METHOD FOR FACILITATING A MOBILE STATION TO PERFORM A FAST HANDOFF
First Claim
1. A method for facilitating a mobile station to perform a fast handoff, comprising:
- obtaining a neighbor list, the neighbor list including a list of member base stations;
determining whether a member base station of the neighbor list is a successful target base station based on historical data;
if the member base station is not the successful target base station,scanning the member base station and measuring a signal quality associated with the member base station, andsending a measurement report for the member base station when the signal quality meets a standard signal quality threshold; and
if the member base station is the successful target base station,scanning the member base station and measuring the signal quality associated with the member base station, andsending the measurement report for the member base station when the signal quality meets a lower signal quality threshold, wherein the lower signal quality threshold is lower than the standard signal quality threshold.

Abstract
A method for facilitating a mobile station to perform a fast handoff in a wireless communication system allows a handoff procedure to be anticipated (by the mobile station, its serving base station, or both) based on historical information regarding prior successful handoff procedures. In operation, the mobile station receives a neighbor list from a serving base station and determines whether a member base station of the neighbor list is a successful target base station based on historical data. If the member base station is not a successful target base station, the mobile station scans the member base station, measures a signal quality associated with the member base station, and sends a measurement report for the member base station when the signal quality meets a standard signal quality threshold. If the member base station is a successful target base station, the mobile station sends the measurement report for the member base station when the measured signal quality meets a lower signal quality threshold.

14. A method of a base station for facilitating a mobile station to perform a fast handoff, comprising:
-
determining a high probability target base station with which the mobile station is most likely to perform handoff based on a historical data; requesting allocation of air interface resources at the high probability target base station to the mobile station, prior to the mobile station reporting reception of signals from the high probability target base station, to facilitate the mobile station to perform the fast handoff with the high probability target base station. - View Dependent Claims (15, 16, 17, 18, 19, 20)
