Description

The method of one kind of multiple access way access networks, access device and authenticating device
Technical field
The present invention relates to communication technical field, method, access device and the authenticating device of one kind of multiple access way access networks that relate in particular to.
Background technology
The widely used transmission control protocol in existing internet/internet interconnection protocol (TransmissionControl Protocol/Internet Protocol; TCP/IP) in; The IP address has dual-use function; That is: both as the station location marker of communication terminal host network interface in network topology of network layer, again as the identify label of transport layer host network interface.Do not consider the situation that main frame moves at the beginning of the TCP/IP design.But when main frame moved more and more generally, the semanteme overload defective of IP address was obvious day by day.When the IP address of main frame changed, not only route will change, and the identify label of communication terminal main frame also changes, thereby can cause routing overhead more and more heavier, and the variation of host identification can cause using and the interruption that is connected.The purpose that identify label separates with station location marker be for the semanteme overload that solves IP address among the TCP/IP and routing overhead serious; And problem such as fail safe; Thereby the dual-use function of IP address is separated, realize the support that the problems such as exchanging visit between the heterogeneous networks zone in routing overhead and the Next Generation Internet are dynamically heavily distributed, alleviated in mobility, many locals property, IP address.
For addressing the above problem; The network architecture that multiple identify label separates with station location marker has been proposed at present; Comprise that (Host Identity Protocol HIP), location identity separated protocol (LISP), all belongs to identify label and locator separation network to host identity protocol.
(application number is the one Chinese patent application of CN200910174826.9 for identify label shown in Figure 1 and locator separation network framework; The applying date is on October 17th, 2009); For describing conveniently, hereinafter abbreviates this User Identity and locator separation network as SILSN (Subscriber Identifier & LocatorSeparation Network); SILSN comprise access server (Access Service Node, ASN), subscriber equipment (User Equipment, UE) with identify label and location registers register (Identification& Locater Register, ILR) etc.Wherein ASN is used for inserting subscriber equipment, is responsible for realizing the access of subscriber equipment, and bears functions such as charging and switching, and ILR bears user's Location Registration and identity recognition function.Wherein, ASN is a logic entity; Can be service universal packet wireless business be engaged in (GeneralPacket Radio Service) support node (Serving GPRS Support Node, SGSN), Gateway GPRS Support Node (Gateway GPRS Support Node, GGSN), group data service node (Packet Data Serving Node; PDSN) and BAS Broadband Access Server (Broadband RemoteAccess Server BRAS) waits equipment.Above-mentioned ILR can be key management system (Key Management System in concrete application scenarios; KMS), attaching position register (Home LocationRegister; HLR), home subscriber server (Home Subscriber Server; HSS), mandate/authentication/accounting server (Authorization, Authentication, Accounting, AAA) and other bear the entity of end-to-end key management and negotiation functionality.
In SILSN; The user is to insert identifier (Access Identification; AID) sign (identity that is used for identifying user); (each user and ASN have oneself independently AID or RID to ASN for Route Identification, RID) sign (position that is used for the identifying user place) with Route Distinguisher.When a user (like the UE1) access network among the SILSN, register its position (which ASN promptly registers this UE1 is positioned under) through ASN to ILR earlier.ILR sets up user's AID and the corresponding relation of the RID of the ASN that is inserted after the UE1 registration.If UE1 needs and the UE2 communication afterwards, after UE1 sent data message, by the position of ASN1 to ILR inquiry UE2, promptly which ASN UE2 was positioned under, and UE2 is positioned under the ASN9 among Fig. 1.ASN1 sends to corresponding ASN9 with data message then, and the data message after ASN9 will handle again sends to UE2.
Above-mentioned network has well been realized user's identify label and separating of station location marker, when subscriber equipment moves and roams, does not need to change identify label again, has guaranteed the continuity of business in the moving process.Route autgmentability and fail safe also significantly improve.

In existing SILSN: SILSN does not design to plurality of access modes.Therefore; When subscriber equipment adopts the plurality of access modes access network; Just can only all distribute a different AID, be equivalent to same subscriber equipment and used different access identifiers to insert, run counter to the user's request that inserts the identifier uniqueness for every kind of access way of each subscriber equipment.
