Abstract
Rerouting of packet exchanges by a mobile terminal is controlled so as to be optimized on a real time basis to prevent network resources from being wasted by redundant routing. In an initial state a route of data from a mobile communication terminal M to a CN, which is a communication partner, is a route R. Then, an access router (AR)acquires the number of hops of data received from the CNby the mobile communication terminal M. As the mobile communication terminal M now performs a handover to under the command of the AR, the route will change to a route R. Then the ARdetects that the route becomes redundant by the fact that the number of hops acquired after the shift is greater than the pre-shift number of hops received from the AR, and invokes control to reroute to a route R, which provides the optimal routing.
