A method, system and terminal device implement locking a terminal device onto a network. This method comprises a procedure of locking onto the network during accessing the network, namely performing locking-onto-network configuration verification in a network accessing authentication process (401 to 403), and if the locking-onto-network configuration verification is successful, allowing for verification for an authentication certificate (404 to 406), or else refusing the terminal device of access to the network (11). The method, system and terminal device in the present invention perform locking-onto-network configuration verification when performing authentication, and the terminal device and server uniformly configure a locking-onto-network character string, and thus it has a great security. Besides, the present invention also can implement unlocking and locking again after accessing the network via an air interface management in the OTA way, and thus it has high flexibility and applicability, and can well satisfy the requirements of 4G networks such as the WiMAX network and LTE network and so on. |
