Wireless communication system utilizing a persistence value for group communication requests to reduce latency
First Claim
1. A system for minimizing latency for direct group communications among a group of wireless telecommunication devices on a wireless network, comprising:
- a plurality of wireless telecommunication devices wherein each wireless telecommunication device is able to direct a single group communication stream to a designated group of the plurality of wireless telecommunication devices, each wireless telecommunication device selectively requesting and then receiving an open dedicated broadcast channel for an outgoing communication from the wireless telecommunication device, to include a direct communication stream from that wireless telecommunication device; and
a communication server that receives the single communication stream from a communicating wireless device and creates a group communication to all wireless telecommunication devices of the designated group, wherein a set of one or more of the plurality wireless telecommunication devices selectively receives a broadcast channel based upon a predetermined probability, and one or more of the set of wireless telecommunications devices assigns a greater probability of receiving an open broadcast channel for requests to transmit direct group communication streams than for requests to open a broadcast channel that are not for a direct group communication.

Abstract
A system and method for minimizing latency for direct group communications, such as push-to-talk (PIT) calls, among a group of wireless telecommunication devices on a wireless telecommunication network. The wireless telecommunication device selectively requests and then receives an open dedicated broadcast channel for an outgoing communication, which can include a direct group communication stream to a communication server that receives and creates a group communication to all wireless telecommunication devices of the designated group. The wireless telecommunication devices selectively receives a broadcast channel based upon a predetermined probability, and assigns a greater probability of receiving an open broadcast channel for requests to transmit direct group communication streams than for requests open a broadcast channel that are not for a direct group communication.

- 6. A wireless telecommunication device that is able to direct a single group communication stream to a designated group of a plurality of wireless telecommunication devices on wireless telecommunication network, the wireless telecommunication device selectively opening dedicated broadcast channels to the wireless telecommunication network for an outgoing communication from the wireless telecommunication device, to include any direct communication stream from that wireless telecommunication device, and wherein the wireless telecommunication device further selectively opens dedicated broadcast channels based upon a predetermined probability, and assigns a greater probability of opening a broadcast channel for transmitting a direct group communication stream than for opening a broadcast channel not for a direct group communication stream.

11. A wireless telecommunication device, comprising:
-
a means for directing a single group communication stream to a designated group of a plurality of wireless telecommunication devices on wireless telecommunication network;
a means for selectively opening dedicated broadcast channels to the wireless telecommunication network for an outgoing communication from the wireless telecommunication device, to include any direct communication stream from that wireless telecommunication device; and
a means for selectively opening the dedicated broadcast channel based upon a predetermined probability;
the means assigning a greater probability of opening a broadcast channel for transmitting a direct group communication stream than for opening a broadcast channel not for a direct group communication stream.

12. A method for minimizing latency for direct group communications from a first wireless telecommunication device to a predetermined group of wireless telecommunication devices on a wireless network, comprising the steps of:
-
requesting, at a wireless telecommunication device that is able to direct a single group communication stream to a designated group of a plurality of wireless telecommunication devices on wireless telecommunication network, the opening of a dedicated broadcast channel to the wireless telecommunication network for an outgoing communication from the wireless telecommunication device;
assigning a first probability of opening a direct communication stream;
assigning a second probability for opening a direct communication stream for a direct group communication stream, the second probability greater than the first probability;
if the request for a dedicated broadcast channel is not for a direct group communication stream, selectively opening a dedicated broadcast channel based upon the first probability; and
if the request for a dedicated broadcast channel is for a direct group communication stream, selectively opening dedicated broadcast channel based upon the second probability. - View Dependent Claims (13, 14, 15, 16)

18. A computer program that, when executed on the computer platform of a wireless telecommunication device, minimizes latency for direct group communications from that wireless telecommunication device to a predetermined group of wireless telecommunication devices on a wireless network, the program causing the wireless device to perform the steps of:
-
requesting the opening of a dedicated broadcast channel to the wireless telecommunication network for an outgoing communication from the wireless telecommunication device;
assigning a first probability of opening a direct communication stream;
assigning a second probability for opening a direct communication stream for a direct group communication stream, the second probability greater than the first probability;
if the request for a dedicated broadcast channel is not for a direct group communication stream, selectively opening a dedicated broadcast channel based upon the first probability; and
if the request for a dedicated broadcast channel is for a direct group communication stream, selectively opening dedicated broadcast channel based upon the second probability. - View Dependent Claims (19, 20, 21, 22)
