Router Selection Method, Home Agent Device, Mobile Router, and Mobile Network System
First Claim
1. A method of selecting a router in a mobile network system including a mobile network with a plurality of mobile routers and a terminal interconnected;
- and a home agent device managing a position at which the mobile network connects to an external network, comprising;
a step in which a mobile router or a terminal acquires policy information indicating a policy for selecting a mobile router, from a user;
a step in which the mobile router or the terminal informs a home agent device of the policy information;
a step in which the home agent device creates relay setting information according to the policy information informed, and informs the mobile router; and
a step in which the mobile router, when receiving a packet addressed to an external network, judges whether the mobile router relays the packet received, addressed to the external network, to the external network, or transfers the packet to an other mobile router, according to the relay setting information, and if transferring, determines a transfer destination.

Abstract
Any mobile router or terminal informs a home agent device of a policy of selecting a mobile router, entered by the user. Then, the home agent device creates relay setting information according to the policy information informed and the characteristic information of the mobile routers, and transmits the information to the mobile routers. This relay setting information is for judging whether a packet addressed to the external network, received by the mobile routers is relayed to the external network or transferred to the own network, and if transferring, for determining a transfer destination. Each of the mobile routers relays a received packet according to its relay setting information, thus implementing communication reflecting a user'"'"'s intention as needed.
