FAST HANDOVER METHOD FOR PROXY MOBILE IPV6 NETWORK USING HIERARCHICAL STRUCTURE

摘要

The present invention relates to a fast handover method in piem IP V Six (PMIPv6) network, the fast handover method in a V Six piem IP network according to the invention, the step of configuring the IP piem V Six networks including the LMA and the LMA lower layer of the upper layer; Step of calculating the speed and direction of the MAG of the MN by using the signal strength information from the AP; MAG during handover of the MN is sending the information about the speed and direction of the MN to the LMA of the lower layer; And LMA in the lower layer is greater than the reference speed when the speed of the MN and the MN performs a handover has to be coupled to the LMA in the upper layer, the hand is less than a reference speed when the speed of the MN, the MN is to be connected to the LMA of the other lower layer performing an over; and include, LMA of the higher layer may be able to communicate at least one MAG and LMA, and one or more lower layers, LMA of the lower layer is able to communicate with the LMA and MAG one single upper layer which has a structure. ;
