The method comprises: (1), when renumbering of a home network prefix (HNP) of a mobile node (MN) occurs, a local mobility anchor (LMA) distributes a new HNP to the MN; (2), the LMA sends an update notification (UPN) message to an MAG, wherein the UPN message includes an HNP option and an MN identifier option; (3), the MAG determines that the LMA configures the new HNP to the MN according to the received UPN, the MAG constructs a router advertisement (RA) based on the UPN and sends the RA to the MN; (4), the MAG sends the UPA message to the LMA to notify updating completion of the prefix information; and (5), after the MN determines the HNP changing based on the received RA, a new HNP configuration communication address is employed. Therefore, the HNP updating time delay can be reduced effectively.
Description
Technical field
The present invention relates to a kind of method that in proxy mobile IPv 6, network prefix actively reconfigures, belong to networking technology area.
Background technology
In recent years, radio network technique and developing rapidly of application service have started the mobile computing epoch.But in conventional mobile communications net, mobile management is carried out at link layer.Along with to IP-based packet switching network transition, link layer mobility can not solve different IP subnet and switch the problem brought.Then IETF has started research and the standardization effort of network layer mobility agreement.Initially, the network layer mobility agreement that IETF proposes is all based on client, such as mobile IP v 6 (MobileIPv6, MIPv6) and Extended Protocol thereof.But mobility management protocol based on terminal exists some drawbacks, take Radio Resource etc. if desired for updating the software of existing terminal, increase terminal complexity and electric quantity consumption, a large amount of mobility signaling.Considering based on these factors, IETF has set up NetLMM working group, proposes network mobility management protocol demand.After long-term discussion, formally issue proxy mobile IPv 6 (ProxyMobileIPv6, PMIPv6) standard.Network mobility management protocol need not terminal and participates in mobility management process, and all of mobility signaling is all completed by network, which solves the functional requirement problem to terminal and the problem of waste of radio resources.
PMIPv6 is to introduce local mobile anchor (LocalMobilityAnchor, LMA) and two new functional entitys of Mobile Access Gateway (MobilityAccessGateway, MAG) on the basis of MIPv6.LMA supports the function of HA in MIPv6, and is extended its banding cache.In addition, LMA is that each MN distributes a unique prefix (HomeNetworkPrefix, HNP), for mobile node (MobileNode, MN) occur to keep constant during location change, affected so that its upper layer application is not switched by node.But if owing to the HNP that following three kinds of reasons cause MN distribution occurs network to renumber, the network operating feature of the most current PMIPv6 cannot be actively discovered this change thus distribute new HNP for MN timely.
1) PMIPv6 service provider obtains HNP set from upstream ISP distribution, if it occur that the change of ISP, then needs to update its HNP set；
2) in multiple LMA may co-exist in the network of same PMIPv6 service provider, if mobile node has substituted LMA but transfer is not the HNP of its distribution, then need new LMA to redistribute HNP；
3) due to the change of the network architecture, it is likely to result in the change of prefix information.
In mipv 6, mobile management is controlled by MN oneself, when home network generation network prefix renumbers, by mobile prefix, home agent can find that (mobileprefixdiscovery) mechanism upgrades in time to MN, so that the home address that its configuration is new.In PMIPv6 basic agreement, although contemplate the probability that HNP renumbers, but the solution (seeing RFC5213, Section6.12) that specification is relevant the most in the standard.
Summary of the invention
It is an object of the invention to provide a kind of method that in proxy mobile IPv 6, network prefix actively reconfigures.The present invention, on the basis of PMIPv6 basic agreement, proposes a kind of extension mechanism based on RFC7077, supports that LMA is to the MAG mobile session parameter of actively revision.The present invention, based on RFC7077, supports the active arrangement in the case of in PMIPv6 renumbering network prefix, and main innovation point content is as follows:
(1) when the generation change of network prefix HNP, LMA actively transmission renewal notice (UpdateNotification, UPN) message, to MAG, carries out the initialization that HNP reconfigures；In PMIPv6 agreement, HNP, as main MN configuration information, is its distribution by LMA, so HNP occurs change to be to be triggered by LMA.
(2) after MAG receives this UPN message, by router advertisement (RouterAdvertisement, RA) notice two prefixes to MN, wherein vital values corresponding for old prefix HNP is set to 0, the corresponding vital values of new prefix HNP is set to the value more than 0；Or notice new home address (HomeAddress, HoA) by DHCP (DynamicHostConfigurationProtocol, DHCP) message to MN；
(3), after MN receives this router advertisement, delete old HNP immediately, and use new HNP effectively location.
The technical scheme is that
1. the method that in proxy mobile IPv 6, network prefix actively reconfigures, the steps include:
1) when network prefix HNP of mobile node MN renumbers, local mobile anchor LMA is that this MN distributes a new HNP；
2) this LMA sends to Mobile Access Gateway MAG and updates notice message UPN, wherein comprises HNP option and MN identification options；Wherein, HNP option carries new HNP information, and MN identification options carries the identification information that MN is corresponding；
3) this MAG according to this UPN received determine LMA be this MN be configured with new HNP time, this MAG according to this UPN structure router advertisement message RA be sent to this MN；
4) this MAG sends to update and confirms that message UPA message completes to this LMA, the renewal of advertised prefix information；
5), after this MN determines HNP change according to router advertisement message RA received, new HNP is used to configure mailing address.
