ACCESS MANAGEMENT METHOD, DEVICE AND SYSTEM

摘要

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. The technical scheme provided in the present application is applicable to an identification network, which implements accurate and high-efficient update of identity and location mapping table entries.
