The method includes: receiving a BU message from a MN, and judging whether the home address of the MN is involved in a safety union list in which the home address of the MN involved can not be used by other MNs. If the home address of the MN is involved in the safety union list, sending a BA message that involves a binding complete information to the MN, and buffering the binding of the home address and the current CoA of the MN. Advantages of the invention: decreasing the time of registration to the HA , preventing the registration to the HA from suffering DOS attacking and packet discarding and connection interrupting, which is caused by time delay of the registration.
