Abstract

The invention discloses a registration processing method and an access processing method. The registration processing method comprises the following steps: when the high-speed packet data service gateway (HSGW) judges that the current registration of the terminal is in the pre-registration switching state, the HSGW notifies the home subscriber server/authentication authority accounting server (HSS/AAA) that the current registration of the terminal is in the pre-registration state, wherein the HSS/AAA acquiesces that the terminal access is single registration when not receiving the pre-registration notice; and the HSS/AAA stores the access network information of the terminal carrying out the double-registration, wherein the access network of the double-registration comprises an access network in which the terminal originally registered, and an access network by which the terminal switches the pre-registration. The invention can prevent the HSS/AAA from storing lots of redundant access network information, notifying redundant access network information update and mistakenly discarding useful redundant access network information, thereby saving the storage space of the HSS/AAA and reducing the transmission of the signaling.

Below in conjunction with some the basic signalling interactive process under the above-mentioned network architecture of concrete scene description.

Scene 1

Interconnect (the Connectivity andInterworking) of EPS network support and HRPD network, the intercommunication framework can be with reference to figure 2, wherein, in the framework that interconnects, thereby the HRPD technology has upgraded to eHRPD to be reached and the unified purpose of EPS network element, rename as HRPD gateway (HRPD ServingGateway behind the PDSN function upgrading, abbreviate HSGW as) (corresponding to the IAD among Fig. 1/Access Network control network element 2), HRPD-AN can be called the HRPD Access Network (evolved Access Network abbreviates HRPD-eAN as) of evolution behind function upgrading.

In addition, Fig. 2 also shows the S1-MME interface between eNode B and the MME, S6a interface between MME and the HSS, Wx* interface between HSS and the 3GPP aaa server, Ta* interface between 3GPP aaa server and the 3GPP2 aaa server, S11 interface between MME and the S-GW, S5 interface between S-GW and the P-GW, SGi interface between P-GW and the IP network, S6b interface between P-GW and the 3GPP aaa server, H1/H2 between HSGW and the eAN, the A10/A11 interface, A13/A16 interface between eAN and the UE, the function of these interfaces is existing definition in relevant criterion, and this paper is not described in detail.

In this intercommunication scene, data anchor point P-GW, no matter current terminal is to insert or insert by the eHRPD Access Network by the E-UTRAN Access Network, the up-downgoing transfer of data must be passed through data gateway P-GW.The continuity of business has increased some interfaces newly in order to realize the purpose that multimode terminal inserts by different connecting system and guarantee enough that simultaneously terminal is switched in different access systems, that is, and and S101 interface, S103 interface and S2a interface.Wherein, the S101 interface is used for terminal transmission pre-registration signaling and hand off signaling when E-UTRAN and the switching of eHRPD system; The S103 interface is used for terminal by E-UTRAN system converting downlink data when the eHRPD system is switched.The S2a interface transmits control and bearer service between HSGW and P-GW, adopt the PMIPv6 agreement.

At present, subscriber equipment (User Equipment, abbreviate UE as) (promptly, terminal) mainly comprise to the step that the eHRPD connecting system switches from the E-UTRAN connecting system: UE detects current E-UTRAN wireless signal and begins to become more weak, the wireless signal of eHRPD is fine, UE is before formally switching to eHRPD, doing pre-registration to the eHRPD system earlier prepares, because terminal is singly to treat terminal (being that terminal can not be opened multiple standard wireless transmission and reception simultaneously), (analysis of existing procedure is seen below in concrete operations) that the eHRPD signaling of this pre-registration stage is delivered to HRPD-eAN and HSGW through the wireless signal and the S101 interface of encapsulation by E-UTRAN.And, have only when UE detects current E-UTRAN signal and can not support under the situation of current business, just formally switch to the eHRPD system.

The concrete operations of switching can be with reference to Fig. 3, and concrete switching flow is as follows:

301, UE is linked into EPC by E-UTRAN, and is in activation (Active) state;

302, UE is by measuring wireless signal, and it is more weak to detect current E-UTRAN wireless signal, and the wireless signal of eHRPD is fine, and decision UE does pre-registration to the eHRPD system and prepares; And set up eHRPD session, bottom data passage etc.;

Below be access authentication from step 303 to 307, be divided into following a few step in the flow process to realize so that careful description.

