Embodiment Construction

[0060] The present invention provides a mobile access user agent (Mobile Access User Agent, MAUA) network entity, which has the following functions:

[0061] Process circuit domain signaling with the wireless access network, and provide mobility management and location management functions for traditional mobile terminals (non-IMS terminals) roaming underground under the management of MAUA;

[0062] As a SIP user agent, instead of the traditional mobile terminal roaming in the MAUA management to perform SIP registration and initiate / receive SIP sessions in the IMS domain;

[0063] Two-way conversion between circuit domain signaling and SIP signaling between the wireless access network, so as to complete the function of connecting traditional mobile terminals to the IMS domain;

[0064] It has the function of providing charging information to the IMS domain, and can provide a charging interface;

[0065] In the case of a media gateway, the terrestrial circuit resources and int...

Abstract

The invention discloses a log-on authentication method for a non-IMS mobile terminal access IMS domain including: a non-IMS mobile terminal user accesses mobile agent initiates registration request and receives the authentication random number from IMS domain by the access mobile user agent, carries out calculation on authentication according to the random number and then transmits the result to the IMS domain by the mobile access user agent for authentication. The invention also discloses a mobile access user agent device including: a first signaling process module, a signaling conversion module and a second signaling process module to interact between the non-IMS terminal and the IMS domain to realize format conversion between information from the IMS domain and non-IMS terminal supported information.

Description

technical field [0001] The invention relates to the communication field, in particular to an authentication and registration method and device for a non-IP multimedia subsystem (IP Multimedia Subsystem, IMS) mobile terminal to access an IMS domain. Background technique [0002] At present, the IP Multimedia Subsystem network defines in the standard protocol to use the AKAv1-MD5 algorithm to authenticate users. Therefore, if a user wants to use the services provided by the IMS network, he must have an IMS Subscriber Identity Model (IMS Subscriber Identity Model) that supports this algorithm. , ISIM) card. However, because the User Identity Module (UIM) card or SIM card only supports the traditional authentication algorithm and does not support the AKAv1-MD5 algorithm, the existing IMS network does not support the cellular network authentication and voice encryption algorithms of traditional terminals. (Cellular Authentication and Voice Encryption, CAVE), therefore, those use...