Simultaneously; Same subscriber equipment has different identify labels; Can't merge the maximum bandwidth of using plurality of access modes when making subscriber equipment be linked in the network, can not when an access link interrupts, seamlessly switch to the link that another one inserts through plurality of access modes.In addition, be the behavior of a subscriber equipment originally, but show as a plurality of access identifiers, be unfavorable for that state security department monitors the user and trace to the source, influenced the fail safe of network.
And also there is same problem in the network architecture that other identify labels separate with station location marker.

Embodiment
In identify label and network that station location marker separates, each user has two identifiers, that is: AID and RID, the identity of AID representative of consumer wherein, the position of RID representative of consumer.When the user adopted the plurality of access modes access network, in order to keep the uniqueness of user identity AID, AID must remain unchanged, and so just has only by RID and has distinguished each access way of user.
The invention provides the method for a kind of user through the plurality of access modes access network; Be applied to the network that identify label separates with station location marker; This method comprises: the user terminal that has same user's identify label adopts the plurality of access modes access network through the one or more access nodes with diverse location sign; Wherein, said access way is corresponding one by one with said station location marker, and said plurality of access modes is corresponding to said user's same identify label.
Wherein, access node has one or more station location markers;
When user terminal adopted the plurality of access modes access network through an access node with diverse location sign, said access node had a plurality of station location markers, every kind of corresponding station location marker of access way;
When user terminal adopted the plurality of access modes access network through a plurality of access nodes with diverse location sign, each access node had a station location marker, the station location marker of every kind of corresponding access node of access way; Perhaps
When user terminal adopted the plurality of access modes access network through a plurality of access nodes with diverse location sign, access node had one or more station location markers, every kind of corresponding station location marker of access way.
Access way among the present invention comprises: wireless lan (wlan), GPRS (GPRS), WCDMA (WCDMA), TD SDMA (TimeDivision-Synchronous Code Division Multiple Access; TD-SCDMA), (the Point-to-Point Protocol over Ethernet of the point-to-point protocol on the Ethernet; PPPoE);, micro-wave access global inter communication (Worldwide Interoperability for Microwave Access, WiMAX), in the Long Term Evolution (LTE), CDMA2000 access way one or more.
Hereinafter will combine accompanying drawing that embodiments of the invention are elaborated.Need to prove that under the situation of not conflicting, embodiment among the application and the characteristic among the embodiment be combination in any each other.In the embodiments of the invention, be that example describes with SILSN, but the present invention is not limited to this, can be applied to the network that other identify labels separate with station location marker equally.
For distinguishing same user's plurality of access modes; When same user adopts the plurality of access modes access network among the SILSN; Can use single AID to identify (promptly identifying unique AID of this user identity), but support the access server of different access waies to have different RID as inserting.Be that different access waies must be registered under different ASN, perhaps, different access waies is through having the same ASN registration of different RID.More precisely, be exactly same user when adopting different access waies to insert, the ASN that is inserted must possess different RID, access way is corresponding one by one with RID.
For guaranteeing that the user can adopt different access waies normally to insert; In a kind of technical scheme provided by the invention; Different access waies can only insert different access servers, more strictly speaking, is that plurality of access modes can not insert the access server with same RID address.As shown in Figure 2; Adopt WLAN when the user passes through UE1, (Code Division Multiple Access is during CDMA) with three kinds of access way access networks of WCDMA for code division multiple access; Three kinds of access waies have inserted ASN1, ASN2 and ASN3 respectively, thereby realize through the plurality of access modes access network.
In another kind of technical scheme, in actual deployment, the user passes through subscriber equipment when inserting somewhere operator; Certain ASN of this operator can support to adopt simultaneously plurality of access modes to insert; Both can support WLAN to insert like this ASN, and also can support CDMA to insert, like Fig. 3.This moment is as long as two kinds of access waies of this equipment externally have two different RID and get final product.In this case, can think and support the ASN of different access waies physically uniting two into one.
For different access waies, during position that UE registers in ILR through ASN, the RID that every kind of access way is registered must be different, and ILR can distinguish the real ASN of every kind of access way like this.
In addition, adopt the plurality of access modes access network in order to support the user, the present invention also improves ILR, so that the user can register different AID and RID corresponding relation respectively for different access waies when adopting the plurality of access modes access network.
In initial SILSN, ILR is depositing the corresponding relation of RID of user's the ASN that AID and user terminal inserted, and this corresponding relation is man-to-man, that is to say that each AID has unique RID corresponding.
