发明名称 System and method for transmitting tones in a push-to-talk (PTT) system
摘要 Systems and methods for allowing transmission of tones by a push-to-talk (PTT) communication station are provided. The communication station can decouple the PTT button of the PTT communication station, allowing the transmission of the tones without actuating the PTT button. The decoupling can be performed in response to receipt of an unsolicited floor grant message. The communication station can also receive an input selection and automatically transmit a floor request message, a tone corresponding to the input selection and a floor release message.
