Patent ID: 8539607

Claim:
A method for validating user equipment, comprising: step 1, after a user equipment accesses a network, a device on a network side sending a request message to the user equipment in order to obtain ID parameters of the user equipment; step 2, the user equipment receiving the request message, and sending a response message to the device on the network side, wherein the response message comprises the ID parameters of the user equipment; step 3, the device on the network side sending an ID validation request message of the user equipment to a device identity memorizer, wherein the validation request message comprises the ID parameters of the user equipment; step 4, the device identity memorizer receiving the ID validation request from the device on the network side, validating the validity of the user equipment according to the ID parameters and returning a validation result to the device on the network side; wherein the device identity memorizer is a central device identity register, which is configured to share illegal user equipment identities in a 3GPP network and a non-3GPP network.
