Abstract:
A system and method for transmitting alert tone information among communicating wireless devices to identify a speaker in a push-to-talk system. A predefined set of alert tones is stored in a wireless device, and when a user presses a push-to-talk button on the wireless device, the wireless device displays a list of predefined alert tones to the user to select. After the user selects an alert tone, the wireless device transmits an alert tone code associated with the selected alert tone to a server for relaying to every wireless device in a push-to-talk communication group. When a receiving wireless device receives the alert tone code, it retrieves an alert tone corresponding to the alert tone code from the predefined set and plays the alert tone to the user of the wireless device.
