Local mobility anchor, proxy router, and management method for supporting network mobility in proxy mobile IPv6 network

摘要

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.

1. A local mobility anchor (LMA) comprising:
a LMA that allocates mobile home network prefixes for address creation in a proxy mobile internet protocol version 6 (PMIPv6) network to mobile nodes forming one node group within the PMIPv6 network, and allocates a unique group identifier (GID) to a proxy router which delivers signal between the node group and the PMIPv6 network, wherein the GID is common to the proxy router and the mobile nodes forming one node group managed by the proxy router, and wherein the proxy router delivers information regarding attachment of each of mobile nodes forming one node group within a mobile network and leaving from the node group, to a proxy mobile Internet protocol version 6 (PMIPv6) network.
