发明名称 Methods and apparatus for using VPN gateway acting as Mobile IP Foreign Agent FA for mobile node
摘要 A communication method and apparatus using the IP address of a gateway (105) for an MN (107) in a VPN (101) are provided. When the MN (107) is to access the VPN (101), the gateway (105) acting as FA in the VPN performs a Mobile IP registration on behalf of the MN (107) and is allocated a HoA for the MN (107) from an HA (103). Therefore, the number of addresses required for the Mobile IP registration of the MN (107) is reduced and overlap between an IP-in-IP tunnel for Mobile Internet and an IPsec tunnel for the VPN is avoided. As a result, packet transmission overhead is reduced.
