An access management method, device and system are disclosed. It relates to the field of communication; and the problem that the existing update mechanism of an AID and RID mapping relationship table has a low reliability and influences the network working efficiency is solved. The method includes: when detecting that an MN accessing an ASR is offline, the ASR querying a local AID and Routing Identity RID mapping table, and determining a correspondent node of the offline MN; and the ASR sending a mapping table entry update message to an ILR and an ISR and an ASR where the correspondent node is located, and setting an RID in a mapping table entry corresponding to the MN to be NULL, which represents that the MN does not access the ASR currently.
