Patent ID: 8000313

Claim:
A method for reducing communication session establishment latency, wherein a radio access network (RAN) defines at least one wireless coverage area, wherein a wireless communication device (WCD) is served by the at least one wireless coverage area, wherein the WCD, from time to time, transmits to the RAN a wireless coverage quality value as measured at the WCD, wherein the RAN stores a timer to use with a message that the RAN transmits to the WCD during establishment of a communication session, and wherein the timer is configured with a pre-determined default value, the method comprising: the RAN maintaining a threshold wireless coverage quality value, the RAN receiving an indication that the WCD is attempting to establish the communication session; responsive to receiving the indication, the RAN determining that (i) the communication session is quality-of-service sensitive, and (ii) a recent wireless coverage quality value received from the WCD is less than that of the threshold wireless coverage quality value; responsive to the determining, the RAN configuring the timer with a second value, wherein the second value is less than the pre-determined default value; and during establishment of the communication session to the WCD, the RAN (i) transmitting the message to the WCD, (ii) waiting a period of time according to the timer, (iii) determining that the RAN has not received a response to the message, and (iv) again transmitting the message to the WCD.
