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, the method for one kind of multiple access way access networks particularly related to, access device and authenticating device.
Background technology
Existing internet widely used transmission control protocol/Internet Protocol (TransmissionControl Protocol/Internet Protocol, TCP/IP) in, 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.The situation of host mobility is not considered at the beginning of TCP/IP design.But when host mobility is more and more general, the semanteme overload defect of IP address is day by day obvious.When the IP address of main frame changes, not only route will change, and the identify label of communication terminal main frame also changes, thus routing overhead can be caused more and more heavier, and the change of host identification can cause application and the interruption be connected.The object that identify label is separated with station location marker be in order to solve IP address in TCP/IP semanteme overload and routing overhead serious, and the problem such as fail safe, thus the dual-use function of IP address is separated, realize mobility, many locals property, the dynamic code reassignment in IP address, alleviate the support of the problems such as exchanging visit in routing overhead and Next Generation Internet between heterogeneous networks region.
For solving the problem, propose the network architecture that multiple identify label is separated with station location marker at present, comprise host identity protocol (Host Identity Protocol, HIP), location identity separated protocol (LISP), all genus identify label and locator separation network.
(application number is the Chinese patent application of CN200910174826.9 for identify label shown in Fig. 1 and locator separation network framework, the applying date is on October 17th, 2009), for convenience of description, hereafter by this User Identity and locator separation network referred to as SILSN (Subscriber Identifier & LocatorSeparation Network); SILSN comprises access server (Access Service Node, ASN), subscriber equipment (User Equipment, and identify label and location register register (Identification & Locater Register, ILR) etc. UE).Wherein ASN is used for access user equipment, is responsible for the access realizing subscriber equipment, and bears the function such as charging and switching, and ILR bears position registration and the identity recognition function of user.Wherein, ASN is logic entity, can be service universal packet wireless business business (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, and the equipment such as BAS Broadband Access Server (Broadband RemoteAccess Server, BRAS) PDSN).Above-mentioned ILR can be key management system (Key Management System in embody rule scene, KMS), attaching position register (Home LocationRegister, HLR), home subscriber server (Home Subscriber Server, HSS), mandate/certification/accounting server (Authorization, Authentication, Accounting, AAA) and other bear the entity of end-to-end key management and negotiation functionality.
In SILSN, user is to access identifier (Access Identification, AID) (identity for identifying user) is identified, ASN is with Route Distinguisher (Route Identification, RID) identify (position for identifying user place), each user and ASN have oneself independently AID or RID.When the user of in SILSN (as UE1) access network, first register its position (namely register this UE1 be positioned at which ASN under) by ASN to ILR.ILR after UE1 registration, the AID setting up user and the corresponding relation of the RID of ASN accessed.If UE1 needs and UE2 communication afterwards, after UE1 sends data message, inquired about the position of UE2 to ILR by ASN1, under namely which ASN UE2 is positioned at, under UE2 is positioned at ASN9 in Fig. 1.Then data message is sent to corresponding ASN9 by ASN1, and the data message after process is sent to UE2 by ASN9 again.
Above-mentioned network well achieves the identify label of user and being separated of station location marker, when subscriber equipment moves and roams, does not need to change identify label again, ensure that the continuity of business in moving process.Routing expansion and fail safe also significantly improve.
In initial SILSN, each subscriber equipment can only access network in one way.But recent years, people start to get used to utilizing various ways access network gradually, if any subscriber equipment can adopt Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access simultaneously, and WLAN (wireless local area network) (Wireless Local Area Network WCDMA), the mode access network such as WLAN), to make full use of the network bandwidth, this proposes new demand to the SILSN being originally designed to single access way.
For in existing SILSN: SILSN does not design for plurality of access modes.Therefore, when subscriber equipment adopts plurality of access modes access network, just can only distribute a different AID for often kind of access way of each subscriber equipment, be equivalent to same subscriber equipment and employ different access identifier accesses, run counter to the user's request of access identifier uniqueness.
Simultaneously, same subscriber equipment has different identify labels, the maximum bandwidth using plurality of access modes cannot be merged when subscriber equipment is linked in network by plurality of access modes, when an access link interrupts, the link of another one access can not be seamlessly switched to.In addition, be the behavior of a subscriber equipment originally, but showed as multiple access identifier, and be unfavorable for that state security department monitors user and traces to the source, have impact on the fail safe of network.

