Abstract
A half-duplex communication system is embodied in a push-to-talk cellular system such as a GPRS system. The system includes two or more terminals (A,B,C) one or more of which can operate in a hands-free mode. When in hands-free mode, a terminal (A) is offered the right-to-speak by a controller (A,A,A,A) within the system without the need for a talk request from a user. This allows a hands-free user to participate safely in a communications session.
