METHOD FOR SWITCHING AMONG WIRELESS ACCESS POINTS HAVING SELECTIVE PRE-AUTHENTICATION BEFORE ANTICIPATED WIRELESS ACCESS POINT BECOMES AN ACTUAL PRIMARY WIRELESS ACCESS POINT

摘要

PURPOSE: A selective pre-authentication to anticipated primary wireless access points is provided to reduce a latency during a wireless access point switching operation by performing pre-authentication. CONSTITUTION: A wireless device(220) facilitates a switching operation from a wireless access point(201 - 206) to another wireless access point. An application currently running on the wireless device is determined to have a low latency when switching from one wireless access to another wireless access. A communication is performed through a first wireless access point(205). A second wireless access point(204) is within a range and is determined to be potentially communicated with even though the wireless device is currently communicating with the first wireless access point. In response to the determination that the application has a low latency, before making the second wireless access point the first wireless access point, the wireless device directs to the second wireless access point to acquire an authenticated state with the second wireless access point.
