Description
Technical field
The present invention relates to the communications field, relate in particular to mobile network's handoff technique.
Background technology
Mobile IP is the network layer solution that is moved by the support communication node that the Internet engineering duty group (The Internet Engineering TaskForce is called for short IETF) is formulated, and mobile IP has IPv4 and two kinds of versions of IPv6.Mobile IP adopts special routing mechanism by setting up map addresses, and the original IP of assurance individual node communicates to connect when internet roaming and is not interrupted, thereby realizes the state of " online all the time ".
Mobile IP is that mobile node has defined two kinds of IP addresses: home address (Home Address is called for short HoA) and Care-of Address (Care-of Address is called for short CoA).Wherein home address is used for this mobile node of only sign, is equivalent to the IP address of mobile node in the simple IP, and mobile node communicates by other nodes on home address and the Internet; Care-of Address is the temporary ip address that mobile node obtains at nonlocal access network, and mobile node is realized access and the data route of Internet by Care-of Address.Mobile IP is on home address and Care-of Address basis, introduce home agent (Home Agent, be called for short HA) this new mobile management entity, be responsible for safeguarding the mapping relations between home address and the Care-of Address, thereby guarantee mobile node IP communication continuity when field network is moved.
Mobile IP specific operation process is: mobile node to home agent registration binding home address and Care-of Address, is set up a route tunnel then between home agent and Care-of Address after field network obtains Care-of Address.Because mobile node with home address as its only sign, under default situations, the data message of Correspondent Node at first can normally be routed to the home network of mobile node, home agent by this mobile node is responsible for reception, home agent is routed to the Care-of Address of this mobile node to message by the tunnel according to the address mapping relation of setting up again, realizes that the message from the Correspondent Node to the mobile node receives.And for the communication of mobile node in the field network initiation, mobile node can directly send message with home address as source address at foreign link, such as MIPv4, perhaps message routing is acted on behalf of to the local with tunnel style, be transmitted to Correspondent Node by home agent again.Though the access address that mobile node is concrete, promptly Care-of Address is along with the mobile meeting of node changes, because the uniqueness of home address and the transfer of home agent, mobile node IP communication continuity is guaranteed.
Mobile network's (Network Mobility is called for short NEMO) as the extension of network of mobile IP v 6, has introduced this new network entity of mobile router MR, for all nodes in the network provide the mobility support, realizes that the transparent of whole network moves by MR.Support to compare for individual node provides to move with mobile IP protocol, NEMO supports for one or more subnet provides to move.
The existing protocol framework need carry out twice encapsulation to the related data message of the network node under the MR, and outermost layer is the CoA of MR and the tunnel between the HA, and the inside one deck is the HoA of MR and the tunnel between the HA.And the main improvement of another agreement is under the situation at CoA, and HA and MR only carry out the CoA of outermost MR and the tunnel encapsulation between the HA and do not carry out the HoA of the MR in it and the tunnel encapsulation of HA.
Fig. 1 is the quick switching flow figure of prior art prediction type MIPv4 node, Fig. 2 is the quick switching flow figure of prior art reaction equation MIPv4 node, as Fig. 1, shown in Figure 2, mobile node is when detecting new objective network, to former service couple in router (Previous Access Router, abbreviation PAR) sends quick bind request (Fast Bind Upgate, be called for short FBU) message, the new Care-of Address that has comprised this mobile node in this FBU message, the target information of access route, Foreign Agent (Foreign Agent, be called for short FA) and Care-of Address (abbreviation FA_CoA) pattern under home address or the information such as former Care-of Address under Co_located (self-configuring) the CoA pattern, former then service couple in router is set up new couple in router address and the home address under its FA_CoA pattern or the mapping relations of the former Care-of Address under the Co_located CoA pattern of this node, and former then service couple in router can begin data cached bag.
Implement in the process of the present invention the inventor, find that there is following defective at least in prior art: existing fast switch over method is designed primarily at portable terminal, switching for the mobile network, especially adopt the mobile network's of FA_CoA pattern quick switching, because switching to of mobile network is whole mobile, except needing one deck encapsulation with mobile network's one side, portable terminal one side also needs to add one deck encapsulation.

