Method and System for Roaming Based on Range Differentials

원문 (중국어)

A method in a communications device includes: establishing a connection with a base station; when an attribute of the connection satisfies an auxiliary trigger, obtaining: a first initial distance estimate to the base station; a second initial distance estimate to a candidate base station; determining: a first score for the base station, based on the first initial distance estimate; and a second score for the candidate base station, based on the second initial distance estimate; and when the attribute of the connection satisfies a roaming trigger, subsequent to satisfying the auxiliary trigger, selecting a connection target from the base station and the candidate base station, based on the first score and the second score.