303, UE initiates to insert the EAP authentication and authorization of eHRPD system, and sends a message to HSGW;

304, HSGW sends DER (the Diameter extended authentication agreement request) message of AAA authentication signaling and gives 3GPP AAA/HSS, carry user's identification information in the signaling, parameters such as Access Network information, signaling may be passed through 3GPP2 AAA in transmission course, forwarding and the transmission of the 3GPP AAA on visit ground;

305, the information that 3GPP AAA/HSS sends according to UE, Access Network is calculated Ciphering Key and key according to authentication arithmetic;

306,3GPP AAA/HSS returns authentication information to HSGW; Signaling may be passed through 3GPP2AAA in transmission course, forwarding and the transmission of the 3GPP AAA on visit ground;

307, the remaining step of authentication operations is finished authentication;

308, set up PDN between UE and the HSGW and connect, reserved resource and foundation carrying; Therefore this flow process is the pre-registration flow process, has difference with the access process of reality, is mainly reflected in also not binding between HSGW and the anchor gateway;

309, after 308 steps, UE may not switch to the eHRPD system immediately, has only the signal that detects E-UTRAN as UE to be not enough to support current when professional, and UE just formally switches to eHRPD from E-UTRAN.

In the above flow process, between 308 steps and 309 steps, may there be the long time interval (length in this time interval is uncertain), so during this time interval, UE is two registrations to core net.

Scene 2

As shown in Figure 4, UE is under the covering that non-3GPP and 3GPP insert simultaneously, and UE is double-mode and double-standby terminal, is linked into PDN by non-3GPP IP Access Network and 3GPP Access Network and via same P-GW.Under this scene, P-GW can distribute an IP address for UE,, has only an IP-CAN session between UE and the PDN that is.P-GW or PCRF can send to UE by which Access Network according to the different qualities decision IP traffic of business.In addition, PCRF also needs and P-GW, and non-3 GPP access network and 3GPP access interaction carry out policy and charging control.

Fig. 5 and Fig. 6 show the detailed process of switching in this scene.

Fig. 5 shows the signaling process that adheres to core net from the 3GPP Access Network after UE inserts non-3 GPP access network, as shown in Figure 5, specifically comprise following processing:

501, UE is linked into the EPC system by non-3 GPP access network, and has relevant business and transmit in this connection, wherein, non-3 GPP access network close and P-GW between carry out tunnel binding;

502, the UE transmission is adhered to demand signalling and is arrived MME by eNB;

503, UE finishes from the access authentication of 3GPP Access Network and mandate;

504, after the successful authentication, MME obtains demand signalling to HSS transmission position renewal and strategy;

505, HSS answers the response signaling to MME;

506, MME sends " creating the default bearing request " signaling to S-GW;

507, S-GW sends " creating the default bearing request " signaling and gives P-GW;

508, P-GW responds the establishment default bearing to S-GW and replys signaling, has set up new tunnel between S-GW and the P-GW;

509, S-GW responds the establishment default bearing to MME and replys signaling;

510, S-GW responds to adhere to UE and replys signaling, finishes adhering to from the 3GPP Access Network.

Fig. 6 shows the signaling process that adheres to core net from non-3 GPP access network after UE inserts the 3GPP Access Network, as shown in Figure 6, specifically comprise following processing:

601, UE is linked into the EPC system by the 3GPP Access Network, and has relevant business and transmit in this connection, wherein, and tunnel binding between S-GW and the P-GW;

602, UE and non-3 GPP access network close carries out the link establishment operation of eating dishes without rice or wine of specific non-3 GPP access network;

Below be access authentication from step 603 to 607, be divided into following a few step in the flow process to realize so that careful description.

603, UE initiates to insert the EAP authentication and authorization of non-3 GPP system, and sends a message to the non-3 GPP access network pass;

604, non-3 GPP access network closes DER (the Diameter extended authentication agreement request) message that sends AAA authentication signaling gives AAA/HSS, carry user's identification information in the signaling, parameters such as Access Network information, signaling may be passed through forwarding and the transmission of the AAA on visit ground in transmission course;

605, the information that AAA/HSS sends according to UE, Access Network is calculated Ciphering Key and key according to authentication arithmetic;

606, AAA/HSS closes to non-3 GPP access network and returns authentication information; Signaling may be passed through forwarding and the transmission of the AAA on visit ground in transmission course;

607, the remaining step of authentication operations is finished authentication;

608, UE initiates to adhere to request to non-3 GPP access network according to its specific mode;

609, non-3 GPP access network close receive that UE sends adhere to request after, initiate tunnel binding demand signalling to P-GW;

610, P-GW upgrades its address information to AAA/HSS;

611, P-GW closes to non-3 GPP access network and responds tunnel binding request-reply signaling;

612, non-3 GPP access network closes to the UE response replys signaling distinctive adhering to of non-3 GPP access network, and notice UE finishes in the attachment flow of non-3 GPP access network.