Embodiment
In the network that identify label is separated with station location marker, each user has two identifiers, that is: AID and RID, wherein the identity of AID representative of consumer, the position of RID representative of consumer.When user adopts plurality of access modes access network, in order to keep the uniqueness of user identity AID, AID must remain unchanged, and so just only has by RID to distinguish each access way of user.
The invention provides the method for a kind of user by plurality of access modes access network, be applied to the network that identify label is separated with station location marker, the method comprises: the user terminal with the identify label of same user adopts plurality of access modes access network by one or more access nodes with diverse location mark, wherein, described access way and described station location marker one_to_one corresponding, described plurality of access modes corresponds to the same identify label of described user.
Wherein, access node has one or more station location marker;
When user terminal adopts plurality of access modes access network by an access node with diverse location mark, described access node has multiple station location marker, often kind of corresponding station location marker of access way;
When user terminal adopts plurality of access modes access network by multiple access nodes with diverse location mark, each access node has a station location marker, the station location marker of often kind of corresponding access node of access way; Or
When user terminal adopts plurality of access modes access network by multiple access nodes with diverse location mark, access node has one or more station location marker, often kind of corresponding station location marker of access way.
Access way in the present invention comprises: WLAN (wireless local area network) (WLAN), GPRS (GPRS), Wideband Code Division Multiple Access (WCDMA) (WCDMA), TD SDMA (TimeDivision-Synchronous Code Division Multiple Access, TD-SCDMA), point-to-point protocol (Point-to-Point Protocol over Ethernet on Ethernet, PPPoE), , micro-wave access global inter communication (Worldwide Interoperability for Microwave Access, WiMAX), Long Term Evolution (LTE), one or more in CDMA2000 access way.
Hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combination in any mutually.In embodiments of the invention, be described for SILSN, but the present invention is not limited to this, the network that other identify labels are separated with station location marker can be applied to equally.
For distinguishing the plurality of access modes of same user, when user same in SILSN adopts plurality of access modes access network, single AID can be used as access mark (namely identifying unique AID of this user identity), but support that the access server of different access way has different RID.Namely different access waies must be registered under different ASN, or different access waies is by having the same ASN registration of different RID.More precisely, be exactly same user when adopting the access of different access way, the ASN accessed must possess different RID, access way and RID one_to_one corresponding.
For ensureing that user can adopt different access waies normally to access, in a kind of technical scheme provided by the invention, different access waies can only access different access servers, more strictly speaking, is that plurality of access modes can not access the access server with same RID address.As shown in Figure 2, when user adopts WLAN by UE1, code division multiple access (Code Division Multiple Access, CDMA) and WCDMA tri-kinds of access way access networks time, three kinds of access waies have accessed ASN1, ASN2 and ASN3 respectively, thus realize by plurality of access modes access network.
In another kind of technical scheme, in actual deployment, user by subscriber equipment access somewhere operator time, certain ASN of this operator can support to adopt plurality of access modes to access simultaneously, as this ASN both can support that WLAN accessed, also can support that CDMA accessed, as Fig. 3.As long as now two kinds of access waies of this equipment, externally have two different RID.In this case, can think and support that the ASN of different access way can unite two into one physically.
For different access waies, during the position that UE is registered in ILR by ASN, the RID that often kind of access way is registered must be different, and such ILR can distinguish the real ASN of often kind of access way.
In addition, in order to support that user adopts plurality of access modes access network, the present invention also improves ILR, to make user when employing plurality of access modes access network, can register different AID and RID corresponding relations respectively for different access waies.
In initial SILSN, ILR deposits the corresponding relation of the RID of the ASN that the AID of user and user terminal access, and this corresponding relation is man-to-man, and that is, each AID, has unique RID corresponding.
As: AID and the RID corresponding relation on the ILR of SILSN is originally:
AID1-＞RID4
AID2-＞RID5
AID3-＞RID5
Above-mentioned corresponding relation can be as shown in Figure 4 with graph-based.
