Embodiment
In order to realize when switching between mobile node generation heterogeneous network, quicken the handoff procedure of mobile node by pre-authentication, first embodiment provided by the invention is the method for switching between a kind of heterogeneous wireless network, mobile node is prepared to switch between heterogeneous wireless network, move out wireless local area network AP institute coverage as a MN (Mobile Node mobile node), the base station overlay area that enters wireless wide area network is prepared to switch, and this method flow comprises as shown in Figure 1:
Step 101: service network (as WLAN (wireless local area network)) network side entity (as AP) issues the pre-authentication information of supporting about objective network (as wireless wide area network) ability to MN.
The pre-authentication information that step 102:MN issues according to network side entity is determined the pre-authentication information with its coupling, initiates the pre-authentication of objective network.
Step 103: after pre-authentication passed through, MN switched between heterogeneous network.
According to above-mentioned steps as seen, before switching between the heterogeneous wireless network, MN has obtained the pre-authentication information of supporting about the objective network ability, and has carried out pre-authentication, has quickened the handoff procedure of mobile node at heterogeneous network just because of MN.
Wherein pre-authentication information is: need negotiation parameter and ability information collection in advance in the pre-switch process.The pre-authentication information about objective network that the network side entity of service network issues to MN can be following any one or combination:
The access style of objective network: as Wifi, Wimax, 3GPP, 3GPP2 etc.;
The access authentication mode of objective network: as EAP, X.509 etc.;
The key schedule that objective network needs: as MD5, SHA etc.;
Whether objective network supports pre-authentication: be not or not.
Concrete issue can be by router advertisement message, dhcp message, PPP message, EAP message, media-independent message or special-purpose pre-authentication signaling wait and realize.
Second embodiment provided by the invention is the method for switching between a kind of heterogeneous wireless network, and when MN prepares to switch between heterogeneous wireless network, method flow comprises as shown in Figure 2:
Step 201: the network side entity of service network receives the pre-authentication information that MN reports the objective network of this MN ability support.
Step 202: the network side entity of service network is selected the pre-authentication information of objective network ability support according to the pre-authentication information of the objective network that MN reports, and only the pre-authentication Information Selection of the objective network of this MN ability support is come out, and sends to MN.Perhaps network side entity only sends a confirmation to MN, the pre-authentication information of the objective network of giving MN that the network side entity of expression service network issues in advance, and the pre-authentication information of the objective network that reports with MN is identical.
Step 203:MN is according to pre-authentication information or confirmation that network side entity issues, just obtained the pre-authentication information with its coupling, initiates the pre-authentication of objective network.
Step 204: after pre-authentication passed through, MN switched between heterogeneous network.
Because MN at first initiatively reports the pre-authentication information of the objective network of its ability support, the network side entity of service network can be selected according to the information that mobile node initiatively reports like this, only selection is issued MN with the pre-authentication information of the objective network of this MN coupling, adopt this method, MN can defaultly judge, the pre-authentication information that network side entity issues is exactly the pre-authentication information with its coupling.Network side entity will all not be handed down to MN with MN coupling and unmatched information like this, allows MN select to confirm.
MN reports the pre-authentication information of the objective network of its ability support to comprise in the step 201: whether support any one or combination of pre-authentication and relevant authentication priority as access style, the access authentication mode of objective network, the key schedule of objective network needs, the objective network of objective network, as: MN reports its supported information to have: the access style of objective network: Wimax, 3GPP; The access authentication mode of objective network: EAP; The key schedule that objective network needs: MD5; Whether objective network supports pre-authentication: be.
In step 202, the network side entity of service network from the pre-authentication information of objective network as " access style of objective network: Wifi, Wimax, 3GPP, 3GPP2; The access authentication mode of objective network: EAP, X.509; The key schedule that objective network needs: MD5, SHA; Whether objective network supports pre-authentication: be not or not " in select the information that the supported pre-authentication information of selecting to report with MN is complementary: " access style of objective network: Wimax, 3GPP; The access authentication mode of objective network: EAP; The key schedule that objective network needs: MD5; Whether objective network supports pre-authentication: be "; and by the message of router advertisement message, DHCP (Dynamic host configuration protocol DHCP) message, PPP (Point to point Protocol point-to-point protocol) message, EAP (ExtensibleAuthentication Protocol can expand authentication protocol) message, media-independent or special-purpose pre-authentication signaling etc. with above-mentioned information promptly: " access style of objective network: Wimax, 3GPP; The access authentication mode of objective network: EAP; The key schedule that objective network needs: MD5; Whether objective network supports pre-authentication: be " send to MN.Wherein the message of media-independent includes but not limited to: the network inquiry message of obtaining network information message or media-independent of media-independent.
