  • Method and system for originating and receiving emergency push-to-talk calls
    Patent number: 8878889
    Abstract: A wireless communication device (WCD) that is configured to originate and receive push-to-talk (PTT) calls may be identified by a standard identifier in standard PTT calls and may be identified by an emergency identifier in emergency PTT calls. The WCD may be configured to recognize an emergency trigger and, in response to the emergency trigger, originate an outgoing emergency PTT call, using the emergency identifier. If, while engaged in a standard PTT call, the WCD receives an incoming emergency PTT call that includes the WCD's emergency identifier, the emergency PTT call may preempt the standard PTT call. For example, the WCD may convey audio from the emergency PTT call to a speaker or other audio output interface, instead of audio from the standard PTT call. The WCD may also release the standard PTT call.