By above flow process as can be seen, no matter be E-UTRAN and eHRPD interconnect pre-registration under the scene, or multiple access scene, all need to be registered to simultaneously core net, and need carry out authentication and position renewal to 3GPP AAA/HSS.

But based on existing single operation that inserts, under different occasions, because the specific implementation difference of network, the operation of AAA/HSS also may be inequality.The information of the Access Network of preserving for AAA/HSS, mainly have following two kinds of processing modes: (mode one) AAA/HSS can store last arrival AAA/HSS updated information content, and think that this canned data is the Access Network information of current UE, and the information of deleting original Access Network; (mode two) has the updated information to AAA/HSS as long as AAA/HSS can give tacit consent to, and the content that this message will be carried is stored, and do not delete the information of original Access Network.

But in two registration scenes (described before scene 1 and scene 2), no matter any in the above dual mode all can go wrong, and be specific as follows:

If AAA/HSS only keeps the information (adopting aforesaid way one) of a Access Network, in case receive the information of just deleting original Access Network after the updating message, then in multiple access scene (more than enumerate scene 1 and 2), HSS/AAA just can't keep the information of original Access Network, thereby cause when AAA/HSS has user's CAMEL-Subscription-Information to change, AAA/HSS can't notify the change of CAMEL-Subscription-Information the pairing Access Network of access information of deletion, causes information to leak and sends out; And when Access Network information has change, can oppositely override the information of the Access Network of original HSS/AAA storage again;

If adopt above-mentioned mode two, promptly, as long as the updated information to AAA/HSS is arranged, the content that AAA/HSS will carry this message is stored, do not delete the information (information that can keep two parts of Access Networks at this moment of original Access Network, corresponding to two Access Networks), if carried out single access this moment, then can cause AAA/HSS to store the information of bulk redundancy, if and AAA/HSS in information change, will send corresponding notification message to a plurality of Access Networks, if this moment UE from certain Access Network attachment removal (at this moment, UE does not need the relevant information of this attachment removal Access Network), will cause the waste of signaling.

At exist in the correlation technique because AAA/HSS storage bulk redundancy information and send the problem that the useless memory space that notification message caused takies with fullying in a large number and signaling is wasted does not propose effective solution at present as yet.

Functional overview

At taking in a large number fully of existing in the correlation technique owing to HSS/AAA stores bulk redundancy information and sends the useless memory space that notification message caused, and the problem of signaling waste, the present invention proposes to be provided with the UE access way of HSS/AAA acquiescence, do not having under the situation about notifying in addition, HSS/AAA will preserve or delete the information of the Access Network of UE according to the access way of this acquiescence, if the access way of UE reality is different with the mode of this acquiescence, then the access way with UE reality is notified to HSS/AAA, so that HSS/AAA preserves or abandon the information of the Access Network of UE according to the access way of notice.Like this, HSS/AAA neither can store the information of unnecessary in a large number Access Network, also can not abandon the information of the Access Network of multiple access (two registration) mistakenly, efficiently solves the problem in the correlation technique.

Below in conjunction with instantiation technical scheme of the present invention is described.

Method embodiment one

In the present embodiment, provide a kind of registration handling method, be applied to the situation that E-UTRAN and eHRPD interconnect.

Fig. 7 is the flow chart according to the registration handling method of present embodiment, need to prove, the step of describing in following method can be carried out in the computer system such as a set of computer-executable instructions, and, though figure 7 illustrates logical order, but in some cases, can carry out step shown or that describe with the order that is different from herein.

As shown in Figure 7, the method according to present embodiment comprises following processing:

Step S702, under the current situation that is registered as pre-registration that HSGW judges terminal, HSGW notice HSS/AAA terminal current is registered as switches pre-registration (this moment, terminal was carried out two registrations, and terminal might insert the Access Network of this pre-registration afterwards), wherein, the access of HSS/AAA acquiescence terminal under the situation of not receiving the pre-registration notice is single registration;

Step S704, HSS/AAA preserves the information that terminal is carried out the Access Network of two registrations, and wherein, the Access Network of two registrations comprises the Access Network of the former registration of terminal and the Access Network that terminal inserts pre-registration.

Described in this article pre-registration is meant: in terminal under the situation of Access Network 1 registration, this terminal can be initiated registration to Access Network 2 by this Access Network 1, promptly, pre-registration, the initiation process of this registration can't disconnected end and being connected of Access Network 1, and this terminal can utilize the information that is notified to Access Network 2 in the pre-registration process to switch to (being linked into) Access Network 2.

In above-mentioned processing, HSGW can be by the authentication signaling (preferably, can be Diameter extended authentication agreement request (the abbreviating DER as) message in the authentication signaling) the pre-registration indication is sent to HSS/AAA, wherein, the pre-registration indication is used to represent the current pre-registration that is registered as of terminal.

