Method, system and device for authenticating access of IMS (internet protocol multimedia subsystem) terminal to IMS network

Abstract

The invention provides a method, a system and a device for authenticating access of an IMS (internet protocol multimedia subsystem) terminal to an IMS network. The method comprises the following steps: building a PSTN (public switched telephone network) channel between the IMS terminal and an IMS registration and authentication server; receiving registration and authentication codes from the IMS registration and authentication server through the PSTN channel, and storing the registration and authentication codes; and sending an authentication request which carries registration and authentication codes to the IMS registration and authentication server through the IMS network so that the IMS registration and authentication server judges whether the registration and authentication codes corresponding to the IMS terminal in the IMS registration and authentication server are the same as the registration and authentication codes which are carried in the authentication request and performs the corresponding processing according to an authentication response.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to an authentication method, system and device for an IMS terminal to access an IMS network. Background technique [0002] At present, the existing Internet Protocol (Internet Protocol; short: IP) multimedia system (IP Multimedia Subsystem; short: IMS) terminal device mainly uses the Hyper Text Transfer Protocol (Hyper Text Transfer Protocol; short: HTTP) Digest mechanism Authentication to access the IMS network. Specifically, the IMS terminal sends the registration number and password entered by the user to the IMS registration server in the IMS network for authentication. If the authentication passes, the IMS terminal can directly access the IMS network; if the authentication fails, the IMS registration server is rejected. The terminal device accesses the IMS network. [0003] However, the authentication method of the HTTP Digest mechanism requires the user...
