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