APPARATUS AND METHOD OF CONTROLLING SEAMLESS HANDOVER BETWEEN HETEROGENEOUS NETWORKS BASED ON IPV6 OVER IPV4 TUNNELING MECHANISM
摘要
The invention relates to a method and an apparatus for controlling seamless handover between heterogeneous networks based on IPv6 over IPv4 tunneling. When IPv6 service is provided using tunneling in an IPv4 based network environment, handover of a mobile terminal between different networks is achieved through switching of an active tunnel and a standby tunnel, and thus handover between different networks is facilitated and data loss is prevented to secure continuity of service provided to the mobile terminal even when the mobile terminal hands over to a heterogeneous network.
