Description
Technical field
The present invention relates to network communications technology field, particularly a kind of recognition methods of mobile router, system and device.
Background technology
Mobile IP (Internet Protocol, Internet Protocol) is the network layer solution that is moved by the support communication node that IETF (Internet Engineering TaskForce, internet engineering task group) formulates, and IPv4 and IPv6 version are arranged.Mobile IP adopts special routing mechanism by setting up map addresses, and assurance individual node its original IP in moving process communicates to connect and is not interrupted, and realizes always online.
NEMO (Mobile Network, with the network of whole network as a cell moving) as the mobile IP v 6 extension of network, introduced MR (Mobile Router, mobile router) this new network entity, purpose be by MR for all nodes in the network provide the mobility support, realize that the transparent of whole network moves.For providing to move, individual node supports that than mobile IP protocol NEMO supports for one or more subnets provide to move.MR on the basis of realizing the mobile IP v 6 all functions, also registers the prefix information MNP (Mobile NetworkPre-fix, mobile network's prefix) of its maintaining network as a special mobile node to home agent.After the home agent of MR received the network registry of MR, in the accessibility of local network operation mobile network prefix, being responsible for destination address was that the data message of MNP passes to MR in the tunnel encapsulation mode; On the other hand, MR passes to home agent with all messages of its network node in the tunnel encapsulation mode, normally is routed to each correspondent node through home agent
PMIPv6 (Proxy Mobile IPv6, proxy mobile IPv 6) also is a kind of expansion of mobile IP v 6, introduced MAG (Mobile Access Gateway, Mobile Access Gateway), LMA (Local MobileAnchor, local mobile anchor) two new network entities provide the mobility support by network side for the mobile node that does not possess the mobile management ability.When mobile node enters the PMIPv6 territory, network side is by announcing node subscription network prefix information to mobile node, " forgery " becomes the home network of mobile node, when mobile node moves in the PMIPv6 territory, when between different MAG, switching, network entity MAG replaces mobile node to carry out the registration binding of MIPv6 agreement regulation to LMA, LMA coordinates the processing of different MAG, to mobile node bulletin consolidated network prefix, cause mobile node " all the time " in consolidated network and do not need to carry out the mobile management operation.
NEMO has introduced the mobile router notion, because mobile router and traditional fixed router differ greatly, if use without distinction, may go wrong at following application scenarios:
(a) PMIPv6+NEMO scene, MR is as the serviced node in PMIPv6 territory;
(b) the nested scene of NEMO;
(c) NEMO optimizes scene;
(d) NEMO winding scene;
(e) NEMO router optimization scene;
(f) PMIPv6, NEMO is to the processing scene of MIPv6 node;
To above six kinds of problems that application scenarios may occur, specify as follows:
1, PMIPv6+NEMO scene, MR is as the serviced node in PMIPv6 territory
The hybrid network schematic diagram of PMIPv6 and NEMO as shown in Figure 1, the MAG among the PMIPv6 (MobileAccess Gateway, Mobile Access Gateway) is difficult to differentiate MR and MN (Mobile Node, mobile node), does not understand the MNP prefix.MR thinks that being in home network can not submit MNP information to yet when initial network entry, therefore cause the hybrid network of PMIPv6 and NEMO to be difficult to operate as normal.
2, the nested scene of NEMO
MR and FR (Fixed Router, fixed router) RA (Router Advertisement, advertising of route message) is as broad as long, and MN may select MR as default router in the level router process in the choice, the nested NEMO route that causes constituting is not optimized, as Fig. 2 and shown in Figure 3.MN receives the advertising of route RA message of mobile router MR and fixed router FR simultaneously.If select mobile router as default router, will inevitably be than selecting fixed router more routing cost and time delay to be arranged as default router.
3, NEMO optimizes scene
NEMO generally is not optimized route under nested scene, if be optimized, needs handling capacity to consult to determine concrete optimization pattern yet.Adopting which kind of mode that route is optimized is mobile router or fixed router must be distinguished the clear process that just can carry out.
4, NEMO winding scene
In the NEMO standard, not the router relation between each MR, but the relation of couple in router and serviced node, operation mobile IPv 6 protocol rather than Routing Protocol between the MR usually.Along with the nested appearance of NEMO, the situation of router winding may appear, as shown in Figure 4.Among Fig. 4, MR2 is default router with MR1, and MR3 is a default router with MR2, and MR1 is default router with MR3, thereby forms winding.When MR3 will send packet to the node on the internet, packet just can't be forwarded to NEMO in the circulation forwarding of winding the inside overseas.
5, NEMO router optimization scene
In the NEMO standard, there is the scene of two different mobile network MR communications, because the identity of MR has only home agent to discern at present, be difficult between the MR discern and limited the possibility of carrying out routing optimality between MR.At this moment, MR can't bind to opposite end MR, because must carry the H sign among the NEMO regulation BU (BindingUpdate, binding update messages).The routing optimality schematic diagram of NEMO as shown in Figure 5.
