Abstract:
Methods and systems for providing fast handoff in WLAN-like communications system construct a caching candidate set based upon a weighted handoff tendency coefficient. The weighted handoff tendency coefficient is based upon the handoff matrix and the weighting factor. The handoff matrix is an adaptive two-dimensional array that provides a list of nearby access points relative to a mobile station and the weighting factor is a value that prioritizes the nearby access points based upon a signal quality indication. A home access point, once it is triggered to initialize proactive caching, provides the caching candidate set with registration data of the mobile station before a transfer of a connection between the home access point and one of the access points on the caching candidate set.