Alternatively, the indication of above-mentioned pre-registration can be the authentication signaling (preferably, can be Diameter extended authentication agreement request (the abbreviating DER as) message in the authentication signaling) in one or more fields, also can be one or more parameters, when HSS/AAA receives this indication, just can preserve the information of a plurality of Access Networks of terminal.

Below in conjunction with the processing of instantiation 1 description according to present embodiment.

Example 1

The scene of the pre-registration of UE in the eHRPD system has been described in this example.Wherein, UE inserts in the EPS system, afterwards owing to reasons such as signal strength signal intensities, the possibility of moving to the eHRPD system is arranged, then in the eHRPD system, done the pre-registration of layer three by the wireless signal of E-UTRAN, like this, concerning core net, UE has done two registrations in dual system.HSGW passes through in the authentication signaling (preferably, can be Diameter extended authentication agreement request (the abbreviating DER as) message in the authentication signaling) in carry " pre-registration " indication to notify HSS/AAA current be the pre-registration scene, and notify it to distinguish single registration scene, and the information of storing two parts of Access Networks.

As shown in Figure 8, concrete processing procedure is as follows:

801, UE is linked into EPC by E-UTRAN, and is in activation (Active) state;

802, UE is by measuring wireless signal, and it is more weak to detect current E-UTRAN wireless signal, and the wireless signal of eHRPD is fine, and decision UE does pre-registration to the eHRPD system and prepares; And set up eHRPD session, bottom data passage etc.;

Below be access authentication from step 803 to 807, be divided into following a few step in the flow process to realize so that careful description.

803, UE initiate to insert the EAP authentication and authorization of eHRPD system, and sends a message to HSGW, and what HSGW judged that the user carries out is pre-registration;

804, HSGW sends the DER message of AAA authentication signaling to 3GPPHSS/AAA, carries user's identification information in the signaling, parameters such as Access Network information; Wherein, the designator of pre-registration is announced to HSS/AAA by this signaling.Signaling may be passed through 3GPP2 AAA in transmission course, forwarding and the transmission of the 3GPP AAA on visit ground;

805, the information that 3GPP HSS/AAA sends according to UE, Access Network is calculated Ciphering Key and key according to authentication arithmetic;

At this moment, 3GPP HSS/AAA is according to the pre-registration designator, judge that current is the pre-registration scene, but not initially insert or handoff scenario, therefore HSS/AAA preserves outside the information of eHRPD system, but do not delete the identification information of EPS system, HSS/AAA has stored the information of two parts of Access Networks like this, and this inserts with single registration/list is different.

806,3GPP HSS/AAA returns authentication information to HSGW; Signaling may be passed through 3GPP2AAA in transmission course, forwarding and the transmission of the 3GPP AAA on visit ground.

807, the remaining step of authentication operations is finished authentication.

808, set up PDN between UE and the HSGW and connect, reserved resource and foundation carrying; Therefore this flow process is the pre-registration flow process, has difference with the access process of reality, is mainly reflected in also not binding between HSGW and the anchor gateway.

809, after 808 steps, UE may not switch to the eHRPD system immediately, has only the signal that detects E-UTRAN as UE to be not enough to support current when professional, and UE just formally switches to eHRPD from E-UTRAN.

By processing according to present embodiment, make that HSS/AAA can only preserve the information of an Access Network under the situation that does not have the pre-registration indication, avoided the preservation of redundant information and the notice that in the future useless Access Network upgrades; Under the situation that the pre-registration indication is arranged, HSS/AAA can preserve the information of two Access Networks, avoids deleting mistakenly required Access Network information.

That is to say, change that just can distinguish is singly to insert but register scene or multiple access is registered scene more, can not leak a data if user signing contract information appears in HSS/AAA; If when upgrading information change appearred and arrive HSS/AAA in Access Network, HSS/AAA can not delete original information yet, has caused information dropout by mistake.

Method embodiment two

In the present embodiment, provide a kind of registration handling method, be applied to the situation that E-UTRAN and eHRPD interconnect.Different with the method described in the method embodiment one, in the described method of present embodiment, the current access of HSS/AAA acquiescence terminal is a multiple access, like this, when HSS/AAA receives the notice of single registration, will only preserve the information of a Access Network.

Fig. 9 is the flow chart according to the registration handling method of present embodiment, need to prove, the step of describing in following method can be carried out in the computer system such as a set of computer-executable instructions, and, though figure 9 illustrates logical order, but in some cases, can carry out step shown or that describe with the order that is different from herein.
