METHOD FOR AUTOMATIC RELEASE OF PUSH - TO - TALK

by Senaka Balasuriya

ABSTRACT

This presents a method that enables a dispatch capable client to automatically release Push-to- Talk (PTT), where an intelligent algorithm computes the PTT release time based on criteria such as speechinactivity and statistics from past conversations.

BACKGROUND

In current dispatch systems, a user has to press the PTT button on a communication device in order to be authorized to speak. When the PTT button is pressed, the device communicates with a controller (j.e. a DAP in iDEN/Nextel systems) to obtain authorization to talk. When the user has finished speaking, he releases the PTT button to end talking.

This allows another party to obtain PTT or allows the call to end if nobody pushes PTT again.

As traditional telephony continues to converge with the Internet, dispatch is proliferating onto the Internet as well. For example, Yahoo! and hearnle.com already offer "voice chat" , an Internet dispatch service. In traditional dispatch, the user holds the phone (i.e. iDEN phone) in his hand while talking. Since he is already holding the phone, pushing and releasing a button is relatively easy. On the other hand, keeping a button pushed or remembering to release PTT after talking is difficult in computer environments and is not intuitive to the Internet user. Therefore, a different method to enable releasing of PIT is required.

INVENTION

The present invention enables a dispatch capable client to automatically release PTT after a period of time. This period of time is computed by an intelligent algorithm on the device that detects speech-inactivity and other factors such as a user's past conversation time and general user conversa-

tion times. Because the prediction mechanism employs continuous learning, the invention should perform well after the initial learning period.

Furthermore, this concept introduces a button through which the user can extend his talk time by a specified period of time.
