Abstract

The invention provides a locking method, an unlocking method and a device thereof, network equipment and a communication terminal. The update method comprises the steps: transmitting a locking inquiry request to the communication terminal; receiving the current locking information returned by the communication terminal, wherein the current locking information comprises a state mark which is used for indicating whether a network is locked; judging whether the communication terminal is in a locking state according to the state mark; if a judging result is an unlocking state, transmitting locking information of a locking network to the communication terminal; and the locking information comprises a network mark of the locking network to lead the communication terminal to lock the corresponding network of the network mark. The invention locks or updates PLMN by a wireless configuration method, unlocks by the wireless configuration method, does not need to replace a data card, does not need a network to issue tools regularly, can be easily realized, save cost, strengthen the competitive power of the data card and is more convenient to operators and users.

Description

technical field [0001] The present invention relates to a communication network system, in particular to a locking method, an unlocking method and a device thereof, network equipment and a communication terminal for performing network locking on a terminal equipment data card. Background technique [0002] At present, in order to develop users, network operators have adopted various marketing strategies to provide users with various differentiated and personalized services. In order to protect their own network rights and interests, most operators require locking the SIM card (SIM LOCK) when the user purchases a data card. The purpose of locking the SIM card is to limit the Subscriber Identity Module (SIM: Subscriber Identity Module) of the operator. Use on data cards. That is to say, if the SIM card issued by the local operator is inserted into the data card, it will be confirmed as a legal SIM card by the data card, and if the SIM card is not issued by the operator, the S...
