Abstract:
A mobile station that selects one of a plurality of base stations according to electric field strengths of signals transmitted on control channels corresponding to the plurality of base stations, and establishes first a link and then a call connection with the selected base station on a traffic channel that is assigned via a control channel corresponding to the selected base station,the mobile station comprising: a measuring means for measuring an electric field strength of a signal on the traffic channel when a link operation is performed to establish the link for the traffic channel; and a judging means for judging whether the link operation should be continued according to the measured electric field strength, wherein the measuring means measures the electric field strength by calculating an average of electric field strengths measured in a plurality of slots, and each of the electric field strengths comprises first and second signal levels, the first signal level being determined by a reception signal received from the selected base station, and the second signal level being a noise level and determined by no reception signal received from the selected base station.
