1. One kind use CDMA modulation mobile radio station from and current wireless cellular system base station between forward direction and backward chaining switches to and new base station between forward direction and the method for backward chaining, may further comprise the steps:

  • Running frequency according to new running frequency handover of mobile stations;

    On new running frequency, set up new forward direction and the backward chaining that is derived from the mobile radio station end before during transition finishing with the starting spreading factor;

    After during transition finishing, on the new url of setting up, communicate by letter with final spreading factor;

    Wherein, the starting spreading factor is the twice of final spreading factor at least.
