And step 604, the operation maintenance client updates the database according to the processing result and triggers PCI self-configuration.
In step 605, the operation and maintenance client sends the configuration information to the OAM entity.
Generally, the configuration information includes an identification of the base station, parameter information of the base station, and the like.
In step 606, after receiving the configuration information, the oam entity determines the 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; the base station to be configured is a GSM/SCDMA base station, and the SON entity is a 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 sends the configuration information to the base station corresponding to the TD-LTE.
