Patent ID: 8688843

Claim:
A method of setting-up a communication session within a wireless communications system, comprising: receiving, from a session originator, a request to initiate the communication session with a set of session targets; transmitting one or more call announcement messages for announcing the communication session to the set of session targets; determining information associated with a probability that the set of session targets will fail to accept the announced communication session; and selectively granting a floor of the communication session to the session originator based on the determined information: wherein the selectively granting step selects between (i) preemptively granting the floor to the session originator before an affirmative acceptance of the announced communication session arrives from one or more of the set of session targets and (ii) waiting until after the affirmative acceptance of the announced communication session arrives from the one or more of the set of session targets before granting the floor to the session originator.