In the above example, to report the pre-authentication information of the objective network of its ability support can also be following any one or combination to MN:
The access style of objective network: as Wifi, Wimax, 3GPP, 3GPP2 etc.;
The access authentication mode of objective network: as EAP, X.509 etc.;
The key schedule that objective network needs: as MD5, SHA etc.;
Whether objective network supports pre-authentication: be not or not.
Report the pre-authentication information of the objective network of its ability support only need comprise as MN: " access style of objective network is Wimax and supports pre-authentication; and the key schedule that the access authentication mode of objective network and objective network need can be determined according to predetermined policy is default according to the access style of objective network.Implementation concrete in the different application may be different, repeat no more herein.
In the step 204, when MN switches, can adopt the handoff procedure of prediction type between heterogeneous network, perhaps the handoff procedure of reaction equation.
According to 2 top embodiment as can be seen, it no matter is the network side entity of the service network among the embodiment 1 issues technical scheme from the pre-authentication information of supporting about the objective network ability to MN, still the MN among the embodiment 2 reports the technical scheme of pre-authentication information, it all is a kind of specific implementation method of mobile node required pre-authentication information when determining pre-authentication, after this mobile node is determined pre-authentication information according to the method among embodiment 1 or the embodiment 2, perhaps MN can also be by carrying out after information interaction determines pre-authentication information with core-network entities, just can initiate the pre-authentication of objective network, after pre-authentication passed through, mobile node just can switch between heterogeneous network fast.
When MN works in heterogeneous network, move frequent, can switch between the heterogeneous networks through being everlasting, when MN switches between heterogeneous network, by context transfer mechanism, the network side entity of service network transmits the pre-authentication information that the mobile node ability is supported to target network entity, and target network entity goes out the pre-authentication information of mating with MN according to the pre-authentication Information Selection of MN ability support, and announces its selected pre-authentication information to MN.Concrete pass through mechanism comprises that switchable resource inquiry request message, the switching indication by media-independent realizes transmitting or transmit by machine-processed realization of other context transfer.Can realize also that by this method MN obtains the pre-authentication information of the objective network of its coupling.In target network entity when MN announces its selected pre-authentication information, can transmit by the network side entity of service network, the network side entity of service network was just transmitted this pre-authentication information and was not done other processing this moment, promptly by first advertisement service network of network side entity, announce the selected pre-authentication information of target network entity by the network side entity of service network to MN then in service network, perhaps target network entity is directly announced its selected pre-authentication information to MN.
Also may get along well service network or objective network of MN carries out the mutual of pre-authentication validation of information, but the pre-authentication information of directly supporting with the MN self-ability required pre-authentication information during as pre-authentication, and then the pre-authentication of initiation objective network, so just might exist, the incompatible situation of pre-authentication information that pre-authentication information that the mobile node ability is supported and objective network ability are supported, as: the MN self-ability supports that the access authentication mode of objective network is EAP, and the access authentication mode that the objective network ability is supported is for X.509, in this case, target network entity can send one to mobile node and be used to represent the incompatible information of pre-authentication information each other, MN know its can't realize and this objective network between pre-authentication, MN can initiate pre-authentication to new objective network.
Certainly, if MN carries out the mutual of pre-authentication validation of information according to mentioning method or additive method and service network or objective network in the previous embodiment, also may take place and the incompatible situation of objective network pre-authentication information, in this case, target network entity can send one to mobile node and be used to represent the incompatible information of pre-authentication information each other, this moment MN also know its can't realize and this objective network between pre-authentication, and can initiate pre-authentication to new objective network.
Quick MIP handoff procedure below in conjunction with the quick pre-authentication of support of IEEE802.21 is described further.The MIP handoff procedure comprises two kinds of prediction type and reaction equations fast.But, no matter adopt which kind of mode and IEEE802.21 in conjunction with the time, after pre-authentication process should being finished earlier, if follow-up MIP fast handover procedures is implemented in success again.Be that example illustrates this process with the quick MIP handoff procedure of prediction type below.
The 3rd embodiment provided by the invention is the method for switching between a kind of heterogeneous wireless network, and method flow comprises as shown in Figure 3:
Step 301:MN is (as the Mobile Node among Fig. 3, MIHF wherein is the functional module of this Mobile Node) get access to the information of neighbor networks (comprising the target network entity that preamble is described) on every side from information server (as the MIIS Server among Fig. 3) as the Candidate Network1 among Fig. 3.The message that adopts this moment be exactly media-independent obtain network information message.
Step 302:MN is initiated to the resource query request that candidate network (Candidate Network1) is the target network entity of correspondence in the preamble, with the resource availability of query candidate network.The message that adopt this moment is exactly the network inquiry message of media-independent.
