Problems solved by technology

According to the current protocol specification, in the process of UE's first registration, the S-CSCF needs to apply for the authentication quintuple to the HSS through the MAR / MAA message. In the case of quintuples, the step of S-CSCF to apply for authentication quintuples through MAR / MAA is obviously redundant, and, due to the additional message interaction in this step, when the user capacity is large, it will inevitably affect the entire system UE registration service efficiency

Embodiment Construction

[0052] When the UE (user equipment) registration status is Unregistered, the S-CSCF (serving call session control function) still saves data related to the UE, which includes: in the previous registration process of the UE, the S-CSCF applied for the UE If the authentication information stored in the S-CSCF can be fully utilized to authenticate the UE, it can effectively avoid S-CSCF The CSCF obtains the authentication information used for UE authentication from the HSS, thereby reducing the message interaction in the UE authentication process, and ultimately improving the UE authentication efficiency.

[0053] Therefore, in the present invention, when the UE initiates the first registration process, that is, during the UE initiates the first authentication process, if the registration status of the UE is Unregistered (non-registered business status), and the S-CSCF itself stores authentication information, the S-CSCF can no longer obtain UE-related authentication information ...

Abstract

The invention discloses an identifying weight method, device and system of IBM network, which comprises the following steps: using identifying weight information for UE identifying weight using which saves by S-CSCF itself; finishing UE and IMS network identifying weight processing procedure; registrating UE whose registration state is Unregistered and S-CSCF saves identifying weight information; providing dentifying weight scheme accomplish flow process of UE application identifying weight quintuple which can neglect S-CSCF and flow to HSS through MAR, MAA. The invention reduces MAR, MAA information source commutation, which optimizes identifying weight flow path of UE first registration.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to an authentication method, an authentication device and an authentication system in an IMS network. Background technique [0002] IMS (IP Multimedia Subsystem, IP Multimedia Subsystem) newly introduces two user identities, IMPI (IMS Private Identity, IMS Private Identity) and IMPU (IMS Public Identity, IMS Public Identity). IMPI is the private identity of IMS users, used to identify UE, and one-to-one correspondence with UE; IMPU is the public identifier of IMS users, which is used to identify a symbol for communication with each other, which is equivalent to a phone number. [0003] IMS authentication follows the two-way authentication method of WCDMAR4, that is, IMS authentication not only includes the verification of the validity of the terminal by the network, but also includes the verification process of the validity of the network by the terminal. The authenti...
