The 3rd determines submodule, the frequency and the scrambler of received signal quality optimum are all identical in the frequency that is used for the metrical information received signal quality optimum that reports when described first femto base station and scrambler and the metrical information that second femto base station reports, and according to the positional information of described first femto base station and the positional information of described second femto base station, when determining that distance between described first femto base station and described second femto base station is less than or equal to default distance threshold, determine the frequency and the scrambler of described first femto base station according to the precedence information of the precedence information of described first femto base station and described second femto base station.
6. center according to claim 5 arbitration node, it is characterized in that, the described the 3rd determines that submodule specifically is used for when the priority of described first femto base station is higher than the priority of described second femto base station, determines that the frequency of described first femto base station and scrambler are the frequency and the scrambler of received signal quality optimum in the metrical information that reports of described first femto base station; Perhaps, the described the 3rd determines that submodule specifically is used for when the priority of described first femto base station is lower than the priority of described second femto base station, determines that the frequency of described first femto base station and scrambler are the frequency and the scrambler of received signal quality suboptimum in the metrical information that reports of described first femto base station.
7. a frequency point scrambling code configuration-system is characterized in that, comprising:
Femto base station is used for reporting measurement reports, and described measurement report comprises metrical information, positional information and the precedence information of described femto base station; Described metrical information comprises the received signal quality information of the frequency that obtains after described femto base station is measured according to the frequency tabulation of configuration, and described femto base station is measured the received signal quality information of the scrambler of back acquisition according to the scrambler tabulation of configuration;
The center arbitration node is used to receive the measurement report that described femto base station reports, and determines the frequency and the scrambler of described femto base station according to described metrical information, positional information and precedence information.
