<p>A method for detecting whether or not a universal integrated circuit card (UICC) is used on an authorized device, comprising: when a core network node receives an attachment request of a user equipment, establishing a secure connection thereto, transmitting an identity request message to the user equipment, receiving an international mobile equipment identity (IMEI) and device authentication data returned by the user equipment, and transmitting the IMEI, an international mobile subscriber identity (IMSI) of the UICC on the user equipment, and the device authentication data to a home subscriber server (HSS)/home location register (HLR) via an update location request; the HSS/HLR performing the following detections: detecting whether or not the IMEI and the IMSI are an authorized IMEI/IMSI pair, and/or, detecting the device authentication data on the basis of a device root key corresponding to the IMEI to determine whether or not the IMEI is valid. The present application also relates to a system and the user equipment for detecting whether or not the UICC is used on the authorized device.</p> |
