Transition &4&%56 models the event of resetting the
forwarding chain of an MN during a location update, which
involves updating the MN’s location information in the
location database, and sending a location update message to
each active intranet correspondence node (CN) of the MN.
The signaling cost thus consists of two parts. The first part is
for the new MAG to inform the LMA to update the MN’s
location information in the location database, i.e., 7(. The
second part is for the new MAG to inform the active intranet
CNs of the MN, i.e., 3. Thus, the transition rate 8/9/.:
is
8/9/.: 1
