Abstract

The floor in a network-based instant connect communication session is managed such that a mobile device user can cause voice data to be transmitted to a remote party without the remote party giving consent to relinquishing the floor. After the network-based instant connect communication session is established, and as the remote party holds the floor, the mobile device user presses a talk button on the mobile device or otherwise provides input. The input causes the network-based instant connect communication session to transition from the original half-duplex communication to full-duplex communication. The mobile device user can then cause voice data to be sent to the remote device. In this manner, the mobile device user can interrupt or spontaneously respond to the remote party without waiting for the remote party to relinquish the floor. This facilitates comfortable two-way communication in a network-based instant connect communication session.
