How QChat Works

QChat enables communication to begin with a single press of the PTT button on the handset. A QChat call is formed by combining separate point-to-point connections between each IP endpoint at a managing entity known as the QChat Applications Server (QAS), deployed on the operator’s IP Wide Area Network (WAN).

Pressing the PTT button originates a call to the target QChat user and provides the originator with information indicating the availability (presence) of the target user. If the target user is available, the originator receives an immediate indication that the target user is available and the originator can begin speaking. The call originator’s voice is then sent through the operator’s network to the target’s handset. Initiating a call to a QChat user who is not available will simply result in a non-response tone rather than a busy signal or a voicemail.

The QChat client is the software that resides on the handset and serves as the platform for all QChat applications. QChat is written as a Binary Runtime Environment for Wireless™ (BREW™) application, and is thus available to be used by other applications. Users will have access to both QChat and BREW-enabled data applications as the BREW platform manages the intersection of data and telephony features on a mobile handset.
