  • Publication number: 20070054687
    Abstract: A push-to-talk data transmission device that creates and manages groups of participating terminals dynamically. A PoC data transmission device is deployed to support push-to-talk sessions in a prescribed area. This device has a data transmitter that broadcasts a group profile repetitively in the prescribed area. The group profile is a set of parameters that prompt terminals in the prescribed area to send back their respective unique identifiers to join a push-to-talk session. A counter in the PoC data transmission device counts the number of responses returned from the terminals, and the data transmitter broadcasts a new group profile if the number of responses has reached a predetermined threshold.
