`Claim 35, wherein the second migration control
`unit further comprises detect means for detecting
`whether or not the packet transfer suppressing
`means in the first migration control means sup(cid:173)
`presses the transfer oft he packet, the first migra(cid:173)
`tion control means being attached to the network
`to which the mobile node migrates, and

`
`@ Migration communication control device.
`@ Disclosed is a migration communication con(cid:173)
`trol device constructed to control a continuous
`communication between a mobile node and a
`node unaffected the mobile node's migration.
`The migration communication control device
`comprises a first migration control unit, a sec(cid:173)
`ond migration control unit on the mobile node,
`and a third migration control unit on the partner
`node. The first migration control unit comprises
`a packet transfer unit and an address post unit.
`The packet
`transfer unit receives a packet
`which was destined for an outdated address of
`the mobile node, generates a conversion packet
`which holds an updated address instead of the
`outdated address. and then transmits the con(cid:173)
`version packet, while an address post unit
`transmits an address post message which indi(cid:173)
`cates the updated address to the third migration
`control unit. The second migration control unit
`comprises a migration post unit and a packet
`resumption unit. The migration post unit trans(cid:173)
`mits to
`the first migration control unit a mi(cid:173)
`gration post message which
`indicates
`the
`the mobile node mi(cid:173)
`updated address when
`grates to another network while a packet re(cid:173)
`sumption unit receives
`the conversion packet
`from both the first migration control unit and
`the third- migration control unit and resumes an
`original' packet from the conversion packet. The
`third migration control unit comprises a packet
`conversion unit which converts a destination
`address of a packet into the updated address,
`then transmits it to the mobile node.
