Method of selecting right identification mode at network side

Abstract

This invention discloses a method for selecting authority authentication mode by the network including: HSS feeds back the information supporting the early IMS mode of authority authentication, the information supporting the 3G-authority authentication mode or the failure information directly to S-CSCF based on the received required information in the authority authentication vector required information from S-CSCF and the kind of the requiring user, if the information is from the first two, S-CSCF feeds back the information of permitting or refusing access to the user based on the authority authentication result after authentication with related modes, if ití»s the last one, then S-CSCF sends the information of forbidding the access to the UE directly.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method for selecting an authentication mode by a network side when a user uses a multimedia subsystem (IMS) network. Background technique [0002] With the development of broadband network, mobile communication is not limited to traditional voice communication, but through the communication with data services such as presence, short message, web page (WEB), location information, push service (PUSH) and file sharing, etc. Combined, mobile communication can realize services of multiple media types such as audio, video, picture and text, so as to meet various needs of users. [0003] Organizations such as the 3rd Generation Partnership Project (3GPP) and the 3rd Generation Partnership Project 2 (3GPP2) have successively launched the IP-based Multimedia Subsystem (IMS) architecture, which aims to use a A standardized open structure to achieve a variety of multimedia a...

Problems solved by technology

[0011] Although both 2G-based users and 3G-based users can access and apply the services in IMS, and the ways of accessing IMS based on 2G and 3G are compatible, the current problem is that for systems that have been upgraded to 3G In other words, after the core network in the IMS receives the user's registration request, it does not know which authentication method should be used to authenticate the accessing user, but directly applies the 3G-based authentication method to authenticate the user.

In this way, if it is a legitimate 2G user, it cannot access it. This is because the authentication method for 2G users on the network side is different from that for 3G users, and 2G users cannot pass the authentication method based on 3G. At this time, the network side will consider the user as an illegal access user, thus causing legitimate users to fail to access normally, making the fault tolerance of the network poor
