ABSTRACT:
In one illustrative example of the present application, a mobile communication device has one or more processors, a wireless transceiver adapted to provide communications through a wireless communication network, and a buffer memory for use in buffering a Push-To-Talk (PTT) communication from the mobile communication device. The one or more processors are operative to produce a mobile device indication message which indicates the mobile device's support for buffering of the PTT communication. 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 communication. 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.