Embodiment
As shown in Figure 3, be embodiment of the invention mobile network's changing method embodiment one flow chart, concrete steps comprise:
The data message of the network entity of the buffer memory that step 110, the former service couple in router of reception send;
The mobile network's that the embodiment of the invention provides changing method sends to network entity by the data message that will send to the prefix information scope IP address that belongs to the network entity correspondence, thereby has realized the quick switching in the mobile network.The embodiment of the invention has effectively reduced in the process that the mobile network is switched fast, the overhead for data encapsulation between external agent and the network entity.
As shown in Figure 4, be embodiment of the invention mobile network's changing method embodiment two flow charts, present embodiment is that example is elaborated with a concrete prediction type NEMOv4 fast switching method in the mobile network, and concrete steps are:
Mobile network in the present embodiment is an example with the mobile network of the MIPv4 of employing FA-CoA pattern, network entity is with concrete mobile router (Mobile Router, be called for short MR) be example, then the mobile of the whole net of this mobile network is that unit carries out with the mobile router.
Particularly, the PAR information that obtains adjacent network according to the resource management or the communication between each router of network side.
After step 230, MR receive this objective network information, send FBU, carried mobile network's prefix information (Mobile network prefixes is called for short MNP) of MR correspondence among this FBU to PAR;
The Indication message of present embodiment can comprise switch indicating information or handoff request message etc.; Below be example with the switch indicating information.
In this step, NAR is according to whether comprising prefix information in the switch indicating information, or information such as the whole fast transferring indication of network, determine whether to carry out the whole switching fast of mobile network, if comprise relevant informations such as prefix information in the switch indicating information, whether then NAR judges according to the strategy or the out of Memory that are provided with in advance, support the whole of mobile network to switch fast.When if NAR does not support mobile network's quick switching, then the processing mode that moves according to main frame is handled or is refused and switches; If support, perhaps do not need acquiescence support through judging, then bind as step 250 pair prefix information.
The data structure of being bound by NAR can be as follows:
Binding?Table?of?MN{
the?link-layer?source?address?of?the?mobile?Router/Node
the?Home?Agent?address
the?Mobile?network?prefixes
the?new?care-of?address

}
As can be seen, except information such as the HA that carries MR, new CoA, NAR information, also carried pairing each MNP of MR, i.e. prefix information among the FBU; This prefix information can be illustrated as a field or other form, form that it is concrete and content can comprise a type, length, value (Type LengthValue, be called for short TLV) combination, comprise the combination in any such as information list, lifetime information separately, residue lifetime information separately, prefix length information and prefix quantity information of all relevant MNP.
NAR sets up the identification information of prefix information and MR such as the mapping between the link address, in fact exactly between the external agent of home agent and this MR, set up the tunnel, therefore the data message that will mail to the IP address that belongs to the network prefix information scope as NAR mails to network entity, the home address of mobile network's MR and the encapsulation between its home agent can be dispensed thus.
For the switching response message that the target couple in router sends, in general communication network, whether the target couple in router is agreed to switch, and mainly is the relative position according to terminal and mobile network, and the policy information of network.Terminal and mobile network's relative position as, terminal moves among this mobile network.The policy information of network comprises, the loading condition of network, too big as router load, or tactful load shedding etc., switch can also be according to the influence of user's CAMEL-Subscription-Information in agreement, whether to this target couple in router, allow this user to switch as the terminal transfer that whether allows this user, whether this user's handoff request is legal etc.Because present embodiment is under the network mobility pattern during in company with the terminal transfer of network bulk migration, owing to be the network bulk migration, so be that object is judged with this objective network.So at this moment, this prefix information is exactly this mobile network's of sign a information.Therefore just can determine whether move and how to move according to prefix information.After the target couple in router is received this prefix information or any message that comprises this prefix information, if this target couple in router can be discerned the parameter or the out of Memory of this prefix information, promptly this target couple in router has the ability to support overall network to switch fast, the target couple in router just can be according to prefix information so, or wait according to mobile network's user signing contract information local policy again and determine whether to allow its switching, and carry out safety check etc.Be with the different of prior art, prior art is judged according to IP address or Termination ID, present embodiment only judges according to prefix information, or according to prefix information and out of Memory, judges together such as the HA of MR, new CoA, target information of access route etc.
Whether support in the present embodiment that the whole information of switching fast of mobile network can be this network prefix itself, perhaps other is such as the sign of success or failure;
