1. A method for controlling a transmit channel of a push-to-talk wireless device, the method comprising:
- receiving parameters comprising;
(a) a maximum talk time (MTT) that represents an amount of time the push-to-talk wireless device can continuously occupy the transmit channel; and
(b) a back off time (BOT);
being granted the transmit channel;
after upon continuously occupying the transmit channel for the MTT, the push-to-talk wireless device automatically releasing the transmit channel thereby allowing another device to occupy the transmit channel;
after automatically releasing the transmit channel, starting a BOT timer; and
waiting until expiry of the BOT timer before transmitting a request for the transmit channel.

Abstract
Systems and methods are provided for controlling transmit channel utilization in systems providing walkie-talkie-like communications to wireless devices. Parameters such as a maximum talk time and back off time are provided to each wireless device to control how long they can continuously occupy the talk channel, and to control how soon after releasing the talk channel they can again access the talk channel.

4. A push-to-talk wireless device comprising:
-
a processing element configured to control a transmit channel of the push-to-talk wireless device by; receiving parameters comprising; (a) maximum talk time (MTT) that represents an amount of time the push-to-talk wireless device an automatically occupy the transmit channel; and (b) a back off time (BOT); being granted the transmit channel; upon continuously occupying the transmit channel for the MTT, the push-to-talk wireless device automatically releasing the transmit channel thereby allowing another device to occupy the transmit channel; after automatically releasing the transmit channel, starting a BOT timer; and waiting until expiry of the BOT timer before transmitting a request for the transmit channel. - View Dependent Claims (5, 6)

7. A method for controlling a transmit channel of a push-to-talk wireless device, the method comprising:
- sending parameters comprising;
(a) a maximum talk time (MTT) that represents an amount of time the push-to- talk wireless device can continuously occupy the transmit channel; and
(b) a back off time (BOT) representing a minimum time after the release of the transmit channel before the push-to-talk wireless device can again request the transmit channel; and
granting the transmit channel;
wherein upon the transmit channel being continuously occupied for the MTT, the transmit channel is automatically released thereby allowing another device to occupy the transmit channel. - View Dependent Claims (8, 9)

10. An apparatus comprising:
-
a talk control element configured to control a transmit channel of a push-to-talk wireless device by; sending parameters comprising; (a) a maximum talk time (MIT) that represents an amount of time the push-to-talk wireless device can continuously occupy the transmit channel; and (b) a back offtime (BOT) representing a minimum time after the release of the transmit channel before the push-to-talk wireless device can again request the transmit channel; and granting the transmit channel; wherein upon the transmit channel being continuously occupied for the MIT, the transmit channel is automatically released thereby allowing another device to occupy the transmit channel. - View Dependent Claims (11, 12, 13)
