Methods and apparatus for providing PTT data buffering support indications from mobile devices and PTT data buffering control by wireless networks |
摘要 |
In one illustrative example, a technique in a mobile communication device which is operative in a wireless communication network for Push-To-Talk (PTT) communications involves receiving, at the mobile communication device, presence information associated with at least one other mobile communication device, the presence information including at least one of a current availability indication or capability indication; and buffering a PTT communication prior to its transmission from the mobile communication device based on the presence information. The current availability or capability indication may be an automatic answering indication or a media capability indication, as examples.
