FIELD: radio engineering, communication.
SUBSTANCE: method comprises: an ASR requesting a mapping table containing at the local level an AID and a RID, when it is detected that a MN, accessing the ASR, is in offline mode; determining a correspondent node of the offline MN; the ASR sending a mapping table entry update message to an ILR, an ISR and an ASR where the correspondent node is located; and setting a RID corresponding to the MN to be NULL, which indicates that the MN does not access the ASR currently.
EFFECT: high accuracy and efficiency of updating mapping table entries containing access and routing identifiers.
