ABSTRACT:
In one illustrative example of the present disclosure, a mobile communication device has one or more processors and a wireless transceiver adapted to provide communications through a wireless communication network. The one or more processors are operative to produce a mobile device indication message which indicates whether the mobile device supports buffering of Push-To-Talk (PTT) communications from the mobile device. This message is transmitted by the wireless transceiver to a PTT service entity through the wireless network. The one or more processors may be further operative to receive, from the PTT service entity through the wireless network, a network indication message which instructs the mobile device whether to use buffering for the PTT communications from the mobile device (assuming a buffer memory for PTT buffering is available in the mobile device). The mobile device may use the buffer memory for the buffering of the PTT communication based on the network indication message from the PTT service entity.
