Abstract
Methods and systems for reducing communication session establishment latency are introduced. In a wireless communication network, a radio access network (RAN) determines that a wireless communication device (WCD), such as a mobile phone, is attempting to establish a communication session. Based on the quality-of-service sensitivity of the communication session as well as recent reports of wireless coverage quality received from the WCD, the RAN selects an appropriate timeout value. This selected timeout value is used for a timer associated with a communication session establishment message transmitted by the RAN to the WCD. As a result, the RAN can retransmit the communication session establishment message rapidly in situations where the communication session establishment message is more likely to be lost.
