  • Patent number: 8824385
    Abstract: Provided are an LMA, a proxy router, and a management method for supporting NEMO in a PMIPv6 network. To support mobility in the PMIPv6 network for mobile nodes forming one node group within a mobile network, the proxy router for delivering signal and data between the mobile nodes and the PMIPv6 network delivers mobile home network prefixes allocated by the LMA of the PMIPv6 network to the mobile nodes. The LMA generates a group ID corresponding to the node group. Packet delivery costs due to an unnecessary tunnel may be reduced by grouping a plurality of mobile nodes constituting a mobile network, and using and managing flags and the same group ID.
