- the address information selected by the address selecting means 53 is provided by the instruction from the address selecting means 53.
- the above-mentioned address information provided to MN41 is deleted from the table.
- the table of the pAR address information storage means 51 holds a small number of unique nCoAs for each of the access routers that are geographically neighboring! /.
- This unique nCoA is, for example, an address confirmed to be unique by DAD (Duplicate Address Detection) processing.
- the above-mentioned geographically neighboring access router refers to another access router that manages a subnet adjacent to a certain pAR subnet (neighboring subnet), that is, a handover was performed from the MN41 power AR subnet. Access router that can be the next connection destination in such a case. The access router that may be the next connection destination after this handover is sometimes called a potential nAR (potential nAR).
- the adjacent subnets of the AR 21 subnet 71 are the subnets.
- the address information storage means 51 of AR21 stores address information usable in the respective subnets 72-74 of AR22-AR24.
- the pAR does not necessarily need to store address information that can be used in all adjacent subnets! Even if only the address information that can be used in specific adjacent subnets is stored, it can be used. Good.
- the ARs that are geographically neighboring are as follows: MN41 connected to pAR It can be used. These addresses can be obtained by direct request by the pAR for all possible nARs (ARs that can be nARs).
- the nAR composes the nCoA according to the direct requirements of the pAR.
- the nCoA is not issued to any other MN 41 so that the uniqueness in the subnet is maintained, and the nCoA is randomly issued by other MNs 41 through stateless address autoconfiguration. Even if are generated, it is guaranteed that their use is not allowed. It is desirable that these addresses be managed in association with a certain lifetime.
- FIG. 3 is a sequence chart showing an operation example when the MN performs a handover in the wireless communication system according to the present invention.
- each AR the information on which AR is the potential nAR is determined by the force collected after receiving the RtSolPr message, or the information accumulated and stored in the AR. Updated when there is (AR removal or addition).
- each AR acquires updated address information (nCoA) from ARs (potential nARs) existing in the geographical area, and replaces the address information stored in the table with the updated address information. Update with information.
- nCoA updated address information
- each AR stores, in a table in the address information storage means 51, address information (address information that can be used as nCoA) that can be used in each subnet of the AR present in a geographical periphery. It is possible to do.
- the adjacent subnet serving as the handover destination of the MN 41 also determines the identification information regarding the adjacent subnet such as a new connection point link layer address (New Attachment Point Link-Layer Address) included in the RtSolPr message. It is possible. Therefore, the pAR can determine the next handover destination of the MN41 based on the identification information on the adjacent subnet in the RtSolPr message, and select the nCoA required by the MN41.
- a new connection point link layer address New Attachment Point Link-Layer Address
- the first method is that the pAR immediately returns the FBack to the FBU without sending a HI message and waiting for a HAck message. That is, MN41
- a table address which is the address information storage means 51, is selected, and an address that can be used is selected, and the selected available address ( That is, FBack including nCoA) is returned.
- FBack including nCoA the selected available address
- the second method is that the pAR sends valid nCoA information to its MN 41 by means of a PrRt Adv message without waiting for an FBU message. That is, the pAR selects an address that can be used as the tape information which is the address information storage means 51 according to the RtSolPr message from the MN41, and immediately selects the usable address without waiting for the FBU message from the MN41. Send a PrRtAdv message containing the correct address (ie, nCoA). In this case, even if the connection between the MN and the pAR is lost before the FBU message is sent, the MN will continue its fast handover without having to encapsulate the FBU message in the FNA message. Can.
- the MN 41 can acquire valid nCoA information by using the PrRtAdv message transmitted from the pAR without transmitting the FBU message (or the FNA message). Note that even when the pAR provides valid nCoA information to the MN41 by using a message different from the PrRtAdv message, the MN41 can quickly obtain nCoA usable in the subnet after the handover.
- the HI message including the MN link layer address may be transmitted to the nAR.
- the nAR can recognize the MN and can issue an instruction to start the buffering.
- the MN 41 Valid nCoA information can be obtained before handover, and delay This results in smaller and less lost packets. Also, according to the second method described above, even when the FBU is not transmitted to the pAR due to disconnection or the like, the MN 41 can acquire valid nCoA information before the handover This results in a smaller delay and fewer lost packets.
- the present invention it is possible to reduce the time delay caused by message exchange and the like, to speed up the handover, and to reduce the delay to reduce the number of lost packets. It is also possible to reduce it.
- An access router device, a communication handover system using the same, and a communication handover method according to the present invention have a function of reducing a time delay caused by, for example, message exchange or the like to speed up handover, It is useful in technology fields such as high-speed wireless communication using handover technology in wireless communication systems using Mopile IPv6.
