Corresponding, present invention provides a kind of IP Multimedia System, comprising: home subscriber server, at least one
Individual service call session control function entity, and the IP Multimedia System terminal that the present invention provides.
Embodiment three:
In conjunction with concrete application scenarios the present invention done and further annotate explanation.
The verification process that in 3GPP, UE accesses IMS is to realize based on IMS-AKA, and the present embodiment is also based on IMS-AKA certification
The present invention is done and further annotates explanation by mechanism.
In IMS system, CSCF (Call Session Control Function, CSCF) is IMS
Internal functional entity, is the core of whole IMS network, the signaling control during main responsible process multimedia call session
System.It manages the subscription authentication of IMS network, IMS loading end QoS, coordinates the control carrying out SIP session with other network entities,
And service negotiation and resource distribution etc..CSCF is divided into proxy CSCF (Proxy CSCF, P-CSCF) according to function, inquires about CSCF
(Interrogating CSCF, I-CSCF), serving CSCF (Serving CSCF, S-CSCF).
HSS (Home Subscriber Server, home subscriber server) is the important composition portion of key-course in IMS
Point, HSS supports to call/primary user data the storehouse of the IMS network entity of session for processing.It comprises user profile,
Perform authentication and the mandate of user, and the information of relevant user physical location can be provided.It is similar to GSM Home
Location Register, the entity communicating with HSS is application server (AS) and CSCF server
(CSCF), wherein application server with IMS environment as host and performs service therein.User profile comprises relevant current
The usual S-CSCF of information of user can the download and use this file when user carries out network registry.
IMS is IP Multimedia System, is a kind of brand-new multimedia service form, and it disclosure satisfy that present terminal visitor
Family is more novel, the demand of more diversified multimedia service, and IMS is considered as the core technology of next generation network.VoLTE(Voice
Over LTE), it is the speech business based on IMS, rather than based on traditional IP network (such as internet), framework is in operator
Network on, this means that operator can be that VoLTE provides the control of higher level and management.RCS(Rich
Communication Services), converged communication service.VoWiFi (Voice over WiFi) simply using WiFi as connecing
Networking, being finally intended to access IMS, it is the ip voice service that operator can control and manage.
AKA mechanism is to be formulated and used by 3GPP by IETF, is widely used in the authentication mechanism of 3G wireless network, the mirror of IMS
Power mechanism has continued to use principle and the core algorithm of this mechanism, therefore referred to as IMS-AKA is machine-processed.IMS AKA mechanism is to HTTP
The extension of digest authentication mechanism, is mainly used in the distribution of user authentication and session key, and its realization is based on a long-term shared
Key (KEY) and a sequence number (SQN), they are only visible in HSS and UE, owing to HSS does not directly communicate with UE, but by
S-CSCF performs this journey of certification, and therefore real KEY will not be exposed to the external world by them, and it implements process and repeats no more.
Now only this IMS AKA mechanism content related to the present invention is illustrated.
UE must register to IMS network before using IMS service, can complete UE to network by registration process
With the two-way authentication to UE for the network.The verification process that in 3GPP, UE accesses IMS is to realize based on IMS-AKA.In IMS-AKA, UE leads to
Cross message authentication code MAC and sequence number SQN and come the legitimacy of certification network and the freshness of key, and network passes through AKA certification
Response message RESP confirms the legitimacy of UE.Complete the two-way authentication between UE and network by such mechanism.
UE can select different authentication vector AV when carrying out IMS-AKA certification every time, so can ensure that every
CK and IK that secondary communication uses is calculated by different RAND (), and the MAC using every time is by being constantly incremented by
SQN, as one of input variable, ensures that the freshness of key.And at UE by calculating desired message authentication code MAC
Checking network is by after (think network illegal/service end is abnormal, terminates this time, scheduled time re-register), and UE will then examine
Look into sequence number SQN whether within the scope of correct, if the current sequence number SQN puing question to is more than using when puing question to last time
SQNi, then it is assumed that SQN is within the scope of correct, otherwise it is assumed that UE and network lock-out, now UE can calculate and re-synchronize parameter
Concurrently play re-register.
Existing IMS-AKA scheme use SQN ensure the freshness of key between UE and S-CSCF.At the beginning of IMS-AKA
In beginning registration process, first S-CSCF can apply for authentication vector AV from HSS, and HSS generates authentication according to AKA algorithm
Vector AV, (random parameter RAND, it is desirable to response XRES, the network comprising XMAC and the SQN value after encryption is recognized to comprise five elements
Card token AUTN, encryption key CK, integrality key IK), do not comprise SQN and shared key in plain text.But it is existing in reality
In order to improve the operating efficiency of S-CSCF in net, S-CSCF can apply for from HSS that many group AV authentication vectors are used for follow-up
Certification or re-authentication process, when UE is in registration, first S-CSCF can detect the corresponding AV authentication vector that self whether is stored with,
If had, being directly used in authentication, after the AV authentication vector of storage in S-CSCF all makes to be finished, it just can remove weight in HSS
New application.
In IMS multi-service application, there is a lot of business that IMS-AKA algorithm can be used to complete authentication process, right
There may be different S-CSCF in the different IMS business of same user is its service, and now each S-CSCF is respectively this user
Having applied for AV authentication vector, wherein the information of SQN necessarily has successively, and each IMS business carried in the last time of UE side storage when registration
The SQNi asking does not makes a distinction according to different business, arises that different IMS business SQN uses confusion to cause IMS business
The generation of frequent re-register.Increase network overhead, extend user's access delay, reduce Consumer's Experience.
It is exemplified below:
As a certain UE supports two kinds of IMS business of RCS and VoLTE, it all completes certification registration by IMS-AKA process, and
Network side different S-CSCF server for the two traffic assignments.Assume that VoLTE first registers, for the S-of VoLTE service
CSCF1 can be from HSS application many groups AV authentication vector, it is assumed that be 3 groups, corresponding SQN be respectively 00X002,00X003 and
00X004, S-CSCF1 use first group of AV to be authenticated, after VoLTE authentication registration passes through, and can be by message that SQN is 00X002
It is saved in UE.Initiating RCS registration afterwards, the S-CSCF2 for RCS service can be from HSS application many groups AV authentication vector, it is assumed that be also
3 groups, corresponding SQN is respectively 00X005,00X006 and 00X007, and S-CSCF2 uses first group of AV to be authenticated, and RCS registers
After certification is passed through, the SQN storing can be updated to 00X005 in UE.So problem is just come, and again initiates registration at VoLTE
When, arise that SQN step-out problem when being authenticated for second AV authentication vector that its S-CSCF1 servicing uses, cause
UE re-registers, until the AV authentication vector of application wants new in S-CSCF2 in S-CSCF1.
The present invention program provides the method and system of a kind of IMS terminal multi-service authentication registration.Mainly in UE side respectively
The new of each business cipher key is judged when SQN information when storing the success of each IMS service log-on is for correspondence service log-on certification next time
Fresh property, SQN information when effectively managing each service log-on certification, prevent multi-service SQN from using chaotic problem, the present invention program is only
In the modification of UE side, can effectively solve, owing to SQN uses confusion to cause the problem of re-register, to increase Consumer's Experience.
Concrete, the present invention program stores SQN information, each service log-on certification time-division safety pin respectively mainly for each business
The enquirement SQN information retrieving corresponding business last time to type of service from UE is verified, by new SQN information after being verified
It is saved in corresponding business, use form or each IMS business storing in the way of modification SQN naming rule corresponding
SQN information.
