Abstract:
1. A method for use in Push-To-Talk (PTT) voice communications for a mobile station, the method comprising the steps of: identifying a user actuation of a PTT switch for initiating a PTT voice communication through a wireless communication network; in response to identifying the user actuation of the PTT switch: wherein an input pointer is used to identify a next memory location for storing voice data and an output pointer is used to identify a next memory location for retrieving and transmitting the voice data; identifying a user release of the PTT switch; storing an end marker for a memory location associated with the input pointer in response to identifying the user release of the PTT switch, the end marker being used to identify an end of the PTT voice communication; after identifying the user release of the PTT switch, continuing transmission of the voice data from the memory as the output pointer approaches the end marker; and if a subsequent user actuation of the PTT switch is identified during the continued transmission of the voice data front the memory: storing a pause marker in place of the end marker and causing a transmission of silent data when the output pointer reaches the pause marker, for thereby producing a silent pause in between the PTT voice communication and a subsequent PTT voice communication associated with the subsequent user actuation of the PTT switch.
