        4. (no reply)
            # Wait during a maximum of 3 seconds(RFC2461).
        5. Receive Binding Update. (NUTX -> HA0)
        6. Send Binding Acknowledgement. (HA0 -> NUTX)
            # The Status field is set to the value(=127) except 0 and 1.
        7. (wait)
            # Wait during enough retransmission timer.

11.7.3 Receiving Binding Acknowledgements
                    
(snip)
                    
   o  If the Status field indicates that the Binding Update was accepted
      (the Status field is less than 128), then the mobile node MUST
      update the corresponding entry in its Binding Update List to
      indicate that the Binding Update has been acknowledged; the mobile
      node MUST then stop retransmitting the Binding Update.  In
      addition, if the value specified in the Lifetime field in the
      Binding Acknowledgement is less than the Lifetime value sent in
      the Binding Update being acknowledged, then the mobile node MUST
      subtract the difference between these two Lifetime values from the
      remaining lifetime for the binding as maintained in the
      corresponding Binding Update List entry (with a minimum value for
      the Binding Update List entry lifetime of 0).  That is, if the
      Lifetime value sent in the Binding Update was L_update, the
      Lifetime value received in the Binding Acknowledgement was L_ack,
      and the current remaining lifetime of the Binding Update List
      entry is L_remain, then the new value for the remaining lifetime
      of the Binding Update List entry should be
