Abstract: The present invention relates to a handover method of a mobile IPv6 communication network capable of reducing the handover interrupt time, the packet loss rate, and the load of the home agent. The mobile station is a single or a multimode physical access terminal, and monitors a link situation to obtain a network handover initiation. After obtaining initiation information, the mobile station sends handover information including link information of a new access router to a current access router and the current access router returns network information of the new access router, and the mobile station starts a network layer handover of the mobile IPv6 before the link layer handover. Data sent from the communication end to the mobile station is directly sent to a new care-of address of the mobile station. In order to reduce the packet loss, the new access router stores data sent to the mobile station before the mobile station and the new access router establish their connection.
