Abstract:
Methods and an apparatus are provided for providing handoff information to a candidate mobile node initially served on a first carrier. The candidate mobile node may inform a wireless-communication network that hard-handoff criteria are met for the first carrier. The network may identify a plurality of neighboring mobile nodes served on a second carrier and within a threshold distance of the candidate. The network may receive a measurement of forward-link signal quality of the second carrier from each neighboring mobile node. Using the received forward-link-signal-quality measurements, the network may estimate the forward-link signal quality of the second carrier at the location of the candidate mobile node. If that estimated forward-link signal quality exceeds a signal-quality threshold, the network may provide hard-handoff information about the second carrier to the candidate mobile node.