Further, described router advertisement message RA is carried two prefix information option；Wherein, comprising former HNP in first prefix information option, its available lifetime is set to 0, comprises new HNP in second prefix information option, and corresponding time parameter is more than 0.
Further, when mobile node MN receives this RA, former HNP will be abrogated and enable new HNP.
Further, when network prefix HNP of mobile node MN renumbers, LMA will retain the former HNP of this MN and is set to transitory state；During transitory state, LMA will no longer outwards issue the routing update message about former HNP, and LMA only receives and transmit the packet that descending destination is former HNP.
Further, described step 4) in, after LMA receives UPA message, with the former HNP of this MN replacing with this new HNP, acquiescence abandons any packet about this former HNP.
A kind of method that in proxy mobile IPv 6, network prefix actively reconfigures, wherein, proxy mobile IPv 6 network uses DHCP to be that this MN configures HNP, the steps include:
1) when network prefix HNP of mobile node MN renumbers, local mobile anchor LMA is that this MN distributes a new HNP；
2) this LMA sends to Mobile Access Gateway MAG and updates notice message UPN, wherein comprises HNP option and MN identification options: HNP option carries new HNP information；MN identification options carries the identification information that MN is corresponding；And this new HNP is sent to Dynamic Host Configuration Protocol server by this LMA；
3) MAG receiving UPN will ask the new HoA of this MN to this Dynamic Host Configuration Protocol server, then notices the dhcp message comprising this new HoA to this MN；
4) this MAG according to this UPN received determine LMA be this MN be configured with new HNP time, this MAG according to this UPN structure router advertisement message RA be sent to this MN；
5) MAG sends to update and confirms that message UPA completes to this LMA, the renewal of advertised prefix information；

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is explained in further detail.
The operating process of the present invention is as shown in Figure 1.
1, assuming that MN uses the address of current HNP configuration to be MN-HoA1, the address using new HNP to configure is MN-HoA2, and basic operation flow process is:
1) when the HNP of MN renumbers, LMA is the HNP that this MN distribution is new；
2) LMA sends UPN message to MAG, wherein comprises HNP option and MN identification options: HNP option carries new HNP information；MN identification options carries the identification information that MN is corresponding；Additionally, notice reason (NotificationReason) flag bit in UPN message is set to session parameter updates respective value 2 by LMA, it is used for representing the renewal (UPDATE-SESSION-PARAMETERS) that this is session parameter；
3), after MAG receives this UPN, find that LMA is that this MN assigns new HNP, thus recognize that the old HNP of MN is the most invalid；
4) MAG sends router advertisement message according to the new HNP carried in UPN, wherein the vital values of old HNP is set to 0, and the vital values of new HNP is set to the value more than 0；If PMIPv6 network uses DHCP to be that this MN configures HNP, new HNP is updated dhcp server functionality module by LMA, the MAG receiving UPN will ask the new HoA of MN further to dhcp server functionality module, and then actively send dhcp message to MN, notices new HoA；
5) additionally, MAG sends to update confirms that message (UpdateAcknowledgement, UPA) message completes to LMA, the renewal of advertised prefix information, such that it is able to make LMA receive and forward the packet being sent to new HNP；
6) MN receiving router advertisement or dhcp message recognizes that HNP changes, thus deletes the existing address on interface, and uses new HNP to configure effective mailing address.
2 session managements
Because the change of HNP would potentially result in inefficacy or the data-bag lost of the existing session of MN, to this end, this patent two kinds of session management patterns of proposition:
1) soft mode formula
In such a mode, LMA will temporarily retain the old HNP of MN, and be set to transitory state (as based on RFC6058).But the route caused in order to avoid the different LMA of same HNP ownership is chaotic, LMA will no longer outwards issue the routing update message about old HNP, and LMA only accepts and transmits the packet that descending destination is old HNP.
2) die formula
After LMA receives UPA message, replacing old HNP immediately is new HNP.Acquiescence abandons any packet about old HNP.
3 extension of message
In order to notice new HNP to mobile node in time and make waste and old HHP, MAG needs to use RA message or dhcp message, is introduced the HNP update mechanism under two kinds of scenes below:
1) based on RA
When MAG uses RA information updating HNP, need to carry two prefix information option (PrefixInformationoption), in first prefix information option, comprise old HNP, but the available lifetime of correspondence (ValidLifetime and PreferredLifetime) is both needed to be arranged to 0.Comprising new HNP in second prefix information option, corresponding time parameter all should be greater than 0.When mobile node receives such RA, it will actively abrogate old HNP and enable new HNP.
2) based on DHCP
When the HoA configuration that PMIPv6 uses DHCP to move node, it is necessary to configure a HoA belonging to new HNP for mobile node.When MAG receives UPN message, the HoA that please will look for novelty to corresponding Dynamic Host Configuration Protocol server, newly configured HoA will be actively sent to mobile node according to DHCP protocol by MAG subsequently.When mobile node receives such new HoA, it will actively abrogate old HoA and enable new HoA.
3) UPN message
In LMA is sent to the UPN message of MAG, notices reason and be arranged to 2 (UPDATE-SESSION-PARAMETERS), represent that this is the renewal to session parameter.Additionally, in UPN message, it is necessary to carry the mark that HNP option is corresponding to carry new HNP with MN respectively with MN identification options.
