Abstract

The invention discloses method, device and system for unlocking a mobile terminal by network operator. The method comprises the steps of: receiving an unlocking request from a mobile terminal by an operator device, wherein the unlocking request carries unlocking identification information; determining to allow the movable terminal to unlock by the operator device according to the unlocking identification information, and inquiring a secret key lift database pre-stored in the operator device according to the unlocking identification information to obtain an unlocking secret key; and sending the unlocking secret key to the mobile terminal by the operator device to ensure that the mobile terminal carries out the unlocking according to the unlocking secret key. According to the invention, the problem of poorer safety of unlocking by the mobile terminal under the control of an operator is solved, meanwhile, the unlocking process is simplified, the speed of responding the unlocking request of the mobile terminal is quickened, and the satisfaction of using the mobile terminal by a user is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method, device and system for an operator to unlock a mobile terminal. Background technique [0002] In recent years, with the rapid development of mobile phone technology, operators have put forward higher requirements for customized services. Operators often put forward lock system requirements such as network lock / lock card / lock terminal when customizing mobile terminal products. Among them, the definitions of lock network / lock card / lock terminal are as follows: [0003] Locking is a special requirement for the terminal. After the mobile terminal is locked to a specific card, it is required that the terminal can only use this specific card, and other cards cannot be used normally on this terminal. [0004] Locking the card is a special requirement for the card. When the card is locked, it is required that the card can only be used on a certain terminal and cannot be used o...
