1. a base station controller, comprising:

  • Impel this base station controller to transfer signals to mobile radio station and make described mobile radio station in neighbor set, find a circuit that enough transmits Pilot Strength Measurement Message when strong pilot signal at described mobile radio station, wherein said neighbor set is not associated with activity collection pilot signal and Candidate Set pilot signal;

    WithImpel this base station controller to transfer signals to described mobile radio station and make described mobile radio station in periodic basis, produce the circuit of Pilot Strength Measurement Message,Wherein, in the time that the active concentrated number of sectors of primary channel exceedes the active maximum quantity of concentrating sector of complement channel, base station controller produces signal to mobile radio station so that it is transitioned into mobile radio station wherein and periodically transmits the cycle Pilot Strength Measurement Message transmission state of cycle Pilot Strength Measurement Message, andWherein, drop to while equaling the active maximum quantity of concentrating sector of complement channel in the active concentrated number of sectors of primary channel, base station controller produces a signal to mobile radio station so that it is transitioned into mobile radio station wherein and transmits according to specified requirements the interim Pilot Strength Measurement Message transmission state of cycle Pilot Strength Measurement Message temporarily.
