    摘要： A method and apparatus for facilitating handoff operations in a wireless communication device is provided. The method may comprise receiving, by a wireless communication device, a plurality of pilot signals, wherein the plurality of pilot signals includes an active pilot signal and one or more candidate pilot signals, selecting at least one nominal active pilot signal strength value for comparison with the active pilot signal, classifying the one or more candidate pilot signals into a respective one of a plurality of tiers based on a handoff factor corresponding to the at least one candidate pilot signal, wherein the plurality of tiers are divided according to one or more handoff factors, and selecting at least one threshold handoff value for each of the plurality of tiers, wherein the at least one threshold handoff value partly depends on one of the at least one nominal active pilot signal strength values.

    摘要： More seamless handoff between access networks is achieved by saving session information for each access network upon being handed off from the access network and invoking the saved session information upon being handed back to the access network. An access terminal establishes a first session with a first access network, which may entail performing QoS negotiation with the first access network and setting up packet filters at a packet data gateway. The access terminal exchanges data with the first access network in accordance with the configuration of the first session. The access terminal saves the first session configuration after being handed off to a second access network, establishes a second session with the second access network, and exchanges data with the second access network in accordance with the configuration of the second session. The access terminal uses the saved first session configuration upon being handed back to the first access network.
