Abstract: The present application provides an access method, device, and system of UE, and relates to the communications field. The method is performed by a first network device on a 3GPP network, including: receiving, by using a second network device on a non-3GPP network, an access request message from the UE; generating a first NAS verification code according to an identifier of the UE and a NAS security context of the UE stored in the first network device; if the access request message includes a second NAS verification code, detecting whether the second NAS verification code is the same as the first NAS verification code; and if the second NAS verification code is the same as the first NAS verification code, sending an access key of the non-3GPP network to the second network device.
