Patent ID: 8180386

Claim:
A system for promoting push-to-talk communication, comprising: a processor; and an exchange component, when executed by the processor, that initiates a push-to-talk contact identifier exchange to enable push-to-talk communications in response to identifying a full-duplex voice call between a first mobile device and a second mobile device, wherein to perform the push-to-talk contact identifier exchange, the exchange component, determines whether the first mobile device selects to share a first push-to-talk contact identifier associated with the first mobile device with other mobile devices, determines whether the second mobile device selects to share a second push-to-talk contact identifier associated with the second mobile device with other mobile devices in response to a determination that the first mobile device selects to share the first push-to-talk contact identifier with other mobile devices, communicates the second push-to-talk contact identifier to the first mobile device in response to a determination that the second mobile device selects to share the second push-to-talk contact identifier with other mobile devices, and communicates the first push-to-talk contact identifier to the second mobile device in response to communicating the second push-to-talk contact identifier to the first mobile device.
