Problems solved by technology

[0006] As stipulated in the protocol, when the authentication method is the Digest method, only one set of authentication vectors can be downloaded, so every time the user terminal needs authentication during the use of multimedia services, the S-CSCF must interact with the HSS to obtain the authentication Vector authentication, resulting in low authentication efficiency

Embodiment 1

[0025] An embodiment of the present invention provides an authentication method, which is applicable to the case of performing service authentication on a UE (User Equipment, user terminal), such as figure 2 As shown, the authentication method includes the following steps S201-S202.

[0026] Step S201, S-CSCF (Serving Call Session Control Function, service call session control function) receives the registration request sent by UE, and performs registration authentication with HSS (Home Subscriber Server, Home Subscriber Service); if the registration authentication is successful, then S-CSCF saves the authentication vector.

[0027] In this step, after receiving the registration request sent by the UE, the S-CSCF performs MAR (Multimedia authorization request, multimedia authentication request) / MAA (Multimedia authorization answer, multimedia authentication response) interaction with the HSS, and obtains authentication from the MAA fed back by the HSS Vector H(A1). The auth...

Embodiment 2

[0032] The embodiment of the present invention provides an authentication method, which is applicable to the case where the S-CSCF performs registration service authentication on the UE, such as image 3 As shown, it specifically includes the following steps S301-S306:

[0033] In step S301, the S-CSCF receives the first registration request sent by the UE, sends a multimedia authentication request MAR to the HSS, and receives a multimedia authentication response MAA fed back by the HSS.

[0034] In this step, after receiving the MAR sent by the S-CSCF, the HSS calculates and obtains the authentication vector according to the PVI, key and realm value, and fills the authentication vector into the MAA and feeds it back to the S-CSCF.

[0035] In step S302, the S-CSCF obtains the authentication vector from the MAA, and feeds back a response message containing the authentication vector to the UE.

[0036]In this step, the S-CSCF extracts the authentication vector in the MAA, gene...

Embodiment 3

[0047] The embodiment of the present invention provides an authentication method, which is applicable to the case where the S-CSCF performs re-registration or deregistration service authentication on the UE, such as Figure 4 As shown, it specifically includes the following steps S401-S411:

[0048] In step S401, the S-CSCF receives the first re-registration or deregistration request sent by the UE.

[0049] Step S402, judging whether there is an authentication vector stored in the S-CSCF; if no authentication vector is stored, perform step S403; if there is an authentication vector, perform step S404.

[0050] In step S403, the S-CSCF performs MAR / MAA interaction with the HSS to obtain an authentication vector.

[0051] In step S404, the S-CSCF feeds back a response message including the authentication vector to the UE.

[0052] Step S405, the S-CSCF receives the second re-registration or deregistration request sent by the UE, wherein the second re-registration or deregistr...

Abstract

The invention provides an authentication method and device. The method comprises the steps that an S-CSCF receives a registration request sent by a UE, and carries out registration authentication with an HSS; if the registration authentication is successful, then an authentication vector is saved by the S-CSCF; a reregistration request or an unregistration request sent by the UE is received by the S-CSCF, it is judged that whether the authentication vector is saved in the S-CSCF or not, and if the authentication vector is saved, then reregistration authentication or unregistration authentication is carried out on the UE based on the authentication vector. According to the method and device, the registration request sent by the UE is received by the S-CSCF, if the registration authentication is successful, then the authentication vector and user data are saved by the S-CSCF; when the reregistration request or the unregistration request sent by the UE is received by the S-CSCF, and if the authentication vector is saved in the S-CSCF, then reregistration authentication or unregistration authentication is carried out on the UE based on the authentication vector, the authentication vector not longer needs to be acquired by interacting with the HSS, and therefore the efficiency for reregistration authentication or unregistration authentication is improved.

Description

technical field [0001] The invention relates to the communication field, in particular to an authentication method and device. Background technique [0002] The IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) can provide a brand-new form of multimedia service, and can meet users' requirements for more novel and diversified multimedia services. [0003] The network element entities of the IMS include: UE (User Equipment, user terminal), S-CSCF (Serving Call Session Control Function, serving call session control function), and HSS (Home Subscriber Server, home subscriber service). Among them, the S-CSCF is the core part of the IMS, responsible for user terminal registration, authentication, service triggering and session control functions, and the HSS is the server for storing user and server related information in the IMS. In order to ensure the security of the user account, before the user terminal runs the multimedia service, the IMS needs to authenticate the reques...
