The method includes: receiving infor mation about a processing type of registering a UE into a network, where the information is reported by the UE in the process of the registration; and identifying the processing type of the registration according to the information about the processing type. The system includes: a UE, adapted to report information about the processing type of registering the UE into a network in the process of the registration; and a net work, adapted to identify the processing type of the registra tion according to the received registration processing type information reported by the UE. 14 Claims, 18 Drawing Sheets NSN779-1001, Page 1
