1. A method, in a management device in wireless relay communication network, for reconstructing the network topology of multiple cells in the domination of said management device, wherein, the network topology of said multiple cells is reconstructed according to a traffic related information of said multiple cells, the method further comprising:

  • a. obtaining the traffic related information of each cell in said multiple cells respectively;

    b. judging whether the traffic related information of at least one cell in said multiple cells satisfies a predefined condition;

    c. performing load balancing among the multiple cells by reconstructing the network topology when the traffic related information of at least one cell in said multiple cells satisfies the predefined condition, wherein;

    c1. if the traffic related information of at least one cell in said multiple cells satisfies the predefined condition, determining to hand over at least one relay station or at least one relay station together with at least one mobile station in each of said at least one cell to a neighboring cell;

    c3. notifying respectively at least one relay station or at least one relay station together with at least one mobile station in each of said at least one cell to perform handover operation, or notifying a handover controlling device to which each of said at least one cell belongs, to indicate at least one relay station or at least one relay station together with at least one mobile station in the domination of said handover controlling device to perform handover operation, wherein, each notification comprises the handover related information of the neighboring cell to which each relay station or mobile station is going to be handed over.
