摘要:
A method of handoff utilizing a combined signal quality measurement to trigger or initiate a handoff of a mobile station to a plurality of neighbor base stations, wherein the combined signal quality measurement corresponds to a summation of signal quality measurements associated with the plurality of neighbor base stations. The handoff is triggered when the combined signal quality measurement is greater than a handoff threshold. By using the combined signal quality measurement instead of a signal quality measurement of an individual neighbor base station, handoffs can be triggered earlier along a boundary shared by neighbor cells, thereby reducing interference associated with later triggered handoffs. When triggered, the mobile station is handed off to a plurality of neighbor base stations allowing the mobile station to establish simultaneous communication links with two or more neighbor base station. This increases the chance that at least one of the communication links or the combination thereof is a strong communication link, thereby improving the reliability and success rate of handoffs.