6, PMIPv6, NEMO is to the processing scene of MIPv6 node
Mobile IPv 6 node self can be realized mobile management, and PMIPv6, NEMO is the network management scheme at the design of node that does not possess mobile management, for mobile IPv 6 node, may not need PMIPv6 or NEMO service, perhaps PMIPv6 can take different tupes to dissimilar mobile nodes with NEMO.If can not distinguish node types, what may cause serving is mandatory, can not utilize resource fully.
Therefore, the shortcoming of prior art is: can not discern the identity of mobile router, if mobile router and fixed router are used without distinction, under above-mentioned 6 kinds of scenes, can not carry out normally or more optimization process.
Summary of the invention
The problem that the embodiment of the invention will solve provides a kind of recognition methods, system and device of mobile router, to realize the identity of identification mobile router, makes network function normally be reached more optimization process.

As shown in Figure 6, the flow chart for the recognition methods of embodiment of the invention mobile router specifically may further comprise the steps:
Step S601, the route messages that receiving device receiving end/sending end equipment sends, this route messages comprises.The NEMO ability information.Wherein, route messages comprises route request information and advertising of route message, and the NEMO ability information includes but not limited to the mobile router identification information.The embodiment of the invention has been revised the route request information (RS) in the Neighbor Discovery Protocol [RFC2461], by increasing the NEMO ability information, for example: the mobile router identification information, the node that expression sends this message is a mobile router, amended message is as shown in table 1.
Table 1
R flag bit in the table 1 is the mobile router identification information, and when this flag bit set, the sending ending equipment that expression sends this route request information is a mobile router; Otherwise, with this R mark position 0.Must ignore this flag bit for the receiving device of not supporting the scheme that the embodiment of the invention provides.Sending ending equipment adds the R flag bit in route request information, and this R flag bit is set, and the route request information that will carry this R flag bit then sends to receiving device.
Equally, the embodiment of the invention has been revised Neighbor Discovery Protocol [RFC2461] and has been defined and be moved IPv6[RFC3775] improved advertising of route message (RA), by increasing a NEMO ability information, for example: the mobile router identification information, the sending ending equipment that expression sends this advertising of route message is a mobile router, and [RFC3963] and the later relevant ability support of NEMO can be provided.Amended advertising of route message is as shown in table 2:
Table 2
R flag bit in the table 2 is the mobile router identification information, and when this flag bit set, the network equipment that expression sends this advertising of route message is a mobile router; Otherwise, with this R mark position 0.Must ignore this flag bit for the receiving device of not supporting the scheme that the embodiment of the invention provides.Sending ending equipment adds the R flag bit in advertising of route message, and this R flag bit is set, and the advertising of route message that will carry this R flag bit then sends to receiving device.
NEMO ability information in the embodiment of the invention is by DHCP (Dynamic Host ConfigureProtocol, the DHCP signaling) or AAA (Authentication AuthorizationAccounting, authentication, authorize, charge) message carry.In embodiments of the present invention, the sending ending equipment that sends route request information is the request access node, and the receiving device that receives route request information is a network equipment; The sending ending equipment that sends advertising of route message is a network equipment, and the receiving device that receives advertising of route message is an access node.Wherein, network equipment can be Mobile Access Gateway MAG, authentication and authorization charging server AAA Server etc.
Step S602, receiving device judge whether comprise the NEMO ability information in the route messages.After receiving this route messages, receiving device is at first followed the regulation of [RFC2461] the route request message is carried out legitimacy detection and follow-up processing, detects whether comprise the NEMO ability information in this route messages then.
Step S603, if comprise, then the sending ending equipment of receiving device identification transmission route messages has the NEMO ability.Be that example describes the sending ending equipment with NEMO ability with the mobile router in the embodiment of the invention, but the embodiment of the invention is not limited in this, the sending ending equipment of any NEMO of having ability all should fall into the protection range of the embodiment of the invention.If comprise the NEMO ability information in the route messages that receives, for example: the mobile router identification information, then the sending ending equipment of this route messages of receiving device identification transmission is a mobile router; If do not comprise the NEMO ability information, then the sending ending equipment of this route messages of receiving device identification transmission is not a mobile router, for example: may be mobile host or general stationary nodes.When the route messages that sends is route request information, the request access node that network equipment identification sends this route request information is a mobile router, after the request access node of this route request information of network equipment identification transmission was mobile router, this network equipment was acted on behalf of mobile management mode and/or routing optimization method for this mobile router provides; When the route messages that sends was advertising of route message, the network equipment that access node identification sends this advertising of route message was a mobile router.
The recognition methods of above-mentioned mobile router, in route messages, add and the NEMO ability information is set, thereby the receiving device that receives this route messages can being discerned send the sending ending equipment of this route messages is mobile router, thereby has remedied the defective that prior art can not be discerned the identity of mobile router.
