Abstract
An authentication system, method and device are provided in the present application. The authentication system includes an Application Server (AS) for providing non Internet protocol Multimedia Subsystem (IMS) service, an authentication gateway and an IMS terminal. The AS forwards a connection request message sent by the IMS terminal to said authentication gateway, the authentication gateway sends a obtained first random number to said IMS terminal through the AS, the IMS terminal generates a first Response (RES) value according to the first random number and sends the generated first RES value to the authentication gateway through the AS, and if the received first response value and an obtained Expected Response (XRES) value is found coincident after being compared by the authentication gateway, the authentication gateway determines that the authentication to the IMS terminal is passed, and indicates the AS to provide non IMS service for the IMS terminal. By using the technical solutions of the present application, solved is the problem existed in prior art that non IMS AS needs to authenticate each of IMS terminals respectively for obtaining non IMS service and thus reducing the …
