Method for push-to-talk pre-emption
First Claim
1. A method for providing push-to-talk (PTT) pre-emption comprising:
- establishing a PTT call between a subscriber device and an application server which implements a voice-enabled application over a wireless network;
granting a PTT floor to the application server to provide an application voice/data stream to the subscriber device;
detecting a pre-emption request by the subscriber device to interrupt the application voice/data stream;
revoking the PTT floor from the application server and interrupting the application voice/data stream in response to the pre-emption request; and
granting the PTT floor to the subscriber device upon interruption of the application voice/data stream in response to the pre-emption request.

Abstract
Push-to-talk private call pre-emption may be applied in an application-to-person context or on a person-to-person context. A PTT subscriber may send a PTT server a pre-emption request indicating a desire to interrupt the application voice stream or another PTT subscriber, respectively. In an application-to-person context, the PTT server may revoke the floor from the application server and grant the floor to the requesting device. In a person-to-person context, the PTT server may send the other PTT subscriber a floor release request. Once the subscriber with the PTT floor releases it in response to the floor release request, the PTT server will be able to send an open floor signal back to the requesting subscriber.
