<p>The present invention provides a method, device and system for unlocking a mobile terminal by an operator. The method includes the following steps. An operator device receives an unlocking request from the mobile terminal, wherein the unlocking request carries unlocking identification information; the operator device determines to allow the mobile terminal to unlock according to the unlocking identification information, and queries, according to the unlocking identification information, a cryptographic key list database pre-stored in the operator device to obtain an unlocking cryptographic key; and the operator device sends the unlocking cryptographic key to the mobile terminal to ensure that the mobile terminal carries out the unlocking according to the unlocking cryptographic key. According to the present invention, the problem of relatively poor safety of unlocking by a mobile terminal under the control of an operator is solved, meanwhile, the unlocking process is simplified, the speed of responding to an unlocking request of the mobile terminal is quickened, and the satisfaction of using the mobile terminal by a user is improved.</p> |
