When a mobile host or mobile router in nested mobile network is roaming in a domain with multiple mobility anchor points, if the mobile host or mobile router in the nested mobile network tree path chooses different mobility anchor points to derive its regional care-of address, routing sub-optimality may occur. To overcome such routing sub-optimality, this invention presents two main methods. The first method is where the mobile router detects that a downstream node in its tree path has derived a regional care-of address from another mobility anchor point, and will make appropriate on-demand duplicate registration at the other mobility anchorpoint. The second method is such that the mobile router informs its own mobility anchor point of other mobility anchor point addresses, so that the mobile router's mobility anchor point will pass the location entries of the mobile router to the other mobility anchor points. |
