ABSTRACT:
An apparatus, system, computer-readable medium, and method to facilitate quick transition of communications of a mobile station between network stations of a radio communication system, such as a WLAN operable to a variant of an IEEE 802 operating specification, is provided. Implementations of embodiments described herein reduce the transition duration by a pre-keying mechanism that performs authentication procedures prior to commencement of reassociation procedures. In other embodiments, a mobile station is allowed to select whether to perform pre-keying processes over an air interface with a target transition access point or whether to perform the pre-keying processes over a distribution system.
