AUTHENTICATION METHOD, DEVICE AND SYSTEM FOR USER EQUIPMENT
First Claim
1. A method for authenticating user equipment, comprising:
- receiving, by the user equipment, a random value RAND and an authentication code AUTN in an Evolved Packet System (EPS) authentication vector sent from equipment at a network side; and
in a case where an operating mode of the user equipment is a Long Term Evolution Hi (LTE Hi) operating mode, performing authentication by the user equipment based on the RAND and the AUTN, wherein in the authentication, the user equipment ignores a verification result obtained by verifying 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.

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 disclosure is applicable to the field of communication systems.

6. A device for authenticating user equipment, comprising a computer readable storage medium and a processor, the computer readable storage medium having a program that when run comprises:
-
a receiving unit, configured to receive a random value RAND and an authentication code AUTN in an Evolved Packet System (EPS) authentication vector sent from equipment at a network side; and an authentication unit, configured to perform authentication based on the RAND and the AUTN received by the receiving unit in a case where an operating mode is a Long Term Evolution Hi (LTE Hi) operating mode, wherein in the authentication, the authentication unit ignores a verification result obtained by verifying a separation bit of an Authentication Management Field (AMF) in the AUTN;
or, the authentication unit does not verify the separation bit of the AMF. - View Dependent Claims (7, 8, 9)

11. A device for authenticating user equipment, comprising:
-
an acquisition unit, configured to acquire a Universal Mobile Telecommunication System (UMTS) authentication vector, wherein the acquisition unit is further configured to acquire an Evolved Packet System (EPS) authentication vector based on the UMTS authentication vector, in a case where an operating mode of the user equipment is a Long Term Evolution Hi (LTE Hi) operating mode; and a sending unit, configured to send a random value RAND and an authentication code AUTN in the EPS authentication vector acquired by the acquisition unit to the user equipment, so that the user equipment performs authentication based on the RAND and the AUTN. - View Dependent Claims (12, 13)
