellite in response to a type of service designation that is associated with the terminal.

19. A wireless communication system comprising:
a satellite base station that is configured to assign a traffic channel for use by a terminal to transmit data traffic to a satellite for relay to the satellite base station, and to retain the traffic channel assignment for use by the terminal while the terminal is idle between data traffic transmissions to the satellite in response to a type of service designation that is associated with the terminal and indicates that the terminal is to be provided reduced latency push-to-talk (PTT) protocol service. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A wireless communication system comprising:
-
a terminal that is configured to receive from a satellite base station a traffic channel assignment for use by the terminal to transmit data traffic to a satellite for relay to the satellite base station and a command that indicates whether the traffic channel assignment is to be retained while idle, and to retain the traffic channel assignment for use by the terminal while the terminal is idle between data traffic transmissions to the satellite in response to the command indicating that the assignment is to be retained while idle, wherein the terminal is further configured to;
1) respond to each of a sequence of user activations of a push-to-talk (PTT) switch of the terminal by transmitting voice data traffic through the retained traffic channel assignment without waiting for assignment of another traffic channel to the terminal by the satellite base station; and
/or
2) respond to generation of each of a sequence of Voice-Over-Internet Protocol (VOIP) data traffic from voice that is sensed by a microphone of the terminal by transmitting the VOIP data traffic from the terminal through the retained traffic channel assignment without waiting for assignment of another traffic channel to the terminal by the satellite base station. - View Dependent Claims (35, 36, 37)
