The present disclosure provides a method for processing user contract data, UDM-Proxy, system and storage medium, wherein the method comprises: the UDM-Proxy set in the 5G private network receives a first data configuration request, generates a second data configuration request and sends it to the IWF, so that the IWF forwards the second data configuration request to the operation management system for corresponding processing; the UDM-Proxy receives the user contract data sent by the IWF and stores it; wherein the UDR set in the 5G public network sends the user contract data to the IWF. The method, UDM-Proxy, system and storage medium of the present disclosure use UDM-Proxy to replace the UDM in the 5G private network, which can achieve the user data not leaving a specific area while meeting the demand for intensive management of user data, and can ensure the operator's supervision of user contract data; by using the IWF as an intermediate node to forward requests, the operator's network security can be guaranteed.
