The invention discloses a method for improving call speed and call completion ratio of PHS mobile phone. The PHS mobile phone can first identify a special network condition in a network environment of only one or a few mezzo forte signal base station, and a plurality of weak signal base stations, then use a strategy of incomplete traversing for ignoring multitudinous weak signal base stations, namely, use collecting attempt selected a few base stations in a preset call timer duration, reduce selection range, shorten candidate base station list, avoid low successful probability for establishing link on the weak signal base station and long call time, and avoid conditions of failure for attempting establishing link caused by temporality over weight network load or short time trouble, accordingly, the PHS mobile phone can adapt the present network condition which can solve problem of low call completion ratio and long call completion time caused by the complex weak signal environment.
