Fig. 2 is a flowchart of another embodiment of the method for configuring a frequency point scrambling Code according to the present invention, and this embodiment takes a Femto base station in a Wideband Code Division Multiple Access (WCDMA) network as an example to introduce the method for configuring a frequency point scrambling Code according to the embodiment of the present invention.
As shown in fig. 2, this embodiment may include:
step 201, after the first Femto base station is powered on, entering a terminal mode, and performing measurement according to the configured frequency point list and scrambling code list to obtain a measurement report.
In this embodiment, the measurement report includes measurement information, location information, and priority information of the first Femto base station; the measurement information comprises received signal quality information of the frequency point obtained after the first Femto base station carries out measurement according to the configured frequency point list, and received signal quality information of the scrambling code obtained after the first Femto base station carries out measurement according to the configured scrambling code list.

Specifically, the format of the measurement report may be as shown in table 1.

In this embodiment, the priority information of the Femto base station may be preset, for example: a priority level may be set for a Femto base station when the Femto base station is purchased. The priority information of a Femto base station can be represented numerically, for example: the priority of the Femto base station can be represented by 1-10, and the higher the number is, the higher the priority of the Femto base station is.
