Method, system and apparatus for performing mobile internet protocol deregistering

摘要

A method, a system and an apparatus for performing mobile Internet protocol deregistering, includes that the network element in the ASN to which the terminal attaches detects whether the MS terminates unconventionally, and sends the message with the MS identifier of the MS which terminates unconventionally to the ASN GW/DP. The ASN GW/DP instructs the ASN GW/FA to release the link resource with the MS and release the link resource with the HA proving service for the MS.
