Abstract: The present application discloses a DCN processing method for a PLMN that is applied to a network sharing scenario. An access feedback message of a network side is received, and selection assistance information of a DCN and an identifier of a PLMN that serves UE are obtained from the access feedback message, so as to know a PLMN that is actually accessed by the UE. A correspondence between the selection assistance information of the DCN and the identifier of the PLMN that serves the UE is stored. When the UE moves to coverage of the PLMN, a requested DCN to be accessed can be directly determined according to the correspondence, and a RAN node is requested to access the determined DCN. Therefore, a redirection process is reduced, and resource overheads are reduced.
