Abstract:
An edge router 12 sends a router advertisement to wireless terminals 11 to notify the wireless terminals 11 of the hop limit. Each wireless terminals 11 stores the notified hop limit in the hop limit field of an IPv6 packet. The edge router 12 stores the maximum number of hops in the user's home system 1 and the maximum number of hops in the IP network NW. When receiving a communication packet sent from the user's home system 1 to the IP network NW, the edge router 12 sets the hop limit in the communication packet to the maximum number of hops in the IP network NW. When receiving a communication packet sent from the IP network NW to the user's home system 1, the edge router 12 sets the hop limit in the communication packet to the maximum number of hops in the user's home system 1.
