PATH CONTROL METHOD AND HOME AGENT

摘要

A mobile network system includes a mobile network having a mobile router and a terminal connected to each other and a home agent. When the mobile router is connected to an external network, path information on its mobile network is reported to the home agent. Upon reception of the path information, the home agent asks the mobile router in the home network whether it is connected to the reported mobile network. If no mobile router is connected, the home agent advertises the information on the path to the mobile network. Thus, the home agent can rapidly switch to an optimal path to the external network.
