Generally, the configuration information includes an identifier of the base station, parameter information of the base station, and the like.
Step 502, after receiving the configuration information, the OAM entity determines an SON entity corresponding to the communication system of the base station to be configured. For example, if the base station to be configured is a TD-LTE base station, the SON entity is a SON entity corresponding to the TD-LTE; if the base station to be configured is an SCDMA base station, the SON entity is an SON entity corresponding to the SCDMA.
In step 503a, if the base station to be configured is a TD-LTE base station, the OAM sends the configuration information to the SON entity corresponding to the TD-LTE.
In step 504a, after receiving the configuration information, the SON entity corresponding to the TD-LTE transmits the configuration information to the base station corresponding to the TD-LTE.

Generally, the configuration information includes an identifier of the base station, parameter information of the base station, and the like.
Step 606, after receiving the configuration information, the OAM entity determines an SON entity corresponding to the communication system of the base station to be configured. For example, if the base station to be configured is a TD-LTE base station, the SON entity is a SON entity corresponding to the TD-LTE; and if the base station to be configured is a GSM/SCDMA base station, the SON entity is the SON entity corresponding to the GSM/SCDMA.
In step 607a, if the base station to be configured is a TD-LTE base station, the OAM sends the configuration information to the SON entity corresponding to the TD-LTE.
In step 608a, after receiving the configuration information, the SON entity corresponding to the TD-LTE transmits the configuration information to the base station corresponding to the TD-LTE.
Step 607b, if the base station to be configured is a GSM/SCDMA base station, the OAM sends the configuration information to the SON entity corresponding to GSM/SCDMA.