As: AID on the ILR of SILSN originally and RID corresponding relation are:
AID1-＞RID4
AID2-＞RID5
AID3-＞RID5
......
It is as shown in Figure 4 that above-mentioned corresponding relation can use graph-based.
Can find out; In original scheme, each AID has only a RID corresponding in ILR, like this when the user successively adopts the plurality of access modes access network; Will rewrite AID and RID corresponding relation among the ILR, therefore each user terminal can only be supported a kind of access way in this scheme.
For supporting that the user adopts the plurality of access modes access network; The present invention has also improved AID and the corresponding relation of RID among the ILR; The corresponding relation of AID and RID is related with access way; Make each AID can corresponding a plurality of RID, the user be when adopting the plurality of access modes access network like this, and a kind of access way just can not cover the AID and the RID corresponding relation of (rewriting) another kind of access way when location registers; Thereby ILR can write down the positional information of various access waies, guarantees that other users can call out this user smoothly.
For example, after the user supported multiple access, corresponding relation was following among the ILR:
AID1-＞RID4, access way 1 (=WLAN)
AID1-＞RID5, access way 2 (=GPRS)
AID1-＞RID8, access way 3 (=WCDMA)
AID2-＞RID7, access way 1 (=WLAN)
AID3-＞RID4, access way 1 (=WLAN)
AID3-＞RID2, access way 3 (=WCDMA)
......
The graph-based of corresponding relation is as shown in Figure 5 among the above-mentioned ILR.
Through adopting such scheme; In ILR; Each AID can have a plurality of RID corresponding with it, and every kind of access way can independently register the position of oneself, and the corresponding a kind of access way of RID; Thereby solved the problem that various access waies covered each other when the user adopted the plurality of access modes access network, and made the user adopt plurality of access modes can realize roaming.
When ILR can preserve many groups corresponding relation of an AID simultaneously; Can use same AID to communicate when inserting through plurality of access modes for the assurance user; Described the process of user equipment registration, cancellation and inquiry in the embodiments of the invention respectively, can not support the problem that same subscriber equipment uses multiple mode to insert to solve SILSN.
Embodiment one, customer location registration (being called Location Registration again) process
Under the scene that adopts the plurality of access modes access network, each user can insert in different places.For supporting moving of user, when customer location changes, need user's position be remodified.Phase mutual interference when avoiding the plurality of access modes registration location.When present embodiment passes through user equipment registration the user, carry the type of access way simultaneously, i.e. access style.As shown in Figure 6, the process of subscriber equipment in the present embodiment (UE1) registration comprises:
When step 201:UE1 is linked into new access server ASN1, at first initiate position register request to ASN1, this position register request is carried this user's access identifier AID1;
After step 202:ASN1 receives the position register request of UE1,, add in the position register request, and position register request is sent to ILR Route Distinguisher (also being routing address) RID1 and these two parameters of access style of this ASN1;
After step 203:ILR receives the position register request that ASN1 sends, extract AID1, in the retrieval local data base (being the database of this ILR) whether the data record of AID1 is arranged, if do not find relative recording, the data record of a then newly-built AID1; If find data record,, judge whether to have the User Identity of same access style and the corresponding relation of station location marker according to the access style in this position register request; Promptly under same access style; Whether the corresponding relation of AID1 and RID has been arranged,, then replaced original corresponding relation with the AID1 and the RID1 corresponding relation that carry in this position register request if having; If there is not corresponding relation; Then add AID1 related with this access style and the corresponding relation of RID1, then to ASN1 home position register response, this location registers response carries the successful result of location registers.
Step 204:ASN1 sends to UE1 through the location registers response with the result after receiving the location registers response that ILR sends, the location registers success.
In another embodiment, when the user need insert (being plurality of access modes) at a plurality of access servers, ASN only specified different access styles to get final product.Present embodiment is that example describes with two kinds of access waies, and in this case, the location registration of subscriber equipment is as shown in Figure 7, comprising:
Step 301: the user terminal UE1 with the WLAN access network initiates position register request; ASN1 finds that the AID1 of this UE1 is through the WLAN access network; Therefore the access style with this position register request is made as WLAN; And in this position register request, increase RID1, send position register request to ILR then.
