1. A coordinated processing method for northbound data configuration and self-organized network (SON) configuration, comprising: a northbound configuration module receiving a data configuration request sent by a superior network management, and sending the data configuration request to a conflict resolution module; an SON function management module receiving a parameter optimization request sent by an SON function module, and sending the parameter optimization request to the conflict resolution module; the conflict resolution module receiving the data configuration request sent by the northbound configuration module and the parameter optimization request sent by the SON function management module, and if judging that a parameter requested by the northbound configuration module to be configured conflicts with a parameter requested by the SON function management module to be configured, then sending a conflict judgment message indicating conflict to the northbound configuration module and the SON function management module respectively; after receiving the conflict judgment message indicating conflict sent by the conflict resolution module, the northbound configuration module performing data configuration in the data configuration request and reporting conflict information to the superior network management; and after receiving the conflict judgment message indicating conflict sent by the conflict resolution module, the SON function management module notifying the SON function module to perform parameter rollback and/or end a current self-optimization procedure.