The route finding process of step 303:MN and service network (as the Servering Network among Fig. 3).Can send route active request signaling to service network by mobile node alternatively, act on behalf of advertising of route message to MN (this step can carry out simultaneously with the resource availability inquiry) to require service network to send out.
MN and network side entity all have information interaction to carry out in step 301, step 302 or step 303.With these information is carrier, and can realize that on the basis of these information interactions in the foregoing description 1 step 101 is finished: the network side entity of service network issues pre-authentication information to MN.What perhaps step 201 and step 202 were finished among the embodiment 2: MN reports and pre-authentication information, and network side entity is selected according to the pre-authentication information that MN reports, only the pre-authentication Information Selection of the objective network of this MN ability support is come out, and send to MN.Top example is a kind of preferred scheme, this programme is not limited to certain concrete signaling, the signaling that any network side entity that can carry service network in the step 101 issues to MN about the pre-authentication information of objective network, all can realize support to this programme, those skilled in the art pass through foregoing description, just can be in specific implementation process revise concrete signaling, or the pre-authentication signaling of self-defined new special use realizes the support to this programme according to applied environment.For step 201 and step 202 the pre-authentication information that will determine alternately be not limited to concrete signaling equally, repeat no more herein.
Step 304: the selected objective network that switches of mobile node.
Following step 305, step 306, step 307 step do not require and must carry out in proper order, but consider to have advised carrying out step 306, step 307 again after the step 305 from the purpose angle of network security and pre-authentication.
Step 305: mobile node carries out the configuration of NCoA.
Step 306: the pre-authentication information of the relevant objective network that obtains from network side according to aforementioned process MN or MN by with the mutual pre-authentication information of determining of network side, MN and objective network carry out pre-authentication process.Concrete pre-authentication process is transparent to bottom.The signaling of IEEE802.21 provides carrying that the upper strata is authenticated signaling and encapsulates, and informs that by sign service network passes to objective network and carries out pre-authentication, and authentication result is returned to MN.We are that example describes with the required verification process of Wimax mobile node networking for concrete process.
Define new message MIH_MN_HO_Pre-auth.Transfer.Objective network information judgement by wherein indication is the present networks processing or continues to be given to objective network.The concrete signaling of EAP can adopt existing standard signaling, and as shown in Figure 4, the concrete signaling procedure of EAP is omitted.Here only illustrate the initial of its process.Its cardinal principle is for to be encapsulated in the EAP signaling among the MIH_MN_HO_Pre-auth.Transfer.And and then finish pre-authentication process.When objective network judges that according to indication information thereby belonging to this network processes carries out with the decapsulation of EAP signaling and with AAA alternately.Until end.Produce the required key of both sides then.And then carry out the follow-up network process of going into.By whether successful judgement can know whether this mobile node is allowed to the target approach network, thereby can in time select suitable networks to insert.
This process can be carried out after having determined objective network, also can think that all candidate network all initiate this process before the objective network in decision.Scene decision is looked concrete in concrete selection.
The concrete signaling format of MIH_MN_HO_Pre-auth.Transfer message can for:
MIH_MN_HO_Pre-auth.Transfer(
SourceIdentifier，
DestinationIdentifier，
PreAuthenticationContainer
)
The wherein description such as the table 1 of parameter:

| SourceIdentifier | The MIHF identifier | The sign of the MIHF functional entity unit of message originator is used to identify the initiator of this message |
| DestinationIdentifier， | The MIHF identifier | The sign of far-end MIHF functional entity unit is used to identify the destination of this message |
| PreAuthenticationContainer | TBD | Message container is used for the relevant pre-authentication message of packaged media |
Table 1
After pre-authentication passes through, realize that by subsequent step MN switches between heterogeneous network.
Step 307:MN sends out handoff request to service network, carries the information of the pre-authentication information resources of wanting the reserved target network in the message.Service network is transmitted to objective network with this information, request target network reservation resource, and do the relevant preparation of switching.The objective network reserved resource and be ready to complete after, service network is sent out switching response message to MN, indication MN is established to layer 2 the connection of objective network.
Step 308:MN initiates fast moving IP binding procedure, sets up data channel between service network and objective network.Service network carries out quick binding acknowledgement, and data cached bag is transmitted to objective network.
The layer 2 that step 309:MN is established to objective network connects.
Step 310: layer 2 connects to set up finishes link activation.
The IP that step 311:MN returns to objective network connects.
Step 312:MN request target network issues cached data packet, and objective network will shift the packet of coming from service network and be handed down to MN.
Step 313:MN carries out registration/Binding Update of MIP.
Step 314: switch and finish, objective network notification service network sweep resource, objective network becomes the current service network of MN.
Above step 307 is a kind of preferred version that MN switches between heterogeneous network to step 314, and in order to realize switching between the heterogeneous network, the handover scheme under the different mechanisms may be different, repeats no more herein.