Can find out, in original scheme, each AID only has a RID corresponding in ILR, like this when user successively adopts plurality of access modes access network, will rewrite AID and the RID corresponding relation in ILR, therefore in this scheme, each user terminal can only support a kind of access way.
For supporting that user adopts plurality of access modes access network, invention also improves the corresponding relation of AID and RID in ILR, the corresponding relation of AID with RID is associated with access way, make each AID can corresponding multiple RID, such user is when adopting plurality of access modes access network, a kind of access way would not cover AID and the RID corresponding relation of (rewriting) another kind of access way when location register, thus ILR can record the positional information of various access way, ensure that other users can call out this user smoothly.
Such as, after the multiple access of User support, in ILR, corresponding relation is as follows:
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)
In above-mentioned ILR, the graph-based of corresponding relation as shown in Figure 5.
By adopting such scheme, in ILR, each AID can have multiple RID corresponding with it, and often kind of access way independently can register the position of oneself, and a corresponding a kind of access way of RID, thus solve the problem that when user adopts plurality of access modes access network, various access way covers mutually, and user is made to adopt plurality of access modes can realize roaming.
When ILR can preserve many groups corresponding relation of an AID simultaneously, for same AID being used to communicate when ensureing that user is accessed by plurality of access modes, respectively describe the process of user equipment registration, cancellation and inquiry in embodiments of the invention, can not support that same subscriber equipment uses the problem of various ways access to solve SILSN.
Embodiment one, customer location registration (being also called position registration) process
Under the scene adopting plurality of access modes access network, each user can access in different places.For supporting the movement of user, when customer location changes, need to remodify the position of user.For avoiding mutually disturbing during plurality of access modes registration location.The present embodiment, when user is by user equipment registration, carries the type of access way, i.e. access style simultaneously.As shown in Figure 6, the process that in the present embodiment, subscriber equipment (UE1) is registered comprises:
When step 201:UE1 is linked into new access server ASN1, first to ASN1 launch position registration request, this position register request carries the access identifier AID1 of this user;
After step 202:ASN1 receives the position register request of UE1, by Route Distinguisher (being also the routing address) RID1 of this ASN1 and these two parameters of access style, add in position register request, and position register request is sent to ILR;
After step 203:ILR receives the position register request that ASN1 sends, extract AID1, in retrieval local data base (i.e. the database of this ILR), whether have the data record of AID1, if do not find relative recording, then the data record of a newly-built AID1, if find data record, according to the access style in this position register request, judge whether have the User Identity of same access style and the corresponding relation of station location marker, namely under same access style, whether there is the corresponding relation of AID1 and RID, if had, then replace original corresponding relation with AID1 and the RID1 corresponding relation carried in this position register request, if there is no corresponding relation, then add the corresponding relation of AID1 and RID1 associated with this access style, then to ASN1 home position register response, the response of this location register carries the successful result of location register.
Result is sent to UE1 by location register response after receiving the location register response that ILR sends by step 204:ASN1, location register success.
In another embodiment, when user needs to carry out accessing (i.e. plurality of access modes) at multiple access server, ASN only specifies different access styles.The present embodiment is described for two kinds of access waies, and in this case, the location registration of subscriber equipment as shown in Figure 7, comprising:
Step 301: with the user terminal UE1 launch position registration request of WLAN access network, ASN1 finds that the AID1 of this UE1 is by WLAN access network, therefore the access style of this position register request is set to WLAN, and RID1 is increased in this position register request, then send position register request to ILR.
When step 302:ILR receives the position register request that ASN1 sends, judge whether there is AID1 in local data base with the position record of WLAN access network, if had, by the corresponding relation of original AID1 and RID, change the corresponding relation of current AID1 and RID1 into.If the position record not having user AID1 to access with WLAN in database, then newly increase the corresponding relation of AID1 and RID1 associated with WLAN.
Step 303 ~ 304:ILR and ASN1 returns to ASN1 and UE1 location register response respectively, includes location register result in the response of this location register.
Step 305: with the user terminal UE1 of GPRS access to ASN1 launch position registration request, ASN1 finds that this AID1 is accessed by GPRS, therefore change this position register request access style into GPRS, and increase the RID1 of this access server, then to ILR launch position registration request.
