MEASUREMENTS ON LTE FOR CSFB RAT PRIORITIZATION

摘要

The present invention relates to a method at a base station (10) of changing Radio Access Technology (RAT) of a mobile terminal (11) in a communications network, and a base station performing the method. The method according to an embodiment of the present invention comprises determining (S101) that a change is to be made from a serving RAT to a first target RAT, estimating (S102) a quality measure of the first target RAT based on a quality measure of the serving RAT, and instructing (S103) the mobile terminal to change to the first target RAT if the estimated signal quality measure of the first target RAT exceeds a quality threshold value.
