Ericsson, Nokia and Siemens today announced a joint effort to define specifications for an open standard for direct-call push-to-talk (PTT) service over GPRS. Initial trials are expected to begin in the second half of 2003. The specifications, which will be designed to work over GPRS, EDGE, and WCDMA, will be submitted to relevant industry bodies for standardization. AT&T Wireless and Cingular both announced support for the initiative.
