buffering or refraining from buffering a PTT communication prior to its transmission from the mobile communication device based on the presence information;
wherein the PTT communication is buffered when the at least one of the current availability indication and the capability indication has a first setting, and is refrained from being buffered when the at least one of the current availability indication and the capability indication has a second setting.
2. The method of claim 1 , wherein the at least one of the current availability indication and the capability indication is a current availability indication of the at least one other mobile communication device.
3. The method of claim 1 , wherein the at least one of the current availability indication and the capability indication is a capability indication of the at least one other mobile communication device.
4. The method of claim 1 , wherein the at least one of the current availability indication and the capability indication comprises a manually-set availability indication of the at least one other mobile communication device.
5. The method of claim 1 , wherein the at least one of the current availability indication and the capability indication comprises an automatic answering indication of the at least one other mobile communication device.
6. The method of claim 1 , wherein the at least one of the current availability indication and the capability indication comprises a media capability indication of the at least one other mobile communication device.
7. The method of claim 1 , wherein the mobile communication device includes a buffer and a PTT switch, and the buffering of the PTT communication further comprises:
identifying an actuation of the PTT switch for initiating the PTT communication;
in response to identifying the actuation of the PTT switch:
saving, in the buffer, digital data corresponding to input signals at the mobile communication device;
making a request for the PTT communication via the wireless communication network;
identifying an indication to transmit the PTT communication; and
after identifying the indication to transmit the PTT communication, retrieving the digital data from the buffer and transmitting the digital data to the wireless communication network for the PTT communication.
8. The method of claim 1 , which is embodied as computer instructions stored in a non-transitory storage medium which are executable by one or more processors of the mobile communication device.
9. A mobile communication device, comprising:
one or more processors;
a wireless transceiver coupled to the one or more processors, the wireless transceiver being adapted to provide communications via a the wireless communication network;
the one or more processors being operative to:
receive, via the wireless transceiver, presence information associated with at least one other mobile communication device, the presence information including at least one of a current availability indication and a capability indication; and
buffer or refrain from buffering a PTT communication prior to its transmission from the mobile communication device based on the presence information;
wherein the PTT communication is buffered when the at least one of the current availability indication and the capability indication has a first setting, and is refrained from being buffered when the at least one of the current availability indication and the capability indication has a second setting.
10. The mobile communication device of claim 9 , wherein the at least one of the current availability indication and the capability indication comprises a current availability indication of the at least one other mobile communication device.
11. The mobile communication device of claim 9 , wherein the at least one of the current availability indication and the capability indication comprises a capability indication of the at least one other mobile communication device.
12. The mobile communication device of claim 9 , wherein the at least one of the current availability indication and the capability indication comprises a manually-set availability indication of the at least one other mobile communication device.
13. The mobile communication device of claim 9 , wherein the at least one of the current availability indication and the capability indication comprises an automatic answering indication of the at least one other mobile communication device.
14. The mobile communication device of claim 9 , wherein the at least one of the current availability indication and the capability indication comprises a media capability indication of the at least one other mobile communication device.
15. A method in a Push-To-Talk (PTT) service entity for use in facilitating a PTT communication session delivered via a wireless communication network, the method comprising:
sending, to a mobile communication device in the wireless communication network, presence information of at least one other mobile communication device, the presence information including at least one of a current availability indication and a capability indication; and
receiving a PTT communication from the mobile communication device;
wherein the PTT communication is buffered at the mobile communication device prior to its transmission when the at least one of the current availability indication and the capability indication has a first setting, and not buffered at the mobile communication device prior to its transmission when the at least one of the current availability indication and the capability indication has a second setting.
16. The method of claim 15 , wherein the at least one of the current availability indication and the capability indication comprises a current availability indication of the at least one other mobile communication device.
17. The method of claim 15 , wherein the at least one of the current availability indication and the capability indication comprises a capability indication of the at least one other mobile communication device.
18. The method of claim 15 , wherein the at least one of the current availability indication and the capability indication comprises a manually-set availability indication of the at least one other mobile communication device.
19. The method of claim 15 , wherein the at least one of the current availability indication and the capability indication comprises an automatic answering indication of the at least one other mobile communication device.
20. The method of claim 15 , wherein the at least one of the current availability indication and the capability indication comprises a media capability indication of the at least one other mobile communication device.
21. A Push-To-Talk (PTT) service entity for use in facilitating a PTT communication session delivered via a wireless communication network, the PTT service entity being configured to send, to a mobile communication device in the wireless communication network, presence information of at least one other mobile communication device, the presence information including at least one of a current availability indication and a capability indication of the at least one other mobile communication device; and receive a PTT communication from the mobile communication device; wherein the PTT communication is buffered at the mobile communication device prior to its transmission when the at least one of the current availability indication and the capability indication has a first setting, and not buffered at the mobile communication device prior to its transmission when the at least one of the current availability indication and the capability indication has a second setting.
