Title: AUTHENTICATION METHOD, DEVICE AND SYSTEM FOR USER EQUIPMENT
Abstract:
Disclose are an authentication method, device and system for a user equipment. The method comprises: first, a user equipment receiving a random value RAND and a cognitive code AUTN in an evolved packet system (EPS) authentication vector sent by a network side device; when an operating mode of the user equipment is a long-term evolved node LTE Hi operating mode, the user equipment performing authentication based on the RAND and the AUTN. In the authentication process, the user equipment ignores a verification result of a separation bit of an authentication management field (AMF) in the AUTN; or, the user equipment does not verify the separation bit of the AMF. The present invention is applicable to the field of communication systems.