As shown in Figure 7, be the operation chart of embodiment of the invention mobile router, specifically comprise following process:
701, send route request information:
For the mobile router of not supporting the embodiment of the invention, the regulation that should follow [RFC2461] sends route request information;
For the mobile router of supporting the embodiment of the invention, when the condition of the transmission route request information that satisfies [RFC2461] defined, mobile router must send route request information as shown in table 1; When network equipment identified the identity of mobile router by this route request information, this network equipment was acted on behalf of mobile management mode and/or routing optimization method for this mobile router provides.
702, send advertising of route message:
For the mobile router of not supporting the embodiment of the invention, the regulation that should follow [RFC2461] sends advertising of route message;
For the mobile router of supporting the embodiment of the invention, when the condition of the transmission advertising of route message that satisfies [RFC2461] defined, mobile router must send advertising of route message as shown in table 2;
703, receive route request information:
After receiving route request information, mobile router is at first followed the regulation of [RFC2461] the route request message is carried out legitimacy detection and follow-up processing;
Then, mobile router detects this mobile router identification information, for example: the R flag bit: if this R flag bit is set, the request access node that expression sends this route request information is a mobile router, can provide [RFC3963] and the later relevant ability support (such as the NEMO routing optimality) of NEMO if receive the mobile router of this route request information, then need to carry out the preparation that provides NEMO to be correlated with the ability support for the request access node; If be not set, then the node of this route request information of expression transmission is mobile host or general stationary nodes, and not needing provides NEMO relevant support for it.
704, receive advertising of route message:
After receiving route request information, mobile router is at first followed the regulation of [RFC2461] the route notice message is carried out legitimacy detection and relevant processing;
Then, mobile router detects this mobile router identification information, for example: the R flag bit: if this R flag bit is set, then the network equipment of this advertising of route message of expression transmission is a mobile router, the support that can provide [RFC3963] and later NEMO to be correlated with ability for the access node of being served; If this R flag bit is not set, then the network equipment of this advertising of route message of expression transmission is a fixed router, inserts the mobile router of this router and should carry out the preparation that becomes the root of NEMO mobile router.
As shown in Figure 8, operation chart for embodiment of the invention Mobile Access Gateway [ProxyMIPv6-02], Mobile Access Gateway MAG is the network entity of PMIPv6 defined [ProxyMIPv6-02], is equivalent to MIPv6[RFC3775] in AR (Access Router, couple in router).
After MAG receives route request information,
MAG at first follows the regulation of [RFC2461] the route request message is carried out legitimacy detection and follow-up processing;
Then, MAG checks the mobile router identification information in this route request information, for example: the R flag bit:
If the R flag bit is set, then expression request access node is a mobile router, so, when MAG represents this request access node when the home agent of this request access node sends agent binding message, just need in message, increase mobile network's prefix MNP option.Yet, if MAG can't increase the MNP option, such as not understanding the MAG of NEMO, MAG should refuse to provide PMIPv6 service to this node so;
Otherwise expression request access node is non-moving router, need not increase the MNP option in agent binding message.
In the embodiment of the invention, the operation of mobile host is also revised, at MIPv6[RFC3775] in, binding life cycle of local registration is the longest to be 420 seconds.For the mobile host that inserts under mobile router, if in the long time, mobile host keeps static relatively with respect to mobile router, for example: mobile router on the aircraft and passenger's portable terminal.So, 420 seconds the longest binding will make mobile host initiate the local registration too much life cycle.Equally also there is similar problem in the opposite end registration of portable terminal.So the embodiment of the invention is revised the operation of mobile host:
After receiving advertising of route message, mobile host
At first follow the regulation of [RFC2461] the route notice message is carried out legitimacy detection and follow-up processing;
Check the mobile router identification information in this advertising of route message then, for example: the R flag bit:
If this R flag bit is set, what identification sent this advertising of route message so is mobile router, and mobile host can be selected be made as bigger value the life cycle of local registration and opposite end registration, reduces times of registration;
If the R flag bit is not set, what identification sent this advertising of route message so is general fixed router, and then mobile host is about the regulation of selecting follow [RFC3775] life cycle of local registration and opposite end registration.
The above-mentioned a kind of mode that just route announcement RA message is provided with can also be carried out following setting to RA message, makes this RA message: have the R flag bit, clear and definite Router identity; Have Router grade option, be convenient to the MR of subordinate and select acquiescence Router, avoid nested; Have Root MR CoA option, be convenient to MR and in BU message, point out HA to carry out nested optimization; Have the N flag bit, show the protocol definition of supporting NEMO RFC3963, corresponding ability support is provided.
Equally also can carry out following setting, make this RS message: have R sign position, show that this is a mobile router of supporting RFC3963 or NEMO related protocol route request RS message; Have N sign position, show that mobile router/portable terminal requirement network equipment provides RFC3963 promptly relevant NEMO agreement support.
Above-mentionedly can be used in combination, even it comprises N/R sign position simultaneously being provided with of RA message, RS message.More than just add several preferably modes of sign position in RA message, RS message, any RA message, RS message are made amendment makes its mode that can identify the mobile router identity all should fall into the protection range of the embodiment of the invention.
