A communication system 32 is provided with access routers 14 , a location information management server 20 , and a route optimization server 18 . The route optimization server 18 receives a BU message from a Mobile-IP terminal 12 A and receives location information of a connected access router 14 A from the location information management server 20 . Then the route optimization server 18 transmits the BU message to the connected access router 14 A, based on the received location information of the connected access router 14 A, whereby the connected access router 14 A to which the communication terminal 12 is connected is notified of route optimization information. This permits the connected access router 14 A to relay a packet transmitted and received between the Mobile-IP terminal 12 A and the communication terminal 12 , through an optimal route.
