USER DEVICE VALIDATION METHOD, DEVICE IDENTIFICATION REGISTER AND ACCESS CONTROL SYSTEM

摘要

The present invention discloses a method for validating user equipment, a device identity register and an access control system. Wherein the method for validating user equipment comprises: setting a central device identity register shared by different networks, wherein illegal user equipment identities are stored in the central device identity register; the central device identity register receiving an ID validation request from a mobility management entity, wherein the ID validation request carries ID parameters of a user equipment; the central device identity register validating the validity of the user equipment according to the ID parameters, and returning a validation result to the mobility management entity. In virtue of the present invention, the accessing of the illegal non-3GPP network user equipment which is capable of accessing 3GPP network to the 3GPP network is able to be controlled.
