1. a TDD minizone sub-frame configuration coordination approach, is characterized in that, comprising:

  • Sub-frame configuration alteration of judgment is carried out to this base station cell in TDD base station cell, source, and when judgement carries out sub-frame configuration change for needs to this base station cell, sends sub-frame configuration change request to adjacent target TDD base station cell;

    Wherein, described sub-frame configuration changes the sub-frame configuration of carrying in request message and expecting active TDD base station cell, and one of following information or combination in any;

    The sub-frame configuration that TDD base station cell, source is current;

    The reason changing sub-frame configuration is expected in TDD base station cell, source;

    That TDD base station cell, source measures and between target TDD base station cell path loss;

    The target TDD base station cell downstream signal power that TDD base station cell, source receives;

    The downstream signal transmitting power of TDD base station cell, source;

    TDD base station cell, described source receives the described sub-frame configuration that whether accepts of replying described target TDD base station cell and changes the feedback information of asking, and according to described feedback information, this base station cell is carried out to the relative set of sub-frame configuration;

    Wherein, described feedback information comprises one of following information or combination in any;

    TDD base station cell, refusal source sub-frame configuration changes the reason of request;

    The sub-frame configuration mode of the TDD base station cell, source that target TDD base station cell can accept;

    The transmitting power of the TDD base station cell, source that target TDD base station cell can accept.
